Discover what is covered by a manufacturer-backed GM warranty.
Consumers who purchase a new GM vehicle receive a GM Warranty. What is covered by a GM Warranty -- and how long it is covered -- depends on the manufacturer of the vehicle. As of 2009, GM vehicles included Chevrolet, Buick, Pontiac, GMC, HUMMER, Cadillac, Saturn and Saab. As with most vehicle warranties, the length of time an automobile is covered by a GM Warranty is measured by the vehicle's age and mileage.
The GM New Vehicle Limited Warranty covers every new GM car and light-duty truck. These GM cars include those manufactured by Chevrolet, Buick, Pontiac and GMC. According to General Motors' official Web site, this warranty offers base warranty coverage, including tires, for three years or approximately 37,000 miles, whichever comes first. This base warranty covers all items except those listed under "What is not covered" in the warranty booklet. The power train component is covered for five years/~100,000 miles. Diesel engine components are covered for five years/~100,000 miles. Sheet metal corrosion is covered for three years/~37,000 miles, and sheet metal rust-through is covered for six years/~100,000 miles. The emission control warranty is for three years/60,000 miles. Consumers receive roadside assistance for the duration of the New Vehicle Limited Warranty as well as towing and lockout services, both of which have a maximum allowance of $100.
CarBuyingTips.com warns consumers to be aware of the GM New Vehicle Limited Warranty because the company often advertises it as a five-year or 100,000-mile warranty. Consumers need to realize that only the power train is covered for five years/~60,000 miles. The full coverage on a GM vehicle expires after three years.
This GM Warranty differs for Buick and HUMMER vehicles. For these vehicles, the base warranty coverage, including tires, lasts for four years or ~50,000 miles. The power train is covered for five years/~100,000 miles. Sheet metal corrosion is covered for four years/~50,000 miles, and sheet metal rust-through is covered for six years regardless of mileage. The emission control system is protected for four years/~50,000 miles. The GM Warranty for Saturn vehicles is very similar to the GM New Vehicle Limited Warranty.
Consumers purchasing Cadillac vehicles receive a warranty with better coverage than that offered under the New Vehicle Limited Warranty. Base warranty coverage, including tires, lasts for four years or ~50,000 miles. The power train component is covered for five years/~100,000 miles. Sheet metal is protected against corrosion for four years/~50,000 miles and against rust for six years regardless of mileage. Those who purchase a Cadillac vehicle receive free regularly scheduled maintenance during the first four years or ~50,000 miles. They also receive roadside assistance while the power train is covered along with towing, fuel delivery, a jumpstart and help with a flat tire or lockout.
Customers who purchase a vehicle made by Saab receive a GM Warranty offering coverage for a longer time than the GM New Vehicle Limited Warranty. The base warranty coverage, including tires, lasts for four years or ~50,000 miles. The power train on a Saab is warranted for five years/~60,000 miles. A Saab is protected against sheet metal corrosion for four years/~50,000 miles and rust for six years regardless of mileage. The emission control system is covered for eight years/80,000 miles. The seat belts and supplemental restraint system are protected for five years or an unlimited number of miles.
GM offers several extended protection plans consumers may purchase. These plans offer coverage in addition to that offered by the standard GM Warranty. Extended protection plans cover components against failure even if the failure results from normal wear and tear. Consumers also receive alternate transportation or a rental vehicle during the repair as well as roadside assistance for the duration of the plan, which is longer than that offered under the basic GM Warranty. Customers can choose plans with deductibles ranging from $0 to $100 per repair. GM offers a tire protection plan that covers the repair or replacement of tires damaged from road hazards such as nails and potholes. The plan can be purchased for three, four or five years and allows up to $40 per tire for each repair and up to $399 per tire for replacement.
In addition, GM offers different extended protection plans for those purchasing Saturn or Saab vehicles. The supplemental Saturn Service plan can extend coverage for up to six years or ~100,000 miles. The Saab Service plan offers customers many options in terms of deductible and coverage. All GM extended protection plans are transferable to a new owner if the original owner sells the car.
