What owners report most
Structure
“I was driving down the highway at 70 mph and it was windy at the same time. Out of no where my sunroof window exploded shattering the glass. Luckily I usually keep the cover close. It sounded a gun shot that went off. There was nothing around me that would come down and break the window of the sunroof. It just happened out of no where.”
