The contact owns a 2012 Ford F-250. The contact stated while driving 20 MPH, the vehicle began to make an abnormal cranking sound with several unknown warning lights flashing on the instrument panel. Due to the failure, the vehicle was towed to a dealer where it was discovered that piston rod #3 had snapped inside the engine and that the engine needed to be replaced. After a year, the engine was replaced; however, three weeks later, the check engine warning light illuminated. The vehicle was taken back to the dealer where the contact was informed that the exhaust gas cooling system had failed and needed to be replaced. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline. The vehicle had yet to be repaired. The failure mileage was approximately 42,500.

Ford previously issued warranty extension for this vehicle 18-M-01 related to the replacement of the reductant heater unit. I acquired the subject vehicle above and had the repair done at my expense on September 9, 2015 with 115,710 miles on the vehicle using an OEM part. Eventually, Ford would reimburse me for this expense. The truck currently has 150,000 miles and once again the DEF heater failed . So, roughly 35,000 miles on a single unit. That seems ridiculous to me that an emissions part would fail after a mere 35,000 miles. My experience is far from being alone and others have reported similar experiences on internet forums. I will preserve this unit that failed for 60 days after the submission of this claim in case Ford or you would like to inspect it. Unfortunately, the result of having to perform repeated repairs is that people decide to remove and bypass the DEF system completely. That seems to be a terrible outcome for the environment. However, in communities where there is no emissions testing, no one will find out. Please require Ford to extend the warranty on this part again.

Very intermittently, when I brake this vehicle to bring it to a stop, the engine will start to rev uncontrollably. I have to practically "stand" on the brake to keep it from charging forward. I have to turn off the truck to stop this high speed revving. After this happened 3 times in 2 months we took it to the dealer to check. There was nothing on the floor that could cause the gas pedal to accelerate. The dealer in Kingwood, WV could not duplicate, and found nothing wrong when inspected. We only use the truck once or twice a month so it is a low use vehicle. For this reason the problem does not occur frequently enough to replicate "on demand". While there was not a crash, it almost revved through an intersection and almost ran into another vehicle. Fortunately I was able to throw it into park (Not Good for the vehicle) and then turn it off.

Many early model vehicles with the 6.7 Powerstroke experience broken exhaust manifold bolts. Ford corrected this problem after the first few years of known defects but never issued a recall for the faulty design on 2011-2012 models. The exhaust leak can lead to a lack of power, “limp mode”, and/or a fire as the exhaust is located on top of the engine (not a common design). While Ford is aware of the problem, they’ve done nothing to rectify the situation.

DRIVING TRUCK IT TOLD ME TO PULL OVER AND SHUT ENGINE OFF. I WAS STRANDED ON THE SIDE OF THE ROAD AND IT WOULD NOT RESTART, HAD TO GET A TOW HOME. I DID SOME RESEARCH AND FOUND THIS IS EXACTLY WHAT MY TRUCK DID AS FOLLOWS. WHEN THE EGT SENSOR GOES ON THE BLINK, THE POWERTRAIN CONTROL MODULE THINKS THERE IS AN EXHAUST SYSTEM OVERHEATING SITUATION. THE VEHICLE THEN GOES INTO A 'CONTROLLED POWER REDUCTION MODE' WHILE FIVE WARNING CHIMES ARE RINGING AWAY. THIS ENDS WITH THE ENGINE SHUTTING DOWN COMPLETELY AS SOON AS THE TRUCK SLOWS TO FOUR MPH, WITH NO ENGINE RESTART IMMEDIATELY AVAILABLE.

I HAVE A 2012 FORD F-250 6.7 LITER DIESEL, THE TRUCK HAS 63,000 MILES ON IT AND IS UNDER EXTENDED WARRANTY THROUGH FORD, ABOUT 2 WEEKS AGO TRUCK ENGINE SUDDENLY DIED, LUCKILY WE WERE NOT TRAVELING AT A HIGH RATE OF SPEED. I HAD TRUCK TOWED TO FORD DEALERSHIP AND THEY DIAGNOSED IT AS CONTAMINATED FUEL, WHICH RESULTED IN COMPLETE FAILURE OF FUEL SYSTEM. COST FOR THIS REPAIR IS $10,500 AND FORD EXTENDED WARRANTY DOESN'T COVER BAD FUEL. PROBLEM IS I ONLY GET MY FUEL FROM ONE STATION AND THEY TESTED NEGATIVE FOR CONTAMINATION. MY FEELINGS ABOUT THIS IS THERE WAS NO CONTAMINATED FUEL, BUT INSTEAD A FAULTY COMPONENT IN MY FUEL SYSTEM. MEANING FORD SHOULD BACK UP THERE PRODUCT. AT THIS TIME THE PROBLEM IS BEING INVESTIGATED BUT FORD IS ALREADY SAYING I NEED TO GO THROUGH MY INSURANCE

RADIATOR LEAK FROM DRIVERS SIDE LOWER PORTION. SAME AS PREVIOUS MODEL YEAR ISSUES. FORD CURRENTLY WARRANTIES EARLIER PRODUCTION, BUT WILL NOT EXTEND TO 2011 AND UP. TRUCK HAS ONLY 56000 MILES ON IT. LEAK OCCURS AFTER VEHICLE HAS REACHED OPERATING TEMPERATURE AND IS PARKED AND/OR TURNED OFF. INSPECTION CONDUCTED BY FORD DISCOVERED TANK CRIMPING HAS FAILED AND TRUCK NEEDS A NEW RADIATOR. I AM NOT THE ONLY ONE WITH THIS ISSUE, BUT STILL NOTHING IS BEING DONE TO CORRECT IT.

