Companies feel the need to not just earn money when they sell their product, but earn to even more over its whole lifetime. This refocuses their goal into providing products that regularly need some attention, which only they can provide, instead of creating the best product they can before it is sold, and let the customer and third-parties maintain it if necessary.
Then there's issues like that one with early versions of the Model S that had a flash chip that wore out prematurely. Tesla's "put everything on one big motherboard" approach is good for reliability and manufacturing because there aren't any connectors to deal with, but it (generally) means you have to replace the whole thing if something breaks.
The upcoming Dacia Spring EV is a perfect counter-example.
