Every time if you ask for some simple maintenance, like oil change or tire rotation, they can always find some problem on your car. Then you have to spend hundreds of dollars. They will say "we provide more service to get you a safer car". But if it's every time, the feeling is really bad. And I doubt if all the recommendations are really necessary. I replaced the air filters for engine and cabin the day before I did oil change. And they recommended to replace the filters.
