2013 Mercedes-Benz E350: fuel leak

Filed Jul 16, 2025 · Fuel system · CA

I am the owner of a 2013 Mercedes-Benz E350 and am writing to formally express my concern regarding a persistent fuel leak issue I have experienced with my vehicle. Over the past months, I have spent more than $4,000 attempting to address this problem. Repairs have included the replacement of the fuel canister and the fuel pump. Despite these efforts, the vehicle continues to leak fuel from the area near the rear right tire, both when the vehicle is in motion and when it is parked. This issue presents a significant safety risk, not only to myself but to others on the road. I am aware that there is an existing recall for the 2014 E350 model related to similar fuel leakage problems. Given the similarities in design and the nature of the defect, I strongly urge Mercedes-Benz to investigate this matter and consider extending the recall to include the 2013 E350 models as well. I believe this is a critical safety matter that warrants immediate attention to prevent any potential accidents or hazards. Thank you for your time and consideration. I look forward to your response and to a resolution that prioritizes customer safety.

I noticed the smell of gas in the garage whenever the car was parked in the garage. The mercedes dealer determined that the right side fuel sending unit was leaking gas. The vehicle has a metal gas tank and the fuel sending unit is built into the gas tank and therefore the entire gas tank had to be replaced at a cost of $4209.65.

Fuel leaking from right rear area - when car is filled up - I stopped when pump clicked off - did not overfill - you had a extension of warranty on mercedes up to 2009 but this 2013 has the same problem its under the rear seat passenger side - right where a car seat would be for a kid - someone is going to get killed by this. This should be a mandatory safety recall !! 2013 should be included in the extention big problem we bought this car used and 1st time we filled it up
