I had a squeaking in my right passenger pillar/dash area on my 2020 AT4 from the start upon buying it. Had it to the dealer twice, they said they could never replicate it... all you had to do was drive it and it squeaked every time all the time. I tried figuring it out to no avail for over 2 years. When the stereo was playing (most of the time) it pretty much drowned it out, but it was still annoying as hell. I traded that truck off on Jan 4th of 23 for a 2023 AT4X. No rattles or squeaks thankfully on mine.
Hope you get it figured out OP.
