INADVERTENT DEPLOYMENT OF SIDE AIR BAG
NHTSA Preliminary Evaluation PE99061 - closed, opened 1999-09-27.
NHTSA investigation PE99061 is a Preliminary Evaluation opened on 1999-09-27 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 2000-02-15 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Preliminary Evaluation like PE99061 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.
Investigators summarized the matter as follows: "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 SE..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time.
Investigation 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.
About This Investigation Type
A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
