NHTSA Complaint #11622902 — 2016 GMC SIERRA 1500

While driving and making a turn at slower speeds, such as parking lots or intersections, the entire dash cluster including the radio screen will go black. The steering will completely lock up and jerk back to the opposite direction. At the same time the Park assist, stability control keeps flashing on and off. Sometimes the truck will shut off and then tell you to roll down the driver window and roll it back up. It is random and you never know when it is going to do it. The only fix I have found is to stop in the middle of the road and restart the truck. You can not drive off the road to do this because you cannot control the steering. I almost drove into oncoming traffic when it did this during a turn at an intersection. I have taken it to the dealership and they say then cannot duplicate it therefore don't know what the fix is. I have read multiple complaints on this on line. I have video but it is too big to send in this email.
