NHTSA Complaint #10717332 — 2007 FORD F-150

THE ENGINE WAS REPLACED IN 2012 WITH 53,000 MILES ON THE TRUCK DUE TO A SIGNIFICANT KNOCKING COMING FROM THE ENGINE. THE TRUCK WAS STILL UNDER WARRANTY SO IT COST ME NOTHING TO REPLACE. THE ENGINE STARTED TO MAKE THE SAME SOUND IN FEB 2015 (84,000 MILES ON THE TRUCK, 30,000 MILES ON THE ENGINE). I HAD IT TAKEN TO AN AUTO MECH AND THEY TOLD ME ONE OF THE SPARK PLUGS EJECTED FROM THE ENGINE AND RIPPED ALL THE THREADING OUT. THEY ALSO FOUND THAT ON E OF THE CYLINDERS BROKE OFF THE CRANK SHAFT AND CEASED. THE ENGINE HAS TO BE REPLACED AGAIN AND THE TRUCK IS NO LONGER UNDER WARRANTY. BOTH THE ORIGINAL DEALERSHIP THAT REPLACED THE ENGINE AND THE AUTO MECH THAT I HAD THE TRUCK TAKEN TO, ARE RESEARCHING IF THE PARTS ARE STILL UNDER WARRANTY.
