2005 Kenworth C500 recalls

What's wrong: ON CERTAIN TRUCKS AND TRACTORS EQUIPPED WITH AIRGLIDE HIGH-ARTICULATION REAR SUSPENSIONS, THE C65-1006 SWAY BAR USED IN THIS REAR SUSPENSION MAY EXPERIENCE A REDUCTION IN FATIGUE LIFE DUE TO EITHER A MANUFACTURING PROCESS OR A HIGH INDUCED STRESS DURING AN EXTREME SUSPENSION ARTICULATION EVENT.

Risk: BOTH OF THESE CONDITIONS CAN LEAD TO A FAILURE OF THE SWAY BAR WHICH COULD CAUSE THE REAR AXLE TO COME LOOSE, INCREASING THE RISK OF A CRASH.

Free remedy: THE INSPECTION AND REPAIR OF THESE VEHICLES WILL DEPEND ON THE TYPE OF VEHICLE (TRACTOR OR TRUCK) AND THE INTENDED SERVICE APPLICATION. THIS INSPECTION AND REPAIR CRITERIA WILL BE FORTHCOMING. THE RECALL BEGAN ON JUNE 30, 2005. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440.

THE SLACK ADJUSTERS MAY FAIL AS A RESULT OF A FATIGUE CRACK RENDERING THE SLACK ADJUSTER INOPERATIVE. THIS COULD REDUCE BRAKING EFFECTIVENESS.

Risk: REDUCTION IN BRAKING CAPACITY COULD INCREASE THE RISK OF A CRASH.

Free remedy: DEALERS WILL INSPECT AND REPLACE THE SLACK ADJUSTERS FREE OF CHARGE. THE RECALL BEGAN ON MARCH 21, 2008. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440 AND PETERBILT AT 1-940-591-4196.

Risk: THE OIL LINE MAY BE CUT ON THE CYLINDER HEAD CAUSING AN OIL LEAK AND A POSSIBLE FIRE.

Free remedy: CATERPILLAR, IN CONJUNCTION WITH PACCAR, WILL BE CONDUCTING THE OWNER NOTIFICATION AND REMEDY FOR THIS CAMPAIGN FREE OF CHARGE. OWNERS MAY CALL CATERPILLAR AT 309-675-6496, KENWORTH AT 425-828-5440, OR PETERBILT AT 940-591-4201.

What's wrong: ON CERTAIN HEAVY DUTY CLASS 8 TRUCKS, THE SUSPENSION HAS TRANSVERSE BEAM CASTINGS THAT MAY FRACTURE UNDER NORMAL LOADS. IF A CASTING BREAKS WHEN THE VEHICLE IS TRAVELING ON A ROADWAY THERE IS THE POTENTIAL FOR PIECES OF THE CASTING TO BECOME PROJECTILES AND THE SUSPENSION'S TRANSVERSE BEAM MAY DROP DOWN LOW ENOUGH TO CONTACT THE ROAD SURFACE.

Risk: THIS COULD CAUSE SPARKS THAT COULD POTENTIALLY IGNITE AND CAUSE A FIRE.

Free remedy: DEALERS WILL INSPECT AND REPLACE THE DEFECTIVE TRANSVERSE BEAM ASSEMBLIES FREE OF CHARGE. THE RECALL BEGAN ON JUNE 10, 2005, WITH LETTERS BEING MAILED TO PETERBILT OWNERS; AND ON JUNE 17, 2005, FOR KENWORTH OWNERS. OWNERS MAY CONTACT PETERBILT AT 940-591-4201 OR KENWORTH AT 425-828-5440.

What's wrong: ON CERTAIN TRUCKS, THE WIRING, PARTS, OR TRANSMISSION PROGRAMMING REQUIRED FOR THE AUTO NEUTRAL FEATURE TO FUNCTION AS DESIGNED WERE EITHER NOT INSTALLED, CONNECTED, OR PROGRAMMED PROPERLY.

Risk: IF ANY OF THESE CONDITIONS EXISTS, THE TRANSMISSION WILL NOT AUTOMATICALLY SHIFT INTO NEUTRAL WHEN LEFT IN DRIVE WITH THE PARKING BRAKE SET ENGAGED. THE VEHICLE COULD MOVE WITHOUT WARNING INCREASING THE RISK OF A CRASH.

Free remedy: DEALERS WILL INSPECT THE AFFECTED VEHICLES TO ENSURE THE AUTO NEUTRAL FEATURE FUNCTIONS PROPERLY AND, IF NEEDED, WILL MAKE THE NECESSARY REPAIRS FREE OF CHARGE. THE RECALL BEGAN ON MAY 9, 2007. OWNERS MAY CONTACT KENWORTH AT 425-828-5440.
