MY CAR IS NOTHING BUT A PROBLEM AND VERY SERIOUS PROBLEM. I LOST CONTROL OF MY CAR AND ALMOST GET INTO ACCIDENT. THE ABS BREAKS IS NOT STABLE,SO MANY ELECTRICAL PROBLEMS. POWER WINDOWS IS DEFECT.
I HAD TO REPLACE THE HEAD GASKET TWICE. MECHANIC INDICATED THE FIRST TIME THAT THE COOLANT MIGHT BE THE CAUSE FOR THE GASKET DETERIORATION. WHEN REPLACED THE SECOND TIME, THE GASKET WAS (I BELIEVE) A METAL RATHER THAN PLASTIC OR RUBBER AND THE COOLANT WAS GREEN. SO FAR, SO GOOD. BOTH REPLACEMENTS COST $1000+. RECENTLY HAD BRAKES REPLACED AND WAS TOLD THE INTAKE MANIFOLD GASKET NEEDS TO BE REPLACED AT A COST OF $1100. THE CAR RUNS WELL, BUT HAS SERIOUS RUST ON THE RAIL BELOW THE DOORS. NOT SURE I SHOULD SPEND THAT MUCH ON A 16 YR OLD CAR. I'VE ALSO HAD TO HAVE A MOTOR ON THE DRIVER'S SIDE WINDOW REPAIRED. THAT SEEMS TO BE A FREQUENT PROBLEM WITH THIS MODEL, TOO.
TL* THE CONTACT OWNS A 1999 BUICK CENTURY. WHILE DRIVING 5 MPH, THE ENGINE STALLED. THE CONTACT PLACED THE VEHICLE IN NEUTRAL AND RESTARTED THE IGNITION, BUT THE FAILURE RECURRED NUMEROUS TIMES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 98,400. UPDATED 10/07/14*LJ UPDATED 3/24/2015 *JS
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
AS THE 3RD OWNER OF A 1999 BUICK CENTURY LIMITED I DID A THOROUGH SEARCH OF CARS HISTORY AND FOUND NO PROBLEMS UNTIL TODAY 8 9 2013 WHEN I TOOK IT IN FOR RADIATOR HOSE CHANGE COOLING SYSTEM FLUSH AND OIL CHANGE WHICH LATER WAS TOLD ALLTHEY COULD DO WAS THE TRANNY FLUSH BECAUSE OF THE INTAKE MANIFOLD GASKET LEAK WHICH IM HEARING IS A HUGE 3.1 GM ENGINE PROBLEM. UPPON CALLING THE FORMER OWNER SHE INFORMED ME THAT AT 50,000 IT WAS REPLACED AND AGAIN AT 108,765 MILES. IT NOW HAS 137549 MILES AND IY HAS AGAIN TAKEN A DUMP I HEAR A COOLANT TYPE CONVERSION CAN HELP MY $700.00 PROBLEM. IM OUTRAGED THAT A CAR IN THIS GOOD OF CARE IS A BIG DISASTER. RECALL IS NEEDED & I SHOULDA KEPT MY 92 CENTURY WITH THE 3.3 V6 IT HAD 374,988 MILES AT TRADE IN & STILL RAN AWESOME:{ IM SO UNHAPPY WITH THIS CAR I AM READY TO FIX IT AND TRADE IT OFF FOR A FORD LOL. *TR
CPSC# I1280196A. 1999 BUICK CENTURY. CONSUMER GOT AN ENGINE FOR HIS CAR. *LN THE CONSUMER STATED THE VERY DAY HE PURCHASED THE ENGINE AND HAD IT INSTALLED, THE ENGINE LIGHT ILLUMINATED. THE ENGINE WAS TESTED AND THE CONSUMER WAS INFORMED, THE PROBLEM WAS WITH THE EGR VALVE. THE CONSUMER PURCHASED THE EGR VALVE. HOWEVER, THE ENGINE LIGHT REMAINED ON. THE TECHNICIAN WHO INSTALLED THE ENGINE, STATED THE CYLINDER HEADS WERE DAMAGED. *JB
TL*THE CONTACT OWNS A 1999 BUICK CENTURY. WHILE DRIVING APPROXIMATELY 55 MPH, THE TEMPERATURE GAUGE INCREASED AND THE CONTACT BEGAN TO SMELL BURNING ANTIFREEZE. THE CONTACT PARKED THE VEHICLE AND A MECHANIC STATED THAT THE INTAKE GASKET WAS LEAKING COOLANT AND NEEDED TO BE REPLACED. THE CURRENT AND FAILURE MILEAGES WERE 54,310.