ON THE FIRST DAY OF AN EXTENDED TRIP WITH OUR TRUCK AND RV, WE ARRIVED AT CAMP TO DISCOVER A MAJOR COOLANT LEAK. THE TRUCK DID NOT GIVE US ANY WARNING MESSAGES THAT ANYTHING WAS WRONG. WE HAD THE TRUCK TOWED TO THE CLOSEST FORD DEALER. THANK GOODNESS THIS PROBLEM HAPPENED IN CAMP, RATHER THAN ON AN ISOLATED ROAD WHERE WE COULD HAVE BEEN 100+ MILES AWAY FROM ANY SORT OF SERVICE. IT TURNED OUT THAT BOTH THE WATER PUMP AND RADIATOR HAD FAILED, WITH UNDER 29,000 MILES ON THE TRUCK. THE WATER PUMP WAS COVERED UNDER WARRANTY, BUT THE RADIATOR WAS NOT. THE FORD SERVICE MANAGER ADVISED US THAT THEY HAD ALREADY REPLACED SEVERAL RADIATORS THIS YEAR, WITH LEAKS IN THE SAME PLACE (DRIVER'S SIDE LOWER CORNER). WE ALSO DID SOME CHECKING ON THE INTERNET AND LEARNED THAT THIS FAILURE SEEMS FAIRLY COMMON. THE RADIATOR SHOULD NOT HAVE FAILED IN SUCH A SHORT AMOUNT OF TIME, WITH LIMITED MILES ON OUR TRUCK.

I HAVE EXPERIENCED TWICE NOW WITH MY 2012 F-250 SUPER DUTY WITH THE 6.7 DIESEL ENGINE. ON FRIDAY JANUARY 22ND AND WAS SIMILAR TO A PREVIOUS EVENT INVOLVING A SUDDEN AND UNEXPECTED ACCELERATION OF MY TRUCK WHILE IN DRIVE. BOTH INSTANCES HAVE OCCURRED FROM THE TRUCK BEING IN A PARKED POSITION WITH THE ENGINE OFF. UPON STARTING THE TRUCK AND SHIFTING INTO DRIVE, I BEGIN TO PULL FORWARD APPROXIMATELY 20 TO 40 FEET AND PREPARE TO STOP PRIOR TO ENTERING TRAFFIC OR REPOSITIONING. THE TRUCK WILL SUDDENLY ACCELERATE AND LUNGE FORWARD. FORTUNATELY IN BOTH INSTANCES MY RIGHT FOOT IS LIGHTLY ON THE BREAK PREPARING TO STOP WHEN THIS HAPPENS. I IMMEDIATELY DEPRESS THE BRAKE WITH A CONSTANT AND HARD PRESSURE AS THE TRUCK'S RPM IS IN THE 2500 TO 3000 RANGE AND I CAN FEEL THE TRUCK WANTING TO SURGE FORWARD. THE FIRST TIME THIS OCCURRED I HAPPENED TO BE PULLING UP BEHIND MY SON WHO WAS IN HIS VEHICLE AND VERY NEARLY MISSED CRASHING INTO HIM. I HAD TO IMMEDIATELY SHIFT INTO NEUTRAL AND SHUT THE TRUCK OFF. ON THE SECOND OCCASION I WAS REPOSITIONING AROUND A VEHICLE WHEN AGAIN THE TRUCK UNEXPECTEDLY ACCELERATED AND I CAME WITH 6 TO 8 FEET OF IMPACTING A CONCRETE LIGHT POST BASE. UPON SHIFTING INTO NEUTRAL THE TRUCK REVVED UP TO APPROXIMATELY 3500 TO 4000 RPM AND AGAIN I SHUT THE TRUCK OFF. AFTER BOTH INSTANCES THE TRUCK WAS RESTARTED AND APPEARED TO DRIVE NORMALLY. IN BOTH CASES THE SERVICE CENTER WAS UNABLE TO IDENTIFY THE CAUSE AND RELATED THAT THEY DID NOT FIND ANY 'ERROR CODES' OR OTHER ELECTRONIC RECORDED EVENTS RELATING TO WHAT I HAVE EXPERIENCED AND AGAIN THE PCM WAS REPROGRAMMED. THE TRUCK IS STILL UNDER WARRANTY AND CURRENTLY HAS ONLY 20064 MILES ON IT.

THE VEHICLE'S ENGINE WILL STALL (CUT OFF) WITHOUT ANY INDICATION OR NOTICE DURING MOTION OR AT A STOP. THIS HAS HAPPENED AT CITY SPEEDS (LESS THAN 25 MPH) AND AT HIGHWAY SPEEDS (GREATER THAN 55 MPH) THE VEHICLE WILL NOT IMMEDIATELY START BUT MAY START AFTER STANDING FOR SOME TIME. THIS CAUSES POWER STEERING, POWER BRAKES AND OTHER IMPORTANT SAFETY FEATURES TO BE DEGRADED OR LOST.
