Who said the owner was at fault??A6Pilot said:Roger-
Maybe, just maybe, there was a defect in the window glass, or glass installation, as the car rolled down the assembly line. In my case, (see above), the dealer found a high spot in the window surround that put the glass under stress as it was installed. All it took was a warm day, in direct sunlight, to shatter the glass. It happens!
Let's not automatically assume that the vehicle owner is at fault here. Older car, maybe. But a new car.......?