PASSENGER AIRBAG LIGHT ON--MEANS AIRBAG WILL NOT/MAY NOT DEPLOY IF IN AN AUTO ACCIDENT. DEALER SHARPE BUICK REPLACED MODULE APPROX 3 TIMES BUT PROBLEM STILL EXISTS. I WAS TOLD THAT AIRBAG LIGHT HAD TO STAY ON CONSTANT BEFORE THEY COULD DO ANYTHING, LIGHT IS ALWAYS ON AND PROBLEM WAS STILL NOT RESOLVED. ALSO ANTIFREEZE LEAKING DUE TO LEAKING LOWER INTAKE GASKET WHICH HAS BEEN LEAKING FOR YEARS ALSO TAKEN TO SHARPE BUICK SEVERAL TIMES THEY DIDN'T SEE A PROBLEM EVEN WHEN THERE WAS A SMELL AT THE DEALERSHIP. ALSO THE INSTRUMENT PANEL CLUSTER WAS REPLACED IT STARTING DIMMING AND FINALLY WENT BLACK. I HAVE RECENTLY PAID FOR THESE REPAIRS. CAR CAME WITH MANUFACTURER WARRANTY WHEN I PURCHASED THE CAR AND I ALSO PURCHASED AN EXTENSION ON THE MANUFACTURER WARRANTY FROM THE CAR DEALER SIEF CHEVY/BUICK IN HASTINGS MI WHERE I PURCHASED THE CAR. *TR
BOTH THE INTAKE MANIFOLD AND THE HEATER CORE FAILED ON MY CAR. *TR
SECOND FAILURE OF INTAKE MANIFOLD GASKET ON 1999 BUICK CENTURY 3.1 M ENGINE. CAUSES ANTI FREEZE TO LEAK FROM MANIFOLD WHICH COULD CAUSE A FIRE (AS STATED IN OWNERS MANUAL, WARNING NOT TO SPILL ANTI-FREEZE ON A HOT ENGINE WHEN FILLING RADIATOR AS IT COULD CAUSE A FIRE). FIRST FAILURE OCCURRED AT 72,000 MILES. SECOND FAILURE AT 115,000 MILES. *JB
NOTICE COOLANT IS LEAKING AROUND THE INTAKE MANIFOLD AREA ON 3.1L V6 ENGINE OF MY 1999 BUICK CENTURY. LOCAL MECHANIC SAID IT WAS A COMMON PROBLEM WITH THIS ENGINE. DEALER IS ASKING APPROXIMATELY $900.00 TO REPAIR THIS PROBLEM. THIS SHOULD BE A RECALL ON THIS ENGINE IF THIS IS A FREQUENT PROBLEM. A GOOD ENGINE SHOULD NOT FAILED LIKE THIS IN MY OPINION. THIS IS NOT A NORMAL WEAR AND TEAR OF THE ENGINE, BUT POOR ENGINEERING OF THE ENGINE. DEALER SHOULD PAY FOR THIS PROBLEM. *JB
DT*: THE CONTACT STATED THE ENGINE'S INTAKE MANIFOLD WAS LEAKING ANTIFREEZE. THE NON SERVICE DEALER DETERMINED THE TOP OF THE MOTOR NEEDED TO BE REPLACED. THE VEHICLE WAS NOT TAKEN TO A SERVICE DEALER
DT*: THE CONTACT STATED WHEN THE VEHICLE WAS AT THE DEALERSHIP FOR A ROUTINE BRAKE CHECK, IT WAS NOTICED THAT ANTIFREEZE HAD LEAKED INTO THE ENGINE. THE MECHANIC INFORMED THE CONTACT THERE WERE MANY PEOPLE WITH THIS PROBLEM. THE CONTACT STATED THERE WERE NO PROBLEMS WITH THE VEHICLE PRIOR TO THE INCIDENT.
