GM is upgrading its warranties for used vehicles it sells in the U.S. under its GM Certified Used Vehicles program and its Saturn Certified Pre-Owned Vehicles program. The upgraded warranty coverage now gives new buyers of used cars 12-months or 12,000 mile bumper-to-bumper protection that. The coverage replaced the 3-month or 3,000 mile warranty.

GM also said that it will extend the age and mileage eligibility standards for a GM Certified used cars to include models up to six years with up to 75,000 miles.

“As we reach the 3-million sales milestone, this warranty enhancement adds a real point of differentiation for our program, enabling our dealers to offer customers a range of peace-of-mind assurances that compare favorably with any other manufacturer-certified program in the industry,” said Brian McVeigh, general manager of GM’s Fleet and Commercial Operations.

GM Certified vehicles include Buicks, Chevrolets, GMCs and Pontiacs - Saturn’s program operates separately.
