Service bulletin SSM 52077

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2024 Mustang vehicles may exhibit a Pre-Collision Assist Not Available message and a Pre-Collision Assist Not Available indicator displayed in the IPC with DTC U023A stored in the steering column control module (SCCM) after the vehicle is remote started. The message and indicator should go away and normal operation of the pre-collision system should resume once the vehicle is shut down and then restarted using the push button start. This may be due to a low power mode issue with image processing module A (IPMA). To confirm the pre-collision system is operating properly, turn on the vehicle using the push button start (do not use remote start), the Pre-Collision Assist Not Available pop-up message and indicator should no longer be present. If the error message and indicator are not present when starting the vehicle using the push button start (do not use remote start), replacement or reprogramming of the IPMA is not necessary. Inform customers that engineering is currently working on a solution for this condition that is expected in January 2024. If the Pre-Collision Assist Not Available message and indicator do not clear after shutting down the vehicle and then starting the vehicle using the push button start, follow the appropriate section of the Workshop Manual (WSM) to diagnose the vehicle. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available

Other bulletins for the same vehicles and component
SSM 543132025-10-28. Service bulletin. Some 2020-2025 various Ford and Lincoln vehicles equipped with blind spot information system (BLIS) may experience an inoperative blind spot monitoring with a "Blind Spot System Fault" message displayed in the instrument panel cluster (IPC). This may also be accompanied by diagnostic trouble codes (DTCs) B118C:11 and/or B118C:15 stored in the driver door module (DDM), and/or B118D:11 and/or B118D:15 stored in the passenger door module (PDM). This may be due to the wiring connector from the mirror to the BLIS module. If diagnostics lead to an internal mirror wiring harness fault, a new lower level BLIS light pigtail is now released for service. It is not necessary to replace the exterior mirror assembly. Use part number SC3Z-14A411-B to resolve the concern.
TSB 24-20472024-03-07. Service bulletin. Some 2024 Mustang vehicle's quiet start feature may be inoperative during a remote start event. This may be due to the software level of the powertrain control module (PCM). To correct this condition, perform the Service Procedure below to reprogram the PCM to the latest software level using the Ford Diagnosis and Repair System (FDRS).
SSM 522862024-03-05. Service bulletin. Some 2024 Mustang vehicles built on and before 08-Feb-2024 may exhibit an intermittent no crank/no start condition with various loss of communication diagnostic trouble codes (DTCs) stored in various modules and multiple illuminated warning indicators such as: anti-lock brake system (ABS) warning indicator, parking brake (red) indicator, brake warning indicator, parking brake (yellow) warning indicator and/or parking brake (red) indicator and/or stability-traction control indicator displayed in the instrumental panel cluster (IPC).
