When accelerating while turning a corner the engine loses power completely. In a heavy traffic situation this has caused near accidents and oncoming drivers to slam on the brakes. Vehicle begins at a dead stop. 1/2 way thru the turn there is always a complete loss of power and car stalls for several seconds until power returns. This happens every time while accelerating around a corner. Scary

On december 22nd, 2015, I was driving the car into my parking lot at my office when the car began to accelarate on its own. This is the second time in the last 6 months that the engine has accelarated without depressing the accelerator and then continued to rev higher when the car is put into park. If it was not for some quick thinking, I almost went into a wall of the garage. I immediately called the hyundai dealer and spoke to the service manager. He could hear the reving of the car. He asked if I felt safe driving it to the dealer which I did. All thoughout the ride, the car continued to accelarate on its own. When I arrived at the dealer and turned the car off, the car stopped doing this. The dealer kept the car for 5 weeks and could not duplicate or find any problems. I have asked to speak to someone at hyundai to see what the next steps are if it happens again

On december 18, 2015 at approximately 4:45pm, my husband and I were beginning our trip to an event. We were stopped at a stop light, about the 4th or 5th car in line to turn left onto a major road. There are 2 lanes for turning left and we were in the turn lane next to the lane that goes straight across the main road because we were going to have to make the first right onto the interstate after getting on the main road. We had already come to a complete stop and had been stopped for probably a minute or so. Cars were also stopped behind us. It is a steep hill, and we were facing uphill so his foot was firmly on the brakes. Then all of a sudden the engine just started roaring like it was full throttle and it took off forward and hit a nissan frontier pickup truck in front of us. It went under the truck's bumper and kept plowing forward. He tried to take it out of gear and it would not go. We watched as the hood kept crumpling more and more as we were lifting up the truck as we were going under it. The back wheels of the truck were off of the ground. I finally thought to reach over and turn the engine off. Thank the lord, it shut off before anyone got hurt.

I was driving at 35 MPH in the lane, the car on the left lane hit the rear body and tire of driver side, but the car didn't stop even after the impact. After the collision, I pressed very hard on the brake pedal to stop, but it kept moving, even increased its speed up to 60 MPH, and turned into the different direction. Also the wheel was stuck by itself and I was not able to turn anywhere with my hands. It went off the opposite side of the road without any control. 20 years old toyota camry was able to stop at the spot of collision, but hyundai genesis couldn't. The wheel and the brake were both stuck and unable to be controlled and crashed into the electric pole. The air bag was deployed, and hyundai genesis was totaled. In 2014, the brake recall service was received two times from the dealer. There must be the mechanical failure in the brake, speed control, and the wheel which caused this total loss. I was injured and taken by the ambulance later. I never had any accidents like this before with any other cars!

Car loss all forward power, speed dropped to 20 MPH accelerator had no effect. After pulling to side of road engine would not go above 2000 RPM in neutral. Engine light came on, limped to dealer. Dealer diagnosed as trouble code c15, throttle body assy. Dealer replaced throttle body, drove car for 50 miles in 4 days. Now have the same problem, engine light on and no power. This is a very dangerous problem. Will have car towed back to dealer. Loosing power with no warning while driving on the interstates or pulling out into traffic is dangerous and safety problem!!!!!!!
