BRAD LAMB OF THE NORTH CAROLINA CONSUMERS COUNCIL, REQUESTING INVESTIGATION OF AN ALLEGED DEFECT EVIDENCED BY SHAKE OR BOUNCE OF THE HEADLAMPS ON MODEL YEAR 2004 PONTIAC GRAND PRIX VEHICLES.ODI'S PREVIOUS REVIEW OF THIS ISSUE IN OCTOBER 2003, DETERMINED THAT IT DID NOT WARRANT INVESTIGATION.ODI'S CURRENT ANALYSIS IDENTIFIED 36 COMPLAINTS IN THE CONSUMER COMPLAINT DATABASE; AND A DECLINING TREND OF REPORTS WAS EVIDENT.A FEW FIELD REPORTS OF SIMILAR NATURE WERE ALSO SUBMITTED BY THE MANUFACTURER IN ITS EARLY WARNING REPORTING DATA.A SERVICE BULLETIN AND A REVISED HEADLAMP RETAINING BRACKET WERE ISSUED IN NOVEMBER 2004, AND THESE ACTIONS ARE SEEN AS APPROPRIATE IN ADDRESSING THE PROBLEM WHILE ALL OF THE SUBJECT VEHICLES ARE STILL COVERED BY THE NEW VEHICLE WARRANTY.COMPROMISE TO SAFE VEHICLE OPERATION AS A RESULT OF THIS ISSUE WAS NOT IDENTIFIED.IT IS UNLIKELY THAT INVESTIGATION WOULD RESULT IN A NHTSA ORDER FOR THE RECALL AND REMEDY OF THIS PROBLEM.

What 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.
