The Ascender is the only one of GM's GMT360-based mid-size SUVs that was not actually GM-branded. The Ascender LWB was dropped after the 2006 model year. Reviews warned of a thin dealer network for warranty repairs, and the Kelley Blue Book projected a relatively low resale value similar to the TrailBlazer. However, Isuzu offers a seven-year/75,000-mile powertrain warranty, and substantial factory incentives.

Five-passenger Ascender

The Ascender ended production on June 6, 2008, as part of Isuzu's withdrawal from the United States market.[1] The Ascender (along with the related GMC Envoy) were both replaced by the 2010 GMC Terrain, based on the GM Theta platform. 7-passenger versions of both SUVs were indirectly replaced by the GMC Acadia in 2007, based on the GM Lambda platform.



In 2012, General Motors and Isuzu recalled more than 258,000 SUVs in the U.S. and Canada to fix short-circuits in power window and door-lock switches that could cause fires. The recall covered Chevrolet TrailBlazer, GMC Envoy, Buick Rainier, Isuzu Ascender and Saab 9-7X SUVs from the 2006 and 2007 model years. The SUVs were sold or registered in the United States also including Hawaii and Alaska and Canada as well.

General Motors announced the recall of 316,357 vehicles in late 2014, primarily in North America, to fix malfunctioning headlights. According to the company, a problem in the headlamp driver module could have led to temporary or permanent malfunctioning of the low-beam headlamps and daytime running lamps. This increased the possibility of an accident. However, the high-beam headlamps, marker lamps, turn signals and fog lamps are not affected by the issue. The vehicles that were covered under the recall are the 2006–2009 Buick LaCrosse sedans; 2006–2007 Chevrolet Trailblazer, GMC Envoy and Buick Rainier SUVs; and 2006–2008 Saab 9-7X and Isuzu Ascender SUVs.[2]
