2018 G80 3.8 AC Problem

[Ed Springer]

As I drive on a long trip (2 hours or more) my 2018 G80 3.8 AC will drastically slow down to practically nothing. I can bearly feel a very tiny bit of air flow. If I restart it after 20-30 minutes, it will properly flow again. This will occur several times on a 6 hours trip. Any ideas of the cause/remedy?

Yes, it has been discussed a lot. Your evaporator is freezing up. The first step is to check the refrigerant level. You can reduce the frequency of this happening by selecting recycle and manual high fan speed.

I'll start by stating that I love my 2018 Genesis G80 Sport! One of best cars I've ever owned with one exception. This is probably the strangest (and most annoying car issue I've ever experienced). It's happened 3 times in the past year, so I've pretty much figured out when it will happen, but...

Follow the information Joegr pointed out. If low on refrigerant, you have to find and fix the leak or it will happen again. Given the age of the car, minor loss is fairly common. In my case, the evap coil had to be replaced at $1500.
