Thanks for the input. At least others have been experiencing this unusual noise. I'll just keep driving it and see what happens. I have to say that I don't understand why the C-max isn't more popular. Of all the cars I have owned over the years, my C-max is more fun to drive, and more of a car then any of the others.

My 2013 C-max has 82000 miles and in the last 3 months has started to display a intermittent low moaning sound from what sounds like the underside of the vehicle. It comes and goes as the speeds change. It will go away temporarily if i let up on the throttle and then come back as I accelerate again. The noise is louder when accelerating in the lower speeds. Has anyone else had this problem ? And if so, is it an issue that needs attention ?
