The vehicle was operating normally the previous night. We drove it and parked it in the driveway that evening, and it was not used again after that.

26V481000 · Latches/Locks/Linkages:Doors:Lock
Reported: 2026-07-24 (July 24, 2026)
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: 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.
