Ford has recalled a very small number of Mustang Mach-E electric SUVs after discovering that a replacement battery control module can incorrectly report the health of the vehicle’s high-voltage battery.
The recall covers just 86 Mustang Mach-E vehicles from the 2023–2025 model years. The affected vehicles have LFP batteries and previously received a replacement Battery Energy Control Module (BECM) during a repair.

According to the recall information, the replacement module can incorrectly assume that the battery has 100% of its original health instead of accurately recognizing the condition of the battery already installed in the vehicle.
That may sound like a software error that only affects the number shown on the dashboard, but Ford says the consequences can be considerably more serious.

What Is Wrong With the Mustang Mach-E Battery System?
The BECM is responsible for monitoring and managing important information related to the Mustang Mach-E’s high-voltage battery.
In the affected vehicles, a replacement BECM can default the battery’s State of Health to 100%, rather than learning the actual condition of the battery pack. As a result, the vehicle can also display an incorrect State of Charge to the driver.
In simple terms, the Mustang Mach-E could potentially tell its driver that more usable battery energy remains than is actually available.
Ford’s earlier technical service information also identified an overestimated battery State of Health following a BECM replacement on certain Mach-E vehicles with LFP standard-range batteries.
Unexpected Power Loss Is One of the Risks
An incorrect battery State of Charge reading can become a safety issue if the vehicle believes it has more available energy than it actually does.
Ford says the condition can lead to unexpected power limitation and eventual loss of motive power, which can increase the risk of a crash.
Drivers may therefore experience a situation where the vehicle begins limiting available power even though the battery percentage shown on the instrument cluster suggests that there should still be sufficient charge.
Ford Also Warns About Potential Battery Fire Risk
There is another concern associated with the problem.
Ford says the incorrect battery State of Health calculation can increase the risk associated with repeated DC fast-charging cycles. NHTSA’s recall information specifically identifies an increased risk of a high-voltage battery fire as one of the potential consequences.
However, Ford said it was not aware of any crashes, injuries or fires related to this specific condition when the recall was filed.
Only 86 Mustang Mach-E SUVs Are Included
Unlike many large automotive recalls, this campaign affects a very small number of vehicles.
Ford estimates that 86 vehicles are potentially affected. The recall applies to certain 2023, 2024 and 2025 Mustang Mach-E vehicles that received a replacement BECM during an earlier repair.
The affected vehicles were produced between July 3, 2023 and August 26, 2025. However, owners should not assume that every Mach-E from these model years is affected because recalls apply to specific vehicles identified by their VINs.

How Will Ford Fix the Problem?
The good news for affected owners is that the remedy is software-related.
Ford dealers will update the BECM software free of charge so that the module can correctly recognize the actual condition of the battery.
The recall is listed under NHTSA campaign 26V582000 and Ford’s internal recall number 26S68. VINs involved in the campaign became searchable through NHTSA beginning September 9, 2026.
NHTSA’s current recall information says interim owner notification letters are expected around October 26, 2026, while the final remedy is anticipated to become available in December 2026.
Why This Recall Is Interesting for EV Owners
This recall highlights how heavily modern EVs depend on software to accurately understand what is happening inside the battery pack.
A battery percentage displayed on the dashboard is not simply a direct measurement of remaining energy. The vehicle’s control systems continuously calculate battery condition and available charge.
In this case, a replacement control module incorrectly estimating battery health can potentially affect what the driver sees and how the vehicle manages its available power.
For the 86 affected Mustang Mach-E owners, Ford’s software update is designed to correct that calculation before the problem leads to a more serious situation.
Auto India Daily Verdict
This is a small recall by volume, but it is an interesting example of how a post-repair software issue can create a new problem in an EV’s battery management system.
Ford’s recall specifically affects 86 select 2023–2025 Mustang Mach-E vehicles that received replacement BECMs. The company says the incorrect battery calculation can result in an inaccurate charge reading, unexpected power loss and an increased fire risk after repeated DC fast charging.
