we have had no issues with this vehicle at all. then one day notice a ticking in the area of the valve covers. Sounded to be more on drivers side. Thought maybe just the oil was low which has never happened before. Oil level was fine. I always change oil on regular intervals and there were no check engine lights and engine continued to run fine with no loss of power or ticking changing. It was our only vehicle so we had to continue to drive that day. Wife was driving and said vehicle shuddered and started sounding funny and check engine light came on she was able to drive back home. Now ticking is worse with a clucking rattling sound now coming from oil pan. After some internet searching it very much sounds like issues many others are having with the 6.2l GM engine.

The V8 engine on our family's 2019 GMC Yukon Denali XL check engine light came on and began ticking while taking our daughter to college in Montana. The dealer informs us the engine has probable lifter failure and will need to be disassembled to diagnose additional issues. The estimated repair costs are from $3,000 to $10,000+, may require a new engine, and we will be without the vehicle for almost two months. We are incurring additional costs such as lodging, airfare to fly home, costs for an additional car, and storage for a travel trailer that must remain behind. The warranty on our vehcle expired last year. The vehicle has been consistantly serviced at our local dealer. Research and discussions with other GM customers inform us this is a known issue for our year and that a recall was issued for vehicles for 2021 to 2025.
