## Other bulletins for the same vehicles and component

- [SSM 55228](/bulletins/11038440.md), 2026-10-12, Service bulletin: ENGINE; UNKNOWN OR OTHER. Some 2020\-2026 Aviator/Explorer/F\-150/Bronco/Ranger vehicles equipped with a 2.7L or 3.0L \(non\-diesel\) engine may need the front engine cover removed and reinstalled for various reasons. The Workshop Manual \(WSM\), Section 303\-01 Engine \> Removal and Installation \> Engine Front Cover service procedure has been updated to include a new essential special service tool \(ESST\) guide pin alignment tool \(303\-1790\) that is used to align the engine front cover to the engine block, preventing the O\-ring seal on the engine oil galley feed tube from getting damaged during installation.
- [SSM 55217](/bulletins/11038165.md), 2026-10-06, Service bulletin: ENGINE; UNKNOWN OR OTHER. Some 2020\-2024 Explorer/Aviator vehicles equipped with 3.0L EcoBoost/hybrid engine may exhibit blue or black exhaust smoke on startup for the first 5 minutes after an overnight cold soak with no illuminated malfunction indicator lamp \(MIL\) or powertrain diagnostic trouble codes \(DTCs\) present. This may be due to engine oil breaching the dynamic oil seals separating the bearing core from the turbine housing in the left side turbocharger assembly. There is a new, updated left side turbocharger oil supply tube equipped with an internal check valve to prevent the engine oil from entering turbine housing after the engine is off. Replace the existing left side turbocharger oil supply tube with the updated service part that includes the check valve \(service part\# L1MZ\-9T516\-B\) or latest level part. Refer to the Workshop Manual \(WSM\), Section 303\-04 Fuel Charging and Controls \- Turbocharger \> Removal and Installation \> Turbocharger Oil Supply Tube LH. For claiming, use causal part 9T516 and labor operation code 9440AL.

- [TSB 26\-2233](/bulletins/11032747.md), 2026-05-18, Service bulletin: ENGINE. This article supersedes TSB 26\-2116 to clarify the prior approval statement. Some of the vehicles listed in the model statement above may exhibit an oil leak from the oil filter adapter to engine block mounting area. This may be due to block porosity or a block crack just below the oil filter adapter near the main bearing cap outer bolt.

- [SSM 54795](/bulletins/11032565.md), 2026-05-08, Service bulletin: ENGINE; ELECTRICAL SYSTEM; POWER TRAIN. Some 2021\-2023 F\-150 vehicles equipped with a 3.5L PowerBoost engine and 2020\-2026 Explorer vehicles equipped with a 3.3L 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 software within the belt integrated starter generator \(BISG\). For vehicles with this condition, follow Pinpoint Test I: Battery Isolation/Voltage Stabilization Control Circuit Carry Outance located in the Workshop Manual \(WSM\), Section 303\-06D and repair the vehicle as necessary. Note that the BISG is on backorder status at the time of this publication and Ford is working to make parts available. Engineering is investigating this concern. Monitor PTS for updates.
- [TSB 26\-2171](/bulletins/11031490.md), 2026-04-22, Service bulletin: ENGINE. This article updates TSB 25\-2154. Reasons for update: \*Parts List \*Service Procedure to replace the output planetary carrier assembly \*Added 2023\-2024 model year vehicles Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: Shudder condition, most noticeable at speeds below 60 mph \(100 km/h\) No relevant diagnostic trouble codes \(DTC\) present Traceable shudder event with IDS/FDRS reading \*\(Figure 1\)\* This condition may be perceived/felt as an engine misfire. This may be due to a concern with the output planetary assembly.
- [SSM 54756](/bulletins/11031411.md), 2026-04-21, Service bulletin: ENGINE. 2021\-2026 Explorer vehicles equipped with the 2.3L EcoBoost engine may require air conditioning \(A/C\) compressor belt removal for various reasons. The Workshop Manual \(WSM\), Section 303\-05A Accessory Drive \- 2.3L EcoBoost \> Removal and Installation \> Air Conditioning \(A/C\) Compressor Belt procedure has been revised to eliminate cutting the A/C compressor belt to remove it. Refer to the updated procedure to reuse the belt.
