NHTSA Complaint #11420341 — 2015 MERCEDES-BENZ C300

Heavy fuel/gasoline smell around engine bay began approximately 2 years ago while the car was still under original 5 year warranty. Fuel smell would persist outside of the vehicle despite the vehicle not being driven for multiple days. When driven, fuel smell would permeate into the cabin of the vehicle and cause mild headaches to the occupants. Taken to dealer to find cause of smell and was advised that there was nothing wrong with the vehicle. Fuel smell continues to persist since it was originally noticed without change and vehicle is no longer within warranty period. Recently, this vehicle was taken back to the same dealer for servicing for an unrelated issue. Told the service representative that there was a fuel smell that continues to linger around the vehicle when parked and inside the cabin. This inspection revealed leaks from two fuel lines and technician recommended replacement. Warning lamps, messages, or other indicators from the car never appeared.
