Purchased used 2013 Honda CR-V AWD EXL now has 100700 miles. Runs great no complaints except recently when parked, I smell gasoline around the backend of the car, have not seen anything on the ground, can not smell it in the car, makes no difference with fuel level, no difference in fuel mileage, it's never good only short trips taking the wife to dialysis & doctors. Looking for suggestions I don't really want to have the dealer disassemble the car looking for the problem. any suggestions?? thank you.
