The different types of warranty policy have been established in order to fulfill the demand of manufacturers and the requirement of buyers so that a win-win situation could be acquired. However, when considering these warranty policies, an important concept to keep in mind is warranty reclaims. Warranty reclaims extend the scope of warranty activities beyond the walls of a single company to encompass suppliers, manufacturers, OEMs, distributors, dealers, repair centers, policy carriers, and customers. The present work is designed for a novel method to solve the nonlinear warranty reclaims in the form of diffusion equations. The main motivation for this work is that the warranty reclaims can be represented as the diffusion equations, and the diffusion equation is a partial differential equation which describes density dynamics in a material undergoing diffusion. The diffusion equation is also used to describe processes exhibiting diffusive-like behavior such as warranty reclaims. The approximate solution of this problem is calculated in the form of finite differences with easily computable terms. To represent the capability and reliability of the method, some automobile warranty cases have been illustrated.
