Went out to my car last night to drive home to find a 10" crack in the windscreen. It was parked in the carpark at work, with no possibility of it being damaged but it has broken. The crack starts form the very edge about 4" up one side and then goes around the tax disc and stops. I guess it will now spread in time. Could this be a fault with the fitting or screen that I could get done under warranty as there is no impact point at all, it just seems like something "gave up" and just cracked !!
