CNA National is a provider of extended auto warranties with over 30 years of experience in the industry. They offer a wide range of coverage options to fit your needs, including bumper-to-bumper coverage, powertrain coverage, and roadside assistance. You can purchase their extended auto warranty from your local dealership. CNA National is also a 26-time Dealers' Choice Award winner, which is a testament to their high level of customer service. Numerous levels of coverage are available for CNA National Warranty Services to meet individual needs. Roadside assistance, rental car reimbursement, travel and hotel reimbursement, Limp-along support, and wheel protection are all included in certain plans of their policies. Furthermore, they offer coverage for several types of automobiles, ensuring that their services are accessible to various clients.
SilverRock is a vehicle service contract administrator founded in 2014 and headquartered in Phoenix, Arizona. Rather than selling extended auto warranties directly to consumers, they administer protection plans for vehicles purchased through retailers such as Carvana and DriveTime. Depending on the contract, customers may receive a limited warranty, an optional vehicle service contract, or both, with coverage for many major mechanical and electrical systems. Many plans also include benefits such as roadside assistance, rental reimbursement, transferable coverage, and access to a nationwide network of participating repair facilities.
One feature that distinguishes SilverRock is their close integration with the vehicle buying process. Eligible customers can often add protection when purchasing a vehicle, and participating repair shops can work directly with SilverRock during the claims process. Pricing and contract terms vary based on the retailer, vehicle, and selected coverage, so there is no standard published price.
Customer feedback is mixed across major review platforms. While some policyholders report smooth claims and substantial savings on expensive repairs, others describe claim disputes, communication issues, and inconsistent service experiences. This review takes a closer look at SilverRock's coverage options, contract terms, costs, customer experience, support resources, and overall value to help determine whether their vehicle protection plans are worth considering.
