What owners say
The contact owns a 2003 Mercedes-Benz E320. The contact stated that after refueling the vehicle there was an abnormal gasoline odor inside the vehicle. The contact removed the rear seat where the fuel tank was located and discovered that fuel was leaking into the vehicle underneath the rear seat instead of going into the fuel tank. There was no warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 73,000.
After fueling up, a smell of gas occurs. Slight gas puddle forms under the car after every fuel up. Drops gas gauge down and after that no more smell of fuel but still slight puddle of gas after leaving the car parked. Noticed it about a month ago and it seems to get worse. Doesn't seem safe knowing the car is leaking fuel.
Driver is experiencing a heavy odor of gasoline after fill up. Vehicle is not overfilled/topped off. Vehicle was sitting inside garage when owner noticed a heavy fuel odor and notified fire department to investigate. Per recommendations of fire department, keep vehicle out of garage until issue could be inspected by a qualified mechanic. Mechanic inspected fuel system and found fuel leak under rear seats near fuel pump/sending unit. Mercedes benz refuses repair issue saying it is not a safety issue. Gasoline fumes/vapors are especially heavy inside a single car garage, and if a ignition source is introduced it could become fatal.
Filled up gas tank and had fuel odor inside car and fuel leaking outside the car until fuel level was around 3/4 of a tank. I believe that mine falls under all the other problems listed for fuel leaks for other w211 mercedes. The extended warranty for this was only allowed for original owners and not for anyone that purchased used.
Oil cooler seal leaking gasket causing fire hazard
Heavy fuel odor emanating from vehicle. Vehicle and possibly structures could catch fire if fuel is leaking and an ignition source is introduced. Only viable reason why fuel odor is present is either the fuel tank is leaking at a location or the vent has failed. Vehicle fuel odor is especially strong if vehicle was filled up recently but is present 24/7.
After filled up the car with gas. Strong gas odor and gas leaking from drivers side rear of car. While driving and while parked in the garage extremely unsafe!!!
Fuel leaking to the inside of passenger compartment under access port under rear seat cushion, that's the location of the fuel pump. I made an appointment with tucson mercedes benz to inspect the car since I believed that a mercedes recall would correct the problem. I had several discussions with service advisor mark schofield and he assured me twice that the recall is in place and they would fix the fuel system defects without charge. He called me this evening and told me all about why tucson mercedes would not cover the repair, I was told the extended warranty program ended 2/21/2018. I bought the car on 4/5/18, filled it up with gas on 4/08/18 and the car was filled with fumes that night as well as in my garage. Tucson mercedes first said that the tank was leaking at the vent tube between the left and right access points. He told me that the cost would normally be $3000 but he reduced it to $2000. I asked mark how the fuel could run across the top of the tank, climb the locking ring and puddle on top of the left side fuel pump? He also told me that mercedes could not just replace a portion of the fuel system without replacing the entire fuel system, including the tank. Also, not true. He said that upon a second examination was made and there appears to be a crack on top of the fuel pump and now that's where the leak is coming from. Now his price to repair all is $770 + tax. After a few words more, the price dropped to $700 + tax. I feel that mercedes should just fix my vehicle and call it good. This learned that this car had a fuel pump installed at 59,000 miles. I missed their self imposed cut off date by about 6 weeks, not so much time for such a serious manufacturing defect to health and safety. The fumes inside my car and garage could have caused a fire or worse yet, an explosion. The problem first appeared after the first time I filled the tank.
