Service bulletins for the 2026 Ford Bronco

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.

SSM 551182026-09-01. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER; STRUCTURE:BODY. 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.
SSM 550792026-08-20. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER. Some 2025-2026 Bronco vehicles equipped with a 7 speaker audio system (minor feature code IDBAL) may exhibit diagnostic trouble codes (DTC) B128A:01, B128A:11, B128A:12, B128A:13, B1288:11, B1288:12 and/or B1238:17 stored in the audio front control module (ACM) with no customer facing symptoms related to those DTCs. Clear the DTCs and if the DTCs return with no customer facing symptoms, this condition may be due to the ACM software. Replacement of the ACM and/or speakers will not resolve this condition. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q4 2026. Continue to 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 the vehicle identification number (VIN) and click the "Submit Global Concern Report (GCR)" link at the upper right of the PTS "Vehicle ID" screen. Fill out the GCR form, referencing this article number in the report.
SSM 550312026-07-28. Service bulletin. UNKNOWN OR OTHER; FUEL/PROPULSION SYSTEM; ELECTRICAL SYSTEM. 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
SSM 550442026-07-27. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM. Some 2025-2026 Bronco/Ranger vehicles may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTC) P2122, P2123, P2127, P2128, and/or P2138 stored in the powertrain control module (PCM). The vehicle may or may not exhibit a perceived lack of power intermittently. This may be due to an issue with the following connectors associated with the accelerator pedal position (APP) sensor circuits: -C115B -C175B -C2040 Replacement of the accelerator pedal may not resolve this concern. Perform a wiggle test of the connectors while the engine is at normal operating temperature. Perform a visual inspection of the connectors as well as a terminal fit test using the appropriately sized flex probe. Repair as necessary. Refer to Wiring Diagram Cell 005. If no concerns are found, refer to Workshop Manual (WSM), Section 310-02 for normal diagnostics.
SSM 550212026-07-21. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER. 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.
SSM 550092026-07-20. Service bulletin. ELECTRICAL SYSTEM; STRUCTURE:BODY. Some 2021-2026 Bronco vehicles may exhibit a "Park Brake Limited Function Service Required" message in the instrument panel cluster (IPC). This may be due to an issue with the driver door harness connector after removing and installing the removeable doors. If diagnostic trouble code (DTC) B1625:29 is stored in the driver door module (DDM), inspect connector C322C between the upper and lower door hinges that attaches to the body for proper installation and/or pin fitment. Repair as necessary. If the condition was caused by improper door installation, do not submit a claim for this condition. If no concerns are found with the connector, refer to Workshop Manual (WSM), Section 501-11 > Diagnosis and Testing for normal diagnostics.
ABS-26.11.1.2B Bronco2026-07-17. Over-the-air update. ELECTRICAL SYSTEM; UNKNOWN OR OTHER.

SSM 549922026-07-13. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER; EXTERIOR LIGHTING. Some 2024-2026 Bronco vehicles may exhibit various TRM concerns when attempting first time installation of a dealer installed accessory TRM, including one or more of the following: TRM unable to be programmed -Trailer lights inoperative -DTC U2100 stored in the TRM. This may be due to any of the following conditions:-The incorrect trailer tow kit is being installed. The TRM is model year specific. Refer to the parts catalog using the VIN and base part number 15A416 for the vehicle specific trailer tow kit.-The "TRM - Trailer Module (TRM) Configuration" application being run instead of the "Towbar Configuration" application during first time TRM installation using the Ford Diagnosis and Repair System (FDRS). Dealer installed accessory TRMs are preprogrammed and only the "Towbar Configuration" application should be run during first time TRM installation to configure the TRM properly and support proper function of trailer tow capabilities. Any attempts to program the TRM using the "TRM - Trailer Module (TRM) Configuration" application a
SSM 549492026-06-24. Service bulletin. ELECTRICAL SYSTEM; VISIBILITY/WIPER. Some 2024-2026 Bronco vehicles may exhibit a condition where short drop windows, window bounce-back, and/or one-touch open/close does not operate properly. This may be due to loss of window initialization. Replacement or reprogramming of the DDM, PDM, and/or any other components may not resolve these conditions. The short drop windows feature may be restored by performing a reset procedure as described in the Digital Owner's Manual > Windows > Using Short Drop Windows > Resetting Short Drop Windows. If the customer is experiencing an inability to fully close the window due to repeated bounce-back events, the window bounce-back feature may be overridden by performing an override procedure as described in the Digital Owner's Manual > Windows > Window Bounce-Back > Overriding Windows Bounce-Back. The one-touch open/close feature may be restored by performing a reset procedure as described in the Digital Owner's Manual > Windows > Opening and Closing the Windows > Resetting Window One-Touch. These symptoms may return after a successful reset/override
