Diamond Warranty is a Pennsylvania-based vehicle service contract provider founded in 2006. Operating through a nationwide network of dealerships, they offer several levels of protection designed to help drivers manage repair expenses after factory warranties expire. Their plans range from basic powertrain coverage to broader exclusionary contracts, with options for used vehicles, certified pre-owned models, and drivers seeking long-term protection.
Many contracts are backed by AmTrust Financial Services and may include benefits such as roadside assistance, rental car reimbursement, and trip interruption coverage. The company focuses on dealer-distributed service contracts rather than direct online sales, which means pricing and contract details often vary by vehicle and dealership. Diamond Warranty maintains an A+ rating from the Better Business Bureau, though they are not BBB accredited.
Customer feedback across review platforms is mixed, with experiences ranging from praise for responsive representatives and straightforward claims to complaints involving coverage disputes and communication challenges. With nearly two decades in the industry and a diverse selection of plans, the provider offers several features worth examining more closely before making a decision.
