When you buy a used car, you may not know the whole story about its current condition. Hidden defects can become a nightmare. It’s also probable that the car is no longer protected under a warranty. While many states have protections against “lemons,” an extended warranty for a used car may be your only hope for keeping repair costs low

We’ll walk you through the ins and outs of getting an extended warranty for a used car from six top-rated auto warranty companies.

Finding the Right Extended Warranty for Your Used Car

There are three types of car warranties you’ll come across in your search.

Dealer Warranty

The worst case scenario when buying a used car is that it doesn’t even make it through the drive home. One of the most basic forms of a car warranty is one covered by the dealership. These usually cover limited repairs, and coverage ends within a few months or years after the purchase.

Manufacturer’s Warranty

A manufacturer’s warranty or factory warranty comes at no additional cost with the purchase of a new car, and it covers repairs and replacements due to faulty factory materials or workmanship. An extended manufacturer’s warranty or service contract, however, offers continued coverage at an extra cost. Be aware that while coverage is usually comprehensive, these warranties tend to be more expensive than warranties from third parties.

Third-Party Warranty

This type of extended auto warranty can be administered by a broker or a company that directly handles repairs. A broker will help you choose a coverage plan that we normally see backed by an insurance company. In other words, the broker itself is just an intermediary. 

Because independent extended car warranty companies are not highly regulated, their reliability varies. Some companies have the financial responsibility to meet claims and others do not, according to the South Carolina Bar, so you should check the Better Business Bureau for ratings and customer complaints.

Used Car Coverage Options

Before you decide on a coverage plan for your used vehicle, you should have a local repair shop do a health check. You’ll learn about any warning signs or weaknesses that could leave you stranded on the side of the road in the future. Plus, you’ll gain better insight into the level of coverage you need.

There are several types of vehicle service contracts, but most companies focus on these few: 

  • Powertrain/Drivetrain—This warranty covers the engine, transmission, and related components. These warranties are usually cheaper, as they don’t include electrical systems, braking systems, heating/cooling, etc. They tend to last 5 years or 60,000 miles on average.
  • Powertrain Plus—These are common coverage plans offered by independent companies. They include powertrain coverage and additional components, such as air conditioning, electrical systems, and fuel delivery systems. It’s still a step below full coverage.
  • Bumper to Bumper—Sometimes called exclusionary plans, you’ll get a short list of components that are not covered rather than a list of items that are covered. It’s closest to the full coverage offered by many manufacturers. Though more expensive, this protection can be the difference between a small deductible and a $3,500 repair.

Always read the contract before making a decision so that you don’t fall victim to certain limitations. Vehicle service contracts often have the following exclusions and limitations:

  • Repairs due to normal wear and tear (covers only a mechanical breakdown) or pre-existing conditions
  • Commercial vehicles
  • Items like brake pads, tires, etc.
  • Ineligibility for owners who failure to perform regularly scheduled maintenance
  • Limited choices for local repair shops
  • Mileage limits

What to Look for in a Warranty

If you believe buying an extended auto warranty will help you breathe a bit easier, then you should know the criteria for a good coverage plan.

What should you look for?

  • Search a company’s BBB rating to gauge trustworthiness or see common customer complaints.
  • Service contracts underwritten by insurance companies are more reliable, so stick to those. Insurance regulations require companies to maintain enough financial reserve to pay your claim.
  • Is there a mileage limit on the contract? Some companies provide coverage for high-mileage vehicles—protection your used vehicle probably requires.
  • Find a service contract that pays for the repairs up front rather than reimbursing you later. Reimbursement could take months in some cases.
  • Look for a service contract with low deductibles, especially if a deductible is required for each repair. Your repair should cost more than the deductible.
  • Some extended warranty companies do not allow you to choose your own repair facility. Companies that offer more flexibility are a better option. 

These are all important factors to consider during your research. Don’t allow price to be your only driving factor when buying an extended auto warranty.

What to Avoid When Buying an Extended Auto Warranty

Just as there are many features to look for in a service contract, there are also red flags to avoid. It can be costly to succumb to the pressure of buying an extended warranty right away. 

Avoid these warning signs and drawbacks:

  • Deceitful coverage (e.g. a contract that covers the engine but excludes most of its internally lubricated items)
  • Contracts that don’t allow cancellations or typical 30-day refunds
  • Contracts that don’t explicitly explain the claim process
  • Pressure to buy coverage immediately over the phone
  • Warranties that are non-transferable
  • Lack of roadside assistance, rental reimbursement, travel interruption service, or towing reimbursement
  • No choice of repair facility or extreme limits when away from home
  • Sample contracts that aren’t readily available 

Remember: the most important thing you can do is read the entire contract.

FAQ: Used Car Warranty Companies

How do I know if the used car I want to purchase already has a warranty?

When purchasing a used car from a dealership, you will typically find a Buyer’s Guide sticker on the car. This guide will tell you whether the vehicle is covered by a warranty or if it’s being sold “as is.”

What is an aftermarket warranty? 

An aftermarket warranty is from a third -party company. These warranties do not always use Original Equipment Manufacturer (OEM) parts. This shouldn’t have any serious effects, but it isn’t always ideal to have parts that are not specifically made for your car. 

Is AA Auto Protection part of AAA?

No. They are separate companies that offer different vehicle services. 

What is the difference between a certified pre-owned vehicle (CPO) and one that’s not?

A CPO vehicle is likely to come with a manufacturer’s warranty and a pre-inspection. You will pay a premium for these used vehicles over a non-certified used vehicle.

Will my warranty coverage start right away?

Most extended warranties do not start until after 30 days or a certain number of miles (usually 3,000).

What is the cost of an extended warranty? 

An extended car warranty can cost from $300 to over $1,000.
