CERTAIN PASSENGER VEHICLES MAY HAVE BEEN BUILT WITH A POWER STEERING HOSE THAT IS NOT TO SPECIFICATION. UNDER EXTREME STEERING MANEUVERS, SUCH AS TURNING THE STEERING WHEEL FULLY TO THE LEFT OR RIGHT WHILE BRAKING, THE HOSE MAY FRACTURE AND LEAK FLUID.

CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES MAY EXPERIENCE UNWANTED ANTILOCK BRAKE SYSTEM (ABS) ACTIVATION. THIS CONDITION IS MORE LIKELY TO OCCUR IN ENVIRONMENTALLY CORROSIVE AREAS. THIS RECALL WILL BE LAUNCHED IN THE "SALT BELT" STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MARYLAND, MASSACHUSETTS, MAINE, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN AND THE DISTRICT OF COLUMBIA ONLY.

APPROPRIATE USE OF A CHILD SEAT OR BOOSTER SEAT, AS RECOMMENDED FOR SMALL CHILDREN, DOES IMPROVE THE FIT CONDITION FOR THIS USER GROUP. IN ADDITION TO INSTRUCTIONS ON PROPER INFANT AND YOUNG CHILD RESTRAINT (WITH CHILD SEATS OR BOOSTERS), SPECIAL VERBIAGE FOR RESTRAINING OLDER CHILD IS INCLUDED IN THE OWNER'S MANUAL. ALSO, THE SUGGESTED SEAT BELT FIT/ROUTING FOR ADULTS, IRRESPECTIVE OF SEATING POSITION, IS DESCRIBED IN THE OWNER'S MANUAL TEXT.

CERTAIN TRUCKS, SPORT UTILITY VEHICLES, AND VANS EQUIPPED WITH BOSCH HYDRO-BOOST BRAKE ASSEMBLIES, THE HYDRAULIC BRAKE BOOSTER PRESSURE ACCUMULATOR MAY CRACK AND SEPARATE FROM THE HYDRO-BOOST ASSEMBLY DURING NORMAL OPERATING CONDITIONS.

ON CERTAIN SPORT UTILITY VEHICLES AND PICKUP TRUCKS EQUIPPED WITH 5.3L (RPO L59) V8 ENGINES, THE ENGINE FUEL RAIL CROSSOVER TUBE RETAINER SCREWS WERE NOT MANUFACTURED TO SPECIFICATIONS AND MAY BREAK.

CERTAIN PICKUP TRUCK, VAN, AND MINI VAN CONVERSIONS EQUIPPED WITH SOUTHERN COMFORT BUILT RUNNING BOARDS THAT CONTAIN CERTAIN COURTESY LIGHTS MANUFACTURED BY AMERICAN TECHNOLOGY COMPONENTS, INC.

ON CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES, VEHICLES, DURING A 30 DEGREE LEFT ANGLE FRONTAL IMPACT OF SUFFICIENT SEVERITY, A TEAR COULD DEVELOP IN THE MID-FRAME CROSS MEMBER AT ITS ATTACHMENT TO THE LEFT FRAME RAIL. IF THE MID-FRAME CROSS MEMBER TEARS DURING FRONTAL IMPACT AND PRODUCES A SHARP EDGE, CONTACT OF THE SHARP EDGE WITH THE FUEL TANK COULD RESULT IN A PUNCTURE OF THE FUEL TANK AND POSSIBLE FUEL LEAKAGE.

ON CERTAIN SPORT UTILITY VEHICLES EQUIPPED WITH REARWARD FOLDING HEAD RESTRAINTS ON THE SECOND ROW SEATS, TWO POTENTIAL PINCH POINTS EXIST ON EACH OF THE FOLDING HEAD RESTRAINTS WHEN THE RESTRAINTS ARE FOLDED REARWARD AS THE SEATBACK IS FOLDED DOWN.

VEHICLE DESCRIPTION: PICKUP AND UTILITY TRUCKS. SOME OF THESE VEHICLES HAVE AN INTERNAL COMPONENT IN THE OUTBOARD SEAT BELT RETRACTORS FOR THE 2ND AND 3RD ROW OF SEATS THAT COULD BE CRACKED. WITH REPEATED ACTUATION OF THE LOCKING MECHANISM, THE CRACK COULD SPREAD TO THE POINT SUCH THAT THE SEAT BELT WOULD NO LONGER LOCK.

VEHICLE DESCRIPTION: SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES WERE BUILT WITH A MISROUTED POSITIVE BATTERY CABLE ASSEMBLY THAT COULD COME IN CONTACT WITH THE STEERING SHAFT UNIVERSAL JOINT.

VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES.
