Service bulletin SSM 52447
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Some 2020-2024 F-150 and 2021-2024 Bronco vehicles equipped with a 2.7L or 3.0L EcoBoost engine may exhibit a ticking/tapping or rattle type noise from the top front cover area of the engine on initial start-up after a cold soak of 6 hours or more that may last for 2-5 seconds. This may be due to a stuck internal component of the variable cam timing (VCT) unit. To correct the condition, replace all 4 of the VCT units following Workshop Manual (WSM), Section 303-01. For claiming, use causal part 6C525 and applicable labor operations in Section 6 of the Service Labor Time Standards (SLTS) Manual. If labor times are not available, claim M-time.

Some 2020-2026 Aviator/Explorer/F-150/Bronco/Ranger vehicles equipped with a 2.7L or 3.0L (non-diesel) engine may need the front engine cover removed and reinstalled for various reasons.
