So I just bought a 2017 ford mustang Ecoboost, 40k miles, I had a multipoint inspection before I bought it and it was in great condition. Unfortanettly today I didnt see a dip in the road and I hit it pretty hard and now I hear hissing when I accelerate (was not hissing before that dip) I am taking this into the dealership in a couple days but does anyone have an Idea of why this is happening
