Just experienced the same problem described in this thread and its at the dealer now. Has it been determined what is causing it and has anyone had it fixed?

Agree. Please keep us advised. Even if I get it fixed I'll never buy another Hyundai vehicle.

Periodically the ac just stops blowing out of vents.The air is still blowing in dash.Its as if a flap in the duct work closes.Then eventually it starts working again.They changed the blower when I told them that was not the problem of coarse.Any help please reply its still under warranty.
Service manager told me it is the Thermister freezing up and needs to be replaced. Said its a common issue? awaiting part and repair.

Hi All - Thank you for all of the posts in this thread. I actually printed this out and gave this to Hyundai Dealer. I said...look at this. This is what is happening to me exactly. They determined that the freon was actually filled up too much. They took some out, so that it is at the recommended level. I have been on two long trips since....and no issues.

The evap temp sensor was replaced and did not fix problem, as it happened while driving home from the dealer repair after 20 mins. I will now try the freon reduction as mentioned above. It seems nobody cares at genesis to communicate this problem to tech teams.

My 2018 G80 is doing the exact same thing. I took it to the dealer and they could find nothing wrong, but it quit again today on a long trip and now I'm 5 hours from home with no air conditioner.

My 2018 Genesis G80 with less than 17,000 miles is doing the same thing. I have taken it to the dealer twice in two different states as it only happens on long trips. They completely drained my Freon, refilled and checked for leak. They could not find anything.
I don’t understand why Genesis won’t deal with this.
