I was stopped in a left turn lane and I believe I was the 8th or 9th vehicle in line. I had my foot on the brake pedal and the pedal went to the floor! I turned my steering wheel to the left as far as I could, but I tapped the bumper of the vehicle in front of me. There were no injuries and very minor damage to the rear bumper of the vehicle in front of me, and very minor damage to my front bumper. No other vehicles were involved. I called the Hyundai dealership and told them that my brakes had failed and had caused an accident. I was told that it was probably not the brakes, but the master brake cylinder. I had the vehicle towed to the dealership (carl gregory Hyundai, at northlake, columbus, GA) this morning I called to check on the status of the vehicle and was told that they had driven the vehicle for 200 miles and could not reproduce the problem. I had already told them that I was stopped in a turn lane when the brakes failed!! I was told that the Hyundai representative told them to replace the master cylinder.
