2019 Mercedes-Benz A 220: check engine light

Filed Oct 16, 2026 · Engine · FL

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 the federal safety agency investigate whether this cylinder head failure represents a broader vehicle safety defect that could endanger drivers, passengers, and other motorists.

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.

I have leased this vehicle from New in 2019. Since early 2020 I had the check engine come on as well as Tire Sensors. I informed Dealership and they took in for repair. My vehicle is repaired and handed back only for the check engine light and tire sensors to come back on. My vehicle has been in the service department for about 8 times and each time the check engine returns. No reason is given for the failure other than "bring it back and we will fix again". My check engine light is currently now back on and I have to return it again on Tuesday 7th Feb. It would have been in for repair more times but in 2020 I was told by the Dealership Service Manager at that time that it was safe to drive with the check engine light on..which I did. At this time I did contact MBusa and dealt with Executive Referral Manager [XXX]. I also contacted her again in 2022 for assistance. The Dealership can not fix the Check engine light as they have proved by the multiple failed attempts. They have has my vehicle in for weeks during my 42 month lease which ends on 30th March 2023. For nearly all this time the check engine light has been on I have recently again discussed this with MBusa and last week I was connected to another MB Executive Referral Manager called [XXX]. He confirmed that MBusa can not give vehicle mechanical or safety advice [which I found strange] as there is no department within MBusa that deals with this type of enquiry. He stated that whatever the Dealership sees as being safe then MBusa will stand by that decision. I have driven for nearly the whole of my lease with Check engine light on and tire sensor readings. I am handed back my vehicle with the assurance that it has been repaired only for it to fail .on one occasion within 2 miles drive from picking it up. Service Manager does not see this as an issue but I am totally unsure as to what the warning light is telling me and this has made me not enjoy my vehicle or to feel safe. Hence the reason it has 22k. INFORMATION Redacted PURSUANT TO THE FREEDOM OF I
