Mazda specifically decided to no longer export to Canada because Canada set retaliatory tariffs. They still manufacture here in the US, they just won't ship CX-50 vehicles to Canada. (I think that was temporary too).
Stellantis (Jeep, et al that you mentioned) temporarily paused some plants in Mexico and Canada because the Tariffs on parts being shipped in to them from the US (yes, again because of the retaliatory tariffs set by Canada/Mexico).
Jaguar Land Rover waited a bit to import here in order to assess the tariff impact, but they started back up again.
Audi (again to the US, not from, they didn't close plants here) chose to pause imports as well, but they are currently shipping them to the US... They chose not to open a plant here.
Now Volvo noticed a lag in the Sedan market and they contemplated increasing US production and cancelling the S90 (built in China), but simply didn't do either. However, this wasn't due to tariffs, it was due to lower demand for the product.
Hyundai ramped up US Production, Toyota kept their prices level and absorbed some of the cost...
