Last summer, i was washing the rig. As soon as i rinsed water on the windshield, it cracked right in front of me. From the lower molding to the top within seconds
I thought for sure it was a defective windshield because i couldn't find any stone chip. So i brought it to the dealer trying to get it fix under warranty. And the GM rep just happens to be there that day. First he look and couldn't find any visible damage then he used a ball point pen and traced the chip at the very bottom of the windshield, right on top of the lower molding
Then told me sorry pal, can't cover it under warranty...
Also, beware dealer doesn't always use genuine GM parts. This dealer charged me $500+ (which i thought wasn't too bad at first for a genuine GM part and the fact it was the dealer so i expect to pay more) but when i pick up the H, the new windshield had a big old PPG logo right in the middle! Long story short, had them take it out and put a genuine GM windshield on it. Final bill was $900+
