I have the S version...6,000 miles. It's perfect!
Mazda is building some of the best autos in terms of quality and reliability. CX-90 looks like a winner.
I own a CX 90. Beautiful, reliable, fast and overall a great quality vehicle. When you own something long enough, eventually things will break and yes, you will come out of pocket. That’s life, and speaks to just about anything. It is a beautiful vehicle and will be extremely reliable for me and my family.
awesome car! but you 100% cannot guarantee the reliability. its a completely new engine with performance over simplicity and reliability in mind. you are the tester for this engine. and if you didnt pay attention to the video the engine its even more complex than a bmw. just to remove the spark plugs the entire turbo will have to be removed. good luck and enjoy it till the major issues arise.
The car has 12,000 miles on her. If something major was going to break, it would have happened already.@@Rockybalboa541
I own a cx-90, you don't need to remove the turbo for the sparkplugs, just a hose that is on top and some panels at the back of the firewall. Definitely more complex that transversally mount 4pot engines but that's the norm with modern premium engines. I also own and have owned multiple bmw and I know how germans like to make things quite complex but it's not the end of the world and the refinement of their engines is quite impressive@@Rockybalboa541
Mazda is the most underrated brand on the road.. they r damn reliable vehicles
not after this engine
I have owned many Mazdas and they are reliable and until the CX-90, very easy to work on. If the CX-90 does need maintenance you are looking at BMW money.
@@clarkkent9080 exactly the 2.5t is a simple, easy to work on engine. Mazda wants to be bmw and bmw the servicing is extremely expensive and the engine has to be dropped for alot of repairs = high cost. Mazda grossly over estimates how much their value minded customers are willing to charge for repairs.
@@Rockybalboa541 made in Japan okay!!! Buying one
@@clarkkent9080BMWs don't cost what they do because of "premium parts" lol. They cost that much because it costs more to ship german cars here (other than the few assembled here) and companies know they can get away with charging us extra for "german luxury". And so far no ones complaining about the 3.3 turbos on cx90 at all. They're having more teething electrical and programming issues, especially with the PHEV version. And parts for the CX90 might be a little pricier, but probably nowhere near as bad as something of german equivalency since we have better importing deals with Japan. In europe german cars aren't that expensive even.
THIS is the engine I want to see in the Lexus IS and RC.
Thanks Great Video
thank you for introduction. 💡💡👍👍😎😎
What is sway bar CCN guy was saying in his video on CX90 is missing in mechanic review?
Is the fuel filter able to be changed out or is it connected to the gas tank?
Your videos are helpful before buying the vehicle thanks for creating this channel extremely knowledgeable channel 3.3 turbo online six-cylinder real wheel drive eight automatic transmission making 340 hp and 369 pound-feet of torque however I learned unleaded petrol I think unleaded petrol we can get rid of bronchitis, asthma, diseases thanks.
Great video! Does the "Advanced Direct Injection" system also have Port injection? To eliminate possible issues with carbon buildup.
no. port injection is ALMOST exclusive to toyota at this point
I test drove one of these and loved everything about it except the sound of the engine. I later found out it has fake engine noise pumped into the cabin. Why would they do this on an inline six, an inherently balanced and typically very nice-sounding engine? I'm now wondering if it can be turned off.
From what I understand, it is actual engine noise piped in directly from the engine compartment. If you don't like the sound, I assume there is some way to plug the sound tube
I want that teardown of that engine
I hope the multitude of engine bay covers does something for sound isolation so as to make it worthwhile to have them. I like the idea of e-motor replacing the torque converter. Does the mild hybrid do away with a starter motor and alternator, and does the A/C operate when the engine is off?
No on all. There is still an alternator, starter and the AC goes warm when the engine is off.
@@TestDrivenTV Oh man that sucks!
I don't think 48V architecture driven by a 0.33 KWh lithium battery is powerful enough to supply load to all sources at once. But I noticed in driving there are some tricks at play... like the start-stop behavior is being driven by the 48V system, not the primary starter. The AC compressor shuts off when i-stopped, but all zones' blower fans can still be set to max speed, catching some recirculated/leftover cold air for a few seconds. And gas engine shuts off while coasting or stopping, with an audible brake regen noise while braking. I don't think the alternator charges the lithium pack but I might be wrong.
