NHTSA Complaint #10907667 — 2009 FORD FLEX

VEHICLE DOES NOT RECOGNIZE LAST QUARTER TANK OF FUEL. ONCE IT REACHES APPROXIMATELY A QUARTER TANK LEFT, THE FUEL GAUGE AND MILES TO EMPTY DISPLAY DROP SUDDENLY TO EMPTY AND THE CAR SHUTS OFF. WHEN REFUELING AFTER IT SHOWS EMPTY, IT ONLY ACCEPTS ABOUT 3/4 TANK. THE FUEL IS THERE, BUT INACCESSIBLE. THIS IS A MAJOR SAFETY ISSUE AS THE CAR DIES VERY SUDDENLY WHEN THE SYSTEM DECIDES THERE'S NO FUEL LEFT. IT HAS HAPPENED ON THE INTERSTATE, OTHER HIGHWAYS, AND ON A RURAL ROAD WHERE FINDING ENOUGH FUEL TO GET GOING AGAIN WAS A BIG PROBLEM. DEALERSHIP REPLACED FUEL SENSORS, BUT SAID THERE WAS NO CODE SHOWING WHILE THE CAR WAS STILL UNDER WARRANTY. NOW I'M STUCK RANDOMLY REPLACING FUEL SYSTEM PIECES IN HOPES OF FIGURING OUT WHICH PIECE IS BROKEN. EACH TIME I SPEND HUNDREDS OF DOLLARS TO "FIX" IT, THE PROBLEM REPEATS AS SOON AS I GET THROUGH MOST OF THE FIRST TANK OF FUEL. POSITION OF VEHICLE DOESN'T MATTER. UPHILL, DOWNHILL, ETC, IT ALWAYS HAPPENS CLOSE TO A QUARTER TANK OF FUEL LEFT.
