Braking from highway speeds 70 down to 50 results in serious vibration and pulsation due to out of round disc brake rotors. Feels like possible loss of braking control. Problem has existed since vehicle was new and corrected only by machining the front brake rotors. Original rotors machined 3 times in 65000 miles. Original rotors recently replaced with new oem parts and problem occured again within 5k miles. Complained to dealer and Hyundai regional manager. Explanation was that rotors are not defective if out of round and condition can be corrected by machining. Appears rotors are unable to withstand braking temperatures and warp as result. Quality of steel material used in manufacturing the rotors appears poor. Hyundai does not seem to acknowledge problem with flaw in manufacturing process.
The brake rotor overheated, which caused a grinding noise when the brakes were applied. Dealer is aware of the problem. Mr.
