# Service bulletin TSB 21\-2254

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.

- Type: Service bulletin
- NHTSA id: 10202698
- Published by NHTSA: 2021\-11\-02
- Manufacturer's number: TSB 21\-2254
- Manufacturer's date: 2021\-10\-19

## NHTSA's summary

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.

## Other bulletins for the same vehicles and component

- [SSM55059](/bulletins/11035556.md), 2026-08-03, 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 54857](/bulletins/11032924.md), 2026-05-26, Service bulletin: FUEL/PROPULSION SYSTEM. 2020\-2026 Explorer/Escape/Corsair, 2021\-2026 Bronco Sport/Bronco, 2022\-2026 Maverick, 2024\-2026 Mustang/Ranger/Nautilus vehicles equipped with a 2.0L or 2.3L 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 \- 2.0L/2.3L EcoBoost \> Removal and Installation \> Wastegate Control Actuator Linkage service procedure been added. In addition, the wastegate actuator rod \(9E408\), associated retention springs \(9342\) and retaining clips \(00817\) have been released as lower\-level components to complete the repair without replacing the entire turbocharger wastegate actuator assembly.
- [SSM 54646](/bulletins/11032252.md), 2026-05-05, Service bulletin: FUEL/PROPULSION SYSTEM; UNKNOWN OR OTHER; STRUCTURE:BODY. Some 2020\-2024 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. If diagnostics in the Workshop Manual \(WSM\), Section 501\-14 Body \> Handles, Locks, Latches and Entry Systems \> lead to fuel filler door switch replacement, install a new fuel filler door assembly ordered from depot stock to correct this condition. Suspect parts have been cleared from parts depot inventory.
- [SSM 54787](/bulletins/11032247.md), 2026-05-05, 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 54615](/bulletins/11029540.md), 2026-03-04, Service bulletin: FUEL/PROPULSION SYSTEM; ELECTRICAL SYSTEM; POWER TRAIN. Some 2020\-2026 Escape and 2021\-2026 Corsair vehicles equipped with a 2.5L engine may exhibit a fuel door that won't open with diagnostic trouble code \(DTC\) P04CA stored in the powertrain control module \(PCM\). This may be due to an open circuit on circuit SBB05 and/or a damaged splice S133. Before performing the pinpoint test for P04CA in Workshop Manual \(WSM\), Section 310\-00, inspect circuit SBB05 and splice S133 for damage such as an open circuit. Repair as necessary. Refer to Wiring Diagram, Cell 005. If no damage is found, refer to WSM, Section 310\-00 for normal diagnostics. For claiming use causal 14290 and labor operations 12650D, 12650D45, and 12650D45WR.
- [SSM 54614](/bulletins/11029539.md), 2026-03-04, 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 54425](/bulletins/11026518.md), 2025-12-10, Service bulletin: POWER TRAIN; FUEL/PROPULSION SYSTEM. Some 2020\-2026 Police Interceptor Utility hybrid vehicles may exhibit multiple warning messages, various drivability concerns and/or an illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble code \(DTC\) P061B stored in the powertrain control module \(PCM\). This may be due to the incorrect installation of additional police equipment. Equipment should only use the provided rear power access point and must not use the 12V cranking or 12V auxiliary batteries for power. The vehicle will go to sleep after the ignition key is removed and is not designed to power equipment when the vehicle is not running. If equipped, the Police Engine Idle feature can be used to allow the vehicle to securely remain idling and to power equipment. Refer to the Owners Manual.\<br /\>\<br /\> If it is determined additional equipment has not been added to the 12V cranking or 12V auxiliary batteries, continue with normal Workshop Manual \(WSM\) diagnostics, Section 303\-04C Engine \> Fuel Charging and Controls \> Diagnosis and Testing \> Pinpoint Test QE.\<br /\>\<br /\> For general upfitter installation guidelines, refer to:\<br /\>
- [SSM 54312](/bulletins/11024525.md), 2025-10-28, Service bulletin: FUEL/PROPULSION SYSTEM. Some 2020\-2026 Escape and 2021\-2026 Corsair PHEV vehicles may require inspection of the high voltage battery due to rust, scratches, curb strikes, road debris, or other minor damage. Section 414\-03A of the Workshop Manual \(WSM\) has recently been updated to improve diagnostics for such damage and provides a list of low\-level serviceable components for instances where replacement of the high voltage battery assembly is not warranted. Refer to WSM, Section 414\-03A High Voltage Battery, Mounting and Cables \> Diagnosis and Testing \> High Voltage Battery Minor Damage Inspection. The Ford New Vehicle Limited Warranty covers manufacturing defects resulting from a defect in factory supplied materials or workmanship. Please refer to the Warranty section WHAT IS NOT COVERED, which includes curb strikes and accidents.
