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.[1][2][3]

Is the Stellantis e-CMP (e-208, Corsa-e, ë-C4…) reliable?

Stellantis’s electric drivetrain has no serious factory faults documented: the battery holds up well (median 94% health at 50,000 km and 90.7% at 150,000 km in the e-208 and Corsa-e), and the problems cited are the charger and several software campaigns.[4][5][6]
