Thefts of Kia and Hyundai cars have surged across the country after social media users exposed security flaws, sparking what's been termed the "Kia Challenge" where people livestream their larceny. At least 20 state attorneys in the US have urged Hyundai and Kia to enhance anti-theft measures, while New York Mayor Eric Adams has blamed social media for corrupting young people. Chicago has been particularly hard hit by vehicle theft, which took off during the pandemic and added to broader concerns over spiraling crime, including carjackings. More than 19,000 cars have been stolen in Chicago this year, double last year's figure and three times more than in 2019. Some 8,350 Kia and Hyundai vehicles were stolen in the second half of 2022 in Chicago, from just 500 in the first six months of the year, according to the city. "A citywide and nationwide crime spree around automobile theft has been unfolding right before our eyes," Johnson, who's been in power for just over 100 days, said in a statement.