@@KillaninjaFC It's a half-baked design. Other mild-hybrids are able to keep the A/C on. I think you're right that the limitation is tied to the size of the battery on this particular vehicle.
I wished someone made a performance exhaust for it or at least the cx60 version I wanna hear that inline 6 it’s too quiet
Really interesting! I just bought a CX90 S trim and love it. I'm still unclear though. How does the s trim get 340 HP versus 280 for the lower trims? Some are saying that it's software, is that right?
Software
Yes the Mazda engine engineer stated that there is no mechanical difference between the two turbo models....all software
S use premium gas, lower trim use regular gas. If you put regular gas in S, you get lower horse power
@@dwang552 Yes but it still has 319 hp with regular gas, the non S trim gets 280 no matter which gas you use
I wish they didn't put the battery pack under the driver's seat for better weight distribution when I'm driving the vehicle alone.
Great engineers have figured out how to make a transmission 10k dollars!! This is RIDICULOUS and saves no fuel its all 100% made to break
I think that I can place Mazda 5 body on this platform, albeit I'd have to use the new dash and carbon fiber some areas for structural work 😋
can you do a direct comparison between the Mazda CX90 Turbo engine to the Acura MDX Type S engine?
One is an inline 6, the other a V6. There really is nothing in common with those two.
@@TDTVGarage Compare how easy it is to service the spark plugs, compare how easy it is to do a timing belt replacement, compare how hard a simple oil change can be, compare how often transmission fluid needs to be replaced/serviced, compare range and fuel economy. Compare the amount of plastic and metal parts are in the engine bay. Compare turbo size and compression.
Can you use regular gas on it without any long term issues?
You should check the owners manual. Generally speaking however the computer will recognize the lower grade fuel and adjust the engine performance down to meet it. You can use lower grade gas, but will get less power.
This engine is a Japanese automotive marvel to the industry and definitely puts Mazda more on the map. I'm happy Mazda is being innovative and ambitious. I'm not worried about this motors reliability as much just on one aspect. Mazda wouldn't spend the money to design a motor that will sink it's unfortunately and undeserved small credibility. Mazda is trying desperately to win customers, not scare them away. I'd trust this engine over most modern American and Korean one's. Look at car repair shops and engine rebuild shops, what brand vehicles do you see alot parked there getting work done? I have yet to see any modern Mazda. I see unfortunately too many newer vehicles with lower mileage needing serious work from all American and some Korean brands, more then most Japanese brands. But I digress, only time will tell ✌🏽❤️
Only time will tell. Unless the CX-90 is 100% reliable, people will be stuck with massive repair bills for relatively simple failures. It will take 3 years when the warranties run out before the true becomes apparent
I wonder if this would fit into a miata 🤔
probably not since it really doesn't even fit in the CX-90
@clarkkent9080 i mean they 2j swap miatas so it might 🤷♂️. I see alot of tuning potential in this engine once all the hybrid crap is removed
@@clarkkent9080 This is not a good engine, at least maintenance wise. Some very questionable and bad design went into it. Should have went with a V6 under that hood, it would have been many times cheaper and faster to work on when time comes.
@@em4703 There was one commentator that said they worked on the design of the CX-90 and there was "co-development" of various components. It seems like that I6 is very similar to a German design.
You could also say that about most germans cars, but aren't they the benchmark in the industry? so, as a consumer you decide what's importatnt to you, and you vote with ypur wallet. Many of us don't care much about that, and more about the refinement, performance, and efficiency that modern engines offer. Either keep the car until the warrantry expires or leave it to the technicians to fix it when the time comes. @@em4703
Does it require 0W20 in turbocharged engine?
Refer to the owners manual
@@TDTVGarage I see that on the oil cap it says: 0w20. Should be the same in the manual as I understand.
It gives a range of viscosities. CAFE standards such as in the US is 0w20. In countries where you can use the best viscosity for engine longevity, it gives other options up to 5w30
Even the battery is not simple to replace. Good luck with long term maintenance
last 3 sparkplugs (40K change requirement) requires cowling and turbo removal
@@clarkkent9080 you have to remove the turbo just for the spark plugs lol what a joke
Well is not like you have to change the battery every year, right? I had BMWs with batteries that lasted 7 years from new. I expect the CX-90 12v battery to last around 5.
