Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Was driving vehicle on freeway, around 65 mph, smooth road, no bumps, no indication of any road debris and suddenly heard a loud cracking/exploding noise which was extremely startling. After hearing some outside wind noise and the sound of glass pieces rattling, I realized that the glass panoramic sunroof must have broken somehow. Luckily I had the interior fabric shade closed, so no glass pieces entered the cabin to injure anyone. After getting out of the car, I could see around a 12 inch diameter hole in the sunroof glass. The remaining glass that was still attached was full of cracks. …”
