MY VEHICLE HAS BEEN HAVING A HESITATION PROBLEM FOR SOME TIME NOW. I HAVE TAKEN IT TO SEVERAL MECHANICS AND HAVE NOT FOUND THE PROBLEM AFTER SPENDING SEVERAL THOUSAND DOLLARS. I TOOK IT TO THE LOCAL DEALER (BROWN HYUNDAI) IN LAREDO TX AND THEY POINT TO THE CATALYTIC CONVERTERS (3) AND THE OXYGEN SENSORS. I HAVE HAD A MECHANIC REMOVE THE CATALYTIC CONVERTS AND TELL ME THERE IS NOTHING WRONG WITH THE CONVERTERS. THE VEHICLE EXHAUST SYSTEM REACHES OVER 500 DEGREES. I HAVE MEASURED IT WITH A HEAT GUN. WHILE I DO NOT KNOW WHAT THE PROPER TEMPERATURE SHOULD BE I KNOW OVER 500 DEGREES IS WAY TO HIGH. WHILE I WENT TO PICK UP MY HYUNDAI AT THE DEALER HE TOLD ME THEY HAD JUST HAD 2 OTHER VEHICLES XG350'S WITH THE EXACT PROBLEM. IF YOU GO ON LINE AND READ SOME OF THE CODES THEY REFER TOO "BAND 1 AND BANK 2 SYSTEM TOO LEAN", THIS IS A VERY COMMON PROBLEM WITHOUT AN EXACT SOLUTION. I BELIEVE THE CODE IS P0174 AND P0171. BOTH THE MECHANICS I HAVE HIRED AND THE DEALER HAVE CHECKED THE LIST OF POSSIBLE PROBLEMS WHICH INCLUDE: INTAKE AIR LEAKS OXYGEN SENSORS IGNITION MISFIRING FUEL INJECTORS FUEL PRESSURE MASS AIR FLOW SENSOR. *TR

Official recalls

09V124000 · Suspension

Apr 16, 2009

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 & remedy

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.
