I have leased an Audi Q5 and on the last service before the lease expired, they said I had completely worn out all my brake pads. My car was at just 30K kms and the brake pads are supposed to last for nearly two times that. Furthermore, I am super careful with braking since I also use the TD Insurance app that monitors braking, acceleration and driving to give discounts on the premiums.
The unnecessary brake pad change cost me $2500. They did ask me first, but when I declined the change they said the brake pads are so bad that I may not be able to leave the service center. With that kind of fear tactics you really don't have much of a choice.
