Buick Extended Warranty: Who Owes the Repair and When It Starts

Buick’s extended warranty is a vehicle service contract sold as the Buick Protection Plan, in Powertrain, Silver and Platinum levels, through Buick dealers and on the plan’s customer site, mybuickprotection.com. It isn’t the factory warranty: it is a separate purchase with its own contract, obligor and refund rules. This page reads Buick’s own documents, all on 1 October 2026: the buick.com plan pages, FAQ and footnotes, the May 2023 sample contract buick.com links, the January 2026 brochure, the 2026 and 2025 Buick warranty booklets, an April 2026 edition of the contract from the customer site, and two older documents buick.com still serves.

Who owes you the repair: GM Protections, LLC, and Safe-Guard

Buick sells the plan on its own name. The plan page is headed “The only Protection Plan backed by Buick”, and the FAQ calls it “the only coverage endorsed by Buick and backed by General Motors.” The contract names a different company.

The sample contract buick.com links, form BUVSC 5/23, runs to 16 pages, every one stamped SAMPLE. It puts the obligations on GM Protections, LLC, the service contract provider or obligor: the company bound to pay your claim. The administrator, which takes the claim call and authorizes repairs, is Safe-Guard Products International, LLC, or Safe-Guard Warranty Corporation in Florida. buick.com’s footnotes and the January 2026 brochure name the same companies. Neither Buick contract says how GM Protections, LLC relates to General Motors; in the May 2023 sample, “GM” appears only inside the obligor’s name.

California is different, and the documents disagree about how. The May 2023 sample keeps GM Protections, LLC as the obligor there, with its California licence number printed as “[TBD]”. buick.com’s two footnotes and the April 2026 contract name Safe-Guard Products International, LLC; the brochure doesn’t mention California. In Massachusetts the obligor is the selling dealer.

Whether an insurer stands behind the obligor depends on where you live. In 27 jurisdictions, 26 states plus the District of Columbia, the obligations are fully insured by a reimbursement policy from Virginia Surety Company, Inc., and you can claim from it directly if a covered claim or refund goes unpaid for 60 days (30 in Alaska). The list includes California, Illinois, New York and Texas, but not Florida, Georgia, Michigan or Ohio. Elsewhere the obligations rest on the obligor’s full faith and credit alone. Our guide to who actually owes you the repair explains why that matters. The contract also says it is “not an insurance policy, a warranty, or a guarantee”, and that buying it is optional and can’t be a condition of credit.

The Buick contract is the GMC and Cadillac contract, in two editions

We compared the Buick sample sentence by sentence with the GMC sample our GM extended warranty guide reads and the Cadillac sample our Cadillac guide reads, all dated May 2023. Apart from 12 passages they are the same document, and in each of those the only change is the brand name or form code (8 changes), the administrator’s telephone number (7) or the web address of the electronic copy (1). The plan lists, exclusions, benefit caps, refund rules, state amendments and insured-state list are identical. The one Buick-specific sentence: “Under this Agreement, the Covered Vehicle must be a Buick.” So the GM guide’s clause-by-clause reading holds for a Buick plan on the May 2023 form.

A newer edition exists. mybuickprotection.com, where buick.com’s FAQ sends existing customers, links its “Customer Agreement” to a 17-page Buick Protection Plan contract, form GMPVSC 4/26. It matches Cadillac’s April 2026 edition apart from the brand name in the title (2 changes) and telephone numbers (11). Against the May 2023 sample, it names Safe-Guard Products International, LLC as the California obligor. It defines a breakdown as a failure in normal service, “provided the Covered Vehicle and/or Covered Part has received all scheduled maintenance”, dropping the wording that counts “normal wear and tear”. It excludes batteries under Platinum, 12V, hybrid electric and fully electric ones included, where the May 2023 sample excepted hybrid and electric batteries. It lets you use “Your preferred GM dealership” if you can’t return to the seller, won’t pay for damage from driving on after a warning light, excludes salvage, rebuilt and branded titles other than a GM buyback, and pays refunds within 30 days, with the 30-day full refund available “even in the event of a total loss.”

Rental, roadside, the transfer fee, the default deductible and the insured-state list don’t change. Our Cadillac guide sets the two editions side by side. The form number is printed at the top of the registration page, so check which one you are signing.

