The brake rotors exceed the manufacturers run out specifications and tolerances. This has been happening vehicles as early as 2018 model year. In my specific case I bought the car with 3600 miles on it as a certified vehicle from a Volvo dealership. On my drive home I could feel the braking pulsation in the steering wheel. The dealership measured the run out and it exceeded the manufacturers specification on all four corners. I then joined a Facebook Volvo owners group and found out there are several members that have had their rotors replaced by the dealer in many cases multiple times because they are either installing a non-conforming brake rotor or the part becomes defective with use well within the warranty period. If the vibration caused by the rotor run out continues to increase without mitigation it may cause the brake pads to deteriorate at a high rate reducing stopping distance or cause the vehicle to swerve.
