Tesla’s overall score of 40 still puts it above the average EV score of 34. The most frequent problems among electric vehicles usually have to do with their battery pack, charging system and drive motors.
The low score of 34 makes EVs on average noticeably less reliable overall than hybrids, according to CR’s data. They don’t go too in-depth in the issue, though, simply stating that “as more EVs hit the marketplace and automakers build each model in greater numbers, we are seeing that some of them have problems with the battery packs, charging systems, and the motors in their drive systems. Owners of the Chevrolet Bolt, Ford Mustang Mach-E, Hyundai Kona Electric, and Volkswagen ID.4 all reported some of these issues.”
