Kia EV6 Front Radar Unit (99110CV000)
Updated June 20, 2026
The 99110CV000 is a genuine OEM front radar sensor assembly designed for the 2022–2024 Kia EV6. This millimeter-wave radar unit is the primary sensor for the vehicle's adaptive cruise control (ACC), forward collision warning (FCW), and autonomous emergency braking (AEB) systems. Mounted behind the front grille, it continuously measures the distance and relative speed of vehicles ahead, enabling the EV6's advanced driver assistance features to operate accurately.

Function and Role in the ADAS System
This radar unit emits radio waves and analyzes the reflected signals to detect objects in the vehicle's path. It provides real-time data to the ADAS control module, which then adjusts cruise control speed, issues collision warnings, or applies brakes automatically. The sensor has a specific field of view and range calibrated for highway and city driving. It works in conjunction with the front camera (if equipped) for sensor fusion, but the radar remains the primary sensor for distance measurement in low-visibility conditions.
Vehicle Fitment and Compatibility
The 99110CV000 is exclusively designed for the Kia EV6 produced from 2022 through 2024. It is a direct-fit replacement for the original unit and is manufactured by Hyundai Mobis, the OEM supplier for Hyundai and Kia. The part is physically identical to the factory-installed radar and includes the mounting bracket and connector. It is not compatible with other Kia models or earlier EV6 years without modification. Always verify your vehicle's VIN and existing part number before purchasing.
Common Failure Symptoms and Diagnosis
When this radar sensor fails or becomes misaligned, drivers may notice the adaptive cruise control system becoming unavailable, a persistent 'Forward Safety' or 'Cruise Control' warning light on the dashboard, or false collision alerts. In some cases, the system may disable entirely and display a 'Radar Blocked' message even when the sensor is clean. Physical damage from minor front-end impacts is a common cause, as the grille-mounted unit is vulnerable. Diagnostic trouble codes (DTCs) such as C1202 or C1203 often point to radar signal issues. A professional scan tool can confirm sensor communication faults.
Installation and Calibration Notes
Replacing the radar unit is mechanically straightforward—it typically involves removing the front grille or lower bumper cover, unbolting the old sensor, and installing the new one. However, after installation, the sensor must be calibrated using a specialized ADAS calibration tool. This process ensures the radar's aim is correct relative to the vehicle's forward axis. Calibration often requires placing targets at precise distances in front of the vehicle and following a manufacturer-specific procedure. Some listings note that the sensor may need programming or reprogramming to match the vehicle's VIN. Without proper calibration, the ADAS features may not function correctly or may produce false readings.
