Three rows, serious towing capacity, and enough space to swallow a hockey team's gear, the Yukon XL handles the big-family hauling job when it's running. But the 6.2L V8 in recent models has a rod bearing problem: engines seizing under 40k miles, sometimes at highway speed, with replacement waits stretching into months while you're handed the keys to an Equinox. The 3.0L diesel avoids most of this drama, delivers 27 mpg highway, and pulls strong. If you're buying new, skip the V8 and load up on warranty. If you're shopping used, the 2000-2014 trucks earned their reputation for going 200k-plus; the current generation is a different story. Buy the diesel or buy something else.
If you're shopping three-row SUVs and the Sorento catches your eye, know this: generation matters more than brand loyalty here. The 2011-2020 models earned their reputation the hard way, owners report needing two or three complete engine replacements before 110k miles, with Kia dragging its feet on warranty coverage until recalls forced action. The 2021-and-newer models fixed the engine drama but swapped it for DCT transmission failures in the turbocharged EX and higher trims, typically around 70k miles. The bright spot? The current Sorento Hybrid runs a bulletproof conventional six-speed automatic and delivers 32 mpg without the powertrain anxiety. It's genuinely competitive if you can live with a tighter third row than the Highlander offers and don't need to tow a boat. Skip the older generations entirely, and if you're buying new, either go Hybrid or stick with the base engine and transmission, the turbo DCT combo is a $6,000 repair waiting to happen.
