I'm having an issue where there is no change in the engine sound when sport mode is engaged. I have had the ACM replaced for the dead battery issue, but now it is always the quieter engine sound. I have spoken to Ford at length and have gotten nowhere. Today they told me that this, "isn't a feature on your car." I'm at a total loss as to what might be the problem or what to do next. Anyone had this issue and gotten it resolved? Thanks!
