Recall History (5 recalls)

00V175000Nov 2000

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL

VEHICLE DESCRIPTION: PASSENGER VEHICLES. MANUFACTURING CHANGES WERE MADE TO THE ORVR SPRING FORCE AND FLOAT WIRE LENGTH REDUCING THE VALVE ANGLE. CERTAIN VALVES CAUSED FUEL SHUT OFF BEFORE THE TANK REACHED 95% OF NOMINAL CAPACITY.

04V305000Aug 2004

SEAT BELTS:FRONT:BUCKLE ASSEMBLY

ON CERTAIN PASSENGER AND SPORT UTILITY VEHICLES, THE FRONT SAFETY BELT BUCKLES MAY EMIT A "CLICK" SOUND DURING THE BUCKLING PROCESS THAT IS SIMILAR TO THE SOUND EMITTED WHEN A BUCKLE IS BEING LATCHED, WHEN IT IS NOT.

99V271000Nov 1999

VISIBILITY:WINDSHIELD WIPER/WASHER:LINKAGES

VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE BALL SOCKET ON THE WINDSHIELD WIPER LINK MAY BE OUT OF TOLERANCE RESULTING IN THE LINK DISENGAGING FROM THE WIPER MOTOR DRIVE UNDER LOAD, SUCH AS PUSHING AGAINST ICE, SNOW OR OTHER RESISTANCE. ALSO THE WIPER ARM RETAINING NUT COULD BE INADEQUATELY TIGHTENED ALLOWING THE WIPER ARM TO SLIP AND/OR STOP FUNCTIONING.

99V317000Dec 1999

FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP

VEHICLE DESCRIPTION: PASSENGER VEHICLES. ELECTRICAL CURRENT TO THE FUEL PUMP PASSES THROUGH THE C304 AND C305 CONNECTORS. IF EXPOSED TO MOISTURE, THESE CONNECTORS COULD CORRODE. OVER TIME, THE FUEL PUMP WILL NOT RECEIVE ENOUGH CURRENT TO OPERATE.

99V318000Dec 1999

FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP

VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE ELECTRICAL CIRCUIT FOR THE FUEL PUMP IS GROUNDED AT JUNCTION CONNECTOR G300. IF THE PIN TENSION IS POOR, OR THE BOLT SECURING THE CONNECTOR TO THE VEHICLE FLOOR IS NOT TIGHTENED SUFFICIENTLY, A POOR CONNECTION IS MADE. AS THE FUEL PUMP OPERATES, THE POOR CONNECTION CAN CREATE HEAT WHICH IN TURN INCREASES RESISTANCE. EVENTUALLY THE FUEL PUMP WILL NOT RECEIVE ENOUGH CURRENT TO OPERATE.
