have you seek any mechanics' opinion yet what could be the problem? Do share if there is. Thanks!Hi, did you guys figure it out? My car is making whining noises from the rear at higher speeds. Even when the engine revs back down (from eco mode) and I'm going 140km, the noise is still there. the faster I go, the higher pitch it becomes. If the car slows down, the noise also starts pitching down until you cant hear it anymore.
