Unfortunately, Tesla is starting to build their battery packs in-frame so it'll become harder to repair. https://electrek.co/2021/01/19/tesla-structural-battery-pack...
A real shame since electric cars are extremely simple. There’s not a panoply of different parts that slowly wear out and need to be troubleshooted separately and replaced at different times. It’s basically the battery pack and brakes.
All of these can suffer failure and require replacing. Even if they are unlikely to wear out in normal circumstances, people get into fender benders, and there are always exceptional circumstances. Given the huge number of parts and miles of wiring, the average owner can expect exceptional failures on a few parts. All modern cars are extremely complex, even if the drivetrain is simplified.
