Body & structure
As I was driving today in the freeway my sunroof exploded. As far as I can tell, It was not caused by rocks or other cars, it just exploded putting my wife and I in a dangerous situation having to park on the side of the freeway. We first thought someone shot at us. We stopped the car and it took us a minute to feel safe to go out, trembling, to check car for gun fire. We looked the entire body while the freeway was full, even for a Sunday, and discovered nothing wrong. As we entered the car and closed our door, we heard the noise of shared glass, so we both left the car again to reinspect it putting our lives in danger as other drivers were passing by. We re-enter the car again and the same thing happened, left the car again to inspect the tires at this time, each time exposing our lives to the freeway traffic. …
