What 1,155 owners told NHTSA about the 2017 Ford F-250 Supercab

On 5/8/2026 at 1555 hours, while driving at normal freeway speed under normal driving conditions, vehicle began an exhaust system regeneration cycle. During the course of the region cycle, vehicle began to smoke excessively and realizing this wan not normal, I was able to yield to the right shoulder of the roadway. Almost immediately the vehicle ignited on fire and completely burned to the ground. The fire appeared to have commenced in the engine compartment, driver side near the firewall. The location of which appears to be consistent with reports of fuel filter failures I have read about in the past. The resulting fire ignited nearby brush which burned several hundred feet of brush and resulted in the spillage of diesel fuel and coolant which combined from the resulting melting of the coolant system and fuel tank and lines. This incident put both me and surrounding communities at risk, particularly from the resulting fire and HAZMAT spill. The vehicle was in good running condition prior to this incident. The incident was investigated by the Templeton California Highway Patrol.

I am reporting a serious safety issue involving my 2017 Ford F-250 diesel truck. While towing a 34-foot fifth wheel trailer and traveling from [XXX] to [XXX] , the vehicle experienced a sudden and dangerous failure near [XXX] . The engine warning light appeared, the vehicle went into low power mode, and then completely shut down on the highway. This created a serious safety hazard, particularly while towing a large trailer at highway speeds. The vehicle was towed to a repair facility where it was determined that the high-pressure fuel pump had catastrophically failed. The pump had developed a significant crack and released metal debris throughout the entire fuel system. This required extensive repairs, including: - Replacement of the high-pressure fuel pump - Replacement of fuel lines - Full fuel system cleaning, including the fuel tank The total repair cost exceeded $14,000 USD (near $20,000 CAD). The mechanic indicated that this type of failure should not occur under normal operating conditions. Additionally, the Ford parts dealer advised that the failed fuel pump could be returned for credit, suggesting the failure may not be consistent with normal wear and tear. This failure occurred suddenly, without warning, and resulted in a complete loss of power while driving, which I believe represents a significant safety concern. I respectfully request that NHTSA investigate this issue as a potential safety-related defect involving high-pressure fuel pumps in diesel vehicles.

This past year I experienced catastrophic failure with my Bosch, CP4 fuel pump in my 2017 Ford F250 with a 6.7 L diesel. Recalls have been published by Ford, but not beyond a 2018 vehicle. After seeing metal fragments in my fuel water separator, I was forced to flush my entire fuel system, replace the CP4 fuel pump with a CDR high pressure pump (replacement), flush the entire fuel rail system and replace my fuel injectors. This repair cost me approximately $13,000. I find it difficult to understand why my 2017 vehicle was not included in the recall when it had the defective item as the later models had. The truck has 129,000 miles on it currently. Certainly, these are not excessive miles given the year of the vehicle. I would like to know what can be done for older models(the Bosch CP4 fuel pump goes all the way back to 2011). Thank you for your consideration and attention to this

2 different issues- 1st issue was Ford factory fuel filter leaked at a seam. Resulting in fuel loss all over engine! 2nd issue is fuel filter inlet line retaining clip comes unclipped on its own resulting in fuel loss all over the engine. Both incidents happened during long distance travel which also resulted in several gallons of fuel drenching whole undercarriage of vehicle.

We get a power reduced code and the truck shuts down while driving. We have to pull over and put it in park and restart it. When we are on the freeway we can’t get over we put it in neutral and turn off the truck and restart it. It is very scary and dangerous! This has been happening since June of 2025.

While pulling a 38ft 5th wheel camper on an incline with the cruise control set at random the vehicle completely dies. It experiences a total shutdown of the engine, which in return causes a complete loss of power steering, brakes etc. The truck will not restart until you push the off button and open the drivers door to shut the entire system down

A message was displayed to reduce the truck speed. Then the speed started to reduce itself, I wasn't able to increase the speed. I was on a Hwy and the speed limit was 65 mph and on a slight hill the trucks speed was only 39 mph. I put the flashers on hoping to alert the cars passing me that I had a problem. Then the engine died so I steered it over to the side of the road. I tried to re-start it and the truck shook before it died again. I had it towed to a Ford dealer in Boerne, TX. They called me the following day and said the high-pressure fuel pump came apart. They said they saw metal parts in the fuel and their estimate to fit the truck was $18,000! I had it towed to another automotive place, I just needed another opinion. Then I heard about 2 recalls Ford had this year, 1 in January and another just ramping up. The description of the problem sounds exactly like my issue however it didn't cover the 2017 models! I let Chandler Automotive, in Castroville, TX know and they said they would look in to it.

