NHTSA investigation PE96001 is a Preliminary Evaluation opened on 1996-01-04 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 1996-05-31 - 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 PE96001 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: "INFORMATION OBTAINED FROM GM INDICATES THAT FURTHER INVESTIGATION TO DETERMINE THE CAUSE OF WHEEL SEPARATIONS IS WARRANTED. IN GM'S RESPONSE DATED APRIL 26, 1996, GM STATED THAT: "GM HAS NOT IDENTIFIED ANY DEFECT IN THE..." 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
INFORMATION OBTAINED FROM GM INDICATES THAT FURTHER INVESTIGATION TO DETERMINE THE CAUSE OF WHEEL SEPARATIONS IS WARRANTED. IN GM'S RESPONSE DATED APRIL 26, 1996, GM STATED THAT: "GM HAS NOT IDENTIFIED ANY DEFECT IN THE MANUFACTURE OF THE SUBJECT VEHICLES WHIH MAY CONTRIBUTE TO WHEEL SEPARATION.

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.
