2010 chevy Cobalt pulled into a parking spot and put my car into neutral and the emergency brake up and went to turn the key to the off position and it would not turn. I checked to see if there was a locking mechanism on the steering wheel and if I hadn't fully put it into neutral and neither was the issue. Tried to get it out a couple times then eventually called onstar and they told me the tow guy would be able to get the key out of the ignition. They sent a tow truck but when the tow truck came he couldn't get it off I spoke to him and told him I did not have a ride home and I was an hour away from home. He said I could drive it home. The car was idle for over 2hrs and used about a quarter of a tank of gas. I drove it home and stalled it by puttin it in 1st gear and letting up off the clutch. Then un hooked the battery. I will be bringing it to the nearest Chevrolet dealership in the morning. Today's date 11-12-2010 8:21pm previous issues as well when its very cold out when I go over a bump the radio will shut off and when I push on the console near the radio it shuts off as well.
