It's termed as a "Dead Pedal" with the accelerator pedal sensor as to when the accelerator pedal is applied to move the car, the signal to apply gas to the engine to move it, doe's not happen, and the car will not move, momentarily causing a very unsafe situation in traffic. this problem is sporadic and you never know when it will happen. to my knowledge this is happening in the 2009 to 2015 models Hyundai Genesis cars with the 3.8 and 4.6 and 5.0 engines. Any car with the drive by wire is effected with this problem, and should be looked into and repaired. I have not gone to the dealer with this problem and there is no check engine light on when it happens.

Car engine shuts off/stops running, without warning, while driving. Has happened 3 times in the past 12 months. At slower speed, in town, coming to a stop or slowing for a turn. Car starts back up right away, and won't stop again for a long time. Also can't make it stop on purpose.

- Bessemer, AL, USA

I was driving on a highway when my vehicle stalled nearly causing a major accident. There was no warning, engine light or issues with the car starting or driving. No issues with idling or anything to suggest I needed service. The dealer is saying it is excess carbon on the throttle body. It appears Hyundai has had issues with this that have not been addressed.
