WHILE DRIVING MY YUKON, I WAS PREPARING TO STOP A LIGHT ONLY TO STRUGGLE WITH PRESSING THE BRAKE PEDAL, ALMOST HIT A VEHICLE THAT WAS IN FRONT OF ME

BRAKES GET HARD WHEN TOWING MY BOAT AND SOMETIMES IN STOP AND GO TRAFFIC.

NHTSA ODI 11196732

BRAKE PEDAL GETS HARD IN SLOW MOVING AND STOP & GO DRIVING CAUSING VEHICLE TO BE HARD TO STOP WITH NO BREAK POWER. THIS SITUATION GETS WORSE WHEN TOWING A TRAILER IN TRAFFIC AN DOWN HILL WHERE YOU NEED THE BRAKE POWER

MY GMC YOUKON DENALI HAS BRAKE LIGHTS THAT ARE KNOWN TO DEALERS TO FAIL. YET THERE IS NOT A RECALL. I LOOKED ON THE INTER NET AND SAW THAT THERE HAS BEEN THIS PROBLEM SINCE 2015 TO 2018. BECAUSE OF A JOINT THAT WAS SOLDERED INSTEAD OF A WIRE. I KNOW WHY WHEN I BROUGHT IT IN FOR RECALL THAT THE SERVICE MAN LOOKED AT MY STOP LIGHTS.

NHTSA ODI 11195738

BRAKES ARE UNRESPONSIVE AND STUFF BRAKE PEDALS AT LOW SPEEDS. WHILE DRIVING AT VERY LOW SPEEDS THE BRAKES WILL NOT ENGAGE AND STOP THE VEHICLE. I WAS PULLING INTO A PARKING STOP AND THE BRAKES WOULD NOT RESPOND UNLESS I STOMPED ON THEM GOING LESS THAN 5MPH. IT HAPPENS OFTEN WITH THE SAME SCENARIO. DRIVING AT A VERY LOW RATE OF SPEED AND MY VEHICLE WILL NOT STOP WHEN THE BRAKES ARE PRESSED.

WITHIN THE LAST YEAR ON MY 2015 MY AC COMPRESSOR HAS GONE OUT, RADIO SCREEN QUIT WORKING, BRAKE PUMP/BOOSTER FAULTY, AND NOW REAR BRAKE LIGHT QUIT WORKING. ALL SEEM TO BE VERY COMMON IN THIS YEAR MODEL. MY CAR HAS LESS THAN 70000 MILES ON IT!! GM IS EITHER DOING A CRAPPY JOB ON THEIR $60000 VEHICLES OR A RECALL NEEDS TO BE DONE.

INTERMITTENT BRAKE LIGHT ACTIVATION ON BOTH LEFT AND RIGHT. IT HAPPENS STOPPED AND IN MOTION. VERY DANGEROUS! IT IS A KNOWN ISSUE WITH BROKEN CONTACTS INSIDE A SEALED HOUSING. THE ISSUE IS POSTED ALL OVER THE FORUMS BUT GMC REFUSES RESPONSIBILIY.

POWER BREAKING FAILS WHEN DRIVING AT LOW SPEEDS, BRAKE PEDAL STIFF AND HARD TO PUSH DOWN TO STOP VEHICLE IN BOTH FORWARD AND REVERSE DIRECTIONS WHEN INCHING FORWARD AT A STOP LIGHT/SIGN, OR PARKING IN A PARKING LOT IN FORWARD AND REVERSE CAR KEEPS MOVING. STOPPING REQUIRED VERY HARD PUSH ON THE STIFF BRAKE PEDAL.. BRAKING AT HIGHER SPEEDS LESS AFFECTED BUT SUDDEN STOPS CAN REQUIRE MORE FORCE THAN USUAL AS THE CAR SLOWS DOWN. PROBLEM BEGAN DECEMBER 2017 RARELY AND INTERMITTENTLY, AND INCREASED TO ALL THE TIME BY FEBRUARY 2019 AT LOW SPEEDS THE POWER BRAKE DID NOT WORK AND REQUIRED MUCH FORCE ON THE BRAKE PEDAL TO STOP VEHICLE EVERY TIME. BRAKE FLUID WAS FINE AND SO WAS BRAKE PADS. GM DEALERSHIP VISIT SHOWED A FAILURE OF THE VACUUM PUMP FOR BRAKE LINE AND THEY INSTALLED A REDESIGNED PUMP WHICH SHOWS THAT THE ORIGINAL HAS FAULTY DESIGN. THEY ALSO REQUIRED A BELT THAT OPERATES PUMP TO BE REPLACED AS WELL. THIS SEEMS TO HAVE FIXED THE PROBLEM FOR NOW BUT THIS REPAIR HAS A TWO YEAR GUARANTEE. PRICE FOR ME TO FIX OVER $881+TAX.

