Complaint Summary

FORWARD COLLISION AVOIDANCE: WARNINGS

Owner Narrative

I am reporting a concern regarding the Forward Collision Warning and Automatic Emergency Braking systems on my 2024 Kia Sportage SX Prestige. I have been attempting to understand the operating behavior of the vehicle’s FCA system using cardboard boxes as targets. I conducted observations at very low speeds (approximately 5 mph) as well as at approximately 30 mph. During these observations, the vehicle did not provide a forward collision warning or automatic braking at distances at which I expected the system to recognize a potential collision. I have not intentionally caused a collision or placed a person or another vehicle in danger. I am uncertain whether this behavior represents normal FCA operating limitations, the use of an inappropriate target, or a malfunction or calibration issue. I am therefore reporting the concern rather than asserting that a defect has been established. I am also uncertain what diagnostic or functional validation procedure Kia provides for this system. I have been able to find information regarding radar alignment, camera calibration, and diagnostic fault checking, but I have not been able to determine whether Kia provides dealers with a standardized functional test that verifies that FCW/AEB actually recognizes an appropriate vehicle target and intervenes at the expected point. The concern has not yet been reproduced or confirmed by a dealer or independent service center. The vehicle has not yet been subjected to a standardized ADAS functional test using a recognized vehicle target. No warning lamps or diagnostic messages have appeared that I am aware of. The potentially affected components are Forward Collision Warning and Automatic Emergency Braking within the vehicle’s Advanced Driver Assistance System. The vehicle is available for inspection upon request.
