I did a little reading here on the forum and it looks like it isn't uncommon to have rotor warping at low mileage on these newer Volvos. I've got an S60 T6 Polestar, 8400 miles, and I'm getting fairly substantial vibration now under moderate braking above 40 MPH. Is this pretty common? Bought the car in August of last year and I'm worried I'm going to be just over the 1 year "adjustment" period for the warranty. I'm definitely not interested in shelling out the cash for new rotors on this lease.
