In November 2013 while the MDX was parked overnight, the driver side rear window regulator failed and the window dropped down into the door. Two months later, in January 2014, the identical failure occurred on the passenger side rear window regulator and that window fell into the door. In both cases a plastic piece that anchors a cable suddenly broke in the same manner without warning. This failure does not appear to be an improbable event, given these facts. I have retained both broken parts and offered them to Acura. However, they are not interested in investigating the incident. When this failure occurs, the window cannot be rolled up. This could be a driving hazard if it occurs in windy, foggy, and/or rainy weather. Besides greatly distracting the driver, there is no way to prevent excessive moisture from entering the car. This situation may cause windows to fog or become wet on the interior of the vehicle, impairing visibility. Obviously, the security of the vehicle is compromised, as well.

On window rollup, rear window slid out of drive mechanism and fell to the base behind door panel. Glass did not shatter, and I was able to maneuver it back into position temporarily to take to dealership for replacement of drive mechanism. No weight or obstruction was put on window as it was being electrically closed. This is the third time a rear drive mechanism has failed on this vehicle. Both other replacements were handled under warranty and good faith. This unfortunately is going to be an out of pocket fix to the tune of 350 dollars. I believe that this is a flawed design and could have resulted in broken glass, an unsafe situation considering my daughter was in car seat next to window.
