ON APRIL 14, 2009, HYUNDAI MOTOR CORPORATION SUBMITTED TO ODI A DEFECT INFORMATION REPORT INDICATING THAT IT WOULD RECALL A SALT-BELT POPULATION OF APPROXIMATELY 155,317 MODEL YEAR (MY) 2001 THROUGH 2003 HYUNDAI ELANTRA VEHICLES TO REMEDY A DEFECT THAT CAN RESULT IN LOSS OF VEHICLE CONTROL WITH AN INCREASED RISK OF A CRASH WHILE DRIVING (09V-125).THE AFFECTED VEHICLES COVER ALL MY 2001, MY 2002, AND MY 2003 THROUGH JANUARY 13, 2003 PRODUCTION.THESE INCLUDE ELANTRA VEHICLES THAT WERE ORIGINALLY SOLD OR CURRENTLY REGISTERED IN CONNECTICUT, DELAWARE, DISTRICT OF COLUMBIA, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA AND WISCONSIN.THE TOTAL THREE-YEAR PRODUCTION POPULATION FOR THE ELANTRA VEHICLES IS APPROXIMATELY 350,000. ACCORDING TO HYUNDAI, ROAD SALT CAN COLLECT IN THE OUTBOARD PORTION OF THE FRONT LOWER CONTROL ARM AND MAY RESULT IN INTERNAL CORROSION LEADING TO THINNING OF THE STEEL IN THE LOWER CONTROL ARMS.THE CORROSION MAY PROGRESS TO THE POINT WHERE THE LOWER CONTROL ARM UPPER AND LOWER PANELS BECOME PERFORATED.A PERFORATED FRONT LOWER CONTROL ARM MAY FRACTURE BETWEEN ITS BALL JOINT ATTACHMENT AND THE FORWARD AND REARWARD PIVOT ATTACHMENTS TO THE CHASSIS.THIS COULD AFFECT THE DRIVER'S CONTROL OVER THE TIRE AND WHEEL ASSEMBLY.HYUNDAI'S RECALL PROCEDURE INSTRUCTS DEALERS TO MEASURE THE THICKNESS OF THE STEEL IN THE FRONT LOWER CONTROL ARMS.IF SPECIFIED LEVELS OF CORROSION DAMAGE HAVE OCCURRED, THE FRONT LOWER CONTROL ARMS WILL BE REPLACED WITH NEW FRONT LOWER CONTROL ARMS WITH ADDITIONAL HOLES IN THE UPPER AND LOWER PANELS. ODI'S ANALYSIS OF FRONT LOWER CONTROL ARM COMPLAINT AND WARRANTY DATA SHOWS 220 COMPLAINTS AND 1,033 WARRANTY CLAIMS FOR THE TOTAL APPROXIMATELY 350,000 SUBJECT VEHICLES SOLD THROUGHOUT THE UNITED STATES, RESULTING IN A COMPLAINT RATE OF 62.82 PER 100,000 VEHICLES AND A CLAIM RATE OF 0.3 PERCENT.ODI'S ANALYSIS FOUND 7 COMPLAINTS AND 90 WARRANTY CLAIMS IN 132,475 VEHICLES SOLD IN NON-SALT BELT STATES, RESULTING IN A COMPLAINT RATE OF 5.3 PER 100,000 VEHICLES AND A CLAIM RATE OF 0.1 PERCENT.

THIS PRELIMINARY EVALUATION IS CLOSED.
