I’m not an engineer but my wife is. One of her coworkers actually helped design the engine layout of a fort pickup truck back in like the 70s (guy is pushing 80 and refuses to comply retire) and he was told back then to intentionally make certain aspects of the layout harder so it would be more difficult for diy repairs and they would have to get it professionally serviced… this was 50 years ago THEN! I cannot imagine how much BS corporate culture is pushing that now.
@@marke8930wow dealer mechanics. Geez, I wonder what would a low class working family with no money to afford a dealer mechanic have to do to be able to fix something dealer mechanics find difficult and/or have all the special tools they need to fix some contraption that could be easily resolved by designing it simpler 🤔🤔🤔🤔? Kinda sounds to me like repairs are hard to DIY on purpose and that money was supposed to go for the dealer they were only thinking about. Considering your dealer mechanic making repairs vs a normal slim-to-none car knowledge person trying to DIY issues are two totally different concepts.
I can tell you exactly what happened as an automotive engineer. Meeting 1: “we have a service issue, we need to access this fastener for our 75,000 mile service interval. Okay we can put a hole there”. Meeting 2-30 the sheet metal team was not talked to by the engine team and the fastener was moved for some other issue. 1.5 years later they discover the problem in the second round of test vehicles. “Oh shit we already paid for the sheet metal dies and they have a 20 month lead time” So they quickly implement a service procedure fix to get around the issue. Guarantee you the engineer who moved the fastener told his manager. I also guarantee you that manager or the sheet metal engineering manager didn’t do their fucking job. Neither did the systems engineering manager who is supposed to be tracking this kind of stuff. Ask me how I know.
You can't tell us to ask a question and not answer it.. also, when you do answer it can you reply to this message so I can see your answer? Thanks bud... very interesting breakdown.
@@nathanstewart2168 I’ve sat in plenty of these design reviews. I had a similar issue on the rear axle of the latest GM trucks where they could not be made because someone did not think about a new process and did it the old way anyway. These cars are designed by teams of 3-4,000 people. The left hand doesn’t know what the right hand is doing because they are not well run. It has gotten even worse now that they don’t pay people to stay and turn-over is high.
As an engineer I can explain. The tensioner was placed. Then the hole was placed to allow for tooling. Then an issue arose later requiring a slight translation of the tensioner's location and the engineers failed to annotate the tooling hole association. These associations are fixed in a lot of model-based definition designs today by forcing an association between the CAD parts in programs like CREO. Anyway...it isn't that they hate you...they just don't think of you at all.
As a machinist who makes the stuff engineers come up with, I agree. Engineers simply are oblivious to how anything is made and draw up prints like two year olds. I can't tell you how many prints I've had to correct, guess, fix, re-make, make calls on and the engineers just sit there with their mouth hanging open. I don't understand why engineers make so much money. I do all the work.
@@Moonless6491 You can just do it all. Whence cometh being a lowly machinist? You can start your own company. Probably missing out on a big opportunity.
I think that placing a hole in front of a screw does not cost more than placing it 3 cm higher... Stop making excuses for these guys. They are just ignorant and incompetent.
@@Auroche no it doesn't lol, every change involves moving other components around. Sometimes to make it easier to access, we design a more complex system to reduce the labor time, but it requires more material, and this more cost. This often gets shut down in the favor of saving money, and the labor time gets extended because we had to take shortcuts to save material. Then the mechanics get screwed over because the insurance often only allows a certain amount of billable hours. If the insurance only covers a 5 hour repair, and it takes the Mechanic 9 hours, the mechanic only gets paid 5 hours
Engineer here. I'm actually the one that designed the frame to have that clearance hole. I remember modelling it while rubbing my shitty beard and going "yeah.. fuck you"
@@MotorcycleRebuildsyou clearly don’t listen. He said that you have to drop the motor 3 inches. So the motor mounts have nothing to do with this piss poor design.
That’s your problem you guys think oh it works on my computer must work in real life. Well 9/10 it doesn’t. So how about put some actual thought into the shit y’all design and stop leaving us trade guys to fix your dumbass ideas. Cause it’s not just you design mechanics that do this shit. Guys that design intricate builds love to do shit that just makes absolutely no sense.
Engineers are at the mercy of the company. They say make them think an attempt was made, but in the end still may just decide to go to the dealer for repairs.
No, they’re not. The company doesn’t have any idea why engineers do what they do. It’s why they hired engineers; To do stuff they don’t understand. They expect engineers to improve their product gradually, but ultimately, it’s the engineers that decide how things get done.
@@knifedance2402 Wow. Where the hell is a company that has so little control? All those engineers that were hired have engineers as bosses. Those bosses are the bridge between the company and the work staff. Im one of those bosses.
This is exactly the comment I was looking for. Engineers only give a fuck about how complex they can make a system so they can feed their massive egos. I've worked with dozens and dozens of engineers over the years. I have yet to meet one who preferred simplicity over complexity. Not a single one.
And that is because they don't know how to actually speak or talk anymore, and forgot to send the email to the other team. In other words, all they care about is showing up to collect a paycheck like anyone with a job anywhere these days.
actual automotive engineer here. These drive-trains are often shared amongst several vehicle programs and these tolerance issues would require retooling the drive train or chassis for each program which costs time & money. this isn't done intentionally, its a side effect of saving money.
The real answer. Shit comes up you have checkpoints where some dude needs to make sure you can finish a product in time, and sometimes in the crunch you bring something out that works good enough for THEM and they want to get it out NOW. Also sometimes the timeline that they give you when you're doing your initial design isn't the timeline you're actually getting. Or it just straight up isn't enough time for the shit they want from you from the very start.
Holy Christ if i had the amount of time needed to make sure everything was correct, this sort of stuff wouldn’t be an issue. Not to mention struggling to give two rats when the pay sucks.
I want to believe this but when literally every vehicle out there has at least a few, if not several issues like this I lean towards it being intentional rather than rushing or incompetence. With the collective decades of experience that an engineering team draws on when designing something as complex as an automobile, typically coming together over the course of several years, I have doubts that the stupid engineering choices boil down to "we were getting rushed".
i call BS on that, engineers couldnt identify a problem if it had bells and whistles on it with a sign saying hey you dumba$$ im a problem grow a braincell and think of a way to fix me
Two possibilities: 1. They did it on accident. Trust me, that is possible. 2. They did it on purpose to piss of mechanics "encouraging" owners to bring it into the dealers. You be the judge.
Well, that’s sometimes all we have. Maybe the hole was lining up with the bolt when it was new. But engine and transmission mounts do collapse over time and things get out of line.
@@TimJaeger-lh3yh I feel you... But a good engineers usually test things. Oh I forgot, testing is expensive. And good, experienced engineers who know how things work, ask for so much money! So the management says - why hire such guy, when we can have someone straight after studies, asking for 1/3rd of that wage? And let's give him our toughest and most complicated stuff to design. Especially when he's inexperienced - he will not whine about why this is too thin, why we can't do it this way, why we can't weld that cover over the most service requiring parts of the machine... :D
Maintenance and serviceability is purposely engineered like this to make difficult for one to repair these newer models unless the are a qualified ASE certified mechanic. Meaning: more money is to be made for the automotive industry. What this young lad is pointing out is painfully obvious of being a shitty engineering design. Welcome to the real world young blood. I say let's put Jesus Christ in charge instead of these greedy halfwits that rule over us. Sound good? 😀👍
Used to work as a mechanic. Customer pays for the book time it takes to complete. If it says it takes 5 hrs then you get paid for 5 hrs even if it takes you 10
As a mechanical engineering student who worked in the auto repair industry, I couldn’t agree with you more and I have made it my life’s mission to make this right.
youre gonna feel crushed when you get into industry and realise that youre gonna be on a team of 6 people designing an air filter and have no real power in the overall design of the car.
That's not an access hole. That is a fixture hole that is used when welding the body together at the factory. If the engineers were aware you were using it as an access hole they would figure out a way to delete it and make you remove the engine.
I laughed way too hard at this 😂 but it's accurate. They would say it's not rated for torque to be passed through the structural tin can they cobbled together
It's the same in civil engineering lol. Architect: This is my finest design and it will look amazing! Mr. Civil, make this work! Civil: *Looks at existing contours* 😨😨🫨🫨😵💫😵💫
I completely relate to this. I’m an engineer who actually likes building & repairing things, but I firmly believe that engineers should be required to work hands-on with their own designs.
Yeup. Am an engineer in the ag industry. I do hands on with almost all of my designs. The hard part comes when some companies have unions. Engineers can't go hands on, cause you're "taking the job" of the techs...
That's the biggest issue, not many engineers get field experience. I'm an electrical engineer at a utility and still have to get out to the field or talk to construction about things. Isn't til you get some field work that you really get the full picture
They don't let you do that anymore because it is 'too dangerous' and 'you aren't trained for it so you can't do it' like they said that my engineering team can't solder on its own anymore because we need lead solder and lead is apparently too dangerous for people with phd's to handle because they weren't specifically trained for that.
3 different engineers designed the engine, support and engine mount. It's likely the position of the engine was changed late in the design after the hole location was finalized in the support. The issue wasn't caught until preproduction.The program manager justified not scraping the supports and delaying the program because "all you need to do is drop the engine". The mistake was made by a communication break down in engineering, it was made permanent by management.
I used to work for a car dealership back in OKC. As an employee i had to sit in on a few dealer meetings with corporate headquarters. These "hard to work on" designs are done intentionally at the explicit request of the dealers. The intention is to drive revenue to the dealership. Most if most all auto manufacturers do it. The dealers would complain directly to corporate in these meetings about how easy a particular car, sub assembly, or part was to replace or fix. Certain models of cars didn't get priority sales placement on the dealership lot, specifically because that particular model did not generate enough continuing or return revenue. There actually exists a book written by the auto manufacturer that estimates the amount of expected profit based on the type of vehicle, mileage and when parts are expected (engineered) to fail. I've sat in when dealers have threatened lawsuits against corporate because they weren't making enough money on repairs (cars weren't falling apart fast enough, or customers were taking them to independent mechanics to get the work done for less)...#FACT! There's a reason cars are hard to work on and it isn't because they are infinitely complex.
Im going to presume theres another engine option available on that vehicle where the hole lines up, but they didnt bother changing the body to account for those changes in other configurations.
@@Giborski well a company that is not a piece of retarded shit would just have 2 holes. One would work with one engine option and other would work with other engine option.
What probably happened is the team working on the tensioner forgot to mention to the body people they moved the tensioner slightly because they don't deal will access issues and don't have to think about it. The two teams designing this aren't at fault, it's the 3rd team of system engineers that failed to notice and by the time it was noticed, during manufacturing probably, it was too costly to change according to the accountants, so blame them as well.
Most engineering descriptions of an engine is based upon a complete disassembly, even down to constituent parts of items you don't need to take apart. It's not that the engineers hate you, it's that you don't work their way.
Lol they literally type out the service procedures step by step with pictures so the field technicians don’t even have to pay close attention one time or remember how to do anything, except for how to read and follow directions. Some just forget they can read over time and some live in complete denial of the service manuals existence. When you can’t figure a repair out just ask yourself, which one are you. And then go read some tsb’s and search for service procedure updates and check for special tools. If after all that you are still baffled only then can you start cursing the engineers in preparation for calling tech support hotline.
I'm actually an aircraft mechanic but I've done lots of prototype work where I've had to work closely with engineers. I've asked engineers why the hole in the bulkhead that's used to remove a bolt can't just line up with the bolt rather than making the mechanics remove half the accessories, or jack the engine to get to that bolt. They just look at me like I've asked the stupidest question ever. It's a matter of respect and that's why the old engineers tend to be successful with a whole lot less effort, they listen. I get the impression that most engineers never even talk to the mechanic. I'll have to admit that some manuals are very well written but the design process rarely seems try and simplify the maintenance process. In the end, the customer is the one who suffers.
@@jaxturner7288I probably have more training hours and certifications than you could even dream of. If you've done vehicle repairs or recalls half the pictures are not of "complete" vehicles they're of staged models. The repair procedure and TSBs can only get you so far The fact is engineers only know X+Y=Z (because math said so)...
@@jaxturner7288As a mechanic and restoration hobbyist you’re dead wrong And I could bet anything that not only have I been working on cars And tractors probably longer then you’ve been alive I’ve one hundred percent read more service manuals Engineers simply make mistakes due to oversight. It’s not unheard of it’s not because people can’t read it’s because it’s just a simple disconnect from the reality of having to service or maintain something they’ve designed. An engineer can be overwhelmed with figuring out how to get everything to fit and function properly in a design so it’s only natural that sometimes quality of life for servicing is put on the back burner It’s a pain in the ass but it’s just how the world is it’s not like engineers Are dumb or have some sort of grudge. It’s just oversight it happens with everything But boy let me tell you when you work on some things it really really does seem like the engineer was huffing glue but I think we usually know deep down that nothing can be perfect and every product And profession can and will have its own quirks
@@TealJosh that's normally true depending on the project. But I've seen a few engineers who are very careful and get it right the first time more than not. But these use a lot of time in doing so. Others just want to buzz on our and get home to a beer every night like a young construction worker. These tend to be more sloppy and take little pride in their work. I often wonder why they got into engineering, with no passion for the work at all. For 13 years I lead an engineering team. One of my engineers made a lot of mistakes and I started to get a lot of complaints from our technicians. I took them seriously and listened to what they had to say. I asked, "how much time per week would you say you have to fix his mistakes" to which they responded, "about two to four hours and sometimes s little more". I thought about this for a bit and responded, "this engineer does three times the work of my other engineers. I don't want to ask him to slow down because he is very productive. But I will spend some time with him to improve his accuracy". I asked for a few months to improve things and the technicians agreed. The engineer did show down a little and his accuracy really improved. This engineer was one of the few who took personal responsibility for high output and kept an eye on the calendar. He was like a unicorn and I miss him.
Honestly, my theory is that it’s made much harder to prevent the layman from doing the maintenance themselves. Get people to take it to the dealership.
No, it was designed to be installed as part of the front assembly, which includes suspension and steering parts. It was designed to just slip up and be bolted into place. They never thought about anything other than time for install and saving money by using already existing parts to cut costs for higher profit margins out the door. That may not have been the initial design engineers thought as that part gets warped once production engineers get their hands on it as they have to find ways to get the same result at a cheaper price.
The engineer who designed that engine never imagined 15 years later they'd still be using it and cramming it into a different car. So, blame the bean counters.
Slapping engineers will result in access holes being moved sideways from that point on. Not only will we make you drop the engine, we'll force you to tilt it as well.
As a nissan owner I agree. I feel like they only design shit with the part there bolting on and the peice it bolts onto completely ignoring everything else around it
I highly recommend for those torx bolts to get a set of grip edge torx bit sockets. I’ve stripped those out with regular ones before and when I bought my set of grip edges, haven’t had an issue since. Highly highly recommended
They didnt even think about that. They designed this car to go together quickly on a line nobody gives a shit about fixing it when it breaks. Nobody has in a long time. And i get it, ive done this job. Wish id had that badass headlamp when it was my turn
As a software engineer, I can confidently say it was because we have never once spoken to the mechanical engineers that sit about 60 feet away from us.
@@zbou23as an engineer, it's because they probably aren't even on the same continent as each other and one part was designed for a completely different car.
From what i know its mostly the ceos and stockholders who make this happen. The workers and designers would rather it work as intended and make something good.
Accountants and managers have more influence in the decision making than the engineers. I always try to k.i.s.s. but if someone says otherwise with more clout I can do shit about it
No, the people at the top WANT it to be as hard as possible to repair the cars, so all the dealer specfic tools are needed to fix your car. They want them to be as hard to repair as cell phones
The person who timed that job for The Labor Time Guide, if your shop uses one, has the responsibility for the correct calculation. If the calculation for labor time is too short they must be blamed not the engineer.
An unfortunate truth for car mechanics is that most of these “design flaws” were not even thought of in the engineering process. They designed the car for assembly. Quick assembly on an assembly line is what these corporations care about. The more they can crank out, the more they can sell. I know, it sucks, but that’s how it is.
theres less than an inch clearance to put those attachments on and TORQUE it in a small area. this is not smart and doesn’t convince any one human or otherwise that we are smart
@@regiscidal9078 pretty sure all Torque spec's are just, so tight you cant turn it by hand and 3 taps with a hammer. Of course the factory wouldn't tell you.

