Is the Hyundai-Kia E-GMP (Ioniq 5, Ioniq 6, EV6) reliable?

The E-GMP platform is reasonably reliable, with one clear caveat: the ICCU (on-board charger and 12 V converter) had campaigns on the Ioniq 5, Ioniq 6 and EV6 up to production in early 2024. Beyond that, the battery keeps high health in measurements and the motor has few documented cases.[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]
