EVs or only Teslas? I have a suspicion that that is true primarily for Teslas. I have a Toyota plug-in hybrid, which theoretically is an EVs as well as an ICE car, and its repair/maintainance is similar to that of an ICE. The high cost of Tesla repair is due to their vertical integration, perhaps limited capacity devoted to spares and monopoly over who repairs (max rent selling from repair). EVs should be cheaper to repair and maintain.
