ON CERTAIN TRUCKS EQUIPPED WITH THE BENDIX ELECTRONIC STABILITY CONTROL (ESP) SYSTEM, THE SYSTEM USES MULTIPLE SENSORS AND AN ELECTRONIC CONTROL UNIT (ECU) TO CONTROL VEHICLE UNDER STEER, OVER-STEER, AND ROLLOVER SITUATIONS. THE SYSTEM RELIES ON VEHICLE SENSORS TO BE FUNCTIONING AND ALIGNED PROPERLY. THE STEERING ANGLE SENSOR HAS THE POTENTIAL TO BE MISALIGNED WITH THE STEERING COLUMN SHAFT, THEREBY PROVIDING INCORRECT INFORMATION TO THE BENDIX ECU.

Consequence: THIS CONDITION COULD AFFECT VEHICLE THROTTLE CONTROL AND BRAKING, THEREBY LEADING TO LOSS OF VEHICLE STEERING CONTROL WHICH COULD CAUSE A CRASH WITHOUT WARNING.

Remedy: BECAUSE OF THE IMMEDIATE AND SUBSTANTIAL RISK, KENWORTH AND PETERBILT DEALERS WILL FIRST DEACTIVATE THE YAW CONTROL FEATURE OF THE BENDIX ESP SYSTEM PREVENTING INADVERTENT ESP ACTIVATION. WHEN PARTS ARE AVAILABLE, THE STEERING COLUMN WILL BE REPLACED TO INSURE PROPER ALIGNMENT OF THE STEERING SHAFT SENSOR AND THE FULL ESP SYSTEM WILL BE REACTIVATED.

ON CERTAIN TRUCKS, AN RA529 KING PIN RELEASE AIR VALVE WAS MANUFACTURED WITH THE INTERNAL SPOOL INSTALLED BACKWARDS. THIS RESULTS IN THE AIR OPTION OF THE KING PIN RELEASE SYSTEM BEING INOPERABLE. TO CORRECT THIS SITUATION, THE VEHICLE'S AIR LINES WERE REVERSED RATHER THAN REPLACING THE VALVE.

Consequence: WITH THE LINES REVERSED, THE KING PIN CAN BE RELEASED WITHOUT THE DRIVER'S KNOWLEDGE. WHEN THIS OCCURS, THE DRIVER COULD DRIVE AWAY AND THE TRAILER COULD BECOME DISENGAGED, INCREASING THE RISK OF A CRASH.

Remedy: KENWORTH WILL INSPECT THE KING PIN RELEASE SYSTEM AND SUSPECT VALVE. IF ANY VEHICLES HAVE A NONCONFORMING VALVE OR INCORRECT PLUMBING, IT WILL BE REPLACED AND RE-PLUMBED. THE RECALL BEGAN ON NOVEMBER 29, 2006. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440.

ON CERTAIN TRUCKS EQUIPPED WITH A TRW TILT/TELESCOPING STEERING COLUMN, THE TILT LOCKING MECHANISM ON THE STEERING COLUMN MAY DISENGAGE. THIS COULD PREVENT THE STEERING COLUMN FROM LOCKING IN TO PREDETERMINED POSITIONS.

Consequence: SHOULD THE LOCKING MECHANISM DISENGAGE, THE TILTING TRAVEL OF THE COLUMN WOULD BE UNRESTRICTED. THIS UNRESTRICTED TRAVEL ALLOWS THE STEERING WHEEL TO IMPACT THE DASH AND COULD LIMIT THE MOVEMENT OF THE STEERING WHEEL POTENTIALLY RESULTING IN DIFFICULTY MANEUVERING THE VEHICLE, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPLACE THE TILT LOCKING MECHANISM WITH A REVISED DESIGN THAT INCORPORATES A NEW BRACKET FOR RESTRAINING THE TILTING MECHANISM. THE RECALL BEGAN ON DECEMBER 22, 2006. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440.

CERTAIN TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS." THE TRAILER LIGHT LINE MAY HAVE BEEN ROUTED USING TOO TIGHT OF A BEND RADIUS. THIS ROUTING METHOD COULD CAUSE THE WIRES WITHIN THE HARNESS PLUG TO BE PULLED AWAY FROM THE CHASSIS PLUG RESULTING IN AN INTERMITTENT OR COMPLETE ELECTRICAL POWER LOSS TO THE TRAILER.

