TRAFFIC LIGHT CHANGED, BRAKE WAS APPLIED, WENT TO FLOORBOARD, NOTHING HAPPENED. BRAKES WERE PUMPED, NOTHING HAPPENED. VEHICLE STRIKES ANOTHER VEHICLE, AIRBAG DEPLOYS, AUTOMOBILE CONTINUES IN A DITCH, POPS OUT OF THE DITCH, GOES THROUGH AN EMPTY PARKING LOT, POPS ONTO ANOTHER STREET AND EVENTUALLY STOPS AFTER GOING OVER ANOTHER CURB INTO ANOTHER PARKING LOT ABOUT 1/2 MILE FROM ACCIDENT. THEORY IS THAT ABS MALFUNCTIONED WHICH CAUSED REGULAR BRAKES TO FAIL. *JB
LOSS OF COOLANT. THE PLASTIC INTAKE PLENUM GOT A HOLE IN IT. THIS FILLED THE ENGINE WITH COOLANT THUS CAUSING THE CAR TO STALL ON THE HIGHWAY. I HAD THE DEFECTIVE PART REPLACED AT A COST OF 900 DOLLARS. I STILL HAVE THE DEFECTIVE PART. I'M RETIRED, SO THIS PUT A STRAIN ON OUR BUDGET. THANK YOU. *JB

SERVICE BULLETIN 01-06-01-007A COOLANT LEAK. IN DECEMBER 2004, MY PLASTIC INTAKE MANIFOLD MELTED AND ALLOWED THE ENGINE COOLANT TO FILL THE CYLINDERS OF THE ENGINE WITH COOLANT. GM RESOLVED THE DEFECT WITH A DESIGN CHANGE IN 99. I FEEL THAT GM IS RESPONSIBLE FOR THE COST OF THE REPAIR OF THE DEFECTIVE PART. SECOND THE ENGINE SHUT DOWN AT 55 MPH IN HEAVY TRAFFIC, WHICH IS A SERIOUS SAFETY HAZARD THAT WARRANTS A RECALL. I CONTACTED GM; SERVICE RECORD NUMBER 1-293342957 THEY NEVER CALLED ME BACK AFTER A NUMBER OF MESSAGES (7) THEN DENIED THE CLAIM. *NM

THE CHECK ENGINE LIGHT CAME ON IN MY 1998 BUICK LESABRE AND I PULLED OVER TO DISCOVER THAT THERE WAS LOW LEVELS OF COOLANT. IT HAD JUST BEEN CHECKED 2 MONTHS EARLIER AT AN OIL CHANGE AND THE WEEK BRFORE WHEN I GOT GAS. I ADDED COOLANT AND GOT BACK ON THE ROAD. AFTER 5 MILES THE CAR QUIT RUNNING IN HEAVY TRAFFIC. I HAD IT TOWED TO A BUICK DEALER WHO DIAGNOSED THE PROBLEM AS A FAILED PLENUM THAT ALLOWED COOLANT TO FOUL THE PLUGS. THE DEALER REPLACED THE PLENUM, FOULED PLUGS, COOLANT, AND OIL FOR $800.00 DOLLARS. *AK
WHILE DRIVING ENGINE LIGHT ILLUMINATED ON THE DASHBOARD CONSTANTLY. THEN, ENGINE COMPLETELY FAILED. THE GASKETS HAD BEEN CHANGED SEVERAL TIMES. ANTI-FREEZE AND OIL LEAKED. CONSUMER FOUND THAT IT WAS THE INTAKE MANIFOLD. *AK

104V090000 · Fuel System, Gasoline:delivery
Feb 24, 2004
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 3800 V6 (L36) ENGINES AND CERTAIN DELPHI FUEL PRESSURE REGULATORS, THE REGULATORS HAVE A MUCH HIGHER THAN USUAL RATE OF FUEL LEAKS. A LEAK CAN ALLOW FUEL TO ENTER THE INTAKE MANIFOLD THROUGH A VACUUM LINE. IF THE ENGINE DOES NOT START WHEN CRANKED, THE FUEL FROM THE LEAKING REGULATOR AND A MISTIMED SPARK CAN CAUSE A BACKFIRE.
Consequence & remedy
Consequence: THE BACKFIRE CAN RUPTURE THE INTAKE MANIFOLD. THE RUPTURE OF THE INTAKE MANIFOLD CAN DISPLACE A FUEL LINE, PULLING AN INJECTOR OUT OF PLACE, AND CAUSING A FUEL LEAK AND POSSIBLE FIRE.
Remedy: DEALERS WILL INSTALL NEW FUEL PRESSURE REGULATORS WITH IMPROVED DIAPHRAGMS. THE RECALL WILL BE CONDUCTED IN PHASED MAILINGS. PHASE 1 BEGAN ON JUNE 30, 2004, AND PHASE 2 BEGAN ON SEPTEMBER 30, 2004. OWNERS SHOULD CONTACT BUICK AT 1-866-608-8080, OLDSMOBILE AT 1-800-630-6537, OR PONTIAC AT 1-800-620-7668.
