Do you know the difference between a Buick Extended Limited Warranty and a Buick Protection Plan? Understanding the key differences between these two coverage options can help you decide which Buick extended warranty is worth the investment.

In this review, we look at Buick extended warranty options, including coverage, term lengths, and exclusions. We also reviewed some of the best extended car warranty providers you can consider if Buick’s extended warranty products don’t fit your needs.

The Gist:

  • Buick offers an extended bumper-to-bumper vehicle warranty and three levels of extended protection plans: Powertrain, Silver, and Platinum. 
  • Our review found Buicks have lower than average annual repair costs but a higher likelihood of a severe repair.
  • To extend coverage for your Buick, you may be able to save money and find more flexible extended warranty plans from a third-party company.

Buick Extended Warranty Coverage

Buick offers two types of extended warranty options: the Buick Extended Limited Warranty and the Buick Protection Plan. The Extended Limited Warranty lengthens the manufacturer’s standard bumper-to-bumper coverage that comes with 2020 or newer Buick vehicles from 3 years/36,000 miles to 5 years/60,000 miles. The Protection Plans offer several term limits up to 5 years/60,000 miles with three tiers of coverage.

There are a few differences to note with these Buick extended warranty programs. To give you a better understanding of Buick’s extended warranty options, we’ve compared them below.

Buick Extended Limited Warranty

The Buick Extended Limited Warranty protects parts such as the infotainment system and high-tech features, as well as the electrical system and powertrain.

The Buick Extended Limited Warranty cannot be canceled and must be purchased when you buy your new vehicle. While this may be limiting for some Buick drivers, the warranty does offer vehicle-specific protection and peace of mind.

Other benefits with a Buick Extended Limited Warranty include:

  • No deductible
  • Fully transferable
  • Backed by General Motors
  • Uses genuine Buick parts

Buick Protection Plans

Buick’s Powertrain, Platinum, and Silver Protection Plans are alternatives for extended auto warranty coverage. Be aware that these vehicle service contracts are provided by AMT Warranty rather than General Motors. The coverage plans can be purchased at any time, as long as the vehicle has fewer than 80,000 miles on the odometer.

Here’s how the three tiers of Buick’s Protection Plans compare:

Each plan offers comprehensive protection, but the Buick Platinum Plan covers far more accessories and parts. Still, Buick Protection Plans only cover repairs due to defective materials or workmanship.

Some exclusions include:

  • Battery and battery cable/harness
  • Lenses, sealed beams, and light bulbs
  • Tires and wheels/rims
  • Maintenance services
  • Key fobs and tire pressure sensors
  • Brake rotors and drums
  • All exhaust components
  • Trim items

Buick’s Protection Plans also include a few additional perks, such as:

  • Locksmith services: Up to $35 reimbursement if your keys are lost, broken, or locked in your vehicle
  • Rental car reimbursement: Up to $40 per day with a maximum benefit of $280 per occurrence
  • Towing and roadside assistance: Up to $150 per occurrence
  • Trip interruption benefits: Up to $200 per day if a covered breakdown happens more than 100 miles from your home and the repair shop keeps your vehicle overnight (maximum $800 per trip)

Buick Protection Plans may be canceled any time. If you cancel within 60 days of purchase and did not file any claims, you’ll receive a full refund. If you cancel after the 60-day grace period or after filing a claim, you’ll receive a prorated refund. Buick Protection Plans can also be transferred to any individual owner for a $75 fee.

Other Buick Vehicle Protection Plans

Buick offers other plans that could save you money on car repairs and maintenance. These optional plans are not considered extended warranties:

  • GAP Coverage: Covers the “gap” between an auto loan balance and the value of your vehicle paid by insurance in a total-loss scenario
  • Pre-Paid Maintenance: Follows your vehicle’s service schedule and avoids maintenance cost inflation
  • Appearance Guard: Covers minor dents and upholstery damage, plus key or key fob replacement and windshield repairs
  • Tire and Wheel Protection: Offers one level of coverage for tire repair or replacement, a second level that adds wheel damage coverage and roadside assistance, and a third level that adds minor repairs for cosmetic wheel damage
  • XS Wear® Lease Protection: Covers cosmetic damages and some charges for excess wear and tear for leased Buicks
  • Advanced Lease Protection: Provides additional coverage for leased Buicks during the factory warranty period as well as coverage after the factory warranty expires

