i think proton is really trying their best to give best service, so far i am getting quite decent after-sales service, just i dont like the fact i need to use their engine oil provided at SC for the warranty purpose. My SC only provide shell helix ultra for full syn, around rm220+ include labor where i can get petronas syn3000 around 200? which is more suitable for turbocharged car.

btw if my car still going to the left side of the road, even after do tire alignment everything, what should i tell the SC? becos last time i tell the SC they say do alignment for me oledi but still eat to left, they tell me the road is slight tileted to the left, but the problem is if i try to drive the the opposing lane when there is no car coming in front, the car still going to the left, slightly. So i need to tell them wat to check, sometimes they are not so brilliant.

Hi ben, you mean noisy driver seat can claim warranty? Mine is noisy since I collected the car. From other owners, I was told this is something that cannot be fixed. Please kindly enlighten. Thanks

mine now is not tat squeaky compare to my first seat. I dont know what they did but they actually did fix it. Most of the time the change of seat is due to berbulu.

tq will look forward for it

Preve CFE seems very nice...

after reading though page 1, lots of my worries are gone...

TBH, should i replace my trouble-free-but-rattling inspira with preve??
AFAIK, the boot are bigger, performance are better...
i'm not new to Proton, as i have driven and own lots of proton cars before..

No need to change from Inspira to Preve.

Not all Preve are rattle free also.

It's been a long time since I'm last active here.. Anyone here still face problem of CVT heat up issue when cruising at high speed? I kena twice alrd this week on highway. Drive high speed halfway the CVT light lights up, then the transmission went dead. Have to stop at emergency lane to restart the engine. Just 170km/h leh.. Engine can tahan but CVT can't?

Not worth it if coming from Inspira.

No issue so far.

bro, my car twice already today second day hard to start during early morning. Today it stalled for the first time showing the battery is low. Should i go back to the shop to change to the same rating battery? i scare the shop doesnt have the same battery. Or should i go to SC have it checked?

I have occasional issues with the CVT during high speed cruising, but my problem is not the same as yours. The CVT lights did not come up on the screen. What do you mean the transmission went dead? Do you mean the car shut down by itself on the highway suddenly? If that is the case, it is very dangerous, and is a serious problem.

My experience is after high speed cruising (not every time, maybe a frequency of 1 in 10), when the car slowed down considerably, the car(or the CVT) will show a very loud "woo wooo woo" sound when I step on the pedal to accelerate the car. There is a feeling that the engine of the car is going to shut down, but it didn't. After several seconds, about 5 to 10 seconds, the wooo wooo sound will disappear and the performance of the car is back to normal. Somehow, this sign is not good. I will ask the guys at the service centre to check on this when I send my car for service in several days time.

To be frank, I have a feeling that this Preve is not suitable to be driven at high speeds to often. Somehow the CVT is not very robust to be pushed too often. I do occasional high speed cruising and apart from the sound from the CVT getting louder by the months, this occasional "woo woo" sound from the CVT may be a sign that the transmission is not too reliable or robust when the car is subjected to spirited drives. I am not sure about others who frequently do hard acceleration with the car, whether they have encountered similar symptoms as what I am experiencing right now.

THough I have to say, your case is very serious and dangerous, the engine shutting itself down automatically on the highway.

By the way, after the engine went dead, presuming your car was still on the highway when the car had shut down, you can still turn the steering wheel and manouvre the car to the emergency lane?

The engine did not went dead. The temperature indicator did not rise either. Suddenly the CVT light just on. It's like the gear automatically shifts into neutral. RPM drops drastically, when u step on the accelerator pedal, it will struggle to rev and will not accelerate. Tried shifting into neutral and back to D also cannot. The only way is to stop the car and restart the engine. So assuming u r on 170km/h, u will have all the momentum to coast to safety before it reaches 0km/h.. Still dangerous though. and I thought the stability of the car and the turbo engine make the car great at high speed....

Some people seem to have this issue of cooling. I never held mine at high speed for too long, maximum also 190km/h for 1-2KM stretch, so I never got this overheating. Should you try to ensure that your radiator and transmission cooler are all clean and not blocked by road debris? Lol.

This problem is common among CVT cars, not just Preve, especially if you're using Mitsubishi Lancer. The same goes for Inspira, but Proton has already improved the Inspira's CVT cooling system.


Low battery sign could be false positive. Reduced CCA could have raised it more easily but since the battery is new, you should able to use it.

The shop probably won't be able to change for you without charging you.

Could it have been hard to start due to other issue such as dirty throttle body?

ok so i will have to let SC clean my throttle body? I saw somebody in the forum with such problem too.. so i would like to know wat is the fix on it.

I once had hard starting. Actual cause is unknown because it didn't get fixed right after cleaning throttle body. Problem went off by itself.

Noted. So the car will not respond to pedal action and there will not be any acceleration when you step on the pedal. Still dangerous but at least you can still steer the car to the emergency lane to restart the car, then it is not too bad.

Have you brought the car to the service centre to have it checked yet? Is your car the low spec Preve or the high-spec Preve Turbo?

Mine is the high spec CFE. Entering year 3 now.. Yup the car doesn't respond to pedal when the CVT light on.. I haven get it checked yet.. Will ask service centre next.. Just wondering if later batch of Prevé got this problem..

Mine will be 3 years this month. Looks like we got our cars at almost the same time.

Yea.. Should ask service centre to help me check during next service. It just happened twice this week, suddenly no confidence to run the car at high speed..

Apart from high-speed cruising, do you often or usually do hard acceleration ie. stepping hard on the accelerator with high RPMS up to 4000, or the RPMs are kept at around 3000 or lower during acceleration?
