FUEL/PROPULSION SYSTEM
Vehicle lost complete power unexpectedly.
NHTSA complaint #11762616 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
The high pressure fuel pump failed sending metal shavings through out the entire fuel system. I had no heads up and the failure left me stranded on top of a bridge. I called 911 twice and finally the cops showed up and wrecker towed me off the bridge. Ford is aware of this known issue with this make and model, and even put a recall partial recall / quick fix to increase the flow around the pump to keep it cooler. I had the quick fix recall completed but it did not prevent the failure and me being stranded on a bridge.

FUEL/PROPULSION SYSTEM
Wife was driving the truck(I was the passenger) while towing our dump trailer. After approx 100 miles into this trip the dash showed a "Reduced Engine Power Warning", and then shuddered. That was immediately followed by a "Service Engine Soon" warning on the dash, and the truck shut down as we were pulling to the shoulder. I smelled diesel fuel as we slowed to a stop. I got out and saw some smoke coming from under the hood. I looked under the truck and saw burning material falling from underneath, I shouted fire, and my wife exited while I retrieved our dog from the back seat. The cab was filling with smoke. Wife called [XXX] while I retrieved a few more small items from back seat. We stepped back and the truck was fully engulfed in flames in a few minutes. Fire crews were on scene after several more minutes, and by that time the truck was burnt to the ground. This truck was in excellent condition with no prior running issues or warnings of mechanical problems. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM
I find it absolutely absurd that the fuel pump recall is still not resolved! When are you going to hold Ford accountable for this egregious delay? This has been over a year now. Everyday I drive my truck and tow my travel trailer wondering if at anytime it may just die on me on the highway.
NHTSA complaint #11757127 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
I have a 2017 ford f350 diesel 6.7 and replaced the low pressure fuel pump in 2022 at about 57000 miles. Then again in July of 2026 the fuel pump has had to be replaced again at 68000 miles. I read that many 2022 ford vehicles were recalled in that year for a bad fuel pump. So I think I might have been given a bad fuel pump from that year 2022 and now its bad again. This is a know problem for fords I dont understand why there is not a recall for these pumps. Ford is been building bad pumps for a long time and are getting away with it, A fuel pump should not have to be replaced after 3 years. The work was all done at the Beach Ford Dealership in myrtle beach sc 29575.
NHTSA complaint #11755600 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
Our 2018 Ford F-350 Super Duty diesel with the 6.7L Power Stroke engine has a well-known, massive fuel system concern involving the Bosch CP4 high-pressure fuel pump. This pump failed and it sheds metal shavings throughout the entire fuel system. Repair cost $13k. Per other consumer and google results: The CP4 Fuel Pump Issue. The Defect: The Bosch CP4 pump is designed for European diesel fuel, which has more lubrication than American diesel. When it lacks sufficient lubrication, it can score itself and self-destruct. The Damage: Metal debris floods the fuel rails, lines, and injectors, requiring a complete replacement of the fuel system components.
NHTSA complaint #11755489 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
Vehicle went into limp mode and we towed it to the dealership. They ran diagnostics and found that the fuel filter was causing a fault for water in the fuel filter. They replaced the fuel filter and ran diagnostics again and it flagged failure for Low pressure fuel pump. They replaced the low pressure fuel pump and reran diagnostics. When they reran diagnostics it flagged for High pressure fuel pump failure and now they are in the process of tearing it down to the point of failure to find out the cause. My vehicles vin was not included in the original recall and believe that it should have been included.

The contact owns a 2020 Ford F-350. The contact stated that while driving 65 MPH and towing a dump trailer, the vehicle entered LIMP Mode. The contact was able to pull over to the side of the road. The vehicle was towed to the contact's storage yard, where an independent diesel mechanic performed a diagnostic scan and retrieved diagnostic trouble codes indicating a fuel system failure. The vehicle was towed to a dealer, where it was disassembled and diagnosed with a CP4 pump failure resulting from a water separator failure. The contact was informed that the CP4 pump replacement was not covered and needed to be replaced at the owner's expense. The manufacturer was notified of the failure and contacted the dealer, but no further assistance or information was available. The vehicle was not repaired. The failure mileage was approximately 180,000.

FUEL/PROPULSION SYSTEM
I am filing this complaint regarding my Ford F-350, VIN [XXX], which caught fire on XXX. The truck had approximately 130,000 miles, which I consider low mileage for a properly maintained diesel Ford F-350. These trucks are known for long service life, and many Ford diesel trucks routinely remain in service for 20 years or more and exceed 250,000 miles when properly maintained. For that reason, I did not expect a sudden and catastrophic fire in a truck with only 130,000 miles. While driving, passing motorists alerted us the truck was on fire. The fire appeared to originate in the engine compartment and spread extremely rapidly. Within a very short period, the front of the truck was engulfed in flames and sustained catastrophic damage. Based on the speed and severity of the fire, I am concerned a failure in the engine compartment, fuel system, electrical system, or another vehicle component may have caused or contributed to the fire. This truck has been well maintained, kept clean, and responsibly cared for. I followed the manufacturer’s maintenance guidelines and did not expect a sudden engine-compartment fire. After the fire, I found reports of other F-350 fires and references to fire-related complaints and investigations. This raises serious concerns Ford may have known of a potential fire risk involving these trucks. This incident created major safety hazard not only to the occupants of the truck, but to other motorists and anyone nearby. Had passing drivers not alerted us, the outcome could have been far worse. The severity of the fire required a major emergency response, including multiple fire trucks and police. A vehicle fire of this magnitude presents an obvious risk of serious injury or death. I request NHTSA investigate Ford F-350 and vehicle fire incidents to determine whether a defect involving the fuel system, electrical system, or related parts may cause these trucks to catch fire without warning.

NHTSA complaint #11749092 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
This model has the same Bosh CP4 high pressure fuel pump as the recalled models 2020-2022 and in fact being older the catastrophic failure risk is higher due to additional mileage. If this part fails the engine shuts off with loss of steering and braking even when pulling 15-20K pounds. The safety concern for this year is the same or greater then newer models.
