Took truck to Ford dealer. They ran diagnostics and found that Body Control Module (BCM) has water damage evidence and was starting to fail. Water source was a leak in windshield that went behind dash (where BCM is located). All handled all warranty. Looks like something that occurred in assembly process. QC process obviously didn’t catch it.
