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.
Toyota built a reputation on the 2008-2022 Sequoia's unkillable 5.7L V8, owners routinely cruise past 300k miles on oil changes alone, and one just hit 500k before needing spark plugs. The 2023 redesign looks sharp and the 437-hp hybrid hauls hard, but the cargo area is a mess: the battery placement means the third row won't fold flat, leaving you with a stepped floor where the Tahoe gives you actual usable space. The twin-turbo V6 is unproven long-term, fuel economy still hovers around 16 mpg, and you're paying $75k+ for the privilege. If you need three-row towing muscle and don't mind dated tech, hunt down a clean second-gen and enjoy bulletproof engineering. If you want the new one, load it with your actual gear first, that weird tiered trunk might be a dealbreaker, and at this price the American competition suddenly looks reasonable.
