So I have a 2013 Mazda CX-9. Roughly 106k miles, very well maintained through Mazda. August 2018 I had a full front end brake job. New rotors and pads. Within a week there started with a faint squeak from the brakes, didn’t think much as they were new although I did bring it to the attention of the dealership.
Mover the last few months the vehicle has been in shop for the same issue with the noise getting louder! Noise is a squeaking almost coming from the driver side specifically. Roughly about 25 mph and whether it he vehicle is warm or cold it’s squeaks/rubs. The dealership says there is nothing NOTHING wrong with it! We checked the rotors and the inside of the new rotors that were placed in August have a groove on the inside all the way around on both the passenger and driver side.
