Hi there. I picked up my accord a while back and as I was driving this week, I heard a noise like a whistle when I accelerated and when only I accelerate. Decelerating it quiet. This noise wasn't there before. But now it is and the passengers in the back seat could hear it as well. The car only has 2k miles and the tires are stock and nothing has been added to the car. Is this the infamous CVT whining or something else? Up till now, I haven't heard it and my old accord sport didn't have this problem. Dealer worthy?
