This is a truck with a split personality that depends entirely on when it rolled off the line. The 1999-2010 models with the 4.0L inline-six built a cult following by refusing to die, owners routinely push them past 200k miles with nothing but oil changes and the occasional sensor swap. The 2011-2020 generation trades some of that bulletproof simplicity for refinement, and while the 3.6L Pentastar has a known oil cooler weakness (plan for a $1,600 repair eventually), plenty of these trucks still deliver reliable service once that's addressed. Then 2021 arrived and quality control fell apart: transmissions failing at 3k miles, electrical systems going dark, the kind of catastrophic breakdowns that make you question whether anyone test-drove these before shipping them. If you're buying used and find a well-kept pre-2021 model, you're getting proven capability. If you're considering anything current-gen, you're gambling on whether Stellantis sorted out the gremlins, and right now, the house is winning.
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.
