Motor oil isn't used in lubricating axle bearings or the gearbox. Those latter two are, in modern cars anyway, lubricated for "life". If Teslas, again no idea if that's the case, failed to design those components to not require regular maintenance, and then fails to define proper service intervalls, it is purely on Tesla and not the fact that we talk about EVs. Because EVs from brands with a dense service network (which is a significant revebue driver, no idea how a company can miss that) performba lot better than Tesla in the TÜV report.

I don't believe there is a modern gearbox where the manufacturer of said gearbox says it never needs oil changes. The vehicle manufacturer might say that, but not the gearbox manufacturer.

Case in point - my 2021 Wrangler has a ZF 8 speed auto that Jeep says never needs an oil change. ZF says it needs an oil and filter change every 100,00km.

"Life" is open for discussion and definition. Going with ZF, the 8 speed is a great gearbox, saves the gearbox. Going with Jeep gets you a warranty replacement.

By the way, it is still possible Jeep modified the gearbox in some way, most OEMs do.
