GMC trucks come with a powertrain warranty that offers valuable protection for critical components. If you bought your truck new, this warranty can provide coverage for an extended period. To fully take advantage of this protection, you must understand what’s included in the warranty. In this guide, we’ll break down the components covered, the services provided, as well as the exclusions and limitations. Plus, we’ll share tips on how to maximize the benefits of your GMC powertrain warranty.
The GMC Powertrain Warranty
Typically, a GMC powertrain warranty covers three main components: the engine, the transmission, and the drive systems. The warranty covers any necessary repairs or replacements of the covered components due to defects in materials or workmanship and can also include towing to the nearest GMC dealer.
Engine Coverage
The engine has a myriad of components that could potentially fail. A GMC powertrain warranty covers all internally lubricated parts, engine oil cooling hoses, and lines. It also includes all mounts, the engine block, cylinder head, manifold, oil pan, oil pump, seals, gasket, turbocharger, supercharger, and timing chain.
Transmission Coverage
The powertrain warranty for your GMC also extends to your truck’s transmission system. This includes all internally lubricated parts, the case, the torque converter, the mounts, the seals, the gaskets, and any electrical components internal to the transmission/transaxle.
Drive Systems Coverage
Your GMC’s drive system, such as the front-wheel drive, all-wheel drive, rear-wheel drive, or four-wheel drive system, is also protected. This coverage extends to all internally lubricated parts, axle shafts, constant velocity joints, front hub bearings, rear hub bearings, seals, gaskets, and final drive housing.
Exclusions and Limitations
The GMC powertrain warranty provides generous coverage, but there are certain exceptions to be aware of. This warranty does not cover damage caused by accidents, misuse of the vehicle, lack of maintenance, alterations, contamination or loss of fluids, or wear and tear items such as brake pads, clutches, tires, and wiper blades. Basically, treat your vehicle right to keep the warranty intact.
Certain time and mileage conditions also limit warranty coverage. Typically, the GMC powertrain warranty lasts for five years or 60,000 miles (whichever comes first). This means coverage expires once you have either passed the five-year mark or driven over 60,000 miles.
Understanding Warranty Terms
Warranty documents can be complex and full of technical language, so you’ll want to familiarize yourself with terms such as “powertrain,” “drive system,” and “internally lubricated parts” to know what everything refers to. That way, you can interpret what is covered and not covered under the warranty.
Making the Most of the GMC Powertrain Warranty
To fully benefit from your warranty, follow GMC’s recommended maintenance schedule and have certified GMC technicians service your truck. Regular upkeep not only ensures the longevity of your truck but also helps avoid voiding the warranty due to neglect or improper care.
Comparison With Other GMC Warranties
Apart from the powertrain warranty, GMC offers other warranties like the bumper-to-bumper limited warranty and corrosion protection warranty. While the powertrain warranty focuses on the engine, transmission, and drive systems, the bumper-to-bumper warranty covers most parts of your truck from front to rear for any factory defects. These additional warranties can be a great investment that you may wish to purchase to supplement your powertrain warranty.
