Other than the Tahoe Limited and Z71, the vehicle was redesigned and launched in January 2000 for the 2000 model year on the new GMT800 platform, still shared with the full-sized pickups and SUVs. Two new engines replaced the 5.7L (350 cu in) Chevrolet small-block V8, and while both were smaller, both produced more horsepower but less torque. In Mexico, the GMT800 Chevrolet Tahoe is called the Chevrolet Sonora. A 2-door GMT800 Tahoe prototype was made but never entered production. Suburban and Tahoe models sold in Mexico still offered the 5.7L small-block Chevrolet V8 (RPO code R31) as an option in early models, whereas it was replaced by the new 5.3L Vortec V8 engine (or the 4.8L Vortec V8 in base Tahoe models) in all other markets.
Both vehicles received significant updates with only the grille, headlights and body-side moldings distinguishing one from the other. Both vehicles now featured softer lines as part of a more aerodynamic design. The interior was also updated with new seats, dashboard, and door panels.

The GMC Yukon Denali was redesigned for the 2001 model year, and the Cadillac Escalade was redesigned in 2002 (there was no Escalade for the 2001 model year).

A redesigned instrument cluster featured a new Driver Information Center, which can monitor and report on up to 34 different vehicle system functions such as Service StabiliTrak, Ice Possible, and Door Ajar. The interior was refreshed, including a new eight-button steering wheel that allows the driver to safely access new infotainment features as well as a redesigned center console.
There were also new improvements to the powertrain and electrical system for 2003. These included a new Electronic Throttle Control (ETC) system to improve throttle feel and new oxygen sensors to improve durability and reduce emissions during engine warm-up. Models sold in California received a more robust catalytic converter to meet Ultra Low Emissions Vehicle (ULEV) standards. A new battery-rundown protection system automatically turns off the headlamps, parking lamps, and interior lighting if left on for more than 10 minutes with the key removed from the ignition.

2006
2006 marked the final year of the Tahoe and Yukon on the GMT800 platform, and because of this, only minor changes were made. These changes included StabiliTrak becoming standard on all models, combining the OnStar and XM Satellite Radio antennas into one single unit, removal of the Chevrolet badging on the liftgate, removal of rubber trim from the liftglass, relocating the catalytic converter closer to the engine to improve emissions performance, and a new manual parking brake adjuster.

GMT800 (2000-2006)
В 2000 році представлено друге покоління Chevrolet Tahoe зробленого на платформі GMT 800 (база - 2946 мм). Автомобіль комплектувалися бензиновими двигунами 4,8 л Vortec потужністю 275 к.с. та 5,3 Vortec 285 к.с.
На автомобілі встановлена запатентована General Motors система Autotrac 4х4, яка являє собою керовану комп'ютером роздавальну коробку. Autotrac 4х4 дозволить простим натисканням кнопки вибирати одне з п'яти режимів трансмісії - A4WD, 4 HI, 4LO, 2HI, а також режим Neutral.
Режим 2Hi використовується в нормальних дорожніх умовах. Цей режим забезпечує економію пального, відключаючи передній міст.
Режим AUTO 4WD - автоматично підключається повний привід - підходить для їзди по дорогах зі змішаним покриттям. При прослизанні задніх коліс система в лічені секунди в автоматичному режимі підключає повний привід і відключає його, коли того не вимагають дорожні умови.
Режим 4Hi - постійний повний привід - використовується в умовах снігових заметів, ожеледиці та інших складних ситуаціях. Цей режим аналогічний режиму із заблокованим міжосьовим диференціалом.
Режим 4Lo використовується у важких дорожніх умовах - при русі по глибокому снігу, бруду, на крутих схилах і піску. Перехід в режим 4Lo вимагає зупинки автомобіля і лише потім перекладу трансмісії в цей режим.
Режим Neutral дозволяє власникам Tahoe в разі необхідності буксирувати автомобіль без ризику пошкодження трансмісії. Це один з небагатьох автомобілів з автоматичною коробкою передач, на якому пропонується дана опція.
В 2004 році відбулось незначне оновлення моделі в результаті чого обидва двигуни додали по десять к.с.
