GMC, the all-truck and SUV division of General Motors, advertises itself as “Professional Grade.” At the same time, the brand touts luxury in its Denali trim models, and indeed, these vehicles do rival luxury brands for comfort, amenities, tech, and even pricing. But does the GMC extended warranty measure up to that standard?

We think it makes sense to consider buying extended warranty protection for a GMC to get peace of mind after the new vehicle warranty expires. In this review, we’ll compare the GMC warranty to plans from some of the industry’s best extended warranty companies. Before you shop for a new or certified pre-owned (CPO) GMC vehicle, contact a few providers and compare free quotes.

    GMC Extended Warranty Overview

    The GMC Extended Limited Warranty extends vehicle coverage to 5 years/60,000 miles. Unlike many warranties, the GMC extended warranty is a true extension of the new vehicle warranty, with no deductible to pay when you get covered repairs. It’s also available on other General Motors vehicles.

    However, because you must purchase this warranty at the same time you buy the GMC vehicle, it’s a good idea to ask the dealer for pricing before you get into final negotiations on the purchase. Here are some things to keep in mind when considering a GMC extended warranty:

    • You can’t buy the warranty extension after you buy the vehicle.
    • You can’t cancel the extension once you buy it.
    • It is transferable should you sell the vehicle or trade it in.
    • It is not available for certified pre-owned models.

    A Second Choice: GMC Platinum Protection Plan

    Your second choice for a GMC extended warranty is the Platinum Protection Plan. This is a service contract, which some also refer to as an extended warranty. The difference is that a service contract does not cover every single part. This is true of plans sold by car dealers and those sold in the aftermarket.

    This plan has several benefits:

    • You can purchase it when you buy the GMC vehicle or at any time up to 80,000 miles. (You’ll pay a bit more if you purchase it later.)
    • Plan terms are available up to 5 years/60,000 miles (beyond original warranty coverage).
    • Choose between a $0 or $100 deductible. A third choice is a $100 disappearing deductible, which means you do not pay it for repairs done by the selling dealer.
    • You can cancel it at any time. If you cancel within 60 days of purchasing and have filed no claims, you’ll get a full refund. After that, refunds will be prorated minus any claims paid.
    • It’s transferable if you sell the vehicle.

    Pricing For GMC Platinum Protection Plans

    GMC extended warranty costs depend on the model and whether it has two-wheel drive or all-wheel/four-wheel drive. You can price the GMC Platinum Protection Plan right on the GMC website. The price ranges below reflect costs from a 2-year/24,000-mile plan to a 5-year/60,000-mile plan. You can also choose 3-year/36,000-mile and 4-year/48,000-mile terms.

    • 2020 GMC Terrain AWD: $1,845 to $3,427
    • 2020 GMC Sierra 4WD: $1,846 to $3,427
    • 2020 GMC Acadia AWD: $2,019 to $3,850
    • 2020 GMC Yukon 4WD: $2,019 to $3,850

    Those prices would be five percent higher if you choose to pay with an installment plan.

    What The GMC Platinum Protection Plan Covers

    The GMC Platinum Protection Plan covers more than 1,000 components. These make up the major vehicle systems, including:

    • Adaptive cruise control
    • Airbags and safety restraint system
    • Air conditioning/climate control
    • Blind-spot detection and reverse warning systems
    • Drive axle (front-, rear-, or all-wheel drive)
    • Electrical, including OnStar and audio systems
    • Engine
    • Heated seats (if equipped)
    • Ride control suspension (if equipped)
    • Seals and gaskets
    • Steering
    • Transmission

    While the GMC Platinum Protection Plan is comprehensive, there are some things it doesn’t cover, which is common in the industry. Some exclusions are:

    • Battery and battery cable/harness
    • Brake rotors, drums, and pads
    • Certain emission control components
    • Exhaust components (unless listed as a specific covered part)
    • Headlights
    • Key fobs
    • Tire pressure sensors
    • Trim
    • Wheels

    The Platinum Protection Plan states coverage for brakes, but this relates mostly to the braking system and anti-lock components. It does not include rotors and pads, which are considered wear items. You can ask your GMC dealer for details on this plan.

    Do You Need A GMC Extended Warranty?

    When considering whether to buy a GMC extended warranty, it’s helpful to think about what coverage you already have and what to expect from the vehicle’s overall quality and repair costs.

    While not one of the longest warranties, GMC’s warranty does have some strong points. We’ve compared it to the Chevrolet and Cadillac warranties, because GMC vehicles share much in common with both brands.

    2020 GMC

    2020 Chevrolet

    2020 Cadillac

    New Vehicle Warranty

    3 years/36,000 miles

    3 years/36,000 miles

    4 years/50,000 miles

    Powertrain Warranty

    5 years/60,000 miles

    5 years/60,000 miles

    6 years/70,000 miles

    Powertrain Warranty (Diesel)

    5 years/100,000 miles

    5 years/100,000 miles


    Roadside Assistance

    5 years/60,000 miles

    5 years/60,000 miles

    6 years/70,000 miles

    The 3-year/36,000-mile corrosion protection is a pleasant surprise in the GMC warranty. That’s in addition to the 6-year/100,000-mile rust-through warranty. Most brands offer only rust-through warranty coverage (an actual hole through a sheet metal body panel) but not coverage for surface corrosion (which can lead to rust-through).

    GMC also includes the vehicle’s first maintenance visit for free–it’s basically an oil change.

    GMC Reliability

    It’s worth looking at some reasons why you might need added coverage for a GMC vehicle. A widely followed industry measurement for longevity is J.D. Power’s U.S. Vehicle Dependability StudySM. The study indicates the number of problems per 100 vehicles experienced after three years of ownership.

    This is one test where a lower score is better. As reference points, the industry leader in 2021 was Lexus at 81. GMC came in with 143, near the bottom of the list.

    GMC Repair Costs

    Repairs on new vehicles can be expensive, regardless of the brand. You can research potential repair costs for any vehicle at RepairPal. We pulled the following samples for four-year-old GMC vehicles to help determine whether a GMC extended warranty is worth it:



    Estimated Cost

    2017 GMC Acadia

    Replace starter

    $491 to $556

    2017 GMC Terrain

    Replace water pump

    $690 to $899

    2017 GMC Yukon

    Replace cylinder head gasket

    $923 to $1,802

    2017 GMC Sierra

    Replace radiator

    $1,074 to $1,506

    2017 GMC Canyon

    Replace transmission

    $4,079 to $4,398

    If you don’t have the extra cash to cover these repairs, a GMC extended warranty could offset the cost and make the payment schedule more manageable.

    The Bottom Line: More Choices In Extended GMC Protection

    The GMC extended warranty plans from the manufacturer are competitive, but it’s smart to consider all of your options.

    With third-party providers, you’ll often find more plan choices than with GMC, which offers just a couple levels of coverage. You’ll also find more affordable basic plans, as well as high-end plans with much longer coverage terms than GMC offers.
