Engine and engine cooling

28 reports
“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.”

Power train

22 reports
“WE PURCHASED THIS CAR (AS IS) FOR OUR GRANDSON. ON OUR WAY HOME FROM THE DEALER, AS SOON AS THE TRANSMISSION WARMED UP (4-5 MILES), THE SHIFTING WAS HARD AND JERKING WITH A WHINE COMING FROM THE TRANSMISSION. TOOK THE CAR TO A GARAGE WHICH FOUND THE COMPUTER CODE OF P1811 AND WERE TOLD A COMPLETE REBUILD WOULD BE NECESSARY. WENT ONLINE AND DISCOVERED MANY OTHERS HAD COMPLAINTS OF THE SAME NATURE. WOULD HOPE GM WOULD COME FORWARD WITH REIMBURSEMENT SINCE ITS TRANSMISSION IN THIS MODEL WAS INCORRECTLY DESIGNED. THE REBUILDING GARAGE OWNER EVEN HAD TO GO TO A SPECIAL SCHOOL TO LEARN HOW TO CORRECT THIS PROBLEM IN THE BUICK CENTURY. AFTER PAYING $1,757.25 TO QUEENS TRANSMISSION, INC., IN BRADENTON, FL (941-746-7480), THE SHIFTING IS NOW NORMAL.”

Vehicle speed control

19 reports
“When I have cruise control on but not in use at that moment the car will engage cruise on its own. It does this at a high rate of acceleration with no Rhyme or Reason as to why. I have to be quick to get it to stop because of the high rate of speed. I do not use the cruise control anymore on my vehicle because of being unsafe. I have been lucky a couple of times I have not rammed into the vehicle in front of me through no fault of mine except for having cruise control on. No it has not been examined or inspected. The problem has not been confirmed by the dealership or and independent service center. It has been confirmed by various drivers of my car. None of them will use cruise control anymore.”

“THE DRIVERS WINDOW WILL GO DOWN WHEN YOU PUT KEY IN IGNITION RIGHT BEFORE YOU START VEHICLE. AFTER IT GOES DOWN YOU MUST WAIT 10 SECONDS OR SO AND YOU CAN PUT WINDOW UP. THIS IS THE EXACT SAME ISSUE MY 2007 CHEVY TRAILBLAZER IS BEING RECALLED FOR. BUT THE BUICK CENTURY IS NOT ON THE RECALL LIST. *TR”
