2021—2022 Ford Mustang Mach-E® — Overheating Battery System Recall

Direct Current (“DC”) fast charging and repeated wide-open-pedal events can cause the high-voltage battery main contactors to overheat on certain extended-range and GT models. Overheating may lead to deformation of the electrical contact surfaces, which can result in a contactor that is prevented from properly closing or a contactor that welds closed. An overheated contactor that is prevented from properly closing while driving can result in a loss of motive power.

The high-voltage battery main contactor is not robust to heat generated by multiple DC fast-charge and wide-open-pedal events. A prior software update improved monitoring and management of the main contactor. Damage to the extended-range and GT contactors caused by wear prior to the software update may reduce the effectiveness of the software.

Your Ford Dealer will replace the High Voltage Battery Junction Box.

Certain 2021–2022 model-year Mustang Mach-E^® extended-range and GTs built between May 27, 2020 to May 24, 2022.

Rental vehicles are available for your personal transportation at no charge (except for fuel and insurance) while your vehicle is at the dealership for repairs. Complimentary vehicle Pick-Up & Delivery service may also be available upon request through participating dealers.

Ford is not aware of any reports of accident or injury related to this condition.

We ask that affected customers limit repeated back-to-back wide open pedal accelerations and use DC fast Charging only when necessary.

For vehicles that previously received the software update, in most cases, the software will proactively detect damage to the contactors and display a warning wrench light. If the contactors weld closed while driving, there will be no immediate effect on vehicle operation. Upon the next key cycle, a wrench light will be illuminated, and the vehicle will not start. If the contactors are prevented from properly closing while driving, a wrench light will be illuminated, the vehicle will display “Stop Safely Now,” and the vehicle will immediately lose motive power. The vehicle will coast to a stop, and all low-voltage systems, including power brakes, steering, and lights, will remain functional.
