2.7L EcoBoost - Cold Start Ticking/Tapping Or Rattle Type Noise
21 October 2022


2019-2022 Edge
Engine: 2.7L EcoBoost
2019-2022 Nautilus
Engine: 2.7L EcoBoost


Issue: Some 2019-2022 Edge/Nautilus vehicles equipped with a 2.7L 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 stuck internal components of the variable cam timing (VCT) unit. To correct the condition, follow the Service Procedure to replace the VCT units.


Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:


• 2019-2022 Edge/Nautilus

• 2.7L EcoBoost engine

• Customer symptom of ticking/tapping or rattle noise from the front cover area after a cold start


NOTE: Dealers should only order parts for customer vehicles that require repairs. Because of part constraints, dealers may experience situational short-term backorders on some parts. Customers should continue to drive vehicles while parts are on order.

I was wondering if this noise can be identified separately from other noises under the hood?  Such as the high pressure fuel pump and with the hood closed and an engine cover on top also. The only unusual noise I hear once in a while is a metallic sound when starting, more like a noise that would come from starter engagement? Basically just wondering if this is something that would definitely be noticeable and if there's any other factors involved such as mileage and age of vehicle.

I have a 22 ST with the 2.7.  I don't necessarily hear this tapping or rattle noise on start up, but I do think that the engine is a bit noisy when you are outside the vehicle with it running and standing in front of it.  It does seem to make a constant fast clicking noise all the time on mine.  I attributed this to fuel injection or something else "normal" as it runs smoothly to me.  It doesn't make any different noise the first 5 seconds than it does all the time.  I also wonder what the problem is if it only does it, as reported, for 2 to 5 seconds after it starts, is there really a problem?  Is it harming the engine?
