Recalls
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.
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.
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.
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.
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.
