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.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“When driving tried to give it gas/accelerate and it stalled, jerks/chugs hard with no warnings. Then after the chugs stop when trying to give gas there is no response. Acts like the transmission is in protective mode. The motor is still running and was able to coast however when trying to accelerate there was no response. Had to pull to side of road. I was able to turn it off and back on and seemed to act normal again. It acts like the current recall of NHTSA#23V445 on all the other models in same years. The check engine light did come on steady and it has the following 3 codes when checked P008A low pressure fuel, P1463 gas and P0087 fuel rail system pressure low. I called the dealership and am taking it in tomorrow to drop off for them to inspect on Monday and they believe those codes are still covered under warranty. They offered a rental to use until looked at and fixed.”

Background of Failed Repairs My vehicle has already spent 15 cumulative days out of service for an ongoing engine defect. An authorized Mercedes-Benz dealership recently diagnosed the vehicle and performed a major cylinder head assembly job/replacement to resolve engine misfires and a persistent Check Engine Light. This defect is well-documented by Mercedes-Benz under its active 15-year/150,000-mile extended warranty program for the M260 engine cylinder head. The Critical Safety Incident…”
