Description In some of the affected vehicles, the rear right-hand axle shaft may have been manufactured without properly completing the electromagnetic induction heat treatment process, making the axle shaft susceptible to fracture. Safety Risk A fractured rear axle shaft could result in a loss of motive power while driving, or vehicle rollaway when the vehicle is placed in park and the parking brake is not applied. Either of these scenarios can increase the risk of a crash. Remedy Parts are now available to repair your vehicle. Ford Motor Company has authorized your dealer to inspect and replace your right rear axle shaft free of charge. Next Steps Contact your dealer for more information to schedule the free service.

Incident

Dec 15, 2025

Some 2021-2026 Ford/Lincoln vehicles may exhibit various symptoms including but not limited to the auto start/stop system not operating as intended with a "Check Charging System" message in the instrument panel cluster (IPC) while the charging system is operating properly with no charging related diagnostic trouble codes (DTC) stored. This may be due to someone using an aftermarket programmer to change the body control module (BCM) configuration to disable the auto start/stop system or perform other unsupported programming modifications. To correct this condition on F-150 and Bronco vehicles, download and run the Ford Diagnosis and Repair System (FDRS) application titled "BCM-Charging System Configuration Correction". Running this application will determine if the BCM configuration was modified by the customer and if so, provide the option to return the configuration back to factory settings. For other vehicle models exhibiting concerns related to unsupported aftermarket BCM programming, submit a Technical Support Request (TSR) requesting support to revert the BCM configuration

Some 2025-2026 Bronco/Bronco Sport/Corsair/F-150/F-Super Duty/Maverick/Mustang/Mustang Mach-E/Ranger vehicles may exhibit a no audio/sound condition. This may be due to the software in the audio control module (ACM). To determine if it is a software concern, disconnect the vehicle's 12-volt battery cables for 10 minutes and reconnect. If the concern is still present, continue with normal diagnostics in Workshop Manual (WSM), Section 415-00 Information and Entertainment System > General Information > Diagnosis and Testing and repair as necessary outside of this article. If the no audio/sound concern is resolved, reprogram the ACM using the latest software level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 18C869 and labor operations 10654C, 12651D and 12651D4.

Some 2023-2025 Mustang Mach-E and 2024-2026 F-Super Duty vehicles equipped with a 360-degree camera may exhibit a distorted or corrupted 360-degree camera image in the center display screen, but the rear-view camera image is operating correctly. To restore the 360-degree camera image, download and run the "IPMA - Reset the Image Processing Module A (IPMA) Calibration Data" application using the Ford Diagnosis and Repair System (FDRS) scan tool. Then download and run the "IPMA - 360 Degree View Camera Alignment" application. Inform customers that they can continue to drive the vehicle and engineering is currently working on a software solution for this condition that is expected in Q3 of 2026. Replacement or reprogramming of the IPMA will not resolve this condition. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available. If a vehicle exhibits this condition, enter a vehicle identification number (VIN) and click the "Submit Global Concern Report (GCR)" link at the upper right of the PTS

Some 2023-2026 F-Super Duty vehicles equipped with a 10R100 or 10R140 transmission may exhibit an intermittent failure to engage forward or reverse gears and/or a loud whining noise. Additionally, the driver will be able to shift back to park. This may be due to PCM software being unable to command the transmission solenoid clutch actuators when the battery has a low state of charge (SoC) and/or the vehicle has been jump started. To restore proper transmission functionality, charge the battery as stated in the Workshop Manual (WSM), Section 414-01 Charging System > General Information. Cycle the ignition on then off and leave the vehicle off for 5 minutes to confirm the condition is no longer present. To prevent this issue from reoccurring, refer to the Owner's Manual > Storing Your Vehicle > Preparing Your Vehicle for Storage > 12V Battery. Replacement of transmission components will not resolve this condition. Inform the customer that the condition has no impact on transmission durability. For claiming, use causal part 12A650 and labor operations 12650D, 12650D45, and 12650D81.
