Diesel Engine problems of the 2012 Ford F-250

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.

Traveling down the highway at 55mph with cruise set and hit brake to turn corner. Engine immediately died with subsequent loss of power brakes and steering--scary because it happened at a critical time while turning a corner on a highway. Absolutely no warning--engine seemed fine prior. Truck would not start. Towed the dead truck to nearest Ford dealer in wellington, KS. High pressure fuel pump failure was the diagnosis. Evidently when this happens, metal filings from the shredded pump take out all the injectors, fuel rail, pressure regulator, and also sends metal filings into the fuel tank via the return line. Ford corporate, not the dealer mind you, claims this failure is a result of fuel contamination in spite of the fact that there are 2 fuel filters and a water separator in the system and they were well maintained. Repairs are estimated at $8000 + and Ford has refused warranty saying it is not their fault. The "fuel contamination" claim by Ford may not even be accurate as their "diagnosis" was made from a picture of the failed part. No fuel tests by Ford were conducted although I did retain a sample of the fuel. No specifics were given by Ford as to what type of contamination either--they just state "contamination". I have no idea if they are talking fluid or solids. Just whose fault is it when the fuel filtering system designed by Ford fails to filter out contaminants? they are denying warranties to thousands of consumers like me, plus they put me in danger with a known issue they fail to take responsibility for--and my government is letting them get by with it. To my knowledge they are continuing to build these 6. 7l diesel engines (it is now August of 2015 as I write this) with the same high pressure fuel pump failures staring the next consumer in the face and pocketbook. Shame on Ford--and shame on the rest of us for letting them get by with it. . .

This is a diesel engine f250. Egt sensor failed and engine immediately shut down in the middle of the road. Cel was on and message said " stop safely now". The failure of the egt sensor was known by dealer and he showed me 2 TSB s on the problem. Problem was fixed in 2 days but the safety aspect of this failure has not been addressed by Ford. A almost immediate shutdown of the engine without warning is very dangerous. In out case we were in town on a side steet but what if this had occurred on the interstate or going up or down on a mountain road or towing a trailer, etc. . We do all this and now that we know we have a over protective computer waiting to kill the engine at its whim we feel much less secure. The computer should give adequate warning before a shutdown and probably should include a limp home option.

After driving for 5 monutes a warning light came on for the rear locking differential- no change in the drivability. About 5 minutes after that the computer started flashing different symbols indicating many problems- the alarms were going off non-stop- then the engine was shut down by the computer. This truck is heavy and I may have caused an accident when it happened because I had to use all my strength to keep it on the road and went into the other lane! if this happened while towing a load on one of the mountain passes I could have been seriously injured or killed- and hurt or killed others! Ford has had bad diesel engines since they dropped the 7. 3 years ago and are ripping off people in this country- please don't let someone die over a known problem. Seems cheaper for Ford to put us in danger by shutting down this engine and therefore not replacing the engine and computer system.

The contact owns a 2012 Ford F-250 sd. The contact stated that while driving 70 mph, the vehicle stalled and an alert advising to stop the vehicle immediately illuminated on the instrument panel. The vehicle was towed to a dealer for diagnosis and the contact was informed that the egt sensor would need to be replaced. The vehicle was repaired. The failure recurred within 8,000 miles. The vehicle was towed and repaired a second time. The manufacturer was notified of the failure. The failure mileage was 48,000 and the current mileage was 56,600.
