Note (September 2026): The original version of this article said factory warranties are limited to one year. That was wrong. Most new-vehicle warranties in the US run at least three years or 36,000 miles for bumper-to-bumper coverage and five years or 60,000 miles for the powertrain, and some run longer. The text below has been corrected.
An auto extended warranty is an optional vehicle service contract, sold by a manufacturer, dealer or independent company, that pays for specified mechanical or electrical repairs after the factory warranty ends. It is not a true warranty under federal law. As of September 2026, plans average about $139 a month according to Cars.com quotes, usually with a per-repair deductible, and they exclude routine maintenance and wear items.
Key Takeaways
- The Federal Trade Commission (FTC) calls extended warranties “auto service contracts”: optional, separately priced contracts that are not the same as the manufacturer’s warranty included in a new car’s price.
- Factory coverage is longer than one year: Ford, Toyota and Chevrolet publish 3-year/36,000-mile bumper-to-bumper and 5-year/60,000-mile powertrain terms; Hyundai goes to 10 years/100,000 miles on the powertrain.
- Cars.com quotes gathered in February 2026 averaged $139 a month, from about $117 for powertrain-only plans to $160 for bumper-to-bumper plans.
- A Consumer Reports survey of about 12,000 subscribers found that more than half never used their extended warranty, and the median repair saving ($837) was below the average price paid ($1,214).
- The FTC says robocalls about “your car’s extended warranty” are illegal and not from your dealer or manufacturer. Hang up and report them.
An auto extended warranty can provide peace of mind to the owner of a vehicle. Unlike a factory warranty, which in the US typically runs three years or 36,000 miles for bumper-to-bumper coverage and five years or 60,000 miles for the powertrain (longer at some brands, such as Hyundai’s 10-year/100,000-mile powertrain coverage), an extended warranty is a separate contract that adds coverage after the factory term ends, often for several more years or up to a mileage cap. Extended coverage is most often bought for cars the owner plans to keep well past the factory term, including higher-mileage vehicles.
What Is An Extended Auto Warranty
These contracts cover listed mechanical and electrical breakdowns, but most exclude normal wear and tear, damage from accidents or weather (that is the job of car insurance), and parts that were already failing when the contract was bought. There can be real benefits to having a car covered under an extended warranty, provided the contract fits the car and the owner’s plans. Whether you’re looking for peace of mind, or the security of knowing that your car is protected, an automotive extended guarantee can help you make the right decision.
The main advantage of an auto extended warranty is that it can pay for repairs that the original manufacturer won’t. While an extended warranty may cover some or all of the repairs needed, it does not cover routine maintenance. A common occurrence is when the onboard computer in a car malfunctions in the third year of ownership.
A failure like that in the third year of ownership would normally still be covered by the factory bumper-to-bumper warranty; an extended contract matters once that factory coverage runs out, when a control-module or transmission repair can cost hundreds or thousands of dollars. Hybrid and electric models come with longer factory coverage on their high-voltage parts: Ford and Chevrolet publish 8 years/100,000 miles for hybrid and EV components, and Toyota extended its hybrid battery warranty to 10 years/150,000 miles from the 2020 model year.
Regardless of the length of an auto extended warranty, it is essential to know what it covers. While some warranties will not cover everything, they can give you peace of mind. Whether you want to purchase an extended warranty or not, it is a great way to protect yourself against unexpected expenses.
By taking the time to do your research, you’ll be able to select the best option for your needs. An extension of the factory coverage can be worth having, but it is not automatically worth the price tag: Consumer Reports’ member surveys found that owners typically paid more for the coverage than they got back in direct benefits, so compare the price with the repairs your model is likely to need.
Buying an auto extended warranty gives you peace of mind. A breakdown can be expensive and inconvenient, but with a warranty, you only have to pay a deductible when repairs are needed.
Furthermore, you’ll be able to keep your vehicle in better shape and enjoy a worry-free life. It’s worth checking out an auto extended warranty if you’re a long-term car owner.
A reliable extended warranty is the best way to protect your investment. While a new car will likely come with a manufacturer’s warranty, it’s vital to ensure that you’re getting the best coverage possible.
You can choose a plan that covers the components you worry about most, and some plans add extras such as towing, rental-car reimbursement and roadside assistance; routine maintenance is normally not included and usually has to be kept up, with receipts, to keep the contract valid. If you’re looking for a good deal, you’ve come to the right place to know details procedure of calculating extended warranty cost.
A factory warranty provides peace of mind for many years. Buying an auto extended warranty will also protect you from unexpected repairs. Its value will be dependent on the type of coverage you choose.
As of September 2026, Cars.com reports that plans run from roughly $30 to $250 a month, with an average of $139 a month based on quotes from 11 providers collected in February 2026, and that a three-year contract might cost about $4,360 up front. Whether that outlay is recovered depends on how many covered repairs the car actually needs during the contract term.
When shopping for an extended warranty, consider the price. Some options are better than others, but they’ll be more expensive than a manufacturer warranty.
Some manufacturer-backed plans mirror the factory warranty and simply extend its term; independent plans list their own covered parts, which may be narrower. You should be aware that not all contracts cover the same things, so the covered-parts list and the exclusions list are the two pages to read first.
