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 3 / Model Y reliable?

The electric drivetrain of the Model 3 and Model Y has had few documented problems in Europe: ADAC puts the three-year-old Model 3 at 0.7 faults per 1,000 vehicles, and Aviloo measures battery health at around 89–90% at 150,000 km. There are only isolated cases of battery, motor and, somewhat more often, on-board charger or charging port failures.[1][4][5]
