America's longest-running nameplate still does what it's always done: move more people and cargo than almost anything else. Built on a full-size pickup frame since 1935, it's the original family hauler that never abandoned its truck roots. The sheer size means you'll pay at the pump, expect mid-teens fuel economy with the V8, and parking takes planning. Upper trims push into luxury SUV pricing where Navigator and Expedition become real alternatives. But if you need three rows, serious towing capacity, and that specific Suburban presence, nothing else quite fills the role. Just know you're buying capability over efficiency, and the size is both the point and the compromise.
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.
