2007 Mercedes-Benz E350: check engine light

Filed Oct 29, 2026 · Fuel system · MD

I first noticed the problem around March 2026. When I fill the fuel tank of this 2007 Mercedes-Benz E350, gasoline pools on top of the tank beneath the rear seat, inside the passenger cabin. I have breathed gasoline fumes from it. There was no fire or crash. An independent Mercedes specialist's records include a March 2026 recommendation noting a very fine EVAP leak at the fuel tank and/or vapor line and that the tank is no longer available. On May 29, 2026 (65,138 miles), with the check-engine light on and a strong fuel smell inside the vehicle, the shop replaced a leaking left fuel pump and seal. A fuel-system test that day indicated further checks were required. The gas pooling continued after the pump was replaced. On July 28, 2026 (66,067 miles), the shop noted that the fuel tank is warped. I wrote to Mercedes-Benz USA on October 13 and October 16, 2026 with my service records and have not received a response.

Vehicle began shaking on the highway. It was coming from under the front hood and was shaking the steering wheel. The check engine light came on. I pulled over and had it towed to the Mercedes repair shop. They said it was related to a bad balance shaft and that it was a systemic problem with the engine in certain Mercedes e350s. I was told I needed to replace the camshaft and it would cost $6,000!!! After some research, it looks like Mercedes agreed, back in 2015, to cover only certain of these Mercedes, but there was no recall. I could have been killed if I was rear ended.

Problem: car leaks fuel to the ground near the rear exhaust part of the car when gas tank filled past 3/4 full of a tank. Car leaks fuel, and smells excessively like gasoline inside, and outside of the car. This could be a potential health risk due to the fumes of the gasoline, and gasoline leaking. The problem could be a safety issue due to gasoline potentially leaking on the exhaust, and igniting. The car also will not pass emissions due to evaporation leak check engine codes. This happens every time a gas fill up more than 3/4 of a tank of fuel. I have pictures of the fuel leak.

In 2011, I purchased my vehicle from a dealership as certified/preowned at 46,717 miles. Regular maintenance was kept up at the dealership. In 2015 at 74,563 miles, I brought my vehicle in for 2 problems: a check engine light had come "on" and my vehicle was experiencing vibrations from the power train when turning and shuddering when making sharp turns at low speeds. The check engine light was a result of a balance shaft engine problem which was, at the time, in a class action suit regarding this problem for these vehicles. The manufacturer agreed to pay a portion of my repair for the balance shaft issue. The second problem turned out to be a transfer case issue. The dealership stated I had a bad transfer case and they recommended I have the transfer case replaced. At the time, I could only budget myself for the balance shaft repair and 4 new tires. The transfer case oil was changed which slightly improved the vibration/shuddering issue. I currently still have this issue more severely and require the transfer case be replaced. My vehicle's transfer case oil was changed at 30k miles by the previous owner. Through research, I have discovered that in january 2009, a manufacturer bulletin came out that specified my vehicles VIN number was included in the stated problems with the transfer case. They had installed defective transfer cases at production in 2007 and should remedy this! I have spoken to the manufacturer and they will only pay 25% of my parts for this repair which leaves me with a $3200 bill for a problem they knew about. On many occasions, while waiting for my vehicle to have maintenance completed, I over heard service representatives speaking to other customers by phone or in person. The service reps indicated in many instances that the problem the customer was having with their vehicle was due to the transfer case. These transfer cases should be recalled!
