  1. Filed Mar 11, 2026Failure Mar 6, 2026Washington, DCFuel/propulsion system

    To Whom It May Concern, I am writing to file a formal safety complaint regarding my 2019 Mercedes-Benz CLA250 involving a leaking fuel rail that caused the vehicle to shut down and become unsafe to operate. The failure of the fuel rail resulted in a fuel leak and engine shutdown. A failure within the fuel delivery system presents a serious safety concern, as it can cause sudden loss of power while driving and poses a potential fire hazard if fuel comes into contact with hot engine components. During the repair process, I was informed that the necessary replacement component, Fuel Rail Part Number 2700701995, is no longer being produced by Mercedes-Benz. Because this critical component is unavailable, the vehicle cannot currently be repaired and is therefore undrivable. It is deeply concerning that a safety-related fuel system component for a 2019 vehicle is no longer available. Without access to this essential part, the vehicle is effectively disabled. Additionally, based on the nature of this failure, I believe this fuel rail defect should be included in the recall list for this vehicle. A leaking fuel rail capable of shutting down the engine represents a significant safety risk that may affect other vehicles of the same model. I have attempted to contact Mercedes-Benz Customer Care at [XXX] on seven separate occasions and have left messages requesting assistance, but I have not received a return call. Because this issue involves both a serious fuel system failure and the inability to obtain a critical replacement part, I respectfully request that the National Highway Traffic Safety Administration investigate whether this defect affects other 2019 Mercedes-Benz CLA250 vehicles and determine whether a recall is warranted. Vehicle Information: Year: 2019 Make: Mercedes-Benz Model: CLA250 VIN: [XXX] Part in Question: Fuel Rail – Part No. 2700701995 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    The sunroof is off the track. There seems to have been a recall for my make and model and year of vehicle (2019 Mercedes CLA 250) though Mercedes tells me that my vin # is not among those that were recalled. However, they told me that if I could reach out to NHTSA, that it would be possible that my vehicle would be added to the recall, which would force Mercedes to have to repair the issue at their cost, so this is me doing that.

    My 2019 Mercedes-Benz CLA 250 has become unsafe to drive due to strong gasoline fumes filling the cabin. The smell is overwhelming and makes it difficult — and frankly dangerous — to sit in the vehicle for more than a few minutes without feeling lightheaded. I have since learned that this issue is part of a known defect covered under NHTSA Recall #21V961, which affects 2016–2020 CLA 250 models for a fuel leak and potential fire hazard. Despite the recall directly describing this exact problem — fuel vapors entering the passenger compartment — I was told that Mercedes-Benz will not cover the repair costs, even though the recall was never performed on my car. This is deeply concerning, as gasoline fumes inside the cabin pose not only a serious health risk from inhalation but also a potential fire or explosion hazard. It’s unacceptable that a manufacturer would refuse to remedy a safety recall issue, especially one involving a known fuel system defect that could endanger both the driver and passengers. I’m left with a car that’s unsafe to drive and a manufacturer unwilling to take responsibility for a problem they’ve already acknowledged through the NHTSA.

    Fuel lines, strong gas smell inside the cabin, the gas leak posed a significant safety hazard, risk of fire or explosion, risk of carbon monoxide poisoning, risk of injury or death to myself and/or others.

  10. Filed Aug 14, 2024Failure May 15, 2024Saint Louis Park, MNEngine

    Although I bought this 2019 Mercedes Benz CLA 250 less than 1 year ago with 18,600 miles on it, in May 2024 the check engine light came on and the dealer service shop gave the following diagnosis: CRANKCASE VENTILATION HOSE. Comments: THE CRANKCASE VENTILATION HOSE HAS AN INTERNAL FAILURE AND IS CAUSING THE CHECK ENGINE LIGHT. THE CRANKCASE VENT HOSE IS NEEDED TO BE REPLACED. Repair Estimate: $1769.00 They told me that it is a known issue and that many other models have been recalled, but because my exact make, year, and model was not yet included I would have to pay out of pocket. This seems wrong since the issue is so prevalent among Mercedes models that there is a national backorder on the part with no definite end. When I reached out to Mercedes about this, they were unwilling to do anything. Please make them add it to the long list of models that have received recalls/extended warranty for this!

    The rims of the Mercedes continually crack with moderate low speed driving. Has happened 4 to 5 times with under 50,000 miles, leaving me with constant flat tires, once on the George Washington bridge and once at night in a deserted area with zero warning. Luckily, I was able to remove my vehicle to the side. I was towed to Mercedes and they suggested changing out all 4 tire rims without a warranty as will happen again. VERY EXPENSIVE. The coupe models have this problem after 2019. Material for rims came from China, not Germany. I found a good rim repair shop and have done 4 times. He said he gets these all the time and there can be no warranty as the design of the tire and rims is flawed. 175.00 per rim. Mercedes of 2019 and forward as well as BMW's of this model (a Coupe) have this as recurring problem so no warranty on the work. Clearly a materials, manufacturing defect that Mercedes won't own.. I carry a Ryobi blower in the car and have to blow up my tires every morning which deflate every night.!! Crazy

    I HAVE HAD THIS VEHICLE FOR A YEAR AND A HALF AND I DON'T DRIVE IT MUCH. THE VEHICLE HAS 12,000 MILES ON IT AND I'M A VERY CAREFUL DRIVER. I VERY RARELY HIT ANY POTHOLES AND HAVE NEVER BEEN INVOLVED IN AN ACCIDENT. AFTER MY TIRE KEPT LOSING AIR, I TOOK IT TO THE DEALERSHIP TO FIND OUT THAT NOT ONLY IS ONE OF THE RIMS CRACKED BUT THE OTHER THREE RIMS ARE BENT. I HAVE NO IDEA HOW THIS COULD HAVE HAPPENED, CONSIDERING HOW CAREFUL I AM AND THAT NO ONE ELSE HAS EVER DRIVEN MY VEHICLE BEFORE. I STRONGLY BELIEVE THAT I WAS SOLD A VEHICLE WITH DEFECTIVE WHEELS AND THROUGH RESEARCH, I SEE THAT MANY OTHER CLA OWNERS ARE EXPERIENCING THE SAME ISSUES. THESE WHEELS COST ABOUT $1,000 EACH TO REPLACE AND HAVE THEM INSTALLED BY THE DEALERSHIP AND THIS IS NOT ONLY VERY COSTLY BUT DANGEROUS FOR MERCEDES TO CONTINUE MAKING.
