Oh well, from ur post i know u didn't know ur car construction at all...if you got time, open the door panel, look into it, if only the plastic vibrate noise then i will definately can fix it by using tape and sponge...this is design problem, not becos of the hot sun...and tell you my car only 3 weeks old, not even reach 1000km yet...

Men, no people here want to blame another for the flaw, but just dun't simply said this is cheap car and use others expensive car as example to prove your point, this is annoying. What i said to knight was the car got this kind of problem, i don't want to praise Proton blindly just because i'm using BLM now.
