What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 159 complaints with NHTSA since 2015. 21 of them name Engine — 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.
In Lincoln's own words the lithium batteries are flawed and can cause a short circuit which can lead to a fire. This could lead to grave danger to life. I keep my car in my garage which could lead to a house fire and harm to my family. Their original temporary fix was to set the charging system to stop at 80%.

On May 10 a lighted wrench appeared on the instrument panel. The car felt as if I was loosing power. May 12 I got in the car, the wrench and check engine lights were both on. Called the dealer service department. They told me the car is not safe to drive as it cannot accelerator and will go into "limp mode".

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 54386 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 54386 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 54386 cover?
The manufacturer filed it against 5 model years: 2025 Lincoln Corsair, 2024 Lincoln Corsair, 2023 Lincoln Corsair, 2022 Lincoln Corsair, 2021 Lincoln Corsair. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
