What 977 owners told NHTSA about the 2015 GMC Yukon Denali Xl 1500

MY RIGHT REAR TAILLIGHT STOPPED WORKING, INCLUDING THE BRAKE LIGHT. I TOOK IT TO THE DEALERSHIP AND WAS TOLD IT IS A BURNED OUT TAILLIGHT AND HAS TO BE REPLACED. THE COST WAS $800. I WAS UNDER THE IMPRESSION THAT THESE TAILLIGHTS ARE LED AND LAST FOREVER. IN READING ONLINE, IT LOOKS LIKE THIS IS AN ONGOING PROBLEM WITH THESE GMC/CHEVY TAILLIGHTS WHERE THE CIRCUIT BOARD BREAKS AND THE LIGHT STOPS WORKING.

BRAKE LIGHTS WORKING INCONSISTENTLY,

NHTSA ODI 11162896

THE VEHICLE'S TAIL LIGHT ASSEMBLY ON BOTH THE DRIVERS AND PASSENGER'S SIDES ARE DEFECTIVE. THE SOLDER DOES NOT HOLD AND THE VEHICLE'S BRAKE LIGHTS AND RUNNING LIGHTS FAIL INTERMITTENTLY. THE DRIVER IS TOTALLY UNAWARE OF THIS MAJOR ISSUE THAT THE BRAKE LIGHTS ARE NOT WORKING. IN RESEARCHING THIS PROBLEM ON THE INTERNET THERE ARE NUMEROUS CUSTOMERS OF GMC'S YUKON'S AND DENALI'S WHO ARE EXPERIENCING THE SAFETY PROBLEM. I REALIZED THE PROBLEM WHEN ANOTHER MOTORIST ALMOST STRUCK THE BACK OF MY VEHICLE BECAUSE THERE WERE NOT BRAKE LIGHTS AT ALL. THE VEHICLE WAS TRAVELING AND BOTH BRAKE LIGHTS FAILED. THE SIGNAL LIGHTS WILL STILL WORK.

WE WERE STOPPED AT A RED LIGHT TODAY BY SOMEONE TELLING US OUR TAIL LIGHT WAS BLINKING AND GOING OUT. OUR VEHICLE ONLY HAS 65000 MILES! I WOULD THINK A LED LIGHT SHOULD NOT GO OUT YET. MY VEHICLE SITS UNDER A CARPORT WHEN NOT IN USE. I HAVE SEEN NUMEROUS COMPLAINTS ONLINE FOR THIS SAME PROBLEM FOR SAME YEAR MODEL

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

NHTSA ODI 11160672

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

NHTSA ODI 11160740

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.

NHTSA ODI 11157303

TODAY, WHILE 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).

NHTSA ODI 11157178

BRAKE LIGHTS WENT OUT ON BOTH SIDES. ALL OTHER LIGHTS IN UNIT ARE FUNCTIONING FINE. GMC IS REQUIRING ME TO BUY THE ENTIRE LIGHT WHICH IS $750 EACH JUST TO FIX THE BRAKE LIGHT. BOTH LIGHTS WENT OUT AT THE SAME TIME. HAS TO BE AN ISSUE WITH THE LIGHT

NHTSA ODI 11157065

LEFT REAR TAIL LIGHT QUIT WORKING, I WAS ABLE TO BREAK THE COVER OFF AND SOLDERED THE LED MOUNTING STRIP,. RIGHT SIDE QUIT WORKING SO I BROKE THE COVER OFF BUT THIS TIME IT WAS SEVERELY DAMAGED. SOLDERED IT. LEFT SIDE QUIT WORKING AGAIN SO I REPLACED BOTH SIDES WITH AFTERMARKET UNITS. DATE BELOW IS JUST TO FILL THE SPACE. IT WAS AFTER WARRANTY EXPIRED AND OVER ABOUT 6 MONTHS TIME.

NHTSA ODI 11156104

ON MULTIPLE OCCASIONS SPECIFICALLY WHILE TRAVELING AT LOW SPEED RATE SUCH AS SLOW MOVING TRAFFIC OR PULLING IN OR BACKING OUT OF PARKING SPACE. THE BRAKES BECOME HARD TO PUSH AND THE BRAKES DO NOT ENGAGE. YOU MUST PUSH THE BRAKES VERY HARD TO STOP. WE TOOK TO THE GM SERVICE AT OUR DEALERSHIP AND A BRAKE VACUUM PUMP WAS REPLACED. THE NEXT DAY WE WERE DRIVING THE VEHICLE AND THE BRAKES FAILED TO STOP. THANKFULLY WE WERE IN A PARKING LOT AND WERE ABLE TO STOP AGAINST BUMPER STOP. WE CALLED THE GM SERVICE DEALERSHIP AND THEY ARRANGED FOR A TOW. THIS IS EXTREMELY DANGEROUS SITUATION.

