“Driving on 285 east in atlanta ga 11/29/2018 when my Lexus IS 300 sunroof exploded. All windows were closed temperature was 37 degrees. It sound like a gun went off. Glass fell from the roof and piece of the glass went in my left eye. I made appointment for the eye doctor for 11/30/2018”
NHTSA complaint #11154859, filed 2018-11, 7,000 miles“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.”
