Understanding your Buick warranty coverage could give you added peace of mind on the road. A Buick warranty guarantees that any damage due to defects in material or workmanship will be paid for by the manufacturer, potentially protecting your finances from a number of out-of-pocket expenses within the first few years of your new car’s life.

This review dives into the Buick warranty that comes with all of the automaker’s new vehicles, as well as extended warranty coverage options for new and Certified Pre-Owned (CPO) Buick vehicles. We’ll help you decide whether extending your Buick warranty with coverage from one of the best extended car warranty companies is the right choice for your vehicle.

Buick Warranty Overview

The Buick warranty covers 2020 or newer vehicles from bumper to bumper for 3 years or 36,000 miles, whichever comes first. For 2018 and 2019 Buicks, bumper-to-bumper coverage lasts 4 years or 50,000 miles.

That’s not the only part of the Buick factory warranty, though. At the time of vehicle purchase, your new Buick is covered by several manufacturer warranties. New vehicle limited warranty coverage for 2018 and newer Buicks is outlined below:

Buick Model YearBuick WarrantyTerm Length

Courtesy Transportation6 years/70,000 miles
Rust-Through Coverage6 years/unlimited miles
eAssist Coverage (2018 only)8 years/100,000 miles

Here’s a further breakdown of the parts that each Buick warranty plan covers:

  • Bumper-to-Bumper Limited Warranty: Provides the highest level of warranty protection for your car, paying for repairs needed due to defects in materials or workmanship
  • Powertrain Limited Warranty: Provides protection for your Buick vehicle’s most vital parts, including the engine, transmission, and drive axle
  • Corrosion Coverage: Covers all body and sheet metal corrosion damage
  • 24/7 Roadside Assistance: Includes roadside services and towing to the nearest Buick dealership if your car breaks down
  • Courtesy Transportation: Provides rental car reimbursement or alternate transportation while your Buick is in the shop overnight for a covered repair
  • Rust-Through Coverage: Covers sheet metal panels that rust all the way through, creating holes
  • eAssist Coverage: Coverage for eAssist hybrid technology in certain vehicles

Not all types of damage are covered by the warranty for new Buick vehicles. Here are some exclusions:

  • Accidents
  • Misuse or alteration of the vehicle
  • Insufficient or improper maintenance
  • Contaminated or poor-quality fuel

These exclusions are standard in the industry.


Is A Used Buick Covered Under Warranty?

Each CPO Buick comes with a warranty that gives drivers up to 6 years/100,000 miles of powertrain coverage (starting from the car’s original in-service date) and 1 year/12,000 miles of bumper-to-bumper coverage.

The CPO Buick powertrain coverage protects the engine, transmission, transaxle, and other related parts. The bumper-to-bumper CPO Buick warranty covers most major vehicle systems, including the heating, air conditioning, and steering. There is no deductible for either warranty.

All CPO Buick warranties also come with two complimentary scheduled maintenance visits with oil and oil filter changes, tire rotations, and inspections within 2 years/24,000 miles, as well as roadside assistance and courtesy transportation coverage for the duration of your powertrain warranty.


Do You Need An Extended Buick Warranty?

To determine if a Buick extended warranty is right for you, we recommend honestly assessing your finances and your vehicle’s reliability. You can find out more about Buick repair costs and reliability scores on RepairPal, a repair-cost estimation website that also releases annual industry-wide reliability ratings.

In RepairPal’s 2021 Reliability Rating, Buick earned a 3.5 out of 5.0, placing it 13th out of 32 car brands. This rating was based on the annual average cost of repairs, the frequency of trips to the repair shop per year, and the likelihood of needing severe repairs. “Severe,” in this case, refers to a repair that costs three times the average annual repair cost of all models.

Here’s how Buick ranked in RepairPal’s 2021 Reliability Rating compared to the average across all automakers:

Buick Rating

Average Across
All Car Brands

Average Annual Repair Cost$608$652
Frequency of Repair Visits0.3 times per year0.4 times per year
Chance of a Severe Repair13%12%

As you can see, the average annual repair cost and frequency of repair facility visits are less than average for Buicks, but the likelihood of severe repairs is slightly higher. It could be worth it to look into your extended Buick warranty options if you want to save money on car repair costs in the long run.

Buick Extended Warranty

Owners of new Buicks have the option to purchase the Buick Extended Limited Warranty when they buy their vehicles. This warranty coverage extends the standard bumper-to-bumper factory warranty to 5 years/60,000 miles.

Buick also offers two levels of vehicle service contracts: Silver and Platinum. Customers can choose their plan length from the following coverage terms:

  • 2 years/24,000 miles
  • 3 years/36,000 miles
  • 4 years/48,000 miles
  • 5 years/60,000 miles

The Silver Protection Plan from Buick provides coverage for your car’s major systems, including:

  • Engine
  • Transmission
  • Drive axle
  • Transfer case
  • Steering
  • Electrical system
  • Air bags
  • Brakes
  • Air conditioning
  • Seals and gaskets

The Platinum Protection Plan from Buick gives you bumper-to-bumper coverage, including everything in the Silver Protection Plan and most mechanical and electrical vehicle parts.

Buick Protection Plans also come with the following benefits:

  • Towing and roadside assistance up to $150 per occurrence
  • Rental car reimbursement of up to $40 per day (max $280 per occurrence)
  • Trip interruption reimbursement of up to $200 per day (max $800 per occurrence)

Buick Coverage From A Third-Party Warranty Company

If you’d rather purchase Buck warranty coverage independent of a dealership, opt for coverage from one of the industry’s most reputable extended car warranty companies.

Third-party extended warranties typically provide more customizable coverage options at more affordable rates than a manufacturer-backed warranty. Many manufacturers require customers to pay for coverage up front, but third-party warranties offer flexible monthly payment plans.

If you’re interested in extended warranty providers, we recommend reading our reviews of top providers Endurance and CARCHEX to see which company offers the best coverage for your Buick. It’s a good idea to get free quotes from multiple providers and compare plans to find the right extended warranty for you.

How We Rate Warranty Providers

Our review process aims to deliver consistent and unbiased assessments of extended auto warranty providers. While there are multiple qualities that make a warranty company successful, our review team focuses on those we believe are the most important for consumers:

  • Reputation: It’s important that an extended car warranty company is able to meet its claims obligations. Companies with a strong rating from the Better Business Bureau (BBB) and a long history of reliable service score well in this category. We also evaluate the availability and transparency of each company’s contracts, as well as whether each provider offers a money-back guarantee.
  • Coverage: Our team of experts looks at the number of extended warranty plans available, as well as term limits, exclusions, and added benefits like roadside assistance. Ratings also take into account the availability of maintenance coverage.
  • Cost: Cost can be difficult to compare between providers because so many factors impact vehicle service contract pricing. To determine our cost score, we perform a secret shopper analysis for a variety of vehicles and plans and consider available deductibles.
  • Customer Experience: We listen to real customer sales calls and comb through reviews on sites like the BBB to learn about customer experiences. Warranty companies with a low volume of complaints score well in this area. We also consider the availability of mobile apps and chat features.
