In a recent written notice, Ford Motor Company told dealers to temporarily stop selling electric Mustang Mach-E crossovers because a potential safety defect could cause the vehicles to become immobile, reports CNBC.

The 48,924 affected vehicles include 2021 and 2022 Mach-Es that were built from May 27, 2020, through May 24, 2022, at the automaker's Cuautitlan plant in Mexico, according to multiple reports.

The next step is a safety recall that will impact approximately 49,000 vehicles. The National Highway Traffic Safety Administration told Automotive Fleet that they “received the recall filing from Ford, and it will be posted soon.”

The problem involves a potential overheating of the vehicle's DC fast-charging high-voltage battery main contactors, which is an electrically controlled switch for a power circuit. This scenario can result in a malfunction that could cause the vehicle to fail to start or immediately lose propulsion power while in motion, according to Ford’s dealer notice.

In a since posted FAQ, Ford said the vehicles can still be purchased from a dealer, but will be held until it receives the OTA software update, which is expected in July. Those with the vehicle already can continue driving it.

Owners will be notified via mail after repair instructions and parts ordering information have been provided to dealers.

The remedy for the problem will be a Secondary On-Board Diagnostic Control Module (SOBDMC) and Battery Energy Control Module (BECM) software update. As an alternative, owners may choose to take their vehicle to a Ford or Lincoln dealer to complete the software update.
