Warranty Repairs -- Component Exchanges

In the interest of customer satisfaction, GM may offer exchange service on some vehicle components. This service is intended to reduce the amount of time your vehicle is not available for use due to repairs. Components used in exchange are service replacement parts which may be new, remanufactured, reconditioned, or repaired, depending on the component involved.

All exchange components used meet GM standards and are warranted the same as new components. Examples of the types of components that might be serviced in this fashion include: engine and transmission assemblies, instrument cluster assemblies, radios, compact disc players, tape players, batteries, and powertrain control modules.

Warranty Repairs -- Recycled Materials

Environmental Protection Agency (EPA) guidelines and GM support the capture, purification, and reuse of automotive air conditioning refrigerant gases and engine coolant. As a result, any repairs GM may make to your vehicle may involve the installation of purified reclaimed refrigerant and coolant.

Tire Service

Any authorized GMC or tire dealer for your brand of tires can assist you with tire service. If, after contacting one of these dealers, you need further assistance or you have questions, contact GMC Customer Assistance Center. The toll-free telephone numbers are listed under Owner Assistance .

6.6L DURAMAX® Diesel Engine Components

For trucks equipped with a 6.6L DURAMAX® Diesel Engine, the complete engine assembly, including turbocharger components, is covered for defects in material or workmanship for 3 years or 36,000 miles, whichever comes first. No deductible applies during this coverage period. The engine parts listed next continue to be covered, subject to a $100.00 deductible, for 5 years or 100,000 miles, whichever comes first.

Important: Some of these components may also be covered by the Emission Warranty with no deductible. See the "Emission Warranty Parts List" under Emission Control Systems Warranty for details.

Aftermarket Engine Performance Enhancement Products and Modifications

Some aftermarket engine performance products and modifications promise a way to increase the horsepower and torque levels of your vehicle’s powertrain. You should be aware that these products may have detrimental effects on the performance and life of the engine, exhaust emission system, transmission, and drivetrain. The Duramax Diesel® Engine, Allison Automatic Transmission®, and drivetrain have been designed and built to offer industry leading durability and performance in the most demanding applications. Engine power enhancement products may enable the engine to operate at horsepower and torque levels that could damage, create failure, or reduce the life of the engine, engine emission system, transmission, and drivetrain. Damage, failure, or reduced life of the engine, transmission, emission system, drivetrain or other vehicle components caused by aftermarket engine performance enhancement products or modifications may not be covered under your vehicle warranty.

After-Manufacture "Rustproofing"

Your vehicle was designed and built to resist corrosion. Application of additional rust-inhibiting materials is neither necessary nor required under the Sheet Metal Coverage. GM makes no recommendations concerning the usefulness or value of such products.

Application of after-manufacture rustproofing products may create an environment which reduces the corrosion resistance built into your vehicle. Repairs to correct damage caused by such applications are not covered under your New Vehicle Limited Warranty.

Paint, Trim, and Appearance Items

Defects in paint, trim, upholstery, or other appearance items are normally corrected during new vehicle preparation. If you find any paint or appearance concerns, advise your dealer as soon as possible. Your owner manual has instructions regarding the care of these items.

Vehicle Operation and Care

Considering the investment you have made in your GMC, we know you will want to operate and maintain it properly. We urge you to follow the maintenance instructions in your owner manual.

If you have questions on how to keep your vehicle in good working condition, see your GMC dealer, the place many customers choose to have their maintenance work done. You can rely on your GMC dealer to use the proper parts and repair practices.

Maintenance and Warranty Service Records

Retain receipts covering performance of regular maintenance. Receipts can be very important if a question arises as to whether a malfunction is caused by lack of maintenance or a defect in material or workmanship.

A "Maintenance Record" is provided in the maintenance schedule section of the owner manual for recording services performed.

The servicing dealer can provide a copy of any warranty repairs for your records.

Chemical Paint Spotting

Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and adhere to painted surfaces on your vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and/or small irregular dark spots etched into the paint surface.

Although no defect in the factory applied paint causes this, GMC will repair, at no charge to the owner, the painted surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles of purchase, whichever comes first.

Warranty Coverage -- Extensions

Time Extensions : The New Vehicle Limited Warranty will be extended one day for each day beyond the first 24 hour period in which your vehicle is at an authorized dealer facility for warranty service. You may be asked to show the repair orders to verify the period of time the warranty is to be extended. Your extension rights may vary depending on state law.

Mileage Extension : Prior to delivery, some mileage is put on your vehicle during testing at the assembly plant, during shipping, and while at the dealer facility. The dealer records this mileage on the first page of this warranty booklet at delivery. For eligible vehicles, this mileage will be added to the mileage limits of the warranty ensuring that you will receive full benefit of the coverage. Mileage extension eligibility:

Touring Owner Service -- Foreign Countries

If you are touring in a foreign country and repairs are needed, take your vehicle to a GM dealer facility, preferably one which sells and services GMC vehicles. Once you return to the United States provide your dealer with a statement of circumstances, the original repair order, proof of ownership, and any paid receipt indicating the work performed and parts replaced for reimbursement consideration.

Important: Repairs made necessary by the use of improper or dirty fuels and lubricants are not covered under the warranty. See your owner manual for additional information on fuel requirements when operating in foreign countries.

Warranty Service -- Foreign Countries

This warranty applies to GM vehicles registered in the United States and normally operated in the United States or Canada. If you have permanently relocated and established household residency in another country, GM may authorize the performance of repairs under the warranty authorized for vehicles generally sold by GM in that country. Contact an authorized GM dealer in your country for assistance.

Important:  GM warranty coverages may be void on GM vehicles that have been imported/exported for resale.

Original Equipment Alterations

This warranty does not cover any damage or failure resulting from modification or alteration to the vehicle's original equipment as manufactured or assembled by GM. Examples of the types of alterations that would not be covered include installation or use of any non-GM parts, accessories, and materials, or the cutting, welding, or disconnecting of the vehicle's original equipment parts and components.

Recreation Vehicle and Special Body or Equipment Alterations

Installations, or alterations to the original equipment vehicle, or chassis, as manufactured and assembled by GM, are not covered by this warranty. The special body company, assembler, or equipment installer is solely responsible for warranties on the body or equipment and any alterations to any of the parts, components, systems, or assemblies installed by GM. Examples include, but are not limited to, special body installation, such as recreational vehicles, the installation of any non-GM part, cutting, welding, or the disconnecting of original equipment vehicle or chassis parts and components, extension of wheelbase, suspension, and driveline modifications, and axle additions.

Pre-Delivery Service

Defects in the mechanical, electrical, sheet metal, paint, trim, and other components of your vehicle may occur at the factory or while it is being transported to the dealer facility. Normally, any defects occurring during assembly are identified and corrected at the factory during the inspection process. In addition, dealers inspect each vehicle before delivery. They repair any uncorrected factory defects and any transit damage detected before the vehicle is delivered to you.

Any defects still present at the time the vehicle is delivered to you are covered by the warranty. If you find any defects, advise your dealer without delay. For further details concerning any repairs which the dealer may have made prior to you taking delivery of your vehicle, ask your dealer.

Production Changes

GM and GM dealers reserve the right to make changes in vehicles built and/or sold by them at any time without incurring any obligation to make the same or similar changes on vehicles previously built and/or sold by them.
