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.
