Hello,

I would appreciate any input on the issue I'm having on my 2016 Patriot CVT ~60K Miles.

There is a vibration that is felt when under medium/heavy load. Once I let go of the accelerator/pedal the noise stops (i.e. cruising speed).
If I slightly accelerate at full highway speed I do not hear the noise but once I give it a little more gas I can hear the buzz/vibration/whine noise.

The transmission does not slip as far as I can tell (not sure if CVTs are known for slipping or can slip).
I recently changed the front lower motor mount because the car was slightly vibrating at idle. The vibration reduced noticeable now there is only a very minor vibration at idle sometimes.

Not sure what this can be.

Thank you.
 
Sometmies the whine is a bearing going out on the transmission:

"The most common abnormal bearing noise concern with these units is related to a rotational whining noise in Forward or Reverse. The noise gets worse as vehicle speed increases — sometimes it may even sound like a differential noise. A pan examination will reveal a magnet with a good amount of steel hair on it, which means there is something “making metal.” This happens when the pulley bearing races become pitted, causing metal flaking. To address the problem, the bearings must be replaced, and that requires unit removal. "
