- Some 2027 Expedition/Navigator vehicles equipped with power running boards built on or before 13-Sep-2026 may exhibit an intermittent condition where the power running boards are unable to deploy or retract with a "Power Running Board Fault" message in the instrument panel cluster (IPC). Diagnostic trouble codes (DTC) C1008:15 and/or C1009:15 may be stored in the driver seat module (DSM). DTC U0208 and/or U0244 may also be stored in various other modules. Other DSM functions may be affected such as heated/cooled/memory seats. This may be due to the software in the DSM. If offline, DSM communication can be restored by cycling the power seat switch or performing a power reset to the DSM. DSM software will update automatically if vehicle connectivity is enabled in the vehicles settings. Schedule a service visit for customers who don't want to wait, or have disabled vehicle connectivity, or report that they did not receive the update by December 2026.
