I have not tested this myself as I habitually disable auto stop when I begin driving, but also had a 17 Cruze before my TB. My cruze also disabled auto stop during low temperatures. While I would be surprised that Chevy removed this feature, you can simply disable the auto stop with the button (which wasn't available in my Cruze). It's possible that the system works differently and has a different temperature threshold for disabling auto stop. This is merely speculation, but my TB has auto temp control (unlike my Cruze) so that may also be factored into the car's "decision" whether or not to disable autostop.
