KIA AEB system stands for the autonomous or emergency braking system that uses radars, sensors, and cameras mounted on the front and rear side of the car to monitor the surroundings. It triggers the vibration on the steering wheel and gives the warning message. However, it automatically applies the brakes when detecting anything approaching your vehicle.
KIA check AEB system alert shows on the car screen because of a disabled AEB system, the issue with headlights, faulty brake components, damaged sensors and cameras, incorrect message on a computer system, speed limitations, sensors and cameras blockage, and electronic interference.
You should contact the authorized KIA dealers for inspection when the warning indicator illuminates the screen. Moreover, you can drive the car with this warning message, but you have to be careful because the malfunctioned system does not automatically apply brakes after detecting the presence of vehicles or obstacles. You should remain active to respond quickly to the visual and audio sounds.

Disabled AEB system
Check if you have disabled the AEB feature. Sometimes, people intentionally deactivate the safety features to drive actively on the road.
In addition, you can also unintentionally deactivate the safety mode and then forget to activate it. Moreover, it can be automatically disabled because of the faults in its components and several working limitations.
You can see the warning message when faulty components cause the deactivation of the automatic emergency braking system. You can find the defective components through diagnostic trouble codes.
Connect the scanner devices to the OBD-II port of your vehicle and read the code.
Issue with headlights
Autonomous or automatic emergency braking systems also work in low-light and dark conditions. Sensors and cameras detect the presence of vehicles and obstacles in their surrounding because of the headlights.
Headlamps provide illumination so cameras can sense the presence of objects. Sometimes, the headlights become faulty, and cameras cannot detect nearby objects.
The headlights become defective because of the corroded wiring, insufficient power supply, blown-out fuse, bad relays, and burned bulbs.
Moreover, headlights can also become faulty because of water ingress. In addition, the brightness of the headlight bulb becomes low because of the bad relays.
It automatically shuts off when cameras stop functioning in dark and low-light conditions. You have to replace the burned-out bulb of the headlight with a new one.
You can increase the longevity of headlights by keeping them clean and reducing the chances of rusting. Replace the damaged headlight fuse and relay with a new one.
Faulty brake components
This system works with the safety feature to apply brakes in emergencies. It automatically engages the brakes when you do not respond to the vibratory steering wheel and visual warning message.
The AEB alert message comes on the screen when it stops functioning because of the faulty brake components. It cannot engage the brakes when its components become faulty and have low brake fluid.
Brakes cannot function because of the low brake fluid levels. It cannot work because of the contaminated and overheated brake fluid. It cannot efficiently engage the brakes because of damaged and corroded rotors and discs.
It is better to check the brake fluid levels and add the fluid for efficient brake application. Moreover, you have to replace the contaminated brake fluid with a new one.
Damaged sensors and cameras
Autonomous emergency braking systems use sensors and cameras to detect pedestrians, objects, and other cars in their surroundings. These sensors and cameras are mounted on the front grille and windshield.
Moreover, the location of these devices can also vary depending on the model of the KIA vehicle. AEB system can malfunction due to damaged sensors and cameras because of not receiving the specific output.
It triggers the warning alert so you can check the damaged sensors and cameras. These can get damaged because of side impacts, road accidents, hitting of road debris, and water ingress.
You have to replace the damaged sensors and cameras with new ones to restore the functioning of safety features.
Incorrect message on a computer system
AEB system uses the computerized system to show message alerts and take input from the sensors and cameras. Its computer sometimes shows the incorrect message on the display screen because of bugs and software glitches.
In addition, the issue also comes because of the faulty ABE system module. Moreover, you can also face problems because of the software glitches that trigger the false notification.
You can remove the software bugs by resetting it. Reset your vehicle’s infotainment screen by pressing the power and volume buttons simultaneously for 10 seconds.
Driver assist safety features, including cruise control, only function in your Kia car when driving at a certain speed. Cameras and radars are also designed to work at recommended speed limitations.
These cannot recognize the vehicle when it is speeding by you. The AEB system malfunctions and shows the warning indicator when you do not follow the recommended speed guidelines.
The issue comes when you drive at a high speed of over 80 mph. You should keep the speed between 50 to 70 mph for safe driving.
I was driving my Kia, and suddenly the rain started in the middle of the journey. I saw the AEB system alert, which showed that the automatic emergency brakes were malfunctioning.
I was worried because it was working before the rain started. I ignored it and drove carefully on a wet road because of the chances of slipping.
However, the warning alert disappeared when the weather became fine and dry. I realized this safety feature cannot function in wet or adverse weather conditions because of decreased visibility.
Cameras cannot spot obstacles and vehicles during dark conditions and rainy or foggy weather. It is better to turn on the headlights to enhance the camera visibility.
Sensors and camera blockages
You can also see this AEB message on your KIA car’s screen because of the blocked sensors or cameras that work with this feature to engage the brake and reduce the risk of collision.
Installation of windshield tint and stickers causes blockage of cameras, and these cannot detect the objects. In addition, the issue also comes when you put some stickers on the windscreen for decoration purposes.
Environmental attractants, including small insects and bugs, can also stick to the front mirror glass and obstruct the view. My friend said he faced the issue when he changed the direction of the license plate in his car.
He did not know about radar sensors on the rear side. He saw the notification and checked the cameras, but those were fine.
He contacted the dealership, and the mechanic told him the license plate needed replacement because it obstructed the radar sensors functioning. Moreover, you have to reprogram these devices in your vehicle after windshield and front grille replacement.
Electronic system interference
Sensors cannot function because of the interference from the electronic devices in your cars. The issue comes when you turn on the multiple electronic devices in your vehicle.
Sensors also use the electric mode to send the signals to the ECU. However, some of these function on the radio signals technology. You can also face problems because of interferences from the radio devices.
A faulty sensor can temporarily disable the automatic emergency braking, and you can see a warning alert on the display screen because it malfunctions.
It shows that ECU cannot receive the signals from the cameras or sensors because of the faulty counterparts. Turn off the electric and radio signal accessories to reduce interruption chances.
