LF (2015-2019) Sonata/i45
What would cause the rotors on the rear brakes to go out of round on a 2019 Sonata 2.0T with 9500 miles on it? I had to bring the car to the dealer today to find out why there was this "thump thump" sound while driving, and they told me that the rotors had gone out of round on the rear brakes...
