At times it seems the 6.2 gremlins appear to be random events. I've heard of various year models having bad batches of lifters, cams, etc. I had a 2018 in the midst of those "bad batches" that I ran to 100k, and is now at 200k with no issues...just change the oil and run the crap out of it. So who knows. But if you get bit by it and its not covered under warranty its gonna be expensive.I've got a 2020 GMC AT4 1500 6.2L with 55K miles on it. Its been an incredibly reliable truck and have been really happy with it. Knock on wood only issues I've had with it have been needing to get the idler pulley replaced and some electrical gremlin that makes the navigation SD card unreadable at times (still have that latter issue).
I've read a bunch of posts about lifter issues but have not experienced them myself and praying I don't since my power train warranty is up at the end of the month :-(
