I BOUGHT A BRAND NEW IMPALA, YEAR 2008. AFTER APPROXIMATELY 10K MILES I EXPERIENCED A VIBRATION IN THE REAR WHEN BRAKING. WHEN I BROUGHT THE CAR TO RADLEY CHEVROLET IN FREDERICKSBURG, THEY TOLD ME THAT THE ROTORS WERE WARPED AND IT WAS MY FAULT AND NOT COVERED BY WARRANTY. THEY SAID THAT THE LUG NUT TORQUE WAS NOT CORRECT AND UNEVEN. I NEVER TOUCHED THE LUG NUTS OR ROTATED THE TIRES AS THE TORQUE ISSUE WAS REAR ONLY AND TREAD WEAR PROVED THERE HAD BEEN NO ROTATION. I WENT TO CHEVROLET CUSTOMER SERVICE WHO STATED THE RADLEY SERVICE MANAGER WAS SUCH A GREAT GUY AND HE BELIEVED THE SERVICE MANAGER. WHEN I EXPLAINED THAT THE TREAD WEAR PROVED THE TIRES WERE NOT ROTATED HE THEN TOLD ME THAT NOT ROTATING THE TIRES WAS A MAINTENANCE VIOLATION ALSO. I ASKED HIM THAT NOW YOU ARE CLAIMING THE UNEVEN TORQUE WAS DUE TO ME NOT ROTATING THE TIRES. I AM FRUSTRATED AS I AM RIGHT AND NEVER TOUCHED THOSE TIRES OR NUTS. I AM NOT EVEN SURE WHERE THE WRENCH IS. *TR