I LOST BRAKES. EXTREME PRESSURE ON PEDDLE REQUIRED FOR BRAKES TO ENGAGE. EVEN THEN ONLY REDUCED BRAKING POWER WAS AVAILABLE. REQUIRED REPLACEMENT OF VACUUM PUMP AND BOOSTER. OCCURRED WHEN VEHICLE ENGINE WAS AT IDLE. OTHERWISE BRAKES FELT WEEK BUT AVAILABLE.

BRAKE PEDAL IS STIFF AT LOW SPEEDS. THE PEDAL LOCKS UP AND STOPPING IS DELAYED 2 TO 3 FEET. IT MAKES OPERATING THE VEHICLE UNSAFE. I HAVE DONE RESEARCH ON THIS ISSUE. OTHERS ARE EXPERIENCING THE SAME DANGEROUS DELAYED STOPPING DISTANCE AND STIFF BRAKE PEDAL AT LOW SPEEDS.

BRAKING BECOMES "HARD" AFTER BRAKING WHILE MOVING (E.G. IN RUSH HOUR TRAFFIC OR SLOWLY GOING DOWN A HILL).THIS STARTED WHILE GOING DOWNHILL IN AN ANIMAL RESERVE. I WAS INCHING FORWARD TO GET BETTER VIEWS OF THE ANIMALS. HALFWAY DOWN THE HILL THE BRAKES COMPLETELY FAILED. I HAD TO LITERALLY STAND UP ON THE BRAKE, AND IT STILL WOULDN'T STOP THE CAR. AFTER TAKING MY FOOT OFF THE BRAKE FOR A BIT, THE PROBLEM FIXED ITSELF. WHEN I TOOK IT TO THE DEALER, THEY SAID IT WAS A FAULTY VACUUM PUMP ($500 REPAIR), BUT ONLINE RESEARCH SAYS REPLACING THE VACUUM PUMP DOESN'T SOLVE THE PROBLEM. NOTE, THIS PROBLEM CONTINUES TO PERSIST.

FROM TIME TO TIME BRAKE PEDAL BECOMES HARD WHEN BACKING UP OR GOING FORWARD MAKING THE VEHICLE HARD TO COME INTO A COMPLETE STOP.

'TAKATA RECALL' WE JUST PURCHASED OUR 2015 YUKON DINALI XL DECEMBER 20, 2018 AND HAVE HAD NOTHING BUT PROBLEMS WITH BRAKE LIGHT ( WHILE IN MOTION ) ON DRIVER-SIDE WORKING INTERMITTENTLY, SO WE REPLACED BOTH TAILLIGHTS WITH BRAND NEW ($700) ENCLOSED REAR LIGHT ASSEMBLY AND NOW WE ARE HAVING AN ISSUE WITH DRIVER SIDE ONCE AGAIN. I'M VERY PROUD TO BUY AMERICAN MADE PRODUCTS BUT AFTER SEEING HOW MANY GMC MONTHLY COMPLAINTS WITH THIS SAME ISSUE, YOU WOULD THINK THAT GM WOULD STAND BEHIND THEIR PRODUCT. I KNOW MYSELF BEING IN BUSINESS IF I HAD A COMPLAINS MORE THAN THREE TIMES A MONTH I WOULD TRY MY BEST TO CORRECT THE PROBLEM TO KEEP FROM HAVING A BAD REPUTATION AND HAVE A FUTURE CUSTOMERS!! I TAKE PRIDE IN MY WORK FOR WHAT OUR CUSTOMER PAYS, AND EXPECT THE SAME FOR WHAT I PAY!!

WHEN SLOWLY TURNING INTO GARAGE, BRAKE PEDAL BECAME "HARD" AND REQUIRED SIGNIFICANT FOOT FORCE TO STOP THE VEHICLE. THE CONDITION HAS NOT IMPROVED AND I WILL HAVE TO TOW THE VEHICLE TO THE DEALERSHIP FOR REPAIRS.

FAULTY BRAKE VACUUM PUMP CAUSED VEHICLE TO NOT BRAKE AT SLOW SPEEDS WHEN ATTEMPTING TO STOP IN DRIVE THRU RESTAURANT AND STOP LIGHT ON STATE ROUTE.

VEHICLE TAIL LIGHTS AND BRAKE LIGHTS QUIT WORKING. THE LED CIRCUITS BREAK CAUSING THE CONNECTION TO SHORT OUT. BOTH THE TAIL LIGHTS AND BRAKE LIGHTS DO NOT WORK ONCE THE CIRCUIT IS BROKE. THE OWNER CAN'T SIMPLY FIX THE BURNT OUT TAIL LIGHT. ONE MUST COMPLETELY REPLACE THE ENTIRE ASSEMBLY, COSTING UPWARDS OF $1,000 FOR BOTH. THIS IS NOT COST EFFECTIVE AND IS DOWNRIGHT HAZARDOUS WHEN BOTH TAIL LIGHTS GO OUT, FOR BOTH THE OWNER AND OTHER DRIVERS ON THE ROAD. THE TAIL LIGHT ASSEMBLY SHOULD BE ABLE TO RESIST ROAD BUMPS AND VIBRATIONS.

