The car had its own mind. And it was going where it wanted to go. Reporter: Walter lubo was driving his 2006 chevy cobalt just last month, when the power shut down and the steering locked. I flipped. I spined out to the middle of the road. My air bag did not deploy. Reporter: Megan Phillips says the same thing happened to here. All of a sudden, I had no control of the car. And I thank god I still have my life. Reporter: Gm is now recalling 1.6 million cars. Models from 2003, to 2007, including the chevy cobalt, pontiac sole cities and ion. The problem was with the ignition, shutting down the car and its safety system, including the air bag. Gm says a heavy key chain or rough roads can cause the problem.
