I'm not sure even Tesla unambiguously qualifies here. Looking at the NHTSA part 583 list for 2025 [0], none of the Tesla vehicles have a "US" content higher than 75% (which I think includes Canada?). The highest is the base Kia EV6 at 80%. This seems to be coming from the Kogod manufacturing index. That's a more qualitative ranking that attempts to deal with things like corporate structures rather than just origin like the NHTSA numbers.
As someone who works in the industry, "where" something comes from is an inherently fuzzy concept. Different parts of the government use radically different definitions. For example, under NAFTA "domestic" parts are usually things manufactured anywhere in North America. This was done to onshore automotive manufacturing that wasn't realistically going to come back to the US, but political leaders didn't want to stay in Asia. One result of these tariffs may actually be that more auto manufacturing moves to Asia as the advantage of North American manufacturing is lost.
