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.

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. Mercedes of palm spring like to charge us $256 just to look at the car so we took our car to another repair shop and they stated that the fuel tank has a problem as the other models and our car is the 3rd merdeces that they inspected with the same problem that week. At this time Mercedes is refusing to repair this on a warranty and as I stated this is a safety issue. I believe this is a very serious safety issue.
