Car shuts off while driving for no reason. Happens last time on the beltway. No check engine light or warning that it will cut off. Doesn’t happen at the mechanics. No one knows why it happens. I see this is an ongoing issue for Genesis

Vehicle shuts off at red lights or when making very low speed turns. Indicator on dash shows 'KEY' symbol and sometimes battery symbol. I then have to shift to park or neutral to push button restart vehicle. Other times I'm parked with vehicle idling and it simply shuts off. This issue puts me at risk because it shuts off while driving on public roads with other vehicles. The repair shop can't find out why this is happening and the vehicle flashes no check engine light and there are no stored codes. This began a couple months after I had a new battery installed in the vehicle and put a new battery in the key fob. Vehicle now, no longer recognizes key fob. I have to manually insert key fob into a key fob slot inside vehicle in order to crank it. This seems to be an issue with the 2012 model Genesis, as I have read on several online forums of other owners experiencing the same problem.

While driving the car to work I noticed that the brakes suddenly went soft. The car would slow down when I hit the pedal but in order to stop the car I had to nearly press the brake pedal to the floor. Later in the same drive the brakes functioned normally. I didn't notice another problem with the brakes for at least a week until my daughter drove the car and nearly hit someone because the brakes did not stop as she expected. I noticed that if I pumped the brake pedal the pressure would return for a while but then it would go soft again once I drove it and the pedal is pressed. At the point the pressure would not return consistently and it was questionable if the car would stop I took it to the dealership. The service department informed me that the ABS module has failed and that it would be a matter of time before my brakes would totally fail. There was no indication of the ABS module failing. No ABS light; no brake light; no check engine light. For this to affect the safety system of the car I would expect there to be some type of indication of failure. The dealer informed me that the module is $2200 for replacement! The car is only 5 years old why would the ABS module fail in such a relatively new vehicle?

The car will not start when the temp outside is ~40 degrees f or lower outside. It will crank non stop (push button start) but won't ever start. Car battery is only two months old. Cranks fine when the outside temp raises back up to around 45 degrees f and up. While driving today on the interstate, on the bridge, the car randomly lost all engine power. Trying to step on the gas pedal would result in the car studdering. I turned on the emergency signal and just cruised into the side lane out of traffic. Turned the car off and on and noticed the RPM idled at 1500 RPM which is insanely high. I put it in 1st gear and gave it gas, and nothing happened. The RPM meter wouldn't go up. After a few more times of cutting the engine on and off and the engine wouldn't start a few times also, it finally started and seemed to work normally. Now the car has a check engine light on.

On 08/02/2014 at approximate 6 p.m., my 2012 genesis r-spec 5.0 sedan completely stalled out as I was coming to a stop at a major intersection. There was no warning or indication of any issues up to this point. It took several attempts at starting the vehicle before it finally started and continued under its own power. This type of unexplained power loss could lead to a very serious accident. The engine warning light is currently not indicating any problems so I doubt if there are any trouble codes stored. I have owned the vehicle since new and it has always been garaged and never in a accident.