@@drflannelxd904 I don't think engineers set out to create difficulty on purpose. Through thousands of design decisions things get overlooked or compromises are made due to timelines and budgets. That said, I think there's business reasoning that repairs that require more labor and skills result in higher revenues for dealerships... So, perhaps they don't lose sleep when things like this arise?
@@gunsite4575% really because at this point conspiracy theories are news in a few months. Like whenever a "conspiracy theory" about covid came out. 4-6 months later it was fact all a sudden.
Engineer definitely identified the issue in the design process. Told lead engineer of the issue. Was told to come up with a solution. They did so. Bean counter then came in and said make it even cheaper. The end
Thats what happens when you give 30 people access to a cad file and you have a huge pile of notes that you cant get through and you don't let the first shift polish the design on top of a huge time crunch, engineers didn't do anything on purpose
Ok thats fair on an engine, but when you have to disassemble a whole door for a fuckin door handle. Only like five things in a car door, why they all gotta cover the one torx bit that needs to come off to switch the handle. On second thought, the fact cars use torx bits is proof engineers do this shit on purpose. I have the same hex socket set, flat head, and Phillips head bits from when i started years ago, any torxbits i use regularly are max 8 months before they sheer, and the bolts strip more often.
It's immaterial that you need to replace a torx bit slightly more often if it speeds up automated mass production and leads type a more consistent torque. Let's do it the dumbest way possible because it's easiest for you mentality. The cost of putting one straight blade screw on there just so you can have a slightly easier time is in the realm of tens of thousands of dollars minimum.
Guys, you don't understand, it's not the engineers fault, its the fact that the project manager isn't an engineer so they don't care that the car isn't done.
You pretty much got it. Budget allows for a certain amount of labor, then the head of the dept says "send the cost to maintenance" because they're only really worried about their bonus, they might not even be there next year.
Hands-on experience would probably benefit many design engineers, though who knows if that's the issue here. A coworker told me about working factory maintenance in another country, where all the plant engineers were non-degreed former maintenance guys--everything was built to maintain and easy to service (this was for an internationally known beer brand). By contrast, our brand-new plant in the USA had many things difficult/impossible to reach without cutting or other absurd steps. Crazy!
It’s not to piss you off. It’s to increase the repair costs, eventually to make the customer prefer to buy a new car instead of holding onto the old one. Climate change they said… Global warming they said… Emissions they said. ..
Engineer here my man....mistakes and oversights happen (usually at later stages of design due something that's not relevant at that time). We call these lessons learned. They usually get fixed in later generations of a current model. This is why you're better of buying the last model of a given shape (usually 3 to 4 yrs in) before a complete redesigned model is introduced in the market. I promise it has nothing to do with hating you. In fact, on day one of my first job, my manager told me the best way to learn how to design something better is by watching the people that have to handel and use them. That's you.
Imagine, engineers are people too and mistakes are made everywhere. Also sometimes a multitude of unfortunate things come together to create a problem.
Mistakes are easier to track in the later stage of design, the regular occurrence is a sign of a lack of effort altogether. My gas Samsung oven died because engineers didn’t glue a pennys worth of metal to the chipset that controls the oven. What do ovens do? What do chips hate? The anecdotal evidence is stacking up that y’all are designing things to be thrown away. Plain and simple
This is a funny video, but we promise it’s not on purpose 😅 (Design Engineer here). We’re faced with the same pressures everyone faces. Management wanted it yesterday and we have a billion priorities. Mistakes happen. Also, a bunch of engineers have never worked on cars themselves. They’re great at math and design, but don’t know the troubles of maintenance… Good video. Keep calling us out (even though i’m not in auto industry) lol
As a computer engineer, I completely agree any engineer worth their salt should be able to put together and take apart the thing they design before presenting it as a possible solution ask by the company.
I think most of these kinds of things happen because it's different engineers working on different subsystems of the car at the same time and they never communicate between eachother very much. And they are engineered to be cheap and easy to assemble at the factory.
@@HellcatGamin you do know there are more than 1000 people that are involved in designing, and developing cars. So no it is not intentional just managed poorly
There are actually mechanics that prove the ability to service. It's a requirement to pass this tollgate. There is a procedure you are paid to do, so use it..
I loved how Audi did this on the older models. you get your audi tool for the job, fit it on the front, and then you can take the whole front of the car and drag it out, giving you plenty of room to work on the front of the engine.

