| Problem Category | Number of Problems |
|---|---|
| Fuel Hoses Lines/piping And Fittings problems | |
| Tank Assembly problems |
After refueling and filling the fuel tank, a strong odor of gasoline emits from the outside of the car and inside the car. After checking online, previous complaints of fuel level sending unit seal failure causing pooling of gasoline around the sending unit next to electrical connectors and directly under the left rear passenger seat. I removed the rear seat and access panel to the sending unit and discovered pooled gasoline around the sending unit. The sending unit appeared tight. I did not notice any cuts or failure to the hose, just around the sending unit itself. My local mercedes dealer claimed there are no recalls for this condition, even though there appear to be many complaints. The dealer also told me I would have to bring my car in to be inspected by a mechanic to truly diagnose the issue.
I currently drive a 2004 mercedes e500 4matic with 78,000 miles currently on it. Recently, after refueling the car I have noticed a very strong odor of gasoline both inside and outside of the car. After having the same issue after filling my tank about 3 times I decided to do some research on the issue. With not much searching I found a flood of complaints from mercedes owners claiming the exact same issues. From what I have gathered it sounds like its a safety concern and is a design flaw.
