The sunroof spontaneously exploded causing shattered glass to fall on the driver while driving down the highway. It sounded like a gun went off. There was not any debris or rock that could have caused the shattered glass. The glass was lifted upward, not downward as would have been the case if something came from the sky or air. The temperature was 55 degrees Fahrenheit and the time was approximately 3:40. I had used the sunroof earlier in the morning without a problem and never had a problem before.