I got an answer for that! In one of the revisions, the bolt was lined up with the access hole. One thing lead to another, and they had to move the tensioner bolt, but forgot to move the access hole before the plans got approved and sent off for production. This happens a lot when you run into unexpected issues and have deadlines to meet.
@@UN4SS1GN3Dnot really. It’s extremely unrealistic to have to do a redesign and then recheck every single part and potential access port affected before resending. It’s still a shitty mistake to make, but that’s how iterative designing works
Welcome to capitalism and its shareholders requiring their short-term quarterly profits at any cost, and thus forcing the workers of the companies they're investing in to work quickly and release even quicklier, disregarding any issues that don't directly lead to major failure.
I honestly think these companies are doing it on purpose the same way they're purposefully doing it with technology, phones in particular, with the idea being the harder they make it to fix your own stuff, the more likely you are to pay them to fix it for you like at a dealership.
In a few years, you won't be able to change brakes! Some buick/chevy crossovers if you disconnect the battery.. the dealer has to flash the memory! $$$$$$$$$
I’ve been repairing phones for about 10 years. It’s way easier now than 10 years ago, and parts are easier to get. Heck, now you can even find a high res video explaining how to replace surface mounted components.
This probaply there for the timing chain replacement, often where i work we do tensioner and pulleys to, and since we have to Drop the engine down. Pretty obvious but i rather make it loose earlier to
It's a cold world, but I don't believe the car makers could care less. They don't pay for a costly repair years down the road, paid for by the consumer. They only care about selling the vehicle and making money. I'm a mechanic and that's the conclusion I've come to after many years of wrenching.
I understand the frustration...usually there's a few cuss words and a busted knuckle before I just drill another hole and then ask myself why the hell didn't I do that to begin with.
As an engineer: Don't just drill holes into the body of a car... We do a lot of computer modeling to end up at the exact shape a car body is... Drilling random holes into a cars messes with that a lot. :(

