FUEL/PROPULSION SYSTEM
Head lights suddenly went out while driving at night causing near accident, happening frequently. Also, the gas tank leaks when I put gas in car, making it smell badly and making it dangerous if someone drops a cigarette near it.
NHTSA complaint #11612352 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
While driving, I came to a stop light and suddenly, the car idled high and lurched forward while my foot was on the brake, luckily, I was stopped well away from the vehicle in front of me. The car idled high and seemed to have a mind of it's own. I took the back roads home and backed into our garage. The car smelled hot, and I though I had smoked my brakes, trying to keep control of it. Later that night, I told my husband about the car's actions and he did not believe me, though my daughter who was with me at the time confirmed that the car had indeed accelerated on it's own. My husband started the car and it did idle high and get hot once again, although only parked with no one in it. He thought he knew what the problem was and we turned off the car and closed the hood and went inside to order the part. A few minutes later, we heard a couple popping noises and I opened the door that led into the garage from the basement. Smoke was coming into the house and my husband said that a flame shot over my head. The car had caught on fire under the closed hood. We called the fire department, but by the time they arrived, a good portion of the basement was on fire. The house was a total loss. My husband though that the pvc elbow under the hood was sticking closed, so that is the part we were going to order. Unsure, if that was the real cause or not. The car did not have any warning lights or any other indications of a problem before this incident.

FUEL/PROPULSION SYSTEM
?yrs.ago While backing out of parking space at Calaveras Lumber, after shifting into reverse, & removing my foot from the brake; the engine appeared to receive a huge burst of fuel which shot me backward like a rocket slamming my vehicle into and wedging it under the frame of a pickup truck parked in the same lot. I am glad I was parked and had my foot on the brake prior to this unit or system malfunction otherwise the injuries could easily have been fatal on the highway. I think this defect may be a contributing factor to the car dying recently while on my way to a Wedding Reception in Roseville, which left me stranded after dark for 41/2hrs and 71/2hrs. 2days later. I have not been able to start vehicle since and mechanics unable to diagnose why the engine is fuel starved when system parts tested appear to be in good working order. Something seems to be shutting off power or preventing power to the fuel pump and it is not the inertia switch, relays, fuses etc.. Components have been previously inspected by numerous others including dealer. No Recognizable Alert/Warning Prior to Incidents!

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
WHILE ENTERING ONTO THE WOODROW WILSON BRIDGE FROM I-295S ON 2/1/2018, I PULLED INTO THE CENTER LANE AND BACKED OFF THE GAS PEDAL, BUT THE CAR CONTINUED TO ACCELERATE ON ITS OWN. LUCKILY THE TRAFFIC WAS LIGHT, AFTER HITTING THE BRAKE AND THE OFF BUTTON FOR THE CRUISE CONTROL, TO NO EFFECT, I WAS ABLE TO PULL INTO THE RIGHT LANE AND TURN THE CAR OFF. WHILE STILL IN MOTION, I TURNED THE KEY BACK ON AND EVERYTHING WAS NORMAL AGAIN. SINCE IT WASN'T A CRUISE CONTROL ISSUE, IT WOULD APPEAR IT IS SIMILAR TO THE TOYOTA PROBLEM WITH THE DRIVE BY WIRE ISSUE.

