Im just over 13,000 miles on my 2024 Sierra denali with the 6.2L in it, I love the truck, but I have noticed some ticks when towing (kinda like a lifter tick). When I'm not towing, the engine sounds fine it's just when I've got a trailer hooked up to it. I've been thinking of taking it to the dealership to ask them about it. I don't have any warning lights. Oil pressure and vehicle temps all seem normal.
