• Signs of failure: A loss of power, rough idling, or unusual engine noises can indicate this problem. 
• Resolution: Engines built after October 2021 should have this issue resolved, and there have been recalls to address affected vehicles. 

Other common problems

• Carbon buildup: Older versions of the engine can develop carbon buildup on the intake valves, which may cause rough idling, misfires, or power loss. 
• Timing chain rattle: This can occur in some earlier models and is often caused by loose tensioners. 
• Ignition system: Problems with ignition coils and spark plugs have been reported. 

How to address these problems

• For oil leaks: Check for leaks and have them repaired, which may involve re-sealing the oil pan or other gaskets. 
• For intake valve issues: If your vehicle has signs of a failed intake valve, have it inspected by a professional immediately. In many cases, this requires a full engine replacement. 
• For carbon buildup: Modern 2.7L EcoBoost engines have dual-injection systems that help mitigate carbon buildup. If carbon buildup is a suspected issue, it may require a professional cleaning service.
