Driving home mid morning Thursday , March 5, 2026 on smooth paved rural road, 50MPH, sunny, temp was 40 degrees, no vehicles anywhere near us, our Panoramic Sunroof shattered on our 2013 Mercedes GLK 250. We heard a loud "BANG", but had no idea what it was. I slowed down, pulled over and while looking up, I noticed the sunroof had completely shattered and cracks were spreading as we sat watching it. I drove home short distance and parked the GLK in the garage. There are no visible signs of an impact to the glass exterior nor interior. To keep it from falling into the cab, I taped the inside and outside with clear packing tape. The vehicle is out of warranty and we don't have comp nor collision on it anymore due to it's age. While researching for glass replacements, I found that there are numerous Class Action Lawsuits for this issue. This is a very dangerous defect and safety issue as when the glass shattered, it was as loud as a shotgun blast and very unnerving. The vehicle is currently undriveable and unsafe.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
