While parked at a gas station the front door passenger power window slammed opened/down during normal door closure. window regulator assembly was removed and found defective. internal cable windings were kinked and caused plastic within power window motor to break allowing cable/window to move freely and fall to open/down position. safety of vehicle is jeopardized...if this happened at speed it could certainly create a startling event that could cause a driver to lose control of the vehicle because of the sudden unexpected distraction by sudden rush of wind noise and environmental elements. *tr
