2009 Kenworth T2000: complaints, problems and recalls

Reported: 2008-03-21 (March 21, 2008)

PACCAR IS RECALLING 1,043 MY 2008-2009 KENWORTH C500, T2000,T660, T800 AND W900 TRUCKS EQUIPPED WITH BENDIX MV-3 DASH CONTROL VALVES. 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.

KENWORTH IS RECALLING 1,189 MY 2009 T2000, T600, T660, T800 AND W900 TRUCKS. THE AXLE U-BOLTS ATTACHING THE AXLE TO THE DRIVE BEAM ON CERTAIN AG380 REAR SUSPENSIONS MAY HAVE RECEIVED INSUFFICIENT FASTENER TORQUE DURING THE INSTALLATION PROCESS.

Consequence: THE INSUFFICIENT TORQUE MAY ALLOW THE AXLE U-BOLT TO LOOSEN IF UNDETECTED, COULD IMPACT LONG TERM SUSPENSION PERFORMANCE AND INCREASE THE RISK OF A CRASH.

Remedy: DEALERS WILL HAVE THE AXLE U-BOLT ON THE AFFECTED CHASSIS RE-TORQUED TO FACTORY SPECIFICATIONS FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 12, 2008. OWNERS MAY CONTACT KENWORTH AT 425-828-5440.

PACCAR IS RECALLING 130 MY 2004-2009 T2000, T800, T600, W900 AND T660 KENWORTH TRUCKS BUILT WITH AN AG400 REAR SUSPENSION, LONG STROKE BRAKE CHAMBERS, AND WIDE BASE TIRES (SUPER SINGLES). THESE VEHICLES MAY DEVELOP AN INCREASE IN LATERAL AND VERTICAL AXLE MOVEMENT. THIS MOVEMENT MAY CAUSE PART OR PARTS OF THE BRAKE ASSEMBLY (BRAKE CAM TUBE SUPPORT, BRAKE CHAMBER BRACKET, BRAKE CHAMBER, BRAKE SPIDER) TO DEVELOP FATIGUE CRACKS, POSSIBLY RESULTING IN THE FAILURE OF THE PART OR PARTS WITHIN THE BRAKE ASSEMBLY.

Consequence: A FAILURE MAY REDUCE VEHICLE BRAKE PERFORMANCE, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL INSTALL THE CAM TUBE SUPPORT BRACKETS ON ALL OF THE REAR AXLE WHEEL ENDS. INSPECT THE REAR AXLE BRAKE ASSEMBLY AND REPLACE IT IF CRACKED. THE RECALL IS EXPECTED TO BEGIN DURING NOVEMBER 2008. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440.

Reported: 2009-06-18 (June 18, 2009)

KENWORTH IS RECALLING 13 MY 2009 T2000 VEHICLES FOR FAILING TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 106, "BRAKE HOSES." AIR TUBE EXPANDER FITTING USED BETWEEN THE AIR TUBE INLET AND DASH AIR GAUGES FOR THE TRAILER DOES NOT MEET THE BURST PRESSURE REQUIREMENTS.

Consequence: THIS CAN RESULT IN BRAKE HOSE RUPTURE, AIR PRESSURE LOSS, AND COMPROMISED VEHICLE BRAKING WHICH COULD RESULT IN A CRASH WITHOUT WARNING.

Remedy: DEALERS WILL INSPECT AND REPLACE THE EXPANDER FITTING WHICH IS RELATED TO 1,200 PSI. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON JUNE 3, 2009. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440.

KENWORTH IS RECALLING 3,423 MY 2004-2009 T2000, T800,T600, W900 AND T660 VEHICLES. INCREASED BRAKE EXCITATION IN A CERTAIN VEHICLE CONFIGURATION WHICH INCLUDES BENDIX DRUM BRAKES, WIDE BASE LOW PROFILE SINGLE TIRES, AND AN AG400 OR AG460 REAR SUSPENSION, DUE TO ITS UNIQUE BRAKE CLOCKING AND CAM TUBE LENGTH, CAN CAUSE FATIGUE AND CRACKING TO BRAKE ASSEMBLY COMPONENTS.

Consequence: CRACKING CAN CAUSE A COMPLETE FRACTURE OF THE CAM TUBE, WHICH COULD INCREASE STOPPING DISTANCE AND DECREASE PARKING BRAKE HOLD CAPABILITY.

Remedy: DEALERS WILL INSPECT THE REAR AXLE BRAKES ASSEMBLY, REPLACE CRACKED REAR AXLE BRAKES ASSEMBLY COMPONENTS WHERE REQUIRED, AND INSTALL CAM TUBE SUPPORT BRACKETS ON ALL REAR AXLE WHEEL ENDS FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN OR BEFORE JULY 25, 2009. OWNER MAY CONTACT KENWORTH AT 1-425-828-5440.

