NHTSA Defect Investigations for the 1998 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 1998 Cadillac DeVille, both ongoing and closed, are listed below:

  1. INVESTIGATION: INADVERTENT OF SIDE IMPACT AIR BAG

    NHTSA Engineering Analysis #EA00004

    Component(s): Air Bags:Side/Window

    Summary: There is no summary currently available

  2. INVESTIGATION: INADVERTENT DEPLOYMENT OF SIDE AIR BAG

    NHTSA Preliminary Evaluation #PE99061

    • Status:
      CLOSED
    • Date Opened: September 27, 1999
    • Date Closed: February 15, 2000
    • Recall: No recall issued

    Component(s): Air Bags:Side/Window

    Summary: This side impact air bag can inadvertently deploy due to a number of root caused including: Erroneous acceleration inputs or false activation of the air bag deployment algorithm due to an electrical malfunction in the sensing and diagnostic module (SDM); false activation resulting from an electrical short in the SDM wiring harness; and false acceleration inputs resulting from improper SDM installation.in each case, it is possible for the inadvertent deployment to occur without warning.the scope of the engineering analysis is expanded to include MY 1997 Deville vehicles.ODI has identified 253 reports alleging inadvertent deployment of a side impact air bag on 1997-1999 Cadillac Deville vehicles.GM has made 8 modifications in the manufacturing or design of the side impact system in the subject vehicles some of which are focused on reducing the potential for an electrical short.inadvertent deployment of a side impact air bag can result in unwarranted injuries to occupants and presents the potential for loss of vehicle contol. An engineering analysis is warranted to determine if a potential safety defect exists.

  3. INVESTIGATION: POWER RACK AND PINION STEERING FAILURE

    NHTSA Defect Investigation #RQ03001

    • Status:
      CLOSED
    • 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.
