Service bulletin SSM 49886

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 2021 F-150 PowerBoost vehicles may exhibit the fuel door release tappet separated from the fuel door housing, slow fuel fill, fuel spit back during refueling, a message in the cluster that states Close Fuel Door To Avoid Check Engine Light and/or diagnostic trouble code (DTC) P04B5 stored in the powertrain control module (PCM). This may be due to opening the fuel door without pressing the fuel door release button. Prior to following normal diagnostics, first check that the fuel door release tappet is properly installed into the fuel door and that the fuel door closes properly and opens when using the fuel door release button. If the tappet has separated from the fuel door press the fuel door release button to eject the tappet from the latch then reinstall the tappet into the fuel door by pressing it into place with features aligned with the fuel door.

PT-26.25.5 F-1502026-08-04. Over-the-air update. 25S75 Recall remedy -Powertrain Control Module update to introduce logic to prevent low pressure fuel pump binding and maintain fuel flow to the engine.
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 550312026-07-28. Service bulletin. Some 2021-2026 Ford/Lincoln vehicles may exhibit various symptoms including but not limited to the auto start/stop system not operating as intended with a "Check Charging System" message in the instrument panel cluster (IPC) while the charging system is operating properly with no charging related diagnostic trouble codes (DTC) stored. This may be due to someone using an aftermarket programmer to change the body control module (BCM) configuration to disable the auto start/stop system or perform other unsupported programming modifications. To correct this condition on F-150 and Bronco vehicles, download and run the Ford Diagnosis and Repair System (FDRS) application titled "BCM-Charging System Configuration Correction". Running this application will determine if the BCM configuration was modified by the customer and if so, provide the option to return the configuration back to factory settings. For other vehicle models exhibiting concerns related to unsupported aftermarket BCM programming, submit a Technical Support Request (TSR) requesting support to revert the BCM configuration

SSM 543172025-10-28. Service bulletin. Some 2021-2025 F-150, 2022-2025 Expedition/Navigator, 2023-2025 F-Super Duty, 2024-2025 Ranger and 2026 Transit vehicles may exhibit a discharged battery and/or a no crank/no start condition. The vehicle may also exhibit a clicking noise from the trailer module (TRM) while the vehicle is off. This may be due to software in the TRM.<br /><br />Verify the TRM software part number in the vehicle using Ford diagnosis and repair system (FDRS) to be PC3T-19J297-BF, PC3T-19J297-FF, ML3T-19J297-CD or ML3T-19J297-GD. To confirm a vehicle is equipped with a certain software level, review the software information by hovering over the "Diagnostics" tab in Professional Technician System (PTS) and selecting "Vehicle Software". If one of the listed software part numbers is present, follow the Service Procedure to reprogram the TRM. For vehicles with any other software part number in the TRM, refer to Workshop Manual (WSM), Section 414-01 to continue with normal diagnostics outside of this article. For claiming use causal part 19H332 and labor operation 12651D and 12651D4 of the Service Labor Time Standards (SLTS)
SSM 517582023-07-03. Service bulletin. Some 2021 F-150 vehicles equipped with a 3.0L Diesel may exhibit an oil change minder in the IPC staying at 100%. This may be due to the software in the IPC. Engineering is currently investigating this concern. Inform the customer they can continue to drive the vehicle. Monitor OASIS for additional updates.
TSB 22-23882023-01-05. Service bulletin. Some 2021-2022 F-150 Raptor vehicles built on or before 06-Jun-2022 may experience a rattle noise from the exhaust at the exhaust tailpipe actuators. This may be due to the exhaust tailpipe actuator valves rattling inside the muffler assembly. To correct the condition, follow the Service Procedure to reprogram the powertrain control module (PCM) and install new exhaust tailpipe actuator valve springs on the exhaust tailpipe actuator valves.
SSM 497852021-06-01. Service bulletin. Some 2021 F-Super Duty and 2021-2022 E-Series vehicles equipped with a 6.2L or 7.3L gasoline engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0457 stored in the powertrain control module (PCM). This may be due to a loose fuel filler cap. The fuel filler cap design has changed, requiring multiple turns to seal properly. Advise the customer to turn the fuel filler cap clockwise until there is at least one audible click to seal properly. For further diagnostics, refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual, pinpoint test HX.