NHTSA ODI 11155677

THERE IS A KNOWN ELECTRICAL ISSUE WITH THE YUKON TAIL LIGHTS. THE ENCLOSED LED RUNNING LIGHTS AND BRAKE LIGHTS WILL GO OUT AND NOT OPERATE. THIS IS A HUGE SAFETY CONCERN AS THERE IS NO BRAKE LIGHT THAT WILL ILLUMINATE AND NO RUNNING LIGHT. BOTH OF MY TAIL LIGHTS HAVE GONE OUT ON MY VEHICLE. DURING A RECORD CHECK I HAVE LEARNED THAT THIS IS A COMMON PROBLEM WITH THE YUKON'S. GMC HAS FAILED TO TAKE ACTION ABOUT THE KNOWN PROBLEM. THE PROBLEM IS PERSISTENT WHILE BEING STOPPED AND DRIVING. SECONDLY THE BRAKING VACUUM SYSTEM WILL GO OUT UNEXPECTEDLY. THIS CAUSES THE ASSISTED BRAKES TO FAIL CAUSING THE BRAKING SYSTEM NOT TO TAKE AFFECT AND STOP THE VEHICLE PROPERLY. THIS IS A HUGE SAFETY CONCERN AS YOU WILL NOT BE ABLE TO SAFELY STOP YOUR VEHICLE IN A TIMELY MANNER AND WILL CAUSE SEVERAL ACCIDENTS. I NOTICED THAT THE BRAKES HAD FILLED WHILE BEING STOPPED AT A STOPLIGHT AND ALSO WHILE BEING MOBILE AND DRIVING.

NHTSA ODI 11154888

THE REAR TAILLIGHT WORKS INTERMITTENTLY. I HAVE REPORTED IT TO THE DEALERSHIP AND THE ONLY FIX IS TO REPLACE THE HOUSING UNIT AT $1500. IT HAS BEEN REPORTED AND IS A KNOWN PROBLEM WITH GMC.

TAKATA RECALL. ISSUES WITH BOTH BRAKE LIGHTS GOING OUT.

NHTSA ODI 11154817

WE PURCHASED THIS VEHICLE ON 11.21.18 AND THE BRAKE LIGHTS INTERMITTENTLY DON'T WORK. THEY WERE WORKING AT THE TIME WE DROVE IT OFF THE LOT. THE BULBS WERE TESTED BY OUR MECHANIC AND HE STATED THAT THE GMC YUKON OF THIS YEAR ARE KNOWN TO HAVE MAJOR PROBLEMS WITH THE BRAKE LIGHT HOUSING UNITS ON THE REAR OF THE VEHICLE. THE ELECTRICAL BOARD ASSOCIATED WITH IT HAS ISSUES THE MECHANIC STATED. I REVIEWED MANY POST ONLINE AND WONDER WHY THIS ISN'T A REQUIRED RECALL. TO ME THIS IS A MAJOR SAFETY CONCERN AND WE BOUGHT THIS VEHICLE TO TRANSPORT MY KIDS AND WIFE. I'D LIKE THIS TO BE CONSIDERED A RECALL IMMEDIATELY.

NHTSA ODI 11154415

AT SLOWER SPEED, BRAKES BECOME STIFF AND WAS UNABLE TO STOP VEHICLE. THE BRAKES DID NOT ENGAGE ALL THE WAY TO THE FLOOR AS NORMAL AND INSTEAD STOPPED ABOUT 1/4 OF THE WAY AND WAS SOLID EVEN WHEN PRESSING BOTH FEET ON THE BRAKE. ALMOST REAR-ENDED THE VEHICLE IN FRONT OF ME BUT SINCE I WAS AT SUCH A SLOW RATE OF SPEED I WAS ABLE TO ROLL A FEW FEET AND THE VEHICLE STOPPED. I HAD TO TURN THE VEHICLE COMPLETELY OFF AND START IT BACK UP AND IT SEEMED TO WORK FINE BUT THE NEXT TIME I WAS IN THE VEHICLE AT THE SLOW RATE OF SPEED, THE BRAKES THEN AGAIN WERE VERY HARD TO PRESS. I DO NOT FEEL COMFORTABLE DRIVING THE VEHICLE UNTIL THIS PROBLEM IS TAKEN CARE OF. I CONTACTED THE LOCAL DEALER AND THEY TOLD ME IT WOULD BE 5 DAYS UNTIL THEY COULD GET TO IT - DISAPPOINTED IN THAT CONSIDERING THE SEVERITY OF THE ISSUE.

