Ford has initiated a recall for 86 Mustang Mach-E vehicles produced between 2023 and 2025. The issue specifically affects cars equipped with lithium iron phosphate batteries that have undergone a replacement of the Battery Energy Control Module.
The replacement modules incorrectly initialize the battery health at 100 percent. This error leads the vehicle to display an inaccurate state of charge, which may result in unexpected power limitations or a complete loss of motive power while driving.
The manufacturer warns that the incorrect health calculation could increase lithium plating during DC fast-charging cycles. This process carries a potential risk of thermal venting and vehicle fires, although no such incidents have been reported to date.
Ford has confirmed that there are no known crashes or injuries associated with this software defect. The company plans to resolve the issue through a software update that will enable the control module to correctly identify the actual state of the battery.
