From what I know all of this originated in Milwaukee with the original "Kia Boyz"[0]. It's been going on there for years - to the point where I've seen wedding invitations that explicitly state not to bring a Kia/Hyundai to Milwaukee. Additionally, car rental companies will not rent Kia/Hyundai anywhere near Milwaukee.
As is the case with most car thefts they are an absolute menace to the streets. "Drive it like it's stolen" is a very real thing[1][2].
Warning - discussion on this topic gets especially racist very quickly so as usual ignore the comments. Seriously, don't even look.
