Significant concerns from real users
⚠ Elevated risk
AFM (Active Fuel Management) lifter collapse on 2007-2020 models causes engine damage requiring expensive teardown. 6L80 and 8L90 transmissions fail due to torque converter and valve body design flaws even with proper maintenance. 2021+ models show early transmission failures at very low mileage. GMT800 (2000-2006) avoids AFM entirely and is the most reliable generation.
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.
The generation that matters
This product isn't one story — here's how each era is regarded.
2007–2014 (GMT900)
2007–2014
Strong
Praised for reliability and longevity (200k+ miles common). Users specifically recommend this generation to avoid AFM/transmission issues found in later models. The 6.0L in 2500 Suburbans particularly well-regarded.
2015–2020 (GMT K2XX)
2015–2020
Compromised
Multiple users warn to avoid 2015+ due to widespread AFM and transmission (8-speed) problems appearing frequently. Represents a step backward in reliability from the previous generation despite newer tech.
2021–present (GMT T1XX)
2021–present
Solid
Major redesign with independent rear suspension improved ride/handling/refinement significantly. Experts praise on-road manners and earned 10Best recognition, but too new for long-term reliability data. 2025 refresh adds larger screens and updated styling.
