The car was parked and it was not in or near a street. Car was fine around 11am, by 7:30pm it had a circular break on the driver's upper windshield with a small knick. No stone or anything was ever found. I drove the car to work that morning. Nothing. Nothing ever hit that windshield. This is total bs. Luckily my insurance paid for it. But the kicker is that three months later it happened again, this time on the opposite side. And no one will do anything about it. My insurance company said if I claim it again, I will get disqualified. So sick of this piece of crap. It drives like a truck too. I will never get my a decent trade with a broken wind shield but who can afford to fix it, and why, so it can break again in another three months. I hate mazda now.
