4 known faults

Standard Range 269 ch

  1. Electric doors locked after 12 V battery discharge (recall)

    Manufacturer recall

    If the 12 V battery drops below about 8.4 V, the electric door handles may stay locked after the driver or front passenger exits, risking trapping an occupant (for example a child in the rear). Recall 25S65 (US campaign 25V404) covers around 197,000 Mach-Es from 2021 to 2025; Autoblog presents it as a worldwide recall. The correction is a software update at a dealership.

    Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

  2. Rear differential: risk of axle shaft failure (US recall 2026)

    Manufacturer recall

    Ford recalled 42,784 Mustang Mach-Es from 2021 to 2023 in the United States: a rear differential pinion shaft can break through fatigue, causing sudden loss of power or the vehicle moving when stationary if the parking brake is not applied. The exact cause is still under investigation, the solution is expected by the end of 2026, and sources disagree on the specific versions concerned (rear-wheel drive or all versions).

  3. 12 V battery discharged

    Severity 1/3 · Annoying

    On early Mach-Es, a software fault could discharge the 12 V battery during high-voltage charging and prevent the car from being opened or started; a software fix (reprogramming at a dealership) was offered, followed by a more recent update for Mach-Es built before June 2025, according to the FAQ of an owners' forum.

Extended Range 294 ch

  1. High-voltage battery contactors overheating (recall)

    Manufacturer recall

    In the United States, Ford recalled around 49,000 Mach-Es in 2022: the main high-voltage battery contactors can overheat during DC fast charging and repeated full-throttle acceleration, with a risk of power loss. The fix was a software update. A later recall (23S56, 2023) provides for replacing the high-voltage junction box on some 2021-2022 Extended Range versions. We have found no confirmation of an equivalent recall in France.
