Other Fuel System Tank Assembly Problems of Mercedes Benz E500 - part 2

There was a fuel leak that caused the car to smell of gas when the tank is near full (3/4) to completely filled. The fuel has not been leaking to the ground and I have been unable to pinpoint exact location. When I would go into my closed garage after the car had been parked for a while the smell of fuel is too strong to ignore. My mechanic told me the source is the sending unit and tank assembly. He told me the failure was common and the situation could become very dangerous if ignored. The cost to replace the tank is going to run $2,000. The car has never been damaged and should not require a tank replacement at this point in its lifecycle.

Gas tank leaks at the top near the sending unit. Above 3/4 tank level, leakage takes the form of puddles on the floor under the car an noxious fumes are very strong.

Very strong fuel smell when parked inside the garage. Fuel leaks around the fuel tank. I was afraid to open up the garage door because of the smell/fumes. Very concerned that the car might explode.

Was just informed today that our 2005 mercedes e 500 sedan needs the fuel/gas tank replaced due to a leak in the upper portion of the gas tank. This is nearly a $2000 job and I believe mercedes needs to address this issue for owners effected by this problem the NHTSA action number on file for this issue pe12001 from browsing the web, I see this is an issue with other mercedes owners as well.

Tl- the contact owns a 2003 Mercedes Benz E500. The contact stated that while parked, there was a strong gasoline fuel odor around the vehicle. The vehicle was taken to an independent mechanic for diagnostic testing. The mechanic stated that fuel was leaking from a fracture at the top of the fuel tank. The manufacturer was made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 81,000. Kmj.

Car engine light went on. Dealer replaced charocal cannister. Two weeks later auto repair shop was correcting a shimmy and discovered a leaking fuel tank.

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

Noticed a fuel smell in cabin of vehicle. Brought vehicle to authorized mercedes service center who determined a seam in the plastic fuel tank had split allowing vapors into the cabin. Required complete fuel tank replacement.

Car was not moving when we noticed a strong odor of gasoline coming from the rear seat area, when we pulled into our garage the odor was so strong we moved the car to the outside to prevent a possible fire in our home, I called the dealer and the service manager immediately told me that he thought the gas tank sender/sensor was leaking and possibly that both sensors were leaking and possibly the tank. He also told me that gasoline could be pooling on top of the gas tank causing the odor. He later called me and confirmed that all of the above had happened and could be repaired for approximately $3250. 00 I ask if this was a recurring problem on this model he said that there were no recalls or warning but they had seen this problem before. I then went on line and found a lot of blogs describing my problem almost identically. In my opinion this is a serious defect in the construction of this car and could and probably will cause serious injury and possibly death to some one riding in this model. I believe there is enough evidence in the recurring blogs that mercedes is quite aware of this serious safety problem and are probably ignoring this very expensive fix, please do not ignore this complaint until someone or several are hurt or killed.

After refueling, fuel fumes were emitted into the vehicle and garage where parked. Extremely overwhelming smell and danger obvious. Taken to mechanic and fuel tank has leak at sensor and sending unit seals. The dealer has refused to repair as no recall issued. Owner found many others with exact same issue on this model series and year online and with mechanics experience. Strong potential for imminent fire hazard. Gasoline fumes are hazardous to vehicle passengers, with numerous medical issues noted in research. Strong enough in cabin to cause dizziness, illness or loss of consciousness.

I noticed strong gasoline smell in my 2006 E500. The smell is very strong inside the cabin and my vehicle always stays in the garage. When I walk into the garage I also smell a very strong gas odor. I had similar smell 2 years ago and got it to the dealer. They said the fuel tank opening under the rear seat was not properly closed and leaked the gas. They claimed they fixed it and also replaced any insulation that was there the to ensure smell completely goes away. For a while I was not getting the smell but it suddenly started coming and it is very strong. I also hear that it is affect lots of vehicles.

The fuel tank cannot be filled up completely. Doing so causes the car to smell like gasoline. There seems to be a fuel leak on the tank which causes the gasoline to spill. The odor comes mostly from the back seat of the car. If the tank is filled, the car will have the gasoline odor for weeks even with the windows left open. This is quite dangerous in many ways since I have an infant who is required by law to sit in the backseat rear faced.

