Hyundai and Kia offer free steering wheel locks to combat TikTok car theft challenge.

Hyundai and Kia will roll out software updates and vehicle locks on 4 million cars across the U.S. to combat the widespread theft of their cars, which has been encouraged by viral social media videos offering instructions on how to steal the cars with little more than a USB cable. The thefts have led to insurance companies denying coverage to some of those cars, and attorneys general from many states signing a letter to the automaker pleading for a fix. City attorneys from Cleveland, Seattle, and St. Louis have also sued Hyundai, claiming lost police time tracking the stolen cars.
