Brake light stays on and cruise control won't work, and vehicle will not shift out of park. Dealership is aware of problem.
Left out of driveway went two blocks parked car front of friends house, two hours later I proceeded to leave. Started the car applied my brake pedal and got ready to shift in gear when it didn't move even the button on the side wouldn't go in, turned the car off and called for a towing truck. Towing truck came and said that it might be some switch on the brake system because he towed at least 4 that same week for the same problem. Also the brakes lights will not come on . This poses as a danger because if a person is driving and you can't take it out of drive the only thing you would be able to do is stop the car with the brakes and keep holding the brake until you get help you can only hold the brakes for so long.
