Every week I teardown at least one failed, blown, or bad engine on this channel. Here are some of my past favorites:

Today we tear down a 2.0L Nu G4NC Engine from a 2018 Hyundai Tucson. This GDI 4 cylinder produces about 164hp and is used in MANY Hyundai and Kia vehicles, and is also included in the class-action engine failure lawsuit which is currently ongoing. Apparently, this engine missed coverage for this and died at just 91K Miles. The carfax history shows relatively solid maintenance history and combined with such low miles, if you didn't know the history of these engines you'd think this was abuse.
Why do these engines fail? Why do they always fail the same way? What can be done to prevent it? Lets tear this one down and try to answer these questions.
Why am I doing this? My name is Eric and I own and run a full service auto recycling business called Importapart. Part of our model includes dismantling blown up, bad and core engines to salvage the good parts. We do not rebuild or repair engines, merely supply parts to those who do.
I really hope you enjoyed this teardown as always I love all of the comments, feedback and even the criticism. Catch you on the next one!

@@HarryTwatter Unless you don't go in for some useless "recall".
And good luck with getting them to honor the warranty...
The 10-year warranty only applies to the original owner.
When our 2.0 blew, we had to many different dealers to find one that would fix it. They are all told not to mention recall, then if the owner knows, deny the replacement for “extreme negligence”. So sad to go through that, but replaced in the end
Great way to foster customer loyalty! 🤣🤣
Good grief. Deviousness and obfuscation. Just goes to show the company is now trying to stop financial losses through needing to replace so many damn engines.
@@MattExzy Strange, my mom had the exact opposite experience. Our local Hyundai dealership took the car in no questions asked, and gave her a loaner the entire duration of the 4 (!!!) months it took to get a new engine.
@@mattt198654321 took way too long to get the engine and now they are trying to deny claims. Both bad.
Thats really sad you had to go through that my Hyundai dealership will gladly replace them and Hyundai never questions anything on the NU 2.0 in the Tucson. As long as it has had OK oil changes. We make so much money replacing them we are always willing to do it
I'm a Hyundai tech. Usually what we see is the #2 or #3 rod bearing essentially eating itself. Hyundai even has a machine specifically for testing for this issue without any major engine disassembly. Also, if you want to have some fun pull the exhaust CVVT sprocket off the cam and see if that little pin is wearing a bigger hole in it. That's another common failure point on these motors.
Looked like #3 rod was worn thinner
Job Security. I work on Harleys for the same reason.
Piles of those pieces of junk here awaiting core pickup. Absolutely garbage.
So when Hyundai DOES replace these under warranty - is it just the same flawed engine going in? Was there any design mod made to improve the issue, or is the idea that a new engine will get you another 80-100k miles before it fails again?
The first generation Theta 2.0L 4-banger was a paragon of smooth and reliable power: I still love my '11 i30/"Elantra Touring", though I'd like to fit a 6-speed manual to it.
I very quickly learned, when it comes to Theta II: AVOID!
Legend has it... That wristpin is *still* trying to hitchhike it's way back to Korea!
yeah in north Korea. There could be a theory that KIA and Hyundai have engines made from North Korea.
errrr, im sure this was made in Alabama :)
It must miss it's mother dearly. . 🤥🤣
@@WilliamHollinger2019 Next time you have a thought... let it go.
Wow, that was a WILD impact mark he showed at the end! That thing must have TRAVELED! I wonder if some other person has a small 'oval' hole in a window on their car and this pristine wrist pin hanging out on their passenger's side floorboard or something. If it was in a drive-thru when this happened, anyway. Or something like that but on the windshield if it happened on the highway.
So if the Kia boys don’t steal your car, and it doesn’t randomly burst into flames, your engine will implode. Haha
😂 Built In obsolescence
And everyone that knows nothing about cars keep telling us they are just as good as Toyota and Honda... We know better, Kia and Hyundai are by far the worst!
@@mondocjenson-dy8zdBuilt-in is hyphenated. Use Grammarly, or try school.
My next door neighbor is an engine warranty engineer directly employed by Ford, but he regularly talks to his counterparts. He says these are what they call 'in cylinder episodes'. Not bearings, not oiling. It appears the pistons are not quite up to the task. They crack, take out the cylinder head, spark plug and valves, the cylinder overheats and cooks itself and the rod and the whole assembly comes apart. Pistons 2 and 3 mainly. When accountants get hold of a car design and shave pennies off the manufacturing cost. It was ever thus.
