A comprehensive warranty is a type of warranty that covers a wide range of potential issues or defects for a product or service. Unlike basic or limited warranties, which might only cover specific parts or problems, a comprehensive warranty typically includes protection for most, if not all, components and potential failures. This kind of warranty often includes both parts and labor, meaning if something goes wrong with the product or service during the warranty period, the manufacturer or provider will repair or replace it without additional cost to the customer.
