NHTSA Defect Investigations for the 1997 Cadillac DeVille

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 1997 Cadillac DeVille, both ongoing and closed, are listed below:


    NHTSA Engineering Analysis #EA00004

    Component(s): Air Bags:Side/Window

    Summary: There is no summary currently available


    NHTSA Preliminary Evaluation #PE98005

    • Status:
    • Date Opened: February 06, 1998
    • Date Closed: August 27, 1998
    • Recall: No recall issued

    Component(s): Exterior Lighting



    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.


    NHTSA Defect Investigation #RQ03001

    • Status:
    • Date Opened: January 02, 2003
    • Date Closed: September 15, 2003
    • Recall: No recall issued

    Component(s): Steering
    Steering:Rack And Pinion

    Summary: GM conducted a safety recall (NHTSA # 02V286) to address a steering defect pertaining to a lower pinion bearing (lpb) within the rack and pinion steering gear (R&P). The recall covered 1,159,156 model year 1997-1998 Pontiac Grand Prix vehicles built between March 1, 1996 and October 31, 1997, 1996-1998 Pontiac trans sport, Chevrolet lumina apv, Chevrolet Venture, Oldsmobile Silhouette minivans, and Chevrolet cavalier and Pontiac sunfire sedans built between January 1, 1996 and October 31, 1997.ODI opened this rq after receiving reports that other vehicles were exhibiting the same symptoms as the recalled vehicles.based on ODI's review of technical and complaint data collected during the rq, the w-cars are associated with either a higher steering complaint rate or a higher lpb failure rate than the other vehicles investigated under the rq and are above or near the rates for the recalled vehicles.thus, ODI will further examine the w-cars (1996-1997 Oldsmobile cutlass supreme, 1996-1998 Buick regal, Chevrolet lumina, Chevrolet Monte Carlo, 1997-1998 Buick century, and 1998 Oldsmobile intrigue) under a new investigation, engineering analysis (ea)03-019.
