Funny how that's brought up when people talk BEVs vs ICE.
Some BEVs have transmissions. So some of them do need serviced.
All BEVs do have differentials- which are required because cars go around corners and don't run with locked and fixed axles. The only real way around that is to have a motor for each wheel- and that's not exactly the cheap version.
And I don't know about you, but even a $100 oil change is pretty minor vs. gas. But you can find them for half that at dealers. Or free for a few years on new cars.
There IS lubrication systems for BEVs, since stuff spins, as there is a cooling system for BEVs. Those, too will need maintained.
At some point, the battery will drop off enough that the rage will be an issue, too.
I get the allure for BEVs. And know a lot of people who worship at the feet of Musk because of Tesla. But one can't ignore all of the issues. If there were not any, we'd all be driving BEVs right now. Auto companies have no reason to keep ICE vs. BEVs other than the issues, as they don't actually get paid off by the oil companies.
