2012 BUICK ENCLAVE Service Brakes Problems

I purchased this vehicle (used)on 01/12/2021. 5 weeks later the brakes pedal went to the floor. It has done this randomly several times. Usually I can get the car stopped, put it in park and pump the brake pedal a few times and the pedal will be back to normal.When this happens it's usually at a low speed and I can get the car stopped but it takes a while. I have attempted to talk to Gen. Motors at Detroit seeking information as to how can I repair this problem. I got no help from Detroit. My local Buick shop manager tells me it could be any number of things. Maybe a sensor or something in the brake system or a vaccuum problem. I need to know what to do to fix this problem before I get into a wreck.

TL* THE CONTACT OWNED A 2012 BUICK ENCLAVE. WHILE DRIVING APPROXIMATELY 5-10 MPH, THE BRAKE PEDAL WAS DEPRESSED, BUT FAILED TO STOP THE VEHICLE. THE CONTACT ATTEMPTED TO SHIFT THE VEHICLE INTO REVERSE AND PARK; HOWEVER, THE VEHICLE KEPT ROLLING FORWARD AND CRASHED INTO ANOTHER VEHICLE. THERE WERE NO INJURIES AND A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO BALLAS BUICK GMC (LOCATED AT 5715 CENTRAL AVE, TOLEDO, OH 43615, (419) 464-7699) TO BE DIAGNOSED, WHICH WAS STILL PENDING. THE VEHICLE WAS SALVAGED. THE MANUFACTURER WAS NOT INFORMED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 75,000. *TP *PM

WE PURCHASED A 'CERTIFIED PRE-OWNED' 2012 BUICK ENCLAVE FROM ROYAL BUICK OF SUSSEX NEW JERSEY IN FEBRUARY OF 2017. THE CAR SHUT OFF ON FRIDAY JANUARY 11TH. IT WAS TOWED TO ROSSI WHERE WE HAVE BEEN TAKEN IT FOR ALMOST TWO YEARS OF ONGOING MAINTENANCE, BOTH SCHEDULED AND NON, AND HAVE SPENT OVER $10K IN THE LAST YEAR ALONE, ON SERVICE THAT DID NOT RESOLVE THE CLICKING SOUND COMING FROM THE ENGINE. EARLIER THAT DAY I HAD MADE THE EARLIEST APPOINTMENT AVAILABLE WHICH WAS 10 DAYS LATER, ON THE 21ST. AFTER BREAKING DOWN, WE WENT TO THEIR SHOWROOM THAT FOLLOWING SATURDAY AND WERE SEEN BY CHARLIE. HE WROTE UP A VERY REASONABLE DEAL FOR $1K DOWN WITH MANY INCENTIVES INCLUDING ONE FOR ME BEING A VOLUNTEER EMT. MATT THE SALES MANAGER CAME BACK AND TOLD US THAT MY WIFE'S CREDIT SCORE WAS NOT WHAT WE HAD CLAIMED AND QUALIFIED FOR...

I PURCHASED THIS CAR FROM SUNTRUP FORD WESTPORT IN JULY 2018. THE DAY I TOOK IT HOME I FOUND ONE ISSUE WITH THE RACK AND PINION AND IMMEDIATELY TOOK THE VEHICLE TO MY LOCAL MECHANIC TO BE LOOKED OVER. AFTER BEING GIVEN A LIST OF ISSUES I TOOK THE CAR BACK TO THE DEALERSHIP AND WAS TOLD THAT ALL OF THE ISSUES WOULD BE ADDRESSED AND FIXED. 2 MONTHS AND NO COMMUNICATION LATER I GET MY CAR BACK AND THE BRAKE BOOSTER STILL WAS NOT FIXED, MAKING THE CAR UNSAFE FOR MYSELF AND MY TWO CHILDREN TO BE IN. THE DEALERSHIP IS NOW REFUSING TO FIX THE BRAKE BOOSTER WHICH WAS ON THE ORIGINAL LIST OF THINGS WRONG WITH THE CAR AND MAKING IT UNSAFE TO DRIVE. THIS INCIDENT TOOK PLACE BETWEEN JULY 21ST 2018 TILL SEPT 26TH 2018

THE CAR WAS BOUGHT BRAND NEW IN 2013. MY WARRANTY EXPIRED 2 MONTHS AGO. THE CAR HAS ONLY 27K MILES. ALREADY THE POWER STEERING FLUID LINE BROKE AND LEAKING, CAUSING VERY UNSAFE STEERING MANIPULATION. THE BRAKE CALIPERS HAVE FAILED AND LEAKING BRAKE FLUID AGAIN CAUSING UNSAFE DRIVING CONDITIONS. BUICK WILL NOT FIX THESE ISSUES, WHICH CLEARLY ARE A RESULT OF POOR QUALITY.

TWICE IN THE LAST 30 DAYS OUR ENCLAVE WAS SHOWING LOW ON GAS (USUALLY NOT AN ISSUE) BUT BOTH TIMES THE CAR SPUTTERED TO A STOP. ONCE IT QUIT I LOST ALL POWER STEERING AND BRAKING. EVEN AFTER I PUT GAS IN THE CAR, THE KEY WOULD NOT MOVE SO I WAS UNABLE TO START THE CAR WITHOUT A JUMP. CAR WAS TOWED TO DEALERSHIP. THEY WERE UNABLE TO RECREATE THE ISSUE ALTHOUGH THEY WERE UNABLE TO EXPLAIN WHY THE KEY WOULD LOCK UP IN THE IGNITION. ACCORDING TO BUICK EVERYTHING CHECKED OUT FINE. BASED ON WHAT WE ARE HEARING ON THE NEWS, THIS ISSUE SEEMS VERY SIMILAR TO THE COBALT ISSUE. THANK YOU. *TR
