Service bulletin SSM 53867

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.

NHTSA's summary

Some 2025 Expedition/Navigator vehicles may exhibit diagnostic trouble code (DTC) B1557:31 in the rear gate trunk module (RGTM) when a diagnostic self-test is performed. If no other symptoms, DTCs or conditions are identified, no further action is required. Replacement and/or reprogramming of the RGTM will not resolve this condition.

SSM 552292026-10-13. 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.
SSM 552202026-10-12. 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
DDM-PDM-26.21.7 Exped&Nav2026-10-02. Over-the-air update. Quality improvements include: -Software update to improve responsiveness of the door control system after the vehicle enters a low-power state
DSM-26.5.7.2 Exped&Nav2026-10-02. Over-the-air update. Quality improvements include: -Steering column memory calibration update to minimize unnecessary contact with mechanical hard stops
TSB 26-2358 V22026-10-01. Service bulletin. Some of the vehicles listed in the Model statement above equipped with one-touch up/down windows may exhibit a condition where a window does not respond to one-touch controls, does not open all the way and/or bounces back when using the one-touch close function.
SSM 552082026-09-30. Service bulletin. Some 2024-2026 F-150, 2025 Explorer/Aviator, 2025-2026 Expedition/Navigator, or 2026 F-Super Duty vehicles may exhibit diagnostic trouble code (DTC) U211B:43:48 stored in the body control module (BCM) when performing a Self-Test. This DTC sets due to an internal BCM timing issue during the self-test process. This specific code has no customer impact and does not cause any drivability concerns or warning messages. Clearing DTC U211B:43:48, reprogramming the BCM, or replacing the BCM is unlikely to prevent this DTC from setting. This DTC does not trigger a condition covered under warranty. Note: This guidance only applies to U211B with the specific failure byte 43 in status 48. Any other trusted real-time operation network (TRON) DTCs or different failure bytes associated with U211B are still applicable and technicians must follow Workshop Manual (WSM) normal diagnostics for those DTCs.
SSM 551982026-09-30. Service bulletin. Some 2025-2027 Navigator vehicles equipped with multi-contour seats (minor feature code BYBAL) may exhibit a condition where the second-row seat does not return to the latched position (under power) after pressing the power return button (located on the outboard side of the seatback). To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS). This may be caused by an occupant pulling the manual release strap. The manual release strap is intended to be used in emergency situations only where power seat operation is not available. Pulling the manual release strap disengages the seat pitch motor clutch. To correct the condition, the seat pitch motor clutch must re-engage with the seating system. Starting with the seat in the rearward position, press the power seat pitch button once and release it. While the seat is in motion, gently guide the headrest and seatback downward, moving the seat approximately halfway down toward the strikers (without
SSM 551942026-09-30. Service bulletin. Some 2021-2024 Mustang Mach-E, 2025-2026 Navigator and 2024 F-150 vehicles may exhibit inoperative welcome/approach detection lights. This may be due to the body control module (BCM) software. To correct the condition, download and run the "BCM - Programmable Module Installation (PMI)" application using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. If the condition persists after PMI, refer to Workshop Manual (WSM), Section 417-01 for normal diagnostics and repair as necessary outside of this article. For claiming, use causal part 15604 and labor operations 12651D and BCM.
TSB 26-24232026-09-29. Service bulletin. This bulletin supersedes 26-2280. Reason for update: To add 2027 vehicle models, update the Parts list to change the tape, and revise Step 4 to change the tape and wrap an additional wiring harness. Some of the vehicles listed in the Model Statement above may exhibit a concern where the horn intermittently sounds when turning the steering wheel. This may be due to incorrect routing of a wire harness in the steering wheel, a loose strand of wire protruding from a wire harness and grounding the driver airbag, and/or a concern with one of the driver airbag mounting points.
RCM-26.AD Expedition&Navi2026-09-28. Over-the-air update. Quality improvements include: -Restraints Control Module update to implement robust power-on reset logic.
