Defect

HYUNDAI IS RECALLING 188,282 MY 2001-2004 SONATA AND MY 2001-2004 XG300 AND XG350 VEHICLES ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN, AND THE DISTRICT OF COLUMBIA. ROAD SALT APPLIED IN THESE JURISDICTIONS DURING THE WINTER MONTHS MAY RESULT IN PROGRESSIVE, INTERNAL CORROSION OF THE FRONT SUB-FRAME ON THE VEHICLES, AND MAY RESULT IN THINNING OR PERFORATION OF THE SUB-FRAME STEEL. THE CORROSION IS FREQUENTLY VISIBLE AND OFTEN DISCOVERED DURING INSPECTION OR ROUTINE MAINTENANCE, AND OWNERS MAY ALSO HEAR NOISES OR NOTICE TIRE MISALIGNMENT AND STEERING PULL. IF THESE SIGNALS ARE UNDETECTED OR UNHEEDED, THE CORROSION MAY PROGRESS AND THE FORWARD MOUNTING OF THE LOWER CONTROL ARM MAY DETACH FROM THE SUB-FRAME.

Consequence

IF THAT HAPPENS, THE VEHICLE MAY LOSE DRIVE POWER TO THE WHEELS, AND THE FRONT WHEEL MAY MAKE CONTACT WITH THE FENDER OR WHEEL WELL, THEREBY INCREASING THE RISK OF A CRASH.

Remedy

DEALERS WILL MEASURE THE THICKNESS OF THE FRONT SUB-FRAME AND INSPECT THE FRONT SUB-FRAME FOR CORROSION DAMAGE AND, IF NECESSARY, THE FRONT SUB-FRAME WILL BE REPLACED WITH A NEW SUB-FRAME THAT INCORPORATES ADDITIONAL HOLES IN THE UPPER AND LOWER PANELS. IF THE FRONT SUB-FRAME DOES NOT REQUIRE REPLACEMENT, THE DEALER WILL ADD DRAINAGE HOLES TO THE SUB-FRAME AND WILL TREAT THE SUB-FRAME WITH RUST-PROOFING MATERIAL TO STOP THE CORROSION PROCESS. THIS PROCEDURE WILL BE PERFORMED FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN DURING APRIL 2009. OWNERS MAY CONTACT THE HYUNDAI CUSTOMER ASSISTANCE CENTER AT 1-800-633-5151.

THIS CONDITION ONLY RELATES TO THE DRIVER AND/OR PASSENGER SEAT-MOUNTED SIDE IMPACT AIR BAG(S).

Consequence

THIS CONDITION COULD PREVENT SEAT MOUNTED SIDE IMPACT AIR BAG DEPLOYMENT DURING AN ACCIDENT WHERE SUCH DEPLOYMENT SHOULD OCCUR. NON-DEPLOYMENT OF THE SRS SIDE IMPACT AIR BAGS COULD INCREASE THE RISK OF INJURY DURING AN ACCIDENT WHERE SIDE IMPACT AIR BAG DEPLOYMENT IS INTENDED.