@@jeramypompa You figure it out. They don't want you fixing it. They want you to go broke, paying a dealer shop and/or buying an overpriced one time tool, and/or buy a brand new even bigger piece of junk. Planned obsolescence.
My dad was a mechanic, and his theory was money. He figured they make it hard for the average person to do it so that you end up taking it to the dealership so they can charge insane rates to work on it.
This used to be true. The video however demonstrates a perfect example of the disconnect between the engineer/designer and the person that reads the drawings and makes the cuts or produces the part. This routinely happens in construction all the time between the architect and the actual builders. The builders are typically the ones that read something wrong they caught the mistake too late to fix it so they had to come up with some weird fix that stands out lol.
Mechanics used to be mechanical engineers, now they are just part changers. They change parts that suffered resulting damage, but fail to correctly diagnose the cause of failure, thus not correcting or truly repairing the problem.
I was woking on design of locking system on some van. It shared the ground wire for locking motor and locking sensor, and used the same wireing form a car. It being a van, it had more powerful locking motors, so higher current caused locking sensors to glitch, sometimes. But we were notmallowed to chage the wireing. So we had to engineer our way around the problem by ignoring sensor signal for 1s. I hated my job so much.
@@schreadersautorepairllc.6202Unless you're planning to pay the engineers salary, that's not how it works.

I've argued my case when it's something egregious, but I don't have the time to fight about every single part that I design.
This is why I like working on older cars. They were designed with maintenance and repairs in mind. They wanted you to enjoy your vehicle and take pride in maintaining it. So when you went to buy a new one, you would buy the same brand. Modern vehicles are disposable appliances. Designed to meet government requirements and last until a day after the warranty expires. Then they expect you to trade it in and get a new one. They don't think about anything past the warranty. And half the time they're scrambling to make it last that long
Thing is modern cars can last a long time. People have gotten lazy. Nobody is willing to actually fix it themselves. Old cars break down a lot so you learn to to fix it. Modern cars break down so infrequently that nobody bothers the learn to fix.

