Lincoln filed this with NHTSA as a service bulletin dated May 16, 2026, received May 19, 2026, about the suspension. It names 2 model years (2024–2025). 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 communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Some 2024-2025 Lincoln Nautilus vehicles built on or before 17-Jul-2025 and equipped with continuous controlled damping (CCD) suspension (feature code DWAA9) may exhibit a clunk, rattle, knock, or thump noise from the rear suspension over bumps at lower speeds. To confirm a vehicle is built with a certain minor feature code, review the build information by clicking "Additional Information" under Vehicle ID Tab > Vehicle Information, or double-clicking the vehicle identification number (VIN) in the upper left corner on Professional Technician System (PTS). In some instances, the noise can be reproduced by a jounce test of the rear suspension on a level surface. This may be due to a concern with the rear shock absorbers. If a noise is confirmed from the rear shock absorbers, replace both shock absorbers. Refer to Workshop Manual (WSM), Section 204-02 > Removal and Installation > Rear Shock Absorber. For claiming, use causal part 18125 and labor operation 18125AT.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 54828 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 54828 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 54828 cover?
The manufacturer filed it against 2 model years: 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: 2024-2025 Lincoln Nautilus: built on or before 17 Jul 2025 — the build date is on the certification label in the driver’s door jamb.
