My 2016 front suspension drops about 1" overnight and then raises back up when started in am. Is this normal? Sorting thru some knocking in my front end when going over bumps and this question popped up when searching. I don't believe its the valve block as they apparently upgrade these after 2013.

I had the back end of my 322 do that. It wasn't anything wrong with the air system, but a faulty sensor. The failed sensor meant that the others tried to level the vehicle to match the faulty one.
