Vehicle: 2020 Mercedes-Benz GLB 250 4MATIC Current mileage: Approximately 109,000 Date of most recent major incident:XXX I am reporting serious, recurring safety concerns involving my 2020 Mercedes-Benz GLB 250 4MATIC, including engine malfunction, loss of acceleration, repeated overheating, misfire warnings, and intermittent electronic display failure. I purchased this vehicle Certified Pre-Owned in XXX with approximately 44,000 miles. Since purchasing it, I have experienced multiple significant mechanical failures despite repeated Mercedes-Benz dealership repairs. SUMMER 2024 – REPEATED OVERHEATING ON [XXX] While traveling on [XXX] in [XXX], my vehicle began overheating. I contacted Mercedes-Benz and was advised that I could continue driving. The vehicle repeatedly overheated, requiring me to pull onto the shoulder of the interstate multiple times to allow the engine to cool before attempting to continue. I was traveling away from home and ultimately required assistance from another individual who picked me up and provided somewhere for me to stay. I believe this incident placed my personal safety at risk because I was repeatedly forced to stop along an interstate due to an overheating engine. The vehicle was subsequently taken to a Mercedes-Benz dealership in [XXX], for repair. XXX – ENGINE MISFIRES AND MAJOR ENGINE REPAIR While traveling in [XXX], the check-engine light illuminated intermittently. After returning home, the warning returned. I was advised of ignition/misfire problems involving cylinders 1 and 3. Mercedes-Benz subsequently performed significant engine work, which was described to me as replacement or repair of ignition components and the upper portion of the engine. I was told this involved a known manufacturer issue. During the same service, Mercedes-Benz identified an oil leak involving the oil-filter housing and perform- I have more INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.
