I was making a left hand turn afyer stoping at a traffic light and loss power. The engine light came on and the turbo pressure gauge dropped. I took the truck into the dealer and the dealer told me that a manafold bolt had broken which caused a bad exhuast leak. Repair cost was $3500. I drove the truck less than 50 miles over the next two days and the problem happened again with loss of power and engine light on. I took the truck back the dealer and was informed that the high pressure fuel pump had exploded and sent metal debris through out the fuel system. I was then told the repair cost were going to $7500 ($6000 for parts and $1500 for labor). This is a bad Ford engineering design problem and should be paid for by Ford as well as a recall on all models using the same hpfp assembly.

Vehicle looses power, no acceleration, occurs most frequently under heavy load or high acceleration demand, told by Ford dealer the problem is caused by de-laminating fuel tank resulting in fuel tank coating entering the fuel system and obstructing diesel fuel flow to motor when high demand for duel occurs. Near collision at freeway speeds and was very dangerous to pull over when there was no shoulder. Ford dealer states the cost to repair is over $3,500.00 and open ended depending on whether the fuel tank coating entered the motor or injectors. They want to start by replacing the harness, fuel tank and fuel pump and go from there. Ford refuses to honor this clear manufacturing defect.
