On or about October 1, 2103, the emergency brake light on the dash came on as I started the car and backed out of the garage. I checked and rechecked the emergency brake to make sure it was off and the pedal was not depressed. Every other time or so, when we used the car, the emergency brake light would come on and we always double checked to ensure the brake pedal was off. On October 7, 2103, we went to the jenkins Hyundai dealership and after they checked the vehicle, they could find nothing wrong with the brakes or the computer. As we left the place, the brake light came on for the 20 mile trip home. The Hyundai warranty states that we should not drive the vehicle because the brakes could lock up and cause an accident. It is either a brake problem or a computer and I would prefer to have it fixed before it causes an accident.