Reported: 2009-07-08 (July 8, 2009)

PACCAR IS RECALLING 2,096 MY 2009 KENWORTH AND PETERBILT VEHICLES EQUIPPED WITH TRW STEERING SHAFTS. MISLOCATION OF A CIRCUMFERENTIAL WELD MAY ALLOW THE SPLINED TUBE AND NON-SPLINED TUBE TO ROTATE RELATIVE TO ONE ANOTHER DURING A LOW SPEED, HIGH TORQUE TURN, POSSIBLY RESULTING IN A SEPARATION OF THE TWO TUBES.

Consequence: A SEPARATION OF THE SPLINED AND NON-SPLINED TUBES COULD CAUSE A LOSS OF STEERING CONTROL AND INCREASE THE RISK OF A CRASH.

Remedy: DEALERS WILL INSPECT THE STEERING SHAFT USING A WELD PLACEMENT GAUGE AND MISWELDED STEERING SHAFT WILL BE REPLACED FREE OF CHARGE. THE RECALL BEGAN JULY 31, 2009. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440 AND PETERBILT AT 1-940-591-4196.

Reported: 2009-10-21 (October 21, 2009)

KENWORTH IS RECALLING MODEL YEAR 2009 THROUGH 2010 T2000, T800, T660 AND W900 TRUCKS MANUFACTURED BETWEEN NOVEMBER 12, 2008 AND SEPTEMBER 30, 2009. THE AXLE U-BOLTS ATTACHING THE AXLE TO THE SUSPENSION LEAF SPRING ON CERTAIN AG400L REAR SUSPENSIONS MAY HAVE RECEIVED INSUFFICIENT FASTENER TORQUE DURING THE INSTALLATION PROCESS. THE INSUFFICIENT TORQUE MAY ALLOW THE AXLE U-BOLT TO BECOME LOOSE, WHICH MAY CAUSE VIBRATION IN THE REAR SUSPENSION.

Consequence: IF MULTIPLE FASTENERS WERE TO BECOME LOOSE, THE REAR AXLE MAY SHIFT RELATIVE TO THE REAR SUSPENSION LEAF SPRING, WHICH CAN RESULT IN LOSS OF CONTROL AND A CRASH.

Remedy: DEALERS WILL INSPECT THE AXLE U-BOLTS FOR VISIBLE DEFECTS, INCLUDING BENT AND/OR SMASHED THREADS AND RE-TORQUE THE AXLE U-BOLTS TO FACTORY SPECIFICATIONS. THE RECALL BEGAN ON NOVEMBER 4, 2009. OWNERS MAY CONTACT KENWORTH AT 425-828-5440.

Reported: 2010-07-02 (July 2, 2010)

PACCAR IS RECALLING CERTAIN MODEL YEAR 2008-2010 TRUCKS EQUIPPED WITH TRW STEERING SHAFTS. THE CIRCUMFERENTIAL WELD AROUND THE STEERING SHAFT TUBE THAT WELDS THE SPLINED TUBE TO THE NON-SPLINED TUBE MAY BE MISLOCATED. MISLOCATION OF THE CIRCUMFERENTIAL WELD MAY ALLOW THE SPLINED TUBE AND NON-SPLINED TUBE TO ROTATE RELATIVE TO ONE ANOTHER DURING A LOW SPEED, HIGH TORQUE TURN, POSSIBLY RESULTING IN A SEPARATION OF THE TWO TUBES.

Consequence: A SEPARATION OF THE SPLINED AND NON-SPLINED TUBES WOULD CAUSE A LOSS OF STEERING CONTROL AND INCREASE THE RISK OF A VEHICLE CRASH.

Remedy: DEALERS WILL INSPECT THE STEERING SHAFT USING A WELD PLACEMENT GAUGE PROVIDED BY TRW. ANY STEERING SHAFT FOUND TO HAVE BEEN WELDED IMPROPERLY WILL BE REPLACED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON JULY 30, 2010. OWNERS MAY CONTACT KENWORTH AT 425-828-5440 AND PETERBILT AT 940-591-4196.

THE OIL MODULE CENTRIFUGAL SPINNER FILTER CAP IN THE PACCAR MX ENGINE MAY BECOME LOOSE, POSSIBLY ALLOWING THE CAP TO COME OFF AND ENGINE OIL TO PARTIALLY DISCHARGE FROM THE OIL MODULE ONTO EXHAUST COMPONENTS.

Consequence: THE DISCHARGE OF ENGINE OIL ONTO EXHAUST COMPONENTS WHICH ARE HOT, SUCH AS WHEN THE ENGINE IS UNDER SIGNIFICANT LOAD, MAY CAUSE A FIRE.
