Anytime I have a car serviced by a car dealership, regardless of brand, I always anticipate they will recommend more work than I think is necessary. My favorite go-to response to the items I wish to decline is, "not at this time". This seems to effectively convey, 1) I've heard and acknowledge the recommendation, 2) I am open to acting upon it at some point in the future, and 3) I do not want to pursue it today.
If the dealership gave push-back.....say, insisting they needed to change rotors whenever changing pads......I would take my car to another shop for a second opinion. Fortunately, living in a huge metropolitan area, I have lots of options in this regard.....including many independent shops which are unlikely to push more work than is strictly required.
Of course, it helps that I have a lot of first-hand repair experience and knowledge to help guide me with these choices. Still, I find the process distasteful, though sometimes necessary.
