Why so cryptic?? How many miles or km do you have on it? Is the only issue that the brakes are scored? Are they scored in a circular ring pattern? If you car is 3 years old and has high miles, you may simply need new rotors.. or you have badly worn pads and have been using them long enough to score the brakes. Probably not something you could expect a warranty to cover after the 12000mi adjustment period.
I doubt it will be a warranty replacement as brakes are wear items. It is normal that the hand brake releases with a "crack" when the car has been sitting especially with moisture.
