Lincoln filed this with NHTSA as a service bulletin dated Mar 11, 2026, received Mar 18, 2026, about the seats. It names 3 model years (2024–2026). 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

The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 54647 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 54647 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 54647 cover?
The manufacturer filed it against 3 model years: 2026 Lincoln Nautilus, 2025 Lincoln Nautilus, 2024 Lincoln Nautilus. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2024–2026 Nautilus: built on or before 6 Nov 2025 — the build date is on the certification label in the driver’s door jamb.
