Some 2024 Mustang vehicles may exhibit a Check Rear Seat For Occupants pop up message on the center display screen and audible alarm for a brief period of time when the ignition is switched to OFF. 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 Ford Power-Up software updates delivered over-the-air (OTA) expected in 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.
