I have a 2020. It doesn't seem to have an axle issue. I had heard about it. But I'm assuming whatever the problem was has been corrected. I worked for Hyundai-Kia, in design. And was located at their Montgomery plant, as well as their West Point, GA Kia plant.
I saw the shenanigans that was going on there. I went to Korea many times. The shenanigans was not limited to the U.S. plants.
I worked for Hyundai-Kia after working for Toyota. People don't believe me, but compared to Toyota, Hyundai-Kia was a laughable friggin joke.
And yet Hyundai-Kia was better than nearly every European car made. People poo-poo American made cars, but for real, crap comes out of Europe. I'd have a Porsche, or any of the exotics. But I would never own a BMW, Mercedes, Audi, VW, Maserati. Well, maybe a Maserati, but would have to have plenty o' money ready for repairs.
