What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2023-2026 Corsair vehicles may exhibit a concern when changing the fan speed, the fan speed display icon (OFF/AUTO/fan speed number) changes to a different language character or symbol. This may be due to the accessory protocol interface module (APIM) software. Replacement or reprogramming of the APIM will not resolve this condition. Inform customers that engineering is currently working on a solution for this condition and will be released via software updates delivered over-the-air (OTA) expected Q4 2025. Software will update automatically if vehicle connectivity is enabled in the vehicles settings. Schedule a service visit for customers who have disabled vehicle connectivity or who report that they did not receive the update by October 2025. Monitor Professional Technician System (PTS) for additional information.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 54248 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 54248 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 54248 cover?
The manufacturer filed it against 3 model years: 2025 Lincoln Corsair, 2024 Lincoln Corsair, 2023 Lincoln Corsair. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
