2016 Ford C-Max....love the car; hate a few annoyances...
About 2 months following Purchase I began to hear a Thud\perhaps more like a thump from the rear Right Cargo area. Paying close attention when I hear this noise I have pinned it down to when I pull from a stopped position at a slow speed where the Electric engine is powering the Car and quickly accelerate were it hands off to the Elec Engine I hear the Noise. If I watch the instrument Panel I can see the Blue Band, hear the noise and see the White appear....(Elec handing off to Gas). If, I slowly start, see Blue Bar about 1/3rd up and than accelerate and Elec takes over, I don't hear the Noise. Also, all coasting speeds......switching from Elec to gas, I never hear any noise. So I hear this noise only at a slow startup with a quick acceleration to change from Elec to Gas. Obviously there are solenoids/relays or whatever the part must be called in this rear Cargo area that is handling the Change-overs, charge the battery, Battery running elec engine, etc.....and it would be a guess on my part, this part is the cause of the Noise. Can't think its normal because 1) I don't recall this noise until several months following purchase 2) it only makes the noise with a slow startup and fast acceleration 3) a friends C-max...never makes the noise.
Anyone else with any year C-max experienced this Noise? Yes, eventually I will take this into my dealer but although the noise is annoying, the C-Max is running great with 42MPG is a Very busy loaded with Traffic lights community.
The other annoyance is a HISSING sound coming off the brakes, again, other then the noise is annoying, the brakes are great...anyone experience this noise?
