What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2024-2025 Nautilus vehicles may exhibit an intermittent false alarm activation. This may be due to the software in the body control module (BCM). Monitor the BCM alarm event parameter identifications (PID). If ALARM_EVT_1/2/3/4 show a value of "Interior Motion Detected", reprogram the BCM using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal 15604 and labor operations 12651D and BCM. If ALARM_EVT_1/2/3/4 does not show a value of "Interior Motion Detected", refer to Workshop Manual (WSM), Section 419-01A > Diagnosis and Testing > Pinpoint Test E (False Alarm Activation) for normal diagnostics and repair as necessary outside of this article.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 64 complaints with NHTSA since 2015. 11 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.
During a short drive between and roughly 27 miles, the red battery light on the dash display illuminated just as we were turning into the Holiday/Circle K gas station in . 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 55019 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 55019 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 55019 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.