With those caked up rings on a direct injection, I could believe there is LSPI happening and there is not enough meat in pistons to endure that extra pressure, and they slowly crack apart.
LSPI - Low-Speed Pre-Ignition (for those wondering and too lazy to google). What I don’t understand is how engine oil can help? The Wikipedia article on LSPI seems to make a link to this but lacks details as to why.
@@jeremyloveslinux if I had to guess, the water weight oil that is getting past the thin low tension rings is heating up enough to vaporize and detonate in the absence of fuel vapor to cool the intake charge/compression stroke on DI engines. Diesels run heavier oil and thicker rings and pistons to deal with the high compression, so they would have less of an issue than tiny gas engines worked beyond their reasonable limits.
It was in the CNC programming. The guy who wrote the CNC program to machine the engine blocks, forgot to put in a rinse command after one of the machining points. Since the machined material wasn’t rinsed out, it got pumped into the rod bearing. It’s not a design or material flaw, it’s human error.
@@paulnunya3429feels like that would take out an engine relatively rapidly, like within a few hundred miles

What i enjoy about this channel - aside from Eric's humor - is how each manufacturer engineers their motors. For example, the US majors vs the Germans, Japanese or Koreans. I'd love to see somebody donate an Indycar or F1 engine. That would be a trip.
Omg a blown to hell and back race engine...we would worship the ground Eric walks on 😂
Motorcycle engine teardowns would be cool to see as well. The two i've seen personally were from a leaky fuel injector diluting the oil and seizing the crank bearings, and another had an oil pickup completely clogged with clutch material that also seized the crank bearings. Both were inline four sportbike engines.
"Why number 3"... might be the clue to the whole shebang there, and I'm noticing that it's the first throw on the drive side of the crankshaft from the thrust bearing. It would be the first to suffer from flexing or harmonics if something like converter ballooning or a missed converter stab depth was happening. Basically you push on the back of the crankshaft and the #3 journal is the least supported mechanical member between that force and it's limiter, the thrust bearing. Pause at 30:50, look at the left edges of those rear two main bearings, they're more polished than the rest.
If this is the problem that may be why Hyundai/Kia is having such a hard time with it... the tolerances closing up from crank flex would only happen with the engine running and providing torque to the transmission. Take it out and open it up, and barring wear the bearings clearances would be just as intended. Give it a hard rip, crank gets squeezed from the back, #3 rod journal flexes a little teeny bit, bearing clearance hits near zero for a small portion, and now it's compromised and a ticking time bomb waiting to wear the rest of the way and spin.
That is a really good theory. I think you might be onto something here.
Interesting. If you got to figure this out,then pretty sure Hyundai / Kia knew it already and know that they can't do anything about it as it is a design issue. The thing is, they still continued to sell this engines knowing too well it is just waiting to happen. Heads rolled probably at the engineering department and the ones left were just juniors who inherited the problem.
@@chronicle_4agreed!
I wonder if the manual trans cars (there were some) have blowup issues? And note many countries still favor the manual transmission (this being a world engine).
Great theory, but in this case I think you are not right. If the bearing failed before the piston there would be glitter all over the engine and all other surfaces would show bearing material being pushed through in the oil. The rod would show heat damage and would have been broken. In this case it is obvious that the rod bearing was doing fine until the wrist pin got stuck between the block and rod, bending the rod out of shape. Once that happened the bearings had no chance but the driver clearly stopped more or less immediately after the piston failed and engine power and noise levels made them aware of it. I am not saying that your theory isn't a failure mode that these engines suffer from, but I think it is more likely that bad knock control that somehow effects cylinder 3 more (resonance/vibrations in the engine casing or bad location of the knock sensor(s) makes cyl3 less protected by the knock protection system and ignition retard is done per cylinder, making cylinder 3 the one to often fail first. Whether it's the piston cracking or rod bearing giving up first in my theory is not really relevant, both cases are catastrophical. The root cause of knock is probably the bad oil scrape ring design causing excessive oil in the combustion chambers.
I had one of these do the same thing on the highway and deleted 2 pistons. Only 62k miles. Great engines!!
No-one gets it - these engines are so great that they actually can't contain their greatness and they explode. Now THAT'S great.
Love it 😂
Great at...
