I had just exited onto the highway and had not even made it to the next exit ramp, when my sunroof exploded. it sounded as if a gun shot had gone off in my car. we were hit with shards of glass as the glass did not shatter into small pieces. glass pieces were 1+ inches long and 1+ inches wide. we had no vehicles next to us. we did not find any debris in the car or on the roof of the car except for shattered glass.
