PURCHASED TRUCK 11/10/2011 WITH 3 MILES ON IT. AT 4,000 MILES THE TRUCKS BRAKES STARTED PULSATING AND SHIMMING WHILE APPLING BRAKES GOING DOWN HILL. TOOK IT TO DEALER , THEY RESURFACED FRONT ROTORS. GOOD TILL 5,700 MILES AND IT STARTED DOING THIS AGAIN, BUT WORSE, ALSO PROBLEMS JUST BRAKING ANY WHERE. TOOK BACK TO DEALER, NOW THEY RESURFACED REAR DRUMS. I'M VERY DISAPPOINTED IN THIS NEW VEHICLE'S BRAKING SYSTEM. THEY WROTE THE BRAKES WERE WARPED DURING BOTH VISITS, AND NO REASON AS TO WHY THIS IS HAPPENING TO MY NEW VEHICLE. *TT
