Whether you’re looking for a new GMC, thinking of buying one used, or are a current owner, protecting your vehicle should be top of mind. A GMC extended warranty is one way to do so.

While the GMC factory warranty is comprehensive, it’s essential to understand its limitations in order to protect yourself from unforeseen costs after it expires.

Read on for a full breakdown of the GMC warranty and our recommendations for extended warranties. We’ll also explain the differences between GMC extended warranties offered at dealerships and those from the best car warranty companies.

Doing so will give you the most accurate estimate and will help you to answer any questions about the cost of a GMC extended warranty before you make a purchase.

Is A GMC Extended Warranty Worth It?

Whether or not a GMC extended warranty is worth it depends on a variety of factors, including existing coverage, vehicle reliability, maintenance costs, and the quality of the extended warranty itself. 

When looking at the long-term investment you make when purchasing a vehicle, it’s important to consider all possible scenarios. To help you determine whether or not a GMC extended warranty is the right choice, we’ll look at each of these factors in detail. 

GMC Factory Warranty

First, consider your existing coverage when shopping for a vehicle service contract. A GMC extended warranty will only take effect after the original factory warranty expires, so make sure you’re only purchasing essential coverage.

GMC has a relatively comprehensive warranty, but it only lasts for the first few years of vehicle ownership. Below are some details about your GMC manufacturer’s warranty:

GMC WarrantyWhat It Covers
New Vehicle Limited WarrantyGMC provides “bumper-to-bumper” comprehensive coverage for 3 years or 36,000 miles, whichever comes first. This means almost all of the vehicle is protected, with just a short list of exclusions.
Powertrain Limited WarrantyThis warranty covers powertrain components like the engine, transmission, and driveline for 5 years or 60,000 miles.
Corrosion ProtectionGMC offers protection from elemental rust formation on sheet metal for a period of 3 years or 36,000 miles. This protection is designed to protect against rust from the outside moving inside.
Rust-Through ProtectionGMC offers protection from rust and corrosion on sheet metal that spread inside to outside for 6 years or 100,000 miles. This coverage does not include rust from road salts, etc.
Roadside Assistance24/7 roadside assistance is available throughout the 5-year/60,000-mile warranty period.
Courtesy TransportationWhenever warranty repairs are needed, several transportation options and/or reimbursement of certain transportation expenses are available for your convenience.
GMC Factory Warranty Exclusions

Although the GMC factory warranty is comprehensive for a short time, keep in mind that not everything is covered. Typically, a warranty is in place to cover defects in quality, assembly, or workmanship and not things beyond GMC’s control. These factors include:

  • Regular maintenance (oil, tire rotation, etc.)
  • Tire defects (tire manufacturers have their own warranties)
  • Damage caused by neglect
  • Accidents
  • Wear-and-tear items (brake pads, tires, etc.)

GMC Reliability

According to the J.D. Power 2022 U.S. Vehicle Dependability StudySM, GMC ranks 17th out of 32 automakers in initial quality. GMC has traditionally been known for its durability, but certain models have begun to slip in reliability ratings over the years.

The systems that make up GMC models are complex and often quite expensive – leading to potentially hefty repair bills down the line if drivers don’t have proper coverage.

GMC Maintenance Costs

In addition to any existing coverage, you should consider the cost of GMC repairs when deciding if a GMC extended warranty is worth it. Costly repairs can break the bank when paid entirely out of pocket. Because one or two repairs covered by extended coverage can pay for the entire contract cost, a GMC extended warranty often saves drivers money.

Are GMC Parts Expensive?

Let’s take a look at the price of some of the most common replacement parts for GMC cars. According to RepairPal, here are some common repairs and replacement costs for GMC:

  • Radiator fan assembly replacement on a GMC Acadia: $1,021 to $1,131
  • Water pump replacement on a GMC Sierra: $953 to $1,140
  • Head gasket repair on a GMC Yukon: $1,521 to $1,699

GMC Extended Warranty Reviews

In addition to covering all vehicle components and systems, a GMC extended warranty comes with something critical: peace of mind. It’s your protection against having to budget for costly repairs after the warranty expires.

Whether you purchase an extended warranty from GMC or from a recommended reputable extended car warranty company, investing in GMC extended coverage provides protection against costly repair bills. Dealerships will want you to buy a manufacturer’s extended warranty, but it’s good to research all possible options before purchasing.

GMC Aftermarket Warranty

Third-party extended warranty companies are more flexible and offer drivers greater coverage options than automaker warranties. Unlike coverage straight from GMC, many providers will cover vehicles for up to 200,000 miles and offer five or six specific levels of coverage.

Some independent warranty companies also have perks such as roadside assistance, rental car reimbursement, and towing, so you’ll want to read the fine print when comparing policies. According to our survey, the median cost of an extended warranty is $2,458.

After we analyzed these factory plans, we believe that third-party companies like Endurance, CarShield, and CARCHEX offer better extended warranties for GMC owners. These companies provide more customizable plans to fit your budget while offering similar protection to ensure your peace of mind. Plus, coverage can be much less expensive.
