NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE03-050.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
THE FUEL RAIL ASSEMBLIES USED IN THE SUBJECT VEHICLES WERE MANUFACTURED BY DANA.THE FUEL RAIL JUMPER TUBES WERE MADE OF MONOLAYER NYLON 12 (PA12).
IN MODEL YEAR (MY) 1998, THE JUMPER TUBE MATERIAL WAS CHANGED FROM PA12 TO M-BOND (A MULTI-LAYER PTFE/PA12).
IN ADDITION, ALL SERVICE PARTS PRODUCED SINCE THE END OF PRODUCTION 1997 USE THE M-BOND JUMPER TUBES. MATERIAL ANALYSIS PERFORMED BY DANA ON FAILED FUEL RAILS SHOWED THAT THE MONO-LAYER NYLON 12 JUMPER TUBES ARE SUSCEPTIBLE TO ENVIRONMENTAL STRESS CRACKING (ESC).
GM BELIEVES THE ESC IS A RESULT OF HEAT, TIME, ALCOHOL BLENDED FUEL, FUEL PRESSURE CYCLING, AND DESIGNED IN STRESS. EIGHT OF THE GM COMPLAINTS ARE DUPLICATIVE OF ODI COMPLAINTS.ODI HAS RECEIVED 77 OF IT'S 123 COMPLAINTS IN THE PAST 12 MONTHS.FUEL RAIL PART SALES OVER THE LAST THREE YEARS RANGE FROM 3.0 PERCENT OF PRODUCTION FOR THE MY 1997 CADILLAC VEHICLES TO 13.1 PERCENT FOR THE MY 1995 AURORAS.AT LEAST ONE OF THE FIRE INCIDENTS OCCURED WHILE THE VEHICLE WAS PARKED WITHIN A GARAGE ATTACHED TO THE CONSUMERS HOME.THE FIRE RESULTED IN DAMAGE TO THE DWELLING AS WELL AS THE TOTAL LOSS OF THE VEHICLE.THIS INVESTIGATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS.
Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Preliminary Evaluation PE03-050. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. Model years with a try.vin recall page link to that page's NHTSA investigations section.
What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
