Kia and Hyundai released a software update on Monday after a viral TikTok challenge taught users how to hack the vehicles. But for now, it’s only available to a selected one million vehicles, out of the four million cars that will eventually need the patch.
It started as the “Kia Challenge” dating back to at least May on TikTok, demonstrating how “Kia Boys” use USB cords to hot-wire cars. Owners soon caught on to the widespread theft and began suing the car manufacturers for a lack of response. The class action lawsuit said that certain models of Kia and Hyundai cars lacked engine immobilizers, a common device that prevents car theft, making it easy to gain access, TechCrunch reported last September.
