Used Car Warranty: What It Covers, What It Costs, and Whether You Need One

A used car warranty pays for certain repairs after the factory coverage has ended or if the car never had any. Plans typically run about $950 to $2,000 per year, and they don’t cover routine maintenance or normal wear.

The term is used loosely, though. A “used car warranty” might be leftover factory coverage, a dealer’s promise, a certified pre-owned program, or a third-party contract that isn’t legally a warranty at all. This guide explains each so you know what you’re actually buying.

Types of Used Car Warranties

1. Remaining factory warranty. If the car is still within the manufacturer’s time and mileage limits, the coverage often carries over to you. Ask the dealer for the warranty paperwork, then verify the expiration date and mileage with a dealership using the car’s VIN.
2. Certified pre-owned (CPO) warranty. Franchised dealers sell these manufacturer-backed vehicles after a multi-point inspection. CPO coverage usually adds extended benefits on top of any remaining factory warranty, and it’s typically the most dependable option.
3. Dealer warranty. This is short-term coverage the dealer provides at purchase, from either an independent or franchised lot. Most are limited warranties, so read exactly which systems are included and what share of repair costs the dealer pays.
4. Third-party extended warranty (service contract). Outside companies sell these independent contracts, usually with a flexible network of repair shops. Strictly speaking, a service contract is a promise to pay for or perform certain repairs. It is not a warranty, even though people call it an “extended warranty.” You can buy one at almost any time.

What a Used Car Warranty Usually Covers

• Engine and transmission components
• Drivetrain and steering components
• Electrical systems
• Air conditioning

Coverage varies a lot by plan. “Bumper to bumper” doesn’t necessarily mean every part, so check the exclusions list.

What It Usually Doesn’t Cover

• Routine maintenance: oil changes, filters, tune-ups
• Wear-and-tear parts: brake pads, tires, clutch discs, wiper blades
• Damage from accidents, neglect, or unauthorized modifications

How Much Does a Used Car Warranty Cost?

Used car warranty plans commonly cost roughly $950 to $2,000 per year. Price depends on the vehicle’s age, mileage, and reliability record, the coverage level, the deductible, and who sells the plan. Dealers and third parties may both price add-on coverage high, so compare quotes rather than accepting the first offer.

Understanding the Buyers Guide (Dealer Sales)

Under the FTC’s used car rule, dealers must display a Buyers Guide in every used car they sell and give you a copy after the sale. It covers light-duty vans and trucks, demonstrators, and program cars. It isn’t required for motorcycles and most recreational vehicles. Maine and Wisconsin dealers use their own versions.

The guide tells you:

• Whether the car is sold “as is” or with a warranty
• What percentage of repair costs the dealer will pay under that warranty
• Which major systems to watch for problems
• To get every promise in writing, since spoken promises are hard to enforce
• To get an independent inspection and a vehicle history report
• The dealer’s contact information, including for complaints

The Buyers Guide overrides your sales contract. If the guide says the car has a warranty and the contract says “as is,” the dealer must honor the used car warranty in the guide. Make sure any negotiated changes appear in both documents.

“As Is” vs. Implied vs. Full and Limited Warranties

As is. The dealer pays for nothing after the sale. You carry all the risk. If the dealer verbally promised a repair or a refund, get it written on the Buyers Guide.

Implied warranties. If the car isn’t sold “as is” and has no written used car warranty, unwritten implied warranties still apply. The two common ones are the warranty of merchantability (the car will perform its basic functions) and the warranty of fitness for a particular purpose (the car suits a use the dealer recommended, like towing). To claim one, you generally have to show the problem existed at the time of sale. Duration varies by state, and in some it can reach four years.

Full vs. limited warranty. A full warranty is rare. It covers anyone who owns the car during the warranty period, provides free service (including removal and reinstallation), offers replacement or refund after a reasonable number of failed repair attempts, requires only that you notify the dealer, and has no time limit.

If any one of those isn’t true, the used car warranty is limited, which is what most used car warranties are. Either type can cover only certain systems.

Service contract bonus. If you buy a service contract from the dealer within 90 days of purchase, the dealer can’t disclaim implied warranties on the systems that contract covers, even if the car was sold “as is.” That can give you protection beyond the contract itself.

Is a Used Car Warranty Worth It?

It may be worth it if:

• The car has high mileage or a reputation for expensive repairs
• You don’t have an emergency fund to absorb a sudden repair bill of $1,500 or more
• The plan is from a reputable provider with clear terms

You may want to skip it if:

• The model has a strong reliability record
• The claim terms are restrictive or the exclusions long
• You’d rather put the same money into a dedicated repair savings account

Questions to Ask Before Buying a Service Contract

• Does it duplicate coverage you already have, or start after the current warranty ends?
• Is it transferable if you sell the car? Is a shorter term available?
• Which parts and systems are actually covered?
• What’s the deductible, and is it per visit or per repair?
• Does it cover towing and rental cars?
• Must repairs and maintenance be done at the dealer?
• What are the cancellation and refund terms, and are there fees?
• Is the seller reputable, and have you checked complaints with your state or local consumer protection office?

Before You Buy: Protect Yourself

1. Get an independent mechanical inspection. A vehicle history report shows accidents and flood damage, but usually not mechanical problems. A “certified” label or a warranty doesn’t replace an inspection. Ask for a written report with repair cost estimates, which you can use to negotiate.
2. Ask for out-the-door prices in writing and confirm the car is actually on the lot.
3. Watch for add-ons like gap insurance, VIN etching, and rustproofing. You can usually buy the car without them, and most are sold cheaper elsewhere.
4. Ask about the return policy. Federal law gives no three-day right to cancel. Some states do require one, so check with your state attorney general.
5. Get everything in writing, including warranty documents and confirmation that any service contract is active.

What to Do If You Have a Problem

1. Follow the instructions in your warranty or service contract.
2. For manufacturer-backed coverage, contact the dealership, which decides service and repairs.
3. Contact your state attorney general’s consumer protection office.
4. Try a dispute resolution organization. Many warranties require this before you can sue.
5. Consider small claims court for smaller amounts.
6. Under the federal Magnuson-Moss Warranty Act, you may sue over breach of express or implied warranties or service contracts and recover attorneys’ fees if you win. Ask a lawyer whether it applies.

FAQ

How much does a used car warranty cost?

Usually about $950 to $2,000 per year, depending on the car, coverage, and provider.

Is a used car warranty worth it?

It can be for high-mileage or repair-prone cars, or if a surprise bill would strain your budget. It’s less compelling for reliable models with restrictive plan terms.

What does “as is” mean?

The dealer won’t pay for any repairs after the sale. The Buyers Guide’s “As Is” box will be checked.

Is an extended warranty really a warranty?

No. It’s a service contract, a separate promise to perform or pay for repairs, and prices and coverage vary widely.

Can I buy coverage after I’ve bought the car?

Yes. Service contracts can be bought at any time, though buying from a dealer within 90 days of purchase preserves implied warranties on the covered systems.

Does a used car warranty cover brakes and tires?

Generally no. Brake pads, tires, clutch discs, and wiper blades are wear-and-tear items.

Does a CPO car still need an independent inspection?

It’s still a good idea, since the dealer’s certification isn’t independent.
