3.5 Ecoboost Rattle

[railroad]

Someone outside my truck, on start up, commented on the engine rattling and then getting quite.

I looked it up and found it to be a common issue, with timing chain stretch and VCT actuators being bad.

I have extended warranty on my 2013 F150, 43K miles.
I have a recall on a speed sensor in the trans and trying to get in for evaluation.

Any first hand experience on this?
My research shows it on going from 2011 up to 2019.

My guess would be cam phasers, a known issue with the 3.5. 5.0 can have this issue to with miles. Have it looked at while under warranty. They will probably have to have it and have it sit over night and do a cold start good luck.
