The bumper-to-bumper New Vehicle Limited Warranty covers vehicles registered in the U.S. and Canada from the date the vehicle is first delivered until it reaches 3 years or 36,000 miles (whichever occurs first). It covers the vehicle from bumper to bumper on any vehicle defect related to materials or workmanship. For further details, refer to your GMC Warranty Manual under "What Is Covered" and "What Is Not Covered."
GMC vehicles are designed and built to resist corrosion. All body and sheet metal components are warranted against rust-through corrosion for 6 years/100,000 miles (whichever comes first). Application of additional rust-inhibiting materials is neither necessary nor required under the Sheet Metal Coverage. GMC 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. See your GMC dealer for terms of this limited warranty.
While most customers prefer to have this type of work performed at their selling dealer, service can be performed at any GMC dealership.
Repairs must be performed by an Authorized GMC dealer, except in a situation where you are significantly inconvenienced and when a covered part or a GMC dealer is not reasonably available to the vehicle owner. It’s in your best interest to take your GMC vehicle to a GMC dealer for all repairs since they are the most knowledgeable about your vehicle.
