5/15/2017, $1,197.66 REPAIR FOR INTAKE MANIFOLD GASKET. ON OCTOBER 23, 2008, THE CALIFORNIA SUPERIOR COURT GRANTED FINAL APPROVAL TO THE CLASS ACTION LAWSUIT, BUT NOTHING IS AVAILABLE TO THOSE OF USE THAT DID NOT HAVE A PROBLEM UNTIL AFTER THAT SUIT. HTTPS://WWW.GIRARDGIBBS.COM/DEXCOOL/
TL* THE CONTACT OWNS A 2001 BUICK CENTURY. WHILE DRIVING APPROXIMATELY 35 MPH, THE VEHICLE STALLED. THE VEHICLE WAS ABLE TO BE RESTARTED, BUT THE FAILURE RECURRED MULTIPLE TIMES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO COULD NOT DETERMINE THE CAUSE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 200,000.
TL* THE CONTACT OWNS A 2001 BUICK CENTURY. THE CONTACT STATED THAT THE VEHICLE OVERHEATED AND THE TEMPERATURE WARNING LIGHT ILLUMINATED. THE CONTACT INSPECTED THE OIL LEVEL AND DISCOVERED THAT THE ANTI FREEZE WAS LEAKING INTO THE OIL. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC WHERE IT WAS DIAGNOSED THAT THE LOWER GASKET INTAKE SET FAILED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 144,900 AND THE CURRENT MILEAGE WAS 144,950.

TL*THE CONTACT OWNS A 2001 BUICK CENTURY. WHILE THE VEHICLE WAS UNDERGOING AN OIL CHANGE, THE CONTACT WAS INFORMED THAT DEXCOOL COOLANT WAS PLACED IN THE WATER TANK INSTEAD OF ANTIFREEZE. THE MANIFOLD ON THE WATER BLOCK, WHICH IS THE GASKET BETWEEN THE WATER TANK, DID NOT HAVE THE CORRECT TYPE OF GASKET AND DETERIORATED THE WATER DUE TO OIL IN THE TANK. THE FAILURE IS CALLED A "PINK MILKSHAKE". THIS ALSO OCCURS WHEN THERE IS OIL IN THE WATER RESERVOIR. THE REPAIR WOULD COST $800. THE VIN WAS UNKNOWN. THE FAILURE MILEAGE WAS 38,000.
LEAKING INTAKE MANIFOLD. *TR
TAPPETS SOUND ON A 2001 BUICK CENTURY TAPPETS WERE REPLACED TWICE UNTIL I WAS INFORMED THAT ALL GM 2001 CARS HAD THIS DEFECT. IT SEEMS THAT OIL IS NOT GETTING TO THE CENTER CYLINDERS, BECAUSE THE CONNECTING FEEDS ARE TOO SMALL. PROBLEM THAT CAN DEVELOP IS THE ENGINE CAN SEIZE. *TR
TL*THE CONTACT OWNS A 2001 BUICK CENTURY. THE VEHICLE'S INTAKE MANIFOLD GASKET FAILED AT LESS THAN 100,000 MILES ON A BRAND NEW ENGINE. THE CONTACT SMELLED ANTI-FREEZE AND BROUGHT THE VEHICLE TO A MECHANIC WHO CONDUCTED PRESSURE TESTING. THE FAILURE WAS DIAGNOSED AS THE MANIFOLD GASKET. IT IS A REPLACEMENT ENGINE AND IT IS DEMONSTRATING THE SAME FAILURE AS THE ORIGINAL ENGINE THAT WAS REPLACED AT 35,000 MILES BY ARBITRATION ORDER. BUICK HAS REFUSED TO PAY FOR ANY FAILED COMPONENTS CONCERNING THIS MOTOR, INCLUDING REPLACING THE CATALYTIC CONVERTER. THE CONVERTER WAS PLUGGED FROM THE ORIGINAL MOTOR FAILURE ALONG WITH THE SUBSEQUENT FAILURE FROM THE INTAKE MANIFOLD GASKET ON THE NEW MOTOR. THE POWER WINDOW REGULATOR FAILED IN JANUARY OF 2007 FOR THE SECOND TIME. THE CURRENT MILEAGE IS 145,000 AND FAILURE MILEAGE WAS 100,000.
