This car is expensive to maintain
I was having a problem with the brakes pulsing (what many would call warped rotors). Had the problem ever since I bought the car. It felt like it was the fronts, so I had replaced everything but the calipers earlier this year, but the problem came back. I hadn't looked at the rears, but with the problem back, I had a shop look at them and he said the rear rotors were completely gone; could not be turned. So, that was obviously the problem. OEM rotors and some nice pads cost me almost $400! Plus I had to do part of the 120K service also, as I had already done most of the other things this year. That wasn't cheap either...
On the positive side, the brakes feel great now.
