2015 Yukon 5.3 RWD my AC quit working April 2017, took it to the dealer May 9th. Have had several phone calls with them, "needs a condenser and its on backorder" they say. Had a conversation with GM customer service on chat a few days ago, and WOW they are useless and unconcerned with my satisfaction or the well being of my young kids. I currently live in So Cal but from AZ and still travel there often. Customer service said I would have to "take it up with the dealer in Arizona" if I am seeking some kind of compensation/rental. I told them that I will go to jail if the cops see me driving in 118 degree weather of Phoenix with a 2 yr and 4 yr old in the back seat. It is now June 26th, still no AC. Contacting lemon law atty now, they can have this Lease back.