INTAKE MANIFOLD GASKET LEAK. *JB
CAR HEATER WOULD NOT WARM UP. TEMPERATURE WOULD THEN FLUXUATE BETWEEN HOT AND COLD. TOOK THE CAR TO THE DEALERSHIP, THE DEALERSHIP DIAGNOSED THE PROBLEM AS INTAKE MANIFOLD GASKET FAILURE. COOLANT MIXED IN WITH OIL IN THE ENGINE. DEALERSHIP SERVICE DEPARTMENT REQUIRED TO KEEP CAR OVERNIGHT TO FIX THE PROBLEM. NEEDED A RENTAL CAR AND NO LOANER WAS AVAILABLE. GM AGREED TO SPLIT THE COST OF THE INTAKE MANIFOLD GASKET REPAIR 50/50, BUT WOULD NOT COVER THE COST OF A RENTAL CAR. EFFECT OF THIS GASKET FAILURE AT THIS TIME IS UNKNOWN AND EFFECT TO ENGINE AND COMPONENTS. CAR HAS 68,500 MILES. ORIGINAL OWNER OFF CAR HAS KEPT UP WITH ALL SCHEDULEED MAINTENANCE. *NM
MANIFOLD GASKET NEEDS TO BE REPLACED DUE TO A SMALL LEAK WHICH IS CAUSING CONSIDERABLE AMOUNT OF PROBLEMS. ALL MECHANICS THAT I HAVE TAKEN THIS CAR TO SAY THERE IS A PROBLEM WITH THIS PARTICULAR ENGINE WHERE GM CHANGED TO PLASTIC GASKET. ALL SEEM TO HAVE SAME DIAGNOSES EXCEPT GM AND GM DEALERSHIP. *JB
THE CONSUMER'S 2001 BUICK CENTURY STALLS WHEN SLOWING DOWN TO MAKE A TURN. *TS *NM
2001 BUICK CENTURY ENGINE PISTON CRACKED DAMAGING THE CYLINDER WALL. *TS ***NO ANSWER REQUIRED*** *JB
CONSUMER 2001 BUICK CENTURY ELECTRICAL AND COOLING ARE DEFECTIVE. MASTER WINDOW SWITCH LOCK STUCK, ANTI FREEZE LEAK, COOLANT LIGHT REMAINS ON, FRONT AND REAR LIGHTS DO NOT WORK. *TS THE DOME LIGHTS AND BACK UP LIGHTS, AND TAG LIGHT WERE ALL INOPERATIVE. THE CONSUMER STATED ALL THE BULBS WERE CHANGED, HOWEVER IT DIDN'T RESOLVE THE PROBLEM. THE INTAKE GASKET LEAKED. *JB
THE TEMPERATURE LIGHT CAME ON AND THE GAUGE READ HOT ON MY 2001 BUICK CENTURY AT THE BEGINNING OF A 200 MILE TRIP. I TOOK THE NEXT EXIT, FOUND A STATION WITH A MECHANIC AND ASKED TO HAVE HIM CHECK THE WATER LEVEL IN THE RADIATOR. HE SAID THE BUICK CENTURY HAS A HISTORY OF THIS PARTICULAR PROBLEM AND ADVISED THAT I WATCH THE TEMPERATURE GAUGE AND TAKE THE CAR TO THE DEALER UPON MY RETURN HOME. WHEN I ARRIVED AT MY DESTINATION, MY SON INFORMED ME THAT HE HAD THE SAME PROBLEM WITH HIS WIFE'S 1999 BUICK CENTURY, ADDED A SEALANT TO THE RADIATOR AND IT SEEMED FINE. WHEN I GOT HOME AND TOOK THE CAR TO THE DEALER TO HAVE THE RADIATOR CHECKED, THE SERVICE MANAGER IMMEDIATELY INFORMED ME THAT THE PROBLEM WAS PROBABLY NOT THE RADIATOR AND THAT THE UPPER PORTION OF THE ENGINE WOULD HAVE TO BE REMOVED TO THE TUNE OF APPROXIMATELY $700. SIX HOURS LATER HE CALLED TO INFORM ME THAT THE PROBLEM WAS THE INTAKE GASKET AND THE REPAIRS WERE ONLY $648.52. PARTS REPLACED INCLUDED: GASKET KIT, GASKET, SEALER-THE(?), SEAL, SEAL, COOLANT, ADHESIVE, SEAL, ENG., THERMOSTAT (?), GASKET (191.84) LABOR: 428.75. I RECEIVED A CALL FROM MY SON TONIGHT TO ADVISE ME THAT HIS '99 CENTURY WAS "STEAMING" AND WAS TOLD BY HIS MECHANIC THAT PROBLEM WAS THE INTAKE MANIFOLD. REPAIRS APPROXIMATELY $800. *JB
