We didn't no more than get our new 2008 dodge avenger home from the dealer and we noticed that there was air leaking through the back passenger door, you know like when you don't get the door shut all the way. We took it into the same dealer 4 times. the first time they said, adjust the latch, the second, ice build up, duh, of course there's gonna be ice, the damn door didn't shut, third time they replaced the weatherstrip. None of that helped and at this point I was tired of the dealership and went to another. Finally, the fourth time, they got a body guy out to fix the problem.
