Over-the-air update DDM-26.21.5 Nautilus

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 550812026-08-20. Service bulletin. Some 2024 Nautilus vehicles built on or before 23-Jan-2024 may exhibit a condition where the rear door power windows are locked when the child lock is off, and the rear door power windows are unlocked when the child lock is on. This may be due to the software in the body control module (BCM). To correct this condition, download and run the "BCM - Body Control Module (BCM) Software Update" application using the latest software version of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 15604 and labor operations 12651D and BCM.
SSM 548292026-05-19. Service bulletin. Some 2024-2026 Nautilus and 2025-2026 Explorer/Aviator vehicles equipped with power autofold exterior mirrors may exhibit concerns with the passenger mirror not automatically folding in or out at times, while the driver side mirror automatically folds properly. This may be due to the software in the driver door module (DDM) and passenger door module (PDM). To correct the condition, reprogram the DDM and PDM using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 14B291 and labor operation MT14B291SSM up to 0.4 hours.
SSM 545812026-02-17. Service bulletin. Some 2024-2026 Nautilus and 2025-2026 Explorer/Aviator vehicles equipped with power folding mirrors may exhibit concerns with the auto folding mirror functionality not matching the status selected by the switch in the center display screen menu. Examples include auto folding not operating when the switch is enabled and/or auto folding continuing to function when the switch is disabled. This may be due to the software in the driver door module (DDM) and passenger door module (PDM). Power folding mirror operation from the physical button is not affected by this condition. Inform customers that engineering is currently working on a solution for this condition that is expected in Q4 2026. Replacement or reprogramming of the accessory protocol interface module (APIM), DDM, or PDM will not resolve this condition. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available.<br /><br /> If the vehicle exhibits this condition, submit a Vehicle Concern Report.
