"Now they come with software and a prohibition against customer modification or repair."
This is not entirely unreasonable, they can probably justify it some way, of course it's probably just a away go guarantee their service contracts.

If your modification or repair can be shown to contribute to a problem/ accident, you're held liable, not the manufacturer.
Instead it was used, and abused by manufacturers - "Oh, your transmission blew? Horrible! It's a real shame that you put aftermarket rims on your car, those are non approved parts and void your vehicles warranty!"
Think about it: some guy changes the suspension on his car, making it super tight, puts racing wheels on - and then claims an issue on 'warranty' when something happens due to his modifications?
It's definitely within reason to forfeit a warranty if someone hacks up the product with their customizations.
There's no way an auto-manufacturer can provide warranties for parts, which depend on other parts - that have been altered.
