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 VW e-up! / Škoda Citigo e iV / Seat Mii electric reliable?

The up! electric drivetrain has few documented faults: the only significant one is a January 2021 recall over damaged cells that affected 213 cars worldwide. The data is scarce because few units were sold.[4][5]
