After your manufacturer warranty expires, an aftermarket auto warranty foots the bill for car repairs. You’re only responsible for a deductible per repair visit and the cost of the contract.

Are Aftermarket Auto Warranties Worth It?

An aftermarket auto warranty can offer car owners the ultimate peace of mind on the road, especially as their vehicles age and factory warranty coverage expires. Typically, the most costly repairs are needed later on in a vehicle’s life. If you don’t have extended warranty coverage, you’ll be stuck paying for repairs out of pocket if your car breaks down.

According to RepairPal, these are some of the most commonly reported problems of popular vehicles and their average repair costs:

Vehicle Repair Average Repair Cost
Honda Accord Ignition switch replacement $158 to $203
Ford Focus Window regulator replacement $372 to $462
Toyota Corolla Air conditioning compressor replacement $576 to $845
Chevrolet Silverado Ignition coil replacement $978 to $1,289
Nissan Altima Engine oil cooler replacement $676 to $707


If you wouldn’t feel comfortable paying these repair bills, an aftermarket auto warranty may be worth considering.

You should also take your existing warranty coverage into account. Most manufacturers offer a 3-year/36,000-mile bumper-to-bumper warranty and a 5-year/60,000-mile powertrain warranty with new vehicles. If you plan on selling your vehicle before the factory warranty expires, there’s little reason to buy an aftermarket auto warranty.

What Does an Aftermarket Car Warranty Cover?

Aftermarket car warranty coverage depends on the type of contract you purchase. Vehicle service contracts can be broken down into three types of coverage:

  • Exclusionary coverage: Also called “comprehensive” or “bumper-to-bumper” coverage, this type of plan covers all major mechanical parts and systems, except for a short list of exclusions.
  • Stated-component coverage: Each covered part and component is specifically listed in the vehicle service contract.
  • Powertrain coverage: The most basic level of protection, this warranty covers a vehicle’s most important systems – the engine, transmission and drivetrain. 

The best aftermarket car warranty providers also offer additional mid-tier plans that give drivers more opportunity to meet their individual coverage and cost needs.

What’s Not Included in an Aftermarket Auto Warranty

Exclusions vary from provider to provider, but there are some parts and causes of damage that the majority of providers won’t cover, including:

  • Wear-and-tear parts
  • Environmental damage
  • Collision damage
  • Vandalism
  • Improper maintenance or misuse
  • Aftermarket parts or modifications



FAQ: Best Aftermarket Car Warranty

What is the best aftermarket auto warranty?

Our review team named Endurance the Best Provider overall, and the company earned a 9.6 out of 10.0-point rating. We like Endurance’s business model, as it works with customers directly rather than through a middleman. The provider offers six coverage plans with term limits over 200,000 miles, ensuring customers can find a contract tailored to their needs.

Are aftermarket car warranties any good?

For many drivers, aftermarket car warranties are a worthwhile investment. They protect you from paying for out-of-pocket repairs after your factory warranty expires. However, the best aftermarket car warranties go beyond financial protection. They also include added perks, including roadside assistance, rental car reimbursement, travel interruption reimbursement and more.

What is a good price for an extended auto warranty?

Based on our research, extended auto warranties cost between $1,700 and $4,000 for three to seven years of coverage. A good price for coverage should be around $2,500 to $3,000. However, extended warranty costs are highly variable, and it may be worth investing more in a high-quality contract.




The Detroit Bureau collects data from every major car warranty provider to formulate rankings of the best warranty companies.

We recommend auto warranty companies based on these rankings, but we also encourage you to perform your own research and compare quotes to find the best coverage.
