Find out how Buick’s extended warranty measures up to third-party providers.


Buick offers two extended warranty plans, but has seven other protection plans that you can add on top. While Buick's extended warranty plans can cover everything from major car repairs to minor fabric tears, they may not be worth the cost in comparison to third-party providers.

Third-party extended warranty companies provide an alternative to buying plans directly from the dealership. We’ve done our research on the best extended car warranty providers. Through our analysis, we have determined that Endurance is the Best Overall option for extended auto warranties, and a few other leading brands trail just behind.

Why You Might Need A Buick Extended Warranty

No car is immune to breakdowns. Here are some of the most common problems for Buicks that can cause expenses for car owners, according to RepairPal:





Failure of air compressor for rear air springs



Fuel level sensor failure



Engine oil or coolant leak


Park Avenue

Failure of mode and temperature door actuators



Key stuck in ignition lock cylinder


Buick has also changed its limited warranty for 2020 models. In 2019, new Buicks had bumper-to-bumper coverage for 4 years/50,000 miles and powertrain coverage for 6 years/70,000 miles. This year, new car coverage has been reduced to 3 years/36,000 miles for bumper-to-bumper and 5 years/60,000 miles for powertrain. This means that car owners will have to consider an extended warranty sooner, since Buick's factory warranty coverage won’t last as long.



Overview Of Buick’s Extended Warranties

Buick offers two extended warranty plans, one called the Silver Coverage, which protects 11 components of your car, and one called the Platinum Protection Plan, which builds off the Silver Coverage. The starting cost for the Platinum Protection Plan is $1,319.

Platinum Protection Plan

The Buick Platinum Protection Plan, Buick’s primary extended warranty, has a $0 deductible with prices starting at $1,319 for 24 months/24,000 miles. Other term options are:

  • 36 months/36,000 miles
  • 48 months/48,000 miles
  • 60 months/60,000 miles

You can visit the website or call your dealer to get an accurate quote based on your Buick’s model, age, and other factors.

Silver Coverage

Buick also offers Silver Coverage, which covers fewer components than the Platinum Protection Plan. It still covers the majors systems, such as:

  • Engine
  • Transmission
  • Drive axle
  • Turbocharger/supercharger
  • Transfer case
  • Steering
  • Electrical
  • Airbags/safety restraint system
  • Brakes
  • Air conditioner
  • Seals and gaskets



Other Buick Protection Plans

In addition to the two extended warranties, Buick also has seven other protection plans, two of which are only available for leased cars. These plans cover everything from tire and wheel repairs to maintenance costs.



GAP Coverage Plan

The GAP Coverage Plan helps in the event your vehicle is considered a total loss. Most insurance companies will only compensate you for the current value of the vehicle, not for the deductible or what is still owed on the car. This plan can help fill that gap. 

Tire and Wheel Protection Plan

The Tire and Wheel Protection Plan provides tires and wheels protection against road hazards. It covers repairs and replacements of flat tires and damages wheels, along with minor repairs for cosmetic damage. There is a $0 deductible. 

Pre-Paid Maintenance Plan

The Pre-Paid Maintenance Plan helps cover regular maintenance costs, such as tire rotations and oil changes. This plan has no deductible. 

Appearance Guard Plan

The Appearance Guard Plan helps your vehicle look new for years by covering cosmetic damage, such as exterior dents and interior fabric rips. This plan has a $0 deductible. 

XS Wear® Lease Protection Plan

The XS Wear Lease Protection Plan provides coverage beyond the typical wear and tear. This plan is only available for leased Buicks and has a $0 deductible. 

Advanced Lease Protection Plan

The Advanced Lease Protection Plan provides additional services during the manufacturer’s warranty and extends that coverage after the manufacturer’s warranty expires. This plan is only available for leased cars, and there is a $0 deductible. 



Buick Extended Warranty Pros And Cons

Now that the plans are laid out, it’s time to decide if buying Buick’s extended warranty is worth it. Buick offers a wide variety of protection in its nine plans, covering everything from minor cosmetic damage to major breakdowns. Buying one of these also ensures that any repairs or replacements are handled directly between the dealership and auto manufacturer, meaning that the car owner doesn’t have to manage all of the paperwork. 

But Buick’s plans have some downfalls, too. While Buick’s deductible is competitive at $0, the plan prices make up for it. The starting price for the Platinum Protection Plan is $1,319 for the lowest amount of coverage (24 months/24,000 miles). That price could quickly increase if you extend the coverage or add one of the other protection plans on top. 

Even with the variety, there are still limitations in terms of what is covered and how much Buick is willing to reimburse for one occurrence or one part. In the end, a Buick plan may not be worth the cost.

Third-Party Providers For Vehicle Service Contracts

We recommend a third-party extended vehicle service contract over Buick’s extended warranty for a number of reasons. You can generally get a better price on a third-party extended warranty because you’re not locked in to only the dealership’s options. 

Third-party plans also provide coverage for longer. Endurance, for example, offers coverage for up to 200,000 miles, while Buick only covers up to 60,000 miles.

Lastly, third parties give you more coverage options. Endurance offers five tiers with several plans under each instead of Buick’s two levels.

We have done extensive research into the best third-party extended warranty options and have come up with three that stand out from the rest.

  • Endurance gets the first-place spot as Best Overall for its quality of coverage and customer service. Check below to see how Endurance compares to Buick.
  • Tied in second place is CarShield because of its month-to-month contract options and six levels of coverage and CARCHEX because of its outstanding company reputation and customer care.
