The Yukon used to be the SUV you bought once and drove forever, GMT800s from 1999-2006 still cruise past 250k miles on original drivetrains, but the current 6.2L V8 has a bearing flaw that causes engines to seize without warning, sometimes at highway speed, often under 30k miles. GM recalled 2019-2024 models but 2025s are failing identically; one owner's engine died at 20k after the dealer promised the issue was resolved. If you need a new Yukon, the 3.0L Duramax diesel is the only powertrain worth trusting, though it's had scattered early turbo failures. Otherwise, find a GMT800 with records and accept 12 mpg, it's the last generation that actually delivers on the reputation.
Lincoln's flagship three-row tries to out-luxury the Escalade with a twin-turbo V6, quilted leather everywhere, and a 48-inch screen that actually makes sense. The Black Label trims look stunning, and owners who bought recent models rave about the presence and tech. But there's a gap between the showroom promise and the road reality: Consumer Reports tested the 2025 and found the ride quality and handling don't justify six-figure pricing, and some Black Label buyers report cracking lamination on white interior panels, unacceptable at that tier. The 3.5L EcoBoost (2018+) dodges the cam phaser nightmares that plagued older 5.4L V8 models, but you'll still visit gas stations constantly at 15-17 mpg. Buy it if you want maximum space and maximum screen in a Lincoln wrapper, but know the Escalade drives better and the Expedition costs $30k less.