Powertrain, Silver and Platinum: what each level covers

The contract defines the levels in two different ways. Powertrain covers only the parts its list names, in four groups: the engine; the transmission, transaxle and transfer case; the drive axle; and hybrid and electric components. Silver adds front and rear suspension, climate control, electrical, steering and brakes. Both lists end with the same rule: a part not listed isn’t covered, “regardless of whether the damage to the non-covered part is caused by a Covered Part.” Platinum covers “ANY OTHER MECHANICAL BREAKDOWN” except its exclusions, and if a covered part damages an uncovered one, that repair is covered too.

The plan page adds audio, navigation, parking assist, the video display screen and adaptive cruise control under Platinum, and says the plan covers up to 1,500 parts depending on the level. That is the company’s count; the contract doesn’t number its parts. The January 2026 brochure blurs the upper levels: it says “Platinum and Silver coverage includes all mechanical parts of your vehicle” unless listed as not covered, while its own footnote and both contracts say Silver covers only the parts listed. The customer site’s comparison table marks “All mechanical parts (with some exclusions)” for Platinum only. The brochure’s parts page also gives the Fuel Systems group only the Platinum icon, though the contract’s Powertrain list names the fuel pump. Read the contract’s lists, not the brochure’s.

The clearest test of the levels is what Buick’s own powertrain warranty leaves out. The 2026 booklet excludes from gasoline engine coverage the sensors, wiring, connectors, engine radiator, coolant hoses, heater core, starter motor and the entire pressurized fuel system, in-tank fuel pump included, plus transmission cooling lines and hoses and all wheel bearings. Matched against the contract’s lists:

• From Powertrain up: the fuel pump, the transmission oil cooler and cooler hose, and wheel bearings.
• From Silver up: the starter motor, the heater core and named sensors such as oxygen, mass air flow and camshaft position.
• Platinum only: the engine radiator and wiring, which no list names and Platinum doesn’t exclude.
• No level: radiator and heater hoses, which Platinum excludes by name.

Of these 9 gaps, Powertrain closes 3, Silver 6 and Platinum 8. The matching is ours, and the count is the same as on our Cadillac guide. On a Buick, Silver against Platinum comes down to the radiator, the wiring and the electronics.

When the clock starts, and what a plan adds to a new Buick

The registration page has a box for Wrap. Without it, the plan starts on the purchase date at that day’s odometer reading and ends when the months listed pass or the miles listed are added, whichever comes first. With it, bought the same day as the car, the plan starts at the in-service date “and at zero (0) miles on the odometer”. Either way you sign that the term “includes any periods of applicable manufacturer’s warranties” and that parts still under factory warranty “are NOT covered by this Agreement until the expiration” of that warranty. The years overlap. They don’t add.

Buick’s own summaries leave Wrap out. The FAQ says the term “begins on your contract purchase date and mileage”, and the customer site that “Plan expiration is measured in time/miles from the purchase date and current odometer reading.” No Buick document we read prints the terms sold with Wrap, so ask the dealer to print the plan’s end date and mileage on the quote.

On a new Buick, the 2026 booklet covers the whole car for 3 years or 36,000 miles and the powertrain for 5 years or 60,000 miles. The plan page prints Silver and Platinum terms of up to 96 months or 100,000 miles, and Powertrain terms of up to 96 months or 120,000 miles. Bought at delivery, a Silver or Platinum plan at that maximum ends up to 36 months or 40,000 miles past the factory powertrain warranty’s end points, and up to 60 months or 64,000 miles past bumper-to-bumper’s. A Powertrain plan at its maximum ends up to 36 months or 60,000 miles past the powertrain warranty. Those are our subtractions, and they are end points, not what every car gets: a Buick driven hard reaches the mileage limit long before 96 months, and one driven little reaches 96 months first.

Those factory end points are the same as on the 2025 Chevrolet booklet our GM guide reads, and shorter than a 2026 Cadillac’s 4 years or 50,000 miles and 6 years or 70,000 miles. So a plan of the same length reaches further past a Buick’s factory warranty than past a Cadillac’s.

