01V142000 · Equipment:Other:Labels

Reported: 2001-04-24 (April 24, 2001)

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.

Consequence: THESE VEHICLES WOULD NOT BE IN COMPLIANCE WITH FEDERAL REGULATIONS.

Remedy: 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.

03V126000 · Service Brakes, Air

Reported: 2003-03-31 (March 31, 2003)

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.

95V098000 · Seats

Reported: 1995-05-16 (May 16, 1995)

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

Consequence: 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.

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