NHTSA Complaint #10459379 — 2011 FORD F-150

WHILE ENTERING A HIGHWAY VIA AN ON-RAMP DOING ABOUT APPROXIMATELY 45 MILES PER HOUR I ATTEMPTED HARD ACCELERATION TO PICK UP SPEED AND MERGE IN TO TRAFFIC THAT WAS DOING APPROXIMATELY 65-70 MILES PER HOUR. WHEN I DEPRESSED THE THROTTLE THE VEHICLE DID NOT ACCELERATE, BUT IT STARTED TO HESITATE AND SHAKE. THE CHECK ENGINE LIGHT CAME ON AND THE VEHICLE WOULD NOT GO OVER 40 MILES PER HOUR. THIS ALMOST CAUSED AN ACCIDENT SITUATION AS I EXPECTED THE VEHICLE TO ACCELERATE WHEN IT DID NOT. I WAS THEN FORCED TO PULL OVER TO THE SHOULDER AND SHUT THE VEHICLE OFF. AFTER RESTARTING THE VEHICLE THE CEL HAD CLEARED AND THE VEHICLE WAS OPERATING NORMALLY. NO CODE WAS STORED IN THE PCM TO INDICATE WHAT THE ISSUE WAS. THIS HAPPENED SEVERAL MORE TIMES SINCE THE FIRST INCIDENT. ONCE WHILE TOWING A 4000LB BOAT/TRAILER WHICH ALSO ALMOST CAUSED A SEVERE ACCIDENT. FORD HAS FOUND NOTHING WRONG WITH THE VEHICLE AND CONCLUDES THERE IS NOTHING THEY CAN DO SINCE NO CODES WERE STORED. I WILL NOTE THAT AFTER RECEIVING TSB 12-2-10 THE VEHICLE WILL STILL EXHIBIT THE SAME SYMPTOMS DESCRIBED ABOVE, BUT NOW THE CHECK ENGINE LIGHT DOES NOT COME ON. VEHICLE WILL STALL, GO IN TO "LIMP MODE" WITH NO INDICATION THAT ANYTHING IS WRONG. ONLY RESOLUTION IS TO TURN THE VEHICLE OFF AND BACK ON TO CLEAR THE STATUS. THIS CREATES DANGEROUS SITUATIONS WHEN ON A HIGHWAY. COMPLETELY UNACCEPTABLE. *TT
