There was a bulletin to spray wax sealant under the weatherstrip, It applied to my 01, and they did it? Just recently I found rust and peeling paint under both front doors. The dealer examined it, and the body shop came up with figure of around $1500. I have a good friend (shop manager) who got the the dealership to agree to cover $500 of it. After some more negotiation, the body shop agreed to do the repaint at "warranty" rate of $1200 and split the cost 50/50. I am not convinced they did all they promised, they were to repair both fronts and check the rears, I doubt the opened up the doors.
Good luck, in trying to get help
