I had a 2017 and had issues with the AC not cooling after I had driven for about 45 minutes. At the time the dealership did not think I had the issue of the compressor freezing up which was a known problem that at that time there was no fix for.
A year later I demanded an answer and after the service manger took my car for a day and saw the problem for himself he stated that he felt my AC was experiencing the known issue and that there was now a fix for it. It turned out that I had a bad evaporator core seal that was not seated properly which was causing a leak and causing the compressor to freeze up.
The entire dash had to be removed to make the repair. There is a service bulletin out on this so make certain that service pulls up the bulletin. I had only had my car for about 8 months and 5,000 miles when I experienced the problem with the AC and it was not good. On a couple of occasion it was extremely hot and the AC would fail and I would be driving a 300 mile round trip with no AC.
You are probably getting very little to no air flow from your AC vents and for the most part you are getting warm air. It is a warranty repair so you will not be paying for it.
There is also a Thread on this issue which I have several post about my experience concerning the AC issue.
Good Luck
