Crazy 2008 Odyssey

My two month old Odyssey has a glitch in the power window system. Over the past few weeks I have had windows open all the way down with no one pushing the control. This has occurred three times. Each time it was a different window. Each time the vehicle was moving. Before I head off the dealer and get the “can’t duplicate the problem response”, I thought I would run this by you guys. Thanks in advance for any advice.
