Sonata 4-cyl

Unintended acceleration, had to slam on brakes and put car into neutral in order to prevent shooting into a intersection of oncoming traffic. The car immediately threw a number of codes, and a engine control system condition code, check engine code.... dealer tells me when unloaded off the tow-truck that the brake pedal went to the floor, after 6 days of having the car the dealership service manager is telling me no problem could be found due to not being able to reproduce the problem.

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.

Car lost anti-lock brakes and electronic stability control functions. This was caused by the drivers front wheel sensor wire rubbing against a sharp sheet metal edge. See photos.
