How old is your car and is it the low-spec Preve or the high-spec Preve Turbo. Certainly a very serious problem and the service centre needs to fix your car immediately.

Horses for courses. Personally I would not recommend doing soundproofing. You may reduce the engine noise with RM1k-2k soundproofing but there will be other sound that may pop up later from inside the car(rattling of dashboard, squeaky sound from seats etc.), nullifying the soundproofing done to filter out sound from outside the car(engine, wind, tyres etc.) marring the driving enjoyment. And on top of that, when selling the car, all the cost that goes into the car will usually not be recovered.

In summary, I am just not into soundproofing or doing any sort of modifications to the car. Everything stock is best. What I think is if the car is quiet, it will be quiet. If it is noisy, it will be noisy. Similarly, I find the engine sound to be rather harsh and noisy during acceleration when compared to Japanese car. Overall NVH(wind, suspension and noise from traffic) is quite good to me. The sound from the traffic is quiet muted and the suspension does not make too much noise when going over bad roads or bumps. It is only the engine sound and CVT whine during acceleration that are slightly lacking.

As usual, horses for courses.

Sorry, forgot to mention about the "tak tak" sound from the back seat. In the first week when I received the car the sound was already there. After trial and error for about a month, the sound went away by itself. Try opening and closing the back seat several times. For me, it worked.

The sound that is bugging me now is not from the back seat but the front (driver's) seat. I have got the whole seat changed to a new one and still the sound is there. Hopefully I'll get it sorted out the next time I am at the service centre.

About 6 years ago I have done RM300 soundproofing on all 4 doors of my Nissan Sylphy which is already a quiet car. Although it is quiet, I am still "curious" whether this door soundproofing will be effective and transform the car to even quieter, to further block the sound from traffic. After the soundproofing, I realised that there is very minimal difference, in fact zero improvement. If there is a slight reduction, it would be in my head.

When I did the soundproofing, another guy also did on his Sylphy, also from the same guy who is promoting the product on Autoworld forum. Similarly he did not find any difference, and also mentioned it may be in his head. Though there is a difference in the feel of the doors when closing and opening. The doors felt slightly heavier and the sound of the doors closing is slightly different with a heavier thud.

If you go onto Autoworld, on the Soundproofing section, you will notice on the mixed receptions people are getting. Some spent RM3k to 4k soundproofing and are still not satisfied with the results after spending that kind of money and swear not to go int soundproofing anymore. Though there are some who are delighted with the results. As I have mentioned, it is horses for courses.

Personally if it were me, I would not waste money on soundproofing. Of course, soundproofing will work. It will reduce the sound of the engine to some extent. The real question is whether it is worth it, for a slightly reduced sound you spend more than RM1k(the sound of the engine will still be there, just slightly softer).

Having said that, you can still try the door seals if you want since it is cheap. But I think the NVH of the PReve Turbo from the traffic is quite acceptable already. Only the engine and CVT whine is a bit loud. Soundproofing to the engine will be significantly costlier.

The car is still under warranty in which Proton shall fix it. Not sure about the WD-40 but if that is required to fix the sound then Proton shall do it and not the owners in my view.

The sound from the seat is actually what you are describing in your last sentence. Whenever the driver moves the body, there will be noise from the seat as if something is moving inside the seat. Either the airbags, air pockets or some spring as you have mentioned. Not too sure if this is related to the WD-40 solution you said earlier.

For door seals, as mentioned before I have done it on the Nissan Sylphy, no difference. Maybe there will be difference for the Preve, but at 120km/h and above, the sound from the engine will be louder than the wind noise and will basically overwhelm any other noise in the car.

As for your RM50 in producing "great reduction in engine noise", it is contradictory with your earlier sentence that we need to spend more than RM1000 for the soundproofing of the firewall for the engine. Anyway I highly doubt RM50 can produce magic.

The back number plate of my car didn't fall off but it looked very flimsy at the edges and is curved outwards. Hence I took my vehicle to the nearest service centre to have it fixed. They used higher quality 3M double-sided tapes at more locations so it is all good now. The guy mentioned most stock vehicles use lower quality (and lesser) double-sided tapes on the car plate number and that may have resulted in some number plates falling off. No specific arrangement but basically just use more of those tapes, and the higher quality ones.

No problem. Yes, the SA can help you if he/she happens to have high quality 3M double-sided tape. In my case I took it to the nearest Proton service centre (since it is a waste of time to go to COSE for this small issue). If I'm not mistaken I didn't book for an appointment and just walk in. Since it is a small issue the service centre can accommodate.

