Mercedes-Benz is recalling 310,667 vehicles in the United States after discovering that a fault in the driver’s door lock could prevent the vehicle from automatically securing itself when the door is opened. If the parking brake fails to engage as intended, an affected vehicle could roll away unexpectedly, creating a potential crash hazard.
What is the problem?
The recall covers several Mercedes-Benz models, including 2019-2022 A-Class, 2020-2021 CLA, 2022-2023 C-Class, 2024 CLE, 2020-2026 GLA and GLB, and 2023-2024 GLC vehicles, and the issue involves a microswitch inside the driver’s door lock. Moisture may enter the switch housing and cause corrosion, which can eventually prevent the vehicle from correctly detecting when the driver’s door has been opened.
That detection is important because the vehicle’s Auto Park and electronic parking brake functions may rely on the system recognizing that the driver has left the vehicle. If the door is not detected as open, the parking brake may fail to engage automatically, potentially allowing the vehicle to roll away.
Mercedes-Benz traced the problem to a supplier development issue involving the material used for the microswitch housing. The manufacturer was aware of 176 related field cases in the U.S., although no rollaway incidents had been reported when the recall was announced.
What owners should do
Owners of affected Mercedes-Benz vehicles should check their VIN through the National Highway Traffic Safety Administration (NHTSA) recall database to confirm whether their vehicle is included.
Mercedes-Benz dealers will replace the driver’s door lock at no cost to owners. Recall notices are expected to be mailed beginning September 18, 2026. Until the repair has been completed, owners should make sure their vehicle is securely parked and should not rely solely on the automatic parking brake function.
How Mercedes-Benz owners can take back control
A vehicle that may not secure itself properly when parked can understandably leave owners questioning its reliability and safety. For drivers who have already dealt with recurring faults, multiple dealership visits or other unresolved problems, another recall can add to an already frustrating ownership experience.
