I get this noise that comes only under 5 mph and stops completely around 6 mph. No noise if I switch to neutral. Here is an audio recording that I did from iPhone placing it in the trunk. Tesla Noise Recording.mp3 0:00 to 0:0.07 : you will hear the noise as I gently accelerate from 0mph. it stops at 0:07 as i go above 6 mph. 00:37 : I hold the speed steady at 4 mph and you can hear the sound very clearly. Is this milling noise? grinding noise? balloon squeal? Note: I know there are plenty of topics on noise and it is possibly that this is already discussed in one of those, but my limited search did not bring up a topic that discussed this one.
