The drivers side windows were pitted almost like a front windshield gets after years of driving. There was no other damage to the chrome trim or paint. I felt it was a defect in the glass. The dealership Regional Manager did agree to fix but only under a "good will" fix and not under warranty. Acted as if I had done something to the car. As no other damage was evident to trim or paint, what could have caused the chipping/peeling?
