Air Suspension warning

I recently hit a car that turned in front of me. Long story short, got truck out of repair shop. Total repair included a front end alignment. After about 30 miles I got a "Service Air Suspension" warning on the evic. Also, cruise control no longer worked, could not raise or lower the truck. The Trac Lock Off indicator came on. I called to set appointment to take it back in, but the next day when I started it up, everything worked again and the warning was no longer in my message memory in the evic.
It is a 2016 Crew Cab, 4x4, with regular length bed. Anybody have any ideas while I'm waiting? Amazing how many mechanics still don't know about the air suspension.
