A retaining system for a motor vehicle includes a vehicle body having a door opening with a frame disposed therearound. A door is mounted adjacent the door opening and includes a vertically moveable frameless window. An actuator is coupled to the frame and further coupled to a retainer member. The retainer member is moveable between engaged and disengaged positions relative to the frameless window as powered by the actuator. A controller is configured for determining whether an instantaneous vehicle condition is met or present, and moving the retainer member to the engaged position to retain the frameless window against the frame or vehicle body when the vehicle condition is detected. The vehicle condition may include a predetermined vehicle speed, an aerodynamic pressure reading, a direct aerodynamic pressure or vacuum, a door lock activation, or other like condition for detection by the controller.
