What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2024 Mustang vehicles may exhibit a condition where a new lap timer session does not start at lap 1, the lap timer results are not available and/or the lap timer results button is not selectable. This may be due to the SYNC module (APIM) software. Replacement or reprogramming the APIM will not resolve this condition. Inform the customers that engineering is currently working on a solution for this condition and will be released via Ford Power-Up software updates delivered Q1 2024. 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 in Q1 2024. Monitor OASIS for additional information.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 51896 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 51896 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 51896 cover?
The manufacturer filed it against 1 model year: 2024 Ford Mustang. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
