Just bought a brand new 2016 i touring and am very happy with it except for one issue. When accelerating and decelerating there is a high pitched whining noise. As I accelerate the noise gets higher and as i decelerate the noise gets lower (think bomb dropping sound effect -- this youtube before the explosion sound is actually a pretty good example of what it sounds like decelerating: https://www.youtube.com/watch?v=FLvV4NegF0o). It's a pretty quiet sound and some people haven't been able to hear it but it is bothering me.
I know it's not the dealer plates whistling in the wind. Any other ideas about what it could be?
