Fuel smell on fillup. This vehicle has previously had the factory recall performed.

I am getting a strong gas smell from the car when standing outside of the car with it running and long after the car has been shut off. If I park the car in the garage after a drive and then come back to it 30 minutes later my whole garage smells like gas but cannot see any leaking.

Smell of gas in the car checked and found a pool of gas on top of fuel sender below the rear seat behind driver side.

There is a huge fuel leak coming from underneath my vehicle. It is located under the drivers side rear passenger seat. I lifted up the seat and it is covered in fuel emissions.

The contact owns a 2005 Mercedes Benz E55. The contact stated that the vehicle was serviced multiple times by the dealer for a manufacturer's voluntary recall for a defective fuel sender unit. The vehicle was still leaking fuel and the smell of fuel continued to emit from inside of the vehicle after the repairs. The vehicle was taken to back to the dealer. The manufacturer was not contacted. The vehicle was not further repaired. The failure mileage was 95,000 and the current mileage was 1114,000.

Every time I fill my vehicle up with fuel, there is an overpowering odor of gasoline both outside of the car, and inside the cabin. The smell is strong enough to cause a headache in short order. When removing the back seat of the vehicle, you can observe standing fuel on the fuel sender assembly. I'm unsure if this propagates from the spot of the build up, or is from another place and this is where it ultimately ends up. A large concern for me, besides the exposure to gasoline fumes, is the proximity to the fuel build up to electrical wiring, which I believe would constitute a fire hazard. I previously had a voluntary recall done on my car in 2008 that had to do with the fuel system, but I'm not convinced that actually fixed the root cause of this issue.

Fuel sending unit is leaking, there is a heavy fuel smell inside the car.

2005 mercedes E55. Vehicle has a strong gas smell. Found gaskets at fuel senders leaking again. There was a recall to repair this issue in 2008 seems like it didn't fix the issue.

After refueling vehicle, I noticed a strong odor of raw gasoline in the interior of the vehicle emanating from the rear seat area. In July, 2011, a mercedes dealership determined two sending units located under the rear seat were leaking, necessitating their replacement. The car was out of warranty and there was no mention of any recall or service campaign relative to the defective parts. The approximate cost to me was $2000. 00. Just last week, on April 6, 2012 the same event occurred wherein I refueled the vehicle and, again, noticed the same gas odor. This time I also noticed fuel had spilled on the pavement in the vicinity of the right rear portion of the underside of the vehicle. The vehicle was returned to the dealer that made the original repairs and I am awaiting their assessment of the problem. This recurrence happened just nine months and 6,000 miles after the previous repair. In the interim, I became aware of a 2008 recall involving a fuel leak on my model vehicle. I have asked the dealer to determine if the July, 2011 repair should have, in fact, been covered by the recall campaign. I have also since learned that numerous owners of my type vehicle have experienced similar gas leaks leading me to believe this is a widespread, frequent problem which has serious ramifications regarding personal safety and environmental protection. My complaint is that the manufacturer appears to have improperly designed a part or series of parts that either alone or in combination fail resulting in a hazardous fuel leak. Given the recurrence of the leak in my case in such a short period of time, it appears the remedial action is ineffective in solving the gas leak problem.

On June 9, 2011, there was a detectable fuel smell on the interior and immediately surrounding the exterior of the vehicle. On June 10, 2011, the vehicle was taken to mercedes-benz of laguna niguel, CA. The mercedes technician diagnosed the issue as a bad fuel sender unit. Mercedes failed to mention at the time that there was a recall for this issue which they described as "mechanical stress on the fuel filter module" (voluntary emissions recall campaign #2008-020001). Parts and labor to replace the fuel sender units cost $1,620. 20. This repair seemed to have corrected the issue temporarily. On October 17, 2013 I took the vehicle into mercedes-benz of foothill ranch, CA for routine service. The technician again identified the smell of gas in the vehicle and diagnosed the problem as a crack in the fuel sender unit. The mercedes service associated quoted approximately $1,600 to again repair this issue. This issue is clearly a problem with the vehicle design and mercedes continues to charge its customers to repair this flaw. I'm concerned for my health and the health of my wife and two children, ages 1 and 4. Inhaling gasoline, especially the benzene component is known to increase the risk of developing cancer in humans. I'm also concerned that the vehicle may be susceptible to exploding if this issue is not resolved. Your help would be appreciated.

Fuel leak at fuel transmitter passenger side under rear seat.

I own a 2005 amg E55 Mercedes Benz. The fuel sending unit is leaking gas into the car under the rear seats. This was a recall issue in 2008. Car was taken to mercedes and they said they fixed it. Now I am getting the same gas leak and fumes into the car. When I called mercedesa and asked what they fixed they said they dont know if they fixed the left or the right side. No one wants to take responsibility for this issue. This car was purchased from the us specificallt atlanta georgia.

During April/March of 2011, I noticed after filling up the car fully of 18 gallons at the gas station, the next two days the car would smell like gas when parked in my 2 car garage. Once I stepped into the garage, there was an overwhelming smell of gas. Googled this on the web and found mbworld. Org where common cases for the e class model. Pulled the rear back seats and saw that gas was pooling around the rim of the fuel sending unit. Somehow fuel had seeped up past the gasket/unit. Having a less than 2yr old sitting right above the rear back seat, I felt this needed to be taken care of ASAP. Took to american service center, arlington, va mercedes dealer. I found a TSB regarding the fuel sending unit that would be replaced free of charge. VIN was pulled and showed this already was done on my vehicle. Basically I had to pay out of pocket $956 to get a new fuel sending unit put in. So far no fuel smells, but am aware that this is just a quick fix. My 2006 e500 4matic that I also own is starting to have this smell now when filled up. Will be taking it to the dealer as well, but I have cpo warranty from the dealer which will cover the repairs.

Fuel sender unit leaked into the top of the pump area causing a smell of gasoline in the car. Sender unit was repaired but smell remained. Sender and pump unit were replaced and after 14 months the smell of gasoline is back along with pooling on the top of the pump area. When filling the car at the gas station there is sometimes a small puddle of gas under the rear filler area when done.

2005 Mercedes Benz E55 fuel sending unit was spraying gas into compartment which is underneath the driver side back passenger seat. There was a recall on the car already and it was replaced and failed in just 18months. Brought the car to mercedes of freehold and they said "been changed under recall" and they cant do anything for me now that the new part has failed. Ended up buying the part out of pocket and replacing it because it was not under warranty any more. Gas being sprayed under the back passenger seat is not safe at all! not to mention my cabin was filled with gas fumes.
