Quick answer

Some 2021-2023 F-150 vehicles equipped with minor feature codes HKRAC (8 inch instrument panel cluster (IPC) screen) and HKCAA (SYNC without navigation) may exhibit a condition where the compass direction indication is stuck or not updating correctly in the IPC. To confirm a vehicle is built with minor feature codes HKRAC and HKCAA, review the build information by double-clicking the vehicle identification number in the upper left-hand corner in the Professional Technician System (PTS). This may be due to a software concern in the instrument panel cluster (IPC). Engineering is currently working on a software update to address this concern. Inform the customer they can continue to drive the vehicle. For 2021 F-150 vehicles exhibiting this concern, perform Technical Service Bulletin 21-2388 and confirm if the concern is still present. Monitor for OASIS for updates.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
