Car has began doing this often now. At 115k miles. Start the car, put it in drive, car won't move. Put it in reverse. Same issue. Have to turn the car off and on and repeat until it moves. Occasionally I'll stop at a stop sign and go to move after stopping and again, it won't move. Engine just revs. Have to repeat above until it moves. Replaced camshaft sensor and knock sensor. Didn't fix it. Now the car dies while in park and stalls between 15-2000 rpm. There are several forums with the same issues and no one has a solid answer. And no recall. Insane. Taking it to Hyundai and considering a lawsuit with my evidence and all the other forums and complaints.
