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 Renault 5 E-Tech (AmpR Small) reliable?

2024 drivetrain with little data: Fiches-auto.fr has only 11 owner reports, and the official issues are an inverter reprogramming (0EN5, around 15,700 cars from 2024) and a campaign over defective cells in the 52 kWh battery from December 2025 to January 2026. There is no longevity data.^[4][5][6]
