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.
This three-row luxury SUV promises Escalade-level comfort at a lower entry price, and the cabin genuinely delivers, plush materials, spacious seating, intuitive controls. But the 2022-2024 models carry a troubling pattern: transmission seizures before 40k miles, electrical failures that strand owners, and service waits stretching into months. One mechanic's warning about a third transmission failure in two weeks tells you what dealership techs see daily. Depreciation is brutal, reflecting market awareness of these issues. The 2026 refresh brings a new inline-6 engine that may address some problems, but lacks real-world proof. If you're leasing short-term, the comfort might justify the risk. If you're buying, the Expedition and Tahoe offer similar space without the reliability gamble.
