This is sadly already happening. In Europe, car garages need to update their diagnosis machines, or even pay[1], to get some keys from Renault to being able to do anything in their newer models. Even their low-cost subbranch Dacia need those keys. They say they do that to prevent attacks from the OBD port (used commonly to steal cars). This not only is absolutely an anti-consumer practice, but also is probably a pretty temporal and ineffective solution to prevent your car being stolen[2]. Nowadays, is pretty common to need to program some kind of electronic module in the car for some parts replacements, and with that, they are preventing people and small and new car garages to do that kind of repairs. Heck, even the TPMS control module need to "re-learn" "where is who" when you rotate your tyres. [1]: Usually diagnosis machines have a subscription-based system where they provide you not only new car models software packages, but also instructions about how to do part replacements. [2]: AFAIK, most stolen cars are really easy to stole (like the 80s/90s Honda's) or really valuable (and they provide tools, ECMs, or whatever they need to stole them).
