Is the Ford Mustang Mach-E reliable?

The Mach-E's electrical system has one documented weak point in Europe: the high-voltage battery contactors, which overheat and can cause a loss of power. Ford first fixed it with software (2022) and then by replacing the battery junction box (2023). No motor or battery faults have been published in Europe beyond that.[1][2][3]

Is the Mazda MX-30 e-Skyactiv reliable?

The MX-30 e-Skyactiv's electric powertrain has no faults of its own documented: the two European campaigns for the drivetrain (Motor Hill Assist on 2020 cars and the on-board charger on 2022–2023 cars) are corrected with software. We have found no battery degradation or motor faults in the sources consulted.[4][5][6]
