Three months after having a new windshield installed in my Volvo, the new windshield cracked as well. Coincidence? Maybe - but I was driving the car and did not hear or see any impact. The technician came out to look at the windshield, and said it must have been hit by something on the edge of the windshield - even though there was no impact mark - no warranty, so sorry. I can tell you they won't be getting my business for the replacement replacement.
