Ten problems related to diesel engine have been reported for the 2008 Ford F-250. The most recently reported issues are listed below.
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 numerous occasions my 08 Ford f250 6. 4 has had excessive bluish white smoke from the exhaust while driving and lasts around 20 seconds. Dealer was notified and situation met all criteria outlined in TSB 11-2-2. Cac was replaced. However, vehicle still intermittently has same problem. On one occurrence the smoke was so excessive that a motorcycle traveling behind me almost ran off the road due to visibility. Ford states that this is normal.
Cpsc# i1310184a. 2008 Ford F-250. Consumer stated that he has had numerous problems with the cooling system. Stated the radiator was leaking also. The consumer stated he was loosing a gallon of coolant a week. It was going through the air charge and out the exhaust. At 89,000 miles, he had to pay $ 1947. 00 to replace both the vertical and horizontal egr coolers. Again, dumping a gallon of coolant into the exhaust system a week which caused severe smoking.
While driving engine power failed and loud knocking noise was heard. Upon being serviced, rocker arm was broken and caused the problems. There was no notice of this issue and it affected sudden loss of power/speed. It is noted that while searching the internet it was discovered that this appears to be a common problem with these 6. 4l diesel engines.
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. . . . . . .
The contact owns a 2008 Ford f250 super duty. The vehicle was taken to the dealer for routine maintenance when the contact was advised that the radiator was leaking. There were no recalls for the failure. The manufacturer was contacted but offered no assistance. The vehicle was repaired at the contacts expense. The failure mileage was 87,000.

The contact owns a 2008 Ford F-250. While driving various speeds, the vehicle hesitates when the accelerator pedal is depressed. The failure has been occurring ever since the dealer changed the computer in the internal engine. The contact received a notice stating that it needed to be changed. The dealer stated that the vehicle was fine, although it has been in the repair shop approximately three times for this same issue. The failure is due to the computer module, which has caused the vehicle to have poor fuel mileage. The dealer acknowledges the failure and the contact believes it is a safety issue. The failure mileage was 16,000 and current mileage was 23,000. Updated 8/10/09 updated 08/13/09.
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.
Ever since I purchased a 2008 Ford F-250 super duty pick up truck with the 6. 4 diesel engine it has had a problem with an intermittent problem with the engine. For no reason sometimes when you accelerate the engine will stumble and a cloud of white smoke pours out of the exhaust pipe. The smoke is so severe it will blind anyone behind the truck. This has happened several times. I have had several cases when trying to merge into highway traffic the engine will stumble and loose all available power. This could be a drastic problem if this is not corrected by Ford motor company. I have had the truck to the dealer several time and they say it is normal for the truck to do this because it is part of the emissions. If this is the case then they are allowing a dangerous situation to take place.
The contact owns a 2008 Ford F-250. While driving in reverse at 1 mph, the vehicle went into fast idle mode and suddenly lunged backwards. The contact slammed on the brake pedal in order to stop the vehicle. The dealer stated that the vehicle was designed to do this as a self-cleaning process. The current and failure mileages were 1,000. Updated 02-01-08 updated 02/01/08.
