2022 Hyundai Kona driver assistance problems

Filed Oct 12, 2026 · Driver assistance · NH

The vehicle is a 2022 Hyundai Kona N Line, VIN [XXX]. The driver-assistance/safety systems have intermittently malfunctioned. The reported problems include false forward-collision warnings, unintended automatic emergency braking when there is no apparent obstacle or collision threat, false blind-spot/side warnings, and unwanted steering intervention from the lane-assist system. The exact failed component is UNKNOWN. Possible involved systems include the Forward Collision-Avoidance Assist system, Lane Keeping/Lane Following Assist, Blind-Spot Collision Warning/Collision-Avoidance Assist, related cameras/radar sensors, control modules, wiring, or software. The vehicle remains available for inspection upon request. These malfunctions create a serious crash risk because the vehicle may unexpectedly brake or steer while traveling at highway speed. Three different drivers in my household have independently experienced abnormal behavior from these systems. My greatest concern is that sudden braking or steering intervention could cause the vehicle to be struck from behind, leave its lane, enter another lane, or collide with another vehicle or fixed object. The vehicle was taken to AutoFair Hyundai for inspection and diagnosis. The dealership stated that it could not reproduce the condition during its evaluation and did not find a stored diagnostic trouble code. The dealership therefore did not identify a specific cause or perform a repair directed at the reported forward-collision, blind-spot, braking, or steering malfunction. A rocker cover assembly was replaced under warranty for a separate issue. The dealership has stated that it is checking whether the affected driver-assistance systems can be permanently disabled. Hyundai Motor America has also been notified through a national customer-care case. Hyundai is aware that the complaint remains unresolved. There are not always warning lamps or stored fault codes associated with the events. The symptoms are INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

Today, my Kona tried to kill me. I was traveling on a freeway in a construction zone. Road conditions were clear: no fog, precipitation, potholes or obstructions. Traffic slowed down to 30 mph as the rightmost lane becomes an exit only lane (and people exchanged between the middle and right lane). Traffic continued to flow freely around 50 mph in the left lane. I was in the middle lane, and after passing the off ramp my lane was clear for at least an eighth of a mile ahead (all visible traffic in front of me had taken the exit). I began to accelerate back up to freeway speeds when the "Automatic Emergency Braking" engaged for no reason. There was a curved driving path on the display (which read "Automatic Emergency Braking"), and it seemed like the car was trying to force me into the left lane (underneath a semi truck). I could feel the same motored pull that the Kona has while using the "lane keeping assistance" feature. But unlike the lane assist which takes 20 pounds to manually override, this took approximately 80 pounds of force to fight. Even fighting the turn, I was multiple feet into the left lane. The only reason I was not crushed by the wheels of the semi trailer is because the driver was hugging the left side of their lane. I was nearly rear-ended and the 4 cars behind me nearly had a pile-up because of this as well. My best guess is that it detected the cement barrier along the side of the curved road and incorrectly determined that I was on a collision path with it. Since it was a construction zone, the cement barrier was approximately 3 feet outside of the lane. In reality, this feature is not production ready and needs to be fixed/removed from the fleet.

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.

As I was backing out of my driveway, I noticed my camera started flashing a green screen and a message appeared intermittently with the flashing green screen saying ‘no camera signal try again later. This lasted the entire time I was backing up including once I shifted into drive then it disappeared. I feel that this is a safety risk to others who may be walking or driving by me if I am unable to use the camera. Clearly I don’t rely completely on the back up camera as I still tend to look at my surroundings as I back up. I am not even certain if someone was behind me if the warning would even work when the camera is acting up. I have not reported the problem to the dealer yet but I will first thing in the morning. The vehicle has not been inspected yet. The warning messages are described in the first paragraph. Today is first time this has happened. I have a video of this but was not able to attach it.

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.

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.

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

Cruise control on the 2022 Kona is not viable. In the standard cruising gears the cruise control is unresponsive for a long duration resulting in reductions of speed of up to 11 MPH at highway speeds, in traffic. The response of the cruise control to following a car can take up to 1 minute to actually try and recover speed.

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.
