Stalled twice on the same day - stalled when braking at low speed on a city street prior to a complete stop. Shifted to neutral and tried to start car. Car was trying to start but hesitated. Gave it a hard acceleration, it then ran normal. Second incident on the same trip. - stalled on city street when braking at low speed. Shifted to neutral and started car. Gave it a hard acceleration, it then ran normal. Side note: - could not start after stopped at gas station for refuel (when pushing the start button, it only had the tick, tick, tick noise.) had to give hard acceleration to get the engine running. Idle was very rough and unstable. Gave hard acceleration to blow out carbon and idle went back to normal. - believe wife took the car to dealer a few days or a week later for diagnostic but no error codes or cause was found. Needed to locate receipt to confirm. - this is at least the eighth time it happened. Previous filed odi number 10606872, 10746269, 11221909 and 11221913. - weather condition: above 75 degrees

While rolling slowly, then accelerating to cross 3 lanes of traffic, mainly in local town driving, the car seems to stall and then suddenly accelerated very quickly. This has happened at least 10 times in different situations I.e.: changing lanes quickly after rolling, while waiting for an opening in traffic. Have brought car back to dealer many times with the same complaint. Once they said they updated the transmission. It did not help. The last time they said don't use the eco mode, it creates a slight hesitation. I'm afraid this car will kill me someday when I pull out into traffic and have be power

We were at an intersection on highway 1. Cars were driving by at the speed limit of 55mph so it was important that we accelerate quickly in order to turn left onto the highway and avoid being hit by oncoming traffic. *tr when it was time to go I stepped on the accelerator, the car began to move and then we experienced engine hesitation, where there was a momentary period where the engine did not respond to me stepping on the accelerator. I reacted by stepping on the accelerator completely to the bottom and still had no response - we were coasting. I completely backed off the accelerator and stepped on it again when the engine finally began to respond. Vehicles were fast approaching and in that moment I felt scared and lost trust in my car's functionality. Earlier that day I also noticed that when accelerating, when already moving, I noticed that the transmission felt like it would wobble. It's difficult to describe. It felt like very subtle momentary losses of power or acceleration followed by a recovery in the acceleration and then repeating but in quick succession. You would only notice it if you owned the car. I have not been able to duplicate it. Maybe it was the traction control system but being unable to accelerate in a situation like mine was very dangerous.

While in traffic, stopped and attempting to change to next left hand lane, car stalls for a few seconds instead of accelerate, then it takes off after delay. The delay will cause an accident. Have mentioned this to the dealer and they do nothing. Dealer says everything is operating as designed. Posted this incident on genesis forum and have gotten numerous complaints describing the same problem as I have been experiencing. We have had the car now just over 1 year now and it still does the hesitation. This issue needs to be addressed before some one gets killed due to no accelerator response when in traffic. Other than this problem, we like the 2013 genesis very much.

Multiple times I have accelerated the car to get onto the highway, change lanes quickly,and make right on reds, only to have it literally do nothing. At times it takes 2 to 3 seconds before it accelerates and then seems to have a tough time shifting through the gears.at low speeds the car seems to hesitate and shift poorly. Hopefully the dealer can do something to correct the issue.

Vehicle hesitates when trying to accelerate in city & highway traffic. I have taken it to the dealer twice and it will be the third time tomorrow. They don't seem to have a solution and tell me that the vehicle is learning my driving habit's. (how funny). This is my 15th or so new high line vehicle. This hesitation is causing life threatening experiences. I almost got creamed, (hit) several times while trying to merge on the free way. I see I'm not the only one with this problem. We need help.

Auto hesitates when accelerated hard; it falls flat on its face when called on to perform. Not sure if it is engine or transmission (wrong gear). I consider this a safety issue because one cannot get out of the way of oncoming traffic. Typically, when attempting to exit a slow moving (30-40 MPH) traffic lane into fast lane, the car temporarily stalls putting driver at risk of being hit in rear. This almost always happens where car is moving as slow speed, but rarely from a dead stop.
