Defect. 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.

Risk. 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.

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.

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

Defect. 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.

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.

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.

Defect. ON CERTAIN TRUCKS BUILT WITH THE OPTIONAL DANA SPL DRIVELINE, THE U-JOINT FASTENERS AT THE OUTPUT YOKE OF THE TRANSMISSION WERE NOT PROPERLY TIGHTENED.

2004 KENWORTH W9, WAS ENTERING ONTO THE OHIO TURNPIKE WHEN ITS RIGHT REAR TRAILER TIRE CAUGHT ON FIRE *BF THE DRIVER WAS ABLE TO PUT THE FIRE OUT, USING A FIRE EXTINGUISHER. (OHIO TRAFFIC CRASH REPORT # 10-0690-91). *JB UPDATED 01/14/11 *BF

THIS HAD HAPPENED TO MY PARENTS. MY DAD DRIVES A KENWORTH T2000 IT IS A BRAND NEW 2004. MY DAD WAS PARKING HIS TRUCK FOR THE NIGHT IN WACO, TX WHEN HE HAD SMELT SOMETHING BURNING. HE OPENED THE HOOD OF THE TRUCK AND THERE WAS A FIRE BETWEEN THE ENGINE AND THE FIREWALL. THEY BELIEVE THE FIRE STARTED WITH A WIRE ON THE ALTERNATOR. OUR CONCERN IS THE KENWORTH T2000 DOES NOT HAVE A DOOR ON THE SLEEPER BIRTH. WE BELIEVE THAT ALL SEMI TRUCKS NEED ONE. IF MY PARENTS HAD BEEN SLEEPING THERE WOULD HAVE BEEN NO WAY FOR THEM TO ESCAPE THE TRUCK IF THE FIRE HAD GOT BIG ENOUGH. I HAVE WROTE TO OTHER PEOPLE BUT NO ONE SEEMS TO CARE ABOUT IT WHICH SHOWS ME THAT NO ONE GIVES A [XXX] THING, BUT I BET IF THEY HAD DIED IN THAT TRUCK EVERYONE WOULD BE COMPLAINING THAT NO ONE HAD SAID A THING ABOUT IT. I AM BEGGING YOU SOMETHING NEEDS TO BE DONE TO MAKE DOORS IN THE SLEEPER MANDATORY ON ALL SEMI TRUCKS WITH SLEEPER BIRTHS.*AK INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
