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]

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.^[4][5][6]
