Service bulletin TSB 25-2621
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 55241 | 2026-10-13. Service bulletin. Some 2025-2027 Aviator vehicles may exhibit a "Door Fault Service Required", "Transmission Not In Park" and/or "Hill Start Assist Not Available" message in the instrument panel cluster (IPC) with diagnostic trouble code (DTC) B1262:92 stored in multiple door latch control modules (DCME, DCMF, DCMG, and/or DCMH). DTC U0504 may also be stored in the gearshift module (GSM). This may be due to the software in the door latch control modules. To correct this condition, download and run the following applications using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool.<br /> "DCME - Door Control Module E (DCME) Software Update"<br /> "DCMF - Door Control Module F (DCMF) Software Update"<br /> "DCMG - Door Control Module G (DCMG) Software Update"<br /> "DCMH - Door Control Module H (DCMH) Software Update"<br /> For claiming use causal part 54219A65 and labor operation MT54219SSM up to 0.5 hours. |

| SSM 55240 | 2026-10-13. Service bulletin. Some 2021-2024 Bronco vehicles may exhibit an illuminated red brake warning indicator with diagnostic trouble code (DTC) C0049:01 stored in the anti-lock brake system (ABS) module. This may be due to pin fitment at the brake fluid level sensor connector. To resolve this concern, replace the brake fluid reservoir and replace the brake fluid level sensor electrical connector C1052 with service pigtail wiring kit 3U2Z-14S411-BXAB. For claiming, use causal part 2L210 and labor operations 2140A and 2219D45WR. |
| SSM 55239 | 2026-10-13. Service bulletin. Some 2023-2026 F-Super Duty vehicles equipped with a trailer brake control module and built on or before 08-May-2026 may exhibit a "Trailer Disconnected" message after cycling the ignition off and back on with a trailer connected. This may be due to the presence of an integrated battery charger on a trailer equipped with electric over hydraulic brakes. If trailer functionality is restored after unplugging and plugging the trailer connector back in while the ignition is on, this condition can be corrected by downloading and performing the "Trailer Brake Configuration" application using the latest software version of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 19H332 and labor operations 12651D and 12651D4. Workshop Manual (WSM), Section 417-01 Exterior Lighting > Diagnosis and Testing > Trailer Lamps > Pinpoint Test G The Message Center Displays A False Trailer Disconnected Message When A Trailer Is Connected To The Vehicle - Only For Electric Over Hydraulic (EOH) Equipped Trailers When Vehicle Trailer Brake Type Setting Is Set To Electric Over Hydraulic has bee |
| SSM 55229 | 2026-10-13. Service bulletin. Some 2025-2027 Navigator vehicles equipped with a second row floor console may experience a sliding cover over the cup holders that has become separated. Engineering is aware of this condition and is investigating a service solution that will enhance the performance of the cup holder slider. This solution is expected to be available by the end of Q1 2027. If the customer is not willing to wait for the enhanced service solution, replacement of the second row floor console cup holder assembly is acceptable. Note that the replacement of the cup holder assembly will have similar performance attributes for the slider as the original cup holder assembly that is being replaced. Should the customer choose to wait for the enhanced service solution, schedule an appointment with the customer when the repair is made available in Q1 2027. Monitor Professional Technician System (PTS) for updates. |
| TSB 26-2375 v2 | 2026-10-13. Service bulletin. NOTE: This bulletin has been updated, refer to the change log at the bottom for details. Issue: Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: • Poor shift quality • Illuminated powertrain malfunction (wrench) indicator with DTCs P2704 and P0771 stored in the PCM / TCM . This may be due to a calibration in the TCM and/or wear between the input shaft and the E clutch hub causing theinput shaft O-rings to become damaged resulting in an open E clutch circuit. Action: For vehicles that meet all of the criteria in the Issue and Model statements, follow the Service Procedure toreprogram the PCM / TCM and/or replace the E clutch hub and input shaft O-rings |
| SSM 55220 | 2026-10-12. Service bulletin. Some 2024-2026 Nautilus and 2025-2026 Explorer/Aviator/Expedition/Navigator vehicles may experience Android Auto connection or general Bluetooth pairing concerns for both Android and IOS after an APIM software update. This may be due to the APIM software. To temporarily correct the issue:<br /><br /> * For Android Auto related issues: Clear Android Auto app storage in the center display screen. Vehicle Settings > Settings > Apps > Android Auto > Clear Storage. <br /> * For general Bluetooth connectivity issues: Clear Contacts Storage app storage in the center display screen. Vehicle Settings > Apps > Uncheck hide system apps > Contacts Storage > Clear Storage.<br /><br /> If the condition persists, perform a master reset from the center display screen, remove the vehicle from the phone, then re-pair the device.<br /><br /> If the condition continues to persist, refer to Workshop Manual (WSM), Section 415-00 for normal diagnostics and repair as necessary outside of this article.<br /><br /> If the condition is resolved, inform customers that engineering is currently working on a permanent solution |
| SSM 55218 | 2026-10-06. Service bulletin. For 20202026 vehicles equipped with the 10R140 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. |
| TSB 26-2325 | 2026-10-05. Service bulletin. Some of the vehicles listed in the Model statement above may exhibit a front courtesy lamp that is inoperative. This may be due to a concern with the front courtesy lamp light module. |
