NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Engineering Analysis EA05-022.

try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.

THE OFFICE OF DEFECTS INVESTIGATION (ODI) HAS CLOSED THE INVESTIGATION OF FRONT SEAT BELT BUCKLES IN MODEL YEAR 2002 JEEP LIBERTY VEHICLES.ON AUGUST 26, 2006, ODI OPENED PRELIMINARY EVALUATION (PE)05-046 TO INVESTIGATE COMPLAINT REPORTS THAT ALLEGED PROBLEMS WITH LATCHING AND UNLATCHING THE FRONT SEAT BELT BUCKLE.SEVERAL OF THE COMPLAINTS REPORTED THAT SOMETHING WAS BROKEN INSIDE OF THE BUCKLE.THE INVESTIGATION FOUND THAT SOME BUCKLES MAY EXPERIENCE FAILURE AND SEPARATION OF ONE, OR BOTH, OF THE INTERNAL LATCH GUIDE LEAF SPRINGS.LACK OF LEAF SPRING FUNCTION DOES NOT APPEAR TO INHIBIT BUCKLE OPERATION BECAUSE THERE IS ANOTHER SPRING THAT RETURNS THE RELEASE BUTTON.HOWEVER, A SEPARATED LEAF SPRING MAY IMPEDE THE MOTION OF THE BUCKLE RELEASE BUTTON IF IT BECOMES ENGAGED WITH MOVING PARTS.ANALYSIS OF THE AVAILABLE DATA SHOW THAT VEHICLES EXPERIENCING PROBLEMS WITH THE BUCKLES WERE EARLY PRODUCTION VEHICLES PRODUCED PRIMARILY IN CALENDAR YEAR (CY) 2001.

IN EARLY CY 2002, A CHANGE WAS MADE TO THE TOOLING USED TO PRODUCE THE BUCKLES. THIS CHANGE AFFECTED THE LEAF SPRINGS AND APPEARS TO HAVE HAD A POSITIVE EFFECT IN CORRECTING THE BUCKLE ISSUES THAT WERE EXPERIENCED IN THE EARLY PRODUCTION VEHICLES.THE COMPLAINT REPORT TREND IS DOWN AND THE FREQUENCY OF CONSUMER REPORTS IN CY 2006 HAS DECLINED TO THAT OF CY 2004.

Vehicles and equipment listed for this investigation

NHTSA's investigations file lists these vehicles and equipment for Engineering Analysis EA05-022. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. Model years with a try.vin recall page link to that page's NHTSA investigations section.

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.
