Well, It looks as if it broke at the frame. There is about 10 cracks (6 in or so from top to bottem of where they start) that all come together and form one large crack about 6 inchs into the windsheild. The opne large crack then move about another 6 inches or so. There also looks like there are many tiny hairline cracks between the saftey glass. Before I took the car in, I did as you said to ensure there was no chips ect. that I could feel. Theres not. I took it back to the dealer where I purchased, this is the same dealer that told me 3 times there was nothing wrong when I had a timming issue. I have contacted the 1-800 GM number and am awaiting feedback.
