opinions? Noise occurs while moving, any speed above 0 and below 20, while applying any type of power. Does not happen in regen, coasting in neutral, or reverse. I can vary the pitch and loudness of the noise by applying more accelerator, and it does not matter the speed, as you can hear in the video. Opinions? Have you experienced this? Did a west coast road trip last week. Covered climates from Mountain and below freezing temps to desert and 115*F and 6,500+ miles of freeway driving in under 1 1/2 weeks. EDIT: This is my second drive unit, with about 20,000 miles on it since December.
