I understand they use different drive trains and that the entire system is built differently, but aren’t there still moving parts that should be lubricated and maintained?
Thanks in advance.

The parts *do* still need lubrication, but since they are exposed to the high temperatures and frequent temperature fluctuations of combustion the lubricants don’t break down like ICE oil does. To put it in perspective, an EV motor can get up to around 140 C with normal operations, while the temperatures in the combustion chamber of an ICE can reach around 2,500 C. Granted, the ICE as a whole doesn’t get anywhere near that high (and the chamber doesn’t maintain that temperature), but exposure to those temperatures whenever a cylinder fires is what causes engine oil to breakdown over time. Well, that and the resultant residue from the engine operation and internal combustion, itself.
Yes, over time the lubrication of EV moving parts *is* going to break down, but the vehicle itself will reach an end-of-life cycle long before that.
