NHTSA investigation EA95029 is a Engineering Analysis opened on 1995-09-26 and currently closed. The subject of record is CHRYSLER CHRYSLER, which places this file inside the Office of Defects Investigation queue for CHRYSLER. Latest activity on this investigation was logged on 1996-11-13 - 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 EA95029 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: "AFTER AN EXTENSIVE INVESTIGATION AND ANALYSIS, CHRYSLER HAS IDENTIFIED THE DEFECT AS A FATIGUE FAILURE, ORIGINATION IN THE HEAT AFFECTED REGION OF THE "PROJECTION WELDS" OF THE STEERING WHEEL "HUB" TO STEERING WHEEL "ARM..." 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. Related CHRYSLER files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

AFTER AN EXTENSIVE INVESTIGATION AND ANALYSIS, CHRYSLER HAS IDENTIFIED THE DEFECT AS A FATIGUE FAILURE, ORIGINATION IN THE HEAT AFFECTED REGION OF THE "PROJECTION WELDS" OF THE STEERING WHEEL "HUB" TO STEERING WHEEL "ARMATURE" ATTACHMENT. THE HUB IS THE PORTION OF THE STEERING WHEEL ASSEMBLY THAT CONNECTS IT TO THE STEERING COLUMN SHAFT AND IS ATTACHED TO THE UNDERSIDE OF THE STEERING WHEEL ASSEMBLY BY 4 WELDS. IF CRACKS DEVELOP IN THE HEAT AFFECTED REGION OF THE WELDS AND PROPAGATE THROUGH THE STEERING WHEEL ARMATURE TO EACH OF THE WELDS, THE STEERING WHEEL CAN SEPARATE FROM THE HUB. THIS IS A SLOW PROGRESSIVE FAILURE WHICH NORMALLY OCCURS AT HIGH MILEAGE. IN SOME CASES COMPLAINANTS HAVE REPORTED A LOOSENESS OR WOBBLING OF THE STEERING WHEEL PRIOR TO SEPARATION. TO REMEDY THIS DEFECT, CHRYSLER WILL INSPECT THE STEERING WHEELS OF THE AFFECTED VEHICLES FOR CRACKS IN THE HUB AREA. IF ANY CRACKS ARE FOUND, THE STEERING WHEEL WILL BE REPLACED. ALL OTHER VEHICLES WILL HAVE REINFORCING PLATES INSTALLED WHICH WOULD PREVENT A STEERING WHEEL SEPARATION SHOULD CRACKING OCCUR.

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.
