While making a right turn onto ramp engine falls cuts off and I have no control over steering, breaks or anything. Finally got it on to the side of road and put it in park and it cracked right up. This is very scary. What if I had been going fast down the road and could not stop the car. Someone could be killed like this. I decided to look it up on google and found out that lots of other have had the same identical problems and no mechanic or anyone can find anything. Hyundai needs to be held accountable for this and fix there miss up but of course it will take people being killed first.

Every time my car is idle, whether at carport, street light or heavy traffic, the engine runs really rough sounds/feels like it is going to turn off (stop running)also when ac/heater & radio are on it gets worse! it's scary to think I may get stuck in middle of freeway/street every time car is at idle. I've taken it to Hyundai dealer from day one for the issue and even let them know it's still happening every time I take it for engine oil change or other scheduled maintenance and told every time they can't find issue!! I do not remember specific dates, nor did I save all the paper work since I bought the car in 2012! shouldn't dealer have records in their computers? it's been on going since I bought the car in 2012!!

I have a serious issue with my 2012 Hyundai Genesis 5.0 R-spec. I have an ongoing exhaust smell/leak. It is very strong when starting the vehicle and at idle, especially when stopped at a red light. The smell seems to be either raw fuel or raw exhaust that is leaking from somewhere in the system. I have to place my ac system on recirculate or lower a window or the fumes become overwhelming. Once the vehicle is moving the smell subsides. On 01/18/2017 my local dealership preformed an evap service to possibly fix this issue to no avail. A second evap and ac system service on 02/01/17 was preformed and still the problem continues. The dealership says the charcoal fuel tank filter is fine and could not find any leaks in the exhaust system. I believe the smell is coming from the front of the car possibly the exhaust manifold of from the fuel system pluming. The car uses direct injection which is under very high pressure when working. I am worried that to much carbon monoxide could possible build up inside the car and cause an adverse health and safety issue.

Engine shutdown and lost steering and brake control when making a right turn. This is the 2nd time this has happened. Details: On both the times, when I was trying to make a right turn at a slow speed the engine shut down and I lost control of steering was well as brakes. I had to put the car in park, in the middle of the intersection and push button to start the car again. Luckily there was nothing in the way (car or a pedestrian), or else there would have been an accident. This could be an even dangerous issue if this happens when making a left turn or when on a freeway. Please issue a recall for this, and have Hyundai fix this problem.

While driving straight on a level city street at night at about 30 mph, without notice or hesitation, the engine completely quit/shut down--no power brakes or steering. I pulled over and the car coasted to a stop. All the lights went on on the dash and headlights stayed on, so there was battery power available. I placed the car in park and it restarted and drove normally. However, this has now happened three times now in last 6 months without warning.--very dangerous.

This has been an ongoing issue, I know others have reported a similar problem. When coming to a stop in our 2012 Genesis 3.8L the engine will shut off without any warning. This has happened more than a dozen times at this point. My wife took it to the dealer who said this issue couldn't be duplicated. The car has died in traffic and when going around a curve. Power steering is lost when this occurs making it a bit nerve wracking. This is an issue Hyundai needs to address before someone is injured or worse.
