Got to work this morning, shifted to Park and car started moving backwards. Attempts to shift to any other gear had no effect. Shifter moves fine, it just does not do any thing. Shut the car off and not will not restart. Any ideas what this is??? FWIW it is unseasonably cold here, 40 degrees. Also, it just occurred to me that for the last week or so the automatic headlights want to be on in broad daylight, abnormal behavior.
