The simple way to protect consumers ability to fix products is to simply require manufacturers to provide the information to do it.
But, I still don't think this is an IP law issue. IP law should not be a weapon used to prevent you from repairing your devices -- but neither should anything else. If you only change IP law, companies are just going to find a different way to prevent you from mucking with their stuff.
There's a reason we call this "right to repair" and not "right to make an attempt to do hacky DRM workarounds"
The current discussion is about fixing cars. But the right to repair is a problem for everything with a computer in it.
You could take the title of this article and replace "an electric vehicle" just about any electronic device most people would own.
