If you’re looking to purchase a new Buick, Cadillac, Chevrolet, or GMC model, you’re likely wondering what a General Motors factory warranty covers and how long it lasts. In this article, we’ll take a deep dive into the factory warranty offered to all General Motors (GM) brands. We’ll also touch on its extended warranties and why you should consider a third-party provider in your search for the best extended car warranty.

Crash Course:

  • General Motors factory warranty coverage provides both bumper-to-bumper and powertrain protection for all new Buick, Cadillac, Chevrolet, and GMC models.
  • Buick, Chevrolet, and GMC have 3 years/36,000 miles of bumper-to-bumper coverage and 5 years/60,000 miles of powertrain coverage
  • Cadillac offers 4 years/50,000 miles of bumper-to-bumper coverage and 6 years/70,000 miles of powertrain protection.
  • Vehicles manufactured under brands by General Motors have lower-than-average reliability rates. An extended warranty from GM or a third-party provider may give you peace of mind over potentially costly mechanical repairs.

General Motors Factory Warranty Coverage

There isn’t just one General Motors factory warranty offered to all new GM vehicle brands. This automaker owns four major brands – Buick, Cadillac, Chevrolet, and GMC – and all have varying terms and conditions for their new car factory warranties. However, these brands offer two main types of coverage for each of their models: bumper-to-bumper warranties and powertrain warranties.

See the table below for a direct comparison between the four General Motors brands:

We encourage you to consult your owner’s manual for the most comprehensive warranty information on what auto warranties come with your General Motors make and model.

Buick Factory Warranty Coverage

Bumper-to-bumper warranty: 3 years/36,000 miles
Powertrain warranty: 5 years/60,000 miles

This coverage comes with both roadside assistance and courtesy transportation. Your first maintenance visit is also covered within the first year of ownership, and it includes a multi-point vehicle inspection, oil change, and tire rotation. Other warranties included with GM’s Buick factory warranty coverage are an emissions control system warranty and rust-through protection.

Cadillac Factory Warranty Coverage

Bumper-to-bumper warranty: 4 years/50,000 miles
Powertrain warranty: 6 years/70,000 miles

Cadillac’s factory warranty has the longest coverage terms that GM offers: four years or 50,000 miles of bumper-to-bumper coverage and six years or 70,000 miles of powertrain warranty coverage. The bumper-to-bumper limited warranty also covers tires and towing to the nearest authorized dealership for repairs.

Other warranties included with Cadillac’s factory warranty coverage include an emissions warranty and rust-through protection. As with other GM-vehicle brand warranties, courtesy transportation and your first maintenance visit are covered. Powertrain coverage also comes with roadside assistance, which includes services like emergency fuel deliveries, battery jump-starts, flat tire changes, and more.

Chevrolet Factory Warranty Coverage

Bumper-to-bumper warranty: 3 years/36,000 miles
Powertrain warranty: 5 years/60,000 miles

Chevrolet’s bumper-to-bumper limited warranty and powertrain warranty coverage are virtually identical to what Buick and GMC offer: three years or 36,000 miles of bumper-to-bumper protection and five years or 60,000 miles of powertrain coverage. Additional warranties include an emission control system warranty, corrosion coverage, and rust-through protection for sheet metal.

Other perks that come with a Chevy factory warranty include a free first-maintenance visit, roadside assistance, and courtesy transportation.

Other warranty coverages falling under GMC’s new vehicle warranty umbrella include an emissions warranty, corrosion protection, and rust-through protection.

General Motors Factory Warranty Exclusions

Exclusions are the items a warranty will not pay for, and the ones found in General Motors factory warranty coverage are standardized across all its brands. These exclusions apply to Buick, Cadillac, Chevrolet, and GMC:

  • Routine maintenance services with the exception of your first visit
  • Noises or vibrations due to normal characteristics of your vehicle model
  • Damage due to an accident, misuse, insufficient maintenance, or vehicle alteration
  • Components such as wiring, sensors, connectors, coolants, hoses, and more

General Motors Warranty Advantages & Disadvantages

General Motors factory warranty coverage isn’t on par with Kia or Hyundai’s industry-leading warranties: five years or 60,000 miles of bumper-to-bumper coverage and ten years or 100,000 miles of powertrain coverage. However, coverage is consistent with other manufacturers like Honda, Jeep, Ford, Toyota, and more.

We appreciate how all General Motors factory warranties are fully transferable to new owners. GM also provides automotive technicians that specialize in the brand’s repairs.

A drawback to General Motors factory warranties is that repair work done at independent shops may not be reimbursed since vehicles need to be diagnosed by a GM dealer to determine eligibility.

General Motors Extended Warranty Options

The below-average reliability coupled with average or above-average repair costs across all General Motors brands may be concerning. However, extended car warranties can offer peace of mind by providing comprehensive protection once your GM factory warranty has expired.

You can purchase a vehicle service contract through a Buick, Cadillac, Chevrolet, or GMC dealership if you’re looking for factory-backed coverage. You can also purchase a warranty plan from a third-party provider.

General Motors Extended Warranties

The extended warranty offerings from Buick, Cadillac, Chevrolet, and GMC are largely the same. They are backed by General Motors, and you’ll find three plan levels available across all brands – the Powertrain, Silver, and Platinum plans. Keep in mind that these plans must be purchased through a dealership. See the table below for more details:

GM Extended Warranty PlanWhat It Covers
PlatinumThe most comprehensive coverage offered and the most similar to a bumper-to-bumper warranty. This adds on to the coverage provided by the Silver plan by protecting high-tech, audio, and navigation systems in your GM vehicle.
SilverThis warranty covers all the parts listed in the Powertrain level of coverage in addition to front suspension, rear suspension, climate control electrical, steering, and brake components.
PowertrainThis plan offers basic coverage that protects your vehicle’s most essential components, including parts associated with the engine, transmission, drive axles, and hybrid/electric systems.

GM advertises its plans as having customizable contract terms and deductibles. Coverage can provide protection for up to 1,500 different parts on your vehicle depending on the plan you choose, and plans run concurrently with active manufacturer warranties.

It’s good to note that you can cancel your GM extended warranty for a full refund within 30 days, and coverage is fully transferable for a $50 fee.

GM Extended Warranty Perks

You’ll find a wide range of perks built into GM’s extended warranty offerings, including:

  • Roadside assistance program
  • Towing services
  • Battery jump-starts
  • Emergency fuel and fluid deliveries
  • Lockout assistance
  • Rental car coverage
  • Trip interruption benefits

Third-Party Extended Warranties

If you’re looking for more flexibility and coverage options for your vehicle, you should consider an extended warranty from a third-party provider. You can purchase coverage from a third-party company at any time, and many providers offer protection plans for older, used cars and cars with over 100,000 miles.

Third-party extended warranty companies also offer extensive benefits similar to those offered through General Motors. These include roadside assistance, towing, trip interruption benefits, rental car coverage, and even maintenance coverage in some instances.

General Motors Factory Warranty: Conclusion

General Motors offers limited bumper-to-bumper and powertrain warranties across Buick, Cadillac, Chevrolet, and GMC that are on par with other manufacturers. The company also has a selection of extended warranties to prolong warranty coverage after the factory warranty expires.

Because GM’s brands aren’t particularly reliable, an extended warranty can help cover repair costs. However, an extended warranty from a third-party provider may be a better value than one from the manufacturer. 

GM Warranty Alternatives

Depending on your coverage needs, a third-party provider can offer more flexibility and convenience, since you don’t need to go through a dealership. Check out some of our favorite extended car warranty providers below.
