What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 78 complaints with NHTSA since 2015. 12 of them name Electrical System — 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.

No other warnings or messages appeared on the dash, and upon restart after returning to the vehicle, the red battery light did not reappear.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 55247 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 55247 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 55247 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.
