2013 C-Max 70,000 miles. The past several months we have been getting a raspy/whiney sound, almost a grinding sound. Seems like it's in the front end, but may be under car. It happens whether the engine is on or on battery. I happens whether we are under load or just coasting. It worse around 40-50mph and pretty much clears up at 60+. I assumed it was tire/wheel related, but I had tires rotated and it didn't make a difference. It doesn't feel like the car is going to fall apart or explode, but it is annoying. I tried getting the Ford service people on a quick road test, but they won't even look at you unless you plan to leave the car there for 2-3 days before they get to it. Any thoughts?