I bought a 2015 Sonata 2.0T as a leftover in early 2016. I put 100K on it in 5 years. But I also maintain my vehicles much differently than anyone else. Just like every new vehicle I purchased, it got its first oil change at 1000 and second at 3500 miles with 5W30 synthetic. From there on it was zero w40 every 5K. was totaled by my insurance company at 100K for floor pan damage and losing at most half a cup of oil between 5K services. If I could post the picture of the inside of the engine, I would. I took a picture of the top end when they were replacing the valve cover gasket at 80K. It was immaculate. Just like you said Eric. I know people who had multiple engine replacements before 100k, and I know others who are well over 200, even 300k, on their original engines.
I have a 2011 Sonata 2.0 turbo and maintain it similar to your specs. The motor lunched itself at 185,000 KM (115.000 miles or so) The dealer replaced it under a special warranty extension and I've put another 100,000 KMs on the replacement. Hoping to get a few more years out of it. Edit: dealer was easy to deal with and I got a free rental for the repair time. Surrey BC Canada.
Why do I sense Eric has a trophy room full of timing chains?
He could gold-plate them and every brutha would want one.
I think he has a secret timing chain fetish. Go watch ANY of his videos and watch how he handles them, and pay attention to what he says.
its more like a sex dungeon then a trophy room
He does have a deep love of chains... But at least he always starts at the front
I sure would like to know what happens to those ... 😏
I've had my Elantra with a NU engine for 13 years and 73,000 miles. Every time I see a video like this I break out in a cold sweat.
Keep up with your oil changes and keep the receipts.
If yours is a 1.8 NU its not a GDI engine they are pretty decent little motors keep up on oil changes every 3,750-4,000 miles keeping receipts won’t help since its not under the recalls
HUH, was yours built in the USA? I suspect this might be a contributing factor. Every complaint about Hyundai/Kia seems to be from US customers. In Australia i dont seem to see or hear of any problems like this, but ours are not US built,
@@adoreslaurel Mine was built in Korea and so far it has been 100% reliable.
@@JoeMama827 Our little Getz had only 89000 Kms, but has been good to date. Korean built.
Had one of these. Bought it brand new and it never saw the dealer again for the 9 years I had it.
Put just over 300,000km (180,000miles) on it without an issue.
Didn't get much for it on trade, but it never let me down.
One of the lucky ones I guess.
2016 Kia Sorento 2.0 L turbo. 55kmiles. All oil changes done at dealer. I checked the oil level every 2 weeks. 2 years ago, oil level fell from full to dry dipstick between checks. No oil on driveway nor garage floor. Took to dealer and got the stink eye from them. Got another brand of vehicle.
What did you get?
That's the low tension rings. Especially bad on the turbo models. We've got a TSB for that now.
@@1337penguinman Apparently the new Volvos are having oil consumption problems because of the thin/low tension rings they're installing.
@@jnordne2 haven't heard the newer Volvos having consumption issues. Mid 2010's 5 cylinders definitely had a problem however.
Thank the EPA
Back-to-back teardowns? We aren’t worthy!
We are so not worthy
At my former job we had two different Kia Sorento's that had bad engines, the first one had 140ish thousand miles, but since it was used for commercial service they refused to cover the engine replacement, second one had 110ish thousand miles and was running rough, they determined the bearing tolerance was beyond spec and swapped it under warranty. The service tech said they were replacing about 40 engines a month and that was about half the number of cars coming in with dead engines. Not a vehicle you want to own past the warranty period.
It's slowed down some. I'm currently averaging about 1 every week or 2. Thankfully they're actually really easy to pull, but you still get screwed on the warranty times.
strange it is US problem. europe made engines in hyundai cars are bulletproof compared to this. even 1 liter 3 cilinders hold up decent

They should put Apple tags in all the wrist pins so you can retrieve them later from the interstate
Almost funny, nice try though.
Thanks for the Saturday night carnage, I always appreciate that. When #3 blew, it didn't run for long---if it did, you'd see torn-up bearings and blued rod caps and mains. We can't put this one on owner negligence, this has pure factory defect written all over it
Eric, for Halloween, you need to wear all the timing chains you have collected and call yourself Mr T. T as in Timing.
“I pity da fool!”
😂😂😂😂😂😂😂😂😂😂
They can change the logos and make them as pretty as they want but at the end of the day, its still a PoS Kia.
I gotta say, their engines can stack rod bearings better than any other brand in their respective class.
I love that YT showed a Hyundai ad before this video!
Uploads twice in a week? Two days in a row? God bless you dude. Keep up the good work
That recall is just a convenient way for them to deny a future motor replacement claim. Basically if you don’t have that recall done then your engine won’t have an extended warranty on the engine. Most people are not aware of that small yet crucial detail.
