Ford is again recalling 2021-2022 Mustang Mach-E electric vehicles because of an issue with a key propulsion-system component that could cause loss of drive power.
The core issue is that battery main contractors can overheat after DC fast charging or when the driver floors it too many times in a row. That can lead to “arcing and deformation of the electrical contact surfaces, which can result in a contractor that remains open or a contractor that welds closed,” according to the NHTSA.

The same issue led Ford to halt Mach-E deliveries in Jun. 2022. Under that campaign, Ford delivered an over-the-air fix containing revised software for two control modules. It then issued a second recall that involved physical replacement of some electrical components in a Mach-E vehicles with the extended-range battery pack.
This third recall covers a small subset of vehicles—234—that did not receive the correct software remedy under the first recall. Ford told the NHTSA that, although successful installation was recorded, the correct software may not in fact have been install on these vehicles. Ford added that it’s unaware of any crashes or injuries related to these vehicles remaining in circulation without the software fix.

In previous recalls, Ford said contractor failure can lead either to a situation in which the vehicle will not start after it’s cycled off, or to one in which the vehicle will display “Stop Safely Now” and will cost to a stop—although power brakes, steering, and accessories will remain functional.
Owners will have to take their cars for dealerships to have the correct software installed, free of charge. Ford plans to mail owner notification letters Apr. 14. Owners can also call Ford’s customer service department at 1-866-436-7332 for more information. Ford’s reference number for this recall is 25S14.
