considered very difficult to find out and to diagnose. The increase in system robustness against such sporadic
failures which affect exhaust gas emissions, engine performance and reliability are fundamental to attain
engine and vehicle reliability. A methodology based on risk and reliability analysis concepts is presented to
identify the root cause of such sporadic failures. The sporadic failures to be analyzed are selected based on
warranty reports database considering the criticality of failure consequences. The method is applied to
evaluate sporadic failures of a sub-compact vehicle platform commercialized in Brazil. The method allows
identifying manufacturing and assembly processes of electro-electronic devices that are main causes of some
sporadic failures.
