Jeep Cherokee collision warning problems

Filed Oct 9, 2026 · Driver assistance · FL

I am reporting a safety concern involving the Forward Collision Warning (FCW) system on my 2021 Jeep Cherokee Altitude FWD with a 2.4L engine. Every time I start the vehicle, the dashboard displays the warning message "FCW Unavailable – Service Required." The warning remains displayed while I am driving, indicating that the Forward Collision Warning system is not functioning properly. This is a safety concern because the vehicle is equipped with Full-Speed Forward Collision Warning Plus, which is designed to help warn the driver of potential frontal collisions. With this system unavailable, I cannot rely on its collision warning and automatic emergency braking functions. The issue occurs consistently during vehicle operation. The exact cause of the malfunction is currently unknown. I am requesting that the federal safety agency document and review this safety concern and determine whether further investigation is warranted.
