Driving on the highway when the steering warning light came on and then I had a loss of complete steering on the highway. Somehow was able to get off the highway but not completely off the road.

There was no warning before that just went out while driving at highway speeds on the highway. Also had to wait two hours for a tow.

I was driving down the highway, and my wife and I decided to stop at Costco to get protein bars and gas for the drive home. We also had a [XXX] , [XXX] old, and [XXX] in the car. As we were approaching the end of the exit ramp at approximately 30 miles per hour, the engine jerked the car two or three times then died. When it died, I lost power steering and the car slammed to a stop. The car also displayed an alert about my tow breaking system. I tried to restart it, and smoke began rising from my engine bay. I stopped trying to restart, and got my family onto the hill beside the exit while waiting for a tow. The tech at the GMC dealer stated that the engine had seized on me while driving. The cam shaft can rotate a small amount one way before getting blocked, and likewise the other way. Tech believes that the bearing is responsible, but will not be doing a tear down until September 2.
