I see your point, but I'd be much more willing to try to work on an EV myself than a ICE vehicle. So many fewer parts and with the computer diagnostics it seems like replacing a drive motor or something would be a lot simpler than replacing the engine.

There are some companies that make aftermarket replacement controllers for motors and stuff, although they are generally performance oriented.

I hope in time more 3rd party repair options open up, due to sheer tenacity or competent right to repair legislation.
