My dealer couldn't find any problem; they had the car for 4 days and ran several diagnostics in the shop. I told them to take the car for a ride to see if they could duplicate the problem on traffic conditions, but they had no luck. They did mention there's a bulletin from GM saying that if you use the defroster, the recycling function may fail. The only temporary solution is to push the recycling button twice to force the outside ventilation inlet to close.
