No need to wait for recall. You can claim the faulty mounting at SC.

So, you don't do hard acceleration and only do high speed cruising up to 170km/h with your car. If that's the case, then it is only high speed cruising that may be one possibility that has led to the transmission problem of your car. Just a guess, as it can be due to other causes and not high speed cruising.

I am trying to pin-point the possible causes to the CVT giving problems, whether it is due to constant abuse (frequent hard acceleration at high RPMs), frequent high speed cruising >150km/h or something else, whether it is a mechanical fault or defect of the CVT. At any rate, I do feel that the CVT the Preve Turbo isn't too robust or reliable if subject to frequent (or maybe occasional) hard acceleration or high speed cruising at high RPMs. I may be proven wrong as other owners who frequently do hard acceleration or high speed cruising may not encounter any problems with the transmission of the car.

In the earlier days, I used to do hard acceleration on the car quite frequently with RPMs above 4,000. I am thinking this action may be one possible causes of the sound of the transmission getting louder by the months, and also the occasional loud "woo woo" sound after a bout of high speed cruising.

As for your question whether hard acceleration will have long-term effect on the CVT, I do think there will be, judging from the performance of the transmission just below 3 years. I have refrained from doing hard acceleration on the car since earlier this year due to the behavior of the CVT which seems to show that it isn't too resilient when being pushed hard.

I am curious to know if there are any Preve Turbo owners who often do frequent or occasional hard acceleration and high speed cruising on the car and did not experience any peculiar behavior with the CVT.

My car is soon to be 2 years. Last few months, everyday without fail, I do full throttle accelerations. Nothing peculiar yet, but I do see the behavior that the first cool down, the RPM is high with loose feeling (because of higher RPM even at slow speed) upon first re-acceleration.

An update. I sent my car for servicing this morning and lodged a complaint on the transmission giving a weird and loud sound. Upon inspection, it was found that the entire gearbox needs to be replaced with a new one. I asked the service guy who checked my car on the possible causes of the damaged gearbox and he did not have a definitive answer. I guess it is a case of a defective or faulty gearbox.

I need to leave the car at the service centre for about 1 week and no replacement car is available at the moment. The spare part (gearbox) is currently not available at the service centre. They will need to submit a report before the gearbox is delivered to the service centre to have it fixed on the car and tested.

Idunnolol - despite your parents driving the car gently the gearbox still needed to be replaced at 17,000km,  it looks like driving style and pattern (as in hard driving/acceleration) may not be the primary factor in contributing to the damaged gearbox. It may be more to the quality of the gearbox that has affected the earlier batches of the car. Not too sure if the later Preve models year 2014 upwards with the improved gearbox are affected.

I sent to COSE in Shah Alam beside KESAS highway. So it takes 2 weeks for the gearbox replacement? I thought 1 week is already long and asked the guy to speed up the works. Looks like I now have to anticipate a longer time to have my car back.

If you car is year 2014, that means that the newer Preve also have this gearbox issue. I wonder what is the cause of the gearbox going kaput. May I ask how did you parents get to know that the transmission is problematic? Did your parents found out when they discover some symptoms such as louder sound from the gearbox transmission, or the service centre found out that the gearbox is broken when the car is sent for servicing?

mine got this whining noise at 30-50km/h, but i tried new iriz, their CVT has no such whine at all. Mine is like woo woo woo when lift pedal at 30-50km/h. Even when step pedal also got abit but not as loud..

I finally managed to find a video that shows the closest noise that I experience with my car.



Fast forward to 0:30. The background sound from 0:30 to 0:42, about 12 seconds. This sound is almost similar to the sound of my car's transmission. The only difference is the driver in the video above is reversing the car in R, whereas I am accelerating the car in D.

Oh wow.. My car has that sound when reversing too.. I thought it was normal? And I do have an aeroplane sound when accelerating? It will be gone with higher speed though.. Is this normal? Also it tends to rev higher after cruising at high speed.. Say u r at 170 and approaching a tol, u get slow down and get into smart tag lane, after getting pass the barrier, u step on the pedal LIGHTLY, the jerk will have a bad jerk and rev  more than usual with that throttle input..  I have never driven another CVT other than a Vellfire. Vellfire's CVT has no such things though.. Looks like it's time to get it checked at a service centre..

Better get your car checked to be safe. Aeroplane sound is normal and is inherent in the CVT I believe. It is the additional loud "woo woo" sound from the transmission. Once you hear it, you would know that it isn't normal and there is something wrong with the transmission. In my case, it was intermittent and comes up once in a while, not always, so I didn't take it too seriously. Only after I sent it to the service centre did I know the extent of seriousness, in that the gearbox of the car is damaged.

I have driven my previous car, the Nissan Sylphy which also comes in CVT for more than 5 years in the same manner as the Preve Turbo with frequent sprints sometimes RPMs climbing high above 4000 in Sports mode. There is no issue with the transmission at all, no change in character even for a tiny bit. The acceleration remains silent and super smooth. From this experience as well as some other cases as shown on Youtube, I am beginning to feel that the CVT in the Preve Turbo isn't too robust or reliable. The fact that the transmission can become damaged even though it isn't subjected to spirited drives as in hard acceleration or high speed cruising suggests that the quality of the CVT is not very good.

May I ask if your parents' car is now working fine now? Any vibration and woo wooo sound during low speed acceleration from standstill and low speed driving? FWIW after 5 visits to the service centre with all engine mountings and gearbox mountings replaced, the woo wooo sound from the engine during low speed acceleration is getting louder and worse. Even when the car is not moving, stationary at traffic lights, the woo woo sound can be heard. It sounds like the engine is going to go dead or something. Really bad condition. I have to schedule another day to bring the car to COSE for the 6th time. I wonder what is wrong with the car.
