Problems with 2009 Hyundai Genesis ENGINE AND ENGINE COOLING

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. http://www.genesisowners.com/hyundai-genesis-forum/showthread.php?t=4459.

I was driving my 2009 hyundai genesis 3.8 v6 sedan on georgia 400 north (north of atlanta, ga) on monday, july 12 when the gas pedal didn't respond as i depressed it. after that when i pressed on the accelerator, there was no power.gas pedal was intermittent in it's response initially. 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. the car would start but wouldn't stay powered so i had to call hyundai roadside assistance for a tow. towed to local dealership in roswell. put it on the computer to check codes but didn't find anything. local dealership kept car 2 days, called hyundai corporate, and was told to flash the computer. dealership took for a couple of test drives but problem didn't re occur. genesis owners forum has a similar occurance listed. very concerned about a possible reoccurance that may not have such a pleasant outcome if i lose power again. *tr
