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.

| SSM 55073 | 2026-08-11. Service bulletin. Some 2021-2026 Bronco vehicles may require the removal and installation of the transfer case for various reasons. Installation requires Loctite® 243 adhesive applied to the mounting bolt threads in the transmission. Make sure that the mating faces are clean and dry. Tightening the mounting bolts also requires an updated two-stage tightening sequence. Workshop Manual (WSM), Sections 307-07C/D and 308-07C/D Installation > Transfer Case have been updated to reflect this change. |

| SSM 55044 | 2026-07-27. Service bulletin. Some 2025-2026 Bronco/Ranger vehicles may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTC) P2122, P2123, P2127, P2128, and/or P2138 stored in the powertrain control module (PCM). The vehicle may or may not exhibit a perceived lack of power intermittently. This may be due to an issue with the following connectors associated with the accelerator pedal position (APP) sensor circuits: -C115B -C175B -C2040 Replacement of the accelerator pedal may not resolve this concern. Perform a wiggle test of the connectors while the engine is at normal operating temperature. Perform a visual inspection of the connectors as well as a terminal fit test using the appropriately sized flex probe. Repair as necessary. Refer to Wiring Diagram Cell 005. If no concerns are found, refer to Workshop Manual (WSM), Section 310-02 for normal diagnostics. |
| TSB 26-2301 | 2026-07-01. Service bulletin. Some of the vehicles listed in the Model statement above may require the replacement of the ambient air temperature sensor for various concerns. DTCs P0071, P0072, and/or P0073 may be present in the powertrain control module (PCM). |
| TSB 26-2291 | 2026-06-22. Service bulletin. This bulletin supersedes 26-2006. Reason for update: update the Parts list to correct the ambient air temperature service part number. Some vehicles listed in the model statement above may require the replacement of the ambient air temperature sensor for various concerns. DTCs P0071, P0072, and/or P0073 may be present in the powertrain control module (PCM). |
| SSM 54902 | 2026-06-09. Service bulletin. For 20202026 vehicles equipped with the 10R60 transmission, a new Transmission Clutch Circuit Leak Test has been introduced in the Ford Diagnosis and Repair System (FDRS). This test utilizes the pressure and vacuum transducer (PVT) when available. Workshop Manual (WSM) updates related to this diagnostic procedure are planned for release in Q4 2026. The new test improves the accuracy of detecting leaks within transmission fluid circuits and replaces the previous air check method. The previous air check procedure has been shown to produce a high rate of false positives, which may lead to unnecessary repairs when no actual leak is present. Accordingly, the air check procedure is not to be used for diagnosing internal transmission hydraulic leaks or as justification for transmission replacement. |
