If you own a GMC vehicle, you may be wondering if a GMC extended warranty is worth it. Like most car manufacturers, GMC provides limited factory warranties with all new vehicles and sells extended warranties to those who desire extra coverage. Before you purchase extended protection, it’s a good idea to compare your options.

Our team of experts will provide you with an in-depth look at the GMC extended car warranty. We’ll also compare GMC to one of the best extended car warranty companies, Endurance, to help you decide which is better for your situation.

GMC Extended Warranty Overview

GMC Extended Warranty Term Limit

5 years/60,000 miles







General Motors Corporation (GMC) offers an extended warranty for bumper-to-bumper coverage. You have the option to lengthen the coverage term to match the powertrain warranty (5 years/60,000 miles). Extended warranty coverage can only be bought at the time you purchase your GM vehicle.

The GMC extended warranty comes with no deductible. All repairs are performed by GMC Certified Service experts who use new, remanufactured, or refurbished parts.

In addition to its extended warranty plans, GMC also offers an extended factory maintenance plan for all vehicles 2019 and newer. The extended factory maintenance plan pays for three maintenance visits (for oil changes, inspections, or tire rotations) on top of the one already included with the factory warranty.

GMC Extended Warranty Exclusions

Exclusions to the GMC extended warranty include:

  • Tire damage
  • Damage due to bedliners
  • Damage due to accident
  • Collision, fire, or theft
  • Misuse of vehicle
  • Alteration or modification
  • Corrosion due to the environment, chemical treatments, or aftermarket products
  • Insufficient maintenance
  • Low-quality fuel

As with the limited GMC warranty, you must bring your car to a GMC dealership for any and all repairs. The GMC extended warranty is not available to vehicles sold in California, Florida, Maine, or Minnesota.

Do You Need GMC Extended Warranty Coverage?

An auto warranty protects you against sudden, expensive repairs and provides peace of mind. A good warranty guarantees you can afford to repair your vehicle after an unexpected breakdown. But for the most reliable makes and models, an extended warranty may not be worth it. Determining the utility of a GMC extended warranty starts with understanding the car you drive.

GMC vehicles are about average when it comes to reliability. For most GMC models, the frequency of repairs tends to be low, though the expense of these repairs can be high. According to RepairPal, repair costs for GMC vehicles average out to $744 per year. The GMC Canyon has the lowest average repair costs, while the Sierra 3500 and Savana 3500 have the highest.

The chart below outlines some common repairs and prices for a 2017 GMC Sierra 1500.

GMC Sierra 1500 Repair

Average Cost

Air conditioning evaporator replacement

$1,015 - $1,328

Spark plug replacement

$230 - $282

Thermostat replacement

$150 - $176

Water pump replacement

$409 - $562

Rack and pinion replacement

$1,459 - $1,840

Headlight bulb replacement

$70 - $86

In addition to average repair costs, consider what is already covered by the factory warranty when assessing the value of an extended car warranty. The factory warranty may already provide the coverage that you want. The value of an extended warranty only kicks in beyond the factory warranty.

If your GMC vehicle is less than three years old and has fewer than 36,000 miles, it is likely still covered by the limited manufacturer warranty. GMC offers warranty coverage for all new and certified pre-owned (CPO) vehicles. It’s worth checking out these types of coverage while trying to decide whether you need a GMC extended warranty.

GMC Factory Warranty

The following benefits are included with the standard GMC manufacturer’s warranty. This protection comes at no extra cost with all new GMC vehicles.

GMC Warranty

Coverage Term


Bumper-to-bumper limited warranty

3 years/36,000 miles

Covers parts and labor to correct any defect in materials or workmanship, as well as towing to the nearest GMC dealership

Corrosion protection

3 years/36,000 miles

Protects body and sheet metal components against corrosion

Powertrain warranty

5 years/60,000 miles

Covers repairs to the engine, transmission, transaxle, transfer case, and drive axle systems

Roadside assistance

5 years/60,000 miles

Provides access to roadside assistance services through Allstate

Courtesy transportation

5 years/60,000 miles

Provides alternate transportation and reimbursement of certain transportation expenses while your vehicle undergoes warranty repairs

Rust-through protection

6 years/100,000 miles

Includes any body sheet metal panel that rusts through

GMC will also pay for your car’s first scheduled maintenance visit. 2017 and 2018 vehicles are covered for two maintenance visits. As far as factory warranties go, GMC’s is fairly comprehensive. Like any factory warranty though, there are exclusions.

GMC Certified Pre-Owned Warranty

GMC certified pre-owned (CPO) vehicles also come with automatic warranty coverage. GMC CPO warranties offer the same protection as factory warranties, but last a bit longer. Coverage includes:

  • 1-year/12,000-mile bumper-to-bumper limited warranty
  • 6-year/100,000-mile powertrain limited warranty
  • Two free scheduled maintenance visits

GMC Platinum Protection Plan

GMC factory and extended warranty products are administered by GMC directly. GMC also offers Platinum Protection, which is administered by third-party provider AMT Warranty Corp. GMC Platinum Protection can be another way to extend GMC coverage, as it has longer coverage terms than the factory warranty. Coverage lengths offered are:
  • 24 months/24,000 miles
  • 36 months/36,000 miles
  • 48 months/48,000 miles
  • 60 months/60,000 miles

Platinum Protection is comparable to a bumper-to-bumper warranty, though slightly less comprehensive. Some covered components include:

  • Engine
  • Transmission
  • Drive axle
  • Turbo/supercharger
  • Transfer case
  • Steering
  • Alternator
  • Select brake components
  • Air conditioning

GMC Extended Warranty Cost

GMC extended warranty costs will depend on numerous factors related to your vehicle such as its age, make, model, mileage, and the dealership you choose. In our 2021 extended warranty survey which polled 1,000 consumers, 45 percent of respondents reported paying between $1,500 and $2,500 for extended warranty coverage.

GMC extended warranty coverage must be purchased at the same time you buy your new car. If you’re using a loan to purchase your new vehicle, your protection plan is likely to be included on your loan, meaning that you will be paying interest on it long term.

Your protection plan is often negotiable, like the price of your car. It's important to do your research to make sure that you're getting the best coverage possible at a great price.

Benefits of a Third-Party Extended Warranty

An alternative to a GMC extended warranty is to purchase a warranty through a third-party provider. Third-party providers like Endurance and CarShield generally offer cheaper coverage than the dealer.

Another benefit to a third-party provider is that you can purchase coverage anytime. A GMC extended warranty must be purchased at the time you buy your vehicle. This is inconvenient for a couple reasons.

After you own a car for a few years, you have a better idea of its reliability. You are in a better position to assess if your car needs an additional two years of warranty protection after the initial three-year warranty expires. Another reason to wait to purchase an extended warranty is that you may end up selling your car before the factory warranty expires.

When you purchase an extended warranty from a manufacturer, the cost of the warranty may be included in your vehicle purchase and rolled into your loan. This means that unless you have a 0 percent annual percentage rate (APR), you will pay interest on the cost of your extended auto warranty.
