Whether you are looking for a new GMC, thinking of purchasing one used, or currently own a GMC, protecting your investment should be top of mind. A GMC extended warranty is one way to do so.

New GMC vehicles come with an industry-standard, no-deductible, bumper-to-bumper warranty that’s in effect for 3 years or 36,000 miles, whichever comes first. In addition, GM offers a limited 5-year/60,000-mile powertrain warranty, as well as additional limited warranties and services detailed below.

While this industry-standard warranty is comprehensive, it’s important to understand its limitations and other long-term ownership considerations so that you can protect yourself from unforeseen costs after your vehicle’s original factory warranty expires. Our review team has researched the best extended auto warranty providers currently available. We recommend clicking below to get free quotes from the top providers for your GMC vehicle.

Read on for a full breakdown of the GMC warranty and our recommendation for extended warranties. We’ll also fully explain the differences between GMC extended warranties offered at dealerships and those that can be purchased from reputable extended car warranty companies.

GMC Extended Warranty Cost And Terms

A GMC extended warranty for your truck or SUV comes with something almost invaluable: peace of mind. It’s your protection against having to budget for costly repairs on your daily driver after the warranty expires. In many cases, one or two repairs covered by an extended warranty can pay for the entire cost of the warranty.

A key thing to keep in mind when looking at purchasing a GMC extended warranty through a dealership is how you will pay for it. Oftentimes, dealers will include the cost of such plans into the financing of the vehicle – meaning you’re paying interest. This interest can really add up over the course of the loan. Also, these GMC extended warranty plans are limited in what they cover and the length of time that they cover your car. Below is a breakdown of GMC Warranty plan options, their terms, and costs.

GMC Extended Warranty Options

GMC Extended Limited Warranty

GMC offers drivers the option of extending their “bumper-to-bumper” factory warranty during the new car purchase process through an Extended Limited Warranty.

Here are a few key details:

  • Offered only when you purchase your vehicle
  • Is an extension of your factory bumper-to-bumper coverage
  • Pushes coverage to 5 years/60,000 miles
  • Not available in California, Florida, Maine, or Minnesota
  • Pricing available only through dealerships
  • Transferable to a new owner if you sell your vehicle

GMC Platinum Protection

GMC also offers its customers a vehicle service contract administered by third-party company AMT Warranty Corp. This GMC extended warranty option can be purchased from a dealer or online, and it can and broken up into monthly payments or paid for upfront.

Here’s what you need to know:

  • Offered on new, used, and currently owned GMC vehicles
  • Maximum contract length is 5 years/60,000 miles
  • Not quite bumper-to-bumper coverage
  • Deductible required to receive the repair services
  • Transferable to new owners
  • Two levels of coverage available: Platinum (exclusionary) and Silver (stated component)

GMC Platinum Protection Cost

Pricing for GMC’s Platinum Protection Plan varies based on vehicle type, location, and coverage length.

We pulled a few pricing examples for a 2019 GMC Acadia with all-wheel drive in Nevada:

  • 24 months/24,000 miles: $1,543
  • 36 months/36,000 miles: $2,451
  • 48 months/48,000 miles: $3,197
  • 60 months/60,000 miles: $3,153

After our analysis of these factory plans, we believe that third-party companies like EnduranceCarShield, and CARCHEX offer owners much more customization and comprehensive coverage choices. These companies offer more customizable plans to fit your budget while offering the protection to help ensure your peace of mind. Plus, coverage can be much less expensive.

Is A GMC Extended Warranty's Cost Worth It?

A GMC extended warranty for your truck or SUV comes with something almost invaluable: peace of mind. It’s your protection against having to budget for costly repairs on your daily driver after the warranty expires. In many cases, one or two repairs covered by an extended warranty can pay for the entire cost of the warranty.

According to RepairPal, here are some common repairs on GMC Vehicles:

  • Transmission replacement on a 2015 GMC Acadia is $4,503 to $4,589.
  • Water pump replacement on a 2014 GMC Sierra is $556 to $621.
  • Head gasket repair on a 2015 GMC Yukon is $968 to $2,659.

Take a look at the 2015 GMC Yukon Infotainment System – the part alone is $1,395, and remember, it does not include installation, which will run an additional $250–$350.

You should also consider your existing coverage when shopping for a vehicle service contract. A GMC extended warranty will only take effect after the factory warranty expires, so make sure you’re not purchasing nonessential coverage.

Modern Car Systems Require Long-Term Protection

Modern vehicles are incredible machines that contain dozens and dozens of computer-controlled systems that are instrumental to the daily operation of a vehicle. Vehicles now stop themselves to avoid accidents, call for help when needed, and even allow users the ability to browse the internet while inside.

Beyond that, a vehicle’s central control system operates your vehicle’s entertainment systems, air conditioning, and even (if so equipped) your vehicle’s heated or cooled seats. These systems are incredibly complex and incredibly expensive – leading to potentially hefty repair bills down the line if you don’t have proper coverage.

Consumer Reports includes a section for “In-Vehicle Electronics” in its reliability studies and notes the continued staggering rise in complaints from consumers.

Why does this all matter? Well, when looking at the long-term investment you make when purchasing a vehicle, it’s important to consider all possible scenarios in order to protect your investment. A GMC extended warranty will provide extra peace of mind after your factory warranties expire and can cover all vehicle components and systems – not just the systems that move the car down the road.

According to the J.D. Power 2020 U.S. Vehicle Dependability StudySM, General Motors Company ranks in the 28th out of 32 in initial quality, placing it in the lower third of vehicle reliability among other manufacturers. Traditionally, GMC has been known for its reliability and durability. However, in recent years, it has begun to slip in reliability ratings, especially among its popular SUV offerings.

What Does GMC Warranty Cover?

As we mentioned above, it’s best to consider the coverage your GMC already has. The manufacturer offers new car owners a fairly comprehensive factory warranty that provides financial security against unexpected repairs, but only for the first few years of ownership. Below, we’ve outlined the details of the GMC factory warranty.

GMC Warranty Coverage

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.

Courtesy TransportationWhenever warranty repairs are needed, several transportation options and/or reimbursement of certain transportation expenses are available for your convenience.

What Isn’t Covered Under Your GMC Factory Warranty?

Although the GMC factory warranty is comprehensive for a short period of time, it’s important to know not everything is covered. Typically, a warranty is in place to cover defects in quality, assembly, or workmanship and not things beyond the control of GMC, such as:

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

Best Extended Car Warranty Companies For Your GMC

A GMC extended warranty from the manufacturer may not be the best choice for every driver. Often, third-party providers can offer more vehicle service contracts to choose from, additional in-contract repair facilities, and more affordable coverage overall. See below for our top-recommended providers.

Endurance: Best Coverage

In our review of the best extended warranty providers, Endurance came out on top. The company offers direct-to-consumer extended warranties. This means that, unlike many third-party brokers in the extended warranty industry, warranty services all come directly from Endurance, and the company handles all claims directly. There’s no middleman or underwritten provider.

Excellent customer service during the quote and claims processes is a focus of many positive Endurance warranty reviews. Just a few benefits include:

CarShield: Best Value

CarShield offers the type of flexibility that modern consumers demand and has proved to be an increasingly popular choice since opening its doors in 2005. In fact, over 1 million consumers have trusted their vehicle protection to CarShield. Its extended warranty plans span six levels of coverage, from comprehensive bumper-to-bumper coverage to coverage for basic powertrain components.

CarShield has an incredible number of online reviews from customers all over the country. Based on our own comprehensive research, here are a few of the perks:
