A 15-year-old platform that still sells because it's the only three-row SUV offering a 392 Hemi and 7,000-lb towing under $60k. The current generation (2011+) has genuinely matured, owners report the 5.7 Hemi runs strong and the ZF8 transmission holds up, a stark contrast to the catastrophic engine failures that plagued pre-2011 models. The tradeoff: it guzzles premium fuel, the interior feels a decade behind, and those HVAC blend door seals turn to goo on 2011-2019 models, gluing your vents shut. Buy it if you need V8 power and towing in a family package and accept you're choosing driving fun over efficiency. Skip it if you want modern tech, fuel economy, or the peace of mind a Telluride or Highlander delivers.
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.
