The GMT900 debuted at the 2006 North American International Auto Show, as the next generation full-size pickups and SUVs, and replacements for the GMT800 vehicles. The first GMT900 vehicle is the next-generation Chevrolet Tahoe.

GMT900 has been called a "Hail Mary pass" for General Motors — the company needs the revenue from these large trucks to continue operating profitably, and the failure of the series could result in insolvency. The company's resources were focused exclusively on GMT900 development through 2005, delaying other programs like the GM Zeta platform. With the 2005 spike in gasoline prices, some analysts have questioned the wisdom of "betting the company" on a line of large trucks, but initial sales have been brisk with no need to resort to rebates.

The GMT900 series features standard vehicle stability control. Original plans called for American Axle's "I-Ride" independent suspension module in the rear, but this appears to have been cancelled.

Short wheelbase (Yukon/Tahoe) GMT900 production began at GM's Arlington Assembly plant in Arlington, Texas on December 1, 2005, six weeks ahead of schedule. Production of the SWB versions began at Janesville Assembly in Janesville, Wisconsin in early 2006. Production of long wheelbase trucks (Suburban/Yukon XL) begins in Janesville and at Silao Assembly in Silao, Guanajuato, in March. The Avalanche will be produced only in Silao, while the Escalade will be based in Arlington.

The SUVs began to show up at dealers in January 2006. Sales so far have exceeded expectations, with GM asking suppliers to ramp up parts production in advance of the launch of the remaining models.

The related Silverado and Sierra pickups started production in late 2006. The HUMMER H2 was meant to move to the new platform in the next few years, but has since been cancelled.
