– General Motors has expanded its warranty coverage up to 100,000 miles or five years across its entire 2007 car and light-duty truck lineup in the United States and Canada. GM’s new 100,000-mile warranty coverage is a fully transferable five-year, 100,000-mile powertrain limited warranty with no deductible. GM also has decided to expand its roadside assistance and courtesy transportation programs to match the powertrain warranty term.The warranty 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. GM will extend the existing roadside assistance plan to 100,000 miles or five years, and will provide courtesy transportation for a covered warranty repair. The new warranty will apply retroactively to 2007 GM cars and trucks already sold.For non-powertrain components, GM’s bumper-to-bumper new-vehicle limited warranty remains in effect; four years or 50,000 miles for Buick, Cadillac, Hummer, and Saab, and three years or 36,000 miles for Chevrolet, GMC, Pontiac, and Saturn.Visit www.gm.com/warranty for more details about the program.
