I have a 2020 Chevy Trailboss with the 5.3L and I am deleting the active/dynamic fuel management on it after it rolls over 20K on the speedometer. I’ve been hearing quite a bit on the topic as well, so I did some research and what I’ve seen goes back to 2019 at least with all 6.2L and 5.3L engines being an issue, with 6.2L being the worst. Another issue of concern, the auto start while sitting at red lights, etc. I’d expect premature wear of starters etc, involved in that as well.
