If you want a Tahoe that'll outlive your mortgage, hunt down a 2000-2006 GMT800, the last generation before GM added Active Fuel Management and turned oil consumption into a lifestyle. Those trucks routinely hit 250k miles with just a transmission rebuild somewhere past 150k. Everything from 2007 forward carries the AFM lifter time bomb: one collapsed lifter means a $5,000 engine teardown, and the 6L80/8L90 transmissions fail even when you do everything right. The 2021 redesign rides better and looks sharper, but dealership techs report transmission replacements at 1,400 miles, and GM's killing CarPlay in 2026, locking you into their buggy infotainment forever. Buy a GMT800 if you want peace of mind, or budget for an AFM delete the day you sign. Skip this if you want a full-size SUV that doesn't require a maintenance prayer circle.
One nameplate, two universes. The 1984-2001 XJ with its 4.0L inline-six is the unkillable legend owners drive past 600,000 miles on oil changes alone, simple, tough, easy to fix in a driveway. Then came 2014's Fiat-platform KL, where transfer cases grenade before 100k, electrical gremlins multiply like tribbles, and replacing an evaporator means pulling the doors off. Mechanics who wrench on Stellantis products all day drive Hondas home. The all-new 2026 hybrid promises redemption with premium materials and modern tech, but it's engineered by the same outfit that just spent a decade using the Cherokee name as a punchline. Hunt a clean XJ if you want the legend. Skip the 2014-2023 models unless you enjoy surprise $4,000 repair bills. Wait on the 2026 until someone else beta-tests it.