@@vargascamilo I agree but why is it so difficult to change common items that WILL need replacing. With labor rates well over $100 per hour, simple maintenance items will be very costly on the Cx-90. All of the CX-90 inaccessibility issues are directly attributed to Mazda's desire for a 50/50 weight distribution for a vehicle that will be driven by soccer moms on school runs.
I drove a CX-90 and was so disappointed. I guess I was expecting the new 3.3T to be like Mazda’s equivalent to the BMW B58, but it didn’t sound good, feel potent, get very good mileage, nor was it smooth at idle. They muffled all of the exhaust noise outside of the vehicle and the engine sounds more like a typical V6 than a silky smooth and free revving I6.
I heard if things do actually break the whole front clip and motor needs to come out for it to be work on...
..ABSOLUTELY. and the timing chain must be changed at 100K miles ( usually that's for a timing belt ) but MAZDA says change the chain, and I heard it's at the rear of the engine, not the front!
Timing chains usually last for the life of the engine with regular oil maintenance, having said that, let the second/third owner of the car worry about that LOL.@@PopsRacer61
@@vargascamilo ..that's true but believe it or not the chain still stretches and the guides get worn also. MAZDA said it has to be changed @ 100K, so you're right whoever owns it then - their problem
one potentially big issue. The two clutches on either side of the mild hybrid in the inline 6 turbo may not be covered under the Mazda Warranty beyond one year or 12,000km. I have contacted 2 Mazda dealers about and Mazda Canada (who told me to contact a dealer). Neither dealers knew the answer and they were contacting Mazda Canada. Two and half weeks later and still no answer. I understands manual transmission clutches not be covered as these are controlled by the driver, however inside an automatic transmission the clutches are controlled by computer programming done by the manufacturer. To me they should be covered. I asked the question because om the Mazda Canada website under warranty it says clutches are not covered and it doesn't say only for manual transmissions. Both dealers thought they would be covered, but thinking and knowing are two different things given the information on the website. If they are not covered I wouldn't buy one for myself. I know the clutch packs in the VW DCT are only covered for 12 months or 12000km so I would never get one of those either. IN my mind it would better if they just mated the inline 6 to a regular 8 speed with a torque converter. Much less complex and likely not much difference in fuel economy.
Good question
The clutches are internal to the transmission and any failure would require a transmission replacement. Dealerships do not fix transmissions.
@@clarkkent9080 Yep and that's why I am not buying one. Technology is too new and the cost of replacement out of warranty would be excessive in my opinion.
Didn't you miss the location of timing chain, which is hidden at the back ?
Timing chains are almost always at the front of the engine such that they can be replaced or checked without removing the engine. We didn't "miss" it, we just usually don't discuss the location of timing chains or belts as it's common knowledge they are always at the front.
Look at the last 2 spark plugs and tell me how to change them at the recommended 40,000 mile interval ? The turbo and more must be removed to access.
...you said 'almost always'. Well I can assure you this is one time the timing belt is at the rear of the engine and has to be lifted out of the bay to be changed, which according to MAZDA, is at 100k miles. Check with any MAZDA service dept. and see what they tell you...I'm not making it up!👀@@TDTVGarage
Could be the next 2jz
Is it a closed deck block or open?
Errr... Mazda most recent front engine rear wheel drive platform was 2016 MX-5 Miata 😂. Mazda is not new to this.
That was evolution of 2003 RX-8 and 2006 MX-5 shared platforms.
Before buying, I suggest watching the "car care nut" mechanic's review on the CX-90 inline 6. He will give a very good perspective on maintenance costs once the warranty is expired. Things do break and unfortunately the design of this vehicle does not lend itself to easy repair.
👍
He's nuts. I bought and haven't looked back
Mazdas are super reliable. I'm not worried
@@mbenton6 I would not be worried ......except after the warranty expires. I wonder why Mazda dealerships have service departments if nothing ever fails?
@@mbenton6you’ll look back when out of warranty and you’ll have to fork $$$$
All that heat shielding to protect a plastic intake manifold? How to over engineer a simple inline 6
technical down side
should be explained
This is an overview, not a pros an cons editorial.
There's a lot of BMW elements in this motor, both good and bad.
