I was driving on the highway with no one in front of me. The car suddenly slammed on the brakes and flashed "emergency breaking system" on my dash. My car went from about 75 mpg down to 50. The car behind me almost rear-ended me. He then proceeded to pass me and brake check me because he thought I had deliberately brake checked him. This incident caused the man behind me to get road rage and react dangerously to me. I hit the gas and it finally stopped breaking and let me gain speed up again. It was terrifying. This is not the first time this has happened but it was the first time in the highway. It has happened several times on side roads for no reason either. I have an appointment with Hyundai to figure out what they can do because I don't feel safe driving this car.

At high speeds above 40 MPH vehicle automatically brakes with no vehicle or objects in front while vehicle is in operation. Very concerning when driving on interstate.

Feb 2025 Crash Injury

My car automatically braked in the middle of an intersection and caused my vehicle to be rear-ended. This was the third time automatic braking engaged when it should not have been. In the most recent incident on [XXX] I was injured and had to have medical attention. I googled automatic braking and there were many reports of automatic braking being deployed when it should not have been.

Sudden hard breaking for no reason. It's happened 3 times when in cruise control. If a car had been close behind it would have caused a wreck. I've had the vehicle just over a month

While driving in light traffic, speed at 45 mph, my Tucson alerted me with a beep, steering wheel vibrated and a red alert on the dash was present for about 3 seconds then the speed automatically slows down to 15 mph all on its own while my foot is still on the accelerator. This has occurred at a minimum 6 times. I purchased this vehicle brand new and driving it off the lot it had 22 miles on it. I've taken it to a Hyundai dealership, and they can't figure out what it wrong with it. I feel very unsafe and unhappy now of this major safety concern. This has high probability of getting rear ended. I see that this has been occurring with various years of Hyundai and am wondering why there has not been a recall on this issue. I owned a Hyundai prior to this 2024 (Tucson 2011) and it was wonderful. This is highly concerning for me, and I am not confidant driving this vehicle and will more than likely trade it in for another vehicle. Can someone please research this issue with the automatic emergency brake system. This can autonomously go off whether you are in traffic, highway, street or completely zero vehicles or pedestrians around.

Two incidents while driving on the highway. 1. Emergency braking activated on its own. No cars around me. It was a rural area. The red emergency braking activated light showed up and my car braked but resumed driving. This is a new car with less than 4k miles on it. 2. The hands free assist and cruise control were activated. My care swerved to the right abruptly. My hands were on the wheel and I was able to correct this but this is very concerning as my daughter drives this car on mountain roads when she is going to college. I have read online reports when others driving the same make, model and year vehicle.
