The cost of those remaining maintenance items are the issue. That said, it's a reasonable hypothesis to say that this is an economies of scale issue.
(Also, as I understand it, tires are used up more quickly on EVs still, but tire companies are learning to adapt to EVs so that may not be as true today.)
It's excellent and cheap (at least it is now after thousands of customers have been used as guinea pigs and sold cars with wildly defective underpinnings) but it does mean that virtually any damage to the casting will total the car since it's not practical to replace or repair it.
Given that the majority of EVs on the road in the US are one of those two models, it really does spike average EV repair costs.
1. If you count drive gearing, it has a transmission. Teeth will experience wear if not properly maintained.
2. Almost all modern EVs now are oil cooled. There are a few exceptions. See above.
3. All have a radiator for cooling. See above.
4. The 'exhaust system' is 100% gone. Heat the only waste product.
5. There is plenty of rubber and plastic hoses and gaskets in EVs that will break during the lifetime of the vehicle, just like they do in ICE.
I totally agree that the service is much less of a burden to the owner. About an order of magnitude less 'work' for them.
Its damage repair where the problems start. Labor is expensive in US, skilled labor (electricians, welding aluminum, panel beating) double so.
I paid like €120 for it.
Not sure where your "ev services are expensive" rhetoric comes from.
100+ years ago, Electric Vehicles back the were correctly touted as having far less maintenance that fossil fuel vehicles.
Here is the thing, Items EVs do not have/need:
1. No Transmission
2. Oil Changes
3. No radiator
4. No exhaust or catalytic converter.
5. There are other things not in EVs that need regular maintenance.
So to me, maintenance should be much less for EVs, 100+ years ago the only drawback was range, and that has been solved with modern EVs.
