To bolster its reliability image, General Motors stretched the standard warranty to cover its entire 2007 car and light-duty truck lineup in the United States and Canada up to 100,000 miles or five years. The new warranty is a fully transferable five-year, 100,000-mile power-train limited warranty with no deductible. GM also has expanded its roadside assistance and courtesy transportation programs to match the power-train warranty term.
The new warranty covers more than 900 components related to the engine, transmission, transfer case (if applicable) and final-drive assemblies on all 2007 model-year Chevrolet, Pontiac, Buick, GMC, Hummer, Saturn, Saab and Cadillac cars and light-duty trucks sold in the United States and Canada. It applies retroactively to 2007 GM cars and trucks already sold. For non-power-train components, GM's Bumper-to-Bumper New Vehicle Limited Warranty remains in effect: four years or 50,000 miles for Buicks, Cadillacs, Hummers and Saabs, and three years or 36,000 miles for Chevrolets, GMCs, Pontiacs and Saturns.
