I love everything about this truck, but it is unfortunately ruined by inferior air conditioning.
I have had it back to the dealership three times and they tell me it is working as per spec, but also agree that the spec is inadequate.
FYI, the spec is to blow air at 20 degrees below the outside temperature.
I can tell you that if the outside temperature hits 79 degrees or greater, you need to roll down the windows, or you will sweat in the car.
The dealership has tested my 2011 a/c performance against older models and they claim that the older models work better.
There is nothing that can be done about it.
It is a design flaw that ruins the truck.
