I own a BMW X5 3.0 and have chronic problems with the windows in my vehicle. The rear driver side door window shattered unexplicably about
18 months ago while driving down the road. A month ago my passenger front door window dropped straight into the door and shattered for no reason and now my driver window had retreated into the door and will not come up. Is there a problem with the mounts that hold the window glass to the motor or something? Is anyone else having problems with the windows?Jack