How late you can buy is printed three ways. The FAQ says after the sale only while the car is within its factory warranty “by at least 1,000 miles or 30 days prior to expiration”. The overview page says “at any time up to 8 years or 100,000 miles”. The contract expects later sales: bought after the factory warranty has ended, a plan covers nothing for the first 30 days or 1,000 miles, and the same is added to its end. If your Buick is out of warranty, get the eligibility rule in writing.

What a new Buick already carries: the 2026 booklet

The terms below come from the 2026 Buick Limited Warranty booklet, the newest Buick booklet in GM’s manuals index on the read date. We compared 9 of its terms with the 2025 booklet, and none changed.

Some items get less. Brake pads, filters, fluids, alignment and tire rotation are covered for only 7,500 miles, and remote key batteries and defect-caused windshield cracks for 12 months. Defective tires are replaced in full to 12,000 miles, then at a falling share of the price, down to 20% between 30,001 and 36,000 miles, and nothing after. Roadside assistance lasts as long as powertrain coverage, but the booklet says it isn’t part of the warranty and GM can end it.

The warranty passes to later owners. It is void on any vehicle ever titled salvaged, scrapped, junked or a total loss, and on a rebuilt write-off, so a salvage or rebuilt title ends it whatever the odometer says. Parts, calibrations or software not issued through GM void cover for what they damage, and damage from not installing an over-the-air update within 45 days isn’t covered. Buick dealers may help case by case after the warranty expires, and Buick sometimes runs special coverage adjustment programs, so ask a dealer to check your VIN before paying for a repair. What the booklet won’t pay is the inconvenience: it lists vehicle rental expenses among the incidental damages Buick won’t cover. That is where a plan’s extra benefits come in.

Deductible, benefit caps and what the plan will pay

buick.com prints no deductible, only “Choose the term and deductible that work for you.” The contract supplies the rules. If none is listed on the registration page the deductible is $0, and it applies per repair visit. A disappearing deductible is waived when you return to the selling dealer, which you can ask to change if you move more than 100 miles. Any deductible is waived when a part already repaired under the plan fails again.

The extra benefits have printed caps, the same in both editions:

• Rental car: up to $40 a day for up to 10 days, with prior authorization, for downtime repairs only. That is up to $400 per repair, our multiplication.
• Roadside assistance: up to $100 per occurrence in the United States and Canada, for towing, a jump start, a spare-tire change, lockout help and fluid delivery, plus up to 3 gallons of fuel up to three times a calendar year.
• Trip interruption: up to $200 a day for up to five days, $1,000 in all, when a breakdown 100 miles or more from home is held overnight because parts aren’t available. Expenses must fall within 72 hours and receipts arrive within 60 days.

Buick’s documents describe trip interruption three ways. The contracts exclude New York residents; buick.com’s footnote says “Not available to residents of CA and NY.” The plan page drops the contract’s condition that the delay be caused by unavailable parts. And the customer site’s claims page says receipts “must be submitted within 30 days of the vehicle’s breakdown”, where the contract allows 60. Send them early and you meet both.

Payments are capped at the manufacturer’s suggested retail price for parts and labor in a guide such as Mitchell or Alldata, at the car’s actual cash value for any one repair visit, and at what you paid for the car over the whole term. Diagnosis isn’t paid if the failure turns out not to be covered. If another warranty or recall covers the breakdown for less, the obligor pays the difference.

The repair costs on buick.com are also Chevrolet’s and Cadillac’s

buick.com sells the plan with a panel of average repair costs, from $10,747 for an engine down to $464 for a window motor. Its footnote credits them to the administrator’s claims “for Buick vehicles during the period of October 2022 to July 2024”. cadillac.com and chevrolet.com print the same 11 figures, to the dollar, and each footnote credits them to its own brand’s vehicles over the same period. gmc.com, with the same footnote worded for GMC, differs on all 11, starting at $10,149 for an engine. Three brands’ claims averaging out identically across eleven repairs would be a remarkable coincidence. It looks more like one set of figures reused on three sites, though nothing says whose claims they describe. That reading is ours.

Buick’s customer site prints its own list, credited to Safe-Guard Products International and the same Buick claims and period. It has no engine or brake caliper figure, and its other nine differ from buick.com’s.

