This used to happen on my Pontiac Solstice OFTEN. In fact, it's one of the reasons I got rid of that car when I got my Camaro. Once, it stuck on and would not turn off. Could not turn the key to the off position. It's hard to take a car on any lengthy trips when you live in fear that it won't turn off or the key won't come out. The Chevy dealer dealt with mine by replacing the ignition switch... three different times. The one time, the service manager told me that the "tumblers" (or whatever they are) inside where you put the key, the little things that match your key cut, had fallen apart and were jamming and not allowing the key removal.
