There is a strong odor of gasoline coming from the drivers side rear. I conducted a Google search on the issue and there are a lot of instances of the same thing. It appears to be the Gas Tank Sending Unit, they have a tendency to crack and leak.

Park in the driveway. 4. Take rear seat out(pull up on the leading edge of the lower cushion...there are 2 tabs to depress then the seat comes up) 5. 8mm socket and take the drivers side
The vehicle sunroof exploded while traveling on the interstate. Stopped and inspected the vehicle to find no impact objects inside the vehicle. Later reviewed online that this was a common problem with this modern Mercedes and the item is already under recall but not my year. I have a 2012 and the recall stops at 2011 although 2012 sunroofs are exploding too
