I purchased my 2022 K5 GT-Line on Aug 7 2021. On Aug 17 my wife were taking the car to the store in the afternoon and realized that the A/C was not working. The day I took the car to the dealer, 8/19, the a/c was perfect and the service agent told me not to leave the car since we couldn't replicate the problem. 4 hours later, there was no a/c again and I took the car to the dealer. The service tech admitted that he had experienced this problem with other KIA cars and it seemed to be a problem with the computer thinking the engine was overheating shutting the a/c compressor.

Hi! So I just had the same thing yesterday. Tried the AC for the first time in a while and it's blowing hot air. Mine is a 2022 gt-line FWD. What ever came about with your issue? Thanks!

It took 3 trips with extended stays at the dealership, but the problem was solved. First, I was told the system was under charged when the car was shipped. After topping off, I was told "this is how it's supposed to be". Finally, they diagnosed a refrigerant valve that was working intermittently. That solved the problem. I live in Florida and I run a/c every day all year long.

The guy I talked to this morning said I could leave my car and get in sooner, and I didn't think at the time that I guess they might be required to provide a vehicle for free since it's under warranty. I may need to call back.
Gotcha. I appreciate the info! I don't run my AC much yet, but it was 90 yesterday in Indianapolis and I was sweating like a big without it. I'll mention that in case it happens to be the same thing.