DT*: THE CONTACT STATED WHILE TRAVELING 20 MPH THE VEHICLE STALLED. NO WARNING LIGHTS ILLUMINATED PRIOR TO THE FAILURE. THE VEHICLE WAS TOWED TO THE DEALER WHERE IT WAS DETERMINED TO HAVE A FAULTY CAM SHAFT. THE CONTACT WAS INFORMED THAT THE ENGINE NEEDED TO BE REPLACED.
I AM THE OWNER OF A 1999 BUICK CENTURY WITH 78,000 MILES. I BOUGHT THE VEHICLE USED AND HAVE NO CURRENT WARRANTY. RECENTLY, THE LOW COOLANT DASH LIGHT BEGAN TO INTERMITTENTLY ILLUMINATE, WHICH PROMPTED ME TO CHECK THEE COOLANT LEVEL AND SEARCH THE UNDERNEATH OF MY VEHICLE. THE COOLANT LEVEL WAS NOT LOW; HOWEVER, THERE WAS A SMALL AMOUNT OF COOLANT ON THE GROUND. I DID EXTENSIVE RESEARCH ON THE INTERNET AND IDENTIFIED THAT TENS OF THOUSANDS OF GM VEHICLE OWNERS HAVE HAD THIS SAME PROBLEM WITH THE COOLANT SYSTEMS IN THEIR GM VEHICLES. THE PROBLEM WAS THAT THE LOWER INTAKE MANIFOLD GASKET NEEDED TO BE REPLACED. GM CLAIMS THAT THE DEX COOL COOLANT, WHICH IS REQUIRED IN THEIR VEHICLES, LASTS FOR 150,000 MILES OF VEHICLE USE WITHOUT NEEDING TO BE CHANGED. HOWEVER, MY INTERNET RESEARCH OF OTHERS'' COMPLAINTS, AND THE SERVICE REPAIRMAN AT MY LOCAL GARAGE, CONFIRMED THAT THE DEX COOL COOLANT THROUGH THE LOWER GASKET AT APPROXIMATELY 70-80,000 MILES, REQUIRING A NEW LOWER INTAKE MANIFOLD GASKET AND A COOLANT FLUSH, AS WELL AS A NECESSARY OIL CHANGE BECAUSE THE COOLANT LEAKS INTO THE OIL DUE TO THE FAULTY GASKETS (AND IN TURN CAUSES DECREASED LUBRICATION IN THE ENGINE AND RUINS THE BEARINGS WHICH IS ALSO A COSTLY PROBLEM.) AFTER HAVING MY VEHICLE REPAIRED FOR $900, I AM TOLD BY MY SERVICE REPAIRMAN THAT THIS PROBLEM WILL OCCUR AGAIN IN ANOTHER 70-80,000 MILES, SHOULD I OWN THE VEHICLE FOR THAT LONG. THERE ARE SEVERAL PETITIONS ON THE INTERNET REGARDING THIS FAULTY EQUIPMENT, ADVOCATING FOR A GM RECALL. GM, HOWEVER, HAS DONE NOTHING TO RECTIFY THIS PROBLEM. GM SHOULD BE RESPONSIBLE FOR THE COST INCURRED FOR THE REPLACEMENT ON THE LOWER INTAKE MANIFOLD GASKET ON AFFECTED GM VEHICLES, AS THEY CLAIM THE SYSTEM IS GOOD FOR 150,000 MILES WITH THE DEX COOL COOLANT, WHICH IS CLEARLY A FALSE CLAIM. *JB
FAILURE OF COOLING SYSTEM, ENGINE INTAKE MANIFOLD GASKET. VEHICLE IS 1999 BUICK CENTURY WITH ONLY 41000 ORIGINAL MILES. ENGINE OIL LEAKED INTO COOLING RADIATOR. *NM
