1997 Kenworth T800

Defect. 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.

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

Remedy. 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.

Defect. 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.

Risk. THIS DOES NOT MEET THE REQUIREMENTS OF THE STANDARD.

Remedy. 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.

Risk. THE COMBINATION OF COMPONENTS COULD REDUCE THE SERVICE LIFE OF THE FRONT HUB, WHICH COULD RESULT IN A FRACTURE. IF A HUB FRACTURES, VEHICLE CONTROL, BRAKING, AND STABILITY CAN BE AFFECTED. IN EXTREME CASES, THE WHEEL COULD SEPARATE FROM THE VEHICLE CAUSING A LOSS OF VEHICLE CONTROL, INCREASING THE RISK OF A CRASH.

Defect. VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH MERITOR FG941 STEER AXLES.

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.

Risk. THESE VEHICLES WOULD NOT BE IN COMPLIANCE WITH FEDERAL REGULATIONS.
