2 known faults with sources

Engines: Mach-E (Electric)

Applies if: Built up to May 2022.

Main battery contactor on the Mustang Mach-EHigh-voltage battery

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.

Engines: Mach-E (Electric)

Applies if: US bulletin SSM 55080 for the 2021–2023 Mustang Mach-E built up to 25/6/2023; in Europe, ask the dealer.

Stops charging on DC fast chargers because of the charging module software (Mach-E and E-Transit)Electrical charging

Engine / equipment: Ford Mustang Mach-E and E-Transit electric
Period mentioned: Mach-E 2021–2023 built up to 25/6/2023 and E-Transit 2022–2025 (US model years)
Symptoms: Charging stops on DC fast chargers; it still charges on level 1 or level 2 AC chargers.
Possible cause described: The charging module (SOBDM) software stores codes P0EEE:27 or P2E53:27 and cuts charging. Ford says replacing the charge port does not fix it and is preparing a software fix (SSM 55080).
Check for the garage: Charge on AC in the meantime and ask the garage to check whether new SOBDM software is available before replacing the charge port.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.
