GMC Warranty Overview

As soon as you drive your new GMC off the lot, it’s covered by a GMC warranty called the GMC Pro Grade Protection plan. This includes a range of coverage such as a 3-year/36,000-mile bumper-to-bumper warranty and a 5-year/60,000-mile powertrain warranty.

Here is a breakdown of the GMC coverage that comes with all 2020 and newer vehicles:

GMC Warranty Term Length Coverage Details
Bumper-to-Bumper Limited Warranty 3 years/
36,000 miles
Covers almost all vehicle failures due to defects in materials or workmanship
Powertrain Limited Warranty 5 years/
60,000 miles
Covers the engine, transmission,
drive axle, and related components
Roadside Assistance 5 years/
60,000 miles
Provides towing to the nearest GMC dealership after a mechanical breakdown
Courtesy Transportation Coverage 5 years/
60,000 miles
Covers a rental car or alternative transportation when your GMC is in the shop for a covered repair
Corrosion Protection 3 years/
36,000 miles
Protects all body and sheet metal components against corrosion
Rust-Through Protection 6 years/
100,000 miles
Protects body sheet metal panels
that rust through

These are typical term lengths for a factory warranty. One noteworthy detail about the GMC warranty is that repairs may be performed using new, remanufactured, or refurbished parts. Many manufacturer warranties guarantee the use of new parts for repairs. However, the GMC warranty also covers your vehicle’s first maintenance visit, which is a positive benefit.


GMC Warranty for Certified Pre-Owned Vehicles

Certified pre-owned (CPO) GMC vehicles come with a factory-backed, 6-year/100,000-mile powertrain warranty and a 12-month/12,000-mile bumper-to-bumper limited warranty.

In order to qualify for a CPO GMC warranty, a vehicle must be less than six model years old, have less than 75,000 miles on it, have a clean title, submit a vehicle history report, and pass a 172-point inspection. Although these are thorough regulations, vehicle failures may still happen, which is when your CPO GMC warranty will come in handy.

Do You Need an Extended GMC Warranty?

To determine if you would benefit from an extended GMC warranty, we recommend assessing your personal finances and your vehicle’s reliability. You have many options when it comes to saving money on car repairs.

Purchasing a GMC extended warranty or a vehicle service contract from a third-party provider could be the best option if you would prefer to pay a monthly premium to finance repairs rather than pay for repairs in full after a breakdown.

Another way to prepare financially for unexpected breakdown repairs is to build up a savings account exclusively for car repairs. If you’re independently wealthy or already have a repair savings account, an extended car warranty might not be needed.

It’s also a good idea to look into GMC’s reliability through a source such as RepairPal. See a breakdown of RepairPal’s most recent GMC Reliability Rating below:

  GMC Reliability Industry Average
Annual Repair Cost $744 $652
Frequency of Repairs 0.3 repairs per year 0.4 repairs per year
Likelihood of Needing Severe Repairs 17 percent 12 percent

As you can see, GMC is above average in terms of annual repair costs, and although you may need to take fewer trips to the repair shop per year than the average driver, the chance your GMC will need a major repair is much higher. Based on this data, an aftermarket car warranty could be a great way to help you save hundreds if not thousands of dollars when repairs arise.

GMC Extended Warranty Overview

If you want extended coverage that’s similar to your original GMC warranty, consider purchasing a vehicle service contract from the manufacturer. A GMC extended warranty could protect your vehicle for an additional 5 years/60,000 miles after your factory warranty ends.

There are two GMC Protection Plans to choose from, and you can purchase coverage even after your original GMC warranty expires, which is a nice perk. Plans can be purchased anytime before your vehicle reaches 7 years/100,000 miles, and your vehicle can be covered for a total of 12 years/160,000 miles.

The GMC extended warranty will protect you from having to pay the costs of parts and labor for certain mechanical failures. Routine maintenance services and wear-and-tear items like brake pads, wiper blades, and shock absorbers are not covered under these GMC warranty plans.

Benefits of a Third-Party GMC Warranty

A GMC extended warranty is nice in that it has a higher 12-year/160,000-mile coverage limit and can be purchased after your factory GMC warranty expires. However, there are only two protection plans to choose from. A third-party warranty from one of the industry’s best extended car warranty companies may offer better protection.

Here are some other benefits to choosing a third-party vehicle service contract:

  • Coverage can last as long as 15 years or 250,000 miles, depending on the provider and plan you choose.
  • Reputable extended car warranty companies typically offer between three and six plans to choose from.
  • Third-party plans aren’t subject to dealer markups, so they’re often cheaper than manufacturer-backed plans.
  • Instead of always having to take your vehicle into a GMC dealership for repairs, you can visit any licensed repair shop, including dealerships.

If you want to explore your extended warranty options, we recommend starting with our top providers: Endurance, CARCHEX, and Protect My Car. These providers have the highest ratings and most comprehensive coverage in the industry.
