Affected Component: FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY

Summary

SOME 2003-2004 MODEL YEAR ISUZU ASCENDER VEHICLES CONTAIN A FUEL TANK INLET CHECK VALVE (ICV) THAT COULD FRACTURE. THE ICV IS LOCATED ABOVE THE FULL FUEL LEVEL. A FRACTURED ICV COULD ALLOW FUEL VAPORS TO PASS THROUGH AND DROPLETS OF FUEL TO ACCUMULATE ON THE SIDE OF THE FUEL TANK AS IT PASSES OVER THE FRACTURE DURING REFUELING. IF THE ICV FRACTURES, THE VEHICLEÂ’S SERVICE ENGINE SOON (SES) LIGHT MAY ILLUMINATE, AND THE OWNER MAY NOTICE A FUEL ODOR AND/OR A FEW DROPS OF FUEL ON THE GROUND WHEN REFUELING THE VEHICLE. THIS SPECIAL COVERAGE COVERS THE CONDITION DESCRIBED FOR A PERIOD OF 15 YEARS OR 150,000 MILES WHICHEVER OCCURS FIRST, FROM THE DATE THE VEHICLE WAS ORIGINALLY PLACED IN SERVICE, REGARDLESS OF OWNERSHIP.
