NHTSA Complaint #11571546 — 2015 RAM 1500

This has happened 3 time now and basically has been parked since. We have had it to the repair shop and they couldn't find anything. Repair shop even has contacts who work for Chrysler in CO. We live in SD, it's winter. So vehicle need to warm for some time before driving. On all 3 occasions vehicle was warmed up for 15-30 mins. Hop in pickup to leave our yard and shift into drive. Steering wheel acts as if it's still locked. 1st time it lasted 5-10 seconds, I forcibly tried with all of my might to turn the wheel but could not get it too. Also tried shifting though gears while rolling. It just suddenly unlocked. The 2nd and 3rd time it lasted 30-60 seconds before it unlock. As a parent this vehicle isn't safe. What if it locks up while driving at 80mph on the interstate while my kids are in the car with me? I do have a video of it but it won't allow me to upload it.
