Traveling to indiana from north carolina on the 6th of may 2011. On a rural road traveling approximately 55 MPH, all of a sudden the engine light and ESC warning lights came on. After that when I pressed on the accelerator, there was no power. Electricity was still there and the engine was still on, but no power from the gas pedal. I had to turn the emergency lights on and moved onto the side. I was lucky because there weren't many cars around. It would have been pretty dangerous if there were cars around and my car suddenly stopped. I was able to turn the car off and restart. When I restarted the car the engine light remained on but I had regain the ability to accelerate. I pulled into a hotel and called hyundai. The closest dealer was gaddis hyundai of muncie, indiana. The service department was closing but I discussed with technician. He indicated that it was common problem with the throttle sensor. He indicated that he would be able to fix it monday, but that if the light went off and it was running ok, it may never happen again. I told him that I need to be durham , nc on monday. He indicated that if it happen again. To turn off and restart and it should reset. On my way back from indiana to north carolina I stayed in the right hand lane. On 4 separate occasions the vehicle lost power and I was unable to accelerate. Each time I was able to pull over to the side of the road, turn the vehicle off, wait a few minutes and then restart and continue. The car is currently at the stevenson hyundai dealership in jacksonville, nc. Here is a forum web site that reflects similar problem identified on numerous occasions related to the hyundai genesis v6 and v8.

2009 Hyundai Genesis acceleration complaints
Page 2 of 2: complaints 11 to 16 of 16, newest first, as owners wrote them.
While the vehicle was idling or in low RPM it would start to sputter as if it was going to stall. I returned the vehicle to the dealer and it was a fault throttle sensor.
Tl*the contact owns a 2009 hyundai genesis. While the contact was driving approximately 65 MPH, the engine lost power on a four lane highway. The engine would not restart. The vehicle was towed to an authorized dealer where they informed the contact that the failure was attributed to a defective throttle sensor. The vehicle was repaired. The failure mileage was 16,080. Updated 11/12/10 updated 01/06/11*lj the consumer stated the throttle became stuck at the idle level. Updated 03/02/11
Lost complete ability to accelerate on highway traveling at 70 MPH. No warning, happened twice more before I got it back to a dealer. Car did not shut off but would not accelerate. Restarted after I managed to get off in the breakdown lane. The car would go another few miles and konk out again. I immediately went to the closest hyundai dealer. They said it was a throttle position sensor. Could really have been fatal.
While driving the car, the engine loses power. Engine and electrical systems still running but when pushing the accelerator, you get no response. This has happened twice within the last 5 days. We have called and setup an appointment with the dealership, but the earliest appointment was this friday. Luckily we were not in heavy traffic or a serious accident could of occurred.
When I was trying to enter an expressway from an entry ramp, I stepped on the gas and got no response. The engine did not rev up as it would if the car was in neutral. I coasted to the apron , turned off the car, and restarted it. The gas responded normally after restarting but the engine light stayed on. I took it into the dealer and they reprogrammed the engine control unit, which, so far, has fixed the problem. I was told that the computer just lost track of the accelerator position. While this is not quite as dangerous as toyota's problem, it could still get someone killed if they are trying to pull out in traffic and gets no gas response. On the genesis owners forum there are at least 2 other similar incidents that have been reported. I wrote to hyundai to report this issue and they responded that they would log this incident. However I do not know when they send info to the federal safety agency.
