Ford filed this with NHTSA as a service bulletin dated May 30, 2024, received Jun 6, 2024. It names 54 model years across Ford and Lincoln (2021–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome vehicles equipped with SYNC4 may exhibit one or more of the following symptoms after all currently available accessory protocol interface module (APIM) software updates have been performed. - General system performance, stability, and intermittent system reboots. - Intermittent Wireless CarPlay or Android Auto function. - Phone related concerns with intermittent No Audio or Static. - Navigation/global positioning system (GPS) related concerns through CarPlay and Android Auto. - Alexa function consistency and stability. These symptoms may be due to the software in the APIM. Replacing the APIM will not resolve these symptoms for the customer. Before returning the vehicle to the customer, review the procedures within Workshop Manual, Section 415-00 and ensure the latest APIM software is installed. Refer to General Service Bulletin (GSB) 23-7146 for help determining the latest available level of software. IMPORTANT: some module software updates will only display as available on Ford Diagnosis and Repair System (FDRS) after prerequisite modules are updated. This may require the technician to update certain modules multiple times during the service visit, before the latest APIM software is accessible in FDRS. If symptoms continue after latest APIM software has been installed, inform customers that Ford is working on additional software enhancements which are expected to be delivered over-the-air (OTA) by Q4 2024 on F-150, F-150 Lightning, Mustang Mach-E, Mustang, Escape, Corsair, Expedition, Navigator, Bronco, Mustang, and 2023-2024 F-Super Duty. Software will update automatically if vehicle connectivity is enabled in the vehicle's settings. For all other vehicles with SYNC4, schedule a service visit for customers in October 2024, when the updated APIM software is expected to be available to dealers. Monitor OASIS for additional information.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52574 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 52574 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 52574 cover?
The manufacturer filed it against 54 model years across 2 brands (Ford and Lincoln): 2024 Ford Bronco, 2023 Ford Bronco, 2022 Ford Bronco, 2021 Ford Bronco, 2024 Ford Edge, 2023 Ford Edge and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
