My Mercedes Benz 2011 E350 smelled like raw gas inside the drivers compartment apparently it was a leak from the top of the gas tank, my daughters 2010 c300 also just went in for the same problem leaking from the gas tank and even soaked the rear seat cushion,even though they repaired it I am worried that it could happen again especially if the parts replaced were not updated, it smelled up my garage and I fear if it leaks again it could start a fire in my garage, please advise. It appears it happens especially when you fill up the gas tank.

Strong smell of gasoline detected. Repair technician identified a fuel tank leak and stated other mercedes effected by the issue. I call mbusa who said they have no recalls or warranty extensions on this make, model and year.

Oil cooler leaking. Repaired on January 2018 ,vehicle had 66724 miles,at mercedes-benz of west houston, even after repair the vehicle still has oil cooler leak. Timing chain rattle , incorrect signal from camshaft hall sensor. Ad-blue tank with heating element code 20b91b. Smell diesel on vehicle. The vehicle has now just 88566 miles .

The stated vehicle developed strong gas fume smell after fill-ups a few months back at around 36000 miles. Unfortunately we left on vacation and later to our second home and missed getting to the dealer before our 7 years extended warranty was over in Nov. 2017. We returned home for the holidays and everytime we fill the tank the same odor reappears making it nauseating in our garage not to mention probably dangerous. I called mbusa and was told it isn't under warranty (funny mine just expired) and to take it to the dealer for an estimate. This is a vehicle that after its 3rd year has hardly been used driving less than 7000 miles in the last 4 years, and that has always been gargae kept. My search in the web has shown a lot of similar issues with Mercedes Benz vehicles, however mbusa told me not mine. This is a serious and dangerous issue that I'm affraid could cause serious damage or bodily injury including death should a spark happen in my garage. Again from my search it appears Mercedes Benz has had similar issues and perhaps hasn't found a complete solution.
