NHTSA Complaint #10574640 — 2007 FORD F-150

HAD A BAD MISS AT HIGHWAY SPEEDS AND LIMPED HOME 15 MILES. REPLACED SPARK PLUGS AND IN THE PROCESS BROKE TWO IN THE HEAD. ONE DID NOT BREAK COMPLETELY OFF (#4) AND I NEEDED TO BORROW A PROTOTYPE TOOL FROM LISLE TOOL CORP. REMOVED AND REPLACED PLUGS FOLLOWING FORD PROCEDURES. TRUCK STILL HAD A MISS. REPLACED ALL EIGHT COIL PACKS WHICH FIXED THE PROBLEM. TOTAL COST$380.00. TRUCK DOWN FOR 6 DAYS AWAITING TOOLS AND PARTS. DEVELOPED A VIBRATION AT HIGHWAY SPEEDS. ORIGINAL TIRES(PIRELLI) WERE SEPARATING. REPLACED TIRES(976.00), MUCH BETTER. STILL HAVE SLIGHT VIBRATION AT HIGHWAY SPEEEDS. FOUND LEFT FRONT HUB BEARING SEEPING GREASE AND FEELS STIFF. AWAITING PARTS TO DO REPAIRS. (98.00) HAD A TRANSMISSION SHUDDER AT LIGHT LOAD IN OVERDRIVE. FLUSHED TRANSMISSION WITH BG PRODUCTS AND FLUSH MACHINE. ADDED NEW TRANS FLUID AND CONDITIONER. TRANSMISSION NOW SHUDDERS AT ALL SPEEDS WHEN HOT. WILL ORDER NEW FILTER AND REPLACE. WILL ADD FRICTION MODIFIER AND TRY AGAIN. HAVE TO TOW ANOTHER VEHICLE THIS WEEKEND AND AM AFRAID TO DO SO. I AM COMPLETELY BLOWN AWAY THAT THESE PROBLEMS COULD HAPPEN TO ANY VEHICLE STARTING AT 48,000 MILES. ALL MAINTENANCE HAS BEEN PERFORMED WITH TOP OF THE LINE PRODUCTS. HAVE BEEN A FORD OWNER ALL MY LIFE AND AM COMPLETELY DIS-SATISFIED WITH THE PERFORMANCE OF THIS SUPPOSED NUMBER ONE SELLING TRUCK. THE STICKER PRICES OF THESE TRUCKS SHOULD BE A BUNCH LESS SINCE CHEAPLY PRODUCED CHINESE PARTS ARE SO PREVALENTLY USED. NOT HAPPY. *TR
