Door Latch problems of the 2009 Chrysler Town & Country

The power doors, both sides and the rear hatch, open at random, either when vehicle is parked and turned off or while driving the vehicle. I have found my vehicle on the street with a door open, once during a snow storm and the inside was inundated with snow. I'm afraid I might find a homeless person sleeping there or a nest of skunks perhaps, or maybe stripped clean by a thief. The key fob has been eliminated as a suspect of inadvertently operating the doors. Once I closed a side door with the button on the inside of the car and after a few moments, it reopened. On three incidences doors opened while driving. This I assume to be a real safety hazard. Imagine if the rear was packed with luggage or groceries and the hatched open while driving on the highway. I wouldn't want to be the car driving behind me! the car was purchased 09/08/09 and currently has 4400 miles on it. These events happen sporadically and I have yet to have the dealer look into it (I had to cancel the first appointment due to a snowstorm) but I suspect they will think I'm crazy just as I thought my wife was crazy when the first time she told me the rear hatch opened while driving. I didn't believe her until it happened to me a few months later. And it happened to me again more recently.
