Rearview Mirror Vibration

[jhkj002]

Hey everyone... I have a 2017 MKZ Hybrid. Purchased as CPO just under 2 years ago... so still has a warranty. When driving on an uneven road, bumps, etc... my rearview mirror vibrates terribly. It's not just the sound that's annoying, but you can feel the vibration. The mirror isn't loose. It's horrible. I took to the dealer and they said I need to replace the rearview mirror, but the part isn't covered by the warranty. Do I have any recourse here? Anything I can do? They want $644.34 to replace it. Ouch!

unfortunately - I paid for a new mirror at the dealer - and its right back to doing the same thing...
