Abstract:

Automobile steering system defects affect the automobile safety, and are important causes of
automobile-recall. Risk assessment guidelines were proposed for automobile steering system defects to improve
the manage efficiency of automobile recall, based on risk matrix and risk level after analyzed automobile
steering system failure forms and their influence. Automobile recall cases caused by steering system defects
were analyzed using the risk assessment guidelines. The results show that the defect risk matrix method can
identify steering system defects and evaluate the risk level. Therefore, the defect risk assessment guidelines can
assess the automobile steering system defects risk and automobile recall, also can be extended to other defects
of automobile, and enhance the process of automobile recall.

Key words: automobile safety, steering system, automobile recall, risk assessment, risk matrix
