My car shut off/the engine lost power, while sitting in traffic. I felt a slight rough idle, then realized all my dash lights were on, and the engine was not running. I placed the car in park, and pushed the engine start button. Car started back up, but every time I stopped I had to place the car in park and keep my foot slightly on the gas to keep it from idling roughly and shutting off again. I had to do this for a half hour until I reached my destination. After setting for 4 hours the car started fine and I had not further issues. But my fear is that it will happen again while in traffic or possibly while driving, which could cause an accident.

Engine just shuts off while driving. It becomes difficult to steer and control. I was barely able to move to the side of the street and the car behind me almost ran into me because of my loss of power. There are no warning lights and the radio, etc. All stayed on during this event. I had to put the car in park and restart the engine.

For the fifth time I am having an oxygen sensor replaced on my genesis (the vehicle has 4). The symptom has been a "check engine light" that results in an intermittent, occasional problem when stopped and idling. The engine light starts to flash, the engine begins to idle very roughly, and there's barely enough power to creep through the intersection. This condition clears up pretty quickly but the light remains on. The flashing light/rough idle/loss of power recurs. The problem has occurred requiring an oxygen sensor change five times starting in mid-2016 at around 100,000 miles.

I was coming to a stop in traffic, the engine RPM was dropping, and wanted to change lanes. Upon accelerating I attempted to turn the steering wheel and I lost power steering, almost collided with other vehicles and was close to being hit by oncoming traffic. This has happened many times with this vehicle. I am speaking out now because I have seen the federal safety agency campaign number: 15v100000 and it sounds like what my vehicle does.

The car had recently gotten a major service at the dealership in early august. The car had not been driven much since that service as the primary driver was unable to drive the car from mid august through the time of the incident. This is a car that was well maintained through dealership servicing. The car was being driven on the freeway at night at the approximate speed of 65 MPH. Suddenly, a loud metallic clank, clank clank came from underneath the car. It sounded as if we had run over something on the freeway. Directly following this, the car lost all power and we noticed the smell of electrical burning. We were unable to accelerate and the headlights began to dim. Luckily, we were able to steer the car off the next off ramp & bring the car to a stop but the power steering and power braking were gone. Had this not occurred on a sunday night, the results could have been very different. Once safely to the side of , we smelled a strong electrical burning smell in the passenger compartment. We did not witness evidence of fire or smoke. Initially, the lights went out completely. They slowly powered back on but each time keyless start button was pushed, the lights would begin to dim again. The car was towed to the dealership. The dealership called the following day to let us know that the engine had a hole in the block. From their assessment, this was not caused by an external force but from the failure of an internal component. We filed a claim with hyundai corporate who deemed that the problem was not caused by a manufacturer's defect.

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.

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.
