The noise is likely new/stiff (cold) bushings.
For me, this is a every winter as soon as it drops below twenty degree thing.....becomes less noisey as I drive a bit but for the most part is present till temps (overnite) stay above freezing.
Not just the Cruze.....wifeys Malibu sings the same song with the cold nights.
So, for now, I'd say don't frett.
I'll leave your other question for those who know more about that electronic gobblygook.
