“I was on my way to work when the truck in front of me stopped in front of me to let a car in our lane. We were going around 15 MPH. When I stepped on the brake, I just kept on going and hit the truck in the rear. I put the car in park and got out and went over to the driver of the truck to make sure he was ok. He told me he was fine,at which point I told him the damage done was to my car and his truck was fine. He said fine and went on his way. I got back in my car and found my brake peddle had broken off the arm and was on the floor. The metal part of peddle snapped right off the brake arm.”

“Consumer has experienced problem with intermittent brake failure. When brakes applied vehicle would keep on going. Also, intermittently park lights and ABS lights would come on, and all brakes would fail to stop vehicle. Dealer notified.”

“Anti-lock brakes and brake system warning lights on dashboard come on. When consumer attempts to slow/stop vehicle, there is no resistance behind the brake pedal, and it goes to the floor. This has occurred three times; at 15-20 MPH range/ 20-30 MPH range, and at 40-50 MPH range. A private mechanic stated that on a previous vehicle with same defect occurred. They ran a diagnostic on brake system and found no defects, but replaced brake system which repaired defect. Consumer has not determined whether or not he will have this done.”
