On or about 8-9-10, we felt a shuddering feeling in our vehicle. We took the vehicle to a GM dealer and they stated the brakes needed to have the rotors turned. GM dealer completed repairs and on or about may of 2011, vehicle began to shudder again. We took the vehicle back to the same GM dealer and the rotors were bad again. The dealer stated that the rotors had been turned improperly back in August 2010. They returned the rotors and told us it was an engineering defect and that we would have to come back every year to have our brakes repaired and they would take responsibility. On or about 8-5-11, the vehicle began to shudder once again. On 8-9-11, we returned the vehicle to the same GM dealer and advised them it was shuddering again. The service representative advised that we would have to replace the rotors and it would cost us as it is not covered under warranty. We informed him of the prior visits and he was not forthright that he knew of our vehicle. I advised him that I was told by the service manager that the rotors were repaired improperly and he acknowledged it was a bad machine and they have a new one now. He said it was due to our driving habits and was not a warranty item as it is normal wear and tear. He then attempted to change the conversation by getting us to perform recommended maintenance on the transmission, fuel injectors, and differential. These services were not even required by the owners manual until at least 100,000 miles and this vehicle only has 30,000 miles currently. We changed the conversation back to the issue at hand (the brakes) and he said he would inspect and advise and document to the service manager.
