NISSAN IS RECALLING CERTAIN MODEL YEAR 1996-2004 PATHFINDER AND MODEL YEAR 1997-2003 INFINITI QX4 VEHICLES ORIGINALLY SOLD, OR CURRENTLY REGISTERED IN, CONNECTICUT, DELAWARE, IOWA, ILLINOIS, INDIANA, MASSACHUSETTS, MAINE, MARYLAND, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WASHINGTON D.C., WEST VIRGINIA AND WISCONSIN. IN AREAS OF THE COUNTRY IN WHICH HEAVY CONCENTRATIONS OF ROAD SALT ARE USED, A MIXTURE OF SNOW/WATER AND SALT MAY ENTER AN ASSEMBLY LOCATION HOLE IN THE UPPER STRUT HOUSING, CAUSING WATER TO COLLECT AT THE MATING SURFACE OF THE STRUT HOUSING PANEL AND THE INNER HOOD LEDGE ASSEMBLY. OVER TIME, THIS SNOW/WATER AND SALT INTRUSION MAY RESULT IN CORROSION OF THE STRUT TOWER HOUSING IN SOME SUBJECT VEHICLES.
ON CERTAIN VEHICLES ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, DELAWARE, IOWA, ILLINOIS, INDIANA, KENTUCKY, MASSACHUSETTS, MAINE, MARYLAND, MICHIGAN, MINNESOTA, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, TENNESSEE, VERMONT, VIRGINIA, WEST VIRGINIA , WISCONSIN AND THE DISTRICT OF COLUMBIA, DURING THE COATING PROCESS OF THE FUEL FILLER TUBE ASSEMBLY, AN INSUFFICIENT AMOUNT OF COATING MAY HAVE BEEN APPLIED AT THE LOWER MOUNTING BRACKET. THIS COULD RESULT IN AN OPENING IN THE COATING WHICH CAN ALLOW WATER TO ENTER AND MAKE CONTACT WITH THE BARE METAL OF THE TUBE.
VEHICLE DESCRIPTION: SPORT UTILITY VEHICLES. SOME OF THE BRACKETS USED TO ATTACH THE TWO GAS STRUTS TO THE REAR DOOR (HATCH) MAY HAVE BEEN IMPROPERLY MADE. AT HIGH AMBIENT TEMPERATURES, THE INCREASE IN GAS PRESSURE IN THE STRUT(S) COULD CAUSE ONE OR BOTH BRACKETS TO BEND, RESULTING IN THE STRUTS DETACHING FROM THE BRACKET(S) WHEN OPENING OR CLOSING THE REAR DOOR.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THESE VEHICLES MAY HAVE AN IGNITION LOCK ASSEMBLY WITH IMPROPERLY SEATED KEY CYLINDER CAP CONNECTOR PINS. VIBRATION CAN CAUSE THE CONNECTING PINS TO LOOSEN AND/OR FALL OUT ALLOWING THE KEY CYLINDER CAP TO DISENGAGE FROM THE KEY CYLINDER.
