General Motors Warranty offerings vary across the Buick, Cadillac, Chevrolet, and GMC brands.
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:
| General Motors Brand | Bumper-to-Bumper Warranty | Powertrain Warranty |
|---|---|---|
| Buick | 3 years/36,000 miles | 5 years/60,000 miles |

| Chevrolet | 3 years/36,000 miles | 5 years/60,000 miles |
| GMC | 3 years/36,000 miles | 5 years/60,000 miles |
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.

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

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.
See the table below for a comparison of the factory warranties that General Motors’ competitors offer:
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.
