Ford said it was recalling about 49,000 Mustang Mach-E electric vehicles in the United States because of the potential for heat that could result in loss of propulsion.
The electric vehicles affected are the 2021 and 2022 Mach-Es built from May 27, 2020, to May 24, 2022, at the automaker's Cuautitlan plant in Mexico. Ford itself said the issue was addressed in a software update that is expected to begin next month.
The potential for overheating comes from the main contactor of the vehicle's high-voltage battery, which is an electrically controlled switch for the power circuit. The heat can result in loss of propulsion, increasing the risk of an accident.
Ford said it had contacted dealers not to ship new vehicles to customers until they had a software update.
