Quick answer

A car warranty is a promise to fix certain defects or malfunctions within a specified period, often limited by both time and mileage. A manufacturer's warranty comes with a new car's purchase price. Separately purchased coverage, commonly called an extended warranty, is usually a service contract that pays only for repairs its terms cover.

What does a car warranty actually cover?

A car warranty covers specified defects or failures, not every expense of owning a vehicle; the written terms determine which repairs are included.

The distinction is between coverage that comes with the car and coverage you buy separately. Under federal law, a separately purchased auto service contract isn’t a warranty, even if the seller calls it an “extended warranty.”

The Federal Trade Commission’s auto warranty guide explains that a service contract seller agrees to perform or pay for the repairs or services listed in the contract.

Coverage type How you get it What to check
Manufacturer’s warranty Included in the new vehicle’s purchase price Covered defects, time limits, and mileage limits
Warranty accompanying a used car May come with the vehicle Whether coverage exists and what its written terms promise
Separately purchased service contract Bought as an optional product Covered repairs, exclusions, deductibles, and claim requirements

Service contracts typically don’t cover accident damage or normal wear and tear. Routine maintenance, such as oil changes and tire replacement, is also typically excluded, although some contracts cover certain maintenance services.

That means “my car needs work” and “my contract covers this work” are different questions. A contract covering mechanical breakdowns may exclude a problem caused by normal wear.

Our car warranty guide covers the broader topic. For your own purchase, focus on the written coverage rather than the product’s name. Even “bumper-to-bumper” coverage can have limitations and exclusions.

How long is a factory warranty on a car?

A factory warranty lasts for the time or mileage specified by the manufacturer, usually ending when you reach whichever limit comes first.

The manufacturer’s warranty is included in the price of a new vehicle. It generally covers manufacturer defects or failures during the applicable coverage period.

Rather than assuming a standard duration, check the warranty that accompanies the car. You need to understand both its time limit and its mileage limit, since remaining time alone doesn’t establish that coverage is still available.

What happens when the factory warranty ends?

A separately purchased service contract may pay for some repairs after the manufacturer’s warranty expires. It may also cover certain problems outside the manufacturer’s coverage.

But buying a contract doesn’t necessarily mean you’re extending every part of the original warranty. The covered repairs and exclusions may be different.

Should you buy extra coverage before it expires?

Check for overlap first. The FTC says a service contract that starts before the manufacturer’s warranty expires probably won’t help if it duplicates coverage you already have.

Compare both the covered problems and the coverage periods. Don’t rely solely on a seller saying the extra contract offers “more protection.”

You may also be able to buy a service contract after purchasing the car, although eligibility restrictions can apply. You don’t need to treat the vehicle purchase as your only opportunity to consider optional coverage.

How does a warranty work on a used car?

A used car may have remaining manufacturer coverage, a warranty accompanying the sale, or an optional service contract, so verify each possibility separately.

Manufacturer coverage may still apply if the relevant time and mileage limits haven’t been reached. A used vehicle might also come with some other type of warranty coverage.

Those possibilities aren’t interchangeable. Ask what coverage comes with the car’s price and what the seller is offering for an additional charge.

Does a dealership purchase automatically mean coverage?

Don’t assume the word “dealership” tells you what warranty you’re getting. Ask for the coverage in writing before paying, and make sure it matches the seller’s description.

If you’re expecting a short warranty after purchase, have the seller identify the exact written promise. Verify what it covers, when it ends, and whether there are mileage limits. Questions about rights under your state’s law belong with your state consumer protection office or a qualified legal professional.

What about buying from a private seller?

For a private purchase, check whether any manufacturer coverage remains and whether an existing service contract can transfer to you.

Service contract transfer terms vary. The FTC recommends checking whether transfer is allowed and whether there’s a fee. An existing contract shouldn’t be treated as yours until you’ve verified those terms.

You may also be able to purchase separate coverage from an independent provider after buying the car. Eligibility restrictions can apply, so don’t assume a particular used vehicle qualifies.

Whether you buy privately or from a dealership, the useful question is the same: what written coverage will actually apply to this vehicle after the sale?

What does a used car warranty from a dealership cost?

Separately purchased used car coverage has no single price; the cost depends on the vehicle, covered repairs, contract length, and other contract terms.

The FTC’s undated guidance, accessed in September 2026, says auto service contract prices can range from several hundred dollars to several thousand. That’s a broad range, not a price estimate for your car.

What you’ll pay usually depends on:

  • Whether the vehicle is new or used.
  • Its make and model.
  • Which repairs or services the contract covers.
  • How long the contract lasts.

The purchase price isn’t necessarily your entire expense. You may also owe a deductible each time the vehicle is serviced or repaired. Some contracts use depreciation when calculating benefits, meaning they pay only part of repair or replacement costs based on mileage.

