Hi All, Amye here. I just joined and am quite shy about it. Putting myself out there cuz I have some questions about my 2009 cayenne . Purchased her new from an excellent dealership, I was a queen there! Few years later, sold to Penske and have little faith in the shop honesty. She is now 5 years old and still a new car. 37000 miles. Went to the shop at 15000 miles or so and left with new front brake pads and a $500 oil change. No pad light came on as warning. Presently buying 4 tires , service and rear brakes probably rotors also ( does anybody machine anymore?) Everything is quoted $1400, so that adds up to $4200! They said spark plugs should be changed also..Really, are you kidding me??? I would love some opinions.
