I ran your VIN; your truck currently has Field Service Action (FSA) 21B10 open, which is a reprogram of the PCM to prevent the issue from occurring. However, the FSA is on hold due to issues with the new software. Once the software issue is resolved, the dealer can perform the FSA. That will then open up FSA 21N03, which is the bulletin to have the phasers replaced with the updated parts to resolve the cold start rattle.
If you bought the truck new, I’d recommend contacting Ford customer care and see if they’ll cover the repair. If not, contact your dealer and ask them to notify you when the new software for 21B10 is available so you can move forward with the repair under the extended coverage.