True, but the recall means the registered owner received in the mail a letter from NHTSA with the label IMPORTANT SAFETY RECALL. This does raise the question however, why doesn't the engine already attempt to save itself from knock, without the software update? People ignore flashing check-engine lights nowadays despite being told "stop engine now" when that happens. Engines have to be designed for a driver who is a complete moron. It appears these engines may have missed that mark lol.
@@jimbo5728Today's engines show the check engine way too sensitive! Also when it goes on off. Just show the problem on that 10 inch screen you have on that car. Not the "contact service", "contact service, knock sensor sensing blabla, engine damage imminent" is the right way!
My family's '16 Sante Fe Sport went pop at about 65k during a vacation road trip. I have an interesting tidbit of information that might help inform the theorycrafting:
My dad had his foot down to pass someone on the highway - the third time that trip - at the moment it started making horrifying noises.
Unlike a lot of people who own these, he immediately pulled off and checked fluids and everyhing (oil level fine).
When he saw no obvious problems, he went another mile, then pulled off and called a tow when the terrible noises persisted. They honored the warranty.
So I personally think that's a major reason why some engines last while others don't: Whether or not the owner is pushing them too hard.
inb4 Yes, I know, a correctly designed engine should not delete a bearing just because you pushed the tach past 3500.
Bonus fun fact for reading this far: My stepmom blamed my dad for blowing it up.
Woman: gotta love em!😂
I think your stepmom was right! 🤣
Traded in my '20 Optima 2.4 for a '24 Corolla 2.0 and couldn't be more delighted. Big mistake corrected with the right choice.
Can't go wrong with a new Toyota! I just purchased a 24' Toyota Camry, great cars. I hope to drive it for the rest of my life. I wanted to get the last naturally aspirated Camry, did not want to worry about the hybrid system 18 years down the road.
@@donniev8181 yeah except the stop sale on the trucks because their engines are blowing up...
@HarryTwatter everyone on earth recognizes Toyota as the most reliable auto manufacturer, everyone except butthurt Honda fanboys that is.
@@donniev8181I get what your point is here and Toyota indeed has a great rep for reliability but the reality is their NEW TTV6 in the tundra is having issues. For context I’m the kinda guy who recommends buying a Toyota if you don’t know what you want but you want it to be reliable. Sometimes new designs have engineering OR manufacturing issues.
@@ivancliff2514 again, your comment has absolutely nothing to do with our conversation!
The Safety Tote make a triumphant return 🎉 🎉🎉
We blew two high pressure fuel pumps before the engine gave up the ghost. It took Kia only 6 days to get it replaced which is 5 months faster than when it ate a valve and turbo.
After that piston imploded, the wrist pin saw an opportunity and made a break for it. That inspection port is actually an ejection port and that wrist pin came out of there like a .50BMG casing from an M2 Browning.
My wife's 18 Kia Soul 2.0L had a bearing failure at 85 miles past 70k. It presented as low oil pressure and a misfire but no check engine light. Russ Darrow Kia of Waukesha diagnosed it as a bad exhaust cam phaser, I later found out they based their diagnosis purely on having a cam correlation code and readings from the cam position. After they did the work and took it for a test drive it still had "drivability issues." They then did a software test that showed the bearings were bad but they still wanted to charge me for the top end work they had done, on engine that was now condemned. After a month of arguing with the service department I literally had to make a scene in the dealer's lobby to get them to set things right. I found out from my dad who knows a local Kia rep that this particular dealership is really bad about warranty claims. Thanks for this tear down. I'm sure it will come in handy when I am out of warranty.
Oh they also tried to argue after the fact that my timing chain was loose because it had stretched. No you idiots, it's loose because there isn't enough oil pressure to tension it! God those service advisors pissed me off.
A Friday night and Saturday night tear down?! Heck yea

Good explanation for the what and why regarding the KSDS update which enables the extended engine warranty eligibility. No matter how many times I've explained it, there's always someone who says "I got the update, why did my engine break?" Because the update was never meant to "fix" anything but rather decrease the likelihood that you'll be able to drive it until the wrist pins are the only survivors. Still see a few seized, but it became far less common after the update.
Sounds more like a fake hurdle thrown down in front of owners in order to deny repairs . Looks like they are learning from Toyota. Ha.
Well done Eric, for over 3 years now you’ve made my Saturday night ritual of watching I Do Cars before bed entertaining and I want to say thank you
The factory maintenance schedule on these (per Alldata) is every 3500 miles. I think they have figured out that 5k is too far
So this is how they make three cylinder engines.
