Ford filed this with NHTSA as a service bulletin dated May 7, 2024, received Jun 3, 2024. It names 1 model year (2024).

Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2024 Mustang vehicles may exhibit at least one of the following symptoms: rear parking aid camera displaying while in drive, "Lap Timer Results" greyed out and not available and new lap timer session does not start at Lap 1 when a lap timer session is stopped, "Check Rear Seat For Occupants Alert/Alarm" on for a brief period, My Mustang hard button - no response on the vehicle's center display screen when the hard button is pressed. This may be due to the software in the accessory protocol interface module (APIM). To correct the condition, follow the Service Procedure to reprogram the APIM using the latest level of the Ford Diagnosis and Repair System (FDRS) scan tool.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 24-2129 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 TSB 24-2129 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 TSB 24-2129 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.
