2020 Mercedes-Benz GLB 250 4Matic recalls

Recall 26V-481: Latches/Locks/Linkages

Reported Jul 24, 2026 · 310,667 vehicles affected · Mercedes-Benz USA, LLC

Problem: 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.

Fix: 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 NHTSA.gov beginning July 31, 2026.
