Open the full vehicle complaint log (all categories)Vehicle: 2019 Mercedes-Benz A220 VIN: [XXX] Dealer: Mercedes-Benz of Walnut Creek (Walnut Creek, CA) I am reporting multiple safety defects involving federally regulated systems. The vehicle has repeatedly activated emergency braking at freeway speeds without reason, posing a significant risk of collision. The brake assist warning appears frequently, and both the front and rear proximity/collision sensors display a full red warning state with continuous audible alerts. These alerts cannot be cleared without manually disabling the safety system each time the vehicle is started. One of the sensors physically detached from the vehicle. Backup and parking assist features do not function correctly, and the vehicle repeatedly shows malfunction warnings. The dealer verbally stated that a “manufacturer-covered engine repair” was needed, but would not disclose the nature of the repair or whether it relates to these safety issues. After two weeks in their possession, the dealer refused to provide written documentation of any diagnostics or repairs performed. They attempted to return the vehicle without confirming whether it is safe to operate and threatened storage fees when I requested written confirmation. These issues involve systems covered under FMVSS 101, 111, 126, and 135, including electronic stability control, braking, rear visibility, and driver-interface warnings. The failures pose a clear safety risk to the driver and other motorists. I am requesting NHTSA review these defects for potential investigation or recall.
