AIR BAGS, ELECTRICAL SYSTEM
Subject: Recurring SRS Warning and Driver’s Knee-Airbag Fault — 2019 Mercedes-Benz A220 I am reporting a potential safety concern involving the Supplemental Restraint System (SRS) in my 2019 Mercedes-Benz A220. The vehicle developed a recurring SRS/airbag warning. Mercedes-Benz identified diagnostic trouble code B000411, described as a driver’s knee-airbag squib short circuit to ground. During the initial visit, the dealership inspected and reinstalled the component. The warning subsequently returned. The dealership later recommended replacing the driver’s knee airbag, with an estimated repair cost of approximately $3,600. I am concerned that a recurring fault in the airbag system could affect the vehicle’s ability to provide intended occupant protection in a crash. I have contacted Mercedes-Benz Customer Care and filed a complaint with the California Bureau of Automotive Repair. I respectfully request that NHTSA review this reported safety issue and determine whether it may indicate a safety-related defect affecting other vehicles. Vehicle: 2019 Mercedes-Benz A220 Diagnostic code: B000411 Repair estimate: Approximately $3,600 I can provide dealership records, diagnostic information, and correspondence upon request.

ENGINE
I am filing a vehicle safety complaint regarding my 2019 Mercedes-Benz A220 equipped with the M260 engine. While driving on a public street, my vehicle experienced an unexpected loss of engine power and stalling. The engine also exhibited significant shaking, misfiring, and activation of the check-engine warning light. The unexpected loss of power while driving created a dangerous situation because I could have been involved in a collision with another vehicle. I was extremely concerned for my safety and the safety of other motorists. My mechanic subsequently diagnosed the vehicle with a cylinder head failure and advised me that continuing to drive could be dangerous. Because of the seriousness of the mechanical problem and the safety risks involved, I had the vehicle repaired. The repair cost approximately $3,800 and was performed by an independent mechanic using genuine Mercedes-Benz parts purchased from an authorized Mercedes-Benz dealership. I later learned that Mercedes-Benz had reportedly extended warranty coverage for certain M260 engine cylinder head failures to 15 years or 150,000 miles. I am concerned that other Mercedes-Benz vehicles equipped with the same engine could experience similar failures, potentially resulting in unexpected engine stalling or loss of power while driving. I respectfully request that NHTSA investigate whether this cylinder head failure represents a broader vehicle safety defect that could endanger drivers, passengers, and other motorists.

ENGINE, POWER TRAIN, ELECTRICAL SYSTEM
As of June of 2026 i witnessed my thermostat gauge going from cold to Hot in a back and forth motion. This rising in temperature on the thermostat gauge has happened during acceleration above 45mph, sitting idle with AC on, and while sitting idle after only about 10 mins of car being powered on and in motion. Because the vehicle is under warranty i believed parts would be replaced with new parts but as of today August 11th, 2026, the problem continues and has now been reaching the hot meter on the thermostat gauge. I have sent my car back to my dealer 3 times in a month in a half with the same issue happening repeatedly. Following the second repair period my car stopped unlocking on and off for the days following and now that has been upgraded to a recall issue which was not fixed or truly given any attention at all. This has put me in a hardship position and has not been attended to properly from the first repair. I have In real time recordings of this issue as evidence and am needing some assistance on this matter. I also have the invoices of both repairs which show that no repair was done to the actual affected areas of my vehicle instead they worked on parts that were not of concern.

I was driving home from work down the hwy, when the sun visor shade fell down and hit me in the head and covered my face, temporarily blinding me, like a blanket was pulled over my face. It's very difficult to see the road or other drivers when you are blinded at 70mph! Car only had 15,500 miles on it...

ENGINE, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, SERVICE BRAKES
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.

FUEL/PROPULSION SYSTEM
While driving the car shuts off and unable to restart. It will turn over but not remain started enough to move the vehicle. I did notice it jerk when speed was increased a few times before. Fuel pump was replaced less than a year ago according to Mercedes in Tuscaloosa Alabama. . After a certified Mercedes mechanic inspected the vehicle I was told it was the fuel pump once again. $4000+ later and I am having the same issue. Very frustrating to be stranded with my kids in the car.

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
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.

The tow hook and strap used when necessary to tow a car and that is stowed under the car or behind the rear bumper and accessed through a small door on the bumper spontaneously deployed while I was driving. It flew up against the side of the car, causing minor damage, damaged and partially dislodged the rear bumper, and the hook embedded in the right rear tire, causing it to go flat. I am waiting to learn whether there is additional damage to the underside of the car such as to a brake line. The parts are available for inspection. This is not a problem to be reproduced! I have photos showing the car and the hook in my tire. The only warning light appeared after the tire started losing pressure, but the thump sound as the hook and strap hit my car, and as the tire rotated and drove over the hook alerted me first. The weather was clear, there was no immediate traffic, no obstacles in the road. No sign of a bullet or something to cause it to deploy.

ELECTRICAL SYSTEM, VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM, BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
The component or system that failed was the MBUX Hard Disk Drive (Part#: A0009062711). My car is available for inspection upon request. My safety and the safety of others were put at risk because when the MBUX Hard Disk Drive malfunctioned the following happened: 1) The defogger was spontaneously disabled hindering the driver's view of the road 2) The rear camera was spontaneously disabled while in active use of reversing the car risking hitting someone or something 3) Content from Satellite radio some of which was vulgar language would spontaneously blast through the car speaker on the highest volume causing the driver to become alarmed/distracted from the road with the inability to power off, mute or lower the volume because the volume, mute and power off button for the radio would malfunction. This incident caused me to slighty loose control of wheel because I was caught by suprise or shock of loud music or content coming through the speaker uninvited. Lastly, in the year 2021 a recall/remedy for this component was to be replaced by Mercedes Benz on other specific models. I do not understand why my vehicle was not added to the list of cars that required a remedy. I should NOT had to learn and experience similar impairments 3 years after a known issue. I should had been made aware of this defective part 3 years ago.
