This truck had a complete fuel system replaced already once when it failed while the customer was driving. We are the next owners and didn't know it had this major failure before purchase. We know this fuel pump is an issue and Ford has active law suits against them as these pumps that they continue to put even in the new Fords and all other makes of trucks are blowing up daily. Ford sees it as a revenue stream to keep their shops busy. Fuel is highly flammable and we tow a travel trailer. I would hate to see something bad happen because they won't issue a recall. There several years that are under recall currently and our year is not one of them but it has the same pump. They should not only issue recalls on all trucks that have the known failing CP4 pump, but also give the customers the option to upgrade with the after market DCR pump. The one pump that has been the #1 best replacement option. Installing a new CP4 pump only buys Ford mote time to next failure and keeps their ships full. We spent 50k on this truck. Again, it already happened once! Let's be sure to issue recalls on ALL trucks with CP4 pumps with a real solution and not just another dangerous CP4. We don't want our truck to catch on fire while driving. Its a very big safety concern!

Engine Shuts Off Upon Acceleration on the onramp to a interstate highway causing the Ford f350SD, 6.7L Diesel to come to a stop in the outside lane of Interstate I81. Engine Shutdown happened again on a 2 lane highway while passing a slow farm tractor. The problem has been confirmed by Harrisonburg Ford, Harrisonburg, VA. The high pressure fuel pump is causing metal to be distributed throughout fuel system. The complete contaminated fuel system is required to be replaced by a High Pressure Fuel Pump KIT, which the Dealer ordered against the workorder for my truck. For over a month now, My truck is parked in the dealer storage and stating they are waiting on approval to start repair. Note I have Ford's Extended Warranty. I've read online that many other owners of 6.7L Diesel trucks are having the same problems. I my opinion, a RECALL is certainly justified for this issue.

The Fords have two issues with the fuel system. The CP4 fuel pumps have a common failure imploding and sending metal through the fuel system, a costly repair over $12,000. The second extremely dangerous failure on the fuel filter housing. It cracks spraying fuel into the engine compartment. If not shut off immediately a fire engulfs the car. Both are extremely Common, a safety hazard and expensive repair that Ford should fix immediately.

The owners manual states I have a tank capacity of 36 gallons. On E I can only fit about 26 gallons. If I were to take my average MPG and use the advertised 36 gallons to figure out how far I would run out of fuel and this would cause the vehicle to stall while driving. Ford is aware of this issue and knows how to fix it but declined to take care of the safety repair.

2017 Ford F350 Superduty 6.7L diesel will intermittently surge/buck while towing uphill under load causing loss of power and creating unsafe driving situation. When it happens I’ve also observed electrical power loss to OBD-II port where I have accessory guage installed to monitor critical truck systems like oil temp, trans temp, coolant temp, etc.. No DTC or fault codes are generated when this happens. I haven’t taken to dealer yet but I’ve researched and read lots of truck forums where multiple Ford owners have had the same issue. When they’ve taken their truck to the dealer they’ve been told this is “normal”. I don’t agree and believe this is a serious safety issue to a consumer that suddenly loses all power and must let off all acceleration while other cars are following/around vehicle when vehicle surges. This has now happened four different times and various speeds (30-60 mph).

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.

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.
