When Should You NOT Buy an Extended Warranty? 7 Times to Skip It, Plus Older Car Coverage

Skip an extended warranty when your car is still under factory warranty, when you will sell it within about 18 months, when it is a cheap car near the end of its life, or when the deductible and exclusions leave little real coverage. Buy one when you plan to keep an older car for years and a surprise transmission or engine bill would hurt your budget.

If you are looking for a car warranty for cars over 20 years old, or for a car past 100,000 miles, coverage can still exist. Eligibility depends on the car's age, mileage and condition, so check your exact car before you decide. Below are the 7 times to skip coverage, then how older cars qualify.

Skip It or Consider It: Quick Check

Find your situation in the table, then read the matching section.

1. You Bought a New Toyota, Honda or Lexus With Under 50,000 Miles

This is the big one, and it frustrates warranty salespeople to no end.

Toyota, Honda, and Lexus have earned their reputations for a reason. These manufacturers have some of the most bulletproof reliability records in the industry. A new or nearly-new Toyota with under 50,000 miles on it typically comes with:

• 3-year/36,000-mile basic factory warranty (covers almost everything)
• 5-year/60,000-mile powertrain warranty (engine, transmission, drivetrain)
• 5-year/100,000-mile corrosion warranty (rust perforation)
• 8-year/100,000-mile hybrid battery warranty (if applicable)

Let's say the dealer is pushing a five-year extended warranty for $3,500. Even if you have a catastrophic failure at year three (unlikely), you'd need repairs exceeding $3,500 for the warranty to break even. On these vehicles? That's rare. Most owners will never break even on that investment.

What you are really paying for is peace of mind about a car that is already covered and rarely breaks early. Revisit the question near the end of the factory warranty, when repairs start coming out of your pocket. Our Toyota vs Honda reliability comparison shows how these brands hold up as they age.

2. You Will Sell or Trade In the Car Within 12 to 18 Months

Here's a math problem: If you're buying a five-year extended warranty but selling the car in a year and a half, how much of that warranty will you actually use?

None of it.

Some contracts can be transferred to the next owner for a fee, and CoverageX allows a transfer for a $75 admin fee, subject to approval. That helps the buyer, not you. A prepaid five-year contract you use for 18 months is mostly money you will not get back in full.

This is surprisingly common. People buy cars thinking they'll keep them forever, then life happens. Job relocation. New family situation. Unexpected financial needs. Suddenly that five-year warranty expires six months after you've sold the vehicle.

If there is a real chance you will sell soon, skip prepaid multi-year coverage. If you still want protection for a short time, choose a monthly plan you can cancel when you sell. See how to cancel an extended car warranty and get a refund.

3. Your Car Is Still Under Its Factory Warranty

This one sounds obvious, but it happens all the time.

You walk onto a lot. A 2024 car with 28,000 miles is still sitting pretty under its factory warranty. The dealer asks if you want extended coverage. Some customers say yes because the dealer makes it sound like the factory warranty is about to "run out" or like having "double coverage" is somehow beneficial.

It's not.

You can't stack warranties. You can't make them "work together." The extended warranty doesn't kick in until the factory warranty expires. You're basically financing dead time. You're paying today for coverage that won't apply for another 3+ years.

The exception is a car that has passed the basic factory warranty, which usually ends at 3 years or 36,000 miles, but still has powertrain coverage, which usually runs to 5 years or 60,000 miles. Here a plan that covers electrical, air conditioning and suspension can fill a real gap. A powertrain-only plan would mostly overlap.

Timing matters too. CoverageX plans start covering repairs 30 days after purchase and once the car has been driven 1,000 miles, so buy shortly before the factory warranty ends, not years ahead. Read what to do before your factory warranty expires and the best time to buy an extended warranty.

4. You Do Your Own Repairs or Have a Trusted Mechanic

If you can diagnose problems, do basic repairs yourself or have an independent mechanic you trust, a plan is often worth less to you than to other owners. You pay parts and fair labor instead of dealer rates, and you catch small problems before they become big ones.

Say the transmission fails in year four. A rebuild with labor typically runs $2,300 to $6,000, depending on the car. With a plan, you pay your deductible and the plan pays the rest of the covered repair.

If you already keep that much in savings and your mechanic charges fair rates, you may come out ahead by skipping the plan and paying for the rare big repair yourself. Compare the numbers in our transmission replacement cost guide.

5. You Are Buying a Cheap Car You Will Keep for a Short Time

Economics matter. If you're buying a $6,000 Honda Civic with 120,000 miles that you plan to drive for 2 to 3 years before retiring it, an extended warranty often doesn't make financial sense.

