Upon starting my car the engine was revving.I thought it was doing that because it was extremely cold out. I let it warm up a little. I put the car in drive it begin to accelerate by itself going up to 40 miles while in a parking garage. I managed to finally stop the car by flooring the brake petal & emergency brake. I turned the car off and restarted it and it started revving again! I called the Hyundai dealership to report what had happened.

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.

My 2012 Hyundai Genesis 6 cylinder sedan has stalled since I bought it (leased) new two years ago. Each time I go to the dealer (oil changes, etc.) and ask them about it they say they have not heard of this problem and since they cannot recreate it when they drive the car they tell me there is nothing they can do. Just a short time ago my family and I were almost in a very serious accident - there almost certainly would have been a fatality if I had not left enough room when turning left in front of oncoming traffic on a state highway. As with all but one of about 8 stalls the engine cuts out as the car slows to at or just below 5 mph. This time oncoming traffic cleared me by inches as I muscled the turn without power steering and the car coasted to safety. This has become unbearable. I will be going to the dealership as soon as possible. This car stickered at $45K - I have had more expensive and comparably priced cars, Audi, BMW, Cadillac, etc., but have never had a problem like this! it did stall once at 45 mph but all other stalls have been at the point of almost stopping or, in tonight's case, decelerating somewhat rapidly as in a left turn from 55 mph. Please help with this issue. I cannot find anything specific on-line although apparently elantra's have the same issue(?). have found a few postings from other Genesis owners, but I cannot follow them - I am not a mechanic - they talk about turning "ESC" on and/or off; which I know is electronic stabilization control, but, I am not comfortable trying to strong arm a solution - especially for such an expensive car. Again, please, please help with this problem. I will go to dealership again, but I know what they are going to say...what else can/should I do?

The common denominator for what I experienced has been that the car is moving slowly, 5-20 mph (7th or 8th gear), and you floor the accelerator while changing the lane (to merge quickly). All that happens for 1-2 seconds is that the car coasts at the speed you were going (absolutely no power is applied to the wheels), and you see the revs going up and the transmission shifting to a lower and lower gear (but not sending any of that power to the wheels), until it gets to the 2nd or 3rd gear and then your head snaps back as it accelerates very quickly (but 2 seconds too late). So instead of the expected takeoff you get 2 seconds of coasting while the car in the lane that you got into is getting uncomfortably close and has to brake to prevent an accident. This is extremely dangerous and unexpected.

Genesis 6-cyl

In 2011 I leased a 2012 Hyundai Genesis. On January 25.2013 when my car suddenly stopped. I called aaa, they came out and did a diagnostic check on my battery and told me it was fine, that something in the computer, most likely the alternator was draining the battery. On June 9th 2013 while driving my vehicle in traffic at approximately 50 mph my vehicle completely shut down. I came to a stop and it started up again. I proceeded to drive approximately 3 more miles at 45 mph, my vehicle again completely shut down, no steering no brakes. After coming to a complete stop I proceeded to the nearest service station and again contacted aaa. They came out, did a check on my battery and told me the same thing, something in the system is draining the battery. On July 8th 2013 it happened again. Aaa came out jump started my car and advised me to take it to the dealership. I drove my car to planet Hyundai on.w. sahara ave. In las vegas, Nevada and told them of my problem, I left the vehicle with them. The next day they told me that they replaced the battery. I made them aware of the stalling in traffic issue weeks before, I spoke with a certified tech who told me it was absolutely not a battery issue and that person called Hyundai service department and told them the same thing. I contacted Hyundai customer service and spoke with jacqueline who after conferring with planet Hyundai told me they were unable to duplicate the problem and they could do nothing. To work with the dealership. The head of the service dept. Told me that the Genesis has a sophisticated computer and these things could happen, they tested the car and could find nothing and would provide no further explanation.. I told Hyundai customer service that this is a safety issue, . Hyundai provided me with a case file # 5871296, I requested they send it to me.
