VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH MERITOR FG941 STEER AXLES. THE GROSS AXLE WEIGHT RATING (GAWR) WAS DETERMINED INCORRECTLY AND OVER-STATED ON THE VEHICLE CERTIFICATION LABEL. WITH THE INCORRECT GAWR LISTED, THESE LABELS DO NOT MEET THE CERTIFICATION REQUIREMENTS OF PART 567, "REQUIREMENTS FOR MANUFACTURERS OF MOTOR VEHICLES." VEHICLES WILL BE REMEDIED EITHER BY ASSIGNING THE PROPER WEIGHT RATING OR, IF POSSIBLE, BY CHANGING THE NECESSARY COMPONENTS TO MEET THE CURRENTLY ASSIGNED WEIGHT RATING.

THESE VEHICLES WOULD NOT BE IN COMPLIANCE WITH FEDERAL REGULATIONS.

VEHICLES WILL BE REMEDIED EITHER BY ASSIGNING THE PROPER WEIGHT RATING OR, IF POSSIBLE, BY CHANGING THE NECESSARY COMPONENTS TO MEET THE CURRENTLY ASSIGNED WEIGHT RATING. OWNER NOTIFICATION BEGAN JUNE 22, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT KENWORTH AT 1-425-828-5000.

ON CERTAIN VEHICLES EQUIPPED WITH CUMMINS ELECTRONIC CONTROL MODULES ON THE C8.3G AND L10G ENGINES, THE ECM DOES NOT HAVE THE ABILITY TO DETECT A THROTTLE FAIL-SAFE ENGINE SHUTDOWN COMMAND. THIS COULD RESULT IN AN UNANTICIPATED, UNCOMMANDED OPEN THROTTLE CONDITION WITHOUT WARNING.

IF THIS EVENT OCCURS, THE VEHICLE OPERATOR WILL NOT HAVE CONTROL OF THE ENGINE SPEED, POSSIBLY RESULTING IN A VEHICLE CRASH.

CUMMINS WILL NOTIFY THE CUSTOMERS AND REPLACE THE ECM. OWNERS SHOULD CONTACT CUMMINS AT 1-800-343-7357 OR KENWORTH AT 1-425-828-5440.

CERTAIN TRUCKS EQUIPPED WITH MERITOR P 18X7 BRAKES WITH 36" BRAKE CHAMBERS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD (FMVSS) NO. 121, "AIR BRAKE SYSTEMS." THESE TRUCKS WERE MANUFACTURED WITH A COMBINED AIR RESERVOIR VOLUME LESS THAN 12 TIMES THE COMBINED VOLUME OF ALL SERVICE BRAKE CHAMBERS.

THIS DOES NOT MEET THE REQUIREMENTS OF THE STANDARD.

DEALERS WILL ADD AN ADDITIONAL TANK OR CHANGE ONE OF THE EXISTING AIR TANKS TO A LARGER SIZE. OWNER NOTIFICATION BEGAN ON MAY 5, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT KENWORTH AT 1-425-828-5440.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH KENWORTH AIRGLIDE 200 REAR SUSPENSION. DUE TO MATERIALS USED IN THE SWAY BAR ARMS AND STUDS AS WELL AS THE STUD PLATING MATERIAL, STRESS CORROSION CRACKING AND BENDING FATIGUE CAN OCCUR IN THE REAR SUSPENSION SWAY BAR ARMS AND STUDS CAUSING THE STUD TO FAIL PREMATURELY.

THIS COULD CAUSE A LOSS OF STEERING CONTROL INCREASING THE RISK OF A VEHICLE CRASH.

DEALERS WILL REPLACE THE ARM ASSEMBLY MANUFACTURED FROM A DIFFERENT MATERIAL. NEW STUDS WILL BE INSTALLED WITH DIFFERENT THREADS AND DIFFERENT FINISH.

AN INTERFERENCE CONDITION BETWEEN THE BACK CUSHION AND THE RECLINER HANDLE CAN CAUSE AN INCOMPLETE LATCHING OF THE RECLINER MECHANISM.

THIS CONDITION CAN CAUSE THE SEAT BACK TO "RATCHET" REARWARD. REARWARD MOVEMENT OF THE SEAT BACK INCREASES TO WHERE THE SEATBACK HAS MOVED TO A FULLY RECLINED HORIZONTAL POSITION. COMPLETE LOSS OF BACK SUPPORT COULD CAUSE THE DRIVER TO LOSE CONTROL OF THE VEHICLE AND CAUSE AN ACCIDENT.

DEALERS WILL INSPECT THE SEAT AND, IF NECESSARY, INSTALL A NEW RECLINER LATCH SPRING AND HANDLE.