One of her coworkers actually helped design the engine layout of a fort pickup truck back in like the 70s (guy is pushing 80 and refuses to comply retire) and he was told back then to intentionally make certain aspects of the layout harder so it would be more difficult for diy repairs and they would have to get it professionally serviced… this was 50 years ago THEN! I cannot imagine how much BS corporate culture is pushing that now.
This is not true. You have to consider your dealer mechanics when you design for service.
@marke8930 you mean making proprietary tools?
thats bs
@@z0mn1a Yes, and than those "special tools" can get very expensive ...
@@marke8930wow dealer mechanics. Geez, I wonder what would a low class working family with no money to afford a dealer mechanic have to do to be able to fix something dealer mechanics find difficult and/or have all the special tools they need to fix some contraption that could be easily resolved by designing it simpler 🤔🤔🤔🤔? Kinda sounds to me like repairs are hard to DIY on purpose and that money was supposed to go for the dealer they were only thinking about.
Considering your dealer mechanic making repairs vs a normal slim-to-none car knowledge person trying to DIY issues are two totally different concepts.
I can tell you exactly what happened as an automotive engineer.
Meeting 1: “we have a service issue, we need to access this fastener for our 75,000 mile service interval. Okay we can put a hole there”.
Meeting 2-30 the sheet metal team was not talked to by the engine team and the fastener was moved for some other issue.
1.5 years later they discover the problem in the second round of test vehicles. “Oh shit we already paid for the sheet metal dies and they have a 20 month lead time”
So they quickly implement a service procedure fix to get around the issue.
Guarantee you the engineer who moved the fastener told his manager. I also guarantee you that manager or the sheet metal engineering manager didn’t do their fucking job. Neither did the systems engineering manager who is supposed to be tracking this kind of stuff.
Ask me how I know.
How you know lol
Ya how
You can't tell us to ask a question and not answer it.. also, when you do answer it can you reply to this message so I can see your answer? Thanks bud... very interesting breakdown.
@@nathanstewart2168 I’ve sat in plenty of these design reviews. I had a similar issue on the rear axle of the latest GM trucks where they could not be made because someone did not think about a new process and did it the old way anyway.
These cars are designed by teams of 3-4,000 people. The left hand doesn’t know what the right hand is doing because they are not well run. It has gotten even worse now that they don’t pay people to stay and turn-over is high.
The high turnover rate is one of the worst things imaginable when running a large project that takes several years to complete.
Also an engineer.
As an engineer I can explain. The tensioner was placed. Then the hole was placed to allow for tooling. Then an issue arose later requiring a slight translation of the tensioner's location and the engineers failed to annotate the tooling hole association. These associations are fixed in a lot of model-based definition designs today by forcing an association between the CAD parts in programs like CREO. Anyway...it isn't that they hate you...they just don't think of you at all.
As a machinist who makes the stuff engineers come up with, I agree. Engineers simply are oblivious to how anything is made and draw up prints like two year olds. I can't tell you how many prints I've had to correct, guess, fix, re-make, make calls on and the engineers just sit there with their mouth hanging open. I don't understand why engineers make so much money. I do all the work.
Or the engine mounts are bad.

As a person who has studied this a ton: Don't blame the engineer, blame the suits that wanted to cut costs
I think that placing a hole in front of a screw does not cost more than placing it 3 cm higher... Stop making excuses for these guys. They are just ignorant and incompetent.
Without the suits, no one gets paid.
@@MilesFromExtraordinary of course they're necessary, I never said they weren't. My point still stands tho
It costs the EXACT SAME to change the location of a hole you were to make anyways.
@@Auroche no it doesn't lol, every change involves moving other components around. Sometimes to make it easier to access, we design a more complex system to reduce the labor time, but it requires more material, and this more cost. This often gets shut down in the favor of saving money, and the labor time gets extended because we had to take shortcuts to save material. Then the mechanics get screwed over because the insurance often only allows a certain amount of billable hours. If the insurance only covers a 5 hour repair, and it takes the Mechanic 9 hours, the mechanic only gets paid 5 hours

No, they’re not. The company doesn’t have any idea why engineers do what they do. It’s why they hired engineers; To do stuff they don’t understand. They expect engineers to improve their product gradually, but ultimately, it’s the engineers that decide how things get done.

I’ve never heard so much truth in someone’s words.
Because cars are designed by teams and teams never have perfect communication between team members.
And that is because they don't know how to actually speak or talk anymore, and forgot to send the email to the other team. In other words, all they care about is showing up to collect a paycheck like anyone with a job anywhere these days.
That tensioner was probably one guy’s entire job. The body designer was in another country and doesn’t speak the same language
actual automotive engineer here. These drive-trains are often shared amongst several vehicle programs and these tolerance issues would require retooling the drive train or chassis for each program which costs time & money. this isn't done intentionally, its a side effect of saving money.
Engineer: "almost ready, I just need to fix a few things"
manager: "just ship it we're behind schedule"
This is the reality. Everybody has their own bosses that only care about money
The real answer.
Shit comes up you have checkpoints where some dude needs to make sure you can finish a product in time, and sometimes in the crunch you bring something out that works good enough for THEM and they want to get it out NOW.
Also sometimes the timeline that they give you when you're doing your initial design isn't the timeline you're actually getting. Or it just straight up isn't enough time for the shit they want from you from the very start.
Holy Christ if i had the amount of time needed to make sure everything was correct, this sort of stuff wouldn’t be an issue. Not to mention struggling to give two rats when the pay sucks.
I want to believe this but when literally every vehicle out there has at least a few, if not several issues like this I lean towards it being intentional rather than rushing or incompetence.
With the collective decades of experience that an engineering team draws on when designing something as complex as an automobile, typically coming together over the course of several years, I have doubts that the stupid engineering choices boil down to "we were getting rushed".
Engineer: Access hole needs to be here.
Manufacturer: no problem it will be there-ish.
The engineers often identify the problem. Then the bean counters or marketing tells them stfu.
i call BS on that, engineers couldnt identify a problem if it had bells and whistles on it with a sign saying hey you dumba$$ im a problem grow a braincell and think of a way to fix me
This is the true root of the problem.
Finally someone who understands.. engineer's don't always have free Reign
That or no one communicated when a dimension changed until it was too late
Yeah because in this case it would cost so much more to put the hole slightly higher.
Two possibilities:
1. They did it on accident. Trust me, that is possible.
2. They did it on purpose to piss of mechanics "encouraging" owners to bring it into the dealers.
You be the judge.
Knowing about what things are strong and why they are strong is still helpful for guiding casual play. Calibrating expectations.
Engineers' favorite phrase "It worked in CAD."
I feel even older as we use to hear, "Well it works on paper."
Well, that’s sometimes all we have. Maybe the hole was lining up with the bolt when it was new. But engine and transmission mounts do collapse over time and things get out of line.
@@TimJaeger-lh3yh I feel you... But a good engineers usually test things. Oh I forgot, testing is expensive. And good, experienced engineers who know how things work, ask for so much money!
So the management says - why hire such guy, when we can have someone straight after studies, asking for 1/3rd of that wage? And let's give him our toughest and most complicated stuff to design. Especially when he's inexperienced - he will not whine about why this is too thin, why we can't do it this way, why we can't weld that cover over the most service requiring parts of the machine... :D

Maintenance and serviceability is purposely engineered like this to make difficult for one to repair these newer models unless the are a qualified ASE certified mechanic.
Meaning: more money is to be made for the automotive industry. What this young lad is pointing out is painfully obvious of being a shitty engineering design.

