Owned the S, X, 3 and Y. When driving my CT around 30-50mph I hear a faint but distinct whining sound that seems to have a certain beat frequency change that is in tune with speed (higher speed, faster beats). It is not a constant whine that slowly goes up in frequency with speed (this is normal for electric cars) the whining beat frequency changes several times per second, faster and faster in-sink with every turn of the wheel (my theory).
The modulated whining sound is not loud at all, but I would like to eliminate the 'modulation', if possible. The noise is originating from my electric motor,(s) as if the load changes several times per second while smoothinly accelerating or regening.
The vehicle does not shake at any speed or at least I don't feel it.
Is this a motor install defect, alignment, chassis or a tire issue? Or is it a dual motor calibration thing?
Thanks!