NHTSA ODI 11154507

TL* THE CONTACT OWNS A 2015 GMC YUKON XL. WHILE DRIVING 5 MPH AND LOW SPEEDS, THE BRAKES SEIZED. WHEN DRIVING AT HIGHER SPEEDS, THE BRAKES PERFORMED PROPERLY. THE CONTACT WOULD HAVE TO PLACE THE VEHICLE IN NEUTRAL AND REV THE ENGINE FOR THE BRAKES TO WORK. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO SEILVEIRA BUICK GMC (985 HEALDSBURG AVE, HEALDSBURG, CA 95448, (866) 572-7256) WHERE IT WAS DIAGNOSED THAT A NEW VACUUM PUMP NEEDED TO BE INSTALLED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND DID NOT ASSIST. THE FAILURE MILEAGE WAS 105,000.

WHILE IN MOTION THE BRAKES WENT OUT COMPLETELY IN JULY 2015. THEN WHILE DRIVING DOWN THE INTERSTATE AT 75 MPH THE BRAKES WENT OUT COMPLETELY IN 2018. BOTH TIMES I WAS CHARGED A DEDUCTIBLE. BOTH TIMES THE COMPLETE BRAKE SYSTEM WAS COMPLETELY REPLACED BY A DEALERSHIP. AFTER THE SECOND INCIDENT I CONTACTED GMC. AFTER NUMEROUS PHONE CALLS THE OFFERED ME $2000 TOWARDS A NEW VEHICLE. I WAS VERY UPSET WITH THEM AND THREATENED TO GET A LAWYER IF I WAS HURT IN THIS VEHICLE OR HURT OTHERS IN THE FUTURE. IT WAS A TERRIFYING EXPERIENCE AND I FELT LIKE I DESERVED MORE. THEY WOULDN'T EVEN PAY FOR THE RENT A CAR I HAD TO USE ON MY VACATION WHILE THE BRAKE SYSTEM WAS REPLACED. I PAID $70,0000 FOR THIS CAR, BUT DON'T WANT TO FEAR LOOSING BRAKES EVER AGAIN!

NHTSA ODI 11153635

WHILE OPERATING THE VEHICLE AND ATTEMPTING A STOP THE BRAKING BECAME POOR AND I HAD TO DEPRESS THE BRAKE PEDAL AS HARD AS I COULD. HOWEVER, EVEN AFTER THAT THE VEHICLE DID NOT STOP RIGHT AWAY AND TOOK MORE DISTANCE TO COME TO A FULL STOP. THE BRAKE FELT "SOFT" AND NOT LIKE IT USUALLY DOES. INTERESTINGLY...THE BRAKE WOULD SEEM TO WORK AGAIN IMMEDIATELY AFTER THE INCIDENT. I'VE HAD PROBABLY 3 OR 4 INCIDENTS, OVER THE PAST YEAR, WHERE THIS HAS HAPPENED. NONE OF THE INCIDENTS HAVE RESULTED IN ANY TRAFFIC INCIDENTS, BUT ALL HAVE REQUIRED MORE STOPPING DISTANCE THAN NORMAL. ALL OF THE INCIDENTS HAVE TYPICALLY OCCURRED AT LOWER SPEEDS (LESS THAN 40 MPH).

