U3000 on Kia by model: symptoms, diagnosis and fix
The Advanced Driver Assistance Systems on the K5 — including Lane Keep Assist, Forward Collision Avoidance, and Blind Spot Monitoring — intermittently throw calibration faults and disable themselves.
Common Symptoms
- Lane Keep Assist warning light and system disabled
- Forward Collision warning malfunction message
- Blind Spot Monitor not functioning
- Multiple ADAS warning lights on dashboard
How to Fix
For intermittent faults in normal conditions: clean the windshield interior and exterior thoroughly around the camera area. Ensure the camera lens cover behind the rearview mirror is clean and unobstructed. After windshield replacement, ALWAYS have the ADAS camera recalibrated at a Kia dealer — this requires specialized targets and equipment.
Owner tips & cautions
- WarningIf you get your windshield replaced, INSIST on ADAS recalibration. The camera must be recalibrated to the new windshield or your safety systems will not function correctly. Budget $300-$500 for this.

Frequently asked questions
What does U3000 mean on a Kia?
U3000 stands for "Control Module." U3000 is a generic network code indicating a control module has detected an internal fault within itself or a related controller, or a problem in the module/CAN wiring system. It is often accompanied by a sub-fault letter or number that narrows down whether the issue is internal electronics, calibration, or a communication/voltage problem. In practice it means a module is reporting that it (or a module it monitors) is not functioning correctly, which can put the system into a protective/safe mode. On Kia it is documented across 1 model: K5.
