Brake Disc Pads problems of the 2007 Chevrolet Cobalt

This regards a chevy Cobalt ss. This vehicle is mostly driven on city streets and occasional long freeway trips, no towing or overloading. Noticed at somewhere around 10,000-15,000 miles (maybe sooner. ) that rear brakes were very noisy when backing. Loud enough that the neighbors could hear them in the morning when I backed out of the garage. Easily be heard down the street. The brakes had always been noisier than I would expect for a new vehicle. Finally got tired of noise at 17,000 miles and took car to dealer. (03/03/08. ) they advised that there was nothing wrong with brakes, inspection report from jack maxton chevy states that front and rear linings have the appropriate thickness in mm. They applied "anti-squeak" to the brakes. As time passed the brakes returned to their noisy state. Time for a 30,000 mile checkup so we took the car in and asked them to check the brakes again. They advised us that we needed new rotors and brake pads. They said it would cost over $400, we didn't want to pay that much at the time so they turned the rotors, installed new brake pads, costing over $200. The new brake pads squeak and squeal, took the car back in, they looked at it again, service rep advised that the new pads would sound that way while they broke in. I never had new brake pads make noises after having them installed on other vehicles in the past. They sent us a survey to complete. (they're always very concerned about these. ) we reported all of this on the survey and all we ever received in response was a phone call advising us that we were going to receive a survey. (we received a call with the same advice prior to the survey too. ) to add injury to insult, we purchased an extended, 7-year bumper-to-bumper warranty when we bought this vehicle. At the time we were told it would cover everything on the car, no matter what went wrong with it. We had been chevy fans for years and a few vehicles. We'll look at foreign cars next time.

I have a 2007 Chevrolet Cobalt and at approximately 15,000 miles began having some slight vibrations when braking. I went to have the brakes checked to make sure everything was okay and was told that my brake pads were good. I drove more until approximately 20,000 miles and the vibrations increased. I finally ended up getting it into the dealership at 26000 and they told me my rotors were warped and they resurfaced them and they were fixed. Now only an additional 15000 miles and the vibration is back but even worse. I believe they just resurfaced them knowing that they are malfunctioning so that when it happened again they were not covered under warranty. When I contacted the dealership back to inform them that they are not fixed they informed me that it was my own maintenance problem even though they are obviously defective. I am at a loss as new rotors will surely find the same fate and it is very expensive to replace rotors every 15,000 - 20,000 miles. I have never owned a vehicle that I even had to have rotors resurfaced or replaced with regular maintenance. Very disappointed and upset that this is not being researched and recalled by Chevrolet as a defect and safety issue.
