Happens to me too every now and then. Usually only at the start of the drive.I put a meat thermometer in the air vent and took a video to show what my brand new CX 30 is doing. Every time I accelerate the compressor kicks off and the air warms up about 14 degrees even with the airflow on recirculate. Others have suggested it is normal for the compressor to turn off when the throttle is above 50%. The video clearly shows that I am accelerating slowly, certainly less than 50% throttle. I did the same test in a Kia Optima and it cooled to 47 F then went even cooler down to 45 F when I accelerated.
