I've had this happen a few times on my 23 Palisade. I am not using the Nav system at the time that it occurs, just driving down a divided road in town. It seems to be triggered in the same location on the road where there is a break in the median, to turn left, but I stay straight. I am in the left lane when it happens. In the previous instances, I was able to pull into a parking lot, turn the car off and it cleared the warning. Today (5 Dec 22), it came on and I couldn't clear it by turning the car off. I drove on I-95 for about 40 miles with the annoying warning beeping each time that I changed lanes. When I got to my interim destination, I started the Nav system to get to my next destination and that cleared the warning. On the way home, I stopped by the Hyundai dealer and spoke with a tech. He was baffled and couldn't figure it out. He suggested updating the Nav software, which I will begin here shortly. I told him that my thoughts are that there must be a sensor that isn't calibrated, which is telling the Nav system that the car is going the wrong way. The tech agreed that it's a possibility. He said if updating the software doesn't work, to bring it in and they would check the sensors. We shall see.
