I recently purchased a 2002 VW Passat GLX 4 Motion Wagon. Have approx 1000 miles on it and the windshield has developed a fine crack on the passenger side. The crack appeared last week when we got frost in CT. I don't see any point of impact although the dealer claims it is caused by outside influence. I think this is a manufacturing defect. Has anyone else experienced something similar. Your comments will be appreciated.
