I've had this piece replaced twice already. All three times it has crimped this way. The dealer is always happy to replace the piece, but shows no interest in determining the cause.
Same problem here. It tears and then rolls up as the window goes up preventing the window from going up all the way. I had it replaced while the car was in last week, and the week before.
Does the dealer care about finding the cause? What are you kidding us? That's funny !!!!
