NHTSA Engineering Analysis EA99004 - closed, opened 1999-01-15.
NHTSA investigation EA99004 is a Engineering Analysis opened on 1999-01-15 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 2000-04-18 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
An Engineering Analysis like EA99004 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.
Investigators summarized the matter as follows: "BASED ON THE RELATIVELY LOW FAILURE FREQUENCY MEASURED OVER AN EXTENDED EXPOSURE TIME AND THE FACT THAT THE GREAT MAJOITY OF INCIDENTS ARE CONFINED WITHIN THE BLOWER HOUSING, A SAFETY-RELATED DEFECT TREND HAS NOT BEEN ID..." 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
BASED ON THE RELATIVELY LOW FAILURE FREQUENCY MEASURED OVER AN EXTENDED EXPOSURE TIME AND THE FACT THAT THE GREAT MAJOITY OF INCIDENTS ARE CONFINED WITHIN THE BLOWER HOUSING, A SAFETY-RELATED DEFECT TREND HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF THE AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED. 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 FURTHE ACTION IF WARRANTED BY THE CIRCUMSTANCES.
About This Investigation Type
An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
