This may be due to the software in the driver front seat module (DSM). Replacing components and reprogramming software will not resolve this issue. Inform customers that engineering is currently working on a software solution for this condition that is expected to be available by Q4 2026. If a vehicle comes in for this condition, inform the customer that powering the vehicle off for 5 minutes with all of the doors closed will temporarily restore operation of the power running boards. Once available, 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 November 2026.
