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.
This three-row crossover splits into two completely different vehicles by generation. The 2011-2019 Theta II models are mechanical time bombs, engines grenade between 50k-90k miles with oil burning and rod knock, leaving families stranded for months while dealers work through warranty backlogs. The 2024 redesign threw out that cursed powertrain entirely, but introduced two new problems: panoramic sunroofs that explode while driving (glass raining into the cabin, corporate denying coverage), and a 2024 dual-clutch transmission already failing at low mileage. The 2026 hybrid with conventional automatic looks promising, owners report 470-mile range and Range Rover looks at $50k, but it's too new to trust long-term. If you're buying used, the Theta II era is a hard pass. If you're buying new, the hybrid might be worth the gamble, but skip the sunroof and prepare to fight corporate if anything breaks. Honda Passport and Mazda CX-90 offer less drama.
