Lincoln bulletin SSM 55107
Lincoln filed this with NHTSA as a service bulletin dated Aug 20, 2026, received Sep 1, 2026, about the structure. It names 1 model year (2027). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2027 Expedition/Navigator vehicles equipped with power running boards may exhibit an intermittent condition where the power running boards are unable to deploy or retract when entering or exiting the vehicle with a "Power Running Board Fault" message in the instrument panel cluster (IPC). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 55107 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the SSM 55107 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 55107 cover?
The manufacturer filed it against 1 model year: 2027 Lincoln Navigator. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
