Service bulletin SSM 54635

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 2024-2025 Mustang Mach-E/F-150 vehicles may exhibit a crackling noise from speakers during phone calls when using wireless Apple CarPlay or wireless Android Auto. This may be due to wireless interference. To isolate the wireless interference as a possible cause, turn off the wireless projection application in SYNC Connectivity settings in the vehicle's center touch screen and connect the phone through universal serial bus (USB) cable. If the call quality issue through Apple CarPlay or Android Auto is addressed, this confirms that wireless projection was the cause. Engineering is aware of this condition and working on a software solution expected at the end of Q4 2026. As a temporary solution, customers can connect their phones with a USB cable. Reprogramming or replacement of any modules will not correct the condition. Use the "Submit Global Concern Report (GCR)" link at the upper right of the OASIS report to submit a vehicle concern report if the wireless projection is found to be the cause of the condition.

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 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.

SSM 551312026-09-02. Service bulletin. Some 2025-2026 Aviator/Explorer/Expedition/F-150/Mustang Mach-E/Nautilus/Navigator vehicles may exhibit the hands-free BlueCruise feature intermittently/consistently unavailable when BlueCruise is active and when traveling in a "Blue Zone". Speed sign recognition may also be inaccurate. If there are no active relevant diagnostic trouble codes (DTC) present and the issue persists after multiple key cycles and if the BlueCruise System Health Check passes, download and run the "TCU - Reset Telematics Control Unit (TCU) Module" application using the latest software level of the Ford Diagnosis and Repair System (FDRS). If the condition is resolved, inform customers that this may be a temporary fix and engineering is currently working on a solution expected in Q4 2026. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available. For claiming, use causal 14G229 and labor operations 12651D and 12651D4. If the condition persists after a test drive, refer to Workshop Manual (WSM), Section 419-03B for normal
SSM 551182026-09-01. Service bulletin. Some of the following vehicles: * 2023-2025 F-Super Duty built on or before 02-Feb-2025 * 2024-2026 Ranger/Bronco/Mustang * 2024-2025 F-150 built on or before 15-Jul-2025 * 2024-2025 Nautilus built on or before 16-Feb-2025 * 2025 Explorer/Aviator built on or before 01-Feb-2025 may exhibit all of the following symptoms: - "No Key Detected" message displayed on the instrument panel cluster (IPC). - Key fob does not work in the backup slot. - Remote keyless entry (RKE) (lock and unlock from the key fob) functionality will work to lock/unlock the vehicle. If the vehicle exhibits these symptoms, start the vehicle using both key fobs. If the no crank/no start condition with "No Key Detected" concern is present, reprogram both key fobs and retest. If the no crank/no start condition with "No Key Detected" is still present, replace the body control module (BCM). Refer to Workshop Manual (WSM), Section 419-10. For claiming, use causal part 15604 and labor operation MT55118SSM up to 1.8 hours.
