Other Fuel System Tank Assembly problems of the 2003 Mercedes Benz E500

While the vehicle was on the highway the car lost power. Pulled over for visual inspection, noticed the fuel was leaking rapidly. Immediately shut off the car. Had vehicle towed to local Mercedes Benz dealership. Dealer verified the tank was leaking.

Strong fuel odor coming from vehicle when tank full. Doesn't happen if tank is 3/4 full or less. Any recalls? will dealership fix problem?.

Strong fuel smell from driver side rear seat. The smell spread to the cabin and the whole garage. This happens when the fuel tank is full. The smell will lessen after the tank is about half full.

I have had this problem for a while now. When I fill up my fuel tank there is a drastic smell of gas. I believe this is a safety issue. I had to leave my car out on the street in fear my water heater when igniting would set off a explosion. I am sure mb knows of this situation since I have seen numerous remarks and instances on just this subject. I would hope that mb will address this problem. I took it to the dealer and indeed they said that the fuel sending unit has a crack on top allowing the fuel to leak when filled up to the full mark. Thank you advance in reporting this to mercedes.

When the tank is full it has a very strong smell of gas inside and around the car for a couple of days, also misfire during these few days. I'm afraid this might cause a serious fire. I would like to hear from mercedes-benz ASAP regarding this possible dangerous issue, any help to correct this matter will be appreciated.

The car when we have full tank gives a very strong smell of gas, until couple of days, also when ging slowly there is a misfire on the engine. Reading on the forum says this is a know incident with mercedez. I am afraid this might cause fire. I would like to talk to dealership on this, any help is appreciated. Rajesh dikonda.

We purchased our used vehicle in may, 2013 and have found the gas smell problem to grow increasingly worse. Especially initially when the tank is completely filled, it is very strong both outside and inside.

Vehicle is parked, strong gasoline smell inside and outside of vehicle. Especially if the gas tank is at least 3/4 quarter filled.

Extremely strong gas fumes when the tank is filled with fuel.

Reference to NHTSA action number: pe12001. The seal on my fuel sending unit began leaking. There has been no accidents with this vehicle, and this is a non-stressed item. The seal that isolates fuel in the tank from the passenger compartment has failed. Gasoline leaks around the sending unit seal around the electrical connections connected to the sending unit. This leak allows fuel to leak from the fuel tank into the passenger compartment due to failure of the seal with no input or outside action. After fueling, a fuel smell and fumes can be smelt in the cabin. When the access panel is opened below the rear seat, pooling fuel can be seen. This fuel has direct access to the passenger compartment.

Reference NHTSA action number: pe12001. Fuel sending unit leaking fuel resulting in fuel pool on top of fuel tank and under rear seat drivers side. Strong fuel smell inside vehicle with built up of fuel vapors causing eye nose and throat irritation-especially strong smell and vapor built up when fuel tank is full or near full. Full splashing on top of tank and nearby area dripping to floor-fire and explosive hazard, condition has worsened over time.

Constant fuel smell from inside and outside the vehicle. Worse after fillup. Goes away after 1/2 tank and a few days of driving. Fills the garage with fuel odor.

Gas smell when the tank is full. Gas leak from fuel tank.

I had refueled my vehicle and noticed the presence of gas fumes when I parked in my garage. I always use the auto shutoff at the pump so there was no concern for me to "top off" something I never do. I notice that if I filled my tank closer to the 3/4 or below level it was not noticeable.

The car had a strong smell of gasoline in the cabin of the car. I have since learned that the cause for that was a defective gas tank. After doing some research online, it appears that this is a known problem but yet the dealer has no interest in repairing the issue unless I was willing to pay for the repair. Seems an issue as serious as a defective gas tank would be covered.
