Ah, that bulletin is global, not just China. The early Fore and Mid lower control arms had a weak casting that can break randomly. Those parts are available from aftermarket providers for like 1/3 the price of a Tesla unit....You should be able to redo the entire front for less than $1k. For the rear, you need rear lower control arms, also available aftermarket.
The strut assembly is not included in that bulletin, though. You don't need to replace those unless you just want to.
