Steering

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.

Air Bags

NISSAN IS RECALLING FORTY-SIX CERTAIN MODEL YEAR 2002 PATHFINDER AND INFINITI QX4 VEHICLES MANUFACTURED FROM AUGUST 24, 2001 THROUGH AUGUST 28, 2001. THE AIR BAG INFLATOR CONTAINS PROPELLANT WAFERS THAT ARE REQUIRED TO PROPERLY DEPLOY THE FRONT PASSENGER AIR BAG. DUE TO IMPROPER PROPELLANT WAFER INSTALLATION DURING THE AIR BAG INFLATOR ASSEMBLY PROCESS, SOME AIR BAG INFLATORS MAY BE MISSING ONE OF THE WAFERS. AS A RESULT, THE REMAINING WAFERS IN THE INFLATOR USED FOR THE DEPLOYMENT OF THE FRONT PASSENGER AIR BAG MAY, OVER TIME, BREAK UP INTO POWDER DUE TO NORMAL VIBRATION EXPERIENCED WHILE DRIVING. THIS CAUSES THE COMBUSTION RATE OF THE PROPELLANT TO INCREASE INSIDE THE INFLATOR, WHICH CAN LEAD TO INTERNAL PRESSURE RISING SUDDENLY DURING AIR BAG DEPLOYMENT.
