2007 Mercedes-Benz AMG E63: gas smell in the cabin

Filed Jan 22, 2024 · Fuel system · FL

VIA REGULAR MAIL AND ONLINE SUBMISSION RE: VIN # [XXX] – Mercedes Benz 2007 E 63 – We would like to bring to your attention the failure of the Fort Lauderdale Mercedes Benz dealership to properly honor the repair and replacement of parts and labor covered under a recall for Fuel Tank Components for MODEL 211 (E-Class) years 2003-2009. A copy of the Recall notice which provided for an extension of the Recall thru 01/31/2021 is attached. Also attached please find a recent repair invoice for the respective repairs which should have been repaired under this recall. Mercedes Benz undertook a “partial” repair of the parts covered under this recall and at the time of that repair failed to properly repair all of the parts related to this issue/recall. Instead, they only replaced one fuel tank/fuel pump while the extended warranty coverage was in place and left the issue to materialize/manifest in the remaining fuel pump/tank despite the fact that conditions indicated it would likely fail in the near term at the time of the partial repair. Of further concern is the fact that an active Recall for the exact same item exists and remains active for later model years. Clearly, they have not fixed the cause of failure for this vital car part and continue to place drivers/owners at considerable risk. the federal safety agency – ODI It is incredulous to me, a 25+ year dedicated Mercedes Benz customer that an experienced dealership would attempt to evade responsibility for such a significant safety recall item. When this issue exists, the smell and fumes of petroleum/gas can be easily smelled from the exterior of the car. If you were to light a cigarette – you would likely cause the car to explode. When this issue existed, the interior cabin of the car would fill with petroleum/gas fumes again placing the driver at considerable risk. Please review the attached documentation and require Mercedes Benz to acknowledge that their half-hearted repair done during the recall INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

I filled up the gas, took a short drive home, and parked in the garage. Next day, there is a strong gasoline smell in the garage as well as inside the car. This happened whenever I filled up the gas since then.

There is a strong smell of gasoline over 1/2 tank full, and frequent check engine lights on for an evap system leak. This is a known issue with these cars, and I am concerned to drive the vehicle with gasoline fumes coming inside the car and creating a fire hazard. Mercedes knows about this problem and needs to address it.

I purchased this car late july 2012 and when I went to pick it up I noticed a slight smell of gas from the left rear of car but, didn't think much of it as it was a new to me vehicle, just thought it was freshly filled up. The next time I filled up I noticed that the car smelled both inside the car and outside the car. As a new owner of a newer mb I joined mbworld form and searched this problem with e55 and e63 and found that it is a common problem for the w211 cars. Also, it seems the solution is not as obvious as one would think. On nov 14, 20012 I took it to cal star motors in glendale ca (a mercedes dealer) for repair, they told me that the cause of the problem is the seal between the sending unit and the gas tank. They replaced this part and I drove the car home as I needed to bring in car with half a tank for repair I did not notice any issue. Next time I filled up there was no smell from inside cabin and only slight smell outside. I now have filled up several times and the problem has returned. I should say that after fill up there has never been any leaked gas present when parked as I check drive daily for any evidence of leaks in any fluid. I feel that if there is a gas leak issue with this/these cars which it appears there is based on so many issues reported that mercedes has a responsibility to solve the problem as it is a very dangerous situation to leave unresolved.

Strong fuel smell after fill up for over a year. Was brought to mercedes with no fix. Recent inspection resulted in finding a puddle of fuel under the rear seat on the fuel sending unit. Further research shows this is a ongoing problem for other e-class and has been reported to the federal safety agency, and current fixes if any has been failing and even owners having to pay out of pocket for something mercedes should be fixing under warranty due to this serious potential safety and fire issue. I have two toddlers who sit in this car everyday.

Notice a gas smell after filling up the tank. Did not really took it for anything but on the second fill smell again inside the car. Being summer I drive windows down and smell was not bad until I had the AC on. Online research prove it to be the tank. And its a known defect but mb will not fix it. More I check into the problem its an on going issue with these cars. 100k and no one will listen to your issues. I now fill 3/4 as the fix and no issues and can not sell it to someone else knowing this is a problem.