I looked at the guy who is fixing the double-sided tapes on the car number plate. You may ask the guy to add more but if it is 3M double-sided plates that it should stick well. I noticed the original double-sided tapes are smaller in width compared to the thicker 3M tapes. And very few double-sided tapes are used too.

When I took the car, the car number plate is actually tilted to one side (slightly slanting position) and not exactly a perfect horizontal. The SA fixed it for me.

What is "kns"?

In most cases, when taking delivery of your new car which is already registered under your name, you can still "reject" the car due to some flaws, but in the end the car will still be yours unless it is a very serious flaw and you do not want to accept the car. Things such as dent on car body or scratches/tear on the leather seats etc. All these can be fixed by the respective vendors. The Sales Advisor's task is doing the arrangement works in calling the right person to fix the problem for the car owner. Usually they will make a note on the Delivery form when you receive the car. You can still drive the car home and the Sales Advisor will schedule the time and day for you to bring the car to the showroom or workshop to have the problem fixed. If it requires repray of metallic paint it will usually take 2 days and you may have to leave the car in the workshop overnight.

So in summary, if there is anything wrong with the car, you can send it to the service centre later. You may choose to reject on the spot, but it may take the several days for the Sales Advisor to arrange to have your car fixed. Unless you really don't need to use the new car, you may choose to reject the car and let them take their own sweet time to fix the car for you, say up to 1 week or more.

Just once or twice if I'm not mistaken in a span of 1 year. Now it doesn't happen anymore though.

Quite a lot of issues you are having with your car there. Sorry to hear about the problems though I hope you could get all of these issues fixed soon.

Some of the problems such as shaky steering and unresponsive pedal are mechanical-related which doesn't sound too good.

I find the stock tyres on the Preve Turbo (Champiro Bax) to be adequate in terms of performance, grip and braking. Noise levels from the tyres are acceptable as the sound from the engine is louder and overwhelms the sound from the tyres at higher speeds.

Though the Champiro Bax tyres emit a screeching sound when on bends or corners at moderate speeds.

No worries. You don't offend me with your opinion although I am a Preve Turbo owner. It is an unbiased view which I appreciate. As a matter of fact I do agree with what you have said. The car is good at its price range of RM69k+(though I understand the car can be had cheaper now) and trumps the Toyota Vios and Honda City (RM90k+/-) in terms of value and performance.

The main or major gripes of the vehicle, to me, are in the unrefined CVT and the loud engine noise. No other major issues. Thin fabric seats may not be as comfortable as the softer and thicker leather seats of imported models which are higher quality, but can understand the limitations given the low price tag of the car.

I would still recommend the Preve Turbo for fresh graduates and those on a budget, or those who want a relatively powerful car with good handling.

For those who can afford it, there are better cars of course, but they usually are 2 times the price of the Preve Turbo, or more. But when it comes to value, there is no denying that the Preve Turbo delivers.

Of course, for those who can afford a RM110k+ vehicle, I would not recommend the Preve Turbo due to the minus points as mentioned above.

Not sure if you are looking at the low-spec Preve or the high-spec Preve Turbo.

Almera is good for city drive and more fuel efficient than Preve Turbo but in comparison the Almera is underpowered on some difficult stretches on the roads. The Preve Turbo will be much more powerful than the ALmera. If you are familiar with the stretch along the North South highway from KL to Ipoh, just before the Teluk Pulai exit there is a steep gradient where the speed is limited to 80km/h up the slope. One of our colleague's Almera struggled hard as the 1.5-litre engine seems to be running out of steam when going up the stretch. You will just glide through the stretch with the PReve Turbo.

Nissan's vehicles are rather poor in handling and power, especially the Almera. The Sylphy is much better than Almera but the current "downgraded" 1.8-litre Sylphy may not match the Preve Turbo in power.

However, if you want quiet and refined drive the Almera will be better than the PReve Turbo. The Preve's engine and CVT are indeed a bit noisy.

For those who got the free YES wifi device that comes free with the Preve Turbo, do you still get the free line after 1 year? Surprisingly, it is already more than 1 year and still the line of my YES wifi device is still active.

I thought the line of the YES device is only up to 1 year?

Sorry, but I'm not paying for the YES line. It is prepaid right?

Yes, that was what I thought. After 1 year the line will be cut off. But my wifi device is still active after 1 year 3 months. Funny.

Nobody is stupid. It's a small piece of wifi device, black in colour from the company "YES", given free to those who bought the Preve Turbo sometime last year.

The YES is prepaid. YES can charge or bill me but the bill hasn't come. I'm just waiting for them to terminate the line but up to date they have not terminated it. So it's free internet data usage for me now.
