1998 Nabi 40lfw problems

Defect

ON CERTAIN TRANSIT BUSES, THE FRONT AXLE STOPS AND THE POWER STEERING GEAR HYDRAULIC LIMIT VALVES WERE FOUND TO BE OUT OF ADJUSTMENT. THE DRAG LINK MAY EXPERIENCE PERMANENT DEFORMATION DUE TO THE STEERING LOAD.

Consequence

DURING LONG TERM OPERATION INVOLVING REPEATED FLEXING OF THE DRAG LINK, IT MAY EVENTUALLY CRACK AND BREAK. THE DRIVER WILL NO LONGER HAVE STEERING CONTROL OF THE VEHICLE AND A CRASH COULD OCCUR CAUSING INJURY OR DEATH.

Remedy

DEALERS WILL INSPECT AND REPLACE THE DRAG LINKS WITH A STRONGER DRAG LINK. DEALERS WILL ALSO INSPECT THE STEERING GEAR HYDRAULIC LIMIT VALVE SETTINGS. THE RECALL BEGAN ON MAY 16, 2005. OWNERS MAY CONTACT NABI AT 256-831-4296.

Defect

ON CERTAIN TRANSIT BUSES EQUIPPED WITH DETROIT DIESEL SERIES 50 ENGINES, THE TURBOCHARGER CAN FAIL ALLOWING LUBRICATING OIL TO ENTER THE EXHAUST SYSTEM.

Consequence

IN THE EVENT THE TURBOCHARGER FAILS, A FIRE MAY OCCUR IN THE ENGINE COMPARTMENT RESULTING IN PROPERTY DAMAGE OR INJURIES.

Remedy

DETROIT DIESEL IS CONDUCTING THE OWNER NOTIFICATION AND REMEDY FOR THIS CAMPAIGN. DEALERS WILL REPAIR THE ENGINE AND INSTALL AN EXHAUST TEMPERATURE SENSOR TO PREVENT THE POSSIBILITY OF AN EXHAUST OR ENGINE COMPARTMENT FIRE. OWNERS SHOULD CONTACT DETROIT DIESEL CORPORATION AT 313-592-5791 OR NABI AT 1-256-831-4296.

Defect

ON CERTAIN TRANSIT BUSES EQUIPPED WITH CUMMINS ELECTRONIC CONTROL MODULES ON THE 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.

Consequence

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 NABI AT 256-832-4296.

Defect

ON CERTAIN TRANSIT BUSES EQUIPPED WITH DIESEL OR LIQUID NATURAL GAS (LNG) FUEL SYSTEMS ONLY, IN THE AREA OF THE REAR AXLE LOWER RADIUS ROD ATTACHMENT TO THE SUSPENSION SUPPORT (OR "C" FRAME), A WELDING PROBLEM EXISTS.

Consequence

IF A CRACK WERE TO DEVELOP AND PROPAGATE AROUND THE CIRCUMFERENCE OF THE BUSHING, THE RADIUS ROD ATTACHMENT COULD BECOME LOOSE AND ALLOW MOVEMENT BETWEEN THE LOWER RADIUS ROD AND THE REAR AXLE. SHOULD THIS HAPPEN, THE REAR AXLE POSITION COULD SHIFT DURING ACCELERATION, DECELERATION, OR IN TURNS, AND COULD AFFECT THE HANDLING OF THE VEHICLE.

Remedy

OWNERS ARE BEING REQUESTED TO INSPECT THEIR BUSES FOR CRACKS AND TO REMOVE THE BUSES FROM SERVICE THAT HAVE CRACKS EXCEEDING SPECIFIC CRITERIA. NABI WILL ARRANGE TO REPAIR ALL THE VEHICLES. OWNER NOTIFICATION IS EXPECTED TO BEGIN ON DECEMBER 31, 2002. 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 NABI AT 1-888-424-5844, EXTENSION 7900.
