Good Day all,
I have a 2018 Jeep Compass bought it back in December and for the last 3 months I have been dealing with a loud metal on metal screeching noise coming from my back passenger tire area. I went to my local dealer and they said that it is probably just a rock stuck between the rotor and the flex plate and that there really isn't anything that they can do about that.
The noise only happens when I am going in reverse so i am starting to get skeptical on it being a rock cause if it was a rock it should happen going forward as well. Unfortunately my Local dealership does not treat me very well because i purchase my Jeep in another city and dealership instead of them so they are not really chomping at the bit to figure this out for me.
So not sure if that help any but I figured I would share my similar Grinding Noise issue.
Good luck with your hunt for answers,
