Open the full vehicle complaint log (all categories)SMELLED GAS WHEN EXITING THE VEHICLE. CONFIRMED A FUEL LEAK IN THE FUEL TANK BY OBSERVING A FUEL DRIP. CONTINUED DRIVING THE CAR FOR A FEW DAYS. ON JUNE 15, 2020, I NOTICED A STRANGE NOISE AS I DROVE, SOMETHING RUBBING OR BUMPING ON THE FRAME UNDER THE CAR. WHILE DRIVING, THE NOISE INCREASED AND INTENSIFIED. I WAS FORCED TO PULL OVER AND CHECK UNDER THE CAR. TO MY HORROR I SAW THE GAS TANK DRAGGING ON THE ROAD. A TOW TRUCK WOULD NOT TOW THE VEHICLE. MY BROTHER AND I TIED THE TANK UP UNDER THE CAR USING A NYLON STRAP TO GET THE CAR HOME. I CALLED THE DEALERSHIP TO FIX THE CAR. I NOW HAVE AN AFTERMARKET TANK ON MY CAR. FORD DOES NOT MAKE THE TANK ANYMORE.THE CAR WAS IN MOTION ON A CITY STREET WHEN THE TANK FELL. I BELIEVE THE PROBLEM WAS CAUSED BY A FUEL TANK STRAP FAILURE. THE FUEL LEAK WAS ALSO DIRECTLY RELATED TO THE STRAP SUPPORTING THE TANK. *TR
GAS TANK FELL DOWN AT HOME IN THE DRIVEWAY. VEHICLE WAS STATIONARY AND FULL TANK OF GAS.
