AFTER FUELING MY CAR, GASOLINE SMELL BECAME INTOLERABLY STRONG. I CALLED THE DEALER AND THEY TOLD ME THAT THE 2007 E350 IS KNOWN FOR LEAKS AND I SHOULD BRING IT FOR A DIAGNOSTIC CHECK. THE MANUFACTURER ACCORDING TO THE DEALER IS AWARE BUT NO FEDERAL ACTION HAS BEEN MANDATED. ESTIMATES COULD RANGE FROM $1000 TO $2000. BUMMER. *TR

GAS LEAK WHEN FUELING CAUSING GASOLINE FUMES IN THE VEHICLE. VERY DANGEROUS!! *TR
AFTER FUELING CAR, THERE IS A STRONG RAW FUEL SMELL THAT PERMEATES THE CAR. IT WILL LAST FOR ABOUT 40 MILES THEN WILL SUBSIDE. IF YOU HAVE NOT DRIVEN SUFFICIENT MILEAGE BEFORE PARKING, THE SMELL CAN LAST FOR DAYS, WEEKS AND/OR MONTHS. IF THE CAR HAPPENS TO BE PARKED ON AN INCLINE, THE FUMES ARE STRONG ENOUGH TO KEEP YOU OUT OF THE CAR. *TR
