Ford has issued a recall for 234 Mustang Mach-E electric SUVs from the 2021-2022 model years in the United States after discovering that some vehicles did not receive a necessary software update, despite being marked as repaired. The update was originally intended to address a potential risk of power loss due to an overheating battery contactor, the company said.
The recall relates to Ford’s 2022 Safety Recall 22S41 (NHTSA recall number 24V-412), which sought to fix a defect in the high-voltage battery main contactors. Under heavy acceleration or DC fast charging, these components could overheat, potentially causing them to weld shut or remain open, leading to a sudden loss of power while driving.

Ford said a flaw in the dealer service tool responsible for applying the software update resulted in some vehicles receiving an incorrect software version. “Ford has now identified that some vehicles were mistakenly marked as having received the necessary software update when, in fact, they did not,” the automaker said.
The issue was first identified in November 2024 when a quality audit flagged discrepancies in the software versions applied to vehicles that had undergone recall repairs. Further investigation found that while 98.6% of the affected vehicles received the update correctly, a small number still required the proper fix.

Owners of the affected Mustang Mach-E vehicles will need to visit their dealership for a free software update. Ford has also introduced additional verification steps to ensure future recall repairs are completed accurately. “To prevent future errors, Ford has implemented a verification step requiring technicians to validate the software part numbers before closing the recall case,” the company said.
