7 Service Brakes problem

Failure Date: 06/06/2008

I have purchased a new 2008 GMC Sierra 1500 pickup on March 1 2008 and currently has 10, 400 miles on the vehicle. I have pouncing and vibrating brakes and had them checked at a gm dealer in my town, the brake rotor have measurements of 1. 17 and 1. 16 left, it is recommended that rotors be replaced at a measurement of 1. 1. Vehicle iis not safe to operate with rotors in this condition and have to be manufactures defect to be in this condition already. The vehicle as at a registered gm dealership in ligonier PA but this dealer is a Buick and pontiac dealer and does not sell GMC trucks. GMC will not honor the warranty at this location and this results in my operating a vehicle that is not safe. This is a combination of gm arrogance in policy and the installment of inferior brake rotors to begin with.
