“Strong gasoline smell when I fill my tank up and park my car inside my garage. So strong that I worry about explosion due to my water heater with pilot light in the garage. I frequently open the garage door to let the accumulated gas odor dissipate or have to move the car outside. Strong gasoline smell goes away once the fuel level goes down about 1/8 to 1/4. This has been going on since 12/20/2020.”
NHTSA complaint #11407529, filed 2021-04, 41,000 miles“Strong smell of gasoline when tank is filled up. This has been an ongoing issue for a few months now. Don't know much about cars so didn't think much of it until I had a couple of people ask why my car smelled like gas. They let me know that it may be a gas leak somewhere.”
NHTSA complaint #11362142, filed 2020-10, 154,000 miles“Fuel tank leak- smell gas in car and outside car. Received notice of airbag recalls and light issue as well. Main concern is gas smell emanating from my car. This happens mostly when I fill the tank.”
NHTSA complaint #11145272, filed 2018-11, 83,000 miles“Our 2010 mercedes C300 with 24,500 miles car started to sell gasoline appx a week ago. We found out that mercedes has similar problems with their other cars and I believe this is a very serious problem since it involves gasoline. The mercedes dealer stated that our car does not have a recall for this problem even though it has the same problem as the other recalled models. The smell is constant and we cannot even park our car in our garage due to the fumes and strong smell. …”
NHTSA complaint #10893094, filed 2016-08, 24,000 miles“The check engine light comes on dealing with the catalytic converter/fuel system. The sensors are off causing the emission of too much gas. The car runs out of gas fast and does not drive well to get good gas miles per tank. The car's exterior lights also go out fast. This should not happen with a top of the line mercedes car.”
