As an update to this, the only time I ever notice the issue is with air recirculation off. I suppose that makes sense as with recirculation on, I'm getting the current temp (which is typically roughly right). It seems like when it's not actively trying to reach a temperature because it's already close enough (like when a thermostat shuts off because it's within tolerance) it then just lets outside air in.
I usually have recirculate off and never get blasted with cold air.
Could be a stuck damper door too and perhaps is a door that is out of the loop when you recirculate.
I don't know for sure if it applies at all, but do you have the latest radio update? Not sure if some of the logic is in the Uconnect firmware.
My guess is, that it's not and the Uconnect is just "Buttons" to the separate HVAC system.
