ANALYSIS OF ON-ROAD FAILURE DATA

A statistical analysis of 2300 On-Road-Failure survey responses to define the vehicle systems most frequently responsible for on-road breakdowns of passenger vehicles was conducted. It was found that the fuel system, cooling system, ignition system, starting/charging system and engine were responsible for 84% of the reported on-road failures. Significant differences in system failure distributions between vehicle make/models were also identified.
