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.

- What is wrong
- 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.
- Risk
- 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. This will be a phased campaign, with the remedy becoming available in different phases based on model and model years. Owners may contact MBUSA customer service at 1‑800‑367‑6372. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on beginning July 31, 2026.
