The vehicle started accelerating while stopped at a traffic light. The brakes had to be applied harder and harder to keep it from going into the intersection, the brakes were applied so hard that the back wheels were spinning. A warning was flashed on the dash but went off immediately all that was seen was an "a", at that point the auto stop/start button was disengaged and the acceleration stopped. The vehicle was on a city street in downtown orlando.
