CornerStone United Extended Auto Warranty Review

To learn more about our editorial integrity policy and how we make money through affiliate partnerships, read our full disclosure here.

Extended warranty contracts rarely cover high-mileage, modified, or recreational vehicles. CornerStone United aims to fill that service gap. It has been supplying warranty contracts since 1973 across the US and Canada.

While CornerStone United may be one of your only options for RV and lifted vehicle protection plans, is the coverage worth the premium? The best extended car warranty companies provide peace of mind by offering a hassle-free claims process and extensive coverage.

This article will provide a closer look at CornerStone United reviews, costs, coverage, and more to help you determine if the provider is right for your needs.

CornerStone United provides auto warranty coverage for vehicles that may not find coverage anywhere else. While some providers offer coverage for high-mileage vehicles, few also include options for vehicles with lifts or RVs. If this applies to you, CornerStone may be one of your only choices.

Based on customer reviews and the prices we were able to gather, CornerStone has competitive rates and average service. Not everyone has been pleased with their CornerStone United coverage, but the company appears to do a solid job paying out claims. Many customers whose claims were denied did not seem to have fully understood their vehicle service contracts.

CornerStone United certainly does not have the kind of negative reputation that we see with other extended warranty providers. It seems like a safe bet for your vehicle. However, there are other reputable companies out there. If you are insuring a standard vehicle that is not especially old, you should look at all of your options before making a final decision. It’s likely you’ll find better coverage elsewhere.

CornerStone United, based in Hickory, North Carolina, has a wide range of coverage options and add-ons available for drivers across the US and Canada. The mission statement for the company is to specifically provide coverage for vehicles that aren’t covered anywhere else. As such, the list of excluded vehicles is a lot shorter than you will find with other companies.

All warranty programs are insured by companies with an AM Best financial strength rating of A- or better. This means that CornerStone administrators and insurers should have no issue paying out claims. All coverage plans are sold through agents, dealers, manufacturers, distributors, or auctioneers, so you can’t purchase a policy from CornerStone United directly.

CornerStone United also sells Ultimate Wrap and Ultimate Certified Wrap packages. These types of coverage are intended to supplement manufacturer powertrain warranties. They include coverage for all components besides those that are part of the powertrain.

Many manufacturer warranties come with separate bumper-to-bumper and powertrain warranties. The powertrain coverage will usually last a couple of years longer than the bumper-to-bumper warranty. This is where a “wrap” package could be useful. It will effectively replace the bumper-to-bumper coverage.

In addition to the four main plans outlined in the chart above, there are a host of other coverage options offered by CornerStone United:

CornerStone United is slightly better than average when it comes to cost. An extended auto warranty from this provider will likely cost between $1,700 and $1,900, according to reviewers. There are four deductible options for CornerStone United warranty plans: $0, $50, $100, and $200.

Remember, CornerStone plans are sold through manufacturers, agents, and dealerships. There is no way for you to get a free quote online. The final cost of your contract will likely depend on your location, vehicle make, model, mileage, and the terms of your coverage.

Although we couldn’t get a quote for a CornerStone extended warranty, we found several customer reviews through the Better Business Bureau (BBB) that detailed costs for automobiles and recreational camping vehicles.

A CornerStone United contract must be purchased through a manufacturer, agent, or dealership. To find an agent near you, reach out to CornerStone online or by calling 877-667-1762. When you call an agent for a quote, be prepared with your vehicle year, make, model, and mileage, as well as your vehicle identification number (VIN).

Once you have a CornerStone plan and wish to file a claim, you can head to any repair shop certified by the National Institute for Automotive Service Excellence (ASE®). Give your policy information to the mechanic, and they will contact CornerStone. If your claim is approved, CornerStone will pay the mechanic directly, and you will pay only your deductible.

CornerStone United has an A+ rating from the BBB. The customer review score is about average at 3.0 out of 5.0 stars, but this is based on very few reviews.

Customer complaints against CornerStone are typical for an extended warranty company. Some vehicle owners complain about a lack of coverage or claims denial, but others report positive experiences. Here are two examples:

“We got the repair without prior authorization… [CornerStone] denied it, stating that we did not get prior authorization. I wrote a letter stating the circumstances [and] asked that they escalate the claim and reconsider since it was the dealer who failed to get the authorization. They were awesome and accepted the claim and reimbursed me for my out-of-pocket cost minus the deductible.” - Shannon and Joe L. via BBB

“I bought the top-of-the-line warranty. Every claim I have made was denied or reduced.”- Chad W. via BBB
