Just turn 12k mikes and I'm getting a loud hum when the accelerator is pressed going over 70. It started a couple of thousand miles ago and seems to be getting worse. As soon as you let off the pedal, it goes away and starts back as soon as you step on the pedal again. Kinda sounds like a ICE engine noise. Anyone experienced anything like this? I keep getting comments from Tesla like, "thats the way they all work", when I complain about the radio not working or the squeaky sound that resembles letting air out of a balloon every time I accelerate hard. Any suggestions or similar goings on?
