NHTSA Complaint #10819183 — 2011 FORD F-150

UPON DOWNSHIFT DURING ACCELERATION, THE TRUCK SHUDDERS, MISFIRES, BACKFIRES THROUGH EXHAUST SYSTEM, AND LOSES POWER WHILE CREATING A VIOLENT SHAKE IN THE DRIVETRAIN. THIS OCCURS IN BELOW 35 DRY OR WET WEATHER. THIS ISSUE DESTROYED MY CATALYTIC CONVERTERS, AS WELL AS BROKE LOOSE THE BAFFLES IN FACTORY MUFFLER CAUSING OVER $2,000 IN REPAIRS FOR EXHAUST. I FURTHER REPLACED PLUGS, AND PLUG BOOTS. THE VEHICLE CONTINUES TO HAVE THIS SEVERE ISSUE, AND THE ONLY WAY TO KEEP FROM FURTHER DAMAGING THE VEHICLE IS TO PULL OFF THE ROAD, AND IDLE AS WELL AS REV ENGINE FOR SEVERAL MINUTES. IT IS EXTREMELY UNSAFE, AND NEARLY CAUSED OTHER VEHICLES TO REAR ENDED ME ON AT LEAST 5 OCCASIONS. ALL OF WHICH I HAD TO JUMP ONTO SHOULDER OF ROAD OR IN MEDIAN TO KEEP FROM GETTING HIT. MY RESEARCH SHOWS THAT THIS IS A COMMON PROBLEM AMONGST OWNERS OF THIS VEHICLE. I CURRENTLY OWE $22,000 ON THIS VEHICLE, AND AM QUITE FRUSTRATED WITH THE LACK OF A RECALL FROM FORD. SOLUTIONS OF A WALKER CAC ARE KNOWN; HOWEVER, FORD IS NOT WILLING TO EVEN CONSIDER PAYING FOR THIS FIX. PLEASE HELP IN THE RESOLVING OF THIS ISSUE?
