I will never consider buying a Hyundai for several decades after their inexcusable security practices led to my insurer jacking up my insurance rates just for owning a Hyundai, despite being an earlier model.
I own an Ioniq 5 and there was no such unusual change in price for insurance. maybe you should have changed your insurance company rather than your car.
The posts around this regarding Kia are right that they are under the same "group" with Hyundai having a significant ownership stake.
The uptake is both have these problems and to be extremely wary of either either until they concretely show they can be trusted again. Having worked in several different software shops my experience has been software culture and security culture are extremely hard to change. It absolutely requires major restructuring in people and often major investments in reworking of software with the right priorities.
I won't be holding my breath. The most common solution (practically the only solution I've ever seen happen) is to put bandaids on and just keep reworking the big ball of mud.
Kia and Hyundai aren't actually the same company, but they're very closely related. Hyundai group (Hyundai automotive's parent company) acquired a significant stake in Kia when they went bankrupt during the Asian financial crisis. In exchange, Kia received significant percentages of many Hyundai group companies, including automotive. They share components and designs, but they're separate companies with their own teams, factories and marketing.
Seems like Hyundai own 33% of Kia, rather than it just being a brand under the same company like Lexus/Toyota. They share some things and compete on others.
It's a lot more complicated than that. They also have some common owners, and Kia owns parts of some Hyundai subsidiaries. Chaebol's are complicated beasts.
Hyundai and Kia were two separate companies that merged in 1998. Genesis is their premium brand, their Lexus equivalent. They claim to differentiate the three brands with: Hyundai: bold, Kia: sporty, Genesis: premium. Your guess is as good as mine what the difference between bold and sporty is.
Hyundai and Kia from some recent models years were missing the engine immobilizer resulting in many thefts. Maybe you're thinking of the vulnerability on Kia's web portal.
