“I was driving with no other cars around, and i heard what sounded to be an explosion, come to find out my sunroof had exploded. I had glass fly all over the back windshield, and onto the road behind me. This could have caused an accident or damage to other vehicles if someone was around me.”

“My sunroof exploded while driving on Lakeshore drive. I hear a loud boom and I almost crashed. I thought it was my tire or something else look up its my sunroof, I could have hit some one or hit something. It hasn't been inspected or anything as of yet it just happened at 6:30am. This is crazy because there was no warnings no cracks no anything. I ride with my sunroof cracked open every morning. so I don't understand.”

“7/20/26 My 17 year old daughter was on the way to work and heard a loud noise like an explosion in her car. She, new to driving, scared and in a panic just assumed this was a blowout on a tire and pulled over to check the tires. All tires were clear so she proceeded to work cautiously, on her way home she noticed her check engine light had come on and noticed there was some road noise coming from the back. She then called me, note this is the first I heard of the situation. …”
