While operating my 2007 hyundai sonata, I experienced sudden unintended acceleration (sua) which resulted in an accident of moderate property damage and no injuries. I had pulled to a curbside to park, and had stopped approximately 8 feet behind a large SUV. As I began to raise my foot off the gas pedal, the engine started to accelerate. I applied the brakes which initially began to hold the car which was starting to move forward, but as the acceleration increased, the brakes became unable to hold the car, and it lurched forward and struck the unoccupied SUV. Even though my car only accelerated and traveled 8 feet, the impact was strong enough to cause $6000 worth of damage (actual allowance by insurance company). I've since found out that the hydraulic breaking system and the electronic throttling system are inversely connected to the vacuum generated by the car's engine which means that braking power decreases as throttle increases. Cause of the sua has not been determined. After I got the car repaired, I took it to hyundai and they were very conciliatory but after checking it for an hour, state that they were unable to recreate the condition and that they did a complete safety check and scanned all the electronic systems to no avail. I had never experienced this condition in the past in this vehicle, however, I had experienced it 3 times in my wife's 2003 hyundai sante fe. In those situations, there was not anything directly in front of me, and I was able to shift into neutral and regain control of the vehicle.