We purchased this vehicle recently from a private seller. The first time we filled up the tank, we noticed a very strong gasoline odor. I called the seller and he told me that the only way to avoid that is by not topping off the tank. I figured this wasn't normal, so I started doing some research. Turns out mercedes e class vehicles have a problem with the fuel seal. In fact, there was a recall for this problem, but the local mercedes dealer does not want to honor it because they say it is only for the amg models. But my model has the same problem. Then, upon further investigation, I found that a class action lawsuit against mercedes was being filed this year for the same exact issue concerning e class vehicles from 2003-2009.

The contact owns a 2005 Mercedes Benz e 500. The contact stated that there were gasoline fumes inside the garage where vehicle was parked. The contact soon discovered that fuel was leaking from the vehicle and onto the floor. The vehicle was taken to the dealer who stated that the fuel tank had to be replaced. The fuel tank was not replaced. The manufacturer was made aware of the failure, however no further assistance was provided. The manufacturer advised to avoid refueling the fuel tank to capacity. The failure mileage was 147,000. The current mileage was 160,000.

Gas is leaking under the back seat and garage is filled with gas smell. When dealer opened the seat, pool of gas was found. Dealer replaced sender units and the issue never resolved. Now the dealer is saying tank is leaking and mercedes refuse to pay or assist for the repair. It is defect fuel assembly and very high safety issue. We sitting on top of the leaking gasoline and company refuses to acknowledge the problem.

After refueling, car had strong odor of fuel leaking. Fills garage with fumes. Worried that pilot light will ignite fumes. Also, fuel gage sticks on 1/2 tank even when tank is empty.

After refueling a strong smell of fuel vapors is present inside the car for varying periods of time dependent upon temperature and whether the car is in the garage or outside. Based on various message boards most indicate a faulty fuel tank or connections to the fuel tank.

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.

Everytime I fill my fuel tank I've noticed a strong fuel odor. Upon inspection I have found the fuel tank to have traces of fuel on the exterior of tank, so my tank has a leak somewhere.

I bought the car in may of 2011. Upon purchase I noticed a smell of fuel after I would top the tank off. I had a dealer repair it (~$800) and then noticed it again this past winter (Dec 2012). It is the same problem as before, leaking (fumes only) just on top of the tank under the back seat. It is the exact same issue as described in articles I have read about the NHTSA investigation of mercedes-benz e-classes. This is a problem, I believe it should be recalled.

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 fumes leaking above gas tank gasket, and going into car from under rear view seats, this is a emissions matter and safety matter, its not healthy for people to breath gas fumes every time they pump gas. Also to the matter, I am a certified smog technician and this is a fail smog inspection due to leaking gas fumes. My car is a ulev vehicle so the warranty is up to 150000 miles, but I'm writing this because it should be fix. Lots of owners are just ignoring it due to cost or repair!! this have been an ongoing problem with this vehicle.

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

The fuel tank, pump and sender started leaking. Fuel had pooled on top of sender unit. This made my daughter in the back seat so ill we had to take her to urgent care. I called a dealer. Bought "improved seals for the sender and pump. The problem is not gone. Now the dealer is telling me it could be $1500-$2500 to replace the tank and sender/pump. It is unreal that a potentially lethal fuel leak is widely known about all the 2003-2008 e class mercedes and nothing is being done. Does somebody have to burn to death in a fiery crash before mercedes or the NHTSA gets serious about this issue. The car has had to be parked. I am still making payments on it and have to go buy another car that is not a rolling fuel explosion waiting to happen. I am begging the NHTSA for the safety of hundreds of thousand e class owners to have mercedes recall these cars.

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.

We had noticed a strong smell of gasoline in our garage each morning just after we had filled the car with gas. We took the mb to myerstar mercedes, they found crack in the upper middle front of the plastic fuel tank and had to replace the fuel tank. This defect should never have occurred in a vehicle that's only five years old with 45,000 miles. This defect could have caused an explosion and fire in our garage. Copy of movie.

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.

The contact owns a 2004 Mercedes Benz E500. The contact stated that there was a strong odor of fuel emitted inside of the vehicle after refueling. Whenever three gallons or more of fuel was dispensed into the fuel tank, the fuel would spew from the filler neck onto the ground. The vehicle was taken to an authorized dealer and they were unable to provide a remedy. The manufacturer was not made aware of the problem. The approximate failure mileage was 42,000.
