Congratulations in advance. The list of things to check is on the first post.

Usually there's no paint job problem with Proton cars, but just inspect once so as not to regret later.

Oh, make sure the GPS and navigation is working. There are SA who take away the SD card containing maps and say you need to purchase it

knee down in front of your car... tengok bawah front bumper ada paint scratches or not

try (up/down) the power window on driver's side and look at the power window control panel

How about other electronics? working? e.g radio/light?
Check batt connection at the engine bay. Very common for proton the battery connector not tighten properly.

not sure whether it is from the passenger seat belt...

i took out the whole back panel before to find out where the noise came from...and it seems came from deep inside left rear side metal area which is impossible for us to access..

the sound definitely didnt come from brake light, the steel rod between both end etc as suggested by some members here last time..

quite alot of ppl talk bout this noise last time...but no update/news from them
btw..anyone has braking problem similiar to mine?...whenever i start my car...the brake seems to be hard to press...feels like there are air pressure in the brake...it's difficult to fully press on the brake pedal..which made the car hard to stop when coming out from parking lot etc...need to move for abit distance only the air pressure will be gone then only the brake function returns to normal..my car is 2012 model...told the service centre twice about this..and they did brake service...but didnt solve the problem

No.
My problem is after switched off the engine, fan sometimes running sometimes not to cool down the engine.
I think fan MUST be running after switched off the engine. (before used to drive Myvi, not sure about this).
Is it normal for Preve CFE?

Engine switched off.
1. hissing sound
2. after ~10 - 15mins
3. then, new sound came out... something like "tak" / "toing"(spring putus)

Thank you.

How old is your car?
Mine is Preve 2015 (chassis # 59xxx)

Thank you.

bro, its your left rear seat. try to 'play' drop down with your left rear seat. Me too got the same 'krak krak' before, but completely disappear.

Yes that's the way I did to mine when I first got the car. The noise was ominously sounded like something not being fitted in place, and a good 'humping' would do the job, and it did.

but mine seems like coming from behind the left seat, inside the metal pillar, 

not sure, at least its better than myvi tho,
i drove at corner around 40-60kmh, i can hear tyre screeching sound as it about to skid
while driving preve at thats speed, it feel stable and normal.
thats my experience.

Maybe it's just you, I feel stable cornering at 80-100

80-100kmh speed cornering with confident.
also got emergency brake from 200 meter with +-100kmh speed without skidding and stretching sound.. its very impressive performance for me!
using stock tires.

myvi vs. Preve for handling like langit and bumi.

Definitely not speeding at that road.. As its impossible over there..
Yours should be CFE/Turbo/Premium right? Left side vents are meant to be that way.. If not, how the intercooler will get the air thats needed for cooling? Why u no check when u got the car itself?     

You didn't break anything. The vent is for intercooler.
