try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
IN PERFORMING THIS ENGINEERING ANALYSIS, ODI DETERMINED THAT THE ELECTRIC POWER STEERING SYSTEM IN THE SUBJECT VEHICLES CAN MALFUNCTION OR FAIL, CAUSING THE DRIVER TO LOSE POWER STEERING ASSISTANCE; HOWEVER, DUE TO THE FOLLOWING REASONS, ODI HAS DECIDED THAT FURTHER EXPENDITURE OF AGENCY RESOURCES ON THIS INVESTIGATION IS NOT WARRANTED AT THIS TIME: - GM ISSUED CUSTOMER SATISFACTION CAMPAIGN (CSC) 04050A INDECEMBER 2004 TO ADDRESS THE ALLEGED DEFECT IN APPROXIMATELY58,700 SUBJECT VEHICLES, ENCOMPASSING AT LEAST 97 PERCENT OF THECOMPLAINT AND WARRANTY CLAIMS POPULATION.VEHICLES OUTSIDE THECSC 04050A POPULATION CONTAIN A NEWLY DESIGNED TORQUE ANDPOSITION SENSOR AND HAVE EXPERIENCED A RELATIVELY LOW COMPLAINTRATE.THIS CUSTOMER SATISFACTION CAMPAIGN PRESENTLY HAS ACOMPLETION RATE OF 52%. - THE IMPACT ON THE DRIVER?S ABILITY TO CONTROL THESE RELATIVELYSMALL AND LIGHT VEHICLES WAS LIMITED.VRTC TEST ENGINEERS WEREUNABLE TO INDUCE A FAILURE MODE THAT WOULD CAUSE THE EPS TOSUBSTANTIALLY LIMIT THE DRIVER?S ABILITY TO TURN THE VEHICLE IN APARTICULAR DIRECTION OR TO PROVIDE THE DRIVER WITH UNINTENDEDPOWER ASSISTANCE.- THERE IS NO RISK OF FIRE.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL CONTINUE TO MONITOR COMPLAINTS AND OTHER INFORMATION RELATING TO THE ALLEGED DEFECT IN THE SUBJECT VEHICLES AND TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED BY THE CIRCUMSTANCES.(FOR FURTHER DETAILS SEE ATTACHED ENGINEERING ANALYSIS (EA04-018)CLOSING REPORT.)
Vehicles and equipment listed for this investigation

Chevrolet
All Chevrolet recallsWhat an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
