While driving, the panoramic sunroof on my 2020 Mercedes-Benz CLA250 4MATIC shattered unexpectedly while fully closed. The interior sunshade was also closed at the time. There was no prior damage and no discernible impact. I did not observe or hear anything strike the vehicle. The fracture pattern shows no identifiable point of origin or impact and appears irregular and multi-directional, which is inconsistent with external debris. This appears to be a spontaneous tempered glass failure and raises safety concerns due to the risk of injury to occupants and driver distraction while operating the vehicle.
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2020-2021 CLA, 2019-2022 A-Class, 2022-2023 C-Class, 2024 CLE, 2020-2026 GLA/GLB, and 2023-2024 GLC vehicles. Please refer to MBUSA's recall report for specific model information. The micro-switch in the driver's door lock may corrode and fail to detect an open door, preventing the electronic parking brake or "Auto-Park" feature from engaging automatically. This may result in a vehicle rollaway.
Consequence & remedy
Consequence: A vehicle rollaway increases the risk of a crash or injury.
Remedy: Dealers will replace the driver's door lock, free of charge. Owner notification letters are expected to be mailed September 18, 2026. Owners may contact MBUSA customer service at 1-800-367-6372. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning July 31, 2026.
