2024 KIA EV9 Forward Collision Avoidance Adaptive Cruise Control Problems

The dashboard and control panel of my vehicle have repeatedly blacked out since shortly after purchase. These blackouts cause the entire instrument cluster and control systems, including critical safety features, to become non-functional or obstructed intermittently while driving. This creates a dangerous situation where I lose access to important information such as speed, warning indicators, and climate controls, severely compromising my ability to operate the vehicle safely. The issue has occurred multiple times, including once while driving on a highway, which put me and other drivers at significant risk. The problem has been reported to authorized dealerships, where the vehicle was inspected and software updates were attempted, but the issue persists. Despite multiple repair attempts, the blackouts continue to happen unpredictably. There have been no specific warning lamps or messages prior to the blackouts; the system simply fails without notice. The malfunction affects the vehicle’s safety system by obstructing the...

Certain ADAS features have disengaged at least six times in the last year. While traveling at greater than 55 mph vehicle disengages cruise control and reports numerous warning indicators on dashboard including ADAS forward features such as collision warning and automatic braking indicators. I also noted lane management/steering also seemed to disengage when this has occurred during highway curve management. It is difficult to evaluate the full range of loss as the dashboard warnings are numerous and change over the next few minutes. It is also unsafe to secure good photographic evidence when traveling alone, though with assistance some imagery was recently captured. The sudden loss of speed and directional control assistance in multi-lane urban traffic was alarming but managed OK by alert driving. The manufacturer's dealer reported they could do nothing after one of the first occurrences. They said there were not 'codes' registered and not reports on file....

Vehicles accelerates aggressively to no limit (95+) when adaptive cruise control is set and there is no leading vehicle within following range.

Over 10 times I've had errors come up on dashboard about sensor systems that are not working. Cat has been taken in 5 times for this with no resolution. I can provide numerous dashboard pictures going back since I purchased the vehicle

My EV9 lunged forward very abruptly when I was parking. I had to slam on the brakes before my vehicle crashed into the building in front of me. My vehicle also lost the signal (blank screen while driving ) the same day my car lunged forward. I could not tell how fast or slow I was going. I pulled over and restarted the vehicle or and my screen came back on. I began driving for maybe 4 minutes and the screen went completely black except for the “lost signal” alert in red. My vehicle has also lost the ability to use adaptive cruise control while driving my vehicle. I pulled over and when I restarted the vehicle i was able to use it again.

When the vehicle is in adaptive cruise mode and tracking a lane with Lane Keeping Assistance, if the lines on the road widen beyond a certain point (perhaps 3-5ft wider than a normal lane), the vehicle will suddenly stop maintaining the lane with no audio warning or significant visual indicator. As the driver should always be paying attention, it is the lack of an audio warning that is the major concern. On a straight road, the vehicle will slowly begin to drift out of the lane. However, when this happens on a curve, the vehicle will suddenly stop steering around the corner, and throw the vehicle out of the lane in a dangerous way. This happens all the time when the lane widens, which I often experience on newer freeways with wider lanes. If a fix can't be provided for the system shutting down, it at least needs an audio...

The screen that shows speed, miles remaining, etc. went black on a long trip. All of the automated cruise control, lane keeping, etc. are also housed in that screen. The blinkers would not work, I had no idea how fast I was going at any time which is unsafe. I could not see how much range is left on the vehicle which I imagine could lead the car just dying while driving or going into the turtle mode with too low of a charge. Also, the adaptive cruise control was not working properly and at one point when a car in front of me moved over out of my lane, the car accelerated hard and brought me up to about what was probably about 90-100mph, not even close to where it was set earlier. 2 hour drive without screen or these safety features and the screen still is not back....

I turned on the car and the main gauge cluster screen was black - I was not able to see speed, use turn signals, use advance driver systems, etc. Completely unsafe to drive.

Infotainment went out, to include speedometer while driving did not come back on till the following day.

While using adaptive cruise control on the highway, my car almost rear ended the car in front of me when it surged ahead around a slight curve in the road. I was travelling approximately 5mph below the set cruise speed due to the traffic ahead. It appears that my vehicle lost radar sight of the car in front and tried to get back up to the set speed. This has happened on multiple occasions now.

When in Highway Drive Assist mode, where the system controls the speed and lane keep and lane change, the system can disengage without any visual or audio warning. This causes dangerous scenarios where the driver believes the car is in control but it is not.
