From 2002 through 2009 model years.
After taking a few years off, Chevrolet's TrailBlazer is back in Thailand. We got a sneak peek of the 2013 TrailBlazer last year at the Dubai International Motor Show, and it will debut next week at the Bangkok International Motor Show. It will go on sale first in Thailand this June; global markets will follow DETROIT — General Motors' Chevrolet division could expand its SUV lineup in the U.S. next year with the addition of a midsize pickup truck-based model derived from the Thai-built Trailblazer. The Trailblazer shares its global body-on-frame architecture with the midsize Chevrolet Colorado pickup truck. The seven-passenger Trailblazer debuted at the 2012 Bangkok Auto Show and went on sale last year in a number of overseas markets, including Thailand, Brazil and the Philippines. GM has said it plans to sell the vehicle in 50 global markets, including the Middle East and Australia. The first-generation 2002–2005 model years TrailBlazer is based on a truck platform called GMT360, with all models having four-wheel drive as an option with both automatic engagement and the more traditional 4 High and 4 Low gearings, except the SS model which features an All wheel drive system. The 6-cylinder versions of the TrailBlazer get up to 20 miles per US gallon (12 L/100 km; 24 mpg-imp) highway, according to refreshed United States Environmental Protection Agency estimates. The TrailBlazer won the North American Truck of the Year award in 2002. The 4.2 L I6 Atlas LL8 appeared on the Ward's 10 Best Engines list from 2002–2005 with innovative features such as DOHC, Variable Valve Timing (VVT) on the exhaust camshaft, and GM's patented Lost-foam casting process Just the Facts: Chevrolet could expand its SUV lineup in the U.S. next year with the addition of a midsize model based on the Thai-built Trailblazer.

Production of the EXT model was handled by the Oklahoma City Assembly plant in Oklahoma City, Oklahoma.

The Trailblazer as a vehicle was discontinued as of the 2009 model year.
