I think that some Hyundis are made in the US now. Even if not, I won't leave Hyundai unless something changed dramatically. They filled the gap when there were no good options for a small US car that was well built, reasonably priced, and a good car on the road.
I did have to switch dealers once. The one I switched from had a maintenance department that couldn't resist the shennanigans to increase their profits.
You don’t fix what isn’t broken...
The Koreans brought value and reliability, something sorely lacking in the US Market since the Japanese brands became premium brands... they used to make abject crap, (hyundai excel anyone?) but they made a concerted effort to build a quality product and brand... Kia/Hyundai are now mainstays in the value minded consumer (Kia in particular by offering as standard what most others sold as options).
