NCAP overall
5 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
VEHICLE DESCRIPTION: TRUCKS ASSEMBLED WITH SKF LEVEL 2 TRUCK HUB UNITS (THU) RECEIVED FROM MERITOR. THESE HUBS CAN FATIGUE CRACK.
Consequence
THIS FATIGUE CRACKING CAN RESULT IN WHEEL SEPARATION, INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL REPLACE THESE HUBS WITH PRODUCTION LEVEL 3 HUBS.
Defect
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH SPICER SPL170 55MM CENTER BERING PACKAGE. THE END YOKE RETAINING NUT CAN LOOSEN.
Consequence
IF THIS CONDITION OCCURS, THE DRIVE LINE CAN VIBRATE AND SEPARATE FROM THE VEHICLE, CAUSING VEHICULAR DAMAGE, OR PERSONAL INJURY, OR BOTH.
Remedy
DEALERS WILL REMOVE THE 55MM CENTER BEARING PACKAGE AND COUPLER SHAFT, AND REPLACE IT WITH A NEW COUPLER SHAFT AND A 60MM CENTER BEARING PACKAGE. AN INTERIM REMEDY CAN BE IMPLEMENTED BY PLACING A SPOT WELD ON THE COUPLING SHAFT THREADS UNTIL PARTS ARE AVAILABLE.
Defect
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH PROSLEEPER BUNKS. A MICRO RELAY LOCATED BEHIND THE HVAC CONTROL PANEL IN THE BUNK CAN CORRODE FROM MOISTURE.
Consequence
THIS CONDITION CAN RESULT IN A SHORT CIRCUIT BETWEEN CONTACTS ON THE RELAY INCREASING THE RISK OF A VEHICLE FIRE.
Remedy
DEALERS WILL REMOVE THE EXISTING RELAY AND REPLACE IT WITH A SEALED RELAY.
Defect
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH ANTILOCK BRAKE SYSTEM (ABS). THE WIRING FROM THE ELECTRONIC CONTROL UNIT WAS CONNECTED TO THE WRONG WHEEL SENSOR.
Consequence
SHOULD THE ABS WIRING BE CROSSED, IT WOULD RESULT IN A SIGNIFICANT DEGRADATION IN BRAKING STABILITY. A SIGNAL WOULD BE SENT TO THE WRONG BRAKE CHAMBER WHEN A BRAKE IMBALANCE IS DETECTED INCREASING THE RISK OF A VEHICLE CRASH.
Remedy
DEALERS WILL INSPECT THE ABS WIRING AND PROPERLY CONNECT THE WIRES, IF NECESSARY.
Defect
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH SIX-SPOKE WHEEL ASSEMBLIES. THESE VEHICLES WERE MANUFACTURED WITH THE WRONG COMBINATIONS OF WHEEL ASSEMBLY PARTS. SHOULD THE SIX-SPOKE WHEEL ASSEMBLY HAVE MIS-MATCHED PARTS, HIGH STRESSES IN THE WHEEL STUDS AND POTENTIAL WHEEL FAILURES CAN OCCUR.
Consequence
STUD FAILURES CAN OCCUR RESULTING IN A WHEEL SEPARATION INCREASING THE RISK OF A VEHICLE CRASH.
Remedy
DEALERS WILL INSPECT THESE WHEELS AND MAKE THE NECESSARY COMBINATION CORRECTIONS. ALSO OPERATOR INSTRUCTIONS AND VISUAL AIDS WILL BE UPDATED.