Coverage may also fall short of the full cost of towing or renting a car.

Can you negotiate the price?

The Consumer Financial Protection Bureau says the cost of an extended warranty can be negotiated when you purchase your vehicle. These products are optional and generally cannot be required to get an auto loan.

Before signing loan documents, ask whether they include charges for optional products. Don’t confuse a coverage offer with a financing requirement.

When reviewing extended car warranty options, compare covered repairs, exclusions, deductibles, duration, and any partial-payment provisions. A lower purchase price alone doesn’t establish better value, just as a higher price doesn’t establish broader protection.

How do repairs and claims work with a service contract?

The contract sets the repair process, including whether you need advance approval, who authorizes payment, and what maintenance requirements you must follow.

Start with the repair instructions in the contract before authorizing work. Find out whether the provider or another party must approve repairs or towing in advance.

Many service contracts sold by dealerships are handled by independent companies called administrators. The administrator makes decisions about authorizing claim payments, so the dealership selling the contract may not be the business deciding whether a repair is covered.

What should you check before a repair?

Ask the contract provider:

  • Does this repair require pre-approval?
  • Who makes the coverage decision?
  • Does the contract restrict where the car can be serviced?
  • What deductible or uncovered repair costs would you owe?
  • Are towing or rental expenses fully covered, partly covered, or excluded?

Few contracts cover all repairs and maintenance. Check whether the problem falls within a covered category and whether an exclusion changes the answer.

Do you have to use the dealership?

For a manufacturer’s warranty, you don’t have to use the dealership for routine maintenance or repairs to keep coverage in effect. The FTC says a dealer cannot deny warranty coverage simply because someone else performed that work.

Using aftermarket or recycled parts also doesn’t, by itself, end the warranty.

A separately purchased service contract needs its own review. It may restrict where work is performed and require you to follow the manufacturer’s routine maintenance recommendations. Failing to meet those maintenance requirements could end the contract’s coverage. Don’t assume the rules for a factory warranty and an optional contract are identical.

Are dealership or third-party warranties worth it?

A service contract may be worthwhile if its covered benefits justify the cost, but overlapping coverage, exclusions, and your ownership plans can reduce value.

The FTC cautions that you could pay more for a service contract than you receive in benefits. The CFPB also suggests considering whether setting aside money for maintenance or repairs would make more sense for your circumstances.

Judge the contract, not just the seller

Service contracts are sold by manufacturers, dealers, and independent companies. Buying through a dealership doesn’t necessarily mean the manufacturer is responsible for coverage.

Find out which company actually stands behind the contract and which company administers claims. The value of the coverage depends on the business responsible for honoring it. The FTC recommends checking with your state consumer protection office for complaints.

Be cautious about unsolicited warranty pitches. A caller or message may suggest a connection to your dealer or manufacturer that doesn’t exist.

Match the coverage to your ownership plans

Consider what repairs are covered, what’s excluded, how you’ll use the vehicle, and how long you expect to keep it.

If the contract would outlast your ownership, check whether you can transfer it, whether a transfer fee applies, or whether a shorter contract is available.

A useful comparison isn’t simply “coverage versus no coverage.” It’s the contract’s cost and likely usefulness versus the coverage you already have and the option of saving for repairs yourself.

Get the terms in writing before paying. If the sales explanation and contract don’t match, resolve that difference rather than assuming the spoken promise will apply.

What should you do before buying coverage?

Check your existing warranty, read the proposed contract, and compare its full cost with the repairs it would actually pay for before deciding.

Identify who authorizes claims, whether repairs need pre-approval, and what you’d still owe. Then check cancellation and transfer terms.

The car warranty plan comparison page is another place to review options, but the written contract remains the basis for your decision. If coverage details are unclear, ask for a written explanation before paying.

Frequently Asked Questions

Is an extended car warranty the same as a factory warranty?

No. A manufacturer’s warranty is included in the purchase price of a new vehicle. An extended warranty is generally a separately purchased service contract, which isn’t a warranty under federal law. It may cover different repairs or apply after factory coverage ends, but it can also duplicate protection you already have.

Can you cancel a vehicle service contract?

The Consumer Financial Protection Bureau says you have the right to cancel an extended warranty or vehicle service contract at any time and end coverage. Before buying, review the cancellation terms rather than assuming you’ll receive a full refund. Ask how any refund would be calculated and whether a cancellation fee applies.

Does a car warranty cover oil changes and worn tires?

Extended warranties and service contracts typically exclude routine maintenance, including oil changes and tire replacement. Some contracts do include specified maintenance services, so check the written terms. Normal wear and tear is also typically excluded. A contract covering mechanical breakdowns doesn’t necessarily cover a repair that’s needed because a part has worn out.
