Same here!!!!The 5.3L engines with the active fuel management in that vintage have some serious oil pump issues. I had a 2006 Envoy Denali that went to the junk yard with just under 100K on the clock after the engine ate its bearings following a single no oil pressure cold start.
The 2006 5.3L is not forward or backward compatible with any other model year 5.3L so finding a replacement engine is quite difficult, if not impossible (unless you want the roll the dice on a junk yard motor). Having the engine pulled out and rebuilt would have cost more than $9000 at the time (2016) so I cut my losses and sent the Envoy Denali to the junk yard.
I will take the bus before owning another GM vehicle.
My last was an Avalanche. I loved that truck, It was very comfortable, drove smooth. But it ate wheel bearings for lunch.......
