Well at 750 miles the other morning the trans would not shift out of Park and got a CEL. Tried cutting off engine and restarting several times, the car would start and run ok but would not shift out of Park and CEL remain on. Waited about an hour and a half and tried again and everything was okay and has been. Visited the dealer today and they did a firmware updates. Hope this correct the problem. Planning a two-week trip starting next week.
