Last week I noticed that when I put my MY in drive, I get loud static or white noise coming from the external speaker located near the right front wheel well. When I shift into reverse the "alien sound" takes over and I no longer hear the "loud static". To be 100% sure that the sound was generated by the external speaker, I removed the cable connected to the speaker and put my MY into drive, no more static sound. I reconnected the speaker wire, put my MY into drive and the noise returned. Anybody else experience this? Anybody know if this is a safety "feature" that Tesla has introduced to allow pedestrians hear our Tesla's in parking lots?
