Strong gas smell when car is idling and miles to empty goes down very quickly, approximately a mile or more a minute. There is no recall for this problem and Mercedes is very aware of this problem.

Strong gas odor in the cabin and in motion to the point of causing me to be light headed with my children in the car. Smell of gas coming from the engine when parked. No lights or warnings and it does not occur all of the time just sometimes however ive noticed it 3x the last 5x i have drove my car, the cabin was only extremely bad once.

MB USA extended the warranty coverage on the low pressure fuel hoses that connects to the high pressure fuel pump. The reason is "under certain cold ambient conditions during a cold start of the engine, the low pressure fuel hose at that connection may experience slight fuel weeping". MB USA, however, ruled out a safety risk. NHTSA needs to investigate it. If MB USA found the fuel pressure line is defective, they needed to do a recall. I believe it must be a recall as fuel leaks is not only a safety risk but also a serious health hazard to the occupants. What if the occupants have sinusitis and don't smell well. What if the leaks is too small to smell enough but can still be a health issue.

A fuel line in the engine compartment just above the skid plate on the drives side just right of the front wheel well leaks fuel where the line is crimped coming from the high pressure fuel pump. Fuel collects on the skid plate and when a stop at idea produces a strong fuel smell in the cabin of the car

Exhaust was coming into the car for month. When I started the car to let it warm up in winter months, I would get in and wonder why I smelled gas or fumes. Figured it was from sitting. No dashboard lights came on, no C02 sensors if there are any, nothing came on in the interior to warn me there was an insane. One person told me the part was 'defective' another person told my boyfriend the part was 'split most likely from road conditions' - this put my life and my 10 year old's life at risk. It really needs to be checked out because the C300 coupe is riddled with small iddues
