In November, I accidentally put DEF fluid in the fuel. I took the truck to a dealer for repairs. The check engine light had been on before. They drained the fuel system and replaced filters and such. The check engine light was out. There was no mention of any concerns of any further problems. In February I was driving with a trailer in tow and the truck just turned off in the road. I was not even able to get out of the roadway. At the time the engine shut off a warning light came on to tell me there was reduced engine power. I had the truck towed to another dealer near where I was. They ran diagnostics and changed the fuel filters. No mention of the chance of any continuing problems. The truck shut off in the road again on the way home. I took it to a mechanic near my home. He ran more diagnostics and replaced the fuel rail and other components in the fuel system. Again, no mention of any continuing problems. In April, when I was pulling a trailer again it shut off in the highway again. I had it towed to the mechanic near my house again. He did more diagnostics and said the high pressure fuel pump had gone out and had damaged the injectors. I don't yet have the truck back to see if it will actually run now.

On March 17th, 2023, my 2017 Ford F-350 and I experienced a catastrophic failure of the CP4 high-pressure fuel pump. According to a TriStar Ford (Kittanning, Pennsylvania) diesel mechanic, the CP4 pump literally exploded (mechanically blew apart). At the point of failure on the road, the result was diesel fuel EVERYWHERE on Rt. 422 about 15 miles SE of Kittanning, in the pouring rain. The vehicle stopped on the uphill side of a very steep long slope. The entire engine compartment was flooded with diesel fuel, and the roadway had diesel fuel pooled under the truck, and later, down the storm-water management ditch for several hundred feet. Yes, the diesel-fuel contaminated area was greater than 1600 square feet. CP4 pumps fail all of the time, and Ford knows this. So do YOU! These kinds of failures are SAFETY ISSUES (EXTREME fire hazard!!), and you and Ford have known this for YEARS! You need to make Ford recall ALL vehicles with this CP4 pump installed!

We were driving and noticed a few white puffs of smoke. The next thing that happened was a loud bang from the engine and the cab of the truck filled with black smoke. Within 5 minutes, the entire truck was engulfed in flames, as well as our camper. There was no warning indication on the dash. The insurance company had investigators look at the remains. However, since the truck was aluminum and the fuel filter housing and low pressure side of the fuel system was plastic, everything totally melted. The truck was properly serviced prior to our travels.

On Aug 25, 2021, my son took the truck to Crestview Ford in Crestview, FL with 32k miles on it. The Fuel filter on the engine was spraying diesel from a crack in the housing - Have a video and service records available for review. Crestview Ford replaced the fuel filter housing. On Oct 22, 2021, He was traveling to the Stark Fl area with a 4-wheeler in the back of the truck. He started smelling diesel really bad and pulled over and when he stepped out the steps were covered in diesel. When he pulled the hood release the engine compartment flamed up and filled the cab with smoke. He stepped away and called 911. The truck burned to the ground. I have pictures and fire department report available for review (see attached file). The truck had approximately 44k miles. My research has shown that this is a common problem in 2017 + super duty Ford diesel trucks.

While driving vehicle down the road, "reduced engine power" light illuminates and then the vehicle stalls in less than five seconds. There is no warning of an issue or any problem before the engine dies. This is the second occurrence of this on the truck. It has happened while towing a heavy load. Total loss of power, sterring and braking ability is a serious issue and a danger to the public as well as myself and my family. This issue needs to be resolved by Ford ASAP!

I was driving approximately 70 mph when I crossed a set of rail road tracks and the vehicle shook violently enough to cause me to enter left ditch. After applying the breaks and slowing to 15 mph I regained control. I got out and check the tires and all seemed fine. Started to slowly drive and it was fine. A few miles later I began to smell diesel fuel. When I reached my destination the smell was very strong. Opened the hood and there was fuel leaking from the top of the engine and steaming from the inter cooler. Drive it to a Ford dealer and they replaced the fuel filter as the shaking had caused it to crack.

Vehicle was in motion on a city street and the fuel injector dash light appeared momentarily and then disappeared. Shortly afterwards, I began to sense the slight smell of diesel and just as I turned into my homes driveway there was a loud burst from the engine compartment and the truck began to smoke. I stopped and shut off the vehicle immediately and exited as I was going to inspect the situation. There were screams of fire coming from my wife as the trucks engine compartment began to roar with flames. Action was taken to put out the fire but the flames were too strong. 911 was called and the fire department began in route to our location. In my attempts to contain the fire the truck began to attempt to start on its own. After approximately 3 attempts of the truck starting, there was another loud burst and more flames. Afterwards the horn began to alarm for several minutes. With the help of my neighbors between the water hose and fire extinguisher we were able to contain upon the 18 minute arrival time of the fire department. It is unknown at this time to what caused this fire. Please understand my frustrations as I tell you my 2 year old son was strapped in his car seat in a vehicle that was on fire which was only purchased only 6 months ago from a certified Ford dealership. Photos of engine compartment and cab dash area are attached. Consumer stated he has yet to hear from Ford.

I'm a mechanic at an independent shop. These pickups all have the same problem. Somewhere between 11 and 13 locally. The little fuel line off the top of the filter breaks and fuel everywhere. The last one I had to farmer fix only had 1200 miles on it. Ford needs to fix this problem. All I can do is patch it so they can get home. This is a problem and needs to be looked into. I don't know any other way to do this. When every one of them all have the exact same problem in the exact same spot though?
