2018 Ford F-350 SD: fuel pump failure

Filed Oct 15, 2026 · Fuel system · WI

I request that the federal safety agency investigate potential safety risks associated with the Bosch CP4 high-pressure fuel injection pump in the 6.7L Power Stroke diesel engine used in my 2018 Ford F-350 Super Duty. My truck has approximately 148,000 miles. I purchased it used and am concerned about potential catastrophic pump failure, sudden engine power loss, fuel-system contamination, and substantial repair costs. A CP4 pump failure can release metal debris into the fuel system, potentially damaging injectors, fuel rails, lines, and other components and requiring extensive repairs. Sudden engine power loss while driving or towing could create a serious safety hazard, particularly on highways. I understand that certain vehicles from Ford and other manufacturers have been subject to recalls or safety actions involving CP4 high-pressure fuel pumps. I ask the federal safety agency to determine whether those actions involve the same or substantially similar pump design and failure mechanism as the pump installed in my 2018 F-350. Please review available failure data for 2018 Ford F-350 trucks equipped with the 6.7L Power Stroke diesel, evaluate the risks of fuel-system contamination and sudden power loss, and determine whether existing investigations or recalls should be expanded to include this model year or other affected vehicles. I request that the federal safety agency investigate whether this potential defect presents an unreasonable safety risk and require appropriate corrective action if a safety defect is identified. Owners should not have to wait for a potentially dangerous failure and extensive fuel-system damage before this concern receives adequate investigation. Vehicle: 2018 Ford F-350 Super Duty Lariat Engine: 6.7L Power Stroke diesel Approximate mileage: 148,000 miles Pump status: No confirmed pump failure reported. Thank you for reviewing this safety concern.

While pulling from a fuel pump I began turning when I heard a loud noise. The tailgate had inadvertently opened and pierced through the front of a 5th wheel camper I was pulling. This caused significant damage to the camper as well as the to the top of the tailgate. This 1st incident happened ~ 3700 miles. I latched the tailgate and picked up another trailer (pintle hitch). I pulled into a parking lot to drop off the load and noticed that the tailgate had came down a second time. After dropping trailer off I began to drive home. Half way home to get fuel (un laden) I noticed the tailgate down again. The remote nor the dash button had been touched. The tailgate has since been removed as I can not risk further damage caused from my tailgate opening by itself. I informed my dealership (ryan ford of sealy,tx.) multiple times of the incident however was replied with only that there was no active tsb issues for my VIN.
