NHTSA investigation EA08016 is a Engineering Analysis opened on 2008-08-21 and currently closed. The subject of record is HYUNDAI HYUNDAI, which places this file inside the Office of Defects Investigation queue for HYUNDAI. Latest activity on this investigation was logged on 2009-04-20 - 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 EA08016 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 APRIL 14, 2009, HYUNDAI-KIA AMERICA TECHNICAL CENTER, INC (HYUNDAI) NOTIFIED NHTSA THAT HYUNDAI IS CONDUCTING A SAFETY RECALL OF MODEL YEAR (MY) 1999 THROUGH 2004 HYUNDAI SONATA VEHICLES MANUFACTURED PR..." 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 HYUNDAI 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 APRIL 14, 2009, HYUNDAI-KIA AMERICA TECHNICAL CENTER, INC (HYUNDAI) NOTIFIED NHTSA THAT HYUNDAI IS CONDUCTING A SAFETY RECALL OF MODEL YEAR (MY) 1999 THROUGH 2004 HYUNDAI SONATA VEHICLES MANUFACTURED PRIOR TO NOVEMBER 20, 2003 THAT ARE REGISTERED AND OPERATED IN THE FOLLOWING "SALT BELT" STATES AND THE DISTRICT OF COLUMBIA: CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, AND WISCONSIN. HYUNDAI IS RECALLING THE VEHICLES TO REMEDY A CONDITION WHERE INTERNAL CORROSION OF THE FRONT SUBFRAME MAY LEAD TO SEPARATION OF THE LOWER CONTROL ARM AT THE FORWARD MOUNTING POINT AND/OR SEPARATION OF THE AXLE FROM THE TRANSAXLE. THIS COULD RESULT IN A LOSS OF VEHICLE CONTROL AND/OR VEHICLE DISABLEMENT. THE SUBFRAMES WILL BE INSPECTED IN THE RECALLED VEHICLES USING A PROCEDURE DEVELOPED BY HYUNDAI TO MEASURE METAL THICKNESS. PARTS WITH PERFORATIONS FROM CORROSION OR WITH METAL BELOW THE SPECIFIED THICKNESS WILL BE REPLACED WITH REDESIGNED SUBFRAMES. IF THE MINIMUM METAL THICKNESS IS MET, DRAINAGE HOLES AND RUST PROOFING MATERIAL WILL BE ADDED TO THE EXISTING SUBFRAME. ODI'S ANALYSIS OF COMPLAINT DATA REVEALED THAT 98% OF THE CONSUMER COMPLAINTS WERE FROM VEHICLES EITHER ORIGINALLY SOLD OR OPERATED IN SALTBELT STATES. SIMILARLY 99.7% OF THE WARRANTY CLAIMS WERE FROM VEHICLES ORIGINALLY SOLD OR OPERATED IN SALTBELT STATES. ODI IDENTIFIED 105 REPORTS OF LOWER CONTROL ARM DETACHMENT AND/OR AXLE SEPARATION FROM THE TRANSAXLE THROUGH ANALYSIS OF WARRANTY AND COMPLAINT INFORMATION AND CONSUMER INTERVIEWS. ONE HUNDRED THREE (103) OF THE 105 INCIDENTS INVOLVED VEHICLES IN STATES COVERED BY THE RECALL. IN ADDITION TO THE SUBJECT VEHICLES, HYUNDAI ALSO NOTED IN THE APRIL 14, 2009 LETTER THAT MY 2001 THROUGH 2004 XG300 AND XG350 WERE ALSO BEING RECALLED AS THEY WERE MANUFACTURED WITH SUBFRAMES SIMILAR IN DESIGN THE SUBJECT

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.
