The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the Fiat 500e reliable?
The 2020 500e's drivetrain has few declared faults in the motor, but its traction battery has been subject to two recalls over fire risk, and there are isolated complaints about AC charging. The available data is scarce: it is a recent model.[1][2]
See the 2 of the Fiat 500e faultsIs the Ford Mustang Mach-E reliable?
The Mach-E's electrical system has one documented weak point in Europe: the high-voltage battery contactors, which overheat and can cause a loss of power. Ford first fixed it with software (2022) and then by replacing the battery junction box (2023). No motor or battery faults have been published in Europe beyond that.[3][4][5]
