2008 Ford F-250 SD: sudden loss of power

Filed Apr 8, 2015 · Electrical, Engine · 80,121 miles · CA

We purchased this 2008 ford f-250 super duty new at the ford store in san leandro, ca on july 21, 2007 and continue to be the original owners. This vehicle is equipped with a 6.4 turbo-diesel engine. This vehicle is subject to tsb 07-26-2 (wiring harness defect on hpfp) issued august 2007. On the morning of march 27, 2015, while accelerating onto a freeway and at an approximate speed of 50 MPH, the engine shut down without any warning. I lost all acceleration and the engine died. Braking and steering were also diminished. I got lucky and was able to avoid a collision and coast to the side of the road where the vehicle would not restart. The vehicle was towed to a local repair shop (bud adams - castro valley, ca; bar#:228593 cal#:66801). Diagnosis revealed a short in the wiring of the high pressure fuel pump gasket wiring harness (the subject of tsb 07-26-2 wherein ford recognized on or about august of 2007 a problem with unprotected wiring within the hpfp wiring harness). Repairs were extremely costly ($3,791.89 reduced to $2,591.89) but more importantly this instantaneous failure without warning is going to cause an accident, injury or death; it is only a matter of time. I got lucky. I see other complainants who had hours stuck in the desert, someone with a load of cattle stuck without warning, the list goes on. In each reported instance the operator described an immediate loss of power plant with no warning. I urge the ntsb to investigate these unplanned shut downs of this vehicle's power plant. Under certain circumstances this may lead to loss of control of the vehicle, collision, injury and possibly death. Ford has known about this issue since august of 2007 yet has not issued a recall. Some may say this is due to the large costs involved to remove and replace the hpfp gasket and wiring harness (in part involving the removal of the vehicle's cab).

On 2 oct 2008, radiator was discovered to be cracked and leaking at left lower corner at 6,240 miles and was replaced by ford under 3yr/36000 warranty. Ford installed degas bottle "t" fitting to eliminate any further radiator failure. On 12 mar 2012, radiator was discovered to be cracked and leaking from left lower corner at 47,895 miles. Ford said failure was caused due to an hyper-extended thermostat. Ford replaced thermostat under warranty but would not cover radiator under warranty. Radiator was replaced by non-ford mechanic. On 25 apr 2013 radiator was discovered to be cracked and leaking from right side seam at 58,520 miles. Ford was contacted and offered no help outside of warranty. Radiator was replaced by non-ford mechanic outside of warranty. It doesn't take a rocket scientist to know there is something seriously wrong with the 08 f250 6.4 cooling systems that ford fails to take responsibility for. I tow a 35ft 5th wheel several times a year and my biggest fear is the radiator going out while towing. If the radiator blew and the truck went into "reduced power" mode, there is a great possibility that a life threatening incident could occur, especially while towing on a step incline. I hope ford figures this out soon before someone gets hurt.

Lifters and cam have failed. And has trashed the motor. Have asked for help from ford and they have denied claim. The problem with this is that $55,000.00 truck that is advertised to be super duty and should last 400000 to 500000 miles with only miner engine repairs, this should not be happening. Ford knows for a fact that they have a faulty motor and faulty internal parts on all the 2008 thru 2010 6.4 l diesel motors. That's why they designed a new motor and are suing navistar the engine designer. Now you can go all over the internet and find thousands of customers with the same problems and more. Ford knows that the lifters will fail at some premature point, and the rocker arms will break. One of the problems is that there is so much back pressure on the motor due too the particulate filter. That has even been re-deigned in there new 6.7 motor. Why is there not a recall on this motor or some kind of mandatory retrofit or financial aid to fix these problems. On another note I have all most had a least 8 head on collisions from lost power due to the egr coolers failing or the particulate filter clogging up. This is a common problem with this engine also you can be in great danger when trying to pass someone. I hope to hear from some one soon.. Thank you in this matter. How can ford turn their backs on loyal americans.......

We where hauling cattle down the highway and lost power at 2500 rpms this was extremely dangerous to be on a highway going 55 MPH with a load of cattle and with no warning the truck lost power. We took the truck into the ford dealership and are now having the high pressure fuel injector pump replaced. The cab of the truck has to be taken off to work on this pump it will be at least 18 hours of labor. Ford has redesigned the newer motors so that the high pressure fuel injector pump is now in the front of the motor. I really think this should be a recall before more people have this happen to them please look into this...

Tl* the contact owns a 2008 ford f250 super duty. The contact stated that the vehicle would lose power while driving up an incline or sporadically at any speed.

I have had many engine problems with my 6.4 diesel from loss of engine power , to lack of power , white /grayish smoke, hesitation , engine almost dying to acceleration and almost causing an accident, I even had an occasional engine light come on, gurgling sounds , whooping sounds and grinding ,metallic sounds coming from my engine. I was told by multiple dealerships that if there is no engine light there is no code if there is no code there is no problem. I was told that my truck was probably going through it's regen process and that the truck will perform poorly when this happens. I now have 9000 miles on my truck this started around 1000 miles and I'm still having issues. I have contacted a lawyer and I'm very disappointed with my vehicle and the dealerships , along with ford motor company who now know I have this problem.
