That's still super low cost compared to all the regular repairs a combustion engine needs, especially when you consider that combustion cars also need tire replacements, just a bit less often
Are you driving an alfa romeo? An engine is just a part of a car that needs service and there are ICE cars with 500kkm on them that only had their oil and maybe a timing belt replaced. Neither is an expensive thing.
The electric cars also have suspension, brakes, comfort systems etc. And those need fixes or maintenance just as often if not more often then the engine (especially with more electronics and smarts these days).
The electric propulsion system also isn’t a simple thing and I bet with enough time there are going to be brands or models to avoid because of expensive battery/drive train component failures.
That being said an electric brushless motor has much less mechanical complexity than an ICE. But saying that EVs are going to require significantly less maintenance needs to wait till we see twenty year old electric cars with hundreds of thousands kilometers on the odometers.
...And emissions valves, vacuum hoses, evap canisters, fuel cap/seals, possibly a valve cover gasket, serpentine belt, tensioner, and idlers, fuel filter, possibly the fuel pump. 500,000 kilometers is 310,685 miles for all the Yanks and Brits in the audience, and if you manage to drive a combustion car that far without needing all of those things, let alone any selection of them, I will eat my distributor cap.
I've driven a diesel Renault for 12 years (loke 300k km) and didn't need to replace any of those. The only big unplanned cost I had was a faulty EGR valve, which happened at 600km and wasn't warranty for some reason.
That said regular oil change for clutch and brakes were mildly expensive, but I guess even for EV you'd want the brake hydraulics replaced the same way.
Edit : just spotted filters. Yeah I replaced every filter every service, but with how grimy they look, even in EV I'd argue for replacing them.
Funnily enough I heard mechanic friends say that EVs need the brake rotors replaced more often than combustion cars, because the EVs use the brakes so infrequently that the rotor just rusts so badly it needs replacing.
My Subaru needed head gasket twice, transmission failed, and needed a catalytic converter, among other things that don't even exist on an electric car. Maybe if ICE companies and dealerships didn't screw people over so hard, I'd consider buying one again. I'm going to try something different this time.
Dealer lied to me to get the sale in multiple ways, saying that the head gasket issue was fixed (it was, but not for the car they were selling me) and told me that the transmission fluid was not supposed to ever be changed (it was, and not changing it is probably why the transmission failed). Bunch of scammer scumbags, my next car will NOT be purchased from a dealer. If their business model requires a state law forcing them into the middle of a transaction, they're parasites.
I'd donate to Trump by buying a Tesla before I'd purchase a car from a dealership again.
