You have to check the model and engine specifics. Kia had a bad run of V4 turbos due to metal shavings in the manufacturing process. I think the electric Hyundai is on recall in South Korea because it overcharges and catches on fire. That is sort of a national scandal over there as far as I can tell which will probably lead to positive changes in their manufacturing processes. It also took a lot of hassle of those V4 Kia owners to get warranty coverage.

That being said the V6 lambda engines are very nice and considered reliable. They started with the Genesis which was an important flagship vehicle. I have a V6 and have had no issues approaching 100k. But I am the type of person that wants to get 200k out of my vehicles, I have no idea if that will happen. I'd be upset if the car failed before 10 years as well.

There are forums where you can get an idea, especially if you look at previous model years.
