MaxCare is an extended vehicle service contract introduced by CarMax in 2009, available exclusively at the time of purchasing a vehicle through their dealership network. Unlike many third-party warranty providers that offer multiple plan tiers, MaxCare uses a single exclusionary coverage model, similar to a factory bumper-to-bumper warranty, covering most mechanical and electrical components except for a defined list of exclusions. Contracts are tailored to each vehicle, with coverage typically extending up to 75,000 to 150,000 total odometer miles. While CarMax facilitates the customer experience, the plans are administered by third-party providers such as Fidelity Warranty Services and CNA National Warranty Corporation. Key benefits include 24/7 roadside assistance, rental car reimbursement, transferable coverage, and flexible payment options, including rolling the cost into monthly financing. A $50 deductible discount is also offered when using CarMax service centers or RepairPal-certified shops. Customer feedback is mixed, with many reporting strong coverage for major repairs, while others cite delays, strict claim requirements, and challenges when working with independent repair facilities.
