Hoping someone can help me here.

Recently been getting a reverse squeal whether the car is warm/cold or wet/dry. Weirdly, the squealing occurs whether or not I'm on the brakes.

I've tried searching but nothing has described my problem.

Car is a 2015 GS with approx 120k kms. Pads/rotors were recently changed in this past fall.

Thanks in advance for the help!
