“While driving on a local parkway, our sunroof spontaneously exploded. We were not passing under anything and nothing of any noticeable size struck the car or the sunroof. There was a very loud bang, and when we pulled over, we discovered a large hole in the sunroof. There were shards of glass sitting atop the sunroof cover, which had we not had closed, some of the glass would have fallen into the passenger compartment. A simple google search makes clear that exploding sunroofs are a real danger.”