Let's do the math:

• Extended warranty cost: $2,000 to $2,500
• Remaining vehicle value: $4,000 to $5,000
• Your cost basis now: $8,000 to $8,500

If the car needs a $1,500 repair in year two, yes, the warranty would have covered it. But statistically, it probably won't. And if it does need major repairs? You're essentially pouring thousands into a vehicle that might only be worth $3,000 to $4,000 at that point. It makes more sense to simply retire the car and move on.

A plan only makes sense here if you will keep the car for years and could not pay for a major repair. If the car is a bridge until your next one, skip it. When repairs start to pile up, our guide on whether to keep repairing or buy new helps you decide.

6. The Plan Is Cheap but the Car Is Unreliable

This one is a paradox. Some models have weak reliability records, and dealers sometimes offer a five-year plan on them for what looks like a bargain, such as $800 to $1,200.

If you have not bought the car yet, the plan does not fix the real problem. You will still lose time to breakdowns, and a cheap plan on a risky car may come with tight limits. Before you sign, put the money toward a more reliable car instead. Our list of the most reliable used cars under $20,000 is a good place to start.

If you already own the car and plan to keep it, the math changes. See the older car section below.

7. The Contract Has High Deductibles or Long Exclusion Lists

Not all extended warranties are created equal. Some are basically useless garbage that technically exists but won't actually cover anything.

Read the fine print before you sign.

Some extended warranties have:

• Per-repair deductibles of $500 to $750 (meaning you pay that every single time something breaks)
• Extensive exclusions (wear items, scheduled maintenance, anything that was ever remotely near water)
• Limited coverage lists (basically only covers if the engine spontaneously combusts, and even then probably not)
• Unreasonable dealer requirements (you can only use specific dealers, often at inflated rates)

A warranty with a $500 deductible where you're paying $3,000 upfront isn't really that protective. You're essentially pre-paying $3,000 for the privilege of paying $500 out of pocket, plus absorbing some of the cost difference between what the warranty covers and what the repair actually costs.

Do the math on these. If the deductible is more than 10 to 15% of the warranty cost, you're probably overpaying for the protection you'll actually receive.

Ask whether the deductible is charged per visit or per repair, and which shops you can use. Our guide to extended warranty deductibles explains the options, and these extended warranty red flags help you spot a weak contract.

When an Extended Warranty Still Makes Sense on an Older Car

The seven cases above are about not wasting money. The other side is just as real: an older car you plan to keep is where a plan can pay for itself.

Coverage makes the most sense when all three of these are true:

• You plan to keep the car for several more years.
• The car is near or past the end of its powertrain warranty. For example, a 2019 Dodge or RAM with 60,000 miles is already past a 5-year/60,000-mile powertrain warranty.
• A surprise $3,000 to $5,000 repair would go on a credit card or wipe out your savings.

In that case, a monthly plan is not a luxury. It turns an unpredictable repair bill into a fixed monthly cost.

10-Year-Old, 15-Year-Old and 20-Year-Old Cars

The average driver puts about 12,000 to 15,000 miles a year on a car, according to the EPA. That gives a rough idea of where a car of each age stands.

What Mileage Matters Most

Mileage usually matters more than age. 100,000 miles is the first big milestone, when parts like the timing belt and water pump often come due. See what happens to your car at 100,000 miles.

The repairs that make or break the decision are the big ones. A transmission rebuild with labor typically costs $2,300 to $6,000.

A remanufactured engine runs about $3,000 to $5,500. See our engine replacement cost guide.

Many vehicles run well past 200,000 miles with proper maintenance. A high-mileage car with good records can be worth protecting. Read more in our guide to the extended warranty for high-mileage cars.

Common Exclusions and Limits on Older Car Coverage

Every plan has limits, and they matter more on an older car. Before you buy, know what is not covered:

• Problems the car already has. Pre-existing problems are excluded, so a plan cannot fix a leak or noise you already know about.
• Maintenance and wear items. Oil changes, brake pads, tires and wipers are not covered.
• Cosmetic damage. Dents, paint, upholstery and glass are excluded.
• Accidents. A service contract is not car insurance. It does not cover collisions or liability.
• Waiting period. CoverageX coverage starts 30 days after purchase and after the car has been driven 1,000 miles.
• Parts and labor limits. Repairs may use parts of like kind and quality, including remanufactured parts, and labor rate caps apply.

