I have driven approximately 700k miles across five vehicles and never touched any of these, nor have I ever been concerned about them, except with the vague idea such things can become a problem around ~250-300k miles.
What I have had enormous trouble with in all ICE cars is the electronics, which if anything are more populous in EVs.
The idea that "EV maintenance is clearly superior to ICE maintenance" seems like a baffling canard to me, aside from relieving me of the very minor burden of changing my oil twice a year or so, and some even more infrequent $20 filter replacements or simple spark plug replacements I've had to do exactly once which required only a deep socket. I've done more maintenance on my desktop computer.
I’ve had a few electronics failures happen within two years of owning a car. Let’s give your EV a lot longer than two years before we pass judgement on it, though. I’ve had displays fail at 30k, that’s obviously not an ICE problem. (It was bad solder.)
None of my cars stayed with me longer than 220k, but I have never heard of anyone that wasn’t driving cars from the 70s and 80s having to do those things, or with very high mileage.
The drivetrain in an EV is WAY simpler than any ICE. That alone will provide a ton of reliability. There's pretty much just one moving part in the engine and it's pretty binary. It's either working or it's completely broken.
No more weird running issues where it works just fine to 2000rpm, but at 4000rpm makes that weird noise. Or the transmission rattles a bit at exactly 3700rpm, but is fine on other rpms.
Yes, an electric motor is conceptually simpler. Yes, there’s less moving parts. But the powertrain in modern cars is engineered to a point where it is incredibly reliable and can be expected to last to the point where the rest of the car is falling apart too.
There will be plenty of “weird running issues” from software bugs and electronics failures, which are the worst and least reliable parts in ICE cars as well. An EV is not just a simple electric motor packed into a case.
Finally, as I noted elsewhere in the thread, Tesla is offering the same powertrain warranty on Model 3s that Kia is offering on their ICE cars. Clearly Tesla doesn’t have any more faith in electric powertrains than Kia has in ICE powertrains. If the EV powertrain was really so much more reliable than ICE, Tesla would be offering a standard 250k mile warranty on the powertrain instead of the same 100k warranty offered by some ICE manufacturers.
Engine work, transmission maintenance or rebuild, replacing fuel pump, belts, alternator, etc. these are all totally standard and very common repairs for ICE vehicles no matter how many miles you say you’ve driven without having to touch them…
EV maintenance costs have been well studied at this point and are lower than ICE, and for very sensible reasons, it’s not a mystery or a canard.
There have been many many studies. Here’s a random one;
Very common? You have anything to back that up? I don’t even know anyone whose had to do any of that. I know that people do, but certainly not “commonly” unless they’re driving a very old, high mileage car they don’t want to part with.
I’ve seen lots of electronics failures. This will only be worse in EVs, or at least EVs like Teslas, where things like door handles have been motorized.
The average age of a car is ~12[0] years in Finland. Out of the 7 people I often interact with that have cars, 7 have had those, and a lot of other parts fail
Either there is something especially harsh about Finland's environment, or whatever cars they're making there are uniquely bad. That's absolutely unheard of where I live. 12 years is definitely not what I meant by "old".
Of course a sufficiently old car will be falling apart, whether it's part of the "ICE" or not - the suspension and shocks will be need to be replaced, door seals degraded or positively worthless, interior will be faded and cracking, wheel bearings fail, AC compressor goes out, various sensors fail (my favorite so far was the antitheft sensor)...when everything starts going bad, that's when I would expect the engine to be just be worn; basically, I would expect the ICE to last as long, or outlast, the rest of the car, save any issues on the left hand of the bathtub curve from manufacturing defects that should be covered under warranty. What you're saying is totally wild and alien to me. Mechanics must get a lot of business there.
If EVs are so reliable and maintenance free, why is the Tesla drivetrain warranty only 100k miles on the Model 3? That's no different than many ICE cars (eg I know Kia has the same warranty on ICE cars), and also well within the middle of the bathtub curve for an ICE car.
A thing to consider is the average means there are tons of older cars in the mix, but some new ones slowly creeping in. There are lots of cars from the 90s or even 80s driving around where I'm from. Weather can be quite unforgiving for cars here, temperature ranging from -25C(-13F) to +30C(86F) year round. Lots of salt and some types of pavement seem to be exceptionally bad for timing gears[0]. Owning a car is likely the most expensive thing a normal person can do in Finland.
I think it's fair to say, based on your own link which is about research into why timing belts are not lasting as long as everywhere else (a third to half the time!), some of this is outlier. And they note that this dust would also abnormally wear brakes, anything rotating, and the car's painted surfaces, which EVs also have.
But for the rest of it, like temperature differences...this is still going to be a major impact on EVs, and like ICE cars, it won't be just the engine you have to worry about.
As I noted upthread, Tesla has the same powertrain warranty that, say, Kia has. It isn't much of a testament to the vaunted EV reliability that the most famous EV manufacturer doesn't have more faith in their electric powertrains than Kia does in their ICE powertrains.
