To be fair there's not a lot of data on any EV brand. Just like job postings, you can't really ask for 20 years of road experience from something that has only been on the road for 10.

I've heard both good and bad about the service on Chinese brands. It depends on where you are in the world. Apparently they prioritize some markets over others when it comes to spare parts. I think they're currently strung out from the rapid expansion, choking on their success.

Since all other brands are also dependent on the production in China, it's really only up to them which brands they'll support in the future.

On the positive side, the maintenance and repairs don't seem to be as specific to the brands as previous car makes. They're using no-name mechanic shops instead of running their own. They can do this because EVs are fairly simple. The mechanics only need to know how to exchange the broken part with a new one instead of actually fixing some wildly complicated thing in a conventional engine. Plug and Play really. I wouldn't say that I like that approach, but I can't deny that it's both more efficient and apparently also cheaper.

The same thing is happening to modern ICE cars as well. Labor is more expensive than chinese car parts. You can probably order them straight off temu. I hate it, but that's the future.
