Except there are less parts overall in an EV. Way way way way less parts. And way way way way less fluids for said parts.

Less parts means less things to maintenance. Less fluids means less things to refill.

In terms of "wearing out" the big questions really centers on the battery itself. We're seeing pretty low battery degradation on Teslas that have been on the road for 5+ years [1]. The data indicates that at 100k miles they lose about 5% power, which is pretty good. This is data about Teslas specifically though (they're the only car company that has enough long term data at scale to do this analysis on) and every car company has a different battery composition.

But aside from the battery (which is a BIG aside), there is a lot less parts (especially moving parts) that have to be watched/maintained/etc.