NHTSA complaint #11058425 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
I WAS DRIVING AT A SPEED OF 45MPH ON A COUNTY ROAD IN RUSH HOUR TRAFFIC WHEN MY CAR'S ENGINE LIGHT CAME ON SIMULTANEOUSLY AS POWER OF VEHICLE SLOWED WHILE MAKING A RATTLE TYPE NOISE AND CAB SMELLED STRONGLY OF GAS. I ROLLED WINDOWS DOWN PULLED OVER WITHIN A BLOCK TO A NAPA STORE. THE EMPLOYEE TOLD ME THEY DO NOT RUN DIAGNOSTICS AND I WOULD HAVE TO TAKE IT SOMEWHERE. I DROVE SLOWLY TO A 2ND AUTO PARTS STORE 1 MILE AWAY TO RUN DIAGNOSTICS. ONCE DONE, DIAGNOSTICS IDENTIFIED A MISS-FIRE ON SPARK PLUG #2. HAD VEHICLE TOWED TO HOME AND TOOK 'HELI-COIL' OFF AND SPARK PLUG CAME OUT WITH IT DAMAGED. THE HELI COIL WAS ALSO DAMAGED. THE THREADS OF SPARK PLUG WAS FLATTENED THREE THREADS FROM BOTTOM. CONTACTED AUTO PARTS STORE AGAIN WHERE THE TECHNICIAN TOLD ME THAT FORD HAS BEEN HAVING PROBLEMS WITH THERE TRITON SPARK PLUGS BLOWING OUT ON THE 5.4L ENGINES THAT THEY ONLY SCREW IN 3 THREADS INTO THE HEAD OF THE ENGINE AND THERE WERE PENDING LAWSUITS. THE NEXT DAY I CALLED FORD DEALERSHIP AND SPOKE WITH THE ACTING SERVICE MANAGER. "HE TOLD ME THERE WAS NOTHING HE COULD DO ABOUT IT AND I SHOULD CALL CUSTOMER CARE OF FORD: 800-392-3673. I DID AND REP. TOLD ME THERE WAS NO RECALL AND MY VEHICLE AND IT WAS OUT OF WARRANTY AT 101,100.MI. THERE WAS NOTHING THEY COULD DO. IN THE EVENT THERE WERE TO BE A RE-CALL TO SAVE MY RECEIPTS AND FORD WOULD REIMBURSE ME. I READ ABOUT THE PROBLEMS THAT MULTIPLE CUSTOMERS WERE OR HAD HAD REGARDING THE SAME PROBLEM WITH A FEW VEHICLES LEAKING GAS WITH THE PROBLEM. THIS IS ALL HAPPENING WHEN THE CARS, TRUCKS AND SUVS EXCEEDS 100,000MILES. I FEEL THIS IS NOT ONLY POOR MANUFACTURING OF AN INFERIOR ALUMINUM CASING AND SPARK PLUG AND ALSO NOT ENOUGH THREADS TO HOLD THE SPARK PLUG IN SAFELY. TO HAVE IT JUMP OUT ALLOWS GAS TO ALSO BE EXPELLED ONTO THE CARS REMAINING PARTS AND VAPORS COULD IGNITE CAUSING THE CAR TO POTENTIALLY CATCH FIRE.

FUEL/PROPULSION SYSTEM
THROTTLE BODY FAILURE__ ENGINE GOES TO DEAD IDLE AT HIGHWAY SPEEDS, LEAVING THE DRIVER AND PASSENGERS HELPLESS TO EXIT ONTO THE BREAKDOWN LANE OR SHOULDER IF YOU ARE NOT IN THE RIGHT HAND LANE WHEN IT HAPPENS, IE IF YOU ARE ON A 70 MPH INTERSTATE IN THE CENTER LANE WITH VEHICLES PASSING YOU ON BOTH SIDES WHILE YOU ARE HELPLESSLY COASTING TO A STOP UNABLE TO REMOVE YOURSELF FROM THE CENTER LANE, YOU WOULD BE SUBJECT TO CAUSE A CHAIN REACTION ACCIDENT. FORD REFUSED TO FIX THIS VEHICLE AT THEIR EXPENSE, AND WANTED TO CHARGE ME $189 DOLLAR FEE TO ANALYSE THE PROBLEM, WHEN THEY ALREADY KNEW WHAT WAS WRONG,(ACCORDING TO THE TECH PERSON I SPOKE WITH WHO SAID THEY HAVE REPLACED HUNDREDS OF THESE DEFECTIVE PARTS) THE PART COST $543 DOLLARS NOT INCLUDING LABOR ON A VEHICLE WITH 71 THOUSAND MILES ON IT. THIS IS AN EXTREMELY DANGEROUS SITUATION AND SHOULD BE RECALLED ASAP
