NHTSA investigation EA11013 is a Engineering Analysis opened on 2011-09-15 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 2012-03-14 - 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 EA11013 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: "In a letter dated March 2, 2012 Chrysler Group LLC (Chrysler) submitted a Defect Information Report (NHTSA recall No. 12V-085) to the NHTSA identifying a safety defect regarding rear suspension lower control arm corrosio..." 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

In a letter dated March 2, 2012 Chrysler Group LLC (Chrysler) submitted a Defect Information Report (NHTSA recall No. 12V-085) to the NHTSA identifying a safety defect regarding rear suspension lower control arm corrosion in approximately 210,000 model year (MY) 2004 and 2005 Jeep Liberty vehicles, originally sold or currently registered in a Salt-belt state (Connecticut, Delaware, Iowa, Illinois, Indiana, Kentucky, Massachusetts, Maine, Maryland, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia). According to Chrysler, excessive corrosion could result in fracture of a rear suspension lower control arm which may result in a loss vehicle control. In analysis of both Vehicle Owner Questionnaire (VOQ) data submitted to the Office of Defects Investigation (ODI) and consumer complaint data submitted to Chrysler, ODI identified 54 non-duplicative reports alleging failure of one or both rear lower control arms due to excessive corrosion. Thirteen of these complaints allege that the failure resulted in some loss of vehicle control. For purposes of this analysis, loss of control events involve alleged complete or partial departure from the intended lane of travel. An additional 11 complaints reported difficulty maintaining control of the vehicle when the rear lower control arm failed. All of the complainant vehicles were either originally sold or registered at the time of the incident in a Salt-belt state. ODI did not identify any reports (complaints or warranty claims) related to rear lower control failure due to excessive corrosion in the approximately 138,000 MY 2004 and 2005 Liberty vehicles that are not included in this recall (i.e., not sold or currently registered in a Salt-belt state). In Chrysler’s Defect Information Report, Chrysler stated that during the investigation a field survey of MY 2004 and 2005 Jeep Liberty vehicles was conducted. In total, C

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.
