Teslas are dead simple, to the point where people are putting Tesla anything in virtually anything you can think of - classic cars, random sedans, you name it.
There’s also that guy on YouTube who updated the electricals in his original Model S with electricals from a 10 years later Model 3 Highland just by buying spare parts, and it was pretty doable with fairly basic and limited tools/public information.
So the complexity in this article is just a BMW/PHEV thing, not an EV thing.
As they point out, the Tesla pyro fuse (at least on a Model S) is a cheap part. However, in some model years it's on top of the pack, which means you have to drop the pack to get to it. And, from memory, it's a 10 year lifespan part. However, on other Model S cars, it's easily accessible from the bottom.
I wonder how we can make automakers make more repairable cars. Obviously, right-to-repair and allowing access to documentation and tools for independent shops is a a necessary but not sufficient step.
I shudder to think at some of the other possibilities -- heavy-handed attempts to regulate how much specific repairs can cost.
Maybe mandating the sale of manufacturer-provided extended warranties for no more than x% the cost of the vehicle purchase price would be an incentive to keep repair cost in check?
