A Tesla representative, in a statement to the Globe, said “there are significant safety concerns when salvaged Teslas are repaired improperly or when Tesla parts are used outside of their original design intent, as these vehicles could pose a danger to both the mechanic and other drivers on the road.”
It seems Tesla is deliberately ignoring or trying to squash the aftermarket/custom-car culture which has basically existed since cars existed... and in contrast, Chrysler/Ford/GM are happy to sell you parts like engines and transmissions without caring whether they'll even be used in a car, and have been doing so for literally decades, so obviously they're aware of and not worried about any legal liability issues.
