Hi, I also have a 2014 energi titanium fusion. I called ford headquarters because my dealership could not help me with the very low backup sensors. Ford told me that the titanium is the top of the line fusion therefor it is insulated differently from other fusions so the car has far less cabin noise than other fusions. They state this is why we can not hear the backup sensors. Sounds crazy but I have no other choice than to believe it.
