2007 Mercedes Benz E350. Consumer writes seeking reimbursement for fuel tank component repairs.

- Maiden, NC, USA

My car has a strong gasoline odor. The dealership said the fuel tank is leaking and needs to be replaced. They have denied warranty coverage on a leaking fuel tank. Please reference NHTSA # EA13003. This problem has been acknowledged and a warranty program put in place by Mercedes Benz to avoid a recall. Now, they are denying warranty coverage. Can your investigative team open this case up and help us- consumers. On the surface, this appears to be an ethical problem for Mercedes Benz. Repair cost $976 for a new fuel tank. Please help.

I began smelling gasoline when inside the car. I called the dealer to schedule an appointment to have the car checked for fuel leaks. The dealer suggested bringing the car in the following week. So I took the car to a nearby oil change service company and had them change the oil and check for a fuel leak. The oil change service could not find a fuel leak, but confirmed that they smelled gasoline and suggested I take it to the dealer. On December 10, 2014, I took the car to the dealer and was told that they found a fuel leak at the fuel filter assembly that is under the back seat and that the repair would be $649. And it was possible that once they repaired that, the leaking at the tank may increase requiring replacement of the gas tank. As I waited for the repair, I searched the internet to see if this repair was the subject of a recall. I found that this exact issue is being investigated by the NHTSA, NHTSA action number: PE12001. I showed the service technician what I found on the internet and he said all they could do is replace the fuel filter assembly to see if that would fix the leak. They changed the tank inner module, 211-470-60-94, for $264; 2 seal rings, 211-471-05-79, at $39.53 ea for $79.06; discounted the labor from $343.66 to $187.50; and miscellaneous charges and sales tax, for a total service repair bill of $576.03 for replacement of fuel filter system and seal rings. At this time it is unclear whether this will in fact fix the problem or make it worse.

Gas smell at all times. Greater smell when stored. Engine light came on. Took to the dealer, charged $4,000 to repair.

I began noticing a strong smell of gas from inside and outside the car. I took the car to the dealer and they removed the rear seats and access panel to the fuel sending units. They found fuel leaking from the fuel sending unit with fuel level sensor on the driver's side. It was leaking from the unit itself not the seal ring. Damage code 047006767. Dealer indicated it was necessary to replace. Replaced fuel sending unit with fuel level sensor and replaced with new, reconnected lines and connectors. Reinstalled all components, added fuel back in the tank and check for leaks from sending unit. They determined the unit was not leaking once repaired. Flash forward to 7/24/14 and I have issues again with the fuel system. Components of the system were replaced again at a cost of $1,752.16. I am very concerned about the safety of this vehicle. Please continue to investigate this issue with this model and year.

Strong gasoline smell after I fill the tank up. I never top it off, normal fill up until the gas nozzle clicks. The smell comes from left rear side. I am concerned that it will catch on fire one day.

2007 Mercedes Benz E350 noticed strong fuel/gas odor inside car after filling up gas tank and would subside after gas tank was approximately 3/4. my children & I had to roll down the windows while driving due to feeling nausea. This has occurred often for weeks. Last Thursday on 8/7/14 I was driving vehicle coming to a signal light at an intersection and the car started shaking like is was loosing power, then it shut off in the middle of the street at the intersection. I tried starting it back up and it would not start at all after cranking for few seconds looking like it was not getting fuel at all. I had to get my car towed, the mechanic said it was the fuel pump and it will cost $2000 to replace. This seemed extremely hazardous for car safety having to smell the fumes and almost causing an accident. There have been an enormous amount of complaints regarding the fuel emission pump/tank & this manufacture defect of the car which is a major road safety hazard item should be considered as a safety recall from Mercedes car company.

Gasoline is leaking from fuel tank.

2007 Mercedes Benz E350 showed symptoms of cranking but not starting intermittently and also noticed fuel odor in the compartment often for weeks. Eventually fuel odor was noted within the interior of the vehicle and the car will not start at all after cranking for few seconds looking like it was not getting fuel at all. When the car was arranged to be sent to the dealership, the tow truck guy removed the rear seat to identify source of fuel smell which had revealed fuel pooling on starting attempt of the engine and the heavy fuel pooling was noted at the fuel pump sending unit. This seemed extremely hazardous for car safety.the fuel was gushing out which spread to the seat and fabric and sent fuel smell and fumes into the passenger compartment. Mercedes quoted $800+ for the repairs and delivered the car promising that the faulty pump and sending unit was replaced. The car did not even make home and broke down before reaching home showing same starting problem. Hence it was towed back to the dealership and this time they are asking another $800+ to replace the second fuel pump which they claimed was working when the car was delivered. Fuel smell still exists in the passenger compartment and the car is not drivable. Dealership did not accept any responsibility for delivering the car without repairing the reported defect and asking double price for a manufacture defect of the car which is a major road safety hazard item and must be considered as a safety recall from Mercedes car company.

Every time the gas tank is filled 100% full (only until gas pump nozzle first click) and the car is being driven for less than 20 miles and parked, I can smell very strong gasoline odor from outside the car. I have tried to find the issue and lifted it up. What can be seen is about 1oz of gasoline puddle on rear undercover (underneath gas tank). Other than that, I can see leaked dried gasoline path on the side of the tank, which points to the location of the puddle. This string gasoline odor issue cannot be seen or smelled if the tank is filled only 3/4 of tank volume. This is issue has been reported to Mercedes Benz service at columbia, mo. However, they quoted $600 just to find the issue, even though this is clearly manufacturing defect, since hundreds of similar cases can be found at several forums and so many has been reported here.

Purchased 2007 E350 wagon June 16 2014, upon first refill of fuel tank noticed the smell of gasoline inside automobile. It dissipates over time. On 30 June, purchased second full tank of fuel and noticed same issue and began research. I discovered this has been an endemic issue with the fuel pump and fuel tank. Am researching recalls and taking to trusted mechanic today to get to the root cause. Fuel vapors are highly volatile and I will contact Mercedes Benz to register my complaint. Will keep you updated. The current multi-billion GM recall is a similar issue that corporate leaders ignored for years and now paying a dear price. Will engage mb of na in a deliberate and dogged manner until resolved.

Strong odor of gas in home garage after filling the tank. Since December 2012 I have not been able to fill it over three quarters of a tank without the strong odor reoccurring. I took it to be serviced and after one week of trying, they were not able to find the source. I purchased the car on December 11, 2009.

Fuel gauge showed 3/4 tank, car stopped, mechanic told us the car was out of gas. I spend $600 at the shop to find out this. They first wanted to replace tank, fuel pump and senders. Gas gauge is not working proper, any advise?