The customer site is higher on 3 repairs and lower on 6. Rack and pinion steering is 20.9% higher than on buick.com, and the fuel pump 18.2% lower. Treat both lists as the administrator’s sales figures, which nobody outside can check, and price a real repair with our guides to transmission repair cost, starter replacement cost and fuel pump replacement cost.

What no level covers, and the wear-item plan sold separately

Platinum’s May 2023 exclusion list is mostly wear and body parts: the clutch, glass, lenses, body panels and trim, tires, wheels and alignment, batteries other than hybrid and electric ones, wiper blades, brake pads and rotors, lights, fuses and bulbs, filters and fluids, upholstery, paint, heater and radiator hoses, the exhaust system and the catalytic converter. Every level also excludes maintenance, pre-existing conditions, damage from overheating, sludge or water ingestion, a covered part ruined by an uncovered one, any hose or belt not listed, branded vehicles and commercial use unless the option is bought. Fully electric vehicles aren’t eligible at all.

The January 2026 brochure prints a longer list, with 12 items the May 2023 contract doesn’t name, among them spark plugs, headlamps, LEDs, brake drums and non-factory equipment. It also excludes batteries “Including 12-volt and hybrid batteries”, the reverse of the May 2023 contract, and the April 2026 contract sides with the brochure.

Buick sells wear items as a separate product. Buick Advanced Protection covers headlamps (not impact damage), fuses and bulbs, one wheel alignment, one set of wiper blades, one 12-volt battery, one set of front and rear brake pads and most major engine belts and hoses, for up to 6 years or 72,000 miles with no deductible. It is sold only on a car no more than 12 months from its in-service date and under 12,000 miles. Optional rotor cover pays up to $1,000 a set, and Advanced Protection Plus adds mechanical cover on up to 1,500 parts. The obligor and administrator are the same companies.

Older Buick plans: AMT Warranty Corp. contracts that started later

buick.com still serves two older documents that no current page links: a 2016 Buick Protection Plan brochure, form EW-BR-0091-16, and a sample vehicle service contract, revision REV0618, filed as “buick-protection plan-direct-contract-2020”. They describe a different product from a different company, and a used Buick may still carry one.

The brochure says coverage “is provided and administered by AMT Warranty Corp.”, with Wesco Insurance Company in Florida, and that both “are GM-approved providers but are not related entities of GM or its dealerships.” The sample contract makes AMT Warranty Corp. the obligor, insured by a Wesco Insurance Company policy, in two levels, Silver and Platinum. The biggest difference is the start date. On a car with factory warranty left, AMT coverage “begins upon the manufacturer’s warranty expiration of time or miles”, and the remaining factory warranty “will not reduce the actual time/mileage during which You have Coverage.” Today’s contract does the opposite.

The brochure’s benefit figures are the ones the 2017 GMC brochure prints, which our GM guide compares with the current contract. Its average replacement costs, such as $5,761 for an engine, were worked out from a labor guide at a $100 standard labor rate for GM models from 2013 on, not from claims. If a used Buick comes with a plan, ask for the contract itself: the obligor line, not the word Buick on the cover, tells you who pays and when coverage starts.

Claims, transfers and cancellation

Authorization from the administrator is required before any repair, and the obligor can inspect the car first. A claim must be submitted within 30 days of authorization, and after an out-of-hours emergency repair the paperwork is due within 30 days of the breakdown. Keep the replaced parts until the claim is settled, follow the owner’s manual maintenance schedule and keep the original receipts. Failing to meet these duties “may result in the denial of Your claim.”

Where to take the car is printed four ways. The May 2023 contract says the selling dealer if possible, otherwise call the administrator. The April 2026 edition allows “Your preferred GM dealership”. The FAQ says “any GM Dealer or authorized service provider”, and buick.com’s claim page says the claims team will help you find a participating General Motors dealership. Call before any work starts.

