Gasoline Engine Problems of Hyundai Sonata

The engine will intermittently race increasing rpms without notice, very dangerous. It happened while sitting at a red light. If my foot was not pushed down on the brake I would have hit the car in front, it will also occur while in park with the engine rpms going up to 3200 and down to 1500 like it was a hunt lasting several minutes. It will stop ,but I can't figure out how or why. It seems to be worse when driving at sustained higher speeds on interstate, then getting off the exit. I do notice that when I accelerate away from a light while the prms are high the engine almost cuts off then picks up in a jerking motion. If I turn off the engine while the rpms are high racing I am not able to restart for a while. I smell gas, flooding I assume. The repair shop has not been able to correct it since it does not happen while in their hands.

Vehicle is very dangerous - manufacturer needs to take steps in ensuring my safety as well as the safety of others on the road.

Engine losses power and sometimes stops. Difficulty turning on power.

I bought this car mid-April of this year, had it two weeks and get cut off in the middle of the road. My children and I could have been hurt because of this. Since then, the car has cut off a total of eight times and it's only been a month that I have had this car. I have taken the car back for service a total of 3 times and the mechanics are saying that the computer isn't reading any problems. They have had my car all week to try to duplicate the problem. They are saying that they must duplicate the problem to diagnose a remedy. I have been inconvienced and disappointed in all aspects of this situation. What were they doing to diagnose problems before computers were invented? I believe that they (the mechanics) need to go back to that long lost skill to remedy the problem and fix my car. I am totally disgusted in this whole matter.

Vehicle has been back to auto repair center for the same reoccurring problem at least 10 different times. Car cuts off at cruise speeds car/ bucks and restarts, car dies when you turn corners at low speeds and you must put car in nutrel to restart.

When slowing down and coming to a stop consumer would think that vehicle was at a complete stop, but vehicle would jump or lurch forward. Also, when vehicle downshifted from 25 mph to 20 mph consumer would feel that vehicle kicked or pulsed. Dealer claimed it was a normal characteristic of vehicle.

Consumer contacted dealer in reference to recall 00v259001/manufacturer's recall 039. Dealer lcorrected recall problems. But, while driving at any speed and without prior warning vehicle cut off, causing loss of all power. Please provide any further details.
