I had a small stone hit my windshield on a hot day and it cracked the whole windshield instantly. Had much bigger rocks hit my other vehicle and just chips...not full blown cracks. Seems like some issue with the volt windshields...
I respectfully disagree. The volt was the first windshield I've replaced in my lifetime and I've never had so much body work done to a car. My volt was prone to catching flying debris, for whatever reason (karma, aerodynamics, acts of God, blind luck). My 13 year old CTS doesn't even have a door ding on it.Yes, but not "Volt" specific windshield issues.
But once a crack starts, the OP is done for and would need to get a new piece of glass.6+ years, I have two small craters in the glass. Very very small. A glass shop can repair them, but so will a carefully applied drop of superglue. There are kits that have a smooth plastic film you apply to "cast" the curing glue as a flat surface so you don't end up with a pimple on the glass.
I once put a crack in the middle on the INSIDE of a windshield and watched that crack grow over the course of two years. Eventually it went from bottom to top. Winter cold on one side and cabin heat on the other will help it along...But once a crack starts, the OP is done for and would need to get a new piece of glass.
In other words they did the inspection I recommended and didn't find any chip in the windshield along the crack. It's possible it got chipped during assembly and the chip covered by the rubber trim. This would be a manufacturing flaw.It came from the bottom near the black part and goes about 4 inches into the clear part. Update: Wife took it to the dealer and they are going to replace under warrantee. They think it was some sort of stress crack unrelated to any impact. .
