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.

Visibility/Wiper
Filed Sep 14, 2026NJ

My 2020 Mercedes-Benz GLB has a serious, unresolved safety issue involving the hood-latch warning and windshield wipers. While I am driving, the hood-open warning appears and the windshield wipers cut in and out or shut off unexpectedly. This problem was already occurring by March 2026. The vehicle currently has approximately 85,000 miles. During the recent heavy rain in New Jersey, these interruptions have compromised my visibility while the vehicle was moving. When the wipers stop clearing rain, my ability to see traffic, pedestrians, lane markings, and roadway hazards is impaired. This can prevent me from recognizing danger and reacting in time, putting me and other road users at immediate risk of a serious collision. I am concerned that this recurring failure could cause serious injury or death. A Mercedes-Benz dealership inspected the vehicle and diagnosed an “internal failure of hood switch.” A Mercedes-Benz technician also told me that the windshield-wiper issue was tied to the hood-latch sensor. The switch was subsequently replaced, but the hood warning returned almost immediately after driving only a few feet. The warning and intermittent wiper shutdowns have continued despite that attempted repair. I have submitted a safety complaint to Mercedes-Benz USA requesting urgent attention and a permanent repair. The issue remains unresolved, and I cannot reliably depend on the windshield wipers to maintain visibility during rain. I am requesting that NHTSA investigate the

EngineFire
Filed Feb 10, 2026IL

The vehicle was operating normally the previous night. We drove it and parked it in the driveway that evening, and it was not used again after that. The following morning, we started the vehicle to allow it to warm up and then returned inside the house. Approximately 10 minutes later, we discovered the vehicle was on fire, with flames coming from under the hood. We immediately called 911. The fire department responded and was able to extinguish the fire; however, the vehicle was completely destroyed, and part of our home sustained fire damage. There were no prior issues with the vehicle. We had purchased it in September 2025, and it was in excellent condition. This incident could have resulted in far more serious consequences had it occurred while the vehicle was in motion or if emergency responders had not arrived as quickly as they did.

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.
