The huge repair bills are in big part due to the fact that there are no spare parts.

Every part that can be manufactured is put into a new car and sold, there is very little surplus of parts. And what little is sold, is sold at a premium. Add a nonexistent 3rd party market to that and you've got a supply issue.

For my ICE car I could just go buy a generic part if I didn't care about the quality - and in some cases a cheaper part made for another brand (Skoda) that was 1:1 with the more expensive part (VW branded).

What doesn't break is the electric engine, there is one moving part, the shaft and excluding some outliers the engine will outlast the body of the vehicle many times over. Same with batteries, barring manufacturing issues or damage, the wear is very predictable and gradual.

This is what gives the (illusion of) reliability to EVs. There are very few mechanical parts that can just suddenly break and leave you stranded. Software and electronics though... =)
