REAR AXLE TRAILING ARM FAILURE
NHTSA Engineering Analysis EA03005 - closed, opened 2003-04-23.
NHTSA investigation EA03005 is a Engineering Analysis opened on 2003-04-23 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 2004-01-12 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
An Engineering Analysis like EA03005 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.
Investigators summarized the matter as follows: "ON NOVEMBER 18, 2002, ODI OPENED A PRELIMINARY EVALUATION (PE02-086) TO EVALUATE ALLEGATIONS OF REAR AXLE TRAILING ARM FAILURES IN THE SUBJECT VEHICLES (U-VAN) WHICH INCLUDED TWO REPORTING CRASHES. ON APRIL 9, 2003, ODI..." 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
ON NOVEMBER 18, 2002, ODI OPENED A PRELIMINARY EVALUATION (PE02-086) TO EVALUATE ALLEGATIONS OF REAR AXLE TRAILING ARM FAILURES IN THE SUBJECT VEHICLES (U-VAN) WHICH INCLUDED TWO REPORTING CRASHES. ON APRIL 9, 2003, ODI UPGRADED PE02-086 TO AN ENGINEERING ANALYSIS (EA03-005) TO CONTINUE ITS EXAMINATION OF THE ISSUE. THE TRAILING ARM DESIGN IN THESE VEHICLES HAS BEEN USED IN THE U-VAN FROM MY 1997 THROUGH THE PRESENT. THE GM ANALYSIS CONCLUDED THAT THE SUBJECT TRAILING ARMS COULD CRACK OR BUCKLE IF THEY WERE DAMAGED DURING ASSEMBLY, PRE-DELIVERY HANDLING, OR SUBJECTED TO CERTAIN SERVICE RELATED ABUSE CONDITIONS SUCH AS IMPROPER TOWING OR JACKING. ANALYSIS OF ODI AND GM DATA HAS IDENTIFIED 19 INCIDENTS OF REAR AXLE TRAILING ARM FAILURES IN THE SUBJECT VEHICLES. THERE HAVE BEEN NO NEW REPORTS TO ODI OR GM IN THE LAST 12 MONTHS AND ONLY ONE NEW COMPLAINT IN THE LAST 21 MONTHS. DUE TO THE LOW COMPLAINT RATE AND THE ABSENCE OF A CONTINUING TREND IN REPORTED FAILURES, A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED. 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 TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES. FOR ADDITIONAL INFORMATION, SEE THE ATTACHED CLOSING REPORT.
About This Investigation Type
An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
