I have 1983 miles on mine, so far the only issue was a little creaking in the passenger side of the dash when hitting a decent sized bump in the road -- Houston roads will put any car to the test (my wife's BMW had a similar issue when it was new, accept hers was along the headliner)! Anyhow, the dealer adjusted the area under the speaker, and I haven't had any issues since.
My Yukon Denali was manufactured and delivered in Febuary 2021.
Update to this post -- had lifter failure at 5,070 miles while headed out on vacation.
