Has anyone experienced a ringing or humming sound from the engine while at a stop? I noticed it when I let my beast heat up as soon as I stepped out I hear the sound coming from the front end. It also comes up when I am at a stop light. Any know what it could be? :confused:

It could be the aux. electric fan coming on.

or.. if you have one of the wireless headsets turned on and the volume is up.. regardless if you have the DVD or radio on or not, you will hear a ringing/humming sound from the headsets. check that they are turned off.
