I was driving about 60 miles per hour on the highway around 3:00 pm on a weekday and my sunroof just shattered into thousands of pieces, it sounded like a gunshot when it broke. i swerved into the next lane, nothing happened but this incident could of been a lot worse. at the time no one else was on the highway so it couldn't have been a rock or something else that may have caused this to happen and regardless of the triple digit summer texas weather the glass was suppose to be heat tempered. i had to pull over because chunks of glass started to fly off and was hitting the back of my trunk, scratching the paint job.
