Not very well to be honest.

On the topic of Hyundai dual clutches:

Generally unlike Ford, Renault, Fiat and VW - Hyundai dual clutches actually do last consistently for over 125,000 miles.

With that being said, they don’t ride well at all. I hear people that are saying that they have nasty vibrations and poor shift quality.

I probably will be soon able to get my hands on a car with Hyundai built dual clutch to use as a long term vehicle and if I’ll find anything interesting I’ll make a post 👀

On the topic of Hyundai CVT transmissions:

the current generation has been made only since 2019 so it’s really too early to have the exact precise information.

There’s this great video (in Russian, I’ll link it in the comments) of a Hyundai built CVT transmission in a Kia completely disintegrating and locking up during a review.

so far, the software is terrible - jerking and not able to protect it self from a bad driver and very easy to burn out.

Basically, if I had to pick between an old Nissan and a new Hyundai/Kia CVT id get a Nissan - cause at least technicians already know how to repair them when on the Kia no one yet knows.

Conventional automatic transmissions:

Hyundai is the only manufacturer (besides Citroën petrol engines and Jatco transmissions) I know that rates it’s products to last bellow 120,000 miles (in the case of the accent it’s rated to go just a bit over 110k miles)

The rest are reasonable but at least in the hands of a good tech, they’re simple and cheap to rebuild (- unlike so many others ZF 9ZF, AISIN TG-81SC (,…) that don’t last long and are not easy to rebuilt at all)

with Hyundai, you gotta research what tranny you’re going to get and go by that. They do vary a lot form model to model - But that’s most companies (including the Japanese) nowadays.

Junk. And junk. 

Everything that Hyundai (including Kia and Genesis) has made is garbage.
