Question type: General

Every now and then, just at random times, a high pitched sound comes through the car's built in stereo speakers. It sounds almost like an amber alert or PBS alert coming through as it sounds on TV.  Lasts a few minutes, and then stops by itself.  Is this anything to be concerned about?  No indicators, (i.e. dash messages, etc. show any reason )  for this alarm.

Sounds like the OnStar.There could be a malfunction that is making it activate.
