I just happened to log in n saw these comments..so I thought I share my experience with my 2012 first batch preve...few months after buying my engine cylinder head cracked while driving n towed to proton and they replaced the engine...took about 1 month plus replacement car given...

everything went fine and after tht the car would jerk when I drive slow and feel like the gear slipping..went twice and they retune or reflash the ecu and it was ok but after sometime it felt the same.. learned to live with it..

then one day the aircon was not cold went and checked everything connected to aircon was fine but air not cold..it spent 3 weeks in workshop trying to pin point the source and apparently some wiring problem..

my driver seat is worn out in 3 years and emit some sort of "creaking" sound everytime I sat on it or moved while sitting..morning when I start and drive there are lot of vibration in the dashboard....

the engine sounds so rough inspite always using full synthetic oil..the absorbers has already worn out and due for replacement...as for the vibrations I am sure the engine mountings has to be replaced..

the engine will die off while I reverse on uphill..sometimes as I slow down for touch n go and when I press accelerator there will be a violent jerks which I feel on my floorboard before the car actually moves on....

the cvt fail indicator and airbag indicators will sometimes light up and I need to go proton to reset..twice already..

the gearbox feels much better after my major service in 60,000km and they charged me RM1500 for the service and I noticed they changed lot of gearbox parts....

honestly I feel frustrated and disappointed with this preve as so much of my time wasted in proton workshops..i really don't take this car outstation as always one after another problem crops up..

not all but they charged rm 200 for the a/t valve body ...i dont knw wht part is it ...they did change some other things on the g/b but i am not sure wht it was as i was not charged for it..but in my opinion the major service is quite pricey ..they changed plugs,coolant,fuel filter,oil pan gasket,brake fluid,air filter...

the problem is they dont do proper recall like when i went sc when my oil cooler hose gave way and the engine oil started leaking...they took the opportunity to change the wire harness for the fan motor as they said many preve fan motor fail caused by wire harness somthing...i had to leave the car there for a whole day...

jus my sharing ...

i bought my preve cfe in july 2012...almost going to be 4 years
it had quite a bit of problems ranging from engine to aircon to oil cooler to etcc...
which i don't want to share as it will be very long...
previously i switched to aftermarket 17inch rim & due to the weight of the riims the acceleration , top speed & petrol consumption suffered so i changed to the R3 17 inch rim and everything was normal as it weighs the same as OE 16 inches rim.

The top speed i got so far is about 210-215kph..always in D mode only as i feel it is more than enough.. consumption is worse if driving around short distances like around town but is good for long distances..

i never use the paddle shifts as for me it feels very artificial and not relevant...i don't have problems outperforming other cars at traffic lights but i agree that it takes a bit of skills and practise with the right amount of pressure on the accelerator pedal , otherwise the momentum will be broken....

at highways speeds i can keep up with the relatively big boys but sometimes its quite subjective as some of them do not want to push their cars to maximum , hence they let us win and we on other hand think they got no more juice...

has anyone here hanged their preve cvt gearbox to another g/b ?? currently i just have a niggling problem with my g/b and i am really not interested to fix it anymore..

when i have load...like carrying 2 or 3 people on board the g/b behaves "funny".. it simply sense the throttle input quite late than normal time (single occupancy) and the result is the car jerks violently everytime when i slow down and accelerate...like taking sped humps..uphill stop start situations and even at slow traffic light stop and go...

already preve's respond to throttle input is few seconds slow and with load it's terrible and embarassing for my passengers...my passengers are not my family and it very embarrasing for me them as they feel awkward at being able to feel the jerking....

i have already previously fixed it at proton but it is re-occuring...meaning they don't have a permanent solution to this and i will have to make several trips to SC on top of the 18 times i went in these 3 and half year of ownership....

so if there is a simple solution to it pls share ....tks a lot

my transmission emits the normal cvt whine but i think its normal and my car dashboard to the door trim to the seat and the glove compartments everything vibrate badly after the first start in the morning and eventually the vibation lessen...nevertheless the vibration is still there...i have changed all my shock absorbers and abosorber mounting as well.. i guess i need change the engine mountings at next service 80k