Filled auto with fuel for first time and drove home, parked in the garage and started to smell gas fumes from driver's side passenger seat area. Learned that there is the federal safety agency action number: pe12001 pertaining to e55 which was previous year model to mine. Threat of fire under where my child sits is unacceptable. My early model e63 with same fuel issues should be covered. Please cover this model and model year as well!

Filled my car up with gas and after driving it home there is a very strong fuel smell coming from the car. Looking online I see that many people with the e63 amg cars have also experienced this, and it is a faulty fuel sender unit that is literally leaking fuel out.

I reported to my independent mechanic a strong fuel smell when filling the vehicle full and parking it. Upon further investigation, my mechanic discovered a fuel leak from the drivers side of the tank onto the left exhaust which of course can create a fire hazard. I immediately contacted my local mb dealership and spent days trying to get in touch with the service manager. Finally after contacting the mb central region office, I left a vm and was contacted by the service manager I had been trying to get in touch with. As of today 4/8/13, I took the vehicle in for inspection. They told me that the drivers side fuel sending unit/pump is leaking and would need to be replaced. I asked if the car was safe to drive, they replied no, but happily sent me on my way anyhow. This problem lines up with every other complaint about the my03-09 w211's that exhibit this problem. I have not had the fuel leaking to the ground and pooling up, but the dealership has confirmed that the sending unit is indeed leaking and pooling up in the depression where the sending unit attaches to the tank, which is now leaking onto my drivers side exhaust, thus creating potential for a fire hazard. The federal safety agency action number: ea13003.

Normal fill up of gas tank causes fuel to leak out of top of sending unit. The seam just below the electrical connection powering the units motor seems to be weakly and/or improperly joined, allowing raw gas to leak out and pool into a small compartment under the drivers side rear seat. When I purchased car used 14 months ago, I noticed extreme gas smell after 1st night in the garage. I immediatly took vehicle back to dealer where they replaced sending unit under 30 day warrenty. Now only 14months later after a normal fill up at a gas station and then driving home, I noticed a very strong gas smell as I entered the garage the next morning. I have found that I am not the only one with this issue. Online research lead me to information that gave me the details neccesary to locate and remove the access panel under the drivers side rear seat. After removing the top access panel under the seat I found (rough estimate) a measuring cup of gasoline that was pooled around the base of the sending unit. So much fuel had leaked that it had overflowed the pumps recess and had pooled into the surrounding (rubber/plastic) recess that seals the top of the sending unit from the outside.

I had just purchased the car the day before (april 28, 2012). When I filled the fuel tank, I notice a strong smell of gasoline. This has occurred every time I fill the car with fuel. At first I thought it was a fuel injector leaking down and something I would have to address in the near future. However, last week I went to drive the car after I had just filled the tank with fuel. The car was in my garage and the smell of gasoline was very strong. I noticed a puddle of fluid in front of the left rear tire. My first reaction was it was condensation from the air conditioning system. I bent down to look at it and then I notice a separate condensation tail coming from the middle of the car. I sampled the fluid stream from the middle of the car and indeed it was water. However when I looked at the other puddle, I notice a constant and rapid drip coming from the shield under the gas tank. When I sampled the puddle it was pure gasoline. This was most disconcerting as this fuel leak is very close to the exhaust and the brakes. Either one of which could ignite the fuel. I am a mechanical engineer with considerable auto racing experience, so I know how dangerous this can be. I called mercedes benz of sugar land on monday (11/12/12) and talked to a service representative. I told him of the fuel leak and he told me there was no reported issues and no service bulletins for such a problem. I was also told to bring the car in and they would repair it at my expense. Having paid my way through my first degree as a mechanic as well as designing racing equipment for ford motor company, I believe this should be covered under warranty as part of the emission system. This is of course secondary and in addition to the obvious safety hazard this condition presents.
