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.