Used to work as a mechanic. Customer pays for the book time it takes to complete. If it says it takes 5 hrs then you get paid for 5 hrs even if it takes you 10

its actually just a 30 mins work,u remove the 2 14mm bolts thats holding the tensioner and the whole tensioner comes off

That's not an access hole. That is a fixture hole that is used when welding the body together at the factory. If the engineers were aware you were using it as an access hole they would figure out a way to delete it and make you remove the engine.

I completely relate to this. I’m an engineer who actually likes building & repairing things, but I firmly believe that engineers should be required to work hands-on with their own designs.
Yeup. Am an engineer in the ag industry. I do hands on with almost all of my designs.
The hard part comes when some companies have unions. Engineers can't go hands on, cause you're "taking the job" of the techs...
That's the biggest issue, not many engineers get field experience. I'm an electrical engineer at a utility and still have to get out to the field or talk to construction about things. Isn't til you get some field work that you really get the full picture
They don't let you do that anymore because it is 'too dangerous' and 'you aren't trained for it so you can't do it' like they said that my engineering team can't solder on its own anymore because we need lead solder and lead is apparently too dangerous for people with phd's to handle because they weren't specifically trained for that.
I just posted this... before I saw your post!
Yes I completely agree
3 different engineers designed the engine, support and engine mount. It's likely the position of the engine was changed late in the design after the hole location was finalized in the support. The issue wasn't caught until preproduction.The program manager justified not scraping the supports and delaying the program because "all you need to do is drop the engine". The mistake was made by a communication break down in engineering, it was made permanent by management.
I used to work for a car dealership back in OKC. As an employee i had to sit in on a few dealer meetings with corporate headquarters. These "hard to work on" designs are done intentionally at the explicit request of the dealers. The intention is to drive revenue to the dealership. Most if most all auto manufacturers do it. The dealers would complain directly to corporate in these meetings about how easy a particular car, sub assembly, or part was to replace or fix. Certain models of cars didn't get priority sales placement on the dealership lot, specifically because that particular model did not generate enough continuing or return revenue. There actually exists a book written by the auto manufacturer that estimates the amount of expected profit based on the type of vehicle, mileage and when parts are expected (engineered) to fail. I've sat in when dealers have threatened lawsuits against corporate because they weren't making enough money on repairs (cars weren't falling apart fast enough, or customers were taking them to independent mechanics to get the work done for less)...#FACT! There's a reason cars are hard to work on and it isn't because they are infinitely complex.

What probably happened is the team working on the tensioner forgot to mention to the body people they moved the tensioner slightly because they don't deal will access issues and don't have to think about it. The two teams designing this aren't at fault, it's the 3rd team of system engineers that failed to notice and by the time it was noticed, during manufacturing probably, it was too costly to change according to the accountants, so blame them as well.
Most engineering descriptions of an engine is based upon a complete disassembly, even down to constituent parts of items you don't need to take apart. It's not that the engineers hate you, it's that you don't work their way.
As someone who couldn’t do what mechanics OR engineers are capable of, I have no opinion on this matter, hope you work it out, and salute you both.
The engineers should have to show mechanics how to do it before getting paid.
Lol they literally type out the service procedures step by step with pictures so the field technicians don’t even have to pay close attention one time or remember how to do anything, except for how to read and follow directions.
Some just forget they can read over time and some live in complete denial of the service manuals existence.
When you can’t figure a repair out just ask yourself, which one are you.
And then go read some tsb’s and search for service procedure updates and check for special tools.
If after all that you are still baffled only then can you start cursing the engineers in preparation for calling tech support hotline.
I'm actually an aircraft mechanic but I've done lots of prototype work where I've had to work closely with engineers. I've asked engineers why the hole in the bulkhead that's used to remove a bolt can't just line up with the bolt rather than making the mechanics remove half the accessories, or jack the engine to get to that bolt. They just look at me like I've asked the stupidest question ever. It's a matter of respect and that's why the old engineers tend to be successful with a whole lot less effort, they listen. I get the impression that most engineers never even talk to the mechanic.

Engineers simply make mistakes due to oversight. It’s not unheard of it’s not because people can’t read it’s because it’s just a simple disconnect from the reality of having to service or maintain something they’ve designed.
An engineer can be overwhelmed with figuring out how to get everything to fit and function properly in a design so it’s only natural that sometimes quality of life for servicing is put on the back burner

For 13 years I lead an engineering team. One of my engineers made a lot of mistakes and I started to get a lot of complaints from our technicians. I took them seriously and listened to what they had to say. I asked, "how much time per week would you say you have to fix his mistakes" to which they responded, "about two to four hours and sometimes s little more". I thought about this for a bit and responded, "this engineer does three times the work of my other engineers. I don't want to ask him to slow down because he is very productive. But I will spend some time with him to improve his accuracy". I asked for a few months to improve things and the technicians agreed. The engineer did show down a little and his accuracy really improved. This engineer was one of the few who took personal responsibility for high output and kept an eye on the calendar. He was like a unicorn and I miss him.
Honestly, my theory is that it’s made much harder to prevent the layman from doing the maintenance themselves. Get people to take it to the dealership.
Exactly! And the dealership only wants to use OEM parts. Right to Repair should probably be taken more seriously.
@@leviswranglers2813 we use whatever parts the customer wants.
Even simpler answer. They don't think about maintenance. Or at least the work required for maintenance.
No, it was designed to be installed as part of the front assembly, which includes suspension and steering parts. It was designed to just slip up and be bolted into place. They never thought about anything other than time for install and saving money by using already existing parts to cut costs for higher profit margins out the door. That may not have been the initial design engineers thought as that part gets warped once production engineers get their hands on it as they have to find ways to get the same result at a cheaper price.
I disagree, never sell yourself short, you either wanna do it, or you don't, stop making excuses. Simp

@@criticaltexan2334and then focus on the wrong thing, and are paid to screw over others who will work on the product later on, thereby netting those mechanics(/whomever) a bigger paycheck due to more work done due to bad design? Is that an innocent enemy or a mischievous ally?
We're all just dumbass humans, nobody cares unless they choose to. Who would? We dont get paid enough.
Never? That may apply here but say i.e. for politicians. Those MFers are all about malice.👹
we saw that one and told the interns we didnt feel the math that day.

