I think you’re thinking of Xiaomi, Louis Rossman did a video assuming they were doing Apple-style serialization but all it was doing was blocking installation of self-driving if the headlights weren’t standard. It wasn’t DRMing brake pads or preventing buying headlights from a junkyard, there was a functional reason.
That’s only because they’re designed with passivation to vent tanks and disconnect batteries to remove sources of explosion when they start to die. If that fails the tanks eventually pop from thermal cycling or the solar panels overcharge the battery until it blows up like a Russian satellite did earlier this year.
