While driving at about 55mph on an open highway, the moon roof exploded. There was a loud explosion inside the car by my right ear. The noise was deafening and distracting and caused a momentary loss of concentration on driving, a situation that was very dangerous and could have resulted in an accident with serious injury. I immediately pulled over and checked the tires, the body and underneath the vehicle, finding nothing. When I began driving again, I heard a loud wind noise and other strange noises above me. I started to open the cover of the moon roof, but shards of glass fell on me, so I closed it again. Pulling over again, I climbed on the door threshold to look at the roof of the car. Unbelievable! It looked like a volcano with the glass pointing upwards around a big hole. Toyota Corp. is claiming it was caused by an outside source. That is definitely not true. I was in the car, nothing landed on the roof. The highway I was on has no bridges, no overpass, no multi-story buildings, no schools or no place that would enable someone to drop or throw a large item on top of a car. And, there was nothing on the inside cover except broken glass. The glass on the roof was definitely pointing upwards. The result of my research on exploding roofs shows that this problem has affected multiple car brands and multiple sun/moon roof manufacturers. I'm asking the NHTSA to help protect USA drivers. If there had been a warning that the roof could suddenly explode while I was driving, I definitely would have selected a car without a glass roof. If the cover had not been closed, I would have been sprayed with glass in addition to the loud blast. Because this is a major safety issue, I'm begging the NHTSA to look into the problem and at the very least immediately issue warnings so drivers of vehicles with sun/moon roofs will be aware that this could happen. It would be much better to find out what defect is causing this to happen before anyone is killed! The consumer stated he feels that moonroof exploding
