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.
Stellantis stretched the Wagoneer name across two wildly different products, and only one deserves consideration. The gas-powered version is a spacious three-row hauler with a strong turbo six and genuinely comfortable highway manners, think of it as a Tahoe alternative that trades GM's proven reliability for slightly nicer interior materials and Stellantis's signature electrical quirks. You'll deal with infotainment freezes and the occasional dead battery, but it'll get your family where they're going. The Wagoneer S electric variant is a different animal entirely: owners report repeated 12V auxiliary battery failures that strand the vehicle mid-drive, documented unintended acceleration incidents, and dealer networks that can't fix the problems. Several are pursuing lemon law buybacks, and Stellantis paused US production until 2027. If you need three rows and can stomach the depreciation hit, the gas Wagoneer works, just budget for electrical gremlins. Skip the Wagoneer S entirely.
