Side/rear Glass problems of the 2010 Honda FIT

I was sitting in the parked car listening to the radio before work when I saw a foot long crack form half way up the right edge of the windshield horizontally toward the center of the windshield. There was practically no people or cars around and it was a clean straight line crack. I found an online forum on edmunds. Com where there were many people having stress crack issues with their Fit windshields. I went to the dealer and they found a chip in the crack about the size of a pinhead, 2 inches in from the edge of the windshield. They claimed a stone hit the windshield to cause the chip and suggested contraction expansion of the glass caused the crack. They refused to cover the damages under warranty. A phone call to Honda automobile customer service claimed no reports of issues with Fit windshields and also refused warranty coverage even after mentioning the online forum.
