If you’re ready to purchase a used car warranty, it’s crucial that you look at the industry’s best extended car warranty companies. Do you know the difference between a trustworthy source and one marked with red flags?

5 Best Extended Car Warranty Companies

The best extended car warranty plans come from CARCHEX, AutoAssure, Concord Auto Protect, Endurance, and Protect My Car. We compiled our list after considering coverage plans, costs, and customer reviews for the top aftermarket warranty providers in the market.

Below, we’ll briefly explain why each extended warranty provider stands out.

#1 CARCHEX: Industry-Leading Experience and Reputation

Founded: 1999

Headquarters: Baltimore, Maryland

BBB Rating: A+

It’s been over 20 years since CARCHEX started protecting drivers, and it’s consistently ranked as one of the best extended car warranty companies. Drivers receive a strong commitment to “Customer Experience Above All,” as seen by the A+ rating and accreditation offered by the Better Business Bureau (BBB).

CARCHEX customers can choose from five coverage levels, from the bumper-to-bumper coverage found in the Titanium plan down to the Bronze powertrain plan. Each of the best extended car warranty options from CARCHEX come with roadside assistance, towing coverage, rental car reimbursement, fuel delivery services, and trip interruption benefits. The CARCHEX claims process is straightforward, efficient, and generally receives positive reviews.

Excellent customer service scoresSome providers have more plans
Wide-ranging coverage plans
Deep experience in the business

From an exceptional customer service reputation to industry expertise, it’s tough to beat a CARCHEX extended warranty plan.

#2 AutoAssure: Strong Coverage, Questionable Services

Founded: 2010

Headquarters: Plano, Texas

BBB Rating: Not rated

AutoAssure extended warranties typically come with the backing of high-quality contract providers, so you’ll be sure to receive quality care from the company. Customer complaints usually get resolved to the complete satisfaction of customers, though the BBB’s lack of a ranking for AutoAssure makes this tough to verify.

While AutoAssure stands as one of the best extended car warranty companies around, its sales tactics leave much to be desired. Lawsuits have been filed against AutoAssure for falsely telling customers that their extended warranty was about to expire when this was not the case. While coverage itself is top-notch from AutoAssure, the company’s integrity has been called into question.

AutoAssure ProsAutoAssure Cons
Strong complaint resolutionUncertain scores from the BBB
Well-regarded coverageQuestionable sales tactics

There’s plenty to like about AutoAssure, but its commitment to customer service isn’t particularly strong.

#3 Concord Auto Protect: Excellent but Risky Warranty Plans

Founded: 2013

Headquarters: King of Prussia, Pennsylvania

BBB Rating: B

Plans backed by Concord Auto Protect offer a lot of benefits. In fact, the company’s flat tire support, jump-start services, and lockout assistance aren’t even offered by some of the best extended car warranty plans. There’s also a good number of positive customer reviews for Concord Auto Protect online.

This all comes with some risks, as Concord Auto Protect isn’t backed up by an insurance provider. In other words, you’re simply hoping that the company has enough money on hand to back your vehicle service contract. While it’s likely that customers won’t run into issues, the potential exists with Concord Auto Protect.

Concord Auto Protect ProsConcord Auto Protect Cons
Added coverage benefitsVery little insurance backing
Mostly positive customer reviewsAverage BBB score

Concord Auto Protect’s three coverage levels are both extensive and well regarded, but it’s still a risky choice.

#4 Endurance: Nice Benefits with Average Service

Founded: 2006

Headquarters: Northbrook, Illinois

BBB Rating: C

With an Endurance extended warranty, drivers receive one year of free benefits such as key fob replacement, collision discounts, and limited total loss protection. The company’s six coverage plans also make it one of the best extended car warranty companies, as they cover everything from the powertrain over to routine maintenance needs.

Endurance complicates matters with a somewhat mediocre customer experience, however. It’s not particularly reassuring to choose a provider with a C rating and no accreditation from the BBB, and the Endurance claims process doesn’t receive the highest marks.

Endurance ProsEndurance Cons
Wide spread of warranty plansPoor BBB ranking
One free year of benefitsTroubling claims process

You’ll likely be fine with an Endurance warranty, but the best extended car warranty companies typically have stronger claims procedures.