REAR LED BRAKE LIGHTS ONLY WORK INTERMITTENTLY.

THE BRAKE LIGHTS ON MY 2015 GMC YUKON XL HAVE BOTH GONE OUT. I HAVE BEEN PULLED OVER AND QUESTIONED ABOUT IT SEVERAL TIMES BY MY LOCAL LAW ENFORCEMENT. I BELIEVE THE MANUFACTURER STATE THAT THEY HAVE A LIFE OF 40,000 HOURS OF CONTINUOUS USE BUT, ONLY FUNCTION FOR A FRACTION OF THIS AMOUNT & THEY ARE $600-700 TO REPLACE.

WHEN TOWING A SMALL CAMPER AND TRAVELING AT SLOW SPEEDS MY BRAKE BECOMES HARD AND MUST BE PRESSED VERY HARD TO SLOWLY STOP THE CAR. THIS DOES NOT HAPPEN ALL THE TIME BUT HAS HAPPENED MULTIPLE TIMES AND IS QUITE SCARY. THE VEHICLE TRAVELS FURTHER BEFORE STOPPING THAN WITH PROPER BRAKING WHICH HAS THE POTENTIAL OF PUTTING ME IN A DANGEROUS SITUATION. DEALER SAYS IT IS A VACUUM PUMP BEGINNING TO FAIL BUT THERE ARE NO PUMPS AVAILABLE NATIONWIDE SO I CANNOT HAVE IT REPAIRED! NOTES ABOUT DATES AND MILEAGE ARE FOR THE LAST OCCURRENCE AND AS CLOSE AS I CAN RECALL FOR EACH.

NHTSA ODI 11165893

ON TWO SEPARATE OCCASIONS WHEN PARKING, AND DRIVING AT A HIGH RATE OF SOEEDV( 60 MPH)ON INTERSTATE IN SUDDEN STOP AND GO TRAFFIC BRAKES FAILED TO ENGAGE AFTER WORKING PROPERLY BEFORE AND AGAIN AFTER WITH MORE THAN A MONTH BETWEEN INCIDENTS . THE SECOND INCIDENT OCCURRED ON 12/31/18 AFTER THE VEHICLE HAD BEEN IN FOR ROUTINE OIL CHANGE AND SERVICE THAT INCLUDED A MULTI POINT INSPECTION AT THE GMC DEALERSHIP WHERE IT WAS PURCHASED BRAND NEW. THE VEHICLE IS FREQUENTLY SERVICED AS REQUIRED AND HAS TIRES WITH GOOD TREAD . THE FAILURE IS ALARMING AS IT OFTEN COMES WHEN TRYING TO MAKE A NECESSARY STOP AND THE FAILURE COMES OUT OF THE BLUE THEN RETURNS TO NORMAL. THIS OCCURRENCE SHOULD BE ADDRESSED BY THE MANUFACTURER AND SHOULD BE TAKEN VERY SERIOUSLY SINCE THE MATTER IS LITERALLY A MATTER OF LIFE AND DEATH. I WILL BE MAKING AN APPOINTMENT FOR MY VEHICLE TO BE CHECKED OUT AND WILL UPDATE THE DEALERSHIP FINDINGS .

POWER BRAKES FAILING AT LOW SPEEDS-IN FREEWAY TRAFFIC-PULLING INTO DRIVEWAY REQUIRES STRONG PRESSING ON BRAKE PEDAL AS IF THE BRAKES ARE INTERMITTENTLY LOOSING POWER ASSIST

AT SLOW SPEED IN STOP AND GO TRAFFIC THE BRAKES WILL WORK ONE TIME AND THE NEXT TIME I WOULD HAVE TO STOMP THE BRAKE PEDAL TO GET THE SUV TO STOP IT WAS ON A STREET WHEN IT HAPPENED I HAVE TRIED TO CONTACT FLOW GMC OF WINSTON-SALEM MULTIPLE TIMES AND CAN'T GET ANYONE TO TALK TO ME

WHEN COMING TO A STOP, THE BRAKE PEDAL BECAME STIFF AND DID NOT ENGAGE. THIS HAS HAPPENED ON MULTIPLE OCCASIONS IN THE PAST, AND HAPPENS WHEN THE VEHICLE IS TRAVELING AT SLOW SPEEDS (LESS THAN 5MPH). THE ISSUE IS A FAULTY POWER BREAK PUMP.
