Latches/locks/linkages:doors:lock
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.

Problem: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2023-2026 EQE and GLC vehicles. Please see the recall report for a complete list of models. The steering coupling bolt may have been improperly tightened, allowing the steering coupling to loosen from the steering rack.
Risk: A loose steering coupling can cause a loss of steering control, increasing the risk of a crash.
Fix: Dealers will tighten the steering coupling bolts as necessary, free of charge. Owner notification letters were mailed October 6, 2025. Owners may contact MBUSA customer service at 1-800-367-6372.
Exterior lighting:headlights
Problem: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2023 GLC 300 and GLC 300 4MATIC vehicles. The headlights are missing adjustment prevention caps, which can allow the headlights to be improperly adjusted. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: Improperly adjusted headlights can reduce visibility, increasing the risk of a crash.
Fix: Dealers will inspect the headlights for sealing caps and install caps as necessary, free of charge. Owner notification letters were mailed July 18, 2025. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2025060005.

In certain crash scenarios, where the rear occupant's head contacts the C-pillar, the pillar may not absorb an adequate amount of the impact. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 201, "Occupant Protection in Interior Impact."
Risk: In the event of a crash, insufficient impact protection can increase the risk of injury.
Fix: Dealers will modify the roof lining and C-pillar trim, free of charge. Owner notification letters were mailed July 9, 2025. Owners may contact MBUSA customer service at 1-800-367-6372.
