Main battery contactor on the Mustang Mach-E

Sources are not verified in real time and no entry confirms that your car is affected.

Engine / equipment: Ford Mustang Mach-E electric
Period mentioned: 2020–2022
Symptoms: Powertrain fault warning and a “Stop Safely Now” message: the car loses drive power while moving, or will not start.
Possible cause described: The high-voltage battery main contactor overheats with fast charging or repeated full-throttle acceleration: the contacts deform and stay open (loss of drive) or weld shut (no start). Ford recalled about 49,000 cars built from 27/5/2020 to 24/5/2022 (software); after further failures, NHTSA opened an investigation and another campaign replaced the high-voltage junction box.
Check for the garage: Check by VIN that both campaigns have been done; if the warning appears, stop somewhere safe.
Cost cited in the source: Free under the recall.A rough figure from the original database, not an up-to-date quote.
