THE FIRST TIME THE ACCELERATION ON MY F150 STUCK, I WAS ON A COUNTRY ROAD. I WAS BRAKING ON A DOWN HILL TO A STOP SIGN. I MADE SURE I WAS NOT DOUBLE PEDDLING AND THEN SLAMED DOWN ON THE BRAKE PEDDLE. I HAD PLENTY OF SPACE BEFORE THE STOP SIGN AND SLAMMING THE BRAKE REGAINED THE CONTROL. I DID NOT REPORT THIS TO MY FORD DEALER. I DID NOT KNOW THAT IT WOULD BE AN ISSUE. APPROXIMATELY 4 MONTHS LATER THE TRUCK DID IT AGAIN. THIS TIME I WAS BACKING UP AND HAD MY FOOT ON THE BRAKE PEDDLE AGAIN. I DID NOT HAVE ENOUGH TIME OR SPACE TO REGAIN CONTROL AND I STRUCK A TREE, WHICH STOPPED THE VEHICLE. IT CAUSED MAJOR DAMAGE TO THE TAILGATE, BUMPER, LIGHT ASSEMBLY, AND PASSENGER SIDE BED FENDER. I PARKED THE TRUCK AND WALKED AWAY FOR SEVERAL HOURS. WHEN MY HUSBAND WENT TO MOVE THE TRUCK, THE BRAKE PEDDLE SANK STRAIGHT TO THE FLOOR, LIKE THERE WAS A LOT OF BRAKE PEDDLE MOVEMENT AND NO BRAKE PRESSURE. I DO NOT BELIEVE THE GAS PEDDLE WAS STICKING, MORE LIKE THE COMPUTER WAS ACCELERATING WHEN THE GAS WAS NOT ENGAGED. MY FORD DEALERSHIP RAN DIAGNOSTICS THAT DAY AND IT HAD NO CODE ISSUES. FORD LEGAL RETAINED THE TRUCK AND RAN DIAGNOSTICS AGAIN 3 MONTHS LATER AND AGAIN NO CODES. STILL DO NOT HAVE AN ANSWER TO WHAT CAUSED THE ACCELERATION ISSUE. FORD SAID THERE WAS NO ISSUE WITH THE BRAKING SYSTEM. I WOULD VERY MUCH LIKE TO KNOW IF THERE HAS BEEN SIMILAR OCCURRENCES WITH OTHER 2018 F150'S.
