What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2025 Navigator vehicles equipped with second row power seats (minor feature code BYBAL) may exhibit a symptom where the second row seat control switch does not move the seat forward or backward. There may also be diagnostic trouble code (DTC) B167F:11 stored in the rear LH power seat control module (SCMK) and/or the rear RH seat control module (SCML). To confirm a vehicle is built with minor feature code BYBAL, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS). This may be due to the configuration of the SCMK and/or SCML modules. To resolve this condition, download and run the configuration applications "SCMK - Rear LH Power Seat Control Module ÝSCMK¨ Configuration" and the "SCML - Rear RH Power Seat Control Module ÝSCML¨ Configuration" using the latest version of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 14F042 and labor operations 12651D and 12651D4.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 54226 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 54226 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 54226 cover?
The manufacturer filed it against 1 model year: 2025 Lincoln Navigator. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
