2011 Mercedes-Benz C300: fuel leak

Filed Oct 23, 2024 · Acceleration, Airbags · TN

1.What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel system failure is a highly critical safety concern, and my life is at risk. It causes malfunctions with the vehicle, for example, the OBD-based emissions test has flagged a lot of (codes P219A, P0300, P0304, P0410, P0305, P0303, P0171, P0301) 5 of the cylinder misfire codes with the check engine light on, as well affecting other parts in the vehicle function properly, acceleration issues, car stalling as though it’s going to shut off. This is a serious matter and Mercedes-Benz is failing to prioritize customer safety, over cost especially when known faults in the vehicle can lead to potentially life-threatening incidents such as fuel leaks and fire hazards. Yes, the vehicle is available for further inspection upon request immediately each day my life is at risk. 2.How was your safety or the safety of others put at risk? My safety and other's safety are put at risk every time I get out on the road to drive my car it's putting me and other' live in serious danger (especially with the extreme increase in car accidents in the local Nashville, TN area). Despite the vehicle now being 3,000 miles over the 150,000-mile extended warranty threshold. I recently purchased the car on [XXX] and was not made aware of Mercedes Benz having any extended warranty coverage for the faulty fuel system that Mercedes-Benz had placed on this model. I can only assume the previous owner the car was reposed from was also unaware of this as well. I believe Mercedes-Benz should still cover the cost of this repair. The fuel system failure is a critical safety concern, and Mercedes-Benz should prioritize customer safety, especially knowing there were faults of poor quality that they discovered with their vehicles and can lead to potentially life-threatening incidents such as fuel leaks and fire hazards.

There is a crack in the flange causing a fuel leak in my C300 2011 Mercedes-Benz built March 2011. A strong gas smell fills the car. This situation is extremely dangerous and should be included in the recall that was approved for vehicles C300 manufactured from April 2011-July 2011. Please include my vehicle in this recall. There is only a one month difference.

My check engine light came on approximately one month ago. Once tested it indicated a fuel vapor leak. I pulled out of a driveway and a large stream of fuel spilled all over the roadway. Approximately 7 feet in length about 5 inches in width was on the road. I took it to a Mercedes repair shop and they informed me I had a fuel leak and that it was not safe to drive. There was corrosion and rust forming on the tank which seems very odd since the car is garage kept and we don't get much snow in Kentucky. My daughter rides in this car with me and they told me it is very dangerous and needs repaired. If I was to drive over a cigarette we could essentially blow up. I had a second shop look at it and they also informed me I had a fuel leak and would need to replace the fuel tank. I was told there was a recall on some models of Mercedes for this issue but can't seem to find one on my year make and model. Please help with this matter so my daughter and I can remain safe as well as others around us. Seems like we are in a ticking time bomb.

The subframe and the brake lines are very faulty in this car when it comes to its design. The subframe and brake lines rust easily and are cheaply made for this car. My car break down while driving making it hard to have pressure on the brakes. My incident was around the school area. There were no accidents or collisions Involved. It could happen to adults and children. The dealer never confirmed this problem before selling it to me. Another manufacturer told me about this problem. The car showed warning signs like the braking system and brake fluid. The brake fuel was leaking. The problem appeared when I started the car.

When fuel tank is greater than approximately 3/4 full there is a strong fuel odor that seems to emanate from the rear passenger side of the vehicle; at lesser fuel quantities the odor is not noticeable. On one occasion I detected what appeared to be fuel dripping from underneath the vehicle. Took vehicle to dealership for troubleshooting and was informed "fuel leaks at the fuel pump" and it was recommended that the fuel pump and fuel sender be replaced. Additionally, the leak apparently damaged the electrical wiring harness to the fuel pump and that also needs to be repaired. There were no warning lamps or messages displayed that alerted me to this problem. Obviously, this is a hazard to safety.

07/31/2021 Fuel smell in the cabin, and in the garage, and a small paddle of gas formed under the car, but at that time I wasn't sure if it was the A/C condense, or gas. Took car out of the garage and left it there overnight. Drove the car next day and the smell was less noticeable, and it disappeared in about two days. Next two weeks did not ill up the tank completely, and there was no smell or leak. Yesterday, Sunday, Aug 22nd, I filled the car with gas again until the pump stopped, and the smell came back instantly, as I was driving home. Parked the car in the driveway and immediately noticed a large paddle of gas forming under the left rear wheel. Removed back seat and both fuel tank pump metal covers, and both plastic fittings/covers were leaking gas, more so on the driver's side. There are hairline fractures in both covers, and both are leaking gas. Removed both covers and siphoned gas out of the car until the leak stopped. I went to Hendrick's MB of Durham and asked about the recall, they denied that my car qualifies. The parts alone were quoted at $1229.12, without labor, and I was told fuel tank worth about $1,000.00 (without labor) may need to be changed as well. the federal safety agency recall campaign 2013020002 mentions my car. My defect is worse than most because both sides leak gas, not just the pump, and both have visible with naked eye fractures that leak gas. I cannot understand how is my risk of fire and death while driving less than that of other MB's with exactly the same failure, in the same class, and the same C300, for the same year. I expect the cost of repair with labor to be more than $3,500 .

I began smelling gas in the cab of the vehicle. After refueling, the vehicle was leaking gas from the right side in the driveway of my residence and the odor of gas in the cab began to increase. Merecedes personnel refused to acknowledge other issues and wanted to begin at their starting points regarding repairs. When this recall was addressed, I was informed it did not apply to my vehicle. After a lengthy elimination process, we learned the fuel pump flange had failed in this model as it has in other similar models. Merecedes at this point refused to extend a warranty consideration so I sought out an independent mechanic to repair it. Now mercedes is refusing to reimburse the cost of the repairs.
