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 li…
If the origins are so fuzzy, I guess other manufacturers would very soon adjust their part lists/part origins to avoid the tariff?
I was involved in similar efforts to remove Chinese parts from the supply chain during the previous Trump administration. It was a nightmare that involved dozens of people reviewing tens of thousands of parts across hundreds of components with multiple revisions. I was involved for two years and that wasn't even the entire thing. Most changes required multiple layers of analysis/engineering review, change proposals (which often had to pass change review boards), vendor negotiations, manufacturer negotiations, reams of documentation about changes to refit procedures for previously produced HW, testing, validation, etc.
Removing Mexico and Canada from supply chains would be even worse. Probably nigh-impossible for some OEMs.
