Recall History (5 recalls)
FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS
ON CERTAIN HEAVY DUTY CLASS 8 DIESEL TRUCKS EQUIPPED WITH ASET AC ENGINES, THE LOCATION OF THE FUEL INLET HOSE MAY RESULT IN OVERHEATING OR ABRASION OF THE HOSE, WHICH MAY LEAD TO A PREMATURE FAILURE.
SUSPENSION
ON CERTAIN HEAVY DUTY CLASS 8 TRUCKS EQUIPPED WITH HOLLAND AIR SUSPENSION SYSTEMS, A TRANSVERSE BEAM CASTING MAY FRACTURE UNDER NORMAL LOADS. IF A CASTING BREAKS WHEN THE VEHICLE IS TRAVELING ON A ROADWAY THERE IS THE POTENTIAL FOR PIECES OF THE CASTING TO BECOME PROJECTILES AND THE SUSPENSION'S TRANSVERSE BEAM MAY DROP DOWN LOW ENOUGH TO CONTACT THE ROAD SURFACE.
FUEL SYSTEM, DIESEL
ON CERTAIN TRUCKS, A LEAK IN THE ASET AC FUEL INJECTION LINE MAY SPRAY FUEL ON THE EXHAUST GAS RECIRCULATION PIPES THAT CARRY HOT EXHAUST GASES .
FUEL SYSTEM, DIESEL
ON CERTAIN TRUCKS EQUIPPED WITH ASET AC MODEL ENGINES, THE ENGINE AS CONFIGURED WITH AN EXTERNAL EXHAUST GAS RECIRCULATION SYSTEM MAKES SERVICING THE FUEL INJECTION LINES DIFFICULT WHEN USING TRADITIONAL TOOLS. THEREFORE, IT IS POSSIBLE FOR FUEL LEAKS TO DEVELOP WHEN REMOVING AND INSTALLING THE FUEL INJECTION LINES.
