Some 2022\-2024 Maverick hybrid vehicles may exhibit various electrical symptoms and/or a no crank/no start condition related to an intermittent 12V battery drain that has discharged the 12V battery. This may be due to the software in the anti\-lock brake system \(ABS\) module. To correct this condition, download and run the "ABS \- Anti\-lock Brake System \(ABS\) Module Software Update" and "ACCM \- Air Conditioning Control Module \(ACCM\) Software Update" applications using the latest software level of the Ford Diagnosis and Repair System \(FDRS\) scan tool. For claiming use causal part 2005 and labor operations 10654C and 12651D along with MT2005SSM up to 0.7 hours for the ABS, ACCM, PCM, and SOBDMC as needed.

- [SSM 54632](/bulletins/11029932.md), 2026-03-11, Service bulletin: UNKNOWN OR OTHER; SERVICE BRAKES; FUEL/PROPULSION SYSTEM. Some 2022\-2024 Maverick hybrid vehicles may continue to exhibit a no crank/no start condition due to a 12V battery drain after performing the air conditioning control module \(ACCM\) software update. This may be due the brake pad self\-adjustment routine being run by anti\-lock brake system \(ABS\) module software. Inform customers engineering is aware of this condition and is currently developing an ABS module software update that is expected to be available in late Q2 of 2026. To avoid this 12V battery drain condition, inform customers that they can apply the parking brake when the vehicle is turned off. This will prevent the ABS module from running the self\-adjustment routine. \<br /\>\<br /\> If a vehicle comes in for this condition and ABS software is not suspected, refer to the "Discharged Battery/12\-Volt Battery Drain Check" General Service Bulletin \(GSB\) and monitor Professional Technician System \(PTS\) for additional information. Schedule service appointments for customers once the repair becomes available. If a vehicle exhibits this concern, submit a Global Concern Report \(GCR\).
