AT 55MPH, FUEL LINE SNAPPED, CAUSING FLUID TO LEAK ONTO THE MOTOR. CAUSE UNKNOWN. DEALER NOTIFIED.*AK THE PLASTIC CONNECTORS AT THE MOTOR MANIFOLD BROKE OFF. DEALER WAS NOTIFIED BUT NO CALL WAS RETURNED TO CONSUMER. THE STEEL TUBING FROM THE GAS TANK IS CONNECTED TO THE STEEL MANIFOLD AT THE MOTOR BLOCK WITH A THIN WALLED PLASTIC TUBING. UNDER THE VEHICLE, THE PLASTIC TUBING IS HEAT-SHRUNK TO THE STEEL TUBING IN WHICH NO FITTINGS ARE USED. AT THE MOTOR MANIFOLD, PLASTIC FITTINGS ARE USED. THE FITTING BROKE, AND FUEL WAS SPILLING ONTO THE HOT MOTOR BLOCK AND FORMED A PUDDLE OF HOT FUEL, ONE PERSON INHALED THE GAS FUMES. *JG

WHEN CONSUMER STARTED VEHICLE THERE WAS A LOUD BANG THAT CAME FROM FRONT OF VEHICLE. SMOKE STARTED COMING FROM UNDERNEATH HOOD, AND THE VEHICLE WAS ON FIRE. THE CAUSE OF THIS DEFECT WAS THAT THE FUEL DID NOT GO INTO FUEL RELAY SYSTEM, AND INJECTOR SPRAYED FUEL BACKWARDS ONTO INTAKE MANIFOLD WHICH IGNITED THE FUEL. THIS HAPPENED ONCE BEFORE JULY 28, 2000 AND AGAIN ON MAY 13, 2001. *AK *JB

VEHICLE WOULD NOT START. TOOK VEHICLE TO AN INDEPENDENT MECHANIC WHO FOUND FUEL PUMP AND FUEL SENDING UNIT NEEDED TO BE REPLACED. *AK THERE WAS ELECTRICAL PROBLEM WITH THE FUEL PUMP. *YH

VEHICLE WON'T BE ABLE TO CRANK AT THE TIME, AND NO ELECTRICAL FUNCTION. VEHICLE HAD TO BE TOWED TO TECHNICIAN, AND HE SAID THAT FUEL PUMP HAD MELTED INSIDE OF FUEL TANK. WHEN A PART MELTS LIKE THAT IT JUST MAKES SPARKS.*AK

CAR FAILS TO ACCELERATE PAST 30MPH UNDER NORMAL DRIVING CONDITIONS. INCREASING PRESSURE ON GAS PEDAL AT 30MPH YIELDS NO RESPONSE FROM CAR. WHEN CAR HITS PASSING GEAR, FINALLY ACCELERATES PAST 30MPH. IN ADDITION, AT INTERSTATE SPEEDS IE. 70-75 MPH CAR DEVELOPS ALMOST A STUTTER AND CANNOT MAINTAIN SPEED AND STARTS TO DECELERATE. BOTH PROBLEMS OCCUR IN BOTH DRIVE AND OVERDRIVE. HAS BEEN IN FOR REPAIRS TO 4 DIFFERENT REPAIR SHOPS, 2 OF THEM AUTHORIZED BUICK DEALERS. THEY HAVE REPLACED THROTTLE POSITION SENSOR, CLEANED FUEL INJECTORS, NEW FUEL PUMP AND FUEL FILTER, NEW KNOCK SENSOR AND BLOWN CARBON OUT OF ENGINE TWICE.
