I have noticed a weird noise. I swear it wasn't there when I bought the car, but maybe it is more noticeable with the windows open driving next to a wall/building/car. I can hear it inside the car with the windows up if the radio is off. It is definitely NOT brake noise or tire noise. It is DIRECTLY correlated with whether the electric motor is engaged. I testing this by coasting along in regen1 (no noise) and tapping the accelerator (noise as soon as I press) and tapping the brake (noise as soon as I press) and holding the left paddle (again, noise on regen). It is either the electronics (inverter/PWM/motor/etc), or something mechanical (bearing/shaft/gear). The noise doesn't change pitch with speed, which makes me think it is PWM noise (even though the volume doesn't seem to increase with engine power). The pitch seems pretty high to be gears. Maybe a bearing. I also don't know if the motor is 'clutched' in and out, so it would be spinning even while coasting.
