The 2003-2008 Isuzu Ascender is a full-size SUV that was produced by Isuzu Motors Limited and sold in the North American market. It was essentially a rebadged Chevrolet Trailblazer, sharing the same platform, powertrain options, and many design elements. Despite its close ties to the Chevrolet model, the Ascender aimed to offer a slightly more refined and luxurious driving experience, targeting buyers seeking a dependable and spacious SUV with a touch of sophistication.

The Ascender was available in various trim levels, including the base S, the mid-range LS, and the top-of-the-line LT. All models came standard with a 4.2-liter inline-six engine producing 275 horsepower and 285 lb-ft of torque. A five-speed automatic transmission was the sole transmission option, delivering power to either rear wheels or all four wheels depending on the selected configuration. While not known for its sporty performance, the Ascender offered a comfortable ride, decent handling for a large SUV, and ample interior space for up to seven passengers. Its interior featured comfortable seating, reasonably high-quality materials, and a relatively user-friendly layout. The Ascender was generally well-regarded for its reliability and durability, making it a popular choice among families and individuals seeking a spacious and dependable SUV. However, it faced stiff competition from established players like the Ford Explorer and Toyota 4Runner, ultimately contributing to its discontinuation in 2008, marking the end of Isuzu's attempt to gain a foothold in the American SUV market.
