When the car is cold , no issue. But if I drive and stop for 15 - 30 minutes and restart I smell a little gas. Is this a common issue?

 

Hmmm, an old thread with no replies, but I am having the same issue. 2010 MCS. Seems to clear out fairly quickly, but is that normal?

Might be time to see the dealer.

 

just yank the bottom of the back seat out and make sure the cover above the tank is sealed well maybe?

you just pull up on the front and then out and it pops out.

or maybe look up under the car in that spot and verify there is no leaking fuel... the high presure line clicks in up ontop of the tank, so its hard to say if any drips would reach very far before evaporating
