I have a 2023 Silverado with the 2.7L and I have the same issue and dealer says GM engineers are aware of the problem and working on a solution. I have it documented, but it is annoying to even drive the truck, so I have a good looking $50,000 garage trophy with 587 miles on it. I have owned a chevy since 1987 but if they dont fix this, it may be my last.
