There are also gazillion things to fail and to be repaired. Sensors, hoses, cables, alternator, fuel lines, clutch, exhaust system. All these parts were replaced in family’s petrol cars during last years.
I doubt, that today’s Teslas will have battery problems. They have enough knowledge for volume production. Expect 2% early battery capacity degradation though.
No, an ICE has a very complex drivetrain with thousands of moving parts. Belts, transmissions, gears, fuel filter, oil seals and gaskets, batteries (ICE's need them too), spark plugs, fuel pump, fuel injector, alternator, radiator and water pump, catalytic converter, etc etc .
Brakes also wear slower on EVs since regnerative braking captures some energy.
Electric motors themselves are far more reliable and simpler than ICE motors.
The complexity as defined by parts count doesn't have much practical impact on TCO.
A quick change once the parts arrived they said. The car is still under warranty so won't cost me a dime, but if the bill they presented me with is real and not some "medical bill" shenanigans, the charger alone would be 1/8th the price of the car as new, total repair cost 1/5th...
So yeah, still some expensive parts that can break. Was quite happy with very little maintenance costs so far, but if that price was real and charger breaks after warranty is out, the whole value proposition is quite different.
I've replaced a few ICE batteries in my time. You can replace them at home in 5 minutes and they are a gazillion times cheaper than an EV battery. :)

This whole thing about ICE is FUD IMHO. Yes, complex, but on modern ICE vehicles is highly-reliable.
Also I would argue with EVs you are replacing ICE "complexity" with other complexity. For example, in EVs you now have individual motors on four wheels (i.e. potentially four points of failure), you have all the software in EVs etc. etc. etc.
I would also argue that the ICE "complexity" of what you speak is NOT where the bulk of ICE maintenance costs come from. Afterall, topping up the oil and replacing gaskets is kids work.
The bulk of ICE maintenance will ultimately be the same as EV maintenance, i.e. all the wear-and-tear parts I listed already, such as tyres.
There's many studies comparing the cost, I've never see any that put the saving as low as 10 to 15%, 50% is a more common figure.
Most manufacturers grantee their batteries , mine has a 10 year warranty.Batteries developing problems and needing to be replaces is not really a thing.
No, I have not cherry picked.
Because the remaining 1%, topping-up oil, replacing gaskets, belts etc. is simply not where the bulk of ICE maintenance costs come from. This sort of stuff can be done cheaply and easily by your local garage.
The bulk of the ICE and EV maintenance costs is the same, the stuff that gets exposed to the wear-and-tear of the elements, i.e. your tyres, your windscreen, your shock-absorbers etc. etc.
An EV does not make you immune to getting nails in your tyres, chips in your windscreen, cracks in your shock-absorbers etc. ....
> Most manufacturers grantee their batteries , mine has a 10 year warranty
As with most things of this nature, I would be interested to see the wordings of such warranties, particularly the exclusion clauses. :)
> There's many studies comparing the cost...
And if we exclude studies funded/conducted by the EV companies or others with vested interests ? :)
i've heard, not 100% sure if true, that EV tends to push the tyres harder, as they accelerate harder. This means tyres lasts for less for an EV.
I would think the regen breaking might also put wear on the tyres, especially for those people who like it set in the more aggressive modes.
A ten year battery warranty means most used car buyers would be without a battery warranty. My current car was 12 years old when I got it, and in basically pristine condition. Good ICE cars are very durable in a way that the batteries in EVs simply aren't.
Aren't brakes one shared system where electric vehicles have an advantage? With the widespread use of regenerative braking, most of the energy of motion is bled off without friction on wear parts. EVs still need brake discs and calipers to maintain a full stop (particularly on an incline), for emergency braking, and as a failsafe, but the parts should experience much less routine wear.
Additionally, your list omits the entire exhaust system, which is full of components that can foul up or corrode. Combustion exhaust gasses can be pretty corrosive stuff, particularly when combined with water condensation on short trips/cold days.
I'm sure you could generate a maintenance figure for EV that was lower than ICE if you wanted to. But I doubt that figure would be significant, maybe 10-15% if you're lucky.
Why ? Well, let's face it, an EV is still a car. So you still have 99% of the same old things ... tyres, brakes, shock-absorbers, windscreen, windscreen wiper blades, washer fluid, AC gas etc. etc. etc.
And then, of course, if there are problems with your EV battery, or its time for an EV battery replacement, then that 10-15% saving goes out the window. :)