There are several types of auto warranties. You can buy bumper-to-bumper or stated-component warranties. A bumper-to-bumper (exclusionary) contract covers most parts of the car, including the engine, transmission and electronics, and lists only what is excluded; a stated-component contract lists only what is included.
However, it will usually cover only certain parts of the vehicle, and may not cover the same components as the manufacturer’s warranty. The same goes for car parts and accessories.
Extended warranties are important for many reasons. They offer peace of mind and can be a great way to protect your vehicle. For an owner who cannot absorb a large repair bill, they are one way to protect the investment in the car.
And it can help you to avoid costly repairs that you may not have been able to afford in the first place. Extended warranties are not, on average, a way to save money; their value is budget certainty, since the owner pays a fixed price plus a deductible instead of an unpredictable repair bill. That predictability is the peace of mind buyers are paying for.
What Is an Auto Extended Warranty, Legally?
An auto extended warranty is, in legal terms, a vehicle service contract. The FTC’s consumer guidance states: “Auto service contracts – sometimes called ‘extended warranties’ – are optional contracts sold by vehicle manufacturers, dealers, or independent companies.” The FTC defines a true warranty as “a promise to fix certain defects or malfunctions during a specific timeframe after you buy a vehicle,” and notes that “a manufacturer’s warranty is included in the price of a new vehicle.”
The distinction matters. The Magnuson-Moss Warranty Act of 1975, the federal law governing written consumer warranties, does not treat repair service contracts as warranties, so the contract document alone controls what is paid.
Three kinds of sellers offer extended coverage: the vehicle manufacturer, the dealer (reselling a manufacturer or third-party plan) and independent administrators that sell by phone or online. Consumer Reports notes that the best time to buy protection for a newer vehicle is while the original factory warranty is still in force.
How Long Does a Factory Warranty Actually Last?
A factory warranty lasts well beyond one year on every mainstream brand sold in the US. The table shows terms published by the manufacturers as of September 2026; coverage ends at the time or mileage limit, whichever comes first, counted from the date the car was first put into service.
| Brand | Bumper-to-bumper | Powertrain | Hybrid/EV components | Corrosion |
|---|---|---|---|---|
| Ford | 3 years/36,000 miles | 5 years/60,000 miles (5 years/100,000 miles for Power Stroke diesel) | 8 years/100,000 miles | 5 years/unlimited miles |
| Toyota | 36 months/36,000 miles | 60 months/60,000 miles | Hybrid battery 10 years/150,000 miles (2020 model year onward) | 60 months/unlimited miles (rust-through) |
| Chevrolet | 3 years/36,000 miles | 5 years/60,000 miles | EV propulsion battery 8 years/100,000 miles | Published in the owner warranty booklet |
| Hyundai | 5 years/60,000 miles | 10 years/100,000 miles (original owner) | Hybrid/EV battery 10 years/100,000 miles | 7 years/unlimited miles (anti-perforation) |
Two federal rules add coverage that many owners forget. Under the Clean Air Act emissions warranty (40 CFR 85.2103), emission-control parts are covered for 2 years or 24,000 miles, and specified major emission-control components, namely the catalytic converter, the electronic emissions control unit and the on-board diagnostic computer, are covered for 8 years or 80,000 miles. Federal emissions rules are also why plug-in hybrid and electric-vehicle propulsion batteries carry at least 8 years/100,000 miles of factory coverage; California requires 10 years/150,000 miles.
What Does an Extended Warranty Cover and Exclude?
An extended warranty covers the mechanical and electrical failures listed in the contract, and nothing else. Most sellers use three tiers:
- Powertrain: engine, transmission, drive axles and related internal parts. The cheapest tier; Cars.com quotes averaged $117 a month in February 2026.
- Stated-component (mid-level): the powertrain plus a named list of other systems, such as air conditioning, steering, fuel system and some electronics. Cars.com average: $139 a month.
- Bumper-to-bumper (exclusionary): covers everything except a published exclusion list. Cars.com average: $160 a month.
Common exclusions across all tiers, according to the FTC’s guidance and typical contract terms: routine maintenance (oil, filters, fluids), wear items (brake pads, tires, wiper blades, clutches, batteries), cosmetic damage, damage from accidents, floods or misuse, pre-existing conditions, and problems caused by missed maintenance or unapproved modifications. The FTC also advises checking how parts depreciation and labor costs are handled before signing.
How Much Does an Auto Extended Warranty Cost?
As of September 2026, an auto extended warranty typically costs between $30 and $250 a month, with an average of $139 a month, according to Cars.com’s analysis of quotes requested from 11 warranty companies in February 2026. That works out to roughly $360 to $3,000 a year. Cars.com’s examples show why the range is wide: a Toyota Camry quoted about $125 a month for the cheapest plan, while a Mercedes-Benz GLB quoted $173 to $220 a month depending on tier.
Price depends on the vehicle’s make, model and repair history, its age and mileage, the coverage tier, the term length and the deductible. Consumer Reports notes that extended warranty prices are negotiable, like the price of the car itself, because sellers earn a substantial commission on them.
