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 protection plan from an extended warranty company.

CARCHEX offers five levels of extended protection for Buick vehicles and includes roadside assistance, trip protection, and more.

Buick Warranties for New Vehicles

When it comes to Buick warranties, your coverage depends on the model year of your vehicle. 2018, 2019, and 2020 Buicks all have different coverages, which begin on the original in-service date.

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. This warranty may also include pro-rated tire coverage through GM. 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 creates a hole, Buick will cover the repair costs.
  • eAssist: This service includes eAssist battery, eAssist battery disconnect, PowerPack assembly, starter generator unit, and more.

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 warranty protection. 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 for reliability, or above average. In 2019, J.D. Power ranked Buick as the fifth most dependable among 31 brands, with the Buick Verano as the most dependable compact car. 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 extended warranty, 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:

VehicleReplacementCost
2005 Buick CenturySpark plug replacement$184–$216
2017 Buick RegalWater pump replacement$538–$972
2015 Buick LaCrosseAlternator replacement$432–$1,084
2012 Buick EnclaveHead gasket replacement$1,511–$2,499

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 an extended warranty and make sure you’re protected should your systems or parts fail or break.

Buick’s Extended Limited Warranty

The manufacturer also offers ways to extend your Buick warranty protection. One way is to purchase an Extended Limited Warranty, which is what it sounds like: an extension of your limited warranty.

  • For 2018-2019 Buick vehicles, you can extend your coverage to up to six years or 70,000 miles.
  • For 2020 Buick vehicles, you can extend your coverage for up to five years or 60,000 miles.

Buick Extended Limited Warranties can be purchased through a Buick dealer. Though it’s great to have protection, here are some downsides to buying this extended warranty through the manufacturer:

  • You have to decide whether to buy the Extended Limited Warranty when you purchase your new Buick. That doesn’t give you much time to compare plans, prices, or other providers. You can buy a CARCHEX extended warranty at almost any point in the car’s lifetime.
  • Vehicles sold in California, Florida, Hawaii, Maine, and Minnesota aren’t eligible for Buick Extended Limited Warranties.
  • Repairs must be made at an authorized Buick dealer. This can cause a real inconvenience if you’re not near a dealership.
  • The contracts overlaps with your original Buick warranty, so you’re only covered for a few more years. CARCHEX contracts can be as long as 10 years.

Buick Protection Plan

Buick also offers a more traditional vehicle service contract called the Buick Platinum Protection Plan. There’s also a Silver coverage level, which is less comprehensive.

These plans have some of the same downsides as the Extended Limited Warranty, in that you’re tied to Buick dealerships, repair parts, and prices. Also, you don’t have nearly as many coverage options as you do with CARCHEX. There’s only two coverage levels, and the longest terms you can get are 60 months/60,000 miles. Buick Platinum Protection Plans will only cover cars up to 80,000 miles. CARCHEX covers vehicles well past 100,000 miles.
