CNA National Warranty Ratings and Reviews

CNA National Warranty Corporation holds an A+ rating from the Better Business Bureau (BBB). Despite the company’s high BBB score, there are few positive reviews from customers who have purchased CNA National Warranty services. However, the company also has few legitimate complaints filed against it.

CNA National Warranty has received about 50 complaints in the past three years. Most customers who complain are upset by unsolicited robocalls that claim to be made on behalf of CNA National Warranty Corporation. But the BBB has posted a notice saying that BBB personnel have investigated the matter and concluded that CNA “does not make telemarketing calls and does not use a third party to make such telemarketing calls on its behalf.”

This is an important indication of CNA National Warranty being a legitimate company. Usually, it is inadvisable to contact companies that practice unsolicited sales call tactics.

There are a few other customer reviews that mention poor claims servicing, but based on the low volume of these complaints, it’s unlikely that the majority of customers have negative service experiences.

Positive CNS Warranty Services Reviews

“My extended warranty has covered everything without any negative feedback, and every customer service representative I have talked to has been very helpful and polite. I have never had such a big mechanical issue before, and having a company be so helpful has been amazing.” – Caityln C. via BBB

“By far the best aftermarket warranty company out there. [I] have four cars in my household with this company and recommend them to everyone.” – Todd L. via BBB

Negative CNS Warranty Services Reviews

“We purchased a Volkswagen Passat with the Preferred Care Plus package. [We] maintained the car according to the manufacturer. The warranty company is refusing to cover repairs. The only real recourse is to file a lawsuit, which will likely cost more than the repairs are worth.” – Brian B. via BBB

“This is the biggest scam of all time. Two out of three claims have been denied. Even with it in writing that it’s covered, the company does not cover the policy for payment so the dealer does not do the work. Never again would I purchase something like this.” – Bill J. via BBB

CNA National Warranty Services: 3.4 Stars

CNA National Warranty does not make much information about its contracts available online. And because the company sells exclusively through dealerships, it is difficult to perform extensive cost research.

Based on what we were able to find, CNA National Warranty services seem like a worthwhile investment. The company offers a hefty range of coverage options and appears to have rates on the lower side of the industry average.

Be aware that, while we found no red flags regarding CNA National Warranty services, the company does not have a prominent customer service reputation. But that may be because it simply hasn’t spent effort on customer outreach.

Top Recommendations for Extended Car Warranties

CNA National Warranty services can only be purchased from select agents and dealerships. Depending on where you live, a CNA extended car warranty may not be available. 

Even if you are offered a contract from this company, it might not be the best option for your vehicle. Third-party extended warranty providers typically offer more flexible coverage and lower pricing than plans offered at dealerships. Read on to find out more about two of our top recommended providers: CarShield and Endurance.

CarShield: Best Value

CarShield sells six different extended warranty plans, the longest of which can cover vehicles up to 300,000 miles. The cost of a CarShield warranty will vary depending on your vehicle and mileage, but quotes we received from CarShield suggest it is among the lowest-cost providers.

The table below describes the terms we were offered when we reached out to CarShield while performing research for our in-depth CarShield review:

Vehicle CarShield Extended Warranty Plan Term Length Monthly Payment Down Payment Deductible
Ford Explorer Diamond Unlimited  $130 First payment $100
Dodge Caravan  Gold 4 years /
48,000 miles
for 18 months
$250 $100
Dodge Caravan Gold 4 years /
48,000 miles
for 24 months
$150 $100

We think CarShield is a good choice for high-mileage vehicles and powertrain coverage plans. Since opening in 2005, CarShield has paid over one billion in claims, and we found reviews from many satisfied customers on Trustpilot and Google.

Our research found this provider to be the most affordable. Plus, it offers monthly plans.

Endurance: Best Coverage

Endurance provides vehicle service contracts directly to consumers. Unlike contracts for CNA National Warranty services, Endurance contracts can be purchased directly from the provider. Endurance is accredited by the Vehicle Protection Association and is known for its reliable customer service.

Based on our extensive research into every major auto warranty provider, we find Endurance to have the most comprehensive coverage options. Endurance’s Supreme plan provides full bumper-to-bumper coverage with few exclusions.

All Endurance auto warranties include a free year of Endurance Elite Benefits, which gives drivers perks including total loss protection, key fob replacement, collision discount, tire repair or replacement, roadside assistance, and access to the Endurance mobile app.

Endurance is our pick for best direct provider with its comprehensive coverage options.
