Service bulletin SSM 54138

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2024-2025 F-150, Expedition/Navigator, Escape/Corsair, Bronco, Explorer, Mustang, Maverick vehicles equipped with a 1.5/2.0/2.3/3.5L EcoBoost engine and built on 01-Oct-2024 and through 31-May-2025 may exhibit an extended crank condition, strong fuel smell in the engine oil, high engine oil level and may have various drivability diagnostic trouble codes (DTCs) stored in the powertrain control module (PCM) with an illuminated malfunction indicator lamp (MIL). This may be due to an internal fuel leak of the fuel injection pump causing fuel to enter the crankcase and reduce fuel pressure in the high pressure fuel rail. Diagnose this condition using Pinpoint Test HP located in the Workshop Manual, Section 303-04A. If no DTCs are stored in the PCM, proceed from Step HP1 to Step HP5 and continue testing. For claiming, if fuel injection pump replacement is required, use causal part number 9D376 and labor operation code 9543A. If the root cause is identified as anything other than the fuel injection pump, claim the repair outside of this article. Note: Components damaged as a result of this failure mode

Other bulletins for the same vehicles and component
SSM 552112026-10-06. Over-the-air update. 2023-2026 Escape and 2025-2026 Bronco Sport vehicles equipped with a 1.5L EcoBoost engine may require removal of the turbocharger wastegate control actuator linkage for various reasons. The Workshop Manual (WSM), Section 303-04 Fuel Charging and Controls - Turbocharger - 1.5L EcoBoost > Removal and Installation > Wastegate Control Actuator Linkage service procedure has been added. In addition, the wastegate control actuator linkage rod with retaining clips (6K682) and actuator linkage rubber boot seal (9E416) have been released as lower-level components to complete the repair without replacing the entire turbocharger wastegate control actuator assembly.
TSB 26-24282026-10-02. Service bulletin. This bulletin supersedes 25-2326. Reason for update: update the service procedure to include the fuel tank isolation valve replacement, update the causal part number, and increase the labor time allowance to include the fuel tank isolation valve replacement. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P2450 stored in the powertrain control module (PCM). This may be due to the software in the PCM and/or the fuel tank isolation valve.

Reason for update: update the service procedure to include the fuel tank isolation valve replacement, update the causal part number, and increase the labor time allowance to include the fuel tank isolation valve replacement. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P2450 stored in the powertrain control module (PCM). This may be due to the software in the PCM and/or the fuel tank isolation valve.
SSM 551772026-09-21. Service bulletin. Some 2025-2026 Maverick and 2026 Bronco Sport vehicles equipped with an 8-inch instrument panel cluster (IPC) display may exhibit a condition where the fuel gauge displays one mark below the full fuel level when the fuel tank is full. This may be due to the software in the IPC. To correct the condition, download and run the "IPC - Instrument Panel Cluster (IPC) Software Update" application using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 10849 and labor operations 12651D and IPC.
SSM 551402026-09-02. Service bulletin. Some 2025-2026 Maverick vehicles built on or before 05-Dec-2025 and 2024-2026 Nautilus vehicles built on or before 04-Sep-2025 may exhibit limited power and display "Stop Safely Now" or "Service Vehicle Soon" stored in the message center after start up with diagnostic trouble codes (DTC) P0A5D, P0A60, P0A63, P0A6F, P0A72, P0A75, and/or P0E52 stored in the inverter system controller (SOBDMC). The Ford Diagnostic and Repair System (FDRS) may refer to this module as the "Secondary On-Board Control Module C". If the vehicle exhibits these conditions, replace the inverter system controller. Refer to Workshop Manual, Section 307-01B. For claiming, use causal part 7B012 and labor operations 12651D and 12651D56. NOTE: This article does not remove any RVC, Prior Approval or Warranty and Policy requirements for component replacement.
SSM 551112026-09-01. Service bulletin. Some 2022-2026 F-150 Lightning vehicles may exhibit a reduced distance to empty (DTE) projection, a high voltage battery pack state of charge (SOC) that drops from 100% to less than 90% within 60 seconds of being driven, and an inability to reach a target SOC using the scheduled charging feature without any diagnostic trouble codes (DTCs) in the battery energy control module (BECM). This may be due to an issue in one or more cells within the high voltage battery pack. To correct the condition, run the "BECM Battery Health" application using the latest software version of the Ford Diagnosis and Repair System (FDRS). If any cells are identified as exceeding state of charge and/or capacity thresholds, refer to the Workshop Manual (WSM), Section 414-03A High Voltage Battery, Mounting and Cables > Diagnosis and Testing > High Voltage Battery, Mounting and Cables Electric. Perform Pinpoint Test High Voltage Battery Pack Cell Balancing Faults, Step 4 (PPT Step AO4 for 2022-2024 vehicles/PPT Step AQ4 for 2024-2026 vehicles) and proceed with Pinpoint Test directions following the results of Step 4.
TSB 26-23602026-08-10. Service bulletin. Some of the vehicles listed in the Model Statement above may exhibit an intermittent extended crank with no relevant diagnostic trouble codes (DTCs) present. This may be due to various software parameters in the powertrain control module (PCM).
SSM550592026-08-03. Service bulletin. Some 2021-2023 F-150 vehicles equipped with a 3.5L PowerBoost engine, 2020-2026 Explorer vehicles equipped with a 3.3L hybrid engine, and 2020-2023 Lincoln Aviator vehicles equipped with a 3.0L EcoBoost hybrid engine may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P0A1E stored in the powertrain control module (PCM). The vehicle may be unable to enter electric-only drive modes as expected during normal drive cycles. This may be due to the belt integrated starter generator (BISG). For vehicles with this condition, follow the necessary Pinpoint Test in Workshop Manual (WSM), Section 303-06 for DTC P0A1E and repair the vehicle as directed. Note that previous replacement of the BISG does not negate the need for subsequent BISG replacements if directed to do so by the appropriate Pinpoint Test diagnostics. Engineering is investigating this BISG quality concern. Monitor PTS for updates regarding this investigation.
SSM 550582026-08-03. Service bulletin. Some 2025-2026 Maverick vehicles built on or before 05-Dec-2025 and 2024-2026 Nautilus vehicles built on or before 04-Sep-2025 may exhibit limited power and display "Stop Safely Now" or "Service Vehicle Soon" stored in the message center after start up with diagnostic trouble codes (DTC) P0A5D, P0A60, P0A63, P0A6F, P0A72, P0A75, and/or P0E52 stored in the inverter system controller (SOBDMC). The Ford Diagnostic and Repair System (FDRS) may refer to this module as the "Secondary On-Board Control Module C". If the vehicle exhibits these conditions, replace the inverter system controller. Refer to Workshop Manual, Section 307-01B. For claiming, use causal part 7B012 and labor operations 12651D and 12651D58. NOTE: This article does not remove any RVC, Prior Approval or Warranty and Policy requirements for component replacement.
TSB 26-23492026-08-03. Service bulletin. This bulletin supersedes 25-2415. Reason for update: To add production build dates of the right-side engine valve cover. Some of the vehicles listed in the Model statement above may exhibit oil consumption and blue smoke from the tailpipe. This may be due to the sealing process of the positive crankcase ventilation (PCV) baffle which is part of the valve cover assembly.
