Worst place to hit, right on the edge. My Chrysler 300C went the same way. Minor hit but a half inch from the edge, crack worked it's way straight across. Much bigger hit right in the middle never cracked.If this was a big impact I would understand and would not have even posted. I have a rock chip in my accord that hit so hard it sounded like a shotgun was fired inside my car. This issue is all that was heard was a small ping of the glass breaking and I had to get out and inspect the crack before I could even find the "impact" mark, which once again was not even big enough to put a pen tip into.
