“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.”
“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.”
