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.

What owners say
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 the federal safety agency 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 stall. Coasting without motive power across traffic lanes created an imminent collision hazard before the truck was towed by Troy’s Towing on 06/05/2026 (Invoice #34647). Problem Confirmation: •03/14/2026: Eastpointe replaced the failed CP4 pump and eight injectors (Inv #5997). •04/07/2026: Bill Brown Ford pulled DTC P228F, found debris on the regulator screen, and advised full fuel system replacement (RO #80302). •04/29/2026: Eastpointe confirmed metal contamination upon teardown (Inv #6342). •05/14/2026: Diesel’s Place found metal shavings on the regulator valve (Inv #2118). •Current: Bob Maxey Ford scanned DTC P0087 but reported no debris, contradicting prior documentation. Inspections: Bill Brown Ford inspected the vehicle on 04/07/2026 and documented debris. Bob Maxey Ford retrieved DTC P0087—a qualifying code for full fuel system replacement under Ford Recall 26S17—yet Ford Corporate denied coverage based on their claim of no metal shavings. Warning Signs & Timeline: In March 2026, the Check Engine Light illuminated with severe engine jerking (pump/injectors replaced 03/14). Bill Brown Ford confirmed DTC P228F and screen debris on 04/07. Metal shavings were reconfirmed on 05/14, leading to a highway stall/no-start on 06/05 and a stored DTC P0087 at Bob Maxey.

The contact was informed that the failure codes displayed were not associated with an unrepaired recall. The contact received notification of the federal safety agency Campaign Number: 24V957000 (Fuel System, Diesel). The manufacturer was contacted by phone, and a case was filed. The failure mileage was approximately 89,545.
On 09-25-2026 I was changing the fuel filters on my truck when i noticed metal shavings in the bottom of the fuel filter. Immediatey contacted Norman's Auto & Diesel Repair and i had the truck towed to Norman's. The CP4 fuel pump was failing, they converted to the DCR fuel pump. The truck only has 71,234 miles on it and this problem cost me over 4,000.00 dollars. All Ford 6.7 diesel from 2011 to 2026 should be recalled. This is a problem that Ford has been knowing about since 2011. INVOICE #018016
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 2020 Ford F-350 SD. The contact stated that while attempting to start the vehicle with the ignition key, the vehicle failed to start as intended. The check engine warning light was illuminated. In addition, the contact associated the failure with the federal safety agency Campaign: 24V957000 (Fuel System, Diesel); and the VIN was included. The vehicle was towed to a local dealer where it was diagnosed with the fuel pump failure. The vehicle was not repaired under the federal safety agency Campaign Number: 24V957000(Fuel System, Diesel); because there was no metallic debris found in the fuel system. The manufacturer was made aware of the failure, and the recall repair was denied. The failure mileage was approximately 230,000.
The contact owns a 2021 Ford F-350 SD. The contact received notification of the federal safety agency 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.
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.
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.
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.
