Lincoln filed this with NHTSA as a service bulletin dated Oct 2, 2025, received Oct 8, 2025, about the service brakes. It names 2 model years (2024–2025).

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 Nautilus vehicles may exhibit a grunt-type noise from the front brakes during initial brake applications that goes away after the brakes warm-up. A video demonstrating this condition is available on PTS for 2024-2025 Nautilus under the Service Tips Tab > Reference Guides > Front Brake Grunt Video. For vehicles that exhibit a noise comparable to the video only, refer to the following direction depending on vehicle build date.<br /><br /> * Vehicles built on or before 13-Jun-2024, that have previously had front disc brake rotors replaced with part number PZ1Z-1125-B: Engineering is investigating further brake noise improvements with a solution targeted for late Q4 2025. This condition does not affect vehicle durability and no additional diagnosis or service should be expected to impact this condition at this time.<br /><br /> * Vehicles built on or before 13-Jun-2024, that have not had front brake service: replace both front brake disc rotors with part number PZ1Z-1125-B. Refer to the Workshop Manual (WSM), Section 206-03 Front Disc Brake > Removal and Installation.

Read by machine from the document NHTSA serves (1 page), read Sep 30, 2026. A part number is shown only where it matches Lincoln’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 64 complaints with NHTSA since 2015. 4 of them name Service Brakes — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
12/21/24 Took delivery of vehicle 03/17/25 Called Lincoln to schedule service after brakes began grinding. 03/19/25 Took vehicle in for service - Brake rotors began grinding shortly after purchase. Such grinding causes anxiety about safety of the vehicle on the road. Took vehicle back to dealership where they validated the issue.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 54264 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 54264 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 54264 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: built on or before 13 Jun 2024; built on or after 14 Jun 2024 — the build date is on the certification label in the driver’s door jamb.
