Other Fuel System Tank Filling/charging problems of the 2011 Mercedes Benz E350

Strong gas odor after filling and for few days took it for repair find the sending unit cover leaking it had filled the cover and part of the tank. The odor was on and of about six months ago but only it was getting worse lately and needed repair. I think mercedes company should take this safety issue seriously before major . . . .

When filling up the gas tank, there is a strong gasoline smell inside and outside the car. Mercedes has extended the warranty on previous years and other models but has not extended the warranty to 15 years for this defect to the 2011 E350.

After filling my car with gasoline, I noticed a strong swell of gasoline in my garage when I parked my car. I had never experienced the smell of gasoline in my garage after filling up my gas tank in the past. I left the car in the garage for awhile, but returned to a stronger smell of gasoline. I took the car to mercedes-benz of beverly hills in California for inspection and diagnosis. The service advisor informed me that the fuel filter sensor was bad, and it may be covered under the manufacture's free recall due to a faulty fuel filter sensor. The service advisor informed me that he had numerous customers with cars needing repair recently for fuel leak related malfunctions. He also stated that he had a car with a similar problem as mine being worked on the same day I brought my car in for service. The service advisor later called me and stated that my car was not covered under the free recall for the fuel filter sensor, and that it would cost me $1,100. 00 to repair the car. The service advisor also stated that my car was not covered under the free recall because it has a medal gas tank instead of a plastic gas tank. What difference does it make whether the gas tank is medal or plastic if the part is defective? I checked out this website and found that several complaints have been filed for the same malfunction with the fuel filter sensor causing gas to leak. I have been a loyal customer of mercedes-benz for the past 12 years (I've owned two mercedes-benz thus far). I will think twice about purchasing another mercedes-benz in the future if they do not honor the free recall for my car for this defective part.

After filling up the gas tank, there was a strong fuel odor in and around the vehicle. The dealership diagnosed the problem as a defective fuel sending unit/pump top cover.

All of a sudden, one day after filling my tank, there's now an overwhelming gas smell present both ~20 feet away from vehicle, and inside the car. It is so bad, I have to leave windows down for 20-30 minutes while driving before the environment becomes tolerable with the windows up. I have read that other similar E350 models have this problem, but my newer (2011) year model doesn't appear to be on the extended warranty repair list. I believe I have exactly the same issue others have described because the smell of gas is very strong after a top-off, and gets gradually better, becoming much less noticeable as fuel tank level approaches 1/2 tank and below.