BMWs are great cars until something breaks or if you just try to maintain it according to manufacturer recommendations. They are also way over engineered. Example: Instead of the standard no cost metal tab on brake pads that "chirps" when the pads need replacing, BMW has electronic sensors on the pads and must be replaced with the pads at a cost of $95 per wheel. They replaced a simple no cost item with a computer and sensors.
💯. This ^^.
Dude, if you complain about a $95 dollar piece then BMWs are not for you, or any german car whatsoever. German cars are expensive to maintain, has that been a problem for those brands? certainly not, they keep selling more cars every year and they are still the benchmark in the industry@@clarkkent9080
New Toyota Supra engine!?
Plastic intake and plastic valve cover….. yep, seen that before. Not fun once out of warranty
Welcome to all engines in all vehicles today ;)
Japanese has the best plastic. I've seen toyotas and mazdas with plastic intakes and valve covers from 2010 and they still look very much intact today, same for interior plastics. Normally I've seen American vehicles have the worst plastics be it a GM or Ford. And Germans... Well I've seen a lot of broken plastic on VWs and BMWs, just not as corroded looking. But neither are particularly good.
@@know916bound BS. Those plastic valve covers leak. I don't care if its German or Japanese. Its plastic and not a good material to use for valve covers. I've seen tons of Nissan, Toyota, and Mazda with leaking valve covers. A 14 year old plastic valve cover is probably just starting to leak so its probably true you never seen one look bad. Now metal covers with gaskets last way longer.
@@v60polestar88 lol thats literally not a problem with the covers themselves. That has to do with the gaskets underneath which are easily replaceable if you're mechanically inclined. But yes the valve cover may look better or worse depending on the owner by the time its 15 years old. But it won't be a problem for most japanese cars that even a little maintained. Maybe after 30 years they completely fail , because yes they're plastic and clearly inferior to metal ones. But of you even have your vehicle that long its safe to assume it was loved and probably in better condition than most. Which doesn't lead away from the fact vehicles from ("American" 😂) and most German manufacturers are literally worse made.
@@know916bound Its this thinking that Toyota or asian cars are so perfectly engineered that is not true at all. I've own a 2015 Lexus RX 350 and by no means has it been super reliable. The ML amp died and that is a very common issue on all Lexus and if replaced at dealership ists a $4000.00 repair for a damn radio amp. Never had a amp die on any car I've owned. My old 4runner had the 4 piston front caliper problem that plagued all 4runners of certain years and it was expensive to keep fixing. Yes Toyota are pretty reliable but the build quality isnt very good when it comes to rust proofing. In the Northeast they are rust buckets
Come on car makers. So many engines now have the turbocharger sitting on top of the motor for space considerations. Dumbest move ever.....too much heat given off cooking electronics, plastic piping to become brittle, etc. All of the heat shields will not be of help. 8-10 years from now, it will be interesting to see all of the problems with this engine set up. Keeping my CX-9. Which in my opinion will give me much better reliable service in the future.
Because when they buried the turbos down low under wverything in the 80s and 90s it worked out so good for the wiring, hoses, and plastic?😂
The 4 cylinder is non-turbo
i hope they dont give this to the mazda 3 since i just bough 1😥
Why is the Mazda warranty so skimpy? My last car warranty was 5 years 60k. That’s should be the norm.
I like the CX 90 except, does anyone know more about the problems the Texas Truck Channel brought to attention about the vibration and noise under the floor board?
it is 3 years, but 5y/60k for the powertrain and 10y/100k for the hybrid system.
YUCK!! It's a hybrid with a battery that might burst into flames in your garage!
If its nickel metal hydride its safe. Lithium batteries are the problem
get used to it, in a few years most cars will be mild hybrids at a minimum. BTW, what kind of battery do you carry all day in your pocket? litthium right, so yes there is always a concern but come on! you are surrounded by items that have lithium batteries all day long. Tech will only get better.
So it has a crappy CVT
Um....Nope.
Get informed, Mazda does not have a single car with a CVT, they know what they are doing.
This engine is really overcomplicated, they made it an inline 6 cylinder which causes cooling issues (in a larger engine it's harder to get even heat distribution) that leads to extra effort with the electrical part and etc, the turbo itself is not a simple component but here again it was not done in the simplest way and I did not talk about the transmission which is also new.
Yes, this is a good luxury car, however there are questions about reliability and repairs costs what makes purchasing this car only as a lease option.
