When cold sometimes not able to shift from park to any other gear or neutral. after driving, able to shift from drive or reverse back to park but get message saying "car is not in park - shift to park". when in neutral sometimes not able move shifter from neutral to drive or park. when contacted dealer for service they seemed to be familiar with the problem. my concerns are not being able to drive car on demand, as well as not knowing if car is truly in park or not.
