NHTSA Engineering Analysis EA87008 - closed, opened 1986-12-17.
NHTSA investigation EA87008 is a Engineering Analysis opened on 1986-12-17 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 1988-07-22 - 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 EA87008 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: "SUMMARY OF INFORMATION FROM MANUFACTURER: GM REVIEWED THE MATTER AND"...HAS NOT IDENTIFIED A SAFETY-RELATED BRAKE CONDITION THAT REQUIRESFIELD CORRECTION."ANALYSIS: IT APPEARS THAT THE PARKING BRAKE ACTUATION SYSTEM OR T..." 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.

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.
