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.

I have had numerous issues with my 2019 A220. At 92k mi my cylinder head had to be replaced. My check engine light came on and they said there was a cylinder head leak. At 108k miles I had to have it replaced yet again because my car lost power driving uphill when shifting between 4th and 5th gear. Now at 112k mi the check engine light came on and sure enough they need to replace all 4 ignition coils… Additionally, I have issues with my air vents. They will frequently send air out of a section I have turned off (ex. turn air on my upper body and it sends air to my feet instead). Somewhat related but whenever I turn my car off it makes a lot of strange noises on the inside of the car by my entertainment center, almost similar to a stomach grumbling/farting noises. Lastly, I’ve had issues with trying to close my windows and they’ll close fully but then drop down half an inch or so afterward.
