Brake Disc Pads problems of the 2006 Mazda MAZDA6

Brakes have failed 3 separate times in this 2006 Mazda 6. First time I was driving and went through a stop sign. I have the brake pedal to the floor. Pumped the brake and brakes came back on. Second time, backing out of garage no brakes. Had pedal to floor and had to pump them before almost hitting neighbors garage, last time pulled into a parking spot and had no brakes. Hit another car which stopped me. Each time I reported this to polar chevy/Mazda. Each time they had me bring in the car and they looked at it. Each time they reported nothing wrong with the car. Each time they stated that there was nothing wrong with the car and that I needed to have the back brake pads replaced. The last time the brakes failed polar chevy/Mazda called a tech at Mazda. I was told they have never heard of this doing this before. I have told them now 3 times and again each time the car has been brought into be looked at!.

I purchased a 2006 Mazda 6 isport in Dec 2005. Since purchase I have had aggressive vibrations in the brake system every 15,000-20,000 miles. While I am a high mileage driver, most driving is on a highway and does not requires start-stop braking. In addition, I have replaced my brake pads when tech's have suggested. I have my rotors turned out by the Mazda dealers 3 times and in the current situation the rotor cannot be turned. The dealer and the Mazda corporate refuse to look into my history of this issue because my car is out of warranty. After much research, I have found several dozen Mazda forums that discuss this same issue with the Mazda 6. I have also found that the government found issues with former Mazda vehicles such as the tribute and its Ford counterpart. This is obviously a problem however the dealers, Mazda's local technician, and the corporate tech line will refuse to look into the matter anymore.
