description Risk assessment of automobile defect is classifying safety related risk level of manufacturing or designing defect. To carry out equivalent study between defect risk and failure defect, a risk flow route of automobile defect is developed introducing ETA method. A SPN function for risk assessment is setup based on Characteristics of automobile defect risk, and 3D matrix graph is introduced to describe overall risk. According to the scattered and fluctuant characteristics of automobile defect data, a risk forecast method based on gray theory is discussed. A risk assessment model of automobile defect is built; forecast of risk possibility is based on failure data. The model is corrected by residual discrimination. It is found that on gathering actual failure data from after-sales service, the gray model has a favorable applicability for forecast of risk possibility.
