GM factory warranties lengthen the life of vehicles from its four automobile brands: Buick, Cadillac, Chevrolet and GMC. However, you can also get additional coverage or extend your factory bumper-to-bumper warranty. These plans offer a variety of different coverages; however, some of them can only be added when you purchase your vehicle.

Bottom Line

What is GM Warranty?

“GM Warranty” isn’t an actual company; it’s an umbrella term for offerings from General Motor’s automotive brands: Buick, Cadillac, Chevrolet and GMC. Like most automakers, these brands provide warranties for their new vehicles, but they also have additional warranty options available beyond what’s included from the factory. These protection plans are generally only available through participating dealerships, though.

GM extended warranty coverage

As a GM customer, you have several extended warranty options through your dealership, including:

An Extended Limited Warranty
A Platinum Protection Plan
Gap coverage
Pre-paid maintenance (various levels)
Tire and wheel protection (various levels)
Appearance Guard
XS Wear Lease Protection
Advanced Lease Protection.

When you purchase a new GM vehicle, you can pay more to extend your limited warranty's coverage for two years or 20,000 - 24,000 miles, depending on the make of your vehicle.

Brand	Standard bumper-to-bumper coverage	Extended Limited Warranty coverage
Chevrolet	3 years or 36,000 miles	5 years or 60,000 miles
GMC	3 years or 36,000 miles	5 years or 60,000 miles
Buick	3 years or 36,000 miles	5 years or 60,000 miles
Cadillac	4 years or 50,000 miles	6 years or 70,000 miles

However, you can also choose to buy a Platinum Protection Plan at your dealership through a company called AMT Warranty. These vehicle service contracts are endorsed by GM’s brands, but they technically cover different things than your existing warranty. You can purchase a Platinum Protection Plan can be added at the time of purchase or up to 84 months or 100,000 miles down the road.

GM Warranty benefits

While your GM vehicle is covered by a Powertrain Limited Warranty or a Hybrid Specific Warranty, you qualify for the company’s 24-Hour Roadside Assistance Program. This includes benefits such as:

Emergency towing
Lockout service
Flat-tire changes
Emergency fuel delivery
Jump-starts
Mobile EV charging

GM extended warranty cost

The cost of GM extended warranty coverage depends on which plan you choose. Plans range in price, but there’s not much pricing information available online besides the Platinum Protection Plan. Chevrolet, Buick, GMC and Cadillac all offer a Find My Price tool on their websites that provides quotes for a Platinum Protection Plan based on your vehicle.

As an example, we gathered quotes for a Platinum Protection Plan on a 2021 Buick Enclave in Texas and shared them below.

Coverage term	Single-payment price*	Monthly cost*
24 months / 24,000 miles	$2,227.75	$160.42 for 14 months
36 months / 36,000 miles	$2,963.05	$143.80 for 21 months
8 months / 48,000 miles	$3,502.65	$170.85 for 21 months
60 months / 60,000 miles	$3,683.15	$179.90 for 21 months

It’s worth noting that paying the entire amount upfront offers a 5% savings, and monthly payment plans require a down payment of roughly $99. If you’re interested in what a Platinum Protection Plan will cost for your vehicle, use the Find My Price tool on your automaker’s website to get a quote for yourself.

GM Warranty FAQ

Does GM offer an extended warranty?

Yes, GM offers various additional protection plans, including an extension of your limited warranty and vehicle service contracts through AMT Warranty. You can only extend your original warranty at the time of purchase, but you can opt for a vehicle service contract when you purchase your vehicle or up to 84 months or 100,000 miles later.

What is the standard GM warranty?

At the time of publishing, all new GM vehicles come with a powertrain warranty and a shorter bumper-to-bumper warranty. Chevrolet, Buick and GMC vehicles come with 3-year/36,000-mile bumper-to-bumper warranties, but Cadillacs come with a 4-year/50,000-mile warranty.

How does a GM warranty work?

GM warranties generally work like other auto warranties:

Depending on what type of warranty you have, GM pays for most or all of your vehicle's covered repairs at a participating dealer. However, you may have to pay a deductible with certain plans.
Your warranty has two main limits: one in years and one in miles. Your warranty coverage ends if you meet either condition (i.e., if the amount of time has expired or you exceed the mileage limit).

There are lots of other criteria for warranty coverage and limits, so it’s worth familiarizing yourself with the details on your GM brand’s website.

What is covered in a GM bumper-to-bumper warranty?

Broadly speaking, GM's bumper-to-bumper warranties cover any repairs, including parts and labor, made to correct defects in materials or workmanship. Examine your GM contract for specific coverage details.

Is a GM extended warranty worth it?

Whether a GM extended warranty is worth it depends on your vehicle, how much the warranty will cost you and the coverage it provides. Vehicles are more likely to need repairs as they age, and car repairs can be expensive. However, an extended warranty is only a value if you put it to use. Consider your budget, risk level and future financial position to see whether a GM warranty makes sense for you.
