3 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES, 2 AND 4-WHEEL DRIVE. SOLDER JOINTS NEAR THE WIRING HARNESS CONNECTOR CAN CRACK CAUSING THE WINDSHIELD WIPERS TO WORK INTERMITTENTLY.
Consequence
THIS CONDITION CAN RESULT IN INOPERATIVE WIPERS, REDUCING A DRIVER'S VISIBILITY, AND INCREASING THE RISK OF A VEHICLE CRASH.
Remedy
DEALERS WILL REPLACE THE WIPER MOTOR CIRCUIT BOARD AND COVER.
Defect
IF BOTH THE LAP-BELT AND SHOULDER-BELT ENERGY MANAGEMENT LOOPS ON THE FRONT SEAT BELT ASSEMBLIES RELEASE AT OR NEAR THE SAME TIME, ACCELERATION FORCES CAN CAUSE THE BUCKLE RELEASE MECHANISM TO ACTIVATE AND ALLOW THE BUCKLE TO SEPARATE FROM THE LATCH.
Consequence
IF THE BUCKLE RELEASED, THE SYSTEM WOULD FAIL TO PROVIDE ADEQUATE OCCUPANT RESTRAINT PROTECTION.
Remedy
DEALERS WILL REMOVE THE STITCHING THAT CREATES THE ENERGY MANAGEMENT LOOP IN THE SHOULDER BELT(S).
Defect
THESE VEHICLES WERE BUILT WITH FRONT SEAT BELT SYSTEMS WITH NO ENERGY MANAGEMENT LOOPS AND MAY NOT MEET THE HEAD INJURY CRITERIA REQUIREMENTS OF FMVSS NO. 208, "OCCUPANT CRASH PROTECTION."
Consequence
IN THE EVENT OF A VEHICLE CRASH, THE OCCUPANTS OF THESE SEATS MAY NOT BE PROPERLY RESTRAINED.
Remedy
DEALERS WILL REPLACE THE RETRACTOR PORTION OF THE SEAT BELT ASSEMBLY(S) WITH ONE HAVING THE NEWLY DESIGNED ENERGY-MANAGEMENT TWIN-LOOP SYSTEM.
