I mean the core feature here is a vastly simplified drivetrain and often modular parts borrowed or 'appropriated' from the best of existing marques. There's a lot less to go wrong versus any existing ICE platform, and the Chinese EVs that make the Western market are generally the budget/barebones models outside of the the high-end BYD stuff.
In comparison, the last two generations of ICE cars from Europe/US are the most mechanically complex in history in order to meet strict emissions laws.
The main point of contention is around support for the integrated cloud connectivity and continuous OTA software updates. Ultimately that will be clean-room decompiled or otherwise audited for PII/Security Compliance to the point where reverse-engineering for LTS is trivial.
Other than that, just as displayed with walled-garden Apple products, a robust, decentralized aftermarket will emerge from the legions of SEA hackers.
