Driving car locks up check engine light comes on says check power steering, we aimed to side of the shoulder car dies wouldn't start. We had to wait on side of a interstate for 3 hours to get a tow truck, very dangerous.
I was driving on a highway at 65mph. On a straight portion of the road the engine light came on , the engine revved up to over 4000 rpm, the power steering locked up, and many other lights came on on the dashboard display. This was a very dangerous situation trying to control the car. I was forced to slow down and when I reached 40mph the power steering came back on. The engine was still running over 4000 rpm. Most of the dashboard display lights went off except for the check engine light. Had to drive under 40 mph until I got home. While this was happening my onstar sent me a notification that there was something wrong with my transmission. The car was then towed to the gm dealer. At the gm dealer they could find nothing wrong. There were no error codes in the cars computer.
