• 00V258001 Sep 2000 Equipment / Other / Labels

  Defect. VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES WERE BUILT WITH INCORRECT PAYLOAD INFORMATION ON THE VEHICLE CERTIFICATION LABEL. THE PAYLOAD SHOWN ON THE LABEL IS GREATER THAN THE MAXIMUM VALIDATED PAYLOAD. IF THE VEHICLE WERE LOADED TO THE INCORRECTLY LABELED PAYLOAD, IT MAY NOT RIDE AND HANDLE IN THE MANNER THAT THE DRIVER EXPECTS.

  Risk. THIS COULD RESULT IN A LOSS OF CONTROL OF THE VEHICLE OR AN INABILITY TO STOP THE VEHICLE WITHIN EXPECTED STOPPING DISTANCES.

  Remedy. OWNERS WILL BE SENT A NEW LABEL FOR INSTALLATION ON THE DRIVER'S DOOR OF THE VEHICLE.

• 00V055000 Feb 2000 Service Brakes, Hydraulic / Antilock/Traction Control/Electronic Limited Slip

  Defect. VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS EQUIPPED WITH 4-WHEEL DISC BRAKES. SOME OF THESE VEHICLES HAVE AN ANTILOCK BRAKE SYSTEM (ABS) MOTOR CONTAINING AN OUT-OF-SPECIFICATION SPRING CLIP. THIS CLIP COULD ALLOW THE MOTOR BEARING TO BECOME MISALIGNED. IF MISALIGNMENT OCCURS, EVENTUALLY THE ABS WOULD BE NON-FUNCTIONAL.

  Risk. THE BASE BRAKES WOULD REMAIN FULLY FUNCTIONAL, BUT THE DYNAMIC REAR PROPORTIONING (DRP) SYSTEM, WHICH OPTIMIZES FRONT TO REAR BRAKE BALANCE, WOULD BECOME INOPERATIVE.

  Remedy. DEALERS WILL REPLACE THE BRAKE PRESSURE MODULE VALVE ASSEMBLY.

• 99V220000 Aug 1999 Service Brakes, Hydraulic / Antilock/Traction Control/Electronic Limited Slip

  Defect. VEHICLE DESCRIPTION: S -TRUCKS EQUIPPED WITH 2 WHEEL DRIVE. THESE VEHICLES MAY HAVE HAD THE RIGHT-HAND ANTILOCK BRAKE SYSTEM (ABS) MODULE FEED PIPE AND/OR BRAKE CROSSOVER PIPE TUBE NUTS TIGHTENED WITHOUT SEATING THE PIPE-FLARED-ENDS ENOUGH TO WITHSTAND NORMAL ASSEMBLY AND VEHICLE INPUTS WITHOUT PARTIALLY UNSEATING. THIS DOES NOT COMPLY WITH REQUIREMENTS OF FMVSS NO. 105, "HYDRAULIC SERVICE BRAKE NORMAL, EMERGENCY, AND PARK BRAKING PERFORMANCE."

  Risk. IF THIS OCCURRED, THE SEATING SEAL COULD BE BROKEN DURING VEHICLE ASSEMBLY, OR FROM EARLY ROAD INPUTS OR BRAKE FLUID CYCLING, AND A LEAK COULD OCCUR INCREASING THE BRAKE STOPPING DISTANCE.

  Remedy. DEALERS WILL INSPECT THE BRAKE PIPE UNION FOR SIGNS OF BRAKE FLUID, AND IF NECESSARY, INSTALL A NEW BRAKE PIPE UNION.
