NHTSA Complaint #11268189 — 2011 BUICK ENCLAVE

MY REGULARLY SERVICED 2011 BUICK ENCLAVE WITH APPROXIMATELY 75,000 MILES ON IT BEGAN OVERHEATING LAST SUMMER TO THE POINT WHEN TURNING OFF THE ENGINE THE RADIATOR FAN KEPT RUNNING. MY SERVICING BUSINESS WAS CONTINUALLY ADDING THE RECOMMENDED RADIATOR COOLANT IN AMOUNTS THAT TOTALED 3.7 GAL. BETWEEN MID JUNE, '18 TO SEPT '19. I WAS TOLD BY THE DEALER THE RADIATOR HOLDS 14.2 QTS OF COOLANT WHICH IS 3.5 GAL. SO IT LOST OVER ITS TOTAL CAPACITY. IT DID THE SAME OVERHEATING WITH THE RADIATOR FAN RUNNING AFTER THE VEHICLE WAS TURNED OFF THIS PAST SUMMER. THERE IS A RECALL 13091 ON THIS ISSUE OF A LEAKY WATER PUMP FOR 2008-2010 BUICK ENCLAVES AS WELL AS SIMILAR YEARS FOR TRAVERSES, ACADIAS, AND OUTLOOK ON HFV6 ENGINES (LY7,LLT) I WAS TOLD THAT GM DID NOT CHANGE THE FAULTY WATER PUMP UNTIL 2013 ON THE BUICK ENCLAVES. THE CAR SHOWED NO ERROR MESSAGE OF OVERHEATING OR LOW COOLANT ON THE DISPLAY PANEL. THIS IS A SAFETY ISSUE. IF THE WATER PUMPS GOES OUT WHILE DRIVING IT COULD CAUSE THE ENGINE TO BLOW WITH A POSSIBLE ENGINE FIRE, UNSAFE FOR DRIVER AND PASSENGERS.
