DURING A 100K MILE TUNE UP, I ATTEMPTED TO CHANGE SPARK PLUGS. OUT OF 3 PLUGS, 2 BROKE OFF IN ENGINE BLOCK. THE TRUCK WAS THEN TAKEN TO A MECHANIC WHO BROKE OFF 3 MORE. THEY TOLD ME THAT FORD IS VERY AWARE OF THE PROBLEM AND WOULD NOT DO ANYTHING ABOUT IT. IT COST ME $800 TO HAVE SPARK PLUGS REMOVED. NOW IT APPEARS THAT A PART OF THE OLD PLUG BROKE OFF INTO THE CYLINDER HEAD, NOT REMOVED BY ORIGINAL SHOP, CAUSING MORE DAMAGE THAT IS CURRENTLY BEING LOOKED AT BY ANOTHER SHOP.
THE ENGINE STOP RUNNING SOMETIMES. IT SAYS "ENGINE FAIL SAFE MODE" NEED TO COMPLETELY STOP AND RESTART THE ENGINE.. THEN OKAY.. IT HAPPENS NOT ONLY ONCE BUT FEW TIMES ALREADY..IT HAPPENS WHEN THE CAR IS IN MOTION..RUNNING AROUND 40 TO 60 MILES MPH.
IN 2012, WE BOUGHT A USED MARK LT WITH 60K MILES. THE VEHICLE SINCE STALLED TWICE AFTER REACHING 100K+ MILES AND DRAINING TWO BATTERY, SHUTTING DOWN THE ENGINE WITHOUT WARNING AT A LOW SPEED AND WHILE TRYING TO TURN. THIS RENDERED THE BRAKES AND POWER STEERING USELESS - WE JUST BARELY AVOIDED FRONTAL COLLISION WITH STREET SIGN…

IN 2012, WE BOUGHT A USED MARK LT WITH 60K MILES. THE VEHICLE SINCE STALLED TWICE AFTER REACHING 100K+ MILES AND DRAINING TWO BATTERY, SHUTTING DOWN THE ENGINE WITHOUT WARNING AT A LOW SPEED AND WHILE TRYING TO TURN. THIS RENDERED THE BRAKES AND POWER STEERING USELESS - WE JUST BARELY AVOIDED FRONTAL COLLISION WITH STREET SIGNS AND A BRIDGE AS WELL AS ALMOST BEING REAR-ENDED BY DRIVER BEHIND US. FORTUNATELY, BOTH WERE AT LOW SPEED AND ON LOCAL RURAL ROADS. ALSO, THE VEHICLE HAS BEGAN HESITATING WHEN ACCELERATING MOSTLY @ 45-50 MPH. THE DEALERSHIP COULD NOT RE-CREATE ISSUES AFTER FIRST INCIDENT AND THE DIAGNOSTICS DID NOT SHOW ANY ERROR CODES. FORD ISSUED TSB'S IN 2008 DESCRIBING " THE ENGINE PROBLEMS ARE THE RESULT OF DEFECTS IN THE FOLLOWING VEHICLE SYSTEMS AND COMPONENTS: ...POWERTRAIN CONTROL MODULE (PCM), ...TRANSMISSION CONTROL MODULE (TCM, ...ELECTRONIC THROTTLE CONTROL (ETC) AND/OR THE THROTTLE BODY ASSEMBLY" WHICH CAN LEAD TO THE FOLLOWING PERFORMANCE AND SAFETY ISSUES " ACCELERATION HESITATION, LOSS OF REVOLUTIONS PER MINUTE, STALLING, LOSS OF POWER (INCL. LOSS OF POWER AT HIGH RATE OF SPEED), SUDDEN AND INTERMITTENT DECELERATION AND OTHER SIMILAR AND POTENTIALLY LIFE THREATENING MALFUNCTIONS." SEVERAL COMPLAINTS HAVE BEEN MADE DIRECTLY TO NHTSA. IT IS IRRESPONSIBLE THAT THE OEM IS ALLOWED TO CONTINUE WITH THIS PRACTICE IN THE NAME OF PROFIT AND IS NOT REQUIRED RECTIFY THE DEFECTS IMMEDIATELY AND CONTINUES PLACING CUSTOMERS IN DANGER. THE RECENT GM CASE SHOULD HAVE TAUGHT US ALL A LESSON.
