When I shut the car off today, the ignition switch wouldn't turn to the key removal position and the "park" indicator in the instrument cluster remained lit up.

I was able to start the engine again, move the gear selector into gear and back in park and the key came out after I shut it off.

Maybe unrelated, but I did run over a snow / ice berm that scraped under the car just before the problem arose. Wassup with that?

Happy New Year!
