CVT Actual Failure


Can anyone report an actual Failure of a T31 CVT?

By this I mean broken or unable to move the car due to actual catastrophic mechanical failure eg bearing failure in the transmission, cvt belt failure, broken gears or pulley mechanism, valve body failure etc etc.

By this I Don't mean failures of Transmission Management Computer, Shifter mechanism, temporary limp mode problems etc. and CVTs replaced under warranty due to the Noises reported in the other topic Here.

reason for this question:
The T31 CVT models have been out for some 6 years now and given all the endless and necessary posts about CVT problems, I haven't heard of an actual failure. All the problems seem to be owners and dealers concerned about transmission rattle/noises at low speed etc etc. Also the occasional CVT going into limp mode or a low power mode (covered HERE perhaps). Many CVT transmissions replaced due to the rattles etc.

Now Nissan are stating, it seems, that in spite of low speed rattles and noises when "Feathering" the throttle ie no drive or retardation (engine speed matches road speed) that these replaced transmissions have no fault.

My second CVT transmission at 60,000kms (car at 90,000kms) sounds now like the first when it was deemed faulty and was replaced.

HOWEVER, there are no bearing noises or any other scary or worrying issues at all when I Drive the car. Only when there is no drive/retardation or at very low crawling speed.

The noises and rattles could entirely be due to a little normal wear in the gear train - similar to differential backlash - that is simply not so well controlled by the Transmission Management Computer (TCM). Older cars have no such computer management and do have the identical rattles/Backlash at low speeds or when feathering the throttle and continue on to many 100,000kms trouble free.

If this is the case then owners worried about premature actual failure can be re-assured there is NO PROBLEM.

If T31 CVT have actually Broken or Catastrophically failed (you know what I mean) then we should be very worried.

SO - ANY ACTUAL Catastrophic Failures????

Re:


I am not sure what is the logic behind your questions mate!

You paid close to $50 grand for a product that you expect to perform without any issues for years and for the manufacturer to solidly confirm that major components in the car like the transmission are defect and problem-free.

If you are saying that you are happy to live with "non-catastrophic" rattles in your transmission just because someone is going to assure you that your car won't stop in the middle of nowhere, then it is your choice...but I would certainly not accept such an explanation regardless of it being a simple rattle (which is not) because JATCO the CVT manufacturers themselves confirmed the defective part in the CVT production and that fact alone warrants a replacement of the transmission with no questions asked.

You are paying top Dollar for these cars to expect them to last....otherwise, we might as well buy a Hyundai which comes with 5 years warranty and then throw it away after 5 years to buy another one. I reckon it will be a cheaper option and hassle free.

Sorry, but I don't agree with your analogy and I wouldn't expect any other owner to do so either.

This type of argument can only come from someone like the manufacturer themselves who will try and do anything to wiggle out of replacing a defective transmission!

Re: CVT Actual Failure


Hi Jalaski.

Totally agree with your view on the issues raised in this forum and Nissan's abysmal response to owners concerned about the CVT issues well covered here.

I wasn't aware that JATCO admitted there were faulty CVTs - can you point me to that documented somewhere as it would be useful?

I thought CVT were replaced out of "goodwill" to satisfy customers regarding NVH (noise, vibration harshness) and not an actual fault. I did hear of rumours about faulty material in some early bearing batches but this seemed unconfirmed. Other rumours were about less than ideal TMC control of backlash and a firmware update corrected this sometimes.

There are many of us owners who are, however, STUCK with our T31 XTrails and are unable to trade out of our situation to a better/newer car or have the ability/energy/opportunity to fight the long battle with Nissan to properly address our worries that the T31 Xtrails won't last.

For this reason I wonder if any CVTs have actually failed, rather than just become noisy when "worn in".

It would be nice to know that in spite of the issues the car is actually just a noisy but reliable vehicle ( that we otherwise really like) and Not a Lemon.

That is the point of raising this question and not with a view of sounding like a Nissan Australia Rep (may they . . . . . . )!

Re: CVT Actual Failure


I completely understand the logic here. You had something replaced under warranty. You now fear the same part needs replacement again but this time it will be at your own expense. Do you go ahead and replace it or do you just live with the rattle knowing that although annoying it will not leave you stranded one day. I would want to know the same thing.

As for the Hyundai comment- after having seen first hand how they treat their customers with warranty claims I would have no hesitation buying a Hyundai over a Nissan off the showroom floor. Hyundai will actually fly a head office rep to any dealer making a warranty claim to personally assess the situation. No mucking about with phone calls, emails and photos. After all isn't a huge part of the reason we buy new cars the perceived reliability and manufacturer support via warranties.

Re:


The information about the JATCO bearing failure is in the existing CVT thread you will find it as a reference in many other forums around the US as well, especially the Murano forum. It is the main reason JATCO upgraded the CVT transmission because car manufacturers (other than Nissan) signalled they will stop placing orders with them.

Todd: The Hyunday comment was made as a compliment to Hyundai actually. Even if their cars lasts 5 years only (which is far from the truth I know), at least you won't have to go through the fights and headache during the warranty period like Nissan owners currently do.

And finally, if Nissan Australia refused to put a life expectancy on a completely functioning CVT transmission in the recent case (which is recorded in the CVT problems thread) and they couldn't say how long it will last if driven normally and serviced regularly, do you think they will be able to do the same on a transmission that is exhibiting problems? I doubt so.....but I agree it would be nice to know indeed.

After reading many horror stories about the failed CVT transmissions (more so in the US than here), I haven't come across any story of a CVT owner being stuck with total CVT failure, having said that, it may be a bit too early to start hearing about such stories....

Re:


Im not sure what noises you guys are talking about.
Could someone please tell me what a "Noisy" CVT sounds like?

Mine moans and graons at low speed, with a bit of wirring noise at walking pace, but over all its nice and quiet.

I used to own a Valkyrie motorcycle.
Its gearbox was perhaps the noisiest gearbox on the market.
General driving it sounded like nothing but a turbine and it got louder the faster you rode.
However, thus gearbox was indestructible, I could and did (for a dare) tow a 1200 kg boat and a small caravan.
It was klunky and brutal, but with a 1.5 litre 6 cylinder engine fitted with 6 carbys (one for each cylinder) a very strog gearbox was needed.
In the 12 years I had that bike, it never missed a beat.
And I have never heard of anyone ever breaking the gearbox.
You could quiet down the gearbox a little using synthetic oils, but it still was very noisy.

What Im saying guys
is if it makes some noise, but is otherwise sound and strong, who cares?
Just turn up the radio.

Ill willingly trade a little noise for the X Trails benifits any day.
