01V066000 · Steering

Reported: 2001-03-07 (March 7, 2001)

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS. THE BOLTS USED TO SECURE THE STEERING SHAFT CAN FAIL.

Consequence: THIS CONDITION CAN RESULT IN THE LOSS OF VEHICLE CONTROL WITHOUT WARNING, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPLACE THE DEFECTIVE BOLTS. OWNER NOTIFICATION BEGAN APRIL 2, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT PETERBILT AT 1-940-591-4000.

01V179000 · Latches/Locks/Linkages:Doors:Latch

Reported: 2001-06-05 (June 5, 2001)

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS. A CHANGE IN THE INTERNAL LINKAGE OF CERTAIN CAB DOORS HAS CREATED A POSSIBLE BINDING CONDITION.

Consequence: IF THE LINKAGE BINDS, FULL ENGAGEMENT OF THE DOOR LATCH MAY NOT OCCUR, ALLOWING THE DOOR TO OPEN INADVERTENTLY.

Remedy: DEALERS WILL MODIFY THE DOOR LINKAGE TO CORRECT THE POTENTIAL OF BINDING. OWNER NOTIFICATION BEGAN JUNE 22, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT PETERBILT AT 1-940-591-4000.

NHTSA campaign record ↗

02V018001 · Service Brakes, Air:Supply:Check Valve

Reported: 2002-01-15 (January 15, 2002)

ON CERTAIN HEAVY DUTY TRUCKS EQUIPPED WITH MERITOR WABCO PNEUMATIC ANITLOCK BRAKE SYSTEM (ABS) VALVE PACKAGES, THE ASSEMBLY BOLTS ON THESE VALVE PACKAGES WERE NOT TIGHTENED CORRECTLY.

Consequence: BOLTS TORQUED BELOW SPECIFICATION WILL NOT RELIABLY PREVENT AIR LEAKAGE AT THE AFFECTED ABS VALVE PACKAGE INTERFACE JOINTS ONCE THE COMPONENT BEGINS NORMAL VEHICLE OPERATION. IF AIR LEAKS DEVELOP AT ANY OF THE ABS VALVE PACKAGE INTERFACE JOINTS, BRAKE SYSTEM PRESSURE REDUCTIONS COULD OCCUR DURING BRAKING OR NORMAL OPERATION WITH UNITS EQUIPPED WITH THE TRACTION CONTROL OPTION, POTENTIALLY EXTENDING STOPPING DISTANCES, POSSIBLY RESULTING IN A VEHICLE CRASH.

Remedy: DEALERS WILL TIGHTEN THE FASTENERS TO THE PROPER SPECIFICATION. OWNER NOTIFICATION BEGAN FEBRUARY 15, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT KENWORTH AT 1-425-828-5440 OR PETERBILT AT 1-940-591-4201.

OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITH A REASONABLE TIME SHOULD CONTACT PETERBILT AT 940-591-4201 OR KENWORTH 425-828-5440.
