2015 CHEVROLET SUBURBAN Complaints

WHILE DRIVING THE VEHICLE AT HIGHWAY SPEEDS NORTHBOUND ON THE FL TURNPIKE, THE BRAKE PEDAL BECAME VERY RIGID AND WOULD NOT ALLOW ME TO PRESS THE BRAKE PEDAL DOWN AS USUAL. FURTHERMORE, I HAD TO APPLY A TREMENDOUS AMOUNT OF PRESSURE ON THE BRAKE PEDAL TO ENGAGE ANY SORT OF BRAKING WHATSOEVER. IN A SPLIT SECOND, I HAD TO PULL TO THE SHOULDER OF THE HIGHWAY AND CONTINUE APPLYING VERY HARD PRESSURE ON THE BRAKE PEDAL UNTIL THE VEHICLE FINALLY CAME TO A FULL STOP. I TURNED THE VEHICLE OFF, STARTED IT AGAIN, TRIED COASTING AND STOPPING THE VEHICLE AND THE BRAKE PEDAL CONTINUED TO BE VERY DIFFICULT TO PRESS AND WOULD NOT ENGAGE AND PROVIDE NORMAL BRAKING PRESSURE. I THEN HAD THE VEHICLE TOWED TO THE NEAREST CHEVROLET DEALERSHIP AND THEY DIAGNOSED THE ISSUE AS BEING A BAD PUMP IMPACTING THE MASTER BRAKE CYLINDER. PARTS ARE SUPPOSEDLY ON BACK ORDER WITH NO TIMEFRAME GIVEN AS TO THE REPAIR.

DRIVING AT LOW SPEEDS THE BRAKING SYSTEMS FAILS TO STOP THE VEHICLE. THIS ALMOST CAUSED US TO STRIKE A PARKED VEHICLE IN A PARKING LOT. THE DEALERSHIP STATED THE BRAKE VACUUM PUMP HAS A LEAK AND/OR IS FAULTY.

TL* THE CONTACT OWNS A 2015 CHEVROLET SUBURBAN. WHILE ATTEMPTING TO REVERSE OUT OF A PARKING SPACE, THE BRAKE PEDAL BECAME STIFF WHEN DEPRESSED AND THE VEHICLE WOULD NOT STOP. THE CONTACT STATED THAT THE FAILURE OCCURRED SPORADICALLY FOR THREE WEEKS. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 65,000.

WATER IS LEAKING INTO ROOF MOUNTED ANTENNA AND IS PREVENTING ONSTAR SYSTEM TO DETERMINE LOCATION OF VEHICLE BY DISABLING COMPASS, XM RADIO SYSTEM, NAVIGATION. A RED X APPEARS UNDER THE GPS SYMBOL IN THE DISPLAY UNIT WHEN THE VEHICLE IS ON, MOVING, AND STATIONARY. IF YOU LIFT ON THE SHARKFIN ROOF ANTENNA OVER THE DRIVER'S SEAT WATER RUNS OUT. THIS IS IDENTICAL TO THE PROBLEMS IN NHTSA ID NUMBER: 10058785; HOWEVER GM TELLS ME THAT MY VEHICLE VIN IS NOT COVERED UNDER THAT ISSUE ID.

WHILE ON A CITY STREET IN STOP AND GO TRAFFIC THE BRAKE PEDAL BECAME EXTREMELY HARD TO PUSH AND BECAUSE OF THIS IT WAS VERY DIFFICULT TO STOP THE VEHICLE.

IN LATE DECEMBER 2018, THE BRAKES BEGAN TO EXHIBIT SIGNS THAT THEY NEEDED TO BE REPLACED. BEFORE WE COULD GET THE CAR TO THE DEALERSHIP FOR A BRAKE INSPECTION IN EARLY JANUARY 2019 DUE TO THE HOLIDAYS, THE BRAKES ACTUALLY TOTALLY FAILED TO OPERATE AT SLOWER SPEEDS (BELOW 30 MPH). EVEN WHEN "STANDING ON THE BRAKE PEDAL" WITH BOTH FEET THE VEHICLE WOULD NOT STOP. THIS HAPPENED SEVERAL TIMES ESPECIALLY AT SLOW SPEEDS WHILE BACKING OUT OF A DRIVEWAY OR GOING THROUGH A DRIVE-THRU. THE "BRAKE ASSIST LIGHT" ALSO CAME ON DURING SEVERAL OF THESE EVENTS. ALSO, A "GRINDING" NOISE OCCURRED. THIS MAY HAVE BEEN THE ANTI-LOCK BRAKE SYSTEM ACTIVATING. THE VEHICLE IS NOW AT THE CHEVROLET DEALERSHIP IN OUR AREA WAITING ON REPAIRS THAT WE ARE CONCERNED WILL NOT CORRECT THE PROBLEM AND PREVENT IT FROM OCCURRING AGAIN. THIS CONCERN IS DUE TO THE FACT, THROUGH OUR RESEARCH, THAT THERE ARE PENDING LAWSUITS AGAINST GM AND GM ITSELF HAS ISSUED SEVERAL "SERVICE BULLETINS" ADDRESSING THIS ISSUE, BUT WILL NOT INITIATE A RECALL OF THE AFFECTED VEHICLES. THEY WON'T EVEN OFFER ANY REASONABLE SOLUTION TO TRULY PREVENT FUTURE BRAKE FAILURE EVEN AFTER THEIR RECOMMENDED REPAIRS ARE COMPLETED AND PAID FOR.

HI THERE ; BRAKE VACCUM PUMP DEFECTED ; ONCE GOING IN SLOW TRAFFIC , STOP AN GO , OR EVEN BACKING , BRAKE PEDAL GOES HARD AND LOW , SUV DO NOT STOP AND YOU HAVE TO REALLY PRESS BRAKE ! AND THAN STILL GOING , VERY DANGREOUS ! THERE SHOULD BE A SAFTEY RECALL ON ALL 2015 , 2016 , 2017 SUBURBANS . IT COULD BE IN CITY STREETS , MY DRIVE WAY , ANY SLOW DRIVE BACK OR FORTH

WHILE PARKING THE VEHICLE AT A SLOW SPEED THE BRAKES BECAME EXTREMELY HARD TO PUSH AND THE VEHICLE BARELY CAME TO A STOP. THIS HAS HAPPENED MULTIPLE TIMES IN THE PAST FEW MONTHS. WHEN WE HAD IT CHECKED BY THE DEALERSHIP THEY SAID THEY COULDN'T FIND ANYTHING WRONG.

POWER STEERING FAILED DURING TURN AROUND ON A COUNTY ROAD, CAUSING MY VEHICLE TO GO INTO A DITCH, WHICH DAMAGED THE FRONT END OF VEHICLE. THE RECALL UPDATE DID NOT FIX THE VEHICLE ISSUE.

INTERMITTENT HARD BRAKE PEDAL AND NO BRAKES DRIVING SLOW SPEEDS IN STOP-AND-GO TRAFFIC ON I70 DRIVING DOWNHILL OUT OF THE MOUNTAINS TOWARD DENVER, CO.