My buddy who worked at a Hyundai dealership years back said he built towers behind the shop with all the blown theta engines had had accumulated over a few months
Sure he did
We rented a Tuscon in Albuquerque a bit ago and while it didn't strand us and it admittedly was a comfortable vehicle, the drivetrain didn't feel well sorted. The transmission was constantly hunting up and down even on flat highway sections and it was looking for power it didn't have... But solid looking and very functional, just wouldn't keep it over 50k miles...
I am Tom from Tucson. Note the spelling.
Their easy thefts made me get rid of both our Kia and Hyundai for 2 RDXs.
Hyundai replaced my 2.4 when it failed at 190,000 km. It had all the updates and had no issues until around 185,000 km it went in limp mode. It was checked and passed until the final fail where limp mode turned into tow truck. I'm happy with the new engine. It's a lot better on fuel than the old one.
What I have seen about the Kia engine replacement program applies to 2010-2015 model years, and is because of improper machining and cleaning of the crankshafts during manufacturing. That engine is a 2018, and rod bearings don't normally grenade a piston. I have also heard of GDI detonation when not us API SP grade oil. That piston looks suspiciously like that is what happened, and would be just cause to dny warranty.
I knew a guy that actually bought a used water pump at a junk yard for $5 then bought a new gasket for $5 it was for a sbc at the time you could by a new water pump and gasket for $15.
When you factor the time it took to get to the yard, that's a winning strategy right there. If you make $1/hr...
At 4:50
"....the third first thing I want to do..."
Yeah, he said that!! Now, back to a regularly scheduled video....
A buddy of mine works for Hyundai and his girlfriend is on her second engine. He said it's a known defect but they really don't have a permanent fix; the corporate office is just hoping their next design is reliable.
I seriously just went through this woth my 2012 sonata. P1326 is the death code. Bearing clearance. Better keep that oul changed because is not, they WILL NOT cover the engine replacement. I got lucky even though i bought mine 2nd hand. Had every oil chamged logged and got a new motor.
Keep the oil changed every 3,500 miles with a factory filter sounds dumb but I swear it works we have 5 of the 11-13 cars in my family the ones using aftermarket filters have all had engines before 150k the 2 that use factory filters and Valvoline/Mobil 1 full synthetic both have over 200k on original motors and dont even use oil. Did find the Valvoline Restore and Protect helped oil consumption greatly on one of the replacement motors that Hyundai didn’t cover being a rebuilt title.
@@Austin-cg7be i read online a few places to use only factory oil filters on my '07 santa fe 2.7. after 500 miles on an oil change with a quality aftermarket filter developed valve noise, not bad but concerning, swapped in a hyundai filter and slowly went away!
@@ScottUnangst yep !! I almost blew up my Genesis Coupe using an aftermarket QUALITY filter used Mobil 1 and K&N aftermarket and always thought it was going to let go put a factory one on and it quieted right down
That was some serious chain guide air time!!😂
Thank you for the real reason that people install engine inspection ports!
My wife has a Tucson and we got the engine re-flash done. Our local dealer seems pretty straight - the guy told me if the engine fails after this, they just replace it under warranty, no questions asked. Then he pointed at the shop and said 'That's what half those guys are doing right now.' Too bad it's such a bad design, as it's otherwise a good vehicle.
I love the chain rails. I laughed big time.
I had a feeling there was a reason for leaving the water pump for last, and you didn't disappoint Eric!!!
Thank you.
His comedy bits are gold 😂
My son's 2017 Sonata is on its 3rd 2.0t. The first developed a knock and the dealer was quick to replace it under the lawsuit. The second engine began misfiring at about 4500 miles so I replaced the plugs. The misfire seemed to go away but I scheduled a trip to the dealer anyway and they said the car was good to drive until then. I decided not to drive it at all until the appointment. Well, I went on a test drive and didn't make it 5 miles before one of those holes opened up on the front of the block in cylinder 4. The dealer completely tore down the engine to satisfy Hyundai and got us another free engine. They also gave us a rental while we waited 3 months. The final bill, which we didn't have to pay, was over $10,000. That's more than the value of the car right now. The dealer = 10/10. Hyundai = 1/10.
