Every-time I start driving, I can hear a grinding noise so I changed the front breaks and the noise never went away. Then out of know where the back breaks and rotors went out fixed them and noise is still there. I hear a small knocking and squealing and when I stop, I can hear a grinding. I haven't even had the car for a year yet. I can hear it whenever I'm driving.
We bought the car in September 2012. Within days, we started to notice rust spots on the body of the car that appeared to be coming from brake dust. We contacted the dealer and informed them of the issue, and our concern that it would damage the clear coat or paint. Dealer stated they could not do anything. We started to notice brake noise. May 16, 2013; at 6,400 miles, we took the car to the dealer for service, and again complained of grinding noise when braking; dealer inspected brakes and said everything was fine. August 9, 2013; 7,589 miles. Took car in to dealer for service, again complained about brake noise; dealer inspected brakes and said everything was fine. June 16, 2014; 16,176 miles. Took car in to dealer for service, again complained about brakes, dealer inspected brakes and said everything was fine. May 10, 2016; 37,247 miles. Heard severe grinding noise coming from brakes, took to dealer to inspect. I asked a mechanic to ride with me while I drove to make sure they heard the noise, and mechanic did hear it. Dealer kept car for 7 days, inspected brakes, and said could not replicate noise. August 31, 2016, 40,400 miles. Heard severe grinding noise on brakes again, took to dealer, again had dealer rep listen to noise. Dealer inspected the brakes, and stated there was severe wear on the inside brake pads, that had damaged the rotors to the point they had to be replaced. There was no warning that the brake pads were worn prematurely, and the dealer failed to identify the issue with braking system until it was too late, creating a safety hazard. There was a problem with the braking system from the beginning, and we documented it at the dealer, where we had all service done.

The vehicle was repaired, but the failure recurred. The manufacturer was not notified of the failure. The VIN was invalid. The failure mileage was 22,500.
