- Summary
- Some 2018-2019 Expedition/Navigator vehicles built on or before 8-Apr-2019 equipped with a 3.5L 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 worn variable cam timing (VCT) unit. To correct the condition, follow the Service Procedure steps to replace the VCT units and update the powertrain control module (PCM) calibration with revised VCT parameters.
Owners of these vehicles have filed 417 complaints in the transmission category.
