Buicks are reliable vehicles, not often requiring expensive repairs. But is a Buick extended warranty a good idea in case your Buick does encounter a problem? This article explains everything you need to know about a Buick extended warranty. Our team will help you decide if you should purchase an extended warranty from Buick or a protection plan from a third-party provider.

The best way to determine the coverage you need is to compare plans from multiple sources. We’ve researched the best extended warranty companies in the industry and recommend getting free, personalized quotes from a few top-rated providers so you can compare coverage and costs side-by-side.

Buick Extended Warranty Overview

A Buick extended warranty can be purchased at the same time that you buy your new Buick. The extended warranty increases the coverage length for the bumper-to-bumper Buick warranty.

Buick Extended Warranty Coverage Term
2020 Buick Extended Warranty 5 years/60,000 miles
2018 to 2019 Buick Extended Warranty 6 years/70,000 miles
Premier Maintenance Plan 2 years/24,000 miles to 5 years/60,000 miles

With all Buick warranties, your new Buick must be serviced at a Buick dealership. Dealerships are good places to have your vehicle repaired because dealership technicians can specialize in and are likely better able to understand your vehicle’s particular needs. However, it can be inconvenient to take your car to a dealership depending on where your car breaks down.


All Buick extended warranties come with the following added benefits:

  • Courtesy transportation program: Reimbursement for alternative transportation while your damaged vehicle is undergoing repairs
  • Roadside assistance program: 24/7 roadside assistance provided by Allstate Roadside Services

Do You Need Extended Warranty Coverage?

According to RepairPal, the average annual maintenance cost for Buick vehicles is about $608 a year. The most common problems include:

  • Air compressor failure for rear air springs
  • Fuel level sensor failure

Reliability does depend on your model of Buick. The Buick Enclave has a RepairPal reliability rating of 3.0 out of 5.0 with an average annual repair cost of $720. It is more likely to require major repairs than other cars. Buick’s least expensive to maintain model is the Verano. It has a RepairPal reliability rating of 4.0 out of 5.0 and an average annual repair cost of $478.

You can estimate the potential value of any Buick extended warranty by understanding how much it would cost to pay for service costs yourself.

Buick Factory Warranty

All new and certified pre-owned (CPO) Buick vehicles come with a vehicle service contract. Depending on your Buick, your car may already be covered. Most manufacturer bumper-to-bumper warranties offer fairly comprehensive coverage, covering most every part of your vehicle. You can generally expect your Buick to last at least until the warranty period expires.

The term lengths for Buick warranties are outlined in the chart below:

2018 2019 2020 CPO
Bumper-to-Bumper Limited Warranty 4 years/
50,000 miles
4 years/
50,000 miles
3 years/

Designed to increase fuel efficiency in four-cylinder engines, eAssist is an engine system present in some Buicks. The eAssist coverage offered by Buick promises to pay for repairs for the eAssist components found in some 2018 Buicks.

Buick Extended Warranty Cost

The cost of any extended warranty will depend on your Buick’s year and model. Manufacturer extended warranties are offered by dealerships and subject to some negotiation.

In general, you can expect a Buick extended warranty to cost anywhere between $1,000 and $2,000. Manufacturer extended warranties tend to be more expensive than third-party alternatives, though not always. Speak with your Buick dealer to learn about cost options.

Benefits of a Third-Party Extended Warranty

If you want to extend the warranty on your Buick, an extended warranty from the manufacturer isn’t your only option. There are many third-party warranty providers that may offer extended coverage plans that better suit your needs.

While manufacturer extended warranties tend to be more comprehensive, they are also generally more expensive and do not usually offer coverage terms that extend very high. Third-party warranties offer additional coverage options and common benefits such as towing, trip interruption, and potentially even wheel protection.

The primary drawback of a Buick extended warranty is that it must be purchased when you buy your Buick. With a third-party provider, you can purchase coverage at any time. Additionally, a third-party provider offers more warranty plans or warranty options than Buick and the accessibility to use the repair shop of your choosing.

Oftentimes, when you buy an extended warranty with your vehicle, the cost of that warranty is rolled into your financing. This means you end up paying interest for your warranty, further increasing the cost.

Buick Extended Warranty: Our Verdict

The 2020 Buick extended warranty lasts for 5 years/60,000 miles. A Buick warranty can provide good coverage, but has some limitations.

Third-party warranties for Buicks are likely to be cheaper and offer a better range of coverage options. Most importantly, you can purchase such a warranty after you’ve owned your Buick for some time. By then, you may have a better idea of which components you think need extended warranty coverage and which do not.