Rental car benefits and which breakdowns qualify can also vary with the car's age, mileage and the plan you choose. Read the sample contracts for the exact terms.

How to Check If Your Older Car Qualifies

Checking takes a few minutes and costs nothing:

1. Note the model year and the current odometer reading. Every provider sets its own age and mileage limits.
2. Gather your service records. Proof of regular oil changes and maintenance helps if you ever file a claim.
3. Fix or document known problems first. Anything already wrong will be excluded. If you are buying the car, use our used car inspection checklist.
4. Get a quote with your year and mileage at buy.coveragex.com. It takes about two minutes and there is no obligation.
5. Ask about eligibility for your exact car. CoverageX Member Services can check it at 1-800-258-2084.
6. Compare plan levels. Essential covers the engine, transmission and drivetrain. Signature adds electrical, air conditioning and suspension. Premium and Executive cover more. See all CoverageX auto protection plans.

CoverageX does not sell vehicle service contracts in California. California drivers can be referred to a licensed mechanical breakdown insurance provider.

How to Decide: 5 Steps Before You Sign

Here's what I recommend instead of the binary yes/no decision:

1. Know what you're actually buying. Understand what the warranty covers, what it costs, what the deductibles are, and when it applies.
2. Run the numbers for your specific vehicle and timeline. How long do you actually plan to keep it? What's the reliability history of that specific make, model, and model year? (Look this up on Consumer Reports, check forums, talk to owners.)
3. Understand your financial vulnerability. Can you absorb a surprise $2,000 to $4,000 repair without significant hardship? If yes, you probably don't need the warranty. If no, it becomes more attractive.
4. If you decide to buy, compare quotes. Prices for the same coverage vary, so ask for the deductible, the exclusions and the cancellation terms in writing before you sign.
5. Always consider the alternative. That $2,500 warranty cost could become a repair fund. Invest it in an emergency fund for car maintenance instead, and you might come out ahead. Compare the two approaches in extended warranty vs emergency fund.

A new Toyota under factory warranty usually does not need a plan. A 10-year-old car you plan to drive for five more years, with no savings for a big repair, is a different story. Decide based on your car and your budget, not on pressure at the dealership.

The Bottom Line

Skip an extended warranty when the factory warranty still covers you, when you will sell soon, or when the plan costs more than the car is worth. Consider one when you will keep an older car for years and a big repair would strain your budget.

If you do want coverage, learn how to compare extended warranty quotes so you can judge any plan on its terms, not on the sales pitch.

Older Car Warranty: Frequently Asked Questions

Can I get a warranty on a 20-year-old car?

Sometimes. Each provider sets its own age and mileage limits, so a 20-year-old car with low miles and a good service record has the best chance. Get a quote with your year and mileage at buy.coveragex.com, or call CoverageX Member Services at 1-800-258-2084 to check your exact car.

Can you get an extended warranty on a car with over 100,000 or 150,000 miles?

Yes, plans for high-mileage cars exist, but limits vary by provider and plan. Big repairs like the transmission and engine become more likely past 100,000 miles, which is when coverage is most useful. See our guide to the extended warranty for high-mileage cars.

What is considered high mileage for a car?

There is no fixed number, but 100,000 miles is the usual milestone. The average driver covers about 12,000 to 15,000 miles a year, so a 100,000-mile car is roughly 6 to 8 years old. Many cars last well past 200,000 miles with proper maintenance.

Is it bad to buy a car with high mileage?

No, not if it has been maintained. Service records and a pre-purchase inspection tell you more than the odometer. Use our used car inspection checklist and read what to know before buying a used car with 100k miles.

Is an extended warranty worth it on an older car?

It is worth it if you plan to keep the car for years and could not easily pay for a major repair. It is usually not worth it on a cheap car you will replace soon, or if you have savings and a mechanic you trust. Use the quick check table at the top of this page.

Will an extended warranty cover problems my car already has?

No. Pre-existing problems are excluded. CoverageX coverage also starts only after a waiting period of 30 days and 1,000 miles, so buy before a problem shows up. See how to file a claim for the full process.

How do deductibles work on an older car plan?

You pay one deductible per claim directly to the repair shop, and CoverageX pays the shop for the rest of the covered repair. Older cars tend to need repairs more often, so a lower deductible can make sense. Compare the options in our extended warranty deductibles guide.

Can I cancel if I sell the car or change my mind?

Yes. CoverageX plans are paid monthly and you can cancel anytime. Refund terms for payments already made are set out in your contract. Read how to cancel an extended car warranty for the steps.
