NHTSA ODI complaints, all model years
Recalls
7 campaigns cover the 4000.
THE DIFFERENTIAL OIL OF THE TRANSAXLE IS LOST OVER TIME DUE TO EVAPORATION. LOW OIL LEVELS CAUSE PREMATURE BEARING AND GEAR WEAR AND EVENTUAL FAILURE OF THE DIFFERENTIAL.
EXCESSIVE WEAR OF IDLE STABILIZER COULD CAUSE IDLE FLUCTUATIONS.
REAR OR FRONT RIGHT SEAT BELT LOCKS MAY NOT PROPERLY ENGAGE. CONSEQUENCE OF DEFECT: SEAT BELTS COULD SEPARATE IN EVENT OF HEAVY BRAKE APPLICATION OR IMPACT AND THUS SUBJECT PASSENGERS TO INJURY.
UNDER ADVERSE WEATHER CONDITIONS, OUTER RUBBER LAYER OF BRAKE HOSES MAY BECOME BRITTLE AND DEVELOP CRACKS. CONSEQUENCE OF DEFECT: CRACKS COULD LEAD TO LOSS OF BRAKE FLUID RESULTING IN AN INCREASE IN STOPPING DISTANCE AND POSSIBLY AN ACCIDENT.
THE FUEL PUMP MAY STOP FUNCTIONING WITHOUT WARNING. THIS CAN OCCUR BECAUSE AN ELECTRICAL CONNECTOR IN THE FUSE PANEL MAY OVERHEAT AND INTERRUPT THE ELECTRICAL CIRCUIT.
REAR BUMPER SYSTEM ON CERTAIN VEHICLES MAY NOT HAVE BEEN PROPERLY WELDED DURING ASSEMBLY. IN THE EVENT OF A REAR END COLLISION, THE RIGHT SIDE BUMPER SUPPORTOR COULD BREAK LOOSE, DAMAGE THE FUEL TANK AND ALLOW FUEL TO LEAK.
ON CERTAIN VEHICLES, POROUS SPOTS MAY HAVE DEVELOPED ON THE INTERIOR SURFACE OF THE THREADED HOLE FOR THE BRAKE HOSE DURING THE MOULDING PROCESS. THESE SPOTS ALLOW BRAKE FLUID TO SEEP FROM THE CALIPERS DURING HEAVY BRAKE APPLICATIONS.
