I was on the freeway and my car suddenly shut off completely.. engine, dashboard, lights EVERYTHING.. it was off for maybe 2 seconds and then the car Powered itself back up the car did not stop abruptly, so I was thankful for that. I didn-??t panic or pull the wheel. I just continue straight and then thankfully it cut back on and then I got off the freeway as I was driving down the street not going more than 1015 miles my car cut off on me again it did the same exact thing everything just went off and then it cut back on mid drive and I have a four year-old toddler and I have been scared out of my life. Something is clearly wrong I need help please, no one can tell me what the problem

Car randomly turns off while driving. Sometimes my car will go off. Most of the time it turns back on but that is dangerous.

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.

The contact owns a 2009 Hyundai Genesis. While the vehicle was stopped at a traffic light, the engine stalled without warning. The vehicle was able to restart. The failure occurred twice. The vehicle was taken to a local dealer (gosch Hyundai 100 carriage circle, hemet, ca, 92545), but the cause of the failure could not be determined. The vehicle was not repaired. The manufacturer was notified and advised the contact to schedule an appointment with the local dealer for diagnostic testing. The failure mileage was approximately 40,000. The VIN was not available.

Was driving car to meet my husband and when I turned the corner, he was frantically waving me to get out of the car because it was on fire, in the front under the driver's side bumper. I got out and saw flames shooting from under the bumper. With the fire department on the way, we made several attempts to put the fire out w/water to no avail. A nearby store owner came out with a fire extinguisher and was able to put the fire out. Once fire department arrived, he indicated that it appeared to be an electrical fire. Once they moved the car, my husband attempted to start it and it started billowing out smoke. At that point, the fire department ordered him to turn it off and have the car towed and to not drive the vehicle again

Had a similar problem earlier today while taking the car out to get dinner. As I was approaching the freeway exit my car suddenly stalled and the steering wheel seemed to stiffen and the navi screen went out then back on. I pulled over emergency lane and waited to see what would happen and music continued up again from the usb port but I couldn't change the song. On the navi screen where usb setting is saying " initialization failed". so I pulled the usb stick to reset it and got it to work. I was able to go to dinner then drive back home without incident. But later on that night I tried to start my car but as soon as I hit the start button everything died. No power to anything no alarm no use of keyless entry no power at all. Then I come back to the car a few hours later that night and open the trunk manually with the key to get something and as soon as I slam the trunk down all the power came back hids, brake lights, lexicon system music playing. Except when I try to turn on the engine with the start button it won't start. Then everything shuts off like before I'm at a loss. But eeriely I been having problems like the previous poster with topping of gas issues because the car doesn't know when to stop pumping gas sometimes when full and a few times the car spewed out some fuel. I'm not sure if that is related to my recent stall incident but I've plans to driving from san jose back home to los angeles tomorrow on labor day and I'm scared to. What if the car stalls on mountain freeway over pass and it stalls and lose steering and brakes. I don't know if the dealer is even open labor day. What should I do? help!

  • 119,000 miles
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.