Consequence: SHOULD POWER BE LOST, THE ELECTRICAL CIRCUITS WOULD NOT PROVIDE POWER TO THE ANTILOCK SYSTEM ON THE TOWED VEHICLE INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REROUTE THE LIGHT LINE TO ELIMINATE THE EXCESSIVE BEND RADIUS AND REPLACE ANY PLUG OR HARNESS THAT HAS BEEN DAMAGED FREE OF CHARGE. THE RECALL BEGAN ON APRIL 16, 2007. OWNER MAY CONTACT KENWORTH AT 425-828-5440.

PACCAR IS RECALLING 172 MY 2007 KENWORTH T800 SHORT HOOD, W900 LONG HOOD AND T600 TRACTOR/TRAILERS EQUIPPED WITH SAF-HOLLAND SIMPLEX FIFTH WHEELS. IF THE PIVOT BOLT JOINT FOR THE LEVER BAR IS OVER TORQUED, THE SPACER DEFORMS, AND MAKES CONTACT WITH THE LEVER BAR. THIS CONDITION COUPLED WITH CORROSION ASSOCIATED WITH THE SEASONAL DRY OUT, CAN AFFECT THE LOCK SYSTEM OF THE FIFTH WHEEL, PREVENTING THE FIFTH WHEEL JAW FROM LATCHING SECURELY AROUND THE TRAILER KING PIN.

Consequence: THE FIFTH WHEEL MAY FAIL TO LATCH WITHOUT THE OPERATOR'S KNOWLEDGE, CAUSING THE TRACTOR AND TRAILER TO DISENGAGE INCREASING THE RISK OF A CRASH.

Remedy: KENWORTH IS WORKING WITH SAF-HOLLAND SIMPLEX AND WILL INSPECT THE PIVOT BOLT JOINT FOR A DEFORMED SPACER AND REPLACE THE BOLT, WASHER AND SPACER WITH A HEX-HEAD SHOULDER BOLT AND WASHER FREE OF CHARGE.

CERTAIN TRAILER CABLE MOUNTING BRACKETS HAVE A 'U-SHAPED' CUT OUT THAT ONLY PARTIALLY SUPPORTS THE TRAILER CABLE CONNECTION. PARTIAL SUPPORT OF THE CABLE CONNECTION MAY ALLOW THE MOLDED BOOT AND ELECTRICAL GROUND PIN TO PARTIALLY OR COMPLETELY PULL AWAY FROM THE 7-WAY SOCKET. PARTIAL OR COMPLETE DETACHMENT OF THE CABLE CONNECTION CAN CAUSE REDUCED WATER RESISTANCE AND POTENTIAL LOSS OF ELECTRICAL GROUND. THERE IS ALSO A POSSIBILITY THE TRAILER LIGHTS MAY FAIL TO ILLUMINATE WITHOUT THE OPERATOR'S KNOWLEDGE.

Consequence: IF THIS CONDITION WERE TO OCCUR, OTHER MOTORISTS MAY NOT BE WARNED OF THE TRACTOR/TRAILER MOVEMENTS, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL INSTALL A REINFORCEMENT BRACKET BETWEEN THE FLEXIBLE BACK OF THE QCS II MOLDED BOOT AND THE FRAME BRACKET, AND REATTACH THE SUPPORTING BOLTS. THE RECALL BEGAN ON MAY MAY 30, 2008. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440.

THE BEARING SURFACES OF THE EXTENDED LUBE UNIVERSAL JOINT THAT ATTACHES THE INTER-AXLE DRIVELINE TO THE DRIVE AXLE MAY BECOME PREMATURELY WORN DUE TO BREAKDOWN OF LUBRICATION AND/OR EXCESSIVE HEAT. PREMATURELY WORN BEARING SURFACES MAY RESULT IN THE U-JOINT BECOMING LOOSE AND/OR BINDING. THIS CONDITION MAY RESULT IN UNIVERSAL JOINT FAILURE, ALLOWING THE INTER-AXLE DRIVELINE TO DETACH FROM THE AXLE.

Consequence: DETACHMENT OF THE DRIVELINE FROM THE AXLE MAY CAUSE THE VEHICLE TO LOSE POWER AND BECOME DISABLED IN THE ROADWAY. ALSO, THE DRIVELINE COULD DROP FROM THE VEHICLE INTO THE ROADWAY INCREASING THE RISK OF A CRASH.
