A lot of TikTok posters made videos showing how to break into Hyundais and Kias as they lack immobilizers, so anyone looking for a car to joyride in or use as a getaway car during a robbery or a driveby could just steal one instead. You find a lot of abandoned Kias and Hyundais down in Hunter's Point in SF for that reason.
Hyundai and Kia cheaped out by not including a couple dollar part that makes it harder to hotwire. Apparently kids can hotwire them with a USB cable because they don't have the immobilizer. It affects several years worth of Kia and Hyundai models.
