MY 1999 PARK AVENUE SUDDENLY STARTED TO RUN RUFF, CAUSING ME TO TAKE THE VEHICLE TO A GM DEALER WHO REPLACED THE SPARK PLUGS AND WIRES, AS WELL AS TWO IGNITION COILS. HE STATED THAT THE PLUGS HAD INDICATION OF BURNS THAT ARE ATTRIBUTED TO ANTI FREEZE COMING IN CONTACT WITH THE PLUGS. DURING THE REPAIR HE ALSO INDICATED THAT HE NOTICED ANTI FREEZE ON THE OUTSIDE OF THE ENGINE IN THE AREA OF THE PLENUM. THE REPAIRMAN STATED THAT THIS IS A COMMON PROBLEM WITH THE 3800 MOTOR, THAT THE PLENUM LEAKS CAUSING ASSOCIATED PROBLEMS DUE TO THE ANTI FREEZE COMING IN CONTACT WITH ENGINE COMPONENTS. HE ALSO STATED THAT THIS PROBLEM CAN LEAD TO ENGINE FAILURE IF NOT CORRECTED BY REPLACEMENT OF THE PLENUM AND THE INTAKE GASKET. *TR

PLASTIC INTAKE MANIFOLD FAILURE OCCURRED ON 1999 BUICK PARK AVENUE WITH APPROXIMATELY 45,000 MILES. COOLANT LEAKED INTO THE ENGINE AND RESULTED IN A MISFIRE CODE IN MULTIPLE CYLINDERS. SYMPTOMS EXPERIENCED BY THE DRIVER WERE A ROUGH IDLE AT START FOR 30 SECONDS, AND THE SERVICE ENGINE SOON LIGHT WOULD COME ON, SOMETIMES STAYING ON AND SOMETIMES EXTINGUISHING AFTER 15 SECONDS. THE CAR WAS IMMEDIATELY DRIVEN FOR SERVICE. THE DEALER INITIALLY DIAGNOSED THE PROBLEM AS A COMBINATION OF DIRTY FUEL INJECTION SYSTEM (CLEANED REGULARLY, BUT STILL NEEDED TO BE CLEANED AGAIN TO CONVINCE DEALER TO RULE OUT THIS PROBLEM). WHEN PROBLEM PERSISTED IN CYLINDER #6, THE PROBLEM WAS THEN DIAGNOSED AS A FAULTY FUEL INJECTOR WHICH WAS REPLACED. WHEN THE PROBLEM PERSISTED, IT WAS NOTICED THAT COOLANT HAD GOTTEN INTO CYLINDER #6 IN SMALL AMOUNTS AND CAUSE A MISFIRE. DEALER THEN DIAGNOSED PROBLEM AS THE PLASTIC INTAKE MANIFOLD. WEB SEARCHING REVEALS THAT THIS IS A CHRONIC PROBLEM AS THE DESIGN WAS CHANGED FROM METAL TO PLASTIC. HOWEVER, THERE ARE NO CURRENT RECALLS ON THIS ISSUE. COST TO REPAIR IS APPROXIMATELY $1,700. *TR

CAR STALLS FOR NO REASON .WHEN IT STALLS NO CHECK ENGINE LIGHT COMES ON OR MESSAGES INDICATEING WHAT THE FAILURE WAS. THE CHECK ENGINE LIGHT DOES APPEAR BEFORE YOU START YOUR VECHICLE BUT WHEN CAR STALLS THE ENGINE LIGHT DOES NOT COME ON. IT IS RISK TO BE DRIVING THE VEHICLE AND HAVING THE ENGINE STALL AND NOT REALIZING IT .IT ENDANGERS THE LIVES OF THE PERSONS NOT ONLY IN THE VEHICLE BUT OTHERS AS WELL. DEALER HAS TRIED TO REPAIR SEVERAL TIMES BUT THE THE CHECK ENGINE LIGHT STILL DOES NOT ILLUMINATE.I BELIEVE THAT THIS IS AN ENGINEERING PROBLEM IN WHICH THE VEHICLE WAS NEVER PROGRAMMED TO ILLUMINATE THE CHECK ENGINE LIGHT ANYWAYS.

WHILE DRIVING VEHICLE LOST POWER ON THE HIGHWAY. DEALER WAS CONTACTED. *AK

AFTER VEHICLE HAS BEEN PARKED IN HEATED GARAGE FOR AWHILE. THEN STARTED IT, AND VEHICLE STALLED. WOULD NEED TO BE JUMPED. HAS HAPPENED 15 TIMES. TOOK VEHICLE TO DEALERSHIP & MECHANIC CHANGED THE BATTERY & ALTERNATOR. BUT PROBLEM COULD NOT BE DUPLICATED. *AK

THE VEHICLE DOES NOT ALWAYS ACCELERATE WHEN I STEP ON THE GAS PEDAL. THIS CAN BE DANGEROUS WHEN I AM TRYING TO PULL OUT INTO TRAFFIC. BUICK KNOWS ABOUT THE PROBLEM BUT HAS BASICALLY TRIED TO PRETEND THAT IT DOES NOT EXIST.
