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.[1][2][3]

Is the Tesla Model S / Model X reliable?

The Tesla Model S and X electric drivetrain looks sound: Auto Bild hardly records any motor or battery faults, and the documented faults are isolated. The most-cited problems with these cars fall outside this section (screen, suspension, doors).[4][5]
