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.[1][2][3]