Buick Vehicle Service Contract Cost

Drivers can use Buick’s Platinum Protection Plan online shopping tool to see how much they’d pay for a vehicle service contract from the manufacturer. Here are sample quotes we received for a 2015 Buick Enclave with 60,001 to 80,000 miles and no time left on the original manufacturer warranty:

Buick
Platinum
Protection Plan
Pay-in-Full PriceMonthly Price
2 years/24,000 miles$2,621.05$190 for 14 months
3 years/36,000 miles$3,484.60$169.95 for 21 months
4 years/48,000 miles$4,260.75$208.85 for 21 months
5 years/60,000 miles$5,114.80$251.66 for 21 months

For the quotes above, paying in full gets you a five percent discount, and paying in monthly installments requires a down payment of about $99.


Do You Need Buick Extended Warranty Coverage?

To decide if you would benefit from Buick extended warranty coverage, we recommend looking into Buick reliability to see if you’d feel comfortable paying commonly reported repair costs. You may also want to consider how long you will own your Buick. Drivers who will likely sell their cars before the manufacturer’s warranty expires have little need for an additional coverage plan.

To assess Buick’s reliability, our research team turns to RepairPal, a cost-estimation service for car repairs. In RepairPal’s 2021 Reliability Ratings, Buick earned a 3.5 out of 5, placing its reliability above average. This rating is based on three factors: average annual repair cost, frequency of repairs, and the likelihood of a severe repair.

See how RepairPal assessed Buick’s reliability compared to the average across 32 car brands:

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

Buick has a lower than average annual repair cost and frequency of repairs, but a higher likelihood of a severe repair. RepairPal considers a severe repair to be one that costs at least three times the average annual repair cost for all models. Based on this data, it may not be worth it for Buick drivers to invest in extended auto warranties, especially for those who feel comfortable paying for repairs out of pocket.

However, mechanical breakdowns can happen with any vehicle, and extended warranty coverage gives you peace of mind on the road. If the manufacturer’s extended warranty isn’t the right fit, you may want to consider other reputable extended car warranty companies.

Buick Limited Warranty

A new Buick vehicle that you buy or lease comes with the following manufacturer warranties:

Buick
Model Year
Buick
Factory Warranty
Term Length
2020 or newerBumper-to-Bumper Limited Warranty3 years/36,000 miles
Powertrain Limited Warranty5 years/60,000 miles

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

Buick’s powertrain warranty handles covered repairs needed due to defective parts or labor for important components such as the engine, transmission, and driveaxle. The manufacturer’s warranty also include 24-hour roadside assistance and alternate transportation or reimbursement of certain transportation costs during covered repairs.

Buick’s factory warranty doesn’t cover normal maintenance, and it doesn’t apply to damage caused by accidents, the environment, insufficient maintenance, or misuse or alteration of the vehicle. The manufacturer requires covered repairs to be done at a Buick, Cadillac, Chevrolet, or GMC dealership unless a dealership or part isn’t reasonably available.

If you buy a Certified Pre-Owned (CPO) Buick, you’ll get a 6-year/100,000-mile powertrain limited warranty with roadside assistance, which starts from the vehicle’s original mileage and in-service date, along with a 1-year/12,000-mile bumper-to-bumper limited warranty, which starts on your purchase date.


Third-Party Extended Warranty Benefits

Third-party providers can offer several benefits not commonly found in a manufacturer’s extended warranty or vehicle service contract, including:

  • A higher number of repair facility options
  • Additional coverage tiers 
  • More affordable payment plans
  • Flexible opt-in date for older cars

Buick Extended Warranty: Our Take

A Buick Extended Limited Warranty may be a smart investment for Buick drivers who want to drive off the lot with additional new car warranty protection. A Buick Protection Plan is a good fit for drivers looking for more traditional warranty protection that combines bumper-to-bumper and powertrain coverage.

A third-party Buick extended warranty is a good option for drivers who want:

  • Flexible options when choosing a repair shop
  • More comprehensive coverage
  • More payment plan options

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.
