Noisy window glass & dash board on rough road
Pros : power
Cons : power window
Its window glass makes lots of noise when half down. You can not drive the car with glases half rolled down. And for this GM also has no solution, its a manufacturing problem.Even dash board also make CHi-Chi noise while driving. Service engineer told that plastic is new so its making rubbing noise; it will take some time. But today 01.04.13 its been around 4 months still sound is there. When 6 lac car makes noise in first 3 months it feels really bad.
