With a full tank of gas, gas leaked out of the top of the fuel tank where the fuel sender/filter is located. The fuel wicked up the foam wrapped around the signal/ power wires, came between the access panel screwed to the floor and the floor. This is the floor directly under the rear passenger seat. The fuel soaked into the insulation below the rear passenger seat and the foam seat. This continues to occur at all times until the fuel level reaches approximately 3/4 of a tank.

Check engine light illuminated, code scan revealed code p0456. Inspection reveals fuel leakage at both the left fuel sender and the right fuel pump housings. Liquid fuel is externally evident along with the associated smell of raw fuel vapor. This is a very common problem with these vehicles and the manufacturer should be held responsible for repair of what is a potentially dangerous issue.

I smelled a gas order that was progressively getting worse. I decided to pull the passenger seat to follow the smell and noticed a puddle of gas on top of my fuel pump sending unit. I decided to pull out the unit and noticed the unit was discolored around the connector terminals. I believe the terminal melted the sending unit causing the sending unit to leak fuel. I have this is a very common problem with these cars, please help.

I filled my tank with gas drove it home and parked it in my garage. Later I went out to the garage and smelled a very strong odor of gas. I thought my husband might have left a container of gas in the garage. A couple of days later I went to a friends home in the country side and noticed an intense smell of fuel in my car. I thought somehow maybe my husband transported gas in a container it the interior of the car, but he had not. I had to call road side assistance because on the return trip not only was the gas smell more intense, but I had a flat tire. Immediately road side assistance came changed the tire and took us home and drove the car to the mb dealership. I paid for a new tank to be installed and they paid to remove the padding and liner and replace it from the seat behind the tank. From 2010 to 2014 three more events of fuel smell in and out of the car after filling the tank have since occurred and required repair. Once it was said to be the lines or injection system. After the lines were repaired though the smell remained and this was solved by placing a new tank again in october 2012. The latest leak occurred just as the first, and on november 7, 2014 a new tank has not been placed yet. The interior of the car is intolerably caustic with gas fumes. I am out of warranty and am driving an explosive time bomb filled with carcinogenic petroleum. These cars need a recall. I see I am not the only to submit a complaint for this dangerous hazard. The tank fuel leak for the s class and e class spanning 2003-2008 is discussed on mercedes benz forums, as well.

Over the last few months I have noticed a significant smell of fuel whenever I get in and out of my e55. I had the dealer look it at during my last service a month ago and they said nothing was wrong... I have not noticed any fuel leaking from below the car. After viewing the hundreds of threads and comments on the following 30 pages on a mercedes forum, I decided to have a look for myself: http://mbworld.org/forums/w211-amg/363759-urgent-notice-03-06-e55-s-were-involved-fuel-sender-recall-bombs.html when I took off the metal covers on top of the passenger side and driver side sending units I found fresh fuel on top of both units. The passenger was very little. The driver side was significant and squirting out from a plastic nipple that is part of the sending unit. Mercedes refuses to take care of this problem based on the 30+ pages found on the link above. Your organization is aware of this issue, there is even a class action lawsuit against mbna. I will have my vehicle repaired at my own expense by my own mechanic because I don't have the patience to put up with an arrogant service advisor who will surely deny this is was ever a problem on the w211 e55 mercedes. I think its time that your organization force mbusa/mbna to recall these vehicles.

Very strong smell of gasoline inside and outside the vehicle. Regarding the interior, it was determined that there was a leaking seal at the fuel sender unit. The seal at the fuel sender unit was replaced in march 2010. This problem recurred in late 2013. In march 2014 the fuel pump assembly, fuel pump lock ring and fuel sender seal were all replaced with new parts. The problem has re-appeared again. Regarding the exterior smell it was determined that there is a fuel leak at the fuel tank vent area. This was initially manageable by keeping the fuel level below 3/4 full. In the last couple months this problem exists at any fuel level. This overwhelming fuel smell will completely envelop the entire garage within 15 -20 minutes and possesses an extreme health risk and potential for an accident to happen. The level of exterior odor now is so high that it penetrates into the interior of the vehicle, whether the vehicle is standing still, in motion and with the engine on or off. From the research I have done this exact same problem is common to this model mercedes benz and has been documented for a number of years. I have not received any notification or communication from mercedes benz at any time regarding this issue. This is unacceptable!

At approximately 9:00 pm on may 14th, 2014 I noticed strong fuel odor surrounding my entire vehicle upon exiting the cabin. I had just refueled and was stopping at a grocery store on the way home. I did a quick visual and sniff check around the vehicle and noticed that the smell was strongest in the vicinity of the passenger rear wheel arch. About 20 minutes later I returned to my vehicle and the odor was noticeably stronger. In addition to that, there was now an approximately 2 foot by 3 foot pool of gasoline on the ground on the passenger rear side. Furthermore, gasoline fumes could now be smelled inside the vehicle as well. I had my wife move the car out of the parking spot and could clearly see a trail of gasoline dripping from underneath the vehicle. I was previously aware of this as a potential issue with these vehicles but had not experienced this on my own vehicle until now. I knew better than to top off past the automatic pump shutoff - and I in fact did not top off - and this is not a case of fuel spraying out of the filler neck. There is a reason that would cause such a large amount of fuel to be leaking from these vehicle's fuel systems. I've had countless cars in my life and this is the first time something like this has ever happened to me. I have the original window sticker for my vehicle showing an original cost of close to $90,000. To have a condition where fuel is leaking like this is simply unacceptable - not to mention potentially deadly. I believe that mercedes benz states there is not any danger of ignition, but what if the ignition source comes from some other source unrelated to the vehicle such as a discarded cigarette or some other type of spark? Are we going to have to wait until people die in order to get mercedes benz to admit that there is a product flaw?
