NHTSA's summary
Some 2023-2026 Corsair vehicles may exhibit a concern when changing the fan speed, the fan speed display icon (OFF/AUTO/fan speed number) changes to a different language character or symbol. This may be due to the accessory protocol interface module (APIM) software. Replacement or reprogramming of the APIM will not resolve this condition. Inform customers that engineering is currently working on a solution for this condition and will be released via software updates delivered over-the-air (OTA) expected Q4 2025. Software will update automatically if vehicle connectivity is enabled in the vehicles settings. Schedule a service visit for customers who have disabled vehicle connectivity or who report that they did not receive the update by October 2025. Monitor Professional Technician System (PTS) for additional information.

| SSM 55221 | 2026-10-12. Service bulletin. For 20222026 vehicles equipped with a 8F35 transmission, a revision to the Road Testing Vehicle procedure has been made in the WSM, Section 307-01 > Diagnosis and Testing. This updated procedure improves the diagnosis of customer reported transmission concerns and aids in locating the proper root cause. During diagnosis and testing, details regarding whether the condition is more prevalent when the vehicle is hot or cold, throttle percentage at the time of occurrence, vehicle speed, the specific shift involved, and whether the issue occurs during transmission engagements (N>R, N>D, R>D, and/or D>R) should be noted in the warranty claim. Engineering requests including these detailed operating conditions that will significantly assist with root cause analysis. Diagnosis, testing, and repair should use established labor times outside this article. |

| SSM 55031 | 2026-07-28. Service bulletin. 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 |
