Check Engine Light On problems of the 2009 Hyundai Genesis

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.

The contact owns a 2009 Hyundai Genesis. The contact stated that when the vehicle was started, the check engine warning light illuminated. The vehicle was taken to a dealer, where it was diagnosed that the sensor assembly oxygen sensor needed to be replaced. The vehicle was repaired however, the failure recurred. The manufacturer was notified of the failure. The failure mileage was 73,199.

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. . Read more...