#5 Protect My Car: Expensive, High-Quality Warranty

Founded: 2005

Headquarters: St. Petersburg, Florida

BBB Rating: A+

Don’t expect to save money on a Protect My Car extended warranty plan. The company often has drawn-out payment periods which end up costing more than other best extended car warranty plans. Some customers may view Protect My Car as worth it, since it receives favorable reviews from drivers.

Protect My Car holds an A+ rating from the BBB, though it lacks accreditation. While the customer service commitment offered by Protect My Car stands out, other companies such as CARCHEX also hold high standards and tend to charge much lower rates.

Protect My Car ProsProtect My Car Cons
Long-term payment plansSignificantly more expensive
Respected warranty coverageFew coverage plans

While it can be somewhat costly, Protect My Car definitely stands as one of the best extended car warranty choices.

What Is an Extended Car Warranty?

An extended car warranty pays for mechanical breakdowns that occur after the expiration of your factory warranty, which typically lasts for around 3 years/36,000 miles. While auto insurance companies sometimes pay for damages caused by accidents or the environment, they’ll never cover mechanical breakdowns.

That’s where the best extended car warranty providers step in. Companies such as CARCHEX will protect your vehicle from issues that often pop up with older cars. With an extended warranty, you won’t have to pay for most repair costs and will only be responsible for your deductible and a small monthly payment.

Extended Car Warranty Average Costs

Costs for the best extended car warranty plans largely depend on your chosen provider and level of coverage. In our 2021 car warranty survey, we polled 1,000 consumers and nearly half paid between $1,500 and $2,500 for their extended vehicle service plans.

Factors That Affect Car Warranty Costs

There’s no set amount that the best extended car warranty goes for, as prices are specifically calculated for each individual situation. However, the following are some elements that help determine how much you’ll pay:

  • Level of coverage: The more extensive your coverage, the higher the price you’ll likely pay.
  • Length of coverage: The best extended car warranty plans that last for many years will probably cost more than shorter options, though it’ll likely be less per month.
  • Make, model, and age of your vehicle: Certain types of vehicles will cost more to cover, so the best extended car warranty companies will charge a rate specific to your own.
  • Mileage on your car: Models with greater mileage on them will be more prone to mechanical breakdowns, so they’ll have higher extended warranty costs.
  • Deductible amount: Higher deductibles lead to a lower monthly rate, though you’ll be liable for more money when a breakdown occurs.

Extended Car Warranty Benefits

Many of the best extended car warranty plans come with several benefits to complement your coverage. Below are some of the perks offered to CARCHEX customers:


  • Your choice of auto repair shop
  • Claims paid directly to the repair facility
  • Money-back guarantee
  • Affordable payment options
  • Free quotes that offer affordable rates

  • Roadside assistance
  • Towing coverage
  • Rental car reimbursement
  • Gas delivery
  • Trip interruption services

CARCHEX stands as the best extended car warranty provider because it offers a plethora of services with all five coverage plans. Rather than cutting corners, we’d prefer to offer superb extended warranty coverage to every single CARCHEX customer.

Extended Car Warranty Exclusions

Plans from the best extended car warranty providers almost always cover your vehicle’s powertrain components such as the engine, transmission, alternator, and drive axle. Higher-level plans can cover nearly everything in your car, so choose a bumper-to-bumper protection plan if you’re looking for extensive coverage.

Even the best extended car warranty has some exclusions, though. Below, we’ll explain the most common:

  • Wear and tear components: You’ll usually need to cover brake pad replacements, new windshield wipers, and other parts that break down after some time. Some plans from CARCHEX cover wear and tear components.
  • Damage due to poor maintenance or misuse: If you fail to maintain your vehicle, the best extended warranty plans won’t resolve these preventable issues.
  • Problems from a collision or the environment: Damages from car accidents, flooding, and hail may be covered by car insurance, but they’re excluded from the best extended warranty plans.
  • Excluded components: Bumpers, headlights, tires, and glass will almost never be covered by even the top vehicle protection plans.

Remember that extended warranties are intended to cover mechanical breakdowns, not damages from outside factors. CARCHEX stands ready to protect cars as parts begin to fail, so make sure to pick up one of the best extended car warranty plans if you’re looking for some peace of mind.

How To Use a CARCHEX Extended Warranty

The exact way that each of the best extended car warranty plans from CARCHEX work depends on your contract administrator. However, your claims process will likely look similar to what’s listed below:
