Hi there:

 

First time poster!

 

My C-max seems to have recently developed a strange noise ("whining") when I am going from a stop until it gets up to speed (i.e. until it gets to 2nd gear). Also makes the noise when idling if the ICE is on (if heater or A/C is on).

 

Here is a video demonstration. Any ideas or suggestions would be greatly appreciated. Thank you!

Maybe electric coolant pump motor.  You are pointing at the outlet air pipe that is connected to the throttle body .  I believe the ICE coolant pump is maybe 6 inches below the throttle body.  There is also another coolant pump for the inverter coolant loop.  It's near the bottom of the radiator. You can see the two inverter coolant black lines  just below and to the right of where you are pointing in the video.  The inverter would be working hard (heating up when accelerating from start) to supply power to the electric traction motor. I don't know the control algorithm but perhaps this coolant pump is variable speed and reving high causing the noise when accelerating from stop.

 

If you can find a long pipe or screw driver.  Place one end on the various components in the area the sound is coming from and the other end to your ear.  You should be able to tell what component is making the noise.

To me it seemed to very with ICE speed, for sure take it to the dealer, that isn't right.

Sounds like the AC compressor to me.  They make an awful clatter.

Thank you everyone for the replies. I'm hoping to get her in this week to get looked at.

 

I don't think it's the AC compressor though; I never have it on!

 

And yes, it does vary with ICE speed. From a dead-stop until I hit 40 km/hr (sorry, I'm Canadian) the noise is present and then I'll let off the gas and it's ok. Or, when it shifts out of first (as much as you can tell it's shifting from 1st with a CVT).

Being a CVT it doesn't shift, it's all done with the Electric Motors. :)