DEFECTIVE ELECTRICAL MASTER LOCK UNIT: LEFT FRONT DOOR. ANTI FREEZE LEAKS, COOLANT LIGHT STAYS ON, LIGHTS ARE DEFECTIVE ETC. *TS THE FRONT AND REAR TURN SIGNALS, BRAKE LIGHTS, DOME LIGHTS, BACK UP LIGHTS AND TAG PLATE LIGHT WERE ALL INOPERATIVE. *JB
THE TEFLON SCRAPED OFF, ALONG WITH STUMBLING AND HESITATION. THE ENGINE WAS REPLACED. UPON THE REPLACEMENT OF THE CATALYTIC CONVERTER, METAL SHAVINGS WERE FOUND IN THE FRONT SCREEN. THE NEW CATALYTIC CONVERTER REMOVED ALL OF THE STUMBLING AND HESITATION. THE OLD CATALYTIC CONVERTER SHOWED EVIDENCE OF ANTIFREEZE AND WAS DEFECTIVE AT TIME OF THE NEW ENGINE REPLACEMENT UNDER FACTORY WARRANTY. A NEW CATALYTIC CONVERTER SHOULD HAVE BEEN INSTALLED AT THE TIME OF THE ENGINE REPLACEMENT. THE DEFECTIVE ENGINE DEBRIS AND OBVIOUS HEAD GASKET LEAK CONTRIBUTED TO THE CATALYTIC CONVERTER FAILURE. GENERAL MOTORS SHOULD PAY FOR REPLACEMENT OF THEIR POORLY DIAGNOSED CATALYTIC CONVERTER, PLACE IN USED SPARK PLUGS AND WIRES. GENERAL MOTORS WOULD NOT GIVE A 100,000 MILE WARRANTY FOR THE NEW ENGINE. *AK THE CHASSIS MILEAGE WAS 94K MILES. *SC
ABOUT A MONTH AGO THE CHECK ENGINE LIGHT CAME ON. BECAUSE OF THE COST TO HAVE A MECHANIC HOOK UP THE OBDII MONITOR I DIDN'T TAKE THE VEHICLE IN RIGHT AWAY, HOPING IT WAS SIMPLY DUE TO A DIRTY SENSOR OR LOOSE GAS CAP (WHICH HAS BEEN THE ROOT CAUSE BEFORE IN OTHER VEHICLES). SHORTLY AFTER THE CHECK ENGINE LIGHT INCIDENT THE TEMP GAGE AND HEATER STARTED ACTING FUNNY. STARTING IN THE MORNING THE HEATER ONLY PROVIDED LUKEWARM AIR AT BEST. THEN THE TEMP GAUGE WOULD SPIKE REALLY FAST AND THE COOLANT ALARM WOULD COME ON. THEN RIGHT AWAY THE GAGE WOULD NORMALIZE AND THERE WOULD BE NO PROBLEMS THE REST OF THE TRIP. THE TEMP GAGE WOULD BE IN THE NORMAL RANGE. THE PROBLEM ONLY HAPPENED A COUPLE OF TIMES THEN APPEARED TO GO AWAY. YESTERDAY THE PROBLEM RE-SURFACED EXCEPT THE TEMP GAUGE DIDN'T NORMALIZE AND THERE WAS A SMELL OF ANTIFREEZE COMING FROM THE ENGINE COMPARTMENT. AFTER CALLING AROUND TO MECHANICS IT SOUNDS LIKE IT COULD BE THE INTAKE GASKET. SINCE THE BEGINNING OF THESE PROBLEMS I'VE BEEN CHECKING THE COOLANT. I OWN OTHER GM VEHICLES SO I'M FAMILIAR WITH INTAKE MANIFOLD GASKET FAILURES. IN FACT, I HAD TO REPLACE THE INTAKE MANIFOLD GASKET ON OUR BLAZER ABOUT 1 MONTH AGO. THIS BUICK ONLY HAS ABOUT 40K MILES ON IT. I THOUGHT BUICK WAS GM'S "QUALITY" DIVISION????*AK
