Other Fuel System Tank Filling/charging problems of the 2005 Mercedes Benz E55

After filling vehicle gas tank, extremely strong fuel odor noticed in cabin and outside of vehicle. Smell existed both at standstill and at street speeds (40mph) with windows down or up.

Strong fuel smell after filling tank, drivers side fuel sending unit on drivers side of fuel tank leaking fuel. Noticeable cracks in corners of unit around fuel pressure sender.

After filling up the gas tank to full, I drove my vehicle home and noticed a distinct gasoline smell in the garage a few hours later. The next morning, the smell in the garage was even stronger and upon opening the doors of the vehicle, it was clear that the gas smell was coming from the vehicle and was strongest inside. In November 2012, crown automobile, a mercedes-benz dealership, performed service on the car and "found the right side fuel level sensor seal leaking". The seal was replaced and the fuel tank was refilled and checked for leaks. At that time, no leaks were found. However, the smell has reappeared and is consistent with other complaints about this vehicle.

Very strong fuel smell after filling up tank at gas station. Fuel pumps and senders located under rear passenger seat. There are 2 of these pumps one on each side of the vehicle. After removing the rear seat bottom access is gained to the fuel pumps/senders. Appears to be fuel puddling around the pumps/senders.

Strong fuel smell began occurring inside & outside of vehicle after filling the car up with gas. Fuel leak discovered at gas tank fuel level sending unit. This is a widely known defect on the mercedes w211 platform from 2003-2009 year models. Mercedes dealers contacted will only make the necessary repairs at my expense which could exceed $2000. This defect is hazardous to anyone driving with this fuel leaking condition and is also very environmentally unfriendly as raw fuel being released.

Strong smell of gasoline in and around car after filling up. Smell remains until fuel level is consumed below 3/4 of a tank. Fuel spills from the car when accelerating. When car is filled with fuel the pump is turned on until it shuts off, never topped off. Car was originally purchased in California when new and is operated in colorado between 5000 and 10000 feet in elevation. Can no longer park the car in the garage due to overwhelming fumes. I am concerned this is a health hazard as well as a fire danger awaiting a source of ignition not to mention any added magnitude it may contribute in the event of an accident.

Filled my gas tank with fuel and subsequently after filling up and getting back inside the vehicle I could smell a strong odor of fuel inside the vehicle. I took the vehicle to a friends house down the street got on the internet to research the problem and found out theres an existing problem with the top of the fuel tank that has explained theres a seal problem. I took the rear seat out of the vehicle to access the area along with some other nuts and bolts and found a pool of fuel sitting on the top of the fuel tank. After putting everything back together I noticed underneath the vehicle it had leaked onto the pavement. I am very concerned the vehicle is not safe and mercedes is aware of the problem and hasnt done anything to address the situation. Your assistance in this matter is greatly appreciated. Thank you.

After filling tank & parking in garage, noticed strong fuel smell the next morning. Subsided once fuel level was around 3/4 of the tank. Next time filled up, same thing occurred. Called mercedes & stated possible problems with fuel sending unit seals. Took to dealership on may 24th and stated fuel sending units must be replaced along with fuel shut off switch and the fuel tank as well due to hairline cracks at neck causing the leak. Total cost is $3100. I have searched online & noticed this seems to be an issue plaguing these cars. I understand issues will happen, but given the nature of these & the broadness of vehicles affected that there should be a recall for this issued. I would like mbusa to reimburse me for these expenses.

After filling up the fuel tank. . . Strong fuel odor inside the vehicle.

I smell fuel inside and outside the car after filling the tank. I smell this more in cooler months than warmer months. I've been smelling fuel for over 2 years now but didn't think much of it. I have recently had an engine light come on and did some research. The fault points to the fuel system. I'm wagering that when I remove the back seat, I'm going to find evidence of a fuel leak like many others online have found. The car has not been in any recorded accidents that I'm aware of. It's used premium fuel since I've owned the car at 50,000 miles. I now have over 163,000. I also take additional interest in the fuel issue now that I have a child in the back seat that has also commented about the smell.

There is a strong odor of gasoline in the vehicle after filling the fuel tank. I have verified that gasoline puddles on top of fuel module underneath access cover on driver's side under rear seat. The car also causes a strong odor of gasoline outside vehicle when parked in an enclosed garage. I am concerned about the car catching fire or it causes a fire in my house when parked in the garage. The dealer acknowledges this defect, but indicated there is currently no recall to fix it.

