Cost-per-mile is cheaper from electricity than from diesel, and it's expected to have lower maintenance costs too (fewer moving parts, no oil changes, etc)
It's been almost four years for me, and I've had to spend exactly $0 in maintenance on my Model 3. We'll see what the future holds, but not bad so far.
It has been 3 years with my Toyota and all I have paid for is new windscreen-wipers (winter ruins them). I don't see how that matters though. What matters are actual numbers from a trusted source: ADAC (German motor organization) says it costs $0,51 per kilometer to drive a Tesla Model 3. My Toyota costs $0,31. Nothing exceptional about the price on Tesla maintenance.
You didn't link your reference, so I don't know how those numbers were calculated. However, they are so large they are clearly not maintenance costs, but probably all in costs. That's apples to oranges (Tesla vs Toyota are two different segments). It's also not the topic of conversation (Tesla maintenance costs).
ADAC's measure includes the cost of the vehicle itself so that number is completely inappropriate for the actual operating costs. Also ADAC has been called out as wrong and having biased testing many times: https://insideevs.com/news/456957/bjorn-nyland-charging-loss...
My PHEV has a two year oil change interval, I'd imagine a Toyota hybrid does too. So in 3 years of driving, there's one oil change, but they only said they didn't pay for anything other than wipers. First service paid for is a pretty common incentive with a car (may be factory included)
