Anybody else notice a whistling noise when accelerating? I have a 2016 2.5 outback limited and I've noticed sometimes when I start the car and drive there seems to be some kind of whistle when i accelerate. The harder i accelerate, the louder the whistle noise becomes. Other times I start the car and I hear no noise whatsoever. Just seeing if anyone else has a whistle from theirs and they have found out what it is.
