First issues is the high pressure fuel pump the cp4. They tend to fall apart sending metal through your injectors all the way back to the fuel tank. It is a well known issue and dodge has made the recall on the same pump. Second is the shaking of the steering wheel after hitting a bump in the road you have to slow down below 25 mph to get it to stop it’s know as “ death wobble”. The other issue is the upper oil pan leaks had it repaired under warranty and less than 2 years later it is leaking again. It is also a well known issue with the 6.7 power stroke diesel motor.

While drivingmy ford f350 crew cab longbed diesel 4x4 at 70 MPH on interstate 10, a 4 lane hwy in each direction, the truck lost all engine power and power assist to the brakes and power steering. Luckily the traffic was light and I was able to maneuver the off the hwy without coming in contact with another vehicle. The truck was towed to a ford dealership and it was determined that the high pressure fuel pump came apart and put metal shaving everywhere throughout the fuel system. Ford recommended replacing all of the high pressure system this included all new fuel injectors. This repair cost $9,000.. A search of the internet revealed that this is a known failure. I had an independent lab test the fuel. There were no contaminants in the fuel except the metal shaving from the pump. ( the ford fuel system recirculates the excess fuel back to the tank) the truck has 115000 miles. I had the ford maintenance agreement with the 5000 mile services option. Ford has provided all of the service including the ones after the maintenance agreement ended. This is a very expensive repair to undertake on a 7 year old vehicle. Engineering changes could have prevented the extent of the damage. A post pump filter or screen would have prevented the rest of the high pressure system from needing replacement. An advisory about the potential pump failure and replacing the pump before failure would have costed less than $2000. Had I been towing near full gcwr, 21,000 lbs and come up on los angeles stop and go traffic, this could have be a terrible accident.

This diesel truck was being driven at 20 MPH when without any warning, the engine shut off resulting in loss of all power steering and brakes. Would not restart. Towed to dealer service. Dealer diagnosed lack of fuel pressure and they observed metal shavings in the lower filter indicating the hpfp was disintegrating. Dealer submitted pictures of the flow control valve to ford warranty prior approval per service manual directions. Dealer observation was that they observed no significant water or debris contamination in the fuel filter. Prior approval response was that the pictures submitted were representative of fuel contamination and denied the warranty coverage for the repair. No water in fuel indication was ever seen by owner. Filters maintained per maintenance schedule. Bill for repair is estimated at approx $11,000. Two weeks prior, this vehicle was towing a 14k lb 5th wheel down the santiam pass in oregon. Steep inclines, sharp drop offs, and snow on the road. A sudden loss of power without warning would very likely have resulted in loss of control of the vehicle, severe bodily injury, or death. It appears the bosch cp4 fuel pump was not designed to operate with the 560 scar fuel lubricity of us fuels and that ford is blaming pump failures on water contamination by observation of a corrosion appearance on another component. Warranty coverage was denied without any observation of the fuel pump itself. Note that no indication that anything was wrong with the truck was observed prior to the failure. The truck is equipped with a factory 5th wheel hitch and is intended to haul up to 21.5k lb trailers. Sudden loss of power steering and brakes without warning under this intended use is extremely dangerous.

According to ford the truck's fuel pump went out. They said it was back ordered. 1100 trucks affected. I don't believe ford is supplying the whole story on the issue and their is a lot more to it. Ford is hiding something and you should look into it. I fortunately was in a safe place when the pump went out but others may not be.
