Ford Halts Mustang Mach-E Sales Over Safety Issue Affecting Nearly 49,000 Cars

As legacy automakers like Ford launch their first few electric vehicles (EVs), they’re bound to have some quirks — or major issues — that need to be resolved, like one issue the company is having with its Mustang Mach-E.

Ford is asking dealers to halt delivery of the Mustang Mach-E over a propulsion malfunction that could cause the EV to lose propulsion power while in motion, according to a dealer notice on Monday shared by CNBC.

In the notice, Ford said potentially affected vehicles included those with model years 2021 and 2022, built between May 27, 2020, and May 24, 2022, at the automaker’s Cuautitlan, Mexico production facility.

The vehicles affected include around 49,000 of the 100,000 or so Mach-E units that were produced during that time, according to Ford spokesperson Said Deep.

The issue is caused by overheating of the EV’s high-voltage battery main contractors, an electrical switch that controls the power circuit.

When malfunctioning, vehicles could either not start or stop running while driving — the latter of which is especially dangerous.

Deep said the fix will come in the form of a software update to the “Secondary On-Board Diagnostic Control Module and Battery Energy Control Module,” taking place over-the-air (OTA).

In the past, Ford had to recall several of its vehicles due to concerns with the glass roof falling off.
