NHTSA Defect Investigations for the 1996 Cadillac Eldorado

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 1996 Cadillac Eldorado, both ongoing and closed, are listed below:


    NHTSA Engineering Analysis #EA98004

    Component(s): Air Bags

    Summary: There is no summary currently available


    NHTSA Engineering Analysis #EA04003

    Component(s): Fuel System, Gasoline
    Fuel System, Gasoline:Delivery
    Fuel System, Gasoline:Fuel Injection System:Fuel Rail

    Summary: On March 3, 2004, General Motors notified ODI that it was recalling approximately 94,000 MY 1995-97 Oldsmobile Aurora vehicles equipped with 4.0L V8 engines (RPO L47 - vin8 "C") to address concerns with underhood fuel leakage from cracked fuel rails and, in some of the vehicles, cracked fuel return lines. According to GM, the nylon tubing (PA12) used in the fuel rail construction in these vehicles may degrade and crack.GM's supplier attributed the cracking to the combined effects of heat, time, alcohol fuel, fuel pressure cycling, and design stresses.in addition, GM stated that the MY 1995 Aurora uses a unique underhood fuel return line that may also crack at unusually high rates.GM dealers will install a new fuel rail constructed out of stainless steel in all of the recalled vehicles and will also install a revised chassis fuel return line in the MY 1995 Aurora. On April 16, 2004, General Motors notified ODI that it was adding approximately 389,000 MY 1995-97 Cadillac Seville, Deville and Eldorado vehicles equipped with 4.6L V8 engines (RPO's LD8 and L37 - vin8 "Y" and "9") to recall 04V-110.the recalled Cadillac will receive the new stainless steel fuel rails.this engineering analysis is closed.


    NHTSA Preliminary Evaluation #PE03050

    • Status:
    • Date Opened: October 30, 2003
    • Date Closed: February 03, 2004
    • Recall: No recall issued

    Component(s): Fuel System, Gasoline:Fuel Injection System:Fuel Rail

    Summary: 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 Aurora.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.
