This has happened twice with my 2015, both times just as the battery depletes and the ICE comes on. The air coming from the A/C vents stops blowing cold. I'm not sure if the heater is coming on or if it's just the hot outside air coming in. The temperatures are still in the 90's here, and I normally run the A/C in Comfort mode at 76F w/recirculate. When this happens, I can lower the temp on the panel to like 74F and some cold air comes back. I'm going to try switching to Hold mode and see if it happens then. But I very rarely deplete the battery like that and I'm wondering if this is normal?
