Solid choice with some caveats

GM's upscale twin to the Silverado wins on looks, even Ford loyalists admit it's the best-looking truck you can buy, but the engine choice matters more than the badge. The 5.3L V8 is the workhorse: proven across 200k-mile police fleets, boring in the best way. The 3.0L diesel hits 28 mpg when it works, but some batches grenaded early, and the 6.2L left 2020-2022 owners stranded with catastrophic failures. The infotainment skips and mutes itself on 2022+ trucks, a known bug GM has ignored for years. Pricing has crept into luxury territory, lawyers and soccer moms, not the working crowd. Buy a pre-2020 model for proven reliability, or spec a new one with the 5.3L and a strong warranty. Skip the 6.2L on anything 2020-2022, and roll the dice on the diesel only if fuel economy justifies the risk. It'll tow your world and turn heads, as long as you pick the right engine and forgive the screen's morning mood.

The context that matters

What you're actually buying — and what the data leans toward.

Clear generational divide: pre-2020 models regarded as reliable workhorses, 2020-2025 models show emerging infotainment and engine issues. 5.3L remains most reliable across all eras.