INTAKE GASKET FAILED ON 3.1 ENGINE IN A 1999 BUICK CENTURY. THIS ENGINE HAS LESS THAN 55,000 MILES ON IT AT THE TIME OF FAILURE. IT APPEARS AS IF THERE ARE MANY OTHER COMPLAINTS FOR THE SAME ISSUE AND THE MANUFACTURER DENIES THAT THERE WAS FAULTY WORKMANSHIP INVOLVED. ESTIMATED COST OF REPAIR $700.00 ALSO SAME CAR WITH LESS THAN 20,000 MILES THE BOLT HOLDING THE LEFT FRONT CALIPER FELL OFF WHILE TRAVELING DOWN THE ROAD WITH MY DAUGHTER DRIVING (DRIVERS PERMIT) AND LOCKED UP THE LEFT FRONT WHEEL DAMAGING THE RIM. COST OF REPAIR $350.00. *JB
DT: THE CONSUMER OWNS A 1999 BUICK CENTURY. HE STATES THAT SIX MONTHS AFTER HE PURCHASED THE VEHICLE HE TOOK THE VEHICLE IN FOR A RECALL ON THE HEADLIGHTS. WHILE THE VEHICLE WAS THERE THEY MAINTENANCE THE VEHICLE AND FOUND THAT THE GAS FILLER PIPE HAD DETERIORATED AND THE COOLING SYSTEM INTAKE WAS LEAKING COOLANT. THIS VEHICLE ONLY HAS ABOUT 50,000 MILES. BOTH FRONT LOWER CONTROL ARM BUSHINGS HAD BLOWN OUT AND THEY HAD TO BE REPLACED ALSO. WYOMING VALLEY MOTORS PO BOX 1308 KINGSTON, PA 18704-0308. HE HAS SPOKEN WITH GM THEY TOLD HIM THEY WOULD GET BACK WITH HIM IN A COUPLE OF DAYS AND THEY DID NOT CONTACT HIM BACK. HE IS NOT AVAILABLE UNTIL AFTER 4:30. THEY TOLD HIM THE GAS FILLER PIPE WAS NORMAL FOR THE VEHICLE. HE SEEN A ARTICLE THAT SAID THEY HAD BEEN HAVING THIS PROBLEM WITH YEAR FOR THE COOLING SYSTEM. THEY ALSO SAID THE BUSHINGS WAS NORMAL WEAR ON A CAR ALSO. HE DID GO ONTO CARFAX AND IT DID NOT INDICATE ANY TIME OF PROBLEMS WITH THE VEHICLE. *JB *NM
THE INTAKE MANIFOLD WAS LEAKING ANTIFREEZE, WHICH COULD CAUSE THE VEHICLE TO OVERHEAT. MANUFACTURER WAS CONTACTED BY CONSUMER.*AK THE ENGINE LOCKED UP DUE TO LOSS OF COOLANT. THE WATER PUMP STARTED LEAKING AT THE SHAFT SEAL WITH LESS THAN 43000 MILES ON THE VEHICLE. A DIRTY, OILY SUBSTANCE WAS NOTICED IN THE RADIATOR NECK. *TC
COOLANT IN OIL - HEAD GASKET FAILURE -*AK
CAR STARTED TO LEAK ANTI-FREEZE VERY SLOWLY. HAS THE DEXCOOL ANTIFREEZE. I CHECKED THE RADIATOR TO SEE IF IT WAS LOW, AND THE RADIATOR LOOKED AS THOUGH IT HAD LOTS OF RUST IN IT. SO I TOOK IT TO A LOCAL FIRESTONE STORE TO HAVE IT LOOKED AT, AND THEY FOUND THE LEAK AND PROCEEDED TO TELL ME THAT THIS WAS A COMMON OCCURRENCE IN GM VEHICLES AROUND THIS MODEL YEAR WITH THE 3.1 LITER ENGINE, THAT A MANIFOLD GASKET WOULD START TO LEAK, AND YOU EITHER GOT ANTIFREEZE LEAKING INTO THE OIL, OR AS IN MY CASE, THE OIL FROM THE ENGINE GOT INTO THE COOLING SYSTEM, HENCE INTO THE RADIATOR AND TURNED IT INTO "GUNK". THE PRICE TAG TO DO THE WORK WAS AROUND $700. SO I THOUGHT I WOULD CALL THE BUICK DEALER IN TOWN TO SEE WHAT THEY KNEW ABOUT THIS PROBLEM AND SEE WHAT THEY WOULD CHARGE TO FIX IT. I FOUND IT IRONIC THAT THE GENTLEMAN IN THE SERVICE DEPARTMENT KNEW EXACTLY WHAT I WAS TALKING ABOUT, SAID