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.
Uncontrolled acceleration incident report incident occurred at 5:05 pm friday november 19, 2010 vehicle: 2007 hyundai sonata from about 50 MPH, I changed lanes and accelerated into the lane's traffic by pressing the gas pedal as far as it would go. When I partially let up on the gas pedal, the car kept accelerating, with the engine roaring, and I fought it with the brake. I put it into neutral and the engine roared still more loudly, so I put it back into drive and used the brake more while the engine roared at its previous rate, which I saw on the tachometer was about 3000 RPM. Then after around five seconds more I put it in neutral again; this time it died down to normal RPM, and I coasted to a stop. After about twenty seconds I put it back into drive, and it was fine. At first I wondered whether the accelerator had gotten caught on the store-bought floor mat, so when I got home I experimented with it, never having moved the mat from its position during the incident. I could indeed cause the lower end of the accelerator to go under the forward edge of the mat, but the mat was not attached to the floor and was too light to prevent the accelerator from coming back up immediately. When I did the same mat experiment on november 22 in the presence of the local hyundai service manager, she agreed that it is very unlikely that the mat was the problem. She had her technician check the car electronically, but no codes came up to indicate a problem. The service department then did a 'premium fuel service fuel injector / throttle body service' and a 'complete 27 point inspection'.
Upon startup, the check engine light illuminated. Car was put into gear, but accelerator pedal had no effect; car was in "limp" mode. Turned car off and restarted several times before it went back to "normal" mode. Check engine light turned off. Took to dealership and was informed that this was their number one problem/complaint. Service manager at tuscaloosa hyundai said they replace the $500+ throttle positioning sensor on 4-5 cars per week. He said hyundai wouldn't issue a recall until someone got hurt. I called hyundai customer service to complain that this sounds like a major problem that should warrant a recall. Agent claimed there were no problems; that mine was an isolated incident. Called manager back, and he said that a hyundai representative had talked to him about the wide-spread problem. I believe that hyundai should pay for this repair, as it seems it is widespread, and perhaps being covered up or hidden.

On 3/3/08 I was returning home from picking up my daughter from school. I made a left hand turn onto jones chapel road and when I went to accelerate the car full throttled on it's own. I tried mashing the brakes and it only slowed my car by 10 miles an hour or so. I finally put the car in neutral(the engine continued to rev very high) and shut my car off. I had roadside tow it and it is still at the dealership. They have been unable to duplicate the problem. There was nothing in the floor board and my car floor mat is secured by a peg. When the car took off it literally jerked mine and my daughter's heads back.
