There was an SSM on this very issue. Unfortunately Ford has removed it from the TRC. I'll keep looking to see if I can find it. No worries though as the SSM stated this was a normal startup strategy of the 3.5L Ecoboost.

** Side Note - One thing of note is that I had just filled up the tank with premium 92 (my first time filling the tank).
I can assume the dealer filled it with 87 regular when they gave it to me.
Could it be a spark knock or something to that affect because of the difference in fuel type?
I just assumed my engine would run better/cleaner if I stick with 92

All ecoboosts do this or have this noise but maybe not as loud as you are describing.
Its a blow off valve sound - maybe a defective one in yours?

Any of you seen my videos of my 2017 F150 clunk on engine startup?
and here is the link to the forums where others are talking about it.

2017 f150 Clunk can be heard 40 feet away on startup version 2 (I looped the last few seconds of video so you can hear the clunk being repeated. If you think about it, how loud must the clunk be to be heard 50 feet away??

2017 f150 Driveshaft clunking on engine start 3 level grade resting on parking brake

Note how the driveshaft rotates slowly in both directions after the engine has been started.

This was the first time I saw the drive shaft move while the engine was being started.

Add me to the club. Have been hearing this “clunk” since the beginning. Very intermittent. It was only doing it when I would start it. Just today it did it when t I shifted to park from reverse. I was actually able to record it but it’s not as clear as the other videos here. Already have a case with Ford over a lot of other issues. This truck has been a nightmare ever since I needed a new fuel injector at 4,500 miles. It’s a 2018 and currently has about 6,500 miles.
