As to main transmission issue you mention here, I have not had (thankfully!) but as to getting out of park, known issue with shifter and mine was replaced under warranty... your tech should be able to reproduce as mine just started doing it more and more...
As to the locks, this is due to the speed sensitive locking setting and unless you either DON'T want it to lock at speed or you just get used to hitting the unlock button up from (either door) OR the rear passengers can pull up the lock at rear of door to exit... these are the only solutions in this case.
