NHTSA Preliminary Evaluation PE03001 - closed, opened 2003-01-03.
NHTSA investigation PE03001 is a Preliminary Evaluation opened on 2003-01-03 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 2003-05-06 - 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 PE03001 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: "OF THE 697 TOTAL COMPLAINTS, 240 WERE RECEIVED FOR THE ENVOY AND 457 FOR THE BRAVADA. GM HAS IDENTIFIED ABOUT 5,000 WARRANTY CLAIMS RELATED TO STALLING IN THE SUBJECT VEHICLES. GM REPORTS THAT A TRANSIENT VOLTAGE SPIKE G..." 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
OF THE 697 TOTAL COMPLAINTS, 240 WERE RECEIVED FOR THE ENVOY AND 457 FOR THE BRAVADA. GM HAS IDENTIFIED ABOUT 5,000 WARRANTY CLAIMS RELATED TO STALLING IN THE SUBJECT VEHICLES. GM REPORTS THAT A TRANSIENT VOLTAGE SPIKE GENERATED IN THE ECAS DEGRADES THE PERFORMANCE OF THE PCM RESULTING IN ENGINE STALL. GM MODIFIED THE ECAS WIRING BUNDLE AND THE PCM FOR VEHICLES BUILT AFTER DECEMBER 6, 2001 TO ADDRESS THE STALLING PROBLEM.
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.
