Hyundai sonota 2002 had front rotors replaced at 10,500 miles due to warping. Front pads were in excellent condition. At 43,500, was told by dealership all 4 rotors were warped during state inspection. So, only 33,000 miles on new front rotors. Both front and rear brake pads were still in excellent condition (virtiually new). This documented on the cars state inspection report done by the dealership. Dealership contacted local Hyundai rep who refused to replace rotors. Reason, excessive braking by driver so not faulty materials from Hyundai. Two reports don't coincide. Excessive braking and excellent brake pasds. Local rep did not come into dealership to view condition of car or do any investigating into potential faulty manufacturing materials. Owner filed a complaint with Hyundai Consumer Affairs. Credit the dealership for complimentary cutting of rotors but history shows rotors will warp again after cutting.
