Defect. 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. 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.

My 2021 Mercedes-Benz A220 (M260 2.0L engine) triggered diagnostic fault code P052E, indicating a failure of the Positive Crankcase Ventilation (PCV) regulator valve / intake line assembly. Failure of this valve disrupts crankcase pressure, causing unmetered air intake, lean-running conditions, and engine hesitation/stalling risks. Mercedes-Benz issued a 15-year/150,000-mile extended warranty campaign for this exact PCV failure on M274 engines, but has excluded M260 engines despite identical failure modes. The manufacturer has not remedied this known design defect, creating potential drivability and engine pressure hazards.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