My late sister had a Rondo with this engine. 80k miles, the #3 cylinder was trashed. Not to the point of having inspection ports in the block but it certainly had rod knock. Odd thing the mechanic showed me is that if you took the plug wire off that cylinder it got quieter. Dealer refused the warranty claim because she couldn’t prove that the oil was changed every 3000 miles BY THE DEALERSHIP. And finding a good used replacement engine at a price that made sense was impossible. Oh the wrecking yards had no shortage of vehicles that used that engine but they all had bad engines that Kia wouldn’t warranty. The Rondo, in beautiful condition other than the engine ended up making a one way trip to the junkyard. Almost every wrecking yard you find, if you find a nice looking Kia it probably has a bad engine and it’s probably one of these engines. Put this on the legendary engines list with other goodies, like the Chrysler 2.7 V6 or the Ford EcoSport 1 litre 3 cylinder… or even the Vega (remember those?)
Vega or monza- Jumper the fuel pump switch on the engine,add oil every 2 days....no smoke at all.
Mr T would be proud of that chain!!
This is not a new problem. I have been an auto repair tech for 27 years. In 1997 Dodge Dakota's with the antique 318 were the subject of a recall to flash the ECM because the EPA caught Dodge rolling these out with a different flash than they tested. 2 things became clear very quickly: 1; The recall flash was causing trucks to come in on the hook left and right with a hole burned in the #1 cylinder. 2; Don't flash someones truck with the recall file. I'm not saying I broke any laws or stole money for work I didn't do but I am saying I wrote down that I reflashed a PCM when I didn't. And we had a DRB3, the factory scan tool at the time, that still had a copy of the factory production ECM file and every truck that was in the scope, that I worked on, was checked and had this file installed. I want to change your belts and coolant hoses, I do not want to replace your engine. From personal knowledge I am aware of many other manufacturers having problems with otherwise reliable engines due to chasing for that last 0.10% MPG. Every time I see a Hybrid with cheap non low rolling resistance tires I just want to scream. So much dumb stuff is going on to turn a 33mpg car into a 34mpg car. And- almost 50 years ago a Datsun B210 got 50mpg.
That's before fuel had vegetable oil in it
Wasn't that Datsun a Cricket?
Ahh the sound of head bolts coming off. Satisfaction in sound wave form.
I was an auto insurance adjuster. These problems are so common. But my brother has a Kia Optima right at 200K miles and it still runs.
The Elantra uses the port injected version of that engine which is not included in the warranty extension. So instead of what you see here, the main thing they do (and usually a bit past 100k miles) is have the pin between the exhaust camshaft and its phaser shear off. That results in a timing code (adjustments become impossible) and is very much repairable if not ignored too long.
Breakfast of champions, Hammer Forged Piston Chunks.
That wristpin got drop kicked through the block by the crank counterweight as soon as it fell out of the rod. Thanks for the teardown.
Someday I think you should do a teardown with only a cutting torch. LOL (Probably want to be outside though). 😊 Thanks for the video!

That's unfortunate, no coverage for a known issue, b/c it had the factory tune. Seems crazy that they can deny coverage, when the alledged fix won't save the engine.
As a non-engine person I love it when you point out little details or trivia about specific parts. Learning stuff!
We have this engine in my late wifes 2019 Kia Soul which she purchased new. It has 46K miles and I have avoided bringing it to the dealer due to all the horror stories Ive read about how the 'reflash' causes the engine to run bad, stall, etc and people have to have their vehicles towed back to the dealer. I drive the car very gently and try to never exceed 2500-2700 RPM. It gets 30+ MPG. I had been changing the oil and filter every 6000 miles (owner manual spec is 7500) but the last one was at 5000 miles which I will maintain doing.
Between how easy it is to steal them and how bad their engines are I don't know why anyone would buy a Hyundai or Kia
They don't know.
Sounds like a Hardy Boys book. "The Case of the Disappearing Wrist Pin."
Oh, Eric. I love your moments of goofiness. The chain guides bit was one of the best, so far. On the flip side, I’ve also learned quite a bit about engines.
Sadly, a neighbor of mine had her car go up in flames in the property drive way. I had to call 911 to "increase their response time". When it became too dangerous, I encouraged her to get away from it because the fumes were toxic. We both had to watch her KIA go up in flames. Fire Department showed up about 5 minutes too late.
The problem I have with these engines is that it is a known fact of a defect. There are dealers with back orders for replacement engines. The people most affected are not rich people. These are folks living check to check relying on a vehicle that takes them everywhere.
