| Investigations Summary: | This investigation was opened on Apr. 15, 2003. It was closed on Aug. 28, 2003. Kia has identified 22 non-crash engine compartment fires of any or unspecified cause on the subject vehicles. Nine fires (of which 4 were also reported to odi) are identified as being due to a fuel system leak originating between the firewall and the fuel injector rail (p/n 0k30e 13 150) in the passenger side area of the engine compartment. The remaining fires were due to varied or unknown causes. All 9 fires caused by a fuel system leak sustained severe and total damage. Analysis indicates that 1 fire was caused by a failed quick connect between the flexible high-pressure fuel supply line (p/n 0k32a 13 49xb) and the rigid line mounted to the firewall; 5 fires were caused by a failure of the flexible high-pressure fuel supply line itself or its related connectors; the remaining 3 fires were caused by unspecified fuel leaks in the vicinity of the fuel injector rail, flexible high-pressure fuel supply line, and the rigid line mounted to the firewall. Kia reports that neither the fuel injector rail nor the flexible high-pressure fuel supply line has been substantially modified since their introduction in the 2001 model year. This preliminary evaluation has been upgraded to an engineering analysis (ea03-015) so that odi may collect additional information and conduct further study of this issue. |
