yea my shit did the same thing,...do you have manual windows? if so,..when you roll your windows up,..you probably crank it that extra little turn when its already at the top,..this will cause the track closes to the speaker on the door to bed which in turns sends the window off track,...all i tried to do was bend that track back to being straight as possible,..my window has been okay ever since,..its been like 9 months now,..the track im talking about is the one which is held by one bolt close to the speaker on the door,..you have to take off your door panels to do this
