NHTSA Defect Investigations for the 2004 Isuzu Ascender
The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2004 Isuzu Ascender, both ongoing and closed, are listed below:
INVESTIGATION: FUEL PUMP MODULE LEAKS GASOLINE
NHTSA Engineering Analysis #EA07009
Component(s): Fuel System, Gasoline:Delivery:Fuel Pump
Summary: During the course of this ea investigation, ODI observed that the majority of the complaints (88%) and warranty claims (94%) were reported for vehicles that are registered for use in the "salt belt" region of the us.this area includes 20 states in the northeast, mid atlantic and the midwest regions and the District of Columbia.consumers in the salt belt region reported to ODI that they could smell fuel vapors in their vehicles while driving.upon further examination of their vehicles, they discovered that fuel vapors were coming out of the top of the fuel tank. This condition is caused by corrosion of the return and sender lines of the fuel pump module.water and road salt collect on top of the fuel pump leading to small pinholes appearing on the fuel lines.fuel may leak and collect on top of the module and/or spill onto the ground.the data evaluated under this investigation reflect a relatively low frequency of occurrence that largely arises in salt belt states.GM has extended the warranty on the subject component to ten years or 120,000 miles.further use of Agency resources does not appear to be warranted at this time; accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.the Agency reserves the right to take further action if warranted by the circumstances.for additional information select document search.