Is an Extended Car Warranty Worth It?
For most owners of reliable models, an extended car warranty is not worth it financially, based on the best available survey data. A Consumer Reports National Research Center survey of about 12,000 subscribers who had bought an extended warranty (published in 2014) found that more than half never used the coverage; among those who did, the median saving on repairs was $837 against an average contract price of $1,214, a net loss of more than $375. Fewer than a quarter of Honda, Subaru and Toyota owners said they would buy one again.
A contract can still make sense for a model with a documented history of expensive repairs, or for an owner who could not pay for a major repair from savings and prefers a fixed monthly cost. Consumer Reports’ alternative advice is to buy a reliable model, maintain it, and set the money aside for repairs instead.
How to Check an Extended Warranty Before You Buy
- Identify who backs the contract. The FTC advises finding out whether the dealer, the manufacturer or an independent company is responsible for paying claims, and checking that company’s reputation and complaint record with your state attorney general or consumer protection office.
- Read the covered and excluded parts lists. Ask whether the contract is exclusionary or stated-component, and how parts depreciation, labor rates, towing and rental cars are handled.
- Check the deductible basis. Per-repair and per-visit deductibles produce very different bills when several parts fail at once.
- Confirm where repairs can be done and who authorizes them. Some contracts require pre-approval before work starts and limit repairs to certain shops.
- Get the cancellation and transfer terms in writing. Rules vary by state. In California, for example, Civil Code section 1794.41 allows a full refund if the contract is cancelled in writing within 60 days (30 days for a used vehicle without a manufacturer warranty) and a pro-rata refund after that, with no cancellation fee.
The FTC also confirms that you do not have to use the dealer for routine maintenance or repairs to keep a factory warranty in force: “it’s illegal for a dealer to deny your warranty coverage because you had routine maintenance or repairs done by someone else,” and “your warranty stays in effect if you use aftermarket or recycled parts.” Related reading on this site: how to understand car insurance quotes, which explains the separate coverage that handles accident and weather damage, and finding an auto loan that suits you, useful because a service contract added to a loan is financed at the loan’s interest rate. Mechanical breakdown cover is different from car insurance, which pays for collision and weather damage (see the best car insurance companies in the USA), and from a home warranty, which is the same kind of service contract for household systems.
Extended Warranty Robocalls and Scams
Calls and letters that say “we’ve been trying to reach you about your car’s extended warranty” are illegal robocalls, not messages from your manufacturer or dealer. The FTC’s consumer alert states plainly: “The companies behind this type of robocall are not with your car dealer or manufacturer,” and the “extended warranty” being sold is a service contract that “often doesn’t actually cover any problems you have with your car because of the restrictions in the fine print.” The FTC’s advice is to hang up, consider a call-blocking service, and report the call at DoNotCall.gov or ReportFraud.ftc.gov.
In 2022 the FTC sued American Vehicle Protection Corp., alleging it cold-called consumers claiming to represent dealers and manufacturers and promised “full vehicle” protection while the written contract, sent only after payment, listed many exclusions; the FTC put consumer losses at more than $6 million. In October 2024 the FTC sent more than $449,000 in refunds to 18,255 consumers harmed by that scheme.
Buying a Used Car? Check the Remaining Factory Coverage First
Factory warranty periods run from the date the car was first sold, so a three-year-old used car may have no bumper-to-bumper coverage left but two more years of powertrain coverage. Some brands reduce terms for later owners: Hyundai’s 10-year/100,000-mile powertrain warranty applies to the original owner; subsequent owners receive 5 years/60,000 miles. Consumer Reports notes that extended coverage is generally available for used vehicles under 80,000 miles. Before pricing a contract, confirm the in-service date and mileage with a vehicle history report, and follow the inspection steps in making the most of a used car purchase.
Frequently Asked Questions
Is an auto extended warranty the same as a manufacturer’s warranty?
No. A manufacturer’s warranty is included in the price of a new vehicle and is a promise to fix defects for a set time. An auto extended warranty is an optional service contract sold separately, and the FTC notes it may be backed by the manufacturer, the dealer or an independent company.
How much does an extended car warranty cost per month?
As of September 2026, Cars.com reports an average of $139 a month across quotes from 11 providers, ranging from about $30 to $250 a month. Powertrain-only plans averaged $117, stated-component plans $139 and bumper-to-bumper plans $160.
Can I cancel an extended warranty and get a refund?
Usually yes, but the terms depend on the contract and state law. California Civil Code 1794.41, for example, allows a full refund within 60 days (30 days for a used car sold without a manufacturer warranty) and a pro-rata refund afterward with no cancellation fee. Check your own contract and state rules.
Do I have to service my car at the dealer to keep the warranty?
No. The FTC states that it is illegal for a dealer to deny factory warranty coverage because maintenance or repairs were done elsewhere, and that aftermarket or recycled parts do not void it. Extended service contracts may set their own approved-shop rules.
Are the calls about my car’s extended warranty real?
No. The FTC says these robocalls are illegal and the callers are not connected to your dealer or manufacturer. Hang up and report the call at DoNotCall.gov or ReportFraud.ftc.gov.
