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.
Toyota built a reputation on the 2008-2022 Sequoia's unkillable 5.7L V8, owners routinely cruise past 300k miles on oil changes alone, and one just hit 500k before needing spark plugs. The 2023 redesign looks sharp and the 437-hp hybrid hauls hard, but the cargo area is a mess: the battery placement means the third row won't fold flat, leaving you with a stepped floor where the Tahoe gives you actual usable space. The twin-turbo V6 is unproven long-term, fuel economy still hovers around 16 mpg, and you're paying $75k+ for the privilege. If you need three-row towing muscle and don't mind dated tech, hunt down a clean second-gen and enjoy bulletproof engineering. If you want the new one, load it with your actual gear first, that weird tiered trunk might be a dealbreaker, and at this price the American competition suddenly looks reasonable.