Never assume malice when stupidity will suffice.
Ooo love this. This solves about 99% of conspiracy theories too.
Suuure, a grease monkey vs someone who is actually educated, it's definitely not malice 🤡
@@drflannelxd904 I don't think engineers set out to create difficulty on purpose. Through thousands of design decisions things get overlooked or compromises are made due to timelines and budgets.
That said, I think there's business reasoning that repairs that require more labor and skills result in higher revenues for dealerships... So, perhaps they don't lose sleep when things like this arise?
@@drflannelxd904ok buddy
@@gunsite4575% really because at this point conspiracy theories are news in a few months. Like whenever a "conspiracy theory" about covid came out. 4-6 months later it was fact all a sudden.
Engineer definitely identified the issue in the design process. Told lead engineer of the issue. Was told to come up with a solution. They did so. Bean counter then came in and said make it even cheaper. The end
The cheaper solution is not putting an access hole in at all...
End of story, never blame an engineer unless you blame the corporation's accountants first.
People forget that cars are designed to be hard to work on
Thats what happens when you give 30 people access to a cad file and you have a huge pile of notes that you cant get through and you don't let the first shift polish the design on top of a huge time crunch, engineers didn't do anything on purpose
Bean counters run the show now. It's all arsebackwards.
Ok thats fair on an engine, but when you have to disassemble a whole door for a fuckin door handle. Only like five things in a car door, why they all gotta cover the one torx bit that needs to come off to switch the handle.
On second thought, the fact cars use torx bits is proof engineers do this shit on purpose. I have the same hex socket set, flat head, and Phillips head bits from when i started years ago, any torxbits i use regularly are max 8 months before they sheer, and the bolts strip more often.
It's immaterial that you need to replace a torx bit slightly more often if it speeds up automated mass production and leads type a more consistent torque.
Let's do it the dumbest way possible because it's easiest for you mentality. The cost of putting one straight blade screw on there just so you can have a slightly easier time is in the realm of tens of thousands of dollars minimum.
Guys, you don't understand, it's not the engineers fault, its the fact that the project manager isn't an engineer so they don't care that the car isn't done.
As a maintenance tech, i approve this message.
You pretty much got it. Budget allows for a certain amount of labor, then the head of the dept says "send the cost to maintenance" because they're only really worried about their bonus, they might not even be there next year.
As a machinist, I absolutely agree. I think engineers just hate techs and trades workers
@@lslslslslslslsl1 No one hates you.
@@lslslslslslslsl1 ya no shit right?
Hands-on experience would probably benefit many design engineers, though who knows if that's the issue here. A coworker told me about working factory maintenance in another country, where all the plant engineers were non-degreed former maintenance guys--everything was built to maintain and easy to service (this was for an internationally known beer brand). By contrast, our brand-new plant in the USA had many things difficult/impossible to reach without cutting or other absurd steps. Crazy!
It’s not to piss you off. It’s to increase the repair costs, eventually to make the customer prefer to buy a new car instead of holding onto the old one. Climate change they said… Global warming they said… Emissions they said. ..
Engineer here my man....mistakes and oversights happen (usually at later stages of design due something that's not relevant at that time). We call these lessons learned. They usually get fixed in later generations of a current model. This is why you're better of buying the last model of a given shape (usually 3 to 4 yrs in) before a complete redesigned model is introduced in the market. I promise it has nothing to do with hating you. In fact, on day one of my first job, my manager told me the best way to learn how to design something better is by watching the people that have to handel and use them. That's you.
Imagine, engineers are people too and mistakes are made everywhere. Also sometimes a multitude of unfortunate things come together to create a problem.
For every mistake you do alot of workers wanna end it all over and over again
Yeah yeah. You guys make mistakes and we're all human blah blah. Engineers don't have to deal with their own mistakes though.
Me, not listening and just making a new hole because the engineers an asshole
Mistakes are easier to track in the later stage of design, the regular occurrence is a sign of a lack of effort altogether.
My gas Samsung oven died because engineers didn’t glue a pennys worth of metal to the chipset that controls the oven.
What do ovens do? What do chips hate? The anecdotal evidence is stacking up that y’all are designing things to be thrown away. Plain and simple
"Just pissing on us without the courtesy of calling it rain"
Thats what you get when everything is built in third world countries. America doesnt make a thing anymore for themselves, do they.
The actual access hole is a bit more upwards, you need to take the engine mount off and jack the engine up to access it from above, it's pretty easy
This is a funny video, but we promise it’s not on purpose 😅 (Design Engineer here). We’re faced with the same pressures everyone faces. Management wanted it yesterday and we have a billion priorities. Mistakes happen. Also, a bunch of engineers have never worked on cars themselves. They’re great at math and design, but don’t know the troubles of maintenance… Good video. Keep calling us out (even though i’m not in auto industry) lol
Every engineer needs to work on what they make for a year!
Heck yes.
Agreed
When me and my colleagues engineered the 2020 Sentra we had to
In my company the engineer had to be on the shop floor when their design was being assembled. No hiding from their fuck ups.
As a computer engineer, I completely agree any engineer worth their salt should be able to put together and take apart the thing they design before presenting it as a possible solution ask by the company.
I think most of these kinds of things happen because it's different engineers working on different subsystems of the car at the same time and they never communicate between eachother very much. And they are engineered to be cheap and easy to assemble at the factory.
No, because when they put their schematics and blueprint’s together, they see shit like that. They know what they’re doing
@@HellcatGaminif you were banging your best friends mom and you were banging his mom aswell, would one of you find out?
@@HellcatGamin you do know there are more than 1000 people that are involved in designing, and developing cars. So no it is not intentional just managed poorly
There are actually mechanics that prove the ability to service. It's a requirement to pass this tollgate. There is a procedure you are paid to do, so use it..
I loved how Audi did this on the older models. you get your audi tool for the job, fit it on the front, and then you can take the whole front of the car and drag it out, giving you plenty of room to work on the front of the engine.
Engineers hate anyone being able to work on their own stuff.
Real simple, the engineer had a side-hustle making a socket adaptor which enables you to reach the bolt.
Having worked as a machinist for awhile, ill admit I thoroughly enjoyed being the middle-man in the war between mechanics and engineers.
Design Engineer: Dwg has it 3" higher. You need to talk to the production dept.
Production Engineer: Our line follows the quality standards, they didn't give us a noncomformance on this. Talk to them.
Quality Engineer: Yeah, everything cant be perfect. Just drill a new access, and please send me a report on this issue.
Technician: 🤬
A mechanic should never have to fix an engineers mistakes thats for sure
@@carlj7466 Nah, something like that is more project management's fault.