THEY THE PARTS ON HAND TO FIX IT AND QUOTED ME THE EXACT PRICE WITHOUT EVEN TAKING A BREATH. SEEMS THIS IS A RATHER COMMON OCCURRENCE WITH THESE ENGINES. WHICH LEADS ME TO BELIEVE THAT THIS IS SOME SORT OF MANUFACTURING DEFECT, AND THAT PERHAPS GM/THE MANUFACTURER SHOULD BE PICKING UP THE BILL FOR THIS FIX. THE SERVICE MAN AT THE FIRESTONE STORE SAID THE SAME THING, THAT THIS IS GETTING TO BE PRETTY COMMON WITH THESE CARS AND COULD RECITE THE NECESSARY WORK THAT NEEDED TO BE DONE TO FIX IT RIGHT OFF THE TOP OF HIS HEAD. SO I WOULD LIKE TO REGISTER MY COMPLAINT IN HOPES THAT SOMETHING COULD BE DONE TO RECTIFY THE SITUATION. THE CAR IS IN THE SHOP PRESENTLY BEING REPAIRED. THE HEAD GASKET AND MANIFOLD GASKETS NEED TO BE REPLACED, WHICH CONSTITUTES TEARING HALF THE ENGINE APART. ALSO THE OIL NEEDS TO BE CHANGED A COUPLE OF TIMES TO GET ANY COOLANT OUT OF THE ENGINE, AND OF COURSE THE RADIATOR NEEDS TO BE FLUSHED, CLEANED AND REFILLED. NO OLD PARTS WOULD BE AVAILABLE AS WHAT NEEDS TO BE REPLACED ARE GASKETS.*AK
1999 BUICK CENTURY DEVELOPED A ROUGH IDLE RIGHT AFTER START UP. THEN CHECK ENGINE LIGHT COMES ON. *BF NAR *JLS THE PROBLEM RESTRICTED THE FUEL INJECTORS. THE SERVICE ENGINE SOON LIGHT WOULD FLASH AND AFTER SOME DRIVING, IT WOULD RESET ITSELF AND RUN OKAY UNTIL THE NEXT COLD START CYCLE REPEATS ITSELF. *SC
DRIVING DOWN ROAD ONE DAY WHEN CAR OVERHEATED. ONE MECHANIC REPLACED THERMOSTAT BUT CONTINUED TO DO SAME. TOOK TO ANOTHER FACILITY WHO RAN DIAGNOSTIC TEST AND WAS TOLD THAT IT WAS THE R & R INTAKE MANIFOLD GASKET. CAR IS A 1999 BUICK CENTURY WITH ONLY 46,191 MILES. HAVE BEEN TOLD THE COST TO FIX PROBLEM IS APPROX. $700. WITH ALL OF THE OTHER IDENTICAL PROBLEMS OF OTHER OWNERS WHY HASN'T SOMETHING BEEN DONE WITH THIS PROBLEM? CONSUMER SHOULD NOT HAVE TO FOOT THE BILL FOR GM'S DEFECTIVE PARTS. THERE IS OBVIOUSLY SOMETHING WRONG WITH THE ENGINE DESIGN. HAD A BUICK REGAL BEFORE THIS AND IT IS STILL RUNNING WITH OVER 195,000 MILES. NO ENGINE COOLING SYSTEM PROBLEM WITH IT. *JB
WHILE DRIVING AT LOW SPEEDS A SQUEAKING NOISE WAS PRODUCED. *AK
I HAVE A 1999 BUICK CENTURY , I TOOK THE VEHICLE TO HAVE A RADIATOR FLUSH AND WAS ADVISED THAT I COULDN'T HAVE THIS JOB PERFORMED DUE TO A LEAK OR CRACK IN THE INTAKE GASKET. AT THIS TIME I WAS VERY SURPRISE TO SEE THE COMPLAINTS AND THERE IS NO RECALL. THIS IS OUTRAGEOUS THAT NO ONE SEEMS TO CARE THIS IS A VERY EXPENSIVE REPAIR AND SHOULD NOT BE THE RESPONSIBILITY OF THE CONSUMER TO REPLACE. THIS SHOULD'VE BEEN DONE BY GENERAL MOTORS. *NM
