That means your gear box is problematic . Should sent in to check thoroughly.

I have not reached 1000km yet, I can hear a slibht noise compared to the day I got it but I will observe. I don't drive fast, just a normal since I am using it to send my son to school, also I am just new in driving so I am not sure if it has something to do with my driving style.

i just changed my cvt gearbox oil and filter for 60K service at proton sc. now the cvt whining is getting worse and sounds like the gearbox is going to break eventhough at 90 km/h.

is it because the gearbox oil is overfilled? is there a dipstick to check oil level? what should i do? im scared like hell now.... it just a 3 years old car man....

sounds like very serious.. my preve turbo 2014, is using vt3+ gearbox ady.. below 100km/h, gearbox whining sound is minimal.. only can hear tyre noise.. 90km/h is less noise one.. if you said like gonna to break symptom of your preve gearbox, better back sc and show them..

as benny said, maintenance must follow and dont skip.. understand more on your car and treat it good (maintenance).. car can lasts long.. some people complaints a lot, but some people are ok.. either get defect unit or else personal problem..

The mileage on my Preve Turbo is about 31,000km now and the sound from the gearbox, more like low-frequency humming is getting louder. Also the acceleration is not as smooth. Although it is not exactly serious or worrying, it is an observation which shows that the gearbox may be changing in character. I don't know if I should wait until the next scheduled service about 5 more months to get the guys at the service centre to look at the problem.

A caveat is I frequently do hard acceleration with the car. But that should not contribute to the slightly unsmooth and louder operation of the gearbox of the car unless the quality of the CVT is not very good. I did not encounter any problem with my previous Nissan Sylphy of 5 years which I also frequently do hard acceleration. THe gearbox is smooth as silk and silent (I still recall the nice-sounding sound from the engine when the car was accelerating hard in Sports mode).

Did you encounter the gearbox changing character at around 30,000km to 60,00km when compared the car in new condition ie. less than 20,000km mileage?

nope. it sounds the same from 0 to 60000KM. once i changed the cvt oil, straight away out of the sc i notice strange sound coming from cvt. i thought it is going to be better, but after around 300 km that sound still persist. i have no idea what is going on.....

My new Preve Exec have noise (sounds like metal twisting and 'clarking') when going through bumpy road. The noise is from the back. Is that normal?

I didnt hear any rattling noises etc when i received my car until today.

But i feel like the sound sytem is not well balanced. Although i have set the centre to 0.

Also the reverse sensor beep sound is too low.

I havent read the manual yet but if someone knows how to turn the volume higher please let me know. Thanks

try to check at the suspension. it happened to me once that the suspension part is clashing with metal part of the body or something like that. i brought it sc and they managed to settle it for me.

Okay thanks for the information. Will monitor further on the condition of the car before I send it over to the SC for a diagnose and rectification.

Hopefully you can get the problem of your car sorted out soon. Looks like you have done some heavy traveling with 60,000km mileage clocked on the car.

check your rear seat.. fold it down and slam it back to the position.. or else, fold it down, and try drive around and see whether sound still exist

For my case, I just went to regular SC which I always referred.
I ask them to verify if it’s any issue with engine mounting since I felt got vibrated.
After their verify for few minutes, they found there was issue with engine mounting at my car, and need to order the part around two weeks.
Two weeks after that, I received sms which mention that (engine mounting) part already arrive and I could come to SC to fix it during business days.
The claim process just simply like that.

i really need to check / test my car again this weekend thoroughly.

i havent got enough time to test/check everything

and tomorrow send the car to install tint and find the brake lock

Last month the sc change the left hand side engine mounting n the engine shaking more worst but after 1 month they change the right side engine mounting n tell u now the whole wobbling thingy disappear n the noise inside also lower. But not satisfy is each time any claim will take 1 month plus for the parts to arrive n most of the time have to call up to enquire

guys,
wanna ask.
have any of you guys encounter situation whereby the Preve front lower bumper always hit the ground during at the road bumps,certain depth of pot-hole or even steep inclination at certain parking garage?

bcoz when i drove Almera,even at 20-40kmh at the bumps,it still okay,the front didnt scratch or hit the ground where as in Preve case, most of the time especially during tall/thick/thin road bumps.

With the Preve, no issues with road bumps, but on 2 occasions when exiting the basement parking garage at The Intermark along Jln Tun Razak, the car's front lower bumper never fails to hit the inclined ramp, and it always ends with a loud bang as I always drive a bit faster. I am guessing the car may not hit the inclined ramp if the traveling speed is slow. Having said that I didn't have the chance to try driving slow for the 3rd time, yet.

The parts got hit normally r the hooks at the front. Try to bend down and u will c scratches at the hooks and if left long enough rust will start to appear. Preve suspension stiffness and weight can the cause here. As u go too fast toward inclined ramp, the tyre might have already moved up but not the car body, therefore the hook(s) hitting the road. For road humps the same happen n if the road right after the hump is lower, the car weight could also cause the front end to dive more.

From time to time, just sand both scratched hooks with sand paper, wash, dry n spray with black paint to avoid rust.

i wanna ask, the disc brake rotor can see visible scratch, does it means the brake pad no good already? cos i go defensive driving class, they say how to check brake pad, they see my car brake rotor say the brake pad is not good if there is a visible line on it.. they say the pad shouldnt scratch the rotor that hard..

HI sifu's im planning on to change my player for preve exec. Brand preffered is either Kenwood or Pioneer. Any model suggestion. Looking together with GPS navigation as well and also planning to add on amp, woofer and speakers. BUdget for player around 1.5K+-.

Installed Raytech Classic AX series tint for rm900. And ordered Redbat brake padle double lock for Rm350. I hope i didnt overspend
