The seal of the roof-mounted antenna housing adhesive was faulty. This caused separating from the vehicle allowing water into the vehicle, which damaged emergency call components and equipment. BMW told me this was a know issue, but that NHTSA had not yet applied this to my vehicle. Please issue an advisory on this known issue. My car is under 40,000 miles and fairly new still. Adhesive should not be deteriorating this early. Preventative maintenance could not have addressed this factory issue. — Excerpt from BMW inspection: Concern Critical Client States Emergency Call Malfunction On. Aux Battery Replaced Twice.
