I have a 2018 Cadenza with the cooled seats in the front. When I turn either of them on, they are pretty loud. I admit they cool pretty well but both seats make an audible hissing noise. When I had my 2014 this was not an issue. Anyone else have a 2018 that hears the same noise.
I've never heard of that, but I have a '14. If you have an oil change coming up soon I'd let them know about it. If not and it annoys you, call your dealer and talk to the techs, they may be able to tell you something or ask for you to bring it in. I can't hear my blowers for my seat (only driver in my car) when it's on.
