2015 CHEVROLET TAHOE Complaints

FAILURE IN BRAKE VACUUM PUMP CAUSED MY BRAKES TO IMPROPERLY WORK THIS ME REAR ENDING ANOTHER CAR. BRAKE FELT LIKE A ROCK AND PUSHED BACK AGAINST MY FOOT. I WAS IN MOTION AT ROUGHLY 15MPH AND WAS ABLE TO SLOW TO ROUGHLY 8MPH AT A DISTANCE OF ROUGHLY 10 YARDS. THIS WAS DURING RUSH HOUR TRAFFIC. PROBLEM HAD BEEN INTERMITTENT AT VERY LOW PARKING LOT SPEEDS.

THE BRAKE PEDAL BECOMES ALMOST IMPOSSIBLE TO DEPRESS AT LOW SPEEDS CAUSING THE VEHICLE TO ROLL WITHOUT THE ABILITY TO STOP. SEEMS LIKE THE BRAKE BOOSTER IS FAILING TO APPLY PRESSURE TO THE BRAKE SYSTEM. HAVE READ SEVERAL COMPLAINTS ON THIS SO I WANTED TO DOCUMENT ONE MORE CASE TO PUSH GM FOR A RECALL. MY FAMILY ALMOST HAD A BAD CRASH THE OTHER DAY DUE TO THIS AND NOW IT HAPPENS ALL THE TIME. ABS IS NOT ACTIVATING TO CAUSE THIS, IT IS MORE A LACK OF BOOST IN THE BRAKE SYSTEM. WE ONLY HAVE 40,000 MILES ON OUR TRUCK.

AS I WAS BACKING DOWN A HILL MY BREAKS WOULD BARELY FUNCTION. I FINALLY WAS ABLE TO GET MY VEHICLE TO STOP AND TAKE IT TO A DEALERSHIP WHERE I WAS TOLD MY VACUUM PUMP NEEDED REPLACED. I UNDERSTAND THIS HAS HAPPENED TO OTHER CONSUMERS SO I WANTED TO MAKE SURE MY ISSUE WAS DOCUMENTED AS WELL.

TAMARA RECALL. VEHICLE FAILED TO STOP WHILE APPLYING BRAKES AT A VERY SLOW SPEED. WHILE PULLING INTO A PARKING SPACE, UNDER 5MPH, A HEAVY AMOUNT OF PRESSURE WAS APPLIED TO BRAKE PADS AND VEHICLE FAILED TO STOP.

2015 TAHOE WAS BEING BACKING UP INTO PARKING SPACE AND LOST ALL CAPABILITY TO BRAKE. VEHICLE WITH 64,500 MILES (OUT OF WARRANTY) AND NO OTHER PREVIOUS MECHANICAL ISSUE. INCIDENT DID NOT RESULT IN AN ACCIDENT OR INJURY BUT VEHICLE WAS TOWED TO CHEVROLET DEALERSHIP AFTER RESEARCHING PROBLEM AND IDENTIFYING OTHER LATE MODEL CHEVROLET TRUCKS OWNERS WITH SIMILAR BRAKING PROBLEMS. OWNER DESCRIBED PROBLEM AND INFORMED DEALER OF CHEVROLET TECHNICAL SERVICE BULLETIN. VEHICLE WAS REPAIRED WITH REPLACEMENT OF BRAKE BOOSTER, VACUUM PUMP, AND BRAKE VACUUM SENSOR. NO RECURRENCE SINCE REPAIR AND VEHICLE NOW OPERATING AS DESIGNED WITH 66,700 MILES.

BRAKES SUDDENLY BECAME EXTREMELY HARD TO APPLY AT LOW SPEEDS. BRAKE PEDAL WAS STIFF AND WOULDN'T ENGAGE. I FIRST NOTICED IT WHILE PULLING IN A PARKING SPACE THEN REVERSING TO STRAIGHTEN THE VEHICLE. THE BRAKES WOULDN'T ENGAGE AND I HAD TO PRESS THE EMERGENCY BRAKE. THIS FIRST OCCURANCE HAPPENED APPROXIMATELY 5:00 PM ON NOVEMBER 11, 2018 IN ORLANDO, FL. AT THIS TIME, I NOTICED THE ISSUE BUT AFTER I TURNED OFF THE VEHICLE AND RESTARTED, IT APPEARED TO BE RESOLVED. I CONTINUED MY EVENING AND DROVE SEVERAL PLACES AND EVENTUALLY DROVE BACK HOME TO TAMPA, FL WITHOUT ANY ISSUES. UPON REACHING MY DESTINATION AND ATTEMPTING TO PARALLEL PARK, THE BRAKES FAILED AGAIN. I TURNED OF THE CAR AND RESTARTED IT AND THE BRAKES DID NOT ENGAGE AND THE BRAKE PEDAL WAS STIFF. I DID NOT DRIVE IT AGAIN. I SUSPECTED AN ISSUE WITH THE VACUUM PUMP AND HAD THE VEHICLE TOWED TO DIMMITT CHEVROLET IN CLEARWATER, FL THE FOLLOWING MORNING. DIMMITT "VERIFIED CONCERN. PERFORMED DIAG. FOUND ENGINE VACUUM PUMP IS WEAK AND NOT PULLING ENOUGH VACUUM AT TIMES." DIMMITT "REMOVED AND REPLACED VACUUM PUMP."

I JUST HAD THE BRAKE VACUUM PUMP REPLACED ( $750.00 ) NOW I SEE THERE MIGHT BE A RECALL FOR THIS PROBLEM . BRAKES WERE HARD TO PUSH DOWN AT TIMES .

TL* THE CONTACT OWNS A 2015 CHEVROLET TAHOE. WHILE DRIVING APPROXIMATELY 35 MPH, THE BRAKE PEDAL SEIZED WITHOUT WARNING. THE VEHICLE WAS PULLED OVER TO THE SIDE OF THE ROAD. THE CONTACT DEPRESSED THE BRAKE PEDAL A COUPLE OF TIMES AND THE BRAKE POWER WAS RESTORED. THE VEHICLE WAS DRIVEN TO BILL CRAMER CHEVROLET BUICK GMC (850-250-1403, LOCATED AT 2251 W 23RD ST, PANAMA CITY, FL 32405) WHERE IT WAS STATED THAT THERE WAS NO RECALL. THE DEALER REPLACED THE BRAKE VACUUM PUMP. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND DID NOT ASSIST. THE VEHICLE WAS REPAIRED. THE VIN WAS NOT PROVIDED. THE FAILURE MILEAGE WAS APPROXIMATELY 68,000.

VEHICLE BRAKES BECOME HARD TO PRESS WHEN VEHICLE IS IN REVERSE AND SOMETIMES WHEN MOVING SLOWLY IN PARKING LOTS. THIS HAPPENED MULTIPLE TIMES AND MOST RECENTLY AS OF NOVEMBER 25, 2018

MY 4 WHEEL DRIVE TRANSFER CASE MAKES A HIGH PITCHED NOISE WHEN IT IS IN 4AUTO AND 4 HIGH. GM TOLD ME THIS IS A CHARACTERISTIC OF THE TRANFER CASE THATS INSTALLED IN MY SUV. NOT ALL TRANSFERENCE MAKE THIS NOISE, THE TAHOE LOANER CAR DOES NOT MAKE THIS NOISE. MY BOTHERS 2015 SILVERADO MADE THE SAME NOISE IN 4 AUTO AND HIGH
