Is the Renault-Nissan CMF-EV (Mégane E-Tech, Ariya) reliable?

The CMF-EV platform has a short track record and little data: on the Nissan Ariya, the documented problems are two recalls of the traction motor (metal shavings on the slip rings and an oil leak from the seal), both on 2022 and 2023 units. On the Mégane E-Tech there are only owner reports, mostly about charging, and a 2025 campaign concerning a connector in the battery cooling circuit.[1][2][3][4]

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.[5][6]
