2021 Ford F-250 SD: fuel pump failure

Filed Sep 26, 2026 · Fuel system · CA

My 2021 Ford F250 super duty pickup truck experienced a catastrophic failure of the Bosch CP4 high pressure fuel pump. This has been confirmed by the dealer's service center. As a result of this part failure, metal shards were introduced into the entire fuel system. This now requires the fuel pump and the entire fuel system (every component) to be replaced. My truck has 74,9xx miles. This is a known and well publicized issue. Rather than recall the high pressure fuel pump, Ford instead issued a recall (24S78) to reflash the PCM software with the intent to reduce the risk of the fuel pump failure. I had the 24S78 recall work completed, and my fuel pump failed still. No indication in advance of this failure.

This vehicle is subject to two open safety recalls for which no repair remedy is currently available from the manufacturer: 1. Recall 24V957 (24S78) Dec 20, 2024 involves the high-pressure fuel pump and powertrain control system. The recall states the fuel pump may fail and cause extended cranking/no start or loss of motive power while driving. Loss of motive power while in traffic or while towing increases the risk of a crash. The manufacturer has stated that parts and/or software are not available to repair this defect. The vehicle is regularly used for towing a recreational trailer, which increases the safety risk if loss of power occurs during operation, especially at highway speeds or while merging. 2. Recall 25V686 (25SA8) Oct 10, 2025 involves the 360-degree/rear-view camera system. The recall states that the rear camera image may become dark in certain reversing situations when front and side cameras are exposed to significantly more light than the rear camera. Reduced visibility while reversing increases crash risk, particularly when maneuvering a large pickup truck. The manufacturer has acknowledged both recalls but has not provided a repair remedy within a reasonable timeframe. The powertrain-related recall has remained unresolved for an extended period. The vehicle has not been repaired because the manufacturer states parts/software are unavailable. At this time, the defect conditions have not resulted in a confirmed failure event, but the vehicle continues to be operated with open safety recalls that cannot be remedied. The safety risk remains present due to lack of available repair. Due to the prolonged unavailability of a repair remedy for a recall involving potential loss of motive power, I am unable to safely use the vehicle for its intended purpose of towing, as doing so would increase the risk of a crash if the defect occurs.

The vehicle experienced a sudden loss of motive power and became inoperable due to failure of the high-pressure fuel system. This VIN is subject to an active safety recall (the federal safety agency 24V957 / Ford 24S78) addressing high-pressure fuel pump failure that can result in loss of motive power while driving. Prior to failure, the vehicle exhibited reduced engine performance and drivability issues consistent with fuel system malfunction. No Water-In-Fuel warning or alert was displayed prior to the failure. The vehicle was inspected by an authorized Ford dealership. Ford and the dealership asserted “fuel contamination” as the cause and refused to repair the vehicle under the recall or warranty unless the customer paid for diagnostic teardown. The recall repair was not performed. The vehicle remains unrepaired and was removed from the dealership. The loss of motive power created a safety risk to the occupants and other motorists. We are concerned that a recalled safety defect affecting the fuel system is not being remedied and is being mischaracterized to avoid recall repair.

ON YOUR VEHICLE, IT MAY BE POSSIBLE FOR AGED BIODIESEL DEPOSITS TO ACCUMULATE IN THE HIGH PRESSURE FUEL PUMP.

We took it to the manufacturer, and they said it was because of the recall. The recall date is Dec 20,2024 and it is now June 24, 2025. That is 6 months without a remedy. This is not being taken care of in a timely manner.

We were on the interstate and our truck had reduced power and then failed. The diesel particulate filter light came on as well as the service engine soon warning. We were hauling our 40 foot 5th on the way home from a trip. We were able to make it to the side of the road but it would not start. It would crank for a while then quit. We were stuck on a very busy/dangerous highway for over 2 hours waiting on a tow truck to get us. It cost $500 to be towed to the ford dealership 2 miles away. We were nearly 3 hours from home. Our truck and 5th wheel are both still at the dealership. We were told today that the fuel pump exploded leading to shards of metal throughout the system and that it would be $15000-18000 to repair. There isn’t a solution with the recall but it will be covered under our powertrain warranty. We are left without a truck and have no way to get our camper home until it’s repaired.
