CERTAIN TRUCKS FAIL TO COMPLY WITH THE BRAKE TIMING REGULATORY REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS." THE BRAKE VALVE WAS MOVED TO THE OPPOSITE RAIL, INCREASING THE LENGTH OF THE AIR LINE, WHICH IN TURN INCREASED THE WHEELBASE REQUIRING A DUAL RELAY VALVE SYSTEM. THE VEHICLES WERE MANUFACTURED WITH A SINGLE VALVE SYSTEM.

Consequence: IF STOPPING DISTANCE WAS LIMITED, A VEHICLE CRASH COULD RESULT.

Remedy: DEALERS WILL CONVERT THE SINGLE RELAY VALVE TO A DUAL RELAY VALVE SYSTEM FREE OF CHARGE. THE RECALL BEGAN ON MAY 21, 2007. OWNERS MAY CONTACT KENWORTH AT 425-828-5440.

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.

CERTAIN TRUCKS EQUIPPED WITH EATON SYNFLEX ECLIPSE BRAND EXTRUDED NYLON AIR BRAKE HOSE TUBING FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 106, "BRAKE HOSES." THE TUBING WAS MANUFACTURED WITH ONLY FOUR LAYERS OF NYLON MATERIAL, INSTEAD OF THE SPECIFIED FIVE LAYERS.

Consequence: THE DIAMETER OF THE HOSE AFFECTS THE FITTINGS WHICH MAY ALLOW AIR TO LEAK FROM THE BRAKES AND CREATE THE POTENTIAL FOR A VEHICLE CRASH.

Remedy: DEALERS WILL INSPECT THE AIR BRAKE HOSES AND, IF NECESSARY, REPLACE THE HOSES. THE RECALL BEGAN ON FEBRUARY 22, 2008. OWNER NOTIFICATION SCHEDULE FOR THIS CAMPAIGN. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440 OR PETERBILT AT 1-940-591-4196.

CERTAIN DOOR LATCH ASSEMBLIES ON THESE VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 206, 'DOOR LOCKS AND DOOR RETENTION COMPONENTS." THE ROTOR IN SOME OF THESE DOOR LATCH ASSEMBLIES DID NOT RECEIVE THE PROPER HEAT TREATMENT AND MAY BE SOFT.

Consequence: IN THE EVENT OF A CRASH, FORCE COULD CAUSE THE ROTOR TO CRACK AND THE DOOR WOULD NOT HAVE PRIMARY OR SECONDARY CLOSING SECURITY WHICH COULD POSSIBLY LEAD TO INJURY OF THE VEHICLE OCCUPANT.

Remedy: PACCAR IS WORKING WITH TRIMARK AND WILL INSPECT AND REPLACE THE DOOR LATCH IF IT IS FOUND TO BE DEFECTIVE. THE RECALL BEGAN ON MARCH 14, 2008. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440 OR PETERBILT AT 1-940-591-4196.

THE MOLDED VALVE BODY HAS AN INCORRECT CORE PIN IN THE INJECTION MOLD CAUSING THE VALVE BODY TO BE OVERSIZED IN THE DOUBLE CHECK VALVE AREA. THIS CONDITION CAN ALLOW THE RUBBER DOUBLE CHECK VALVE TO BECOME LODGED IN THE BODY OPENING UNDER CERTAIN CIRCUMSTANCES.

Consequence: IF THE DOUBLE CHECK VALVE BECOMES LODGED, IN THE EVENT OF A PRIMARY RESERVOIR FAILURE, AIR PRESSURE CAN LEAK PAST THE LODGED DOUBLE CHECK VALVE THEREBY DEPLETING THE SECONDARY RESERVOIR, CAUSING REDUCED ABILITY FOR MODULATING THE SERVICE EMERGENCY BRAKES. IN SUCH AN EVENT, THE OPERATOR SHOULD OBSERVE AN AIR LEAK, INDICATIONS OF LOW AIR PRESSURE VIA THE PRIMARY AND SECONDARY AIR GAUGES, AND AUDIBLE AND VISUAL LOW AIR PRESSURE WARNING ALARMS. A VEHICLE CRASH IS POSSIBLE IF THESE WARNINGS ARE NOT HEEDED.

Remedy: DEALERS WILL REPLACE THE BENDIX MV-3 DASH CONTROL VALVES FREE OF CHARGE. THE RECALL BEGAN ON APRIL 14, 2008. OWNERS MAY CONTACT KENWORTH AT 1-425-828-4196.
