What Is Diamond Warranty Corp.?

Headquartered in Wilkes-Barre, Pennsylvania, Diamond Warranty Corp. specializes in vehicle service contracts (VSC) and ancillary products. Their main goal is to assist finance and insurance (F&I) departments in dealerships by providing cost-effective and dependable solutions to customers. With a range of extended vehicle warranty plans, they promise comprehensive protection catered to different vehicle types and budgets for your peace of mind.

Key Features & Benefits

When considering a VSC provider, it's important to evaluate various factors to determine the best option for your specific needs. Diamond Warranty Corp. offers many perks designed to ensure customer satisfaction. Some of the benefits are as follows:

Flexible contract duration

Unlike other providers that offer rigid fixed-term contracts, DWC understands that customer needs vary significantly. As a result, they have designed plans with flexible contract durations, allowing you to choose the coverage that best suits your unique situation. Whether you need short-term protection for three months to supplement your newer car or an extended warranty for an older car, DWC makes sure that their contracts are tailored, providing cost-effective solutions for different needs.

24/7 roadside assistance

The company offers a 24/7 roadside assistance program for most of their programs that provides a range of services in case of emergencies, including towing services, a rental car program, fuel delivery, and trip interruption.

Transferable coverage

In certain situations, customers have the option to transfer the remaining coverage to the new owner if they decide to sell their vehicle before the contract period expires. This transferability enhances the vehicle's resale value, providing added security for potential buyers. However, customers should review the terms and fees associated with the transfer before initiating the process.

Drawbacks to Consider

While the advantages may be appealing, it’s important to consider potential drawbacks related to their services to make well-informed decisions. Here are a few things to keep in mind:

Limited coverage conditions

DWC imposes age and mileage limits on their contract services, providing coverage for vehicles up to 15 years old or 125,000 miles. This coverage limit is comparatively lower than that of competitors in the market.

Limited nationwide accessibility

The availability of coverage may not extend to all parts of the United States, which can have a few effects. Residents in rural or remote areas may experience longer travel times and additional costs due to the scarcity of nearby authorized service centers. Moreover, customers who frequently travel or relocate may encounter difficulties outside the covered areas.

Limited information online

The corporation's website provides some information regarding their coverage, claims, and plans. However, little to no information is available regarding deductibles, cancellation fees, and the terms and conditions associated with transferability. The website also does not provide the locations of their authorized repair shops, which provide the mechanical repair coverage you might need later down the line. 

Limited to dealerships

To ensure a smooth experience with Diamond Warranty, it's important for customers to be aware that they must contact an affiliate dealership for any inquiries regarding initiating, canceling, authorizing repairs, or renewing their warranty. However, it's important to keep in mind that filing a claim should be done through an authorized repair shop or mechanic.

Diamond Warranty Coverage Plans

Diamond Warranty Corp. offers five vehicle protection plans, each providing varying levels of coverage:

Powertrain: Offers basic coverage for essential powertrain components, such as the drivetrain, gaskets, engine, and transmission. The plan ranges from 3 months to 12 months with unlimited mileage.

Powertrain Plus: The enhanced Powertrain coverage goes beyond the basics, encompassing additional components like the engine, rear axle assembly, and OEM single and twin-turbo/superchargers.

Plus: An independent coverage option that adds features beyond the Powertrain Plus plan, including steering and suspension, air conditioning, fuel systems, electrical components, and towing services. The plan ranges from three months and 5,000 miles to 48 months and 50,000 miles.

Enhanced: Builds upon the previous options by offering higher-level protection for a broader range of parts and systems, including sensors, heating systems, steering, and brakes.

Exclusionary (Factory Wrap): The most extensive coverage plan, similar to a manufacturer's warranty for new cars, covers most components and systems of the vehicle except for a few specified in the contract. It provides covered repairs and protection for up to five years/100,000 miles.

The pricing for these plans can be found on their website, specifically on their FAQ page.

Is It the Right Choice for You?

If you're thinking about getting an extended car warranty, Diamond Warranty Corp. could be a suitable choice if you value comprehensive roadside assistance or temporary coverage for your powertrain components. However, if you're in need of a more extensive bumper-to-bumper option, it might be worth exploring other warranty companies.

Customer Reviews

While you might be tempted to consider using Diamond’s services, it is important to carefully consider the available reviews before making a decision. Although they have an A+ rating with the BBB (Better Business Bureau), it is important to note that they are not BBB-accredited, and their average rating is 1 out of 5 stars. On Trustpilot, however, they have 170 reviews, with an average rating of 1.7 out of 5 stars.

The Trustpilot customer reviews touch on different recurring themes in their experiences, such as dissatisfaction with the claims process, service delays, unresponsive customer service, and challenges in finding authorized repair shops.

On the BBB, similar complaints have been raised, with the majority of customers highlighting a lack of response and delays in receiving refunds. Moreover, some dealerships have reported difficulties reaching the company after completing the necessary repairs, resulting in unpaid claims. One particular review mentioned the inconvenience a customer experienced when they couldn't get their car back due to unpaid claims, forcing them to rent a car for their daily commute to work.

While the positive reviews are few and far between, the majority of them praise the professionalism and helpfulness of some customer care representatives.

While it's crucial to acknowledge the validity of negative reviews, it's equally important to take them with a grain of salt. This is because customers often tend to share negative experiences more readily than positive ones.

How Can You Contact Diamond Warranty Corp.?

You can reach the company’s customer service through their general phone number (1-800-384-5023) or 24-hour roadside assistance number (1-855-278-4690). Correspondence can also be made through email addresses or postal mail, as listed on their website. Or you can reach them through any partnered dealership near you.

Final thoughts

If you are thinking about getting vehicle protection from Diamond Warranty Corp., you should look into what they have to offer as well as any limitations. On the positive side, they provide authorized service centers in 30 states, transferable coverage, and 24/7 roadside assistance. However, it's worth noting that their services have specific mileage and vehicle age requirements, and availability may vary by state.

Furthermore, some details about some of their services, such as deductibles, cancellation fees, the terms and conditions associated with transferability, and the locations of repair shops and authorized dealerships are limited. To contact them directly or handle any processes related to the initiation, cancellation, authorization of repairs, or renewal of your warranty, you'll need to visit a partnered dealership.
