2015 MERCEDES-BENZ AMG GLA45 Complaints
On the morning of April 28, 2026, at approximately 7:30 AM, I discovered that the front panel of the panoramic sunroof on my 2015 Mercedes-Benz GLA45 AMG had spontaneously shattered while the vehicle was parked at my residence in Meridian, Idaho. When I went out to the vehicle in the morning, I found glass fragments distributed across the rear seat area, the rear floor, and my child's car seat. Looking up, I saw that the front panoramic glass panel had shattered. My husband and I conducted a complete walk-around inspection of the vehicle exterior. We found no evidence of any external impact: no damage to the roof surface, body panels, surrounding trim, or any other glass on the vehicle. There was no debris (rocks, branches, hailstones, construction materials, or any other potential impact source) on top of, beneath, in or around the vehicle. The rear panoramic glass panel was intact. Glass fragments were present both inside the cabin and on the exterior surface of the roof and a few fragments were found on the roadway. The car seat where glass fragments fell is regularly occupied by my [XXX] daughter. On this particular morning, she was not in the vehicle only because of a coincidental change in our family's schedule that day, but typically she gets into her carseat independently, buckles herself, and I check her buckles. Thankfully, she was not injured but her car seat now has glass fragments in the seat. I am filing this complaint to document the incident in support of NHTSA's ongoing collection of safety data for consumers.
