Multiple K5 owners and NHTSA complaints document unexpected, uninitiated hard braking events triggered by the Forward Collision Avoidance Assist system in the absence of any actual obstacle. The issue represents a safety concern as following vehicles may be unable to react in time, increasing rear-end collision risk.

How to Fix
Ask a Kia dealer to check the VIN for any available forward-safety (FCA) software updates. Owners should have the forward radar sensor (part of the front bumper radar module) and windshield camera inspected for alignment. In persistent cases, FCA can be temporarily disabled via the Driver Assistance menu, though this is not recommended as a permanent fix.
