I own a 2007 mercedes e350 and I often notice a strong gasoline smell in and around the car, especially after fueling. Based on internet research this sounds a lot like the complaints many other owners are registering. I have not discussed it with a dealer yet but I am sure any related repairs will be costly. I first started noticing the gasoline smell over a year ago but it was mild and has gotten worse recently.

Noticed that whenever I filled up my tank I smell gasoline inside the vehicle. This always happened anytime I fill my tank.
Fuel is leaking from top of fuel tank when tank is full, causing odor inside of cabin, and fuel to drip onto ground.

[this is only explaining the first occurrence, this has happened a plethora of times since] after stopping at a fuel station and filling the fuel tank from 1/4 to full, we drove on a local road at an average speed of about 30mph for approximately 3 miles. After this we merged onto a major highway where the average speed we were going was between 60-75mph. It was after driving at these speeds for 10 minutes that we started to smell the odor of gasoline in the cabin. Without any other cars in front of us or any noticeable spill [on the road] that we may have passed, there could not have been any other origin of the odor except for the e350. At first it was a low odor of gasoline emanating from under the front passenger side seat, but soon a strong odor of gasoline filled the entire cabin, to the point of forcing us to roll down the windows. The smell did not go away completely but rolling the windows down to allow fresh air to purge the cabin did help. We have taken the car into the dealership multiple times and have requested a complete check-up of the vehicle. The dealership (euro motors of devon hill, pa) has told us that there is nothing wrong with the vehicle (fuel system wise). However, after refueling [especially from the tank being at 50% and then me filling it to 100%] the strong odor returns inside the cabin. It goes away after the fuel levels have dropped from a full tank to 3/4 full, after which the odor does not return when driving the car. I have just heard about other having the same issue and thought I was paranoid. However, it seems that this is endogenous between all other e350s. Please feel free to contact me regarding any diagnostic data that would help you get to the bottom of this.

Gas fumes inside car when parked.
I have a very strong odor of gasoline after filling the tank. I am afraid that my water heater is in the garage with that gas smell it might explode. I took the car to dealer and they said it's normal . But when I checked the consumer complaint online many owners have the same problem. I have to park my car outside when I smell gas in my garage. Please look in to it before someone have to die because the defect. I never own a car before that had that problem and I think this is a very very serious matter.
Strong gas fumes after filling gas tank that will not go away the garage smells strong fumes, people in the car complains of the smell is this safe to smell and be confined within a car or near water heater in the garage. Seems like a hazard to me.

After filling gas tank, strong smell of gas in garage, especially around the rear of the vehicle, as if there was fuel overflow, but there was no fuel overflow at the filling station - did not top-off tank, stopped at first shut-off.
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 $649.00. 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 federal safety agency, the federal safety agency 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 $264.00; 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.

In january, 2009, I purchased a certified used mercedes benz e350 from a mercedes dealer in tuscaloosa, alabama. At the time I purchased my vehicle it had approximately 40,000 miles on the odometer. In december, 2012, I began to notice the smell of fuel in the cabin of my car. The smell was overwhelming and increased over time. At the time I first noticed the fuel smell, my vehicle had approximately 90,000 miles on the odometer and the vehicle was no longer under warranty. I took the vehicle to my mercedes dealer in georgetown, texas, and was informed of the faulty gas seal and was very surprised when they informed me that I had to replace the seal, entire gas tank, and gas lines. To fix the problem, which was now a safety hazard as well as an environmental hazard to the occupants of my vehicle, I had to pay over $3,600 out of pocket to have the repair completed. The repair was completed in an afternoon and I have had no further issues. My complaint is that this is a known safety hazard with the make/model of this car and mercedes refused to fix this known safety issue. Without fixing this problem, the car became unusable.

Gas smell at all times. Greater smell when stored . Engine light came on. Took to the dealer, charged $4,000.00 to repair.
When I put the car in the garage overnight, there is a stronge odor of gas escaping. Engine light continued to stay on.
There is a strong smell of gasoline when vehicle is parked. Took it to the dealer and they indicated there is not a recall for this issue and the tank should be replaced. Researched this and found there are several complaints for this issue that have been lodged. The average benz owner parks their car in the garage. The average homeowner has a gas water heater located in the garage. This is an open flame and gasoline connection which can result in an explosion.
Strong gas smell especially when parked and after fueling.
After I filled up gas and parked for 2 days, I went back to the car and smelled gas odor from the outside and the inside of the car. I drove the car for 78 miles and still smell the gas while driving. I went back and parked, the smell still occurred. When I checked online, there was a lot of complaint about this issue ( fuel sending unit) on this car (mercedes benz wagon 4matic e 350. 2003-2009. ) the gas sending unit has leaked. I think this is a safety issue that the federal safety agency should open up the investigation and conduct a recall about this issue, because I have two children's of my own that sit in the backseat of our vehicle. I will take no chances to drive this vehicle and we still own a payment on it. If this issue is not being investigate, I will take it up to the next level ( national television). I hope this issue will resolve at this level immediately . Thank you [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
