The switch is located on the left side of the steering column under the air bag package. It should be covered by a warranty because it was just replaced in March at a chevy dealer. They better not recharge for labor! Had to be towed cause you cant get the shifter out of park. A very stupid design. I saw on youtube some cars have a button or a slot you can depress to release the tranny. Don't know about this one or where its at. It will start the car but wont turn to shut it off and the brake pedal wont release the shifter to drive it. The design makes no sense.