I have never thought of Koreans as great engineers or engineers at all. The body shop i work at is behind the local Hyundai dealership. I see them moving crate engines into the garage to replace yet another blown engine. I personally would never own a Korean vehicle, they copy, to the best of their ability, what other manufacturers make I guess because they aren't capable of designing/engineering their own vehicles. A Hyundai salesman told me that. I own a 2016 Mazda 3 i Grand Touring with 145,000 miles and its just like a brand new car, but then Mazda has some incredible engineers and designers. My boss has a 2015 Santa Fe with the 2.0 L engine, 62,000 miles and one cylinder, im guessing number 3 is hammering like crazy. When it comes to Hyundai/Kia, I don't roll cheap like that.
Great video, ive been waiting for a Korean engine teardown because I know about their high failure rate.
Nationality has nothing to do with it. It's a question of what the bosses at the very top prioritize. They're not into innovation or quiality, but cheaply replicating what others do & selling so many that they can easily absorb recall/warranty costs.
There Anti-Apple smartphones also disappoint. I don't buy Korean.
My 2014 Kia Soul had the 2.0 motor, I bought it for my daughter unaware that engine is problematic… she was 18 and running active miles, enjoying the car until a month later the engine blew with 51,000 miles on it. After a month of back and forth with dealership and angry threat of litigation, Kia replaced with a new engine under the recall.
I have to give negative feedback to Kia for that whole process… it took a month AFTER the first month before Kia would get the car into the shop for replacement.
Next up, a month after getting the car back the panoramic roof track failed. That is a bodyshop repair that also took forever to get done.
My question is, did they just replace the bad engine with a new version of the same engine? Isn't it likely to just fail before 100k miles again?
How does an engine "blow?" In decades of experience, I have never seen it "blow" or "explode." Metal isn't an explosive.
We have 2 hyundai i30 and i40 turbo diesels.. super reliable and great performance.keep changing that oil every 3 months with full synthetic regardless.
I have a 2016 i30 crdi. Done 310,000. Original engine - never had an issue and it runs like new. Change oil every 15,000. Incredible car.
Dude, your timing chain guides antics are starting to rival your water pump antics for how hard they make me laugh😂
We had a Ford Exploder which has the talent of making the spark plug in cylinder #3 go short from the electrode to the shell within 500 miles. I kept a box of plugs on hand to change plug #3 whenever I got a misfire code.
Change coil 3-2 etc.
The V6 3.3L also is trash. Wife had a 2017 Santa Fe and it ate all the oil and left us on side the road on my birthday. It was at 97k miles so still under warranty. 5 months later we got a new small block. She had the car two days and got in a multi car crash (wasnt her fault). She now has a 4 runner.
Wives. Always destroying the good cars.
My wife (who was my fiancee at the time) destroyed my 1995 Escort in rush hour traffic. Got rear ended and pushed into the 2 cars in front of her.
Not her fault, but damn it! I lost a good car! (She was fine. Got out beating her chest like a gorilla 😁)
@@sdrape4964 same thing happened to my wife, but it was on a high bridge by our house.
Seriously lol! I have a 2011 lacrosse in amazing condition (I take extremely good care of it) with the 3.6 (306 hp) and my gf isn't allowed to even touch it. When her Subaru went, I told her she was Ubering to work cuz I know as soon as she touches my car something will happen 😂
@@LucasLeCompteMusic You lost a Ford Escort too?!
@@sdrape4964 lol no a Santa Fe.
Well I went and bought myself an LH2 version Northstar engine a couple weeks ago and got it all torn down, and I've gotta say, for only costing me $480. dollars grand total and "supposedly" having 157k miles, it's really nice looking inside. And it came with EVERYTHING on it and with it, computer, under hood wiring harness, manifolds, motor mounts, all the accessories, throttle body, flexplate and torque tube coupler, starter,,, everything.
It was definitely a score....
Just gotta get her built up for some BOOST now!!!
True to form, Hyundai/Kia never disappoints by supplying "block inspection ports" at NO CHARGE! GO HYUNDAI/KIA!!!!
Hyundai tech here, engine was most likely denied warranty coverage dude to the the engine ecu not being updated
Yeah. Bearing gave out and they probably kept driving on it until the piston deleted itself.
What's that do. Detune the engine from the power originally paid for?
@@ChristdelivermeIt basically puts the engine into limp mode if the knock sensor picks up a certain level of knocking.
@@sharkinstxSo the vehicle goes into limp mode randomly while driving, you take it in, they still deny warranty.
The wrist pin must have ran off to join the circus.
This is pretty much the only channel left I watch on standard speed. Thanks!
