A variety of warranties cover your new GMC. These warranties can initially seem confusing, so as your GMC dealer, we want to tell you about your GMC warranty and the other specialized warranties that come with your new vehicle. 

From Your GMC Dealer: What’s Included in Your 2024 GMC Warranty 

Standard Warranties 

Each GMC has five major warranties and three additional automatic benefits. Combining all of them gives you one of the best protection guarantees available. Let’s take a dive into these warranties and see what they offer. 

Bumper-to-Bumper Limited Warranty 

This warranty protects all components and systems in your vehicle against any unexpected problem due to material or workmanship issues. It is valid for three years/36,000 miles. In addition, your tires are protected against any defects during the warranty period. 

Excluded items include general wear and tear, tire damage from abrasion, routine maintenance, and any damage due to an accident or unauthorized alternations. 

Powertrain Limited Warranty 

The powertrain includes your vehicle’s most complex, expensive, and hardest-working systems. This warranty protects your engine, transmission, and drivetrain against factory-related issues. Some of the vital components covered by this warranty include the engine block, oil pump, transmission mounts and gaskets, and the propeller and axle shafts. 

Items that are not covered include your radiator, sensors, and wiring. 

Corrosion Protection 

Your GMC has comprehensive protection against corrosion and, if correctly maintained, will never corrode. If your car body or sheet metal exhibits any signs of corrosion within the first three years/36,000 miles, this damage will be repaired for free. 

Rust-Through Protection 

Rust-through is rust that eats completely through metal and forms a hole. This warranty protects you for six years/100,000 miles against this form of damage. 

Additional Benefits 

GMC offers even more by providing several invaluable benefits that complement your warranties. We’ve included the main highlights below. 

Roadside Assistance 

Got a flat? Battery let you down? GMC provides 24/7 roadside assistance for these and a range of possible issues. If you’re stuck on the side of the road, expert technicians will arrive and provide you with a range of services. These include towing to an authorized dealership, vehicle unlocking, emergency fuel delivery, and replacing a flat tire. 

Courtesy Transport 

It’s possible that a warranty repair might not be completed on the same day. If this happens, GMC provides for your transport needs while your vehicle is in the shop. You can choose between alternative transportation or reimbursement for your transport expenses. Your car manual provides all this information in detail. 

First Maintenance Free 

Your first maintenance trip is already covered as soon as you take delivery of your GMC. During your first year, visit your friendly dealer and receive a multipoint inspection, oil change, and tire rotation for free.
