2015 GT 5.0 knocking at start-up?
I have a 2015 GT that makes a loud knocking-ticking-rattling noise at startup anybody else? What was the cause?

for how long? if it's just brief, it may be that the timing chain tensioner (hydraulic, uses engine oil pressure) has to pump up.

What gas grade are you using? What grade did you have in it prior to the knocking?

It does it at startup until the it idles down, maybe 15-25 seconds.

I'd get into a dealer! If it is low in the engine & dull knocking you could be losing a a main or rod bearing! I had one go out in a Ford V8 in the first 300 miles! Ford service laughed & smiled until I started it up & then said OH ****! New engine! Good luck!

Dealer says the Resonator coming apart inside, there is a TSB on it. Ordering the part will let you know if that fixes it.