The plan transfers only in a private sale or a lease takeover, for a $50 fee ($40 in Florida) requested within 30 days. It can’t pass through a dealer or a trade-in, so at trade-in, cancel it for a refund. You can cancel at any time in writing:

• Within 30 days, no claim paid: a full refund, or within 60 days in California and Florida (Florida deducts any claims paid).
• Later, or after a claim: pro rata by whichever of time or mileage has run further, less claims paid and a $50 processing fee. In California the fee is $25 or 10% of the price, whichever is less.
• If financed: the refund goes to the lender unless the loan is paid off.

buick.com says the full refund applies “if no claims have been filed”, but the contract says paid. The April 2026 edition and the customer site both say refunds are paid within 30 days, and the customer site warns you may not be able to re-enroll after cancelling. See our guides to cancelling a plan and how cancellations go wrong.

Disputes: arbitration in the plan, BBB AUTO LINE for the warranty

The contract sends disputes to impartial arbitration: you propose at least three arbitrators, the administrator picks one, and the cost is shared equally unless the arbitrator directs otherwise. State pages change that in 20 states: Georgia, Mississippi, Nebraska and Wisconsin delete it, Vermont makes it voluntary, and 15 others, California and Florida among them, amend or replace it.

The 2026 Buick warranty booklet contains no arbitration clause. Its route is BBB AUTO LINE: free, available in all 50 states and the District of Columbia, generally hearing a case within 40 days, and a decision you can reject. The booklet does bar class and representative claims.

A Buick Protection Plan, a third-party contract, or neither

Whether any service contract is worth buying is covered in our guide to whether an extended warranty is worth it. On a Buick, three questions narrow it. First, what you already have: 3 years or 36,000 miles bumper to bumper and 5 years or 60,000 miles on the powertrain, which every plan’s term runs through, so price a plan by what it covers after those points. Second, the level, which decides who pays for the radiator, wiring and electronics. Third, who backs it: GM Protections, LLC (Safe-Guard in California on current documents), with an insurer behind it in 26 states and DC. A third-party contract names its own obligor, and a state register shows how to check it.

No Buick page, brochure or contract prints a price. The customer site prices plans only after you enter a VIN, the mileage and your state; we didn’t run a quote. Why there is no sticker price and where the markup comes from explain how the number is set and why it is negotiable. If you finance with GM’s lender, our GM guide reads its CFPB complaint file, and for an older car some insurers sell mechanical breakdown insurance.

Calls saying your Buick warranty is about to expire are a separate matter. In 2022 the FTC sued American Vehicle Protection Corp., a Florida seller it alleged had falsely claimed to be, or to be associated with, consumers’ carmakers or dealers, and had promised bumper-to-bumper or full coverage that was much more limited than represented. A stipulated order in March 2023 and a further order that July banned defendants from selling extended auto warranties and from outbound telemarketing. In 2024 the FTC sent more than $449,000 in refunds to consumers. See what regulators have done.

Common questions

How much does the Buick extended warranty cost?

Buick doesn’t publish a price, and the sample contract leaves it blank. It varies with the car, level, term and deductible and is negotiable; our guide to extended car warranty cost explains what moves it.

Is the Buick Protection Plan backed by GM?

Buick’s FAQ says it is “backed by General Motors.” The contract makes GM Protections, LLC the obligor, with Safe-Guard Products International, LLC as administrator, and doesn’t say how GM Protections relates to General Motors. In 26 states and DC, Virginia Surety Company, Inc. insures the obligor’s obligations.

What is the difference between Buick Silver and Platinum coverage?

Silver covers only the parts its list names. Platinum covers any mechanical breakdown except its exclusions, including damage a covered part causes to an uncovered one. Of the parts Buick’s powertrain warranty leaves out, the radiator and wiring are Platinum only.

Can I buy a Buick extended warranty after I bought the car?

The FAQ says yes while at least 1,000 miles or 30 days of factory warranty remain. The overview page says any time up to 8 years or 100,000 miles, and the contract adds a 30-day or 1,000-mile waiting period if you buy after the factory warranty has ended. Get the rule in writing.

Is the Buick Protection Plan transferable?

Yes, in a private sale or lease takeover, for $50 ($40 in Florida) within 30 days, but not through a dealer or trade-in.

How long is the Buick factory warranty, and does it transfer?

On a 2026 Buick it runs 3 years or 36,000 miles bumper to bumper and 5 years or 60,000 miles on the powertrain, whichever comes first, from the day the car was first delivered or put in use. It passes to later owners for the rest of its term, unless the car has been titled salvage, junk or a total loss.
