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.
Quick acceleration, strong range, and the Supercharger network still make this a capable electric crossover, and the 2026 Juniper refresh genuinely fixes the harsh ride and cabin noise that plagued earlier versions. But the ownership experience is the catch: 2023 models leaked water through the trunk seals badly enough for Consumer Reports to flag it, delivery quality is a coin toss (paint damage, misaligned panels, even a reported roof detachment), and service is email-only with centers that can go quiet for weeks. If you can tolerate the support gamble, the fundamentals work, but the Ioniq 5, EV6, and Mach-E deliver similar capability with a company that answers the phone.
