Car Accelerates On Its Own problems of the 2007 Hyundai Sonata

The contact owns a 2007 Hyundai Sonata. The contact was driving 5 mph when the brakes were depressed and the vehicle accelerated unexpectedly, crashing into a wall. The crash caused the air bags to deploy. The contact and passenger suffered injuries to their chest areas as a result of the crash. The police were notified and a report was on file. The vehicle was then towed to a local repair shop. The manufacturer was notified. The vehicle was not repaired. The failure and current mileages were 78,060. Updated 06/05/lj updated 06/06/12 the consumer stated as the brake was applied to enter a parking space, the vehicle suddenly accelerated, and went over a curb, three feet of lawn and hit a stone wall. The vehicle was not repaired and deemed totaled. Updated 06/19/12.

While operating my 2007 Hyundai Sonata, I experienced sudden unintended acceleration (sua) whcih 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 foor 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 consiliatory 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 lanes 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.

The contact owns a 2007 Hyundai Sonata. The contact stated while sitting idle at a traffic stop behind a truck, there was an unusual increase in engine rpms. The vehicle suddenly accelerated into the rear of the truck. The vehicle was towed to the dealer yet the dealer was unable to duplicate the failure. The dealer also advised that if the failure were to occur again, that the contact should put the vehicle into neutral to stop the unintended acceleration. The failure occurred again and the contact was able to stop the acceleration by following the dealers advice. The failure mileage was 2,000 and the current mileage was 13,000.
