2009 Hyundai Genesis: check engine light

Filed Mar 14, 2024 · Engine · IL

While driving the vehicle with approximately 113,200 miles on it, as the original owner, the car engine started to operate erratically. then the check engine light came on and then the check oil light came on and, after a short period of driving, the car stalled out and would not start up. This stalling out happened in a left turn lane of a very busy road. Two men in a vehicle that stopped behind me got out and pushed me off of the roadway about a block away from a dealer. The car was manually pushed into the dealership. The mechanic checked and the oil was full. The car is available, in my garage, for inspection upon request. The number 1 cylinder valve spring was broken and the engine jumped the timing on both sides with $2792.53 to $7,086.78 for parts plus labor to repair. At 86,283 miles, while driving in my village the number 3 intake valve spring broke and was repaired. At 51,574 miles, while driving on the interstate, the number 7 exhaust valve spring broke and was repaired. All three times the vehicle operated erratically. The car was in traffic each time this occurred and my safety and the safety of others were put at risk. I have all the receipts from all three breakdowns including the diagnosis. The engine is apart now and I have the parts list and labor costs from the dealership for the work that needs to be done. Initially I was told by the dealer that I needed to have all 32 valve springs and rocker arm assemblies replaced according to a Technical Service Bulletin. When I protested that they did not do that during the previous repairs the dealer said they would only replace the one that was damaged. That is why there are two parts estimates. I have them both. The check engine light came on just after the engine started to operate erratically and the check oil light came on shortly thereafter. I contacted the manufacturer and they said they could do nothing.

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 driving from rhode island to north carolina and when I was driving west across the tappan zee bridge near new york city and had gotten to the other side of the bridge, I lost throttle response. The car began to slow down in heavy traffic and I had to cross three lanes to get to the right hand lane. The check engine light was on steady at this point. By the time I reached the right hand lane, the car was going only about 35 MPH and I was very lucky that I was not hit by other vehicles on the bridge, who were dodging me at high speed on both sides. . This was a very scary situation and could easily have resulted in fatalities. Fortunately, there was an exit on the other side of the bridge and I managed to get off i287 and find a place to stop. I checked the internet and found reports that other people had experienced similar events and that the car returned to normal after turning off the engine and restarting it. My wife, who was with me, recalled that something similar happened to her 2004 hyundai santa fe several years ago when it was driven locally by one of my sons. So after about 20 minutes, I restarted the car and found that throttle control had returned and we continued on our way. After stopping to eat later in the day, and returning to the car, the check engine light had gone off and has been off ever since. I managed to return to rhode island yesterday without any further problems, but am now afraid that this might happen again and that I will not be so lucky the next time. I have not had time yet to have the dealer check out the car, but plan to do so as soon as possible. This is clearly a serious safety issue and I am surprised that there has not been a recall to fix this problem, especially considering that it appears to be something that has been happening to hyundai cars, (and possibly others), for some time now.

While driving at 65 MPH in 4 lane I-95 rush hour traffic, the check engine light and the ESC light both came on and the car would not accelerate. Pressing on the gas pedal had no effect. I turned on flashers and drifted my way through 3 lanes and pulled over and restarted the car. The check engine light came on but not the ESC light. The car ran a bit rough with the check engine light on. The exact same thing happened the next day. I took the car to the dealer, and they replaced the throttle position sensor. Based on owner reports at the genesis owners web site, this has happened to many owners of 2009 v6 hyundai genesis. This is very dangerous, and the car should be recalled to fix this potential deadly situation. If I had been driving in the left lane of a highway, a serious accident with potential deaths could have happened. I had to pay 325 dollars to have this issue fixed since it has not been recalled. Please work with hyundai to ensure this major safety issue is recalled urgently.

Driving on the freeway and the throttle just cuts off, no throttle power. Car is still running. Quickly had to pull over on to the side of the road and had to shut car off and then restarted it. It worked but it continues to happen. It happened seven times in one day, with my child in the car. At one point there wasn't a shoulder to pull over to I had to stop in the middle of the freeway. Hyundai has no recall for this issue. I find that strange since this could be a serious issue. The ESC and check engine light comes on.

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.

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.
