I had a phenomenal 2020 Camry that got totalled out by a hail storm here in Abilene Texas a few months back. Since then I’ve gotten a 2020 Colorado with 48,000 miles and the dealership’s had to replace the Fuel Pressure sensor, Fuel Pump, and Front and Rear U-Joints all within the first month of ownership. Previous owner probably couldn’t be bothered with it. I think I’m out of the hot water now that those things have been taken care of. Seems like a great truck now that all of those things are fixed. Drives great, Idles great, 4-wheel-drive works nice on steep, rocky, inclines too. What else should I bring to their attention before my 60 day warranty goes out and what major flaws should I be aware of? (And how do I get rid of this pesky cylinder deactivation?) Thanks, Scotty!
Mostly pretty good trucks. The V6 is a solid motor. And I like the auto rear locker on the Z71.
But the 8-speed transmission is by far the greatest risk (specifically the torque converter). There is an open class action suit on that unit.
Take it out on an empty road and accelerate through all the gears 3 times: hard acceleration, medium, and gentle. See if there are any rough shifts. If it is shifting smooth, you’re probably ok. But don’t tow with it and change the fluid frequently as Scotty says. I also agree with getting an OBD chip to suspend the cylinder deactivation (check the search bar above; there are previous discussions here about that.)
(FYI: the baby Duramax uses the 6-speed, which is a good transmission. But they didn’t make many of those.)

They make cats so you can deactivate that stupid system have one installed. No, I'm not a GM fan but you own it. So take care of it. Change the transmission fluid every 30,000 mi and baby it
