What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2022 Navigator vehicles may exhibit a loss of driver seat adjustment functions after replacing the driver seat module (DSM). The accelerator and brake pedals may also move when actuating certain seat adjustment switches. This may be due to incorrect software being released into the Ford Diagnosis and Repair System (FDRS) scan tool at the time of the previous programmable module installation (PMI). The software has since been corrected on Ford servers. To correct the condition, perform Programmable Module Installation (PMI) on the DSM using the latest software level of the FDRS scan tool. For claiming, use causal part 14C708 and labor operations 12651D and 12651D4.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 54608 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 54608 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 54608 cover?
The manufacturer filed it against 1 model year: 2022 Lincoln Navigator. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
