Sorry to drop in so late on the feed but I am having the same problem. 2015 Fusion Energi Titanium. 108K miles.
I kind of discribe it as a humming sound at the speed of rubbing your hands together. As I leave a stop, the rubbing gains in speed as the car does. Always the same sound at the same volume level. Not real loud but loud enough to think others outside can hear it. I can't hear it at speeds over 40 because of road noise, or the bitchen stereo. I had a service today and they checked the brakes and rotors and found nothing. Other than that, I love my car!
Has anyone had any luck or diagnosis?
Thanks to all.
