It happened to me......another make of car: got it brand new, taking
delivery in January cold weather. The first warm day, I went outside
and the windshield was cracked from top to bottom.
The dealer was suspicious, but replaced it at no charge to me (they
probably made nice money for a warranty repair). It broke again a few
weeks later. Dealer replaced it.
When it cracked the third time, the manufacturer sent a factory crew to
replace it........don't know what else they did, but I know the dash
panel was removed and they acknowledged that the sheetmetal wasn't
right, stressing the glass. Looking back, I'm surprised they believed
me the first time. And first I ever heard that there were factory
repair crews that travel around taking care of weird problems.