THE 2001 BUICK CENTURY WAS NOT SHIFTING WELL AND RAN OUT OF TRANSMISSION FLUID. WHEN THE RESERVOIR FOR TRANSMISSION FLUID WAS REFILLED THE FLUID RAN OUT QUICKLY AND I TOOK THE CAR INTO THE LOCAL DEALER TO BE REPAIRED. THEY TOLD ME ALL THE FLUIDS WERE MIXING AND THAT IF IT WAS NOT FIXED THE ANTIFREZE AND WATER WOULD HAVE LEAKED INTO THE OIL AND BLEW THE MOTOR BECAUSE THE LOWER INTAKE MANIFORLD GASKET WAS BAD. THE BILL FROM THE DEALER ACCOUNTS FOR LEAKING TRANSMISSION FLUID LINES AND THE LI MANIFOLD GASKET. THESE WERE EXPENSIVE REPAIRS AND THE REASON I DECIDED TO REPORT THEM WAS THAT MY SON AND DAUGHTER-INLAW BOTH HAVE NEW GM VEHICLES AND HAVE REPLACED THE INTAKE MANIFOLD GASKETS ON ONE OF THEM 2 TIMES AND THE OTHER 1 TIME FOR A TOTAL OF 4 INTAKE MANIFOLD GASKETS FOR OUT FAMILY. THEY HAVE A 2001 AND A 2002 ALERO. NOW MY DAUGHTER IS ALSO DESCRIBING WHAT MAY BE THE SAME PROBLEM.*AK
WHILE DRIVING 60 MPH THE LOW COOLANT SENSOR LIGHT CAME ON. THE CONSUMER BROUGHT THE VEHICLE TO THE REPAIR SHOP WHERE THEY STATES THE INTAKE MANIFOLD GASKET HAD MALFUNCTIONED. PLEASE PROVIDE ADDITIONAL INFORMATION. *NM *TC
OUR WELL MAINTAINED 2001 BUICK CENTURY WITH A 3.1 L V6 HAS DEVELOPED AN INTAKE MANIOLD LEAK AT UNDER 75,000 MILES. THE CAR HAS BEEN WONDERFUL SINCE PURCHASED NEW - UNTIL NOW. INTERNET RESEARCH HAS REVEALED THAT GM USED A "PLASTIC" INTAKE MANIFOLD AND IT HAS BEEN PROBLEMATIC. IT WAS ALSO REVEALED THROUGH RESEARCH INTO GASKET MANUFACTURERS THAT THE 100,000 COOLANT IS MORE CORROSIVE THAT GM ANTICIPATED. NOW, WHERE DOES THE RESPONSIBILITY LIE FOR THE MANUFACTURER (BUICK DIV) TO TAKE OWNERSHIP AS A RESPONSIBLE CORPORATE CITIZEN AND PROVIDE SOME REPLACEMENT COST RELIEF TO THE CUSTOMER? I CURRENTLY OWN 3 GENERAL MOTORS VEHICLES, HOWEVER ONLY 1 WITH THE PROBLEMATIC INTAKE MANIFOLD DESIGN. I LOOK FORWARD TO HEARING FROM SOMEONE SOON. AS A MARKETING MANAGER FOR A MAJOR COMPANY, I CAN ASSURE GM THAT CUSTOMER LOYALTY IS WHAT DRIVES MY BUSINESS SUCCESS. IN ORDER FOR ME TO SELECT GM FOR MY NEXT VEHICLE, I WOULD LIKE THEM TO TELL ME WHAT THEY WILL DO TO REMEDY THIS DESIGN FLAW PROBLEM OF INTAKE MANIFOLD GASKET FAILURE. THANKS, ART PANDARU. *AK
WHILE DRIVING, THE CONSUMER WOULD SMELL SULFUR INSIDE THE VEHICLE. THE DEALERSHIP WAS NOTIFIED, BUT DID NOT RESOLVE THE PROBLEM. PLEASE PROVIDE MORE INFORMATION.
VEHICLE MAKES NOISES UPON START UP THEN VEHICLE DIES. *MR
CONSUMER STATED VEHICLE STALLED WHILE DRIVING 5 MPH, THE ENGINE WAS REPLACED UNDER WARRANTY, HOWEVER AT 3000 MILES THE VEHICLE EXPERIENCED ENGINE PROBLEMS AGAIN AND WAS RETURNED TO THE DEALERSHIP FOR ADDITIONAL REPAIRS.*JB
CONSUMER STATES THAT THE VEHICLE WOULD INTERMITTENTLY BACKFIRED AND STALLS UPON STARTING. DEALER NOTIFIED. *AK THE ENGINE WAS REPLACED BY THE MANUFACTURER UNDER BULLETIN TEFLON COATING FAILURE. THE STARTING AND STALLING PROBLEM REOCCURED AFTER 3000 MILES, BUT THE DEALER REFUSED TO HONOR THE WARRANTY. THE WATER PUMP FAILED. ALSO, THE STEERING COLUMN FLEXES WHEN THE VEHICLES MOVEMENT WAS REDUCED. *YH
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