I wonder if a VIM half-cut Torx would be able to get it from the bottom, either with a low-profile ratchet or by using a pair of vise grips to turn the bit. I've gotten into some really tight spots with mine, and wouldn't want to be without them.
I used to be a mechanic but I got in a car accident a few years ago that wrecked my back. To be honest things like this really makes me not miss the job now the only car I will get a work on is my S 2000 and unfortunately the stupid AC just went out, that’s not the kind of work I enjoy
I got an answer for that! In one of the revisions, the bolt was lined up with the access hole. One thing lead to another, and they had to move the tensioner bolt, but forgot to move the access hole before the plans got approved and sent off for production. This happens a lot when you run into unexpected issues and have deadlines to meet.
What an awful way to design cars
@@UN4SS1GN3Dnot really. It’s extremely unrealistic to have to do a redesign and then recheck every single part and potential access port affected before resending. It’s still a shitty mistake to make, but that’s how iterative designing works
@@UN4SS1GN3DCorrect.
@@UN4SS1GN3D Management says we're spending too many hours on design rework.
Welcome to capitalism and its shareholders requiring their short-term quarterly profits at any cost, and thus forcing the workers of the companies they're investing in to work quickly and release even quicklier, disregarding any issues that don't directly lead to major failure.
I honestly think these companies are doing it on purpose the same way they're purposefully doing it with technology, phones in particular, with the idea being the harder they make it to fix your own stuff, the more likely you are to pay them to fix it for you like at a dealership.
In a few years, you won't be able to change brakes! Some buick/chevy crossovers if you disconnect the battery.. the dealer has to flash the memory! $$$$$$$$$
I’ve been repairing phones for about 10 years. It’s way easier now than 10 years ago, and parts are easier to get. Heck, now you can even find a high res video explaining how to replace surface mounted components.
The goal is to get you to buy a new one
The corporation doesn't care if its serviced at the dealership. They only care that their proprietary parts and software get used.
See my reply, nah this stuff is incompetence.
This probaply there for the timing chain replacement, often where i work we do tensioner and pulleys to, and since we have to
Drop the engine down. Pretty obvious but i rather make it loose earlier to
It's a cold world, but I don't believe the car makers could care less. They don't pay for a costly repair years down the road, paid for by the consumer. They only care about selling the vehicle and making money. I'm a mechanic and that's the conclusion I've come to after many years of wrenching.
I understand the frustration...usually there's a few cuss words and a busted knuckle before I just drill another hole and then ask myself why the hell didn't I do that to begin with.
As an engineer: Don't just drill holes into the body of a car... We do a lot of computer modeling to end up at the exact shape a car body is... Drilling random holes into a cars messes with that a lot. :(
@@RoonMianWell then put the damn access hole in the right place and we won't have to.
@@RoonMian So you being an engineer, answer me this then. Why is is that you people make shit so hard to work on without special tools or having to pay someone a ridiculous amount of money to fix a problem that would otherwise be an easy fix.
@@jeramypompabecause they want you to have to pay someone big money to fix it.
@@jeramypompa
You figure it out. They don't want you fixing it. They want you to go broke, paying a dealer shop and/or buying an overpriced one time tool, and/or buy a brand new even bigger piece of junk. Planned obsolescence.
My dad was a mechanic, and his theory was money. He figured they make it hard for the average person to do it so that you end up taking it to the dealership so they can charge insane rates to work on it.
Exactly. That's what John Deere does, too.
Sounds more like the businessmen telling engineers what to do to make life hard for mechanics
This used to be true. The video however demonstrates a perfect example of the disconnect between the engineer/designer and the person that reads the drawings and makes the cuts or produces the part. This routinely happens in construction all the time between the architect and the actual builders. The builders are typically the ones that read something wrong they caught the mistake too late to fix it so they had to come up with some weird fix that stands out lol.
Mechanics used to be mechanical engineers, now they are just part changers. They change parts that suffered resulting damage, but fail to correctly diagnose the cause of failure, thus not correcting or truly repairing the problem.
I was woking on design of locking system on some van. It shared the ground wire for locking motor and locking sensor, and used the same wireing form a car. It being a van, it had more powerful locking motors, so higher current caused locking sensors to glitch, sometimes. But we were notmallowed to chage the wireing. So we had to engineer our way around the problem by ignoring sensor signal for 1s.
I hated my job so much.
It’s not the engineers that hate you. It’s the accountants who don’t give a sh!+ about you.
Just remember engineers, Anything worth doing is doing right the first time.
@@schreadersautorepairllc.6202Unless you're planning to pay the engineers salary, that's not how it works. Engineers will always design parts the way the company wants us to design them, not the way we'd like to. I've argued my case when it's something egregious, but I don't have the time to fight about every single part that I design.
This is why I like working on older cars. They were designed with maintenance and repairs in mind. They wanted you to enjoy your vehicle and take pride in maintaining it. So when you went to buy a new one, you would buy the same brand.
Modern vehicles are disposable appliances. Designed to meet government requirements and last until a day after the warranty expires. Then they expect you to trade it in and get a new one. They don't think about anything past the warranty. And half the time they're scrambling to make it last that long
Thing is modern cars can last a long time. People have gotten lazy. Nobody is willing to actually fix it themselves. Old cars break down a lot so you learn to to fix it. Modern cars break down so infrequently that nobody bothers the learn to fix.
