Automatic Emergency Braking problems of the 2022 Hyundai Kona

On four separate occasions now, I have been driving on the highway at roughly 60 mph, no cars in front of or beside me, and nothing else obstructing the roadway, when completely out of nowhere the emergency braking activates for 3-5 seconds. Thankfully there was only a car behind me on one occasion, and they were far enough behind to not collide after my sudden braking.

I was driving up an incline when I overheated, causing smoke to come out of the transmission case. The vehicle suddenly stopped in the middle of the road, which could have caused an accident or fire. Regarding the transmission, I opened the hood to let the vehicle cool down for an hour.

Two times on a highway, the car engaged the automatic emergency brakes when the driver was driving straight forward. We were not turning, breaking, or accelerating and there were no cars close to our car.

This is my 2nd report on the same issue. There is another report from me on the first and I will be discussing this with my Hyundai dealer today. On a 250 mile road trip, on the expressway, two separate times, the car suddenly braked hard and the emergency warning flashed on the speedometer. Each time it was about 3-5 seconds. On the second incident, my passenger thinks she noticed it happening in conjunction with a car appearing on my side. She said the side mirror warning lit up at the same time the car started braking. It could just be a coincidence though. Thankfully, neither time did the brakes fully stop the car, but damn, it is very scary when it happens on the expressway and I am very nervous to drive with the feature on.

Incident #1: auto emergency breaking system sensed false situation and auto braked nearly causing high speed accident. Caused while exiting I-80 west bound off ramp with two lanes ramp that exits. I was in the inside lane and there was another vehicle in the outside lane. Assuming the system thought I was going to turn into the outer car and braked suddenly. Incident #2: lane keeping system, constantly fights me for no known reason. While in las vegas on flamingo road on oct. 10, 2022 the system suddenly jerked the car to the left and nearly into a head-on crash. My family is very lucky to be okay. Car has problems when road markings are not consistent or when using reflectors (vs painted lines) or when there are exits. It's safer to leave the system off in my experience.

On 9/20/2022 I was driving on the expressway at approximately 60 mph when my car suddenly applied brakes and slowed considerably without reason and started flashing the emergency braking notification with alert noises. The notifications stopped after about 6 seconds and the car did not come to a complete stop, as I probably would not be here today, but it rattled me and now I have lost confidence in my car and feel this can cause a serious accident. The car has 1,322 miles and I have noticed one other incident at speed under 10 mph approaching traffic light. . I called my dealer to let them know. They made a note in my profile because they didn’t think they would be able to do anything. I searched google and found others have discussed the exact same issue with the same model. This should be addressed! I will be turning this feature off.

Emergency braking system stopped the car suddenly. There weren't any cars in front of me or next to me. Thankfully I was driving slow through a road in our parking lot and there were no cars behind me. It has only happened once so far. Obviously it startled me and made me wonder how safe the car is to drive. I haven't said anything to the dealer, but plan to when I go in for yearly maintenance in a week. There were no warning lights or symptoms prior to this happening.

I was driving on the freeway at about speed limit. I was at a safe distance (3 car lengths away) from the car in front of me. The emergency brake activated. It did not stop the car, but I felt a pause in the drive. The message on my dashboard stated "emergency brake activated". A few minutes later, the emergency brake activated again. Again, it did not stop the car, but I felt another pause in the drive. The message "emergency brake activated" also came on the dashboard. I had a passenger in the car.

During collision, airbags did not deploy. In attempt to avoid collision, automatic breaks failed and did not stop the vehicle, cruise control continued to attempt to drive the vehicle despite collision warning and did not stop- coupled with my manual breaking, the car did not stop. Car is currently at a tow lot waiting for insurance. My safety was put at risk due to airbags not deploying during serious collision, the breaks malfunctioned. At this time, the car is in the beginning stages of insurance. My car did not display any prior failure features.

I was driving on the freeway the car in front of me was at least 4 car lengths away. My car flashed emergency breaks and locked it’s breaks coming to a stop on the fast lane of the freeway. Nearly avoided an accident. This has happened twice- both with no reason and no issue in front of me to cause the car to think it needed to suddenly use emergency brakes.
