2007 Kenworth T300 problems

Defect

PACCAR IS RECALLING 36 MY 2007-2008 T270, T370 AND MY 207 T300 TRUCKS EQUIPPED WITH DUAL UNDER-CAB FUEL TANKS AND AN IN-CAB BATTERY BOX (ICBB). A HARNESS SUPPORT BRACKET MOUNTED ON THE UNDERSIDE OF THE CAB MAY COME IN CONTACT WITH THE FUEL LINE AT THE TOP OF THE FUEL SPLITTER VALVE.

Consequence

THE EDGE OF THE BRACKET MAY COMPROMISE THE FUEL LINE CAUSING AN INTERRUPTION IN FUEL FLOW, OR LOSS OF FUEL RESULTING IN COMPROMISED VEHICLE PERFORMANCE OR POTENTIALLY CAUSING A FIRE.

Remedy

DEALERS WILL RE-WORK THE EXISTING ICBB CABLE ROUTING BRACKET AND REPLACE THE FUEL SPLITTER VALVE BRACKET TO PROVIDE ADEQUATE CLEARANCE BETWEEN COMPONENTS. THE RECALL BEGAN O JUNE 30, 2008. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440.

Defect

ON CERTAIN TRUCKS EQUIPPED WITH CUMMINS ISC OR PACCAR PX8 ENGINES, THE JUMPER WIRE BETWEEN THE GRID HEATER RELAY TO THE FUSE BLOCK HAS BEEN ROUTED IN SUCH A WAY THAT THE POTENTIAL EXISTS FOR IT TO RUB AGAINST THE RADIATOR SUPPORT.

Consequence

THE SUSPECT WIRE IS DOWN STREAM OF THE FUSE; THIS CHAFF POINT COULD CAUSE THE 250 AMP CHARGE WIRE TO ARC, POTENTIALLY CAUSING A FIRE.

Remedy

DEALERS WILL INSPECT THE ROUTING OF THE JUMPER WIRE. IF THE WIRE IS NOT ROUTED CORRECTLY, IT WILL BE INSPECTED FOR RUBBING OR CHAFFING AND REPLACED IF NECESSARY FREE OF CHARGE. THE RECALL BEGAN ON JUNE 22, 2007. OWNERS MAY CONTACT KENWORTH AT 425-828-5440.

Defect

ON CERTAIN TRUCKS, THE AXLE HOUSINGS MAY HAVE BEEN MANUFACTURED WITH STEEL THAT WAS OUT OF SPECIFICATION WHICH COULD RESULT IN A FATIGUE FAILURE OVER TIME.

Consequence

IF A FATIGUE FAILURE OCCURS AND IS LEFT UNATTENDED, THE AXLE MAY LOCK UP OR THE END OF THE AXLE COULD COME OFF, WHICH MAY RESULT IN A VEHICLE CRASH.

Remedy

DEALERS WILL INSPECT AND REPLACE THE AXLES FREE OF CHARGE. THE RECALL BEGAN ON MAY 9, 2007. OWNERS MAY CONTACT KENWORTH AT 425-828-5440 AND PETERBILT AT 1-940-591-4196.

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.

Consequence

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.

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.

Defect

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.
