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 hood-latch sensor fault and its interaction with the windshield-wiper controls, including whether an erroneous hood-open signal can disable the wipers while driving and whether other vehicles may be affected. This requires urgent attention because the unexpected loss of an essential visibility function while driving creates a serious danger to me and everyone sharing the road.

Jul 24, 2026

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.

Consequence & remedy

Consequence: 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.
