Has anyone experienced problems with brakes and rotors. I purchased the car approx 5 years ago with approx 36K miles. Within the first year, during routine maintenance check, I was advised the front rotors needed replaced. The new rotors were turned approx 1 year later. At 82K miles, I was advised the front rotors need replacement again. Rotors were replaced at 45K miles and 82K miles. I'm beginning to see a pattern that the dealer said is unusual. Has anyone had similar problems? If not replaced, there is shaking/pulsing in steering wheel when braking. Thanks.
