Chapter one1.1INTRODUCTIONFailure of automotive components is an occurrence common phenomenon in our real life. Components in a vehicle often operate under variance conditions such as high temperature, low temperature, high stress, high fatigue stress etc…Often the failure of a component results being careless to replacement of that part being required nevertheless, failure of some components can result out of the control vehicle and it is obvious to have a possibility of accidents and loss of life.
Off course, Service failures of such parts are associated with cost.Based on analysis of seventy automotive component failures of Fiat vehicles which has been received for investigation the distribution of component failure and the distribution of causes are given respectively.The most common component failure is that of the engine and that the most common cause of failure is abuse, however. The total contribution to the cause of failure could be the manufacturing or design errors and raw material defects.
Unlikely, Age is related failures as a manufacturing would be responsible for the failure of components. So it needs a continuous improvement on the part of the manufacturers. Finally, high proportion of failures due to failed repairs.
