Ford Maverick Hybrid Owner Reports Sixth Battery After Successive Software Updates

A software remedy should have reduced the chance that a Ford Maverick Hybrid would discharge its 12-volt battery while parked. Instead, Ford followed its first update with additional repair instructions after acknowledging that some trucks could still develop a no-start condition. Against that backdrop, a Maine owner of a 2022 Maverick XL Hybrid reported on Nov. 7, 2026, that his truck had received its sixth 12-volt battery.

The owner, posting as danadams on MaverickTruckClub, said the fifth battery was an absorbent glass mat, or AGM, unit and the first to last longer than a year. He attributed that longer service partly to disabling remote start, remote locking and other convenience features. He also alleged that Ford declined to cover the problem under warranty, but no repair receipts, complete replacement dates or response from Ford concerning his individual claim were provided.

The account illustrates the ownership burden of an intermittent electrical drain, but it does not measure how common the problem is. The discussion does not identify which Ford software updates were installed on this particular truck. Other owners reported battery lives ranging from roughly four months to more than four years, indicating that the sixth-battery case cannot be applied across the Maverick Hybrid fleet.

Ford’s repair instructions evolved over two years

Ford’s dealer communications show why replacing the battery alone may not resolve every affected truck. In October 2024, Special Service Message 53087 covered 2022–2024 Mavericks with the 2.5-liter hybrid powertrain. It instructed dealers to disconnect the battery for a 12-volt reset, charge and test it, and replace it when necessary. Ford said at the time that engineers expected a software solution in the first quarter of 2025.

That update arrived in May 2025. SSM 53801 instructed dealers to update software in the air-conditioning control module on covered 2022–2025 Maverick hybrids built on or before Feb. 17, 2025. By January 2026, however, Ford advised dealers that some trucks could still experience a discharged 12-volt battery and a no-crank, no-start condition after receiving the earlier update.

Ford then identified another mechanism for certain 2022–2024 hybrids. A March 2026 message associated continuing drain with a brake-pad self-adjustment routine run by the anti-lock brake system module. Until revised software became available, dealers were told to advise affected customers to apply the parking brake after switching off the truck, preventing that routine from running.

In April, Ford instructed dealers to install anti-lock brake software and another air-conditioning control module update. Its Sept. 30 instructions repeated that repair and added updates for other modules when needed. The publicly available September service communication describes intermittent drain, electrical symptoms and no-start conditions in 2022–2024 Maverick hybrids, with anti-lock brake and air-conditioning control software among the prescribed corrections.

A small battery can disable the hybrid system

The 12-volt battery is separate from the high-voltage traction battery that supports hybrid propulsion. It supplies low-voltage electronics and enables the vehicle’s control systems to start operating. A healthy high-voltage battery therefore does not guarantee that the truck will become ready to drive if its 12-volt supply has been discharged.

Modern vehicles also keep some modules active after shutdown before placing them into lower-power sleep states. Ford’s repair sequence points to software-controlled module behavior rather than one universal battery defect: the company first addressed the air-conditioning control module, later associated some continuing cases with an anti-lock brake routine, and ultimately prescribed updates across several modules as needed.

Recall and hybrid warranty coverage have important limits

Ford’s separate battery recall, numbered 25V-019 or 25S02, does not cover Maverick hybrids. That campaign included 272,817 specified 2021–2023 Bronco Sports and 2022–2023 gas-powered Mavericks with potentially defective 12-volt batteries. Applying that recall to hybrid trucks would conflate a specified battery defect in listed gas models with Ford’s software instructions for hybrid battery drain.

Warranty duration creates another complication. Ford’s 2022 warranty guide provided bumper-to-bumper coverage for three years or 36,000 miles. The longer hybrid unique-component warranty ran for eight years or 100,000 miles and listed equipment including the high-voltage battery and DC/DC converter, but not the conventional 12-volt battery.

For the owner reporting six batteries, the unresolved facts are consequential: the available account does not establish whether his truck received Ford’s April or September 2026 repairs, or whether one of the identified module behaviors explains every replacement. What is documented is that Ford’s first promised software solution did not close the issue for all affected vehicles, leading to a temporary parking-brake workaround and further module updates extending into September 2026.
