My 2019 has 62k on the clock and I took it to the dealer for a 60k service. They said the only thing required was plugs and after inspection of transmission, they also changed the fluid. I specifically asked them to inspect brakes and I was told at least 20% of pads remained. The service Rep also said that the breaks will make some type of sound when the pads need replacement. can anyone elaborate on the type of sound if in fact that was correct?
