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

Electronic key fob for a Ford vehicle

Recall Reference Number: 23S56

The safety of everyone in your vehicle is something we take seriously. That is why we are issuing a safety recall for some 2021–2022 model-year Mustang Mach-E® extended-range and GT models built between May 27, 2020, and May 24, 2022.

A key component of the vehicle's battery system may not be able to stand up to heat generated from multiple DC fast-charge and wide open pedal events. This could mean that your vehicle could be prevented from starting or lose motive power while driving.

In an earlier safety recall, 22S41, new software was updated to monitor contactor temperature, reduce battery power to prevent further damage and alert owners of any damage. However, preexisting damage to components before the software was updated may reduce the software's effectiveness.

You can see if your vehicle is included in this safety recall by entering your VIN aquí.

To have your High Voltage Battery Junction Box replaced, you can book your appointment in the FordPass® App, online, or by contacting your local Concesionario Ford.

Thank you for being a Ford Owner.


Preguntas Frecuentes

What is the issue tied to this safety 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.

What is the cause of the issue?

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.

¿Cuál es la reparación que se espera?

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

Which vehicles are affected?

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

What are you doing to take care of customers?

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.

Is Ford aware of any accidents or injuries resulting from this condition?

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

Is there anything a customer can do to reduce the chance of the contactor overheating until their vehicle is repaired?

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

Is there a warning sign that customers should be aware of?

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.

When will you notify customers of the safety recall?

Ford sent letters to customers on November 6, 2023. Customers can also verify if their vehicle is included by entering their VIN at www.ford.com/support/recalls/.

Will there be a charge to customers?

Customers will not be charged for service.

What is the Ford reference number for this safety recall?
