2020 MERCEDES-BENZ Glb 250 4MATIC

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.

Complete engine failure mid driving on highway. NO engine light prior to complete engine failure. Vehicle has been towed to two different Mercedes Benz auto dealerships. Both service directors concur that this should not have occurred with zero warning and low mileage of 64,856 with an impeccable service record at Mercedes Benz Came on suddenly Julie 2026 and no engine warning lights