Ford has a problem where the 34 gallon gas tank only reads as a 20-25 gallon gas tank. They have a service bulletin on it and the number for that is 17-0046. After calling multiple dealerships I was told thousands would have to come out of my pocket because of their factory defect. The fix includes replacing the whole fuel tank and also replacing the fuel level sender. My vehicle being within the dates are clearly affected by this defect and I don’t understand why it should be coming out of my pocket. Thank you for your help!

Fuel pump loses prime at the fuel rail, causing 6.2 gas engines to crank for a long time. Faulty check valve. It seems ford made a revision on the pump and never did a recall.

I own a 2017 Ford F-250 6.7L Power Stroke Diesel with a CP4 fuel pump that recently failed. Ford has already recalled this exact part for 2020-2022 models (Recall 24V-841) due to known defects, but they refuse to assist owners of earlier models like mine, even though the issue is the same. The CP4 failure can cause sudden fuel system failure, which is dangerous while driving. Ford should extend the recall to cover all affected vehicles before more owners are left with costly repairs or safety risks.

On Tuesday, [XXX], at approximately [XXX] PM, I was driving southbound on [XXX] near Coalinga, CA, when my truck suddenly experienced a failure. I noticed smoke in the side mirror and asked my passenger to confirm. Moments later, a "Low Fuel Pressure" message appeared on the dashboard, and smoke began coming from the hood. I immediately pulled over and attempted to pop the hood, at which point flames erupted from the engine bay. The fire quickly spread, fully engulfing the vehicle within minutes. Emergency responders, including Cal-Fire and CHP, arrived on the scene. The truck was towed by Cal-State Towing Service in Huron, CA. The Fire Captain on site provided an incident card, but the full fire report is expected to take at least a week to obtain. There were no prior indications of mechanical issues before this incident, and no recent repairs or modifications to the fuel system or engine. However, I recently became aware of an ongoing NHTSA investigation into fuel leaks and fire risks in Ford Super Duty trucks equipped with the 6.7L diesel engine (TFL Truck Report). The investigation highlights a potential issue with fractures in the secondary fuel filter housing, which could lead to fuel leaks and fire hazards. Given that my truck displayed a Low Fuel Pressure warning immediately before catching fire, I strongly suspect this failure may be related to the issue under investigation. The truck is currently in tow yard storage and is available for inspection upon request. This incident posed a serious safety risk to myself, my father and others on the roadway, and I believe it warrants further examination by NHTSA.

The CP4 fuel pump began failing with the truck just over 100K miles. When taken in for routine service there were traces of metal shavings in my fuel. This is a widely known problem with the CP4 and is still being used in Ford trucks. The cost of repairs is substantial. The best case is you catch it early and it only costs between $3-6,000. If I had not caught this and the entire fuel system had been damaged, my local Ford dealership informed me it could cost close to $16,000. This is a devastating amount of money to pay for a well known issue in Ford trucks.

The hose connecting to the fuel filter in the engine compartment came off and dump fuel all over the engine. Luckily we turned it off before a fire started. This has happened 3 times now.

I have been made aware of the probe involving 2015-2021 Ford Super Duty pickups where the fuel filter housing and fuel lines have cracked. I wanted to make you aware that in November 2023, my vehicle suffered the same part failure. Park Ford in Tallmadge Ohio did the repair and I paid for it out of pocket. It was significant and I had diesel fluid leaking profusely. My vehicle is a 2017 Ford F-250 with the diesel engine and at that time only had approximately 50,000 miles on it. I thought it was odd that this part failed. I see it may not have been an isolated occurrence. I wanted to add my complaint to those being investigated by your agency.

This is the third time i have had to tow this vehicle in less than a year and half for a Long Crank no start. The fixed a melted wiring harness the first time. Second time couldn't tell me what the problem was but got it running and then now its back at the dealership again for the same problem.

The engine light activated on the dash randomly while driving. My truck was experiencing loss of power and for the next few days and reduced fuel mileage. I checked the engine code and learned it is a common error with 2017 Ford Super Dutys with the 6.7L diesel engine. The code is “DTC P203B”, sometimes indicated as P203B00 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing reductant level sensor circuit range/performance. I believe this error in manufacturing is a safety risk because it is common within these trucks and can leave motorists stranded or potentially disable the vehicle in the roadway causing a traffic hazard.

While responding my personal vehicle to a motor vehicle collision (volunteer first responder) my 2017 f250 lost all power at 70+ miles an hour on a highway. Power steering and power brakes were not functioning and caused a delay in service to the community. Mechanic diagnosed it as a contaminated fuel system from the problematic Bosch CP4 pump, which Ford is well aware of. They even have a “kit” to fix this issue costing well over $6,000. This is a major safety issue when all power is lost especially if towing trailers.
