If you do manage to get the car back, you find yourself much more interested in car anti-theft measures, and will then discover that there are very limited options for parts due to the epidemic of them being stolen (66% of cars stolen in 2021 in Milwaukee, the center of the epidemic were Kia/Hyundai). And there is no indication that the company will be of any help going forward. The only real option is to not buy pre-2021 Hyundais/Kias.
