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.
Infiniti's three-row family hauler splits cleanly at 2022: before that year, you're buying a Pathfinder in a tuxedo with a CVT that grenades itself before 100k miles, and after it you're getting a genuinely improved interior wrapped around a wheezy turbocharged four-cylinder that takes eight full seconds to drag 4,700 pounds to highway speed. The current version looks sharp and undercuts German rivals by $15k, but the ride is stiff and loud for something wearing a luxury badge, and you're still paying a $15k premium over the mechanically identical Pathfinder for nicer leather and a different grille. One owner made it to 400k miles on a 2015, but that's the exception that proves the rule, most pre-2022 owners are nursing failed transmissions, dead alternators, and $5k timing chain bills while watching their resale value crater. Buy the new one if you want Highlander space without the Toyota tax and can live with the gutless engine, or skip the brand entirely if you're shopping used.
