What owners report
Failed Component & Availability for Inspection: The Bosch CP4 high-pressure fuel pump (HPFP) failed internally, shedding metallic debris throughout the entire fuel system. This matches the exact defect in NHTSA Recall 24V-957 and Ford Safety Recalls 24S78 and 26S17. The failing CP4 pump and eight injectors were replaced on 03/14/2026 (Eastpointe Invoice #5997) due to contamination. The truck is located at Bob Maxey Ford in Detroit, MI, and is available for inspection alongside work orders from an authorized Ford dealership and two independent facilities. Safety Risk: The failure caused an abrupt, total loss of motive power on an active highway off-ramp, followed by an immediate no-start st

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.
The contact owns a 2021 Ford F-350 SD. The contact received notification of NHTSA Campaign Number: 24V957000 (Fuel System, Diesel). The contact stated that while driving 20 MPH, the message "Reduced Power" was displayed, and the check engine warning light was illuminated. The vehicle stalled and failed to restart. The vehicle was towed to a dealer and was diagnosed with failures of the CP4 fuel pump, cycloid filters, and contamination of the entire fuel system. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 30,000.
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.
