FWIW, I'm into my fourth year of (Chinese-built) Model 3 ownership and it's been rock solid, the only services so far were to replace the air filter and wipers.
Besides that, EVs are just really heavy and weight wears out tires. Just a fact of life.
Rip away center tunnel carpet on rhs (lhd vehicle), remove 2 screws from below glove compartment, fold away panel, remove cap from filter compartment, remove 2 filters - put back together in reverse order.
That's literally a 20 minute job if you about know what you should be doing - a.k.a. read about the process in the free service manual of Tesla (only need an account, free) or watched a YT video...
(Also my Tesla is 74.5k miles, so nowhere near 100k)
-edit-
I was a victim of misinformation from my local EV repair shop.

The prices you are talking about are incorrect but there are 3rd party parts now.
This is less about EVs vs ICEs and more about Toyota's engineering quality vs Tesla's engineering quality, which is hovering somewhere in the vicinity of Homer Simpson's barbecue pit.
