GMC Warranty Coverage Overview
All new GMC vehicles come with warranty coverage called the GMC Pro Grade Protection program. This coverage comes with multiple warranty protections, including a 3-year/36,000-mile bumper-to-bumper limited warranty and a 5-year/60,000-mile powertrain limited warranty. The GMC warranty automatically transfers to any subsequent owners.
Here’s a breakdown of the GMC warranty for new vehicles:
|GMC Warranty||Term||Coverage Details|
|Bumper-to-Bumper Limited Warranty||3 years/36,000 miles||Covers almost all vehicle components |
when parts fail due to defects in materials or workmanship
|Powertrain Limited Warranty||5 years/60,000 miles||Covers the engine, transmission, drive axle and related components|
|Corrosion Protection||3 years/36,000 miles||Protects body and sheet metal components against corrosion damage|
|Rust-Through Protection||6 years/100,000 miles||Protects body sheet metal panels that rust through (a hole in the metal)|
|Roadside Assistance||5 years/60,000 miles||Provides towing to the nearest GMC dealership, flat tire changes, |
lockout service, emergency fuel deliveries and battery jump-starts
|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
Compared to other vehicle manufacturers, GMC warranty coverage is standard. The bumper-to-bumper warranty is also below-average compared to the Kia warranty or Subaru warranty. However, the GMC warranty does cover your vehicle’s first maintenance visit, which is a unique benefit.
GMC Warranty Exclusions
Regardless of the manufacturer, no warranty will cover every repair. GMC warranty exclusions are as follows:
- Damage due to a collision, misuse or improper maintenance
- Improper fuel
- Chemical damage due to aftermarket products
- Environmental damage
- Wear-and-tear parts
- Routine maintenance
- Aftermarket alterations
GMC Certified Pre-Owned Warranty
Certified pre-owned (CPO) GMC vehicles come with a 6-year/100,000-mile powertrain warranty and a 12-month/12,000-mile bumper-to-bumper limited warranty. This coverage includes roadside assistance.
CPO GMCs must be less than six model years old, have less than 75,000 miles, have a clean title, have a vehicle history report and pass a 172-point inspection. Vehicle failures may still occur, although GMC’s rigorous CPO requirements should give customers peace of mind.
How to Check if You Have a GMC Warranty
Depending on how you purchased your GMC – from an individual rather than from a dealership – the GMC factory warranty may still be in place. With your vehicle identification number (VIN) handy, call a GMC dealership and ask about any GMC warranty coverage remaining. Since the powertrain warranty only lasts five years, this is probably not applicable to older GMC models.
Is an Extended Warranty Worth It for GMC Vehicles?
To determine if you would benefit from an extended GMC warranty, we recommend taking an honest look at your personal finances and your vehicle’s reliability. If you feel comfortable footing the bill for a high-cost repair or plan on selling your vehicle before the factory warranty expires, an extended warranty may not be worth it.
Regarding GMC’s reliability, we turn to RepairPal. The cost-estimation site uses customer reports to track and estimate common vehicle repairs. See a breakdown of RepairPal’s 2021 GMC reliability ratings below:
|RepairPal Factor||GMC Reliability||Industry Average|
|Average Annual Repair Cost||$744||$652|
|Frequency of Repairs||0.28 repairs per year||0.4 repairs per year|
|Likelihood of a Severe Repair||17%||12%|
GMC repair costs are above average, and although you may need to take fewer trips to the repair shop per year than the average driver, the chance your GMC will sustain a severe repair is much greater. To give you a better idea of what you may pay for GMC repairs, we detailed a few commonly reported repairs below.
|GMC Model||Repair||Estimated Cost|
|GMC Envoy||Fuel pump replacement||$666 to $825|
|GMC Envoy||Anti-lock braking system (ABS) control module replacement||$675 to $832|
|GMC Canyon||Blow motor resistor replacement||$65 to $77|
|GMC Sierra 1500||Headlight bulb replacement||$76 to $91|
If you’d rather save money after your vehicle breaks down instead of spend it, we recommend considering an extended car warranty for your GMC.
GMC Extended Warranty Overview
After your GMC factory warranty expires, customers can choose between two GMC extended warranty plans: the Extended Limited Warranty and the Platinum Protection Plan. A GMC extended warranty will protect you from having to pay for covered mechanical failures. Covered parts differ depending on the level of coverage you buy.
GMC Extended Limited Warranty
The GMC Extended Limited Warranty increases your bumper-to-bumper warranty to 5 years/60,000 miles. However, this plan only applies to new vehicles at the time of sale. The coverage is backed by General Motors, does not include a deductible and ensures all repairs are performed by factory-trained technicians.
GMC Platinum Protection Plan
The GMC Platinum Protection Plan is backed by AMT Warranty, a third-party provider, and . acts as exclusionary, bumper-to-bumper protection. Plans can be purchased anytime before your vehicle reaches 80,000 miles. You can choose between the following term lengths:
- 2 years/24,000 miles
- 3 years/36,000 miles
- 4 years/48,000 miles
- 5 years/60,000 miles
GMC extended warranties do not cover every repair. Routine maintenance services and wear-and-tear items like brake pads, wiper blades and shock absorbers are not covered under these GMC warranty plans.
Should You Consider a Third-Party Extended Warranty?
Purchasing a GMC extended warranty from a third-party provider could be the best option if you are the type of driver who:
- Prefers to pay a monthly premium to finance repairs rather than pay for repairs in full
- Want more customizable extended warranty coverage plans than the manufacturer’s options
- Plan monthly budgets
