An extended car warranty is protection from the vehicle manufacturer against mechanical breakdowns. This term is sometimes incorrectly used to describe coverage from third-party providers, which offer similar protection plans called vehicle service contracts. CARCHEX is a vehicle service contract provider.

Buick is a brand of General Motors (GM), which offers popular models like the Enclave, Envision, and LaCrosse. Whether you purchase a new, leased, or certified pre-owned Buick vehicle, you want to make sure you get coverage on your systems and parts.

A Buick warranty comes with all new cars. Below, we explore the different factory plans, as well as the benefits of purchasing a vehicle protection plan from a third-party provider. CARCHEX offers five vehicle service contract options for Buick vehicles and includes roadside assistance, trip protection, and more.

Buick Warranties for New Vehicles

Buick’s warranty has changed in recent years. In 2019, it was offering a 4-year/50,000-mile bumper-to-bumper warranty and 6-year/70,000-mile powertrain warranty. In 2020, it cut coverage to 3 years/36,000 miles and 5 years/60,000 miles for both coverage levels. If you bought a 2019 model year you still may have some of the longer powertrain warranty left, depending on your mileage.

What Do These Warranties Cover?

Each of these warranties protects different parts of your Buick.

  • Bumper-to-Bumper Limited Warranty: This covers all repairs, parts, and labor to correct defective materials or workmanship in your new vehicle using Genuine GM Parts. You can transfer the Buick bumper-to-bumper warranty to a new owner.
  • Corrosion Coverage: This protects you from paying for any corroded body and sheet metal components on your Buick.
  • Powertrain Limited Warranty: This warranty covers defective parts of the powertrain, including the engine (all internally lubricated parts, engine oil cooling hoses and lines, and more) and the transmission/transaxle (all internally lubricated parts, torque converter, case, seals and gaskets, and more).
  • Courtesy Transportation Program: Buick will reimburse certain expenses such as a rental car if your car needs covered repairs.
  • Roadside Assistance Program: If your car breaks down on the side of the road, you can contact roadside assistance for help. Buick offers this program through Allstate Roadside Services.
  • Rust-Through Coverage: If any of your sheet metals rust through and create a hole, Buick will cover the repair costs.

What’s Not Covered?

Like most warranties, Buick only covers mechanical breakdowns caused by errors on their end. That means if your car is damaged from any of these events, it’s not covered by Buick:

  • Accident
  • Misuse
  • Alteration
  • Lack of maintenance
  • Contaminated or poor-quality fuel
  • Chemical treatments or aftermarket products
  • Environmental impact (hail, salt, snow, etc.)

Buick warranties also don’t cover maintenance items or services, such as brake pad replacements or oil changes.

Is Buick’s Warranty Enough?

As you can see, Buick’s coverage gets shorter and shorter every year. Chances are, your Buick will outlast its factory warranty protection and you’ll want to get the most out of your car’s lifespan without paying hefty out-of-pocket costs. You can extend your car’s life and get unexpected repairs and replacements covered under a vehicle service plan from a third-party provider like CARCHEX.

Something else to consider is Buick’s reliability. According to RepairPal, Buicks are rated 3.5 out of 5.0 for reliability, or above average. In 2024, J.D. Power ranked Buick as the third most dependable car brand among 29 others, with the Buick Encore as the most dependable small SUV. Other models were mentioned as runners-up in other categories. Ultimately, this means your Buick will likely stick around for many years.

However, even the most reliable cars need repairs, especially as they age. As you consider purchasing a Buick vehicle service contract, you’ll want to know how much Buick repairs and replacements will cost. On average, Buicks costs $608 annually in repairs.

To break down what some of these expenses could be, here are some costs for common Buick problems:

Vehicle

Replacement

Cost

Encore

Drive belt tensioner

$268–$300

Encore

Turbocharger boost pressure solenoid

$483–$504

Enclave

AC compressor

$788–$975

Enclave

Tie rod replacement

$162–$176

Would you be in a bind if you had to pay for one of these repairs? If you want to have peace of mind and avoid hefty car expenses, you’ll want to purchase a vehicle service contract and make sure you’re protectedshould your systems or parts fail or break.