After filling up the gasoline tank, the car will begin to emit a very strong fuel odor on the drivers side rear wheel well which will last approximately 2-3 days until the gasoline tank begins to empty out, then the fuel smell will go away until the I fill the tank again.

Initially, after topping off the fuel tank and parking the car in my garage, I noticed a strong gasoline odor. A close inspection of the engine bay, gas cap, and under the car did not reveal any noticeable leaks so I suspected that some gasoline must have dripped down the overflow tube when filling. After driving the vehicle for a day the odor began to dissipate. The problem re-occurred after filling the tank again where I was careful to ensure that no fuel leaked outside of the filler tube. Occasionally, I now receive an intermittent emissions light on my dash. The warning light does not stay on long enough to record a code when checked at the service department. The odor appears to be coming from the interior of the car. I now now fill it to no more than 3/4 of a tank and drive it very little until I can have someone successfully locate the source of this leak.

After filling the gas tank over 3/4 full there is a strong fuel odor outside the car from the driver rear wheel well area. The odor is strong enough that the car cannot be parked in a closed garage. The odor persists until the fuel level is back below 3/4 full. The issue repeats consistently every time it is filled over 3/4 full so I am unable to ever fill the tank completely. The service campaign #2008020001 for the fuel filter module was performed at park place mercedes in August 2008. Shortly afterward I started getting some bad fuel odor inside and outside the car so the work was redone be the dealer in September 2008. The issue reappeared in 2012 about 30k miles later.

After filling up the gas tank in my 2005 Mercedes Benz E55 up with gasoline, there are overwhelming gasoline fumes that engulf the interior and is also prevalent from the outside of the car. When entering my closed garage after a gas fill up, the entire garage is engulfed by the very strong and distinct odor of gasoline. To further the description, please refer to the current investigation with the NHTSA action number: pe12001 as reference to what is happening with my vehicle. Thank you for your assistance.

My car has been to the dealer no fewer than 4 times for various fuel system related issues. The symptoms of each part failure involve a pervasive gas smell filling the cabin of the vehicle, and gasoline usually pools under the rear seat. The smell is so potent that the car is undriveable, and the pooling of gasoline inside the passenger cabin must be extremely dangerous. The gas tank, fuel senders, fuel pump, charcoal filters, and gasket between the tank and fuel senders have been replaced to no avail. I have had to fight to have this paid for under my existing Mercedes Benz extended warranty. My warranty expires in July of 2013, and I am extremely concerned that this will continue to happen. My most recent dealer visit for this problem was 2 days ago. Nothing was replaced, and they confirmed that oem parts replacements have been used to fix the issue each time. . . Which is a problem because they continue to fail.

This complaint is in reference to NHTSA action #pe12001. During 2009, at approximately 31k miles on the vehicle (2005 Mercedes Benz E55), a strong fuel smell/odor was evident in the passenger cabin. The smell was strongest at the rear seat driver's side. This issue was brought to the attention of a service advisor at a Mercedes Benz authorized service center. An open recall was indicated to replace the driver and passenger side fuel sender units in the fuel tank, located below the rear seat. The recall was performed at 31,300 miles and while the fuel tank was not replaced, the problem did appear to be resolved. During 2012, at approximately 50k miles, the same strong fuel smell/odor in the passenger cabin reoccurred, subsequent to the factory warranty expiration date. Upon closer inspection, after removing the rear seat bottom and driver and passenger side access panels, it was immediately apparent fuel had collected/pooled in a cavity on top of the fuel tank where the driver side fuel sender unit is located--ultimately confirming some type of fuel leak. When inspecting the passenger side fuel sender unit, the area appeared to be dry with no fuel leaking on that side. After this inspection was completed, the pooled fuel on the driver's side fuel tank was removed and the surrounding area was cleaned and dried before reinstalling the access panels and rear seat bottom. Currently at 54k miles, the fuel leak has been somewhat lessened/avoided by only filling the fuel tank to no more than 3/4 capacity (or, about 15 gallons out of 21). There remains, however, a slight fuel smell/odor reoccurring during instances when the vehicle has been parked outside for extended periods in the summer heat. Also, when the fuel tank is filled to capacity, the strong fuel smell/odor immediately returns and again requires the unsettling task of cleaning up the leaked fuel.

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.
