GMC Extended Warranty: Cost, Coverage and Plans

GMC extended warranty coverage

GMC’s official extended warranty coverage is called a GMC Protection Plan. These plans run concurrently with your factory warranty coverage, and they can be purchased for new or pre-owned GMC vehicles.

For context, all GMC factory warranties include 3 years/36,000 miles of bumper-to-bumper coverage and 5 years/60,000 miles of powertrain coverage. So, if you purchase an 8-year/100,000-mile Platinum plan for a brand-new GMC vehicle, you’ll effectively extend your 3-year/36,000-mile factory warranty by 5 years/64,000 miles.

GMC extended warranty plans

GMC extended warranty plans come in three coverage options: Powertrain, Silver and Platinum. Powertrain plans are available with terms of up to 8 years/120,000 miles while Silver and Platinum plans come in terms of up to 8 years/100,000 miles. Plan deductibles start at $0.

Powertrain plans cover around 200 parts, and Silver plans cover more than 400 parts. The Platinum plan provides the most comprehensive coverage, covering up to 1,500 parts on your vehicle. It’s an exclusionary warranty, meaning it’ll cover all vehicle parts except any that are listed as exclusions in the contract.

Here’s a breakdown of what each GMC Protection Plan covers:

GMC extended warranty plans for used vehicles

GMC’s extended warranty plans are also available to purchase for certified pre-owned (CPO) GMC vehicles. However, GMC doesn’t disclose which of its Protection Plans are available for its CPO vehicles, so you may need to contact a dealer to learn what your options are. Plan options and terms may vary depending on the CPO vehicle you’re interested in.

Note that all CPO GMC vehicles that are less than 10 model years old and 100,000 miles already come with a 12-month/12,000-mile bumper-to-bumper warranty. For CPO GMC vehicles that are more than 10 model years old but less than 15 model years old, or more than 100,000 miles but less than 150,000 miles, you’ll get a 30-day/1,000-mile powertrain warranty.

GMC extended warranty benefits

GMC extended warranty benefits include:

GMC extended warranty cost

GMC extended warranty costs tend to be between $3,400 and $4,000 total, according to our research. For context, the average extended auto warranty costs around $1,000 per year of coverage for a bumper-to-bumper plan. That means GMC Protection Plans tend to range from slightly-below-average costs to average costs.

GMC Protection Plan costs

We collected GMC Protection Plan costs from multiple GMC dealerships. Keep in mind that the term starts from when the vehicle was brand new. So, a 7-year/70,000-mile warranty on a 2023 Sierra 2500HD only really extends the factory warranty by four years or 34,000 miles.

• GMC Yukon

GMC vs. third-party extended warranty costs

GMC third-party extended warranty costs tend to be similar to GMC extended warranty costs, though prices vary by provider. Third-party extended warranty companies tend to offer similar base coverage, though they may offer add-on coverage that you can’t get with an official plan.

We collected quotes from olive and Endurance for the same two GMC vehicles, and we chose plans that were similar to GMC’s Platinum 7-year/100,000-mile warranty.

While our quotes for the GMC Acadia were similar across all three warranty providers, olive offered a much lower quote than the others for the GMC Sierra 2500HD. That’s why getting multiple quotes from dealers and third-party companies can be a smart move.

GMC extended warranty pros and cons

Before purchasing a GMC extended warranty, compare the pros and cons:

GMC extended warranty terms and conditions

GMC’s extended warranty terms and conditions tend to be standard for the auto warranty industry.

Maintenance requirements

To keep your warranty active, GMC requires you to perform all recommended maintenance as outlined in your owner’s manual. Also, make sure you keep your receipts for all maintenance. Warranty providers typically deny claims if you can’t provide documentation of regular maintenance.

Preexisting conditions

As with almost all extended warranties, your GMC Protection Plan will not cover breakdowns or issues that occurred before the warranty period.

For pre-owned vehicles, it can help to get your GMC inspected by the dealer who sells you the warranty, which should cost around $200, so you’ll have proof of what was (and wasn’t) an issue with your vehicle before you purchased your extended warranty.

Coverage exclusions

Standard exclusions for most warranties apply, which means your GMC Protection Plan won’t cover:

• Wear-and-tear items meant to wear out over time, like brake pads and clutches

• Breakdowns caused by negligence, abuse, neglect or lack of maintenance

• Aftermarket parts or issues caused by them

For Powertrain and Silver plans, only the components specifically listed in the contract are covered. For Platinum plans, some components that are excluded include:

• Friction clutch disc

• Pressure plate and clutch release bearing

• Body parts and panels

• Glass, trim, moldings, upholstery and paint

• Lights, fuses, bulbs and filters

• Heater and radiator hoses

• Exhaust systems

• Catalytic converters

Cancellations and refunds

You can cancel your GMC Protection Plan for a full refund within 30 days if you haven’t submitted a claim. If you have submitted a claim, or if it's been more than 30 days, you can cancel for a prorated refund minus a $50 processing fee.

How to buy a GMC extended warranty

To buy a GMC extended warranty, you’ll generally need to purchase a GMC Protection Plan from a dealer. For CPO GMC vehicles, you may be able to purchase a GMC Protection Plan online when you buy a vehicle through CarBravo, which is GM’s used vehicle certification program for GMCs, Chevrolets and Buicks. If you’re unable to buy a vehicle or plan online, you’ll need to contact the dealership that’s selling the vehicle.

Here’s how you can generally buy a GMC extended warranty:

1. Check your vehicle’s eligibility

GMC Protection Plans typically must be purchased before your factory warranty expires, and you must have at least 30 days or 1,000 miles remaining on your factory warranty, according to GMC’s website. However, GMC also states that plans are generally available for vehicles of up to eight years or 100,000 miles.

2. Compare quotes and options from GMC dealers

Since GMC Protection Plans are sold through dealerships, prices can vary. Ask each dealer for the same plan tier, deductible and term that you’re interested in so you can compare quotes fairly.

3. Compare dealer quotes with third-party warranty options

It helps to also collect quotes from third-party extended warranty providers to see if you may be able to get similar coverage for a lower price.

4. Review sample contracts

Ask to review a sample contract or plan documents from each dealer or provider. Read them carefully so you understand what’s covered, what’s excluded, how claims work and what maintenance records you’ll need to keep.

5. Negotiate the price

Dealers may mark up the cost of a GMC Protection Plan. If you’ve received lower quotes from other GMC dealers or third-party warranty providers, use them as leverage to try to secure a better price or additional benefits.

We have also had problems with the computer system of the car[,] and the dealership had to call GM directly and have an engineer help them repair the issue.”

“This is the worst and most unreliable car I have ever purchased,” Steven H Riley said. “I have reached out to my dealership along with General Motors with absolutely no resolution. [...] At 80,000 miles[,] we have had 2 engines. This would be the 3rd.”
