One problem related to other fuel system tank assembly has been reported for the 2012 Mercedes Benz GL450. The most recently reported issues are listed below.
There is a strong odor of gas coming from the back drivers side wheel when parked and when driving. We haven't found any gas on the floor of our garage but definitely a strong gas smell and fumes. We have tried to fill the tank 1/2 way but it doesn't seem to help the smell/fumes are throughout our entire house including the 3rd floor when the car is parked in the garage. I am worried about it exploding or catching on fire. I have read online of other mercedes leaking gas and wonder if this is happening to anyone else who owns a gl 450?.
