Were you able to get the fix from the dealer covered under warranty? When I went in for a rattle when I first got my car they were saying they only covered it since it was only two weeks old. I've had it now for about 19 months and the headliner rattle (overhead console) started about two weeks ago.
Also how long did the dealer take? I don't really want to leave it with them overnight since I don't have a backup car.
