2024 Hyundai Kona

This mainly concerns the forward collision detection sensor, if that’s even what it’s actually called. My vehicle is available for testing and inspection. I was driving on an interstate, with my adaptive cruise control set to 75 mph. I was in the left of 3 lanes when got to a curve that went to the right. As I came to the beginning of the curve, all of a sudden my dash is warning me of a forward collision and the car started braking hard on its own. There is a metal guardrail that separates the 2 sides of the interstate and cars are also coming from the other direction. There wasn’t anyone behind me, thank goodness. If there had been, I can’t say for sure what would have happened, but it would not have been good. It took a hot minute for me to figure out what it was doing so I could stop it and get back up to speed. It scared me when it happened. When I go the same way without my cruise control on, it doesn’t happen. That’s how I know it has something to do with how it’s all connected. This has happened twice at 2 different places since I got the car in May of 2024. I don’t use my cruise control hardly at all now because I’m scared it’s going to suddenly brake again. I wasn’t sure what could be done about it. I put the info on the Hyundai owner surveys but nothing ever happened. I found the NHTSA completely by accident. I want someone to inspect it and try to recreate it, but it’s an awfully dangerous thing to try. Nobody has yet. It’s not like it’s a noise or a rattle. The only thing that I would consider a warning was the crash detection warning on the dash screen that flashes red. That started right about the time that the brakes were activated.

My wife was driving and braked on a hill, not in park. The emergency brake auto-engaged while she was in park, then the emergency brake disengaged automatically. The care starts rolling down the hill, the regular brakes fail and do not work after pumping them multiple times. The emergency brake won't engage either. She tries reversing and that won't work. She shifted the car into drive, car keeps rolling, then she was able to engage the regular brakes and she turned into my driveaway to avoid hitting a wall or other cars. The brake system warning light turned on during this time, indicating some failure in the brake system.

While driving my 2024 Hyundai Kona on the freeway on May 22, 2026, at approximately 9:30 AM, traveling around 75 mph, my vehicle suddenly displayed a forward collision warning on the dashboard even though there was no vehicle, object, or road hazard in front of me that would justify emergency braking. Immediately after the warning appeared, the vehicle’s automatic emergency braking / forward collision avoidance system activated on its own, causing the car to brake abruptly and rapidly decelerate in active freeway traffic. This created an extremely dangerous situation because vehicles behind me were traveling at freeway speeds and could have rear-ended me, potentially causing a serious multi-vehicle collision resulting in serious injury or death. I had no warning prior to this event, no dashboard warning lights, service messages, or other symptoms indicating a problem with the system. The suspected failed component is the forward collision avoidance / automatic emergency braking system, and the vehicle is available for inspection upon request. The issue has not yet been reproduced or confirmed by a dealership or independent repair facility, and the vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or others. My best assessment is that the system falsely detected a collision risk and activated emergency braking without cause, creating a severe highway safety hazard.

On Monday [XXX] I was driving home from work going 45 mph when my forward collision warning came on and the car stopped. However, there was no one in front of me. This was extremely dangerous and if there was a car behind me I could have been hit. I am extremely scared to drive this car. I had it towed to Lynne’s Hyundai in Bloomfield NJ. They said their computer could not find an issue so had nothing to fix and asked me to pick up the car. However, after what I experienced I refused and called corporate Hyundai. They told me my safety was their number one priority and they would resolve this for me. However, after they spoke to the dealership they said they could not duplicate the problem so nothing could be done. I gave numerous solutions that would make me happy but none were taken. I now have a car I am literally scared to death to drive and had another malfunction with the front sensor yesterday where it told me the car in front of me was pulling away but it was stopped. The vehicle is available for inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

while traveling from MN to KY on the interstate on two separate occasions the vehicle suddenly applied the brakes at Highway speeds around of 80mph. There was nothing Infront of me on either occasion. Then the next day it did it again at highway speed. Then I was driving on a mountain road in the smokies and it gave me a message that the front camera was blocked, and it was turning off the safety braking etc, I stopped when I could and took pictures there was nothing blocking the camera. I had a similar problem in March of this year which is documented by Hyundai Customer service as the Dealership told me that they could do nothing to help me.
