i recently purchased a used 2002 sonata with approx 55,000 miles on it. the back and front brake pads and back rotors needed to be replacedwithin the first 200 miles that i drove the car. the shady dealership that i purchased the car from did (very reluctantly) pay for most of the work done. now, less than 3000 miles later, the check engine lite is on and i'm told that the back rotors are shot again. does this problem sound familiar? should i try to get rid of the car? i told the mechanic not to replace the rotors and i'm getting a second opinion but is this characteristic of this car or what? any advice is appreciated.
