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.

SSM550592026-08-03. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM; UNKNOWN OR OTHER; FUEL/PROPULSION SYSTEM. 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 547872026-05-05. Service bulletin. FUEL/PROPULSION SYSTEM. Some 2020-2023 Aviator and 2025-2026 Explorer/Police Interceptor Utility hybrid vehicles may exhibit a "Refuel Error See Manual" message in the instrument panel cluster (IPC) after installing a replacement fuel filler door assembly (7827936). This may be due to a concern with the replacement fuel filler door assembly. This condition does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and Ford is currently working on a solution for this condition that is expected Q3 2026. Further replacement of the fuel filler door assembly will not resolve this condition at this time. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available.<br /><br /> If a customer vehicle exhibits this concern, submit a Vehicle Concern Report. To submit a report, click on the "Submit Global Concern Report (GCR)" link at the upper right of the PTS Vehicle ID screen (vehicle identification number ÝVIN¨ required) a

SSM 546142026-03-04. Service bulletin. FUEL/PROPULSION SYSTEM. Some 2020-2024 Explorer vehicles equipped with a 2.3L engine and 2020-2026 Explorer/Police Interceptor Utility/Aviator vehicles equipped with a 3.0/3.3L engine may require various repairs associated with the fuel tank and/or fuel pump and sender unit. Workshop Manual (WSM), Section 310-00 > Removal and Installation for the fuel tank and fuel pump and sender unit have been revised to eliminate the need to remove the driveshaft as part of the service procedure. Labor times have also been updated to reflect this WSM revision.
SSM 539822025-07-02. Service bulletin. FUEL/PROPULSION SYSTEM. Some 2020-2023 Explorer/Aviator, 2020-2025 Police Interceptor Utility, 2020-2022 Escape/Corsair, and 2022-2024 Maverick vehicles equipped with a hybrid powertrain may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P2450:00 stored in the powertrain control module (PCM). This may be due to an evaporative emission system concern or may also be caused by the customer overfilling the fuel tank. If this condition occurs, perform normal diagnosis per Workshop Manual (WSM) Section, 303-13 and repair as necessary. Inform the customer that the condition may have been caused by overfilling of the fuel tank and to not top-off the fuel tank when the fuel pump nozzle automatically shuts off for the first time. Refer the customer to the Fuel and Refueling section of their Owner Manual for additional information.
SSM 518242023-08-11. Service bulletin. FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR. 2020-2023 Explorer non-hybrid vehicles equipped with a 3.0L EcoBoost or 3.3L Duratec engine and 2020-2023 Aviator non-hybrid vehicles equipped with a 3.0L EcoBoost engine may exhibit an exhaust rattle requiring replacement of the left or right exhaust flexible pipe (5G203). The updated part locates the flexible joint portion of the pipe closer toward the catalytic converter than the originally equipped part. This is due to a design change with these replacement components which will not cause any functional issues with the vehicle.
TSB 22-24332023-01-05. Service bulletin. FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY. This article supersedes TSB 22-2176 to increase the labor operation allowance and update the part list. Some 2020-2022 Escape/Corsair vehicles built on or before 3-Jan-2022, 2020-2022 Explorer vehicles built on or before 14-Feb-2022, 2020-2022 Aviator vehicles built on or before 07-Feb-2022 and 2021-2022 Bronco Sport vehicles built on or before 3-Dec-2021 may exhibit a slow fuel fill and/or spit back condition during refueling. This may be due to the design of the fuel tank filler pipe. To correct the condition, follow the Service Procedure to replace the fuel tank filler pipe.
TSB 22-21762022-06-27. Service bulletin. FUEL SYSTEM, GASOLINE. Some 2020-2022 Escape/Corsair vehicles built on or before 3-Jan-2022, 2020-2022 Explorer vehicles built on or before 14-Feb-2022, 2020-2022 Aviator vehicles built on or before 07-Feb-2022 and 2021-2022 Bronco Sport vehicles built on or before 3-Dec-2021 may exhibit a slow fuel fill and/or spit back condition during refueling. This may be due to the design of the fuel tank filler pipe. To correct the condition, follow the Service Procedure to replace the fuel tank filler pipe.
SSM 506222022-03-30. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some 2020 - 2022 Explorer/Aviator/Police Interceptor Utility vehicles may display a distance to empty value in the instrument panel cluster (IPC) that does not correctly represent the actual fuel level of the vehicle. This may be due to excessive idling and/or a learned value in the powertrain control module (PCM) that is incorrect. To correct the condition, perform the PCM - Reset the Keep Alive Memory (KAM) application in the appropriate Ford diagnostic scan tool. For claiming, use Causal Part 12A650 and applicable labor times from Section 10 in the Service Labor Time Standards (SLTS) Manual.
TSB 21-22542021-11-02. Service bulletin. FUEL SYSTEM, GASOLINE; EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. Some 2020-2021 Escape/Corsair vehicles built on or before 30-Mar-2021 and Explorer/Aviator vehicles built on or before 09-Apr-2021 may exhibit a slow fuel fill and/or spit back condition during refueling. This may be due to the design of the fuel tank filler pipe. To correct the condition, follow the Service Procedure to replace the fuel tank filler pipe.
