option for standard-length Envoys and was the standard engine for the Envoy XL; all versions received a 22-gallon fuel tank. 2004 The model year was largely carryover for the Envoy SUV. For the interior, adjustable pedals became an option, alongside XM Satellite Radio and an optional DVD-based navigation system. Derived from the Envoy XL, the Envoy XUV was a retractable-roof vehicle, combining the design capability of a SUV with a pickup truck. 2005 Following the discontinuation of the Oldsmobile Bravada, GMC expanded its Denali model range to the Envoy for 2005, including both versions of the model line. Along with its own grille design and chromed alloy wheels, the interior received standard leather trim, heated power seats, rain-sensing windshield wipers, and upgraded wood trim. For all versions of the Envoy, GMC introduced revised seats; optional side airbags were replaced by full-length side curtain airbags (covering all three rows of seats in the Envoy XL). The DVD navigation system option was updated, adopting a touchscreen interface. The 5.3L V8 was upgraded with a variable-displacement Displacement on Demand system, using four of eight cylinders in low-workload driving. 2006 For 2006, Stabilitrak stability control was made a standard feature alongside cruise control, OnStar, and a tire pressure monitoring system. The Envoy Denali received updated 18-inch alloy wheels. Following low sales of the vehicle, the Envoy XUV was dropped from the model line for 2006. 2007 Following the discontinuation of the Envoy XL, all versions of the model line were now offered with five-passenger seating. 2008 For 2008, side-curtain airbags (introduced as an option in 2005) were made standard. 2009 For 2009, few functional changes were made, with Bluetooth wireless technology for wireless phones added as a new option. Following the closure of Moraine Assembly, GMC ended sales of the model line after the 2009 model year, with its role in the GMC line largely succeeded by the GMC Terrain CUV wagon. It was the final model year. Recall In 2012, General Motors had 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 20 U.S. states, Washington, D.C., and Canada, where salt and other chemicals are used to clear roads
