NHTSA's summary

Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module (BCM). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how to retrieve the master code. This guide is located under the Workshop Manual tab > Accessories > Installation > Wireless RF Keypad Diagnosis Guide > PPT C > Step C2.<br /><br /> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad. The integrated wired keypad cannot be installed on vehicles not equipped from the factory with a wired keyless entry k

SSM 552402026-10-13. 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 552392026-10-13. 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.

SSM 552212026-10-12. 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 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