Not sure how my "engine" fits in with all these comments, mine is a 2010 Hyundai 2.4 Sonata with 160K miles, 110K when I bought it. I've had it 5 years. In 2022 I changed the antifreeze, it was the cleanest antifreeze I've ever drained out of any vehicle, and I'm 70. I change the oil every 5K miles, so about twice a year, and have never had to add oil between changes. The car will go 130 and 135 if I have enough road. I test that every month and I get about 30 mpg, more on a trip. I've replaced the starter one time, didn't have to craw under the car to do it. I'm still on my 2nd set of silicone wipers, and the 16 inch tires seem to last forever. I paid $3k while used cars were still cheap and other than replacing a couple $10 door handles, the only other maintenance item is the brakes. Already bought the parts, so all in outside of gas and oil this car has cost me .085 cents per mile to drive, oh my liability insurance is around $200 per year. That would raise my cost per mile to .104 or ten point 4 cents per mile. This is probably the cheapest car that I like, that I've ever owned.
Try to keep the rpm below 2700 as much as you can to greatly lower the probability of a piston failure blowing up the engine...in usual driving seldom should it be necessary to rev up higher than that...
Mines been fine so far after ten years and 100K I change the oil more often than the recommendation though
On my Kia 3750 miles is the severe service interval. And apparently the act of firing the thing off constitutes severe duty.
@@502Chevy😂
I hope the scrap value is more than it cost you. Hyundai and Kia are pure junk. 2 teardowns in 2 days! BONUS! Thanks Eric.
What a shame. My little 2.0 in the 2000 elantra is probably still running for someone. I changed the timing belt twice and sold it for 100 bucks at 200k miles. I loved that little engine. I saw it on the road about a year after I sold it.
“It will be just fine” is a line I have caught myself using sooo many times since watching this channel!
Whenever I remove a tensioner now - I put a 5 gallon bucket on my head and yell loud enough for the whole shop to hear - "Remember to Bucket Up for Safety! Bucket up!" (if you're too young - the tagline for getting people to wear their seatbelts years ago was: buckle up for safety. buckle up.)
My wife and daughter both owned Tusons. Both blew the motor. One @45000 . The other @ 82000 . Never buy another one
What year are the Tusons?
5 exhaust holes on a 4 cylinder
Looks like fu. I mean fun
My buddy has a Hyundai sedan with a turbo engine. His wife normally drives it short trips 1-3 times a week. Their teenage son drove it through the desert/mountainous area here outside of Phoenix and blew the engine! Now at dealership awaiting approved engine swap.
It's always great to see a teardown with engines that I see everyday in the streets (I'm from Brazil, Hyundai has a very strong presence here).
Also Eric, is the C in Tucson mute? I always spelled Tu-C-Son but found very amusing the way you said it. Great job!
To-sun
It's correctly spelled Tucsan, but yes the C isn't pronounced with the Tu as Tuck, it's pronounced with the san (csan) as somewhere in between son and saan. He pronounced it correctly in this video - TOO-son.
I reused a water pump from a blown motor on a new one last month. Apologies if you felt a disturbance in the Force or the earth wobbling a bit in its rotation.
The world is reeling. Please no.
One heck of a throw with those guides. And while it might look like a Toyota engine, it certainly doesn't last like one!!!
Mine just clicked 300k 01 Corolla le w 1zzfe engine ....I believe is a 1.8.
generally true for Toyota, but much like the claimed reason for these hyundai engine failures, Toyota's new Tundra engine is having bearings seize up due to "machining material not properly cleaned out"
Re: chain guides... "Big Air!!!" Great hang time...
I would love to buy some of the REALLY mangled bits but postage to Oz just a bit steep right now. Maybe later this year. Maybe high resolution photos of REALLY mangled parts might sell? I would buy like half a dozen, plus a REALLY mangled part and make a display “modern art.”
The technicians here might poo poo that idea but they are too used to engines-some of the carnage, “the malice in the combustion palace” is REALLY colossal!
I don’t know why water pumps are so denigrated-often they are in better shape than many other parts-but the, errrr, disposal of them is pretty comic-also a potential great photo/bit of video.
But hey, they got a great deal and 100k mile warranty they don’t cover 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Hyundai/Kia just reduced the recommended OCI on these engines to 3750 miles. That engine look pretty dirty inside. Poor maintenance?
It's a good Saturday night when you get to hear the click click click of some craps getting cammed.👍👍 Good job, Eric. Good job.
Thank you, Sir for an informative, interesting, humorous, enjoyable, and clean ( no objectionable) language video!
