Also I have had the exact same thing happen to me in the recall dated 3/15/2013. After taking a long trip up to san francisco when I got home my oil tank was leaking -there was a strong odor of gasoline coming from my backseat. I took it in to the dealer they replaced my fuel tank but before they did that they sent me on the road without fixing and no rental car. I thought I would pass out from the smell of gasoline. The dealer told me to roll my windows down when driving what? I drove my car like that for approx 1 week before the fuel tank came in. They did pay for it. I was concerned if I where to smoke in the car what would happen?

Car smells like gas. Constantly a couple machanic. Did some repairs. But there's a small leak as well from a smoke test. Gas leaks in more than one area. Oil leaks everywhere. Evap leak didn't pass smog. Then went to a smog station and repair. Check engine light back on again. I saw Mercedes had an extended warranty to avoid recalling several safety complaints. I got the car from a guy who never looked into recalls or extended warranty for these complaints. Please help me to get refunded what I payed so far with repairs on gas leaks. Also to repair the whole gas system. It is dangerously ongoing. I never got notified by Mercedes nor did the previous owner.

the car has smelled like gas from the minute i received it. the previous owner told me that mercedes had quoted 5 grand to fix it so i would only put half a tank in at a time. turns out there was a warranty on it but has since expired. why wasn't it fixed for free when the previous owner brought it? this is very dangerous and can cause an explosion. the warranty should have been fixed rather than quoted and seems very greedy to not disclose that information but instead giving a quote. i have lung and heart problems and this is a definite safety issue that needs to be corrected regardless of the age of the car also brought it to dealership scared and they told me too bad it's been too long. how is a gas leak an ok thing to dismiss?????? i have been trying to get this fixed for years and this is my 2nd attempt for a recall with no response at all
My vehicle started puttering and finally shut off. I had it towed to the nearest Mercedes Benz shop located on independence drive in charlotte. After the diagnostic, I was told that the fuel pump was bad. I informed the service advisor colton and the service manager todd about the extended warranty on the components of the fuel system. I was denied warranty coverage because they stated that the fuel tank had to be cracked before they would honor the warranty. To my understanding if the item is a part of the fuel system components, it should be covered for the warranty. They refused to satisfy the warranty and I ended up not authorizing the repairs. Now because Mercedes will not repair the covered part, I have to take it to another repair shop to have it fixed. …
This vehicle has a very strong gasoline smell after I fill the tank. This smell is concentrated on the driver side by the rear wheel. I do not have the money to repair or diagnose the vehicle. Although, Mercedes has issued an extended warranty to 15 years unlimited miles for "covered fuel tank components". The Mercedes dealerships are not able to tell me what the severity or the specific reason for my fuel leak/smell without paying a large diagnostic fee/ w no guarantee of warrantied service. I would like them to share specific information about this problem with me without charging diagnostic fee.
