open door (leave open), start car from cold. get out and observe the top edge of the door. does it shake up&down? if so please post the following info, it may help determine build date and/or model issues:

1) model/year
2) build date
3) what oil grade in the motor
4) what the outside temp was

 

i got that issue only when the car is cold.

1) 04
2) have to check that
3) whatever dealer puts
4) dunno (will do all this the next time)
