Interesting timing, my 2020 just started doin this too, fun.My 2018 went in for cam phasers today.The noise at cold start began about 2 weeks ago. Last friday, it was knocking at any speed unless it was under load. I was about 150 miles from home when it got really bad. Wasn't sure if I was going to make it back or not. My mechanic didn't seem too worried. But we'll see in a day or so when he opens her up. Ran fine.... but sounded real unhappy.
***EDIT - I should add that records showed they were last replaced in 2020, before I bought the truck.
Odd cause im pretty sure this truck was build when they released the new parts and it had the latest revisions.
Change oil every 2500 as well, oh well im still under warranty at least.
