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.

FUEL/PROPULSION SYSTEM, ENGINE
My 2020 Mercedes-Benz A220 experienced the same defect described in NHTSA Recall 21V961000 (fuel injector leakage and potential fire hazard). In March 2023, my vehicle was diagnosed with leaking fuel injectors that were causing fuel to leak back through electrical connections, creating circuit issues and a fire risk. I paid $2,902.65 out-of-pocket at a certified service center to have all four OEM fuel injectors replaced (invoice available). Later, I took my car to a Mercedes-Benz dealership, where they performed additional work on the fuel injector system at no cost to me. The service advisor stated that this was covered under a recall/service campaign related to the fuel injector defect. This shows Mercedes-Benz has already acknowledged that my car was affected by the exact same issue covered under Recall 21V961000. However, I was told my VIN [XXX] ) is not officially included in the recall population, and Mercedes-Benz USA has declined to reimburse me for the $2,800+ repair. I believe my vehicle should have been included in the recall population and request that NHTSA review whether the recall scope should be expanded. I also request reimbursement for the repair costs I incurred prior to Mercedes-Benz performing the recall-related fix for free.

ENGINE, UNKNOWN OR OTHER
My 2020 Mercedes-Benz A-Class has experienced a recurring and extremely dangerous transmission malfunction beginning around 15,000 miles and continuing through 75,000 miles. While driving on both highways and main streets, the car would suddenly stall and shift itself into neutral. A warning message would appear on the dash saying “Cannot reverse – take to dealer.” The gas pedal would become unresponsive, and although I would try to shift back into Drive, the car would not move. The vehicle would slowly lose power and come to a stop in the middle of the road/highway, leaving me completely stranded in traffic with no safe way to move the car. On one occasion, I panicked while stopped in the road and attempted to switch into manual mode with paddle shifters and back to Drive — this briefly worked and allowed me to coast to a safe location. However, on the most recent and most dangerous incident, the car showed cannot reverse take to dealer the switch to “Transmission Malfunction – Stop Vehicle” and no tricks worked. I was stuck in traffic on the highway,for a few minutes unable to drive, until I turned the vehicle off and on multiple times, after which it allowed me to shift back into Drive and exit the roadway. Experiencing the worse anxiety I’ve ever felt in my life as I was just thinking I was going to get hit at full speed and die. This issue has happened multiple times and created life-threatening situations every time and emotional stress. Mercedes-Benz has acknowledged the defect by approving a manufacturer buyback, but the defect has never been fully repaired as of yet. My car is still at dealer. I am filing this complaint to alert NHTSA of this recurring and unsafe issue in the 2020 Mercedes-Benz A-Class. Other drivers may experience the same malfunction, and this could result in serious accidents or fatalities if not addressed through investigation or recall.

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.

POWER TRAIN
The drivetrain/shaft is causing rumbling in the vehicle when accelerating and decelerating, typically around highway speeds. after more investigation the parts used on the a220 were also used on the gle350 that were recalled for having the same issues however the a220 wasn’t recalled for those issues.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
While driving my lease vehicle on two separate days, it completely shut down while in motion with no prior warning. The first incident occurred while crossing a MAX train intersection in downtown Portland. The engine stopped mid intersection, emitted a strong mechanical odor, ticking noises began, and dashboard alerts appeared. I could not restart or shift the vehicle into neutral. It was stuck, blocking the intersection. Although hazard lights were flashing, the vehicle appeared completely undamaged, so other drivers didn’t realize it was disabled. Police were called to the scene, and we had to remain alert for oncoming trains and traffic weaving around us. Four days later, while driving about 30 MPH on Murray Boulevard near Cornell Rd, a 4-lane hwy near a freeway off-ramp the car failed again in the exact same way. The engine shut down in active traffic. The smell, ticking sounds, and dashboard messages all returned. The vehicle once again would not shift into neutral or respond to restarts. This failure happened with traffic traveling 30-45MPH. Despite police presence and hazard lights, multiple near-accidents occurred because the vehicle looked fully intact and other drivers didn’t understand it was inoperable. Mercedes-Benz claimed this was a starter motor issue, which is inaccurate. A starter motor does not cause a moving vehicle to shut off, nor does it lock out neutral. These symptoms point to a critical failure of the powertrain or electrical system. Most alarming is the inability to manually override the system and move the vehicle to safety. Bystanders and even police were unable to shift or push it. This is a serious design flaw that turns a technical malfunction into a dangerous roadside emergency. This vehicle was in pristine condition with no damage or misuse. I kept up with all maintenance and care. Technology should never prevent human intervention during failure. These incidents placed lives at serious risk.

The rear camera is experiencing failure. It blacks out when reversing and I'm unable to see my surroundings. There is an active recall for my vehicle year, make and model, but for some reason my VIN isn't listed as active? The dealership has acknowledged that my vehicles issues are the same as the recall issues. Could you please assist with getting my vin added to the recall list. Thank you

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.

The contact owns a 2019 Mercedes-Benz A220. The contact stated that while driving at an undisclosed speed, the vehicle briefly began to shake and vibrate violently, after which there was an abnormal odor inside the vehicle. The vehicle returned to normal functionality, but the failure became a regular occurrence. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed failures with the fuel injectors and the crankcase ventilation system. The contact was provided the following OBD codes; P1CEF85 and P1CE577. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V961000 (Fuel System, Gasoline); but the VIN was not included. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 59,000.

The car shakes, vibrates and has rough idling. My engines stalls when it is at low rpm. I am afraid that if this is not fixed a fuel leak could occur in the presence of an ignition source, such as hot engine or exhaust components, which could increase the risk of a fire

I was driving and I got coolant error on my dashboard. It came and then off. I pulled over and nothing seemed wrong with my engine. I restarted and headed home. The error was still on but the car was driving fine. I was trying to make it home. The car suddenly had all sorts of errors. It told me that my car was undrivable. I had no control over my car going 55 mph on a highway. I was luck to steer the car to the side of the road. Even when I was on the side of the road, I could not put it in park. It kept telling me my car was in danger of rolling away. I had my husband come meet me on the side of the road and he parked behind me so that my car did not roll away. I was on a slight incline on 32. We then waited for a tow truck. During that time, I tried to restart my car - only for it to give me undriveable, blind spot assist inoperative, errors. I could remember all of them. The tow truck guy had no idea what was going on either. My car spent 22 days at the dealership. It took them days to figure out what might be going on. Obviously the PMC module was bad. But why? They think condensation or leak from the AC hose had caused this problem. They found corrosion on the wire harness connector to PCM and on the PMC pins. They replaced the PMC and cleaned the pins. They got the car running - however, a week later, the same issue started happening. Now my battery said is was not charging. We figured it was time to change the battery anyway but it still will not turn on. I just had a full 50k service complete at this dealership in May 2024 There may be further damage to the system that the dealer realized. My car still does not run and I don't feel safe driving it when I can power it up.