NHTSA ODI 11153330

WHEN COMING TO A STOP THERE WOULD BE A SUDDEN SURGE AND IT FELT LIKE THE VEHILCE WAS BEING PUSHED FORWARD. THERE HAS BEEN A FEW OCCASIONS WHERE WE ALMOST HIT SOMETHING IN FRONT OF US BECAUSE OF THIS SURGE. THERE WAS A BAD SHUTTER THOUGH OUT THE VEHICLE AT 30 TO 50 MPH. MADE COMPLAINTS TO DEALER. THEY COULDN'T DUPLICATE THE PROBLEM. THIS WAS AT ROUGHLY 6K MILES AT THE TIME OF THE FIRST OIL CHANGE. AT 10K MILES THE VEHICLE STALLED OUT AND DIED IN OUR DRIVE WAY AFTER PUTTING IT INTO REVERSE TO BACK OUT. THE VEHICLE ROLLED BACK INTO THE STREET AS OUR DRIVEWAY IS AT A INCLINE WITH OUT ANY FUNCTIONS OR CONTROLS. LUCKY TRAFFIC WAS LIGHT AND THEY WERE ABLE TO AVOID HITTING US. I WAS ABLE TO START IT EVENTUALLY AND DROVE ITS STRAIT TO THE DEALERSHIP. THEY FOUND THE TORQUE CONVERTER WENT BAD AND REPLACED IT. COMPLAINED ABOUT THE ROUGH RIDE, NOISES AND LOOSE FEEL COMING FROM THE FRONT END SEVERAL TIMES AT 20,000 MILES AND 30,000 MILES. WHEN DRIVING THE VEHICLE OVER BUMPS WHILE IN A CURVE THE VEHICLE WOULD JERK TO THE SIDE PULLING THE STEERING WHEEL HARD TO THE SIDE IT WAS PULLED TOWARDS. THERE WERE A FEW OCCASIONS WHERE WE ALMOST HIT A VEHICLE OR CONCRETE WALL. THEY FINALLY REPLACE SOME COMPONENTS ON THE FRONT END. NO MORE NOISES FROM THE FRONT END FOR ABOUT 2,000 MILES AND THEN IT COMES BACK. THE SHUTTER IS BACK ALONG WITH ERRATIC SHIFTING. SERVICE REPLACES THE TORQUE CONVERTER AGAIN AT 45,000 MILES. THIS TIME IT LAST A LITTLE BIT LONG AND I DON'T START HAVING ISSUE WITH THE TORQUE CONVERTER UNTIL NEARLY 60,000 MILES. THE FRONT END STILL POPS, CREAKED AND FEELS LOOSE AT TIMES AND THE TORQUE CONVERTOR IS STILL FAILING.

NHTSA ODI 11153413

WHEN MOVING IN A PARKING SPOT THE BRAKE PEDAL BECAME HARD AS IF IT LOST POWER BRAKES, BUT THEN RETURNED. A FEW DAYS LATER ON THE FREEWAY TRAFFIC STOPPED IN FRONT OF US AND IT HAPPENED AGAIN. THIS CAUSED US TO NEED TO SWERVE TO AVOID CAUSING AN ACCIDENT UNTIL WE WERE ABLE TO COME TO A STOP. AFTER SEVERAL MILES THE POWER BRAKES HAVE NOT RETURNED. THERE IS OIL IN THE VACUUM LINE AT THE BOOSTER AND GAS MILEAGE YA BEEN POOR THE PAST FEW WEEKS PRIOR TO THIS. IT ALL POINTS TO A FAULTY VACUUM PUMP. 121,000 MILES ON THE TRUCK.

NHTSA ODI 11152958

TL* THE CONTACT OWNS A 2015 GMC YUKON. WHILE DRIVING AT LOW SPEEDS, THE BRAKES FAILED TO ENGAGE. THE BRAKE PEDAL BECAME EXTREMELY STIFF AND THE EMERGENCY BRAKE HAD TO BE APPLIED TO STOP THE VEHICLE. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOTIFIED AND REFERRED THE CONTACT TO NHTSA. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 47,200.

NHTSA ODI 11152408

I HAVE HAD AN ON-GOING ISSUE WITH THE STEERING, ELECTRICAL AND POWER STEERING AND STABILITY CONTROL. I HAVE HAD REPEATED ISSUES WITH THE STABILITY CONTROL TURNING OFF, SUDDEN DROP IN ELECTRICAL POWER, THE STEERING WHEEL GETS VIOLENTLY YANKED OUT OF YOUR HANDS AND SOMETIME THE CAR COMPLETELY CUTS OFF. FORTUNATELY MOST HAVE BEEN AT SLOW SPEEDS OR ELSE THE CAR WOULD HAVE FLIPPED. IT IS THE EXACT SAME ISSUE OTHER MODELS HAVE BEEN RECALLED FOR BUT MY VIN IS NOT INCLUDED IN THAT RECALL. I AM AFRAID OF THIS ISSUE KILLING ME OR MY LOVED ONES SHOULD IT HAPPEN AT SPEED OR LEAVE US STUCK IN FRONT OF ON COMING TRAFFIC. ACCORDING TO MY DEALER THIS IS AN ISSUE THE MANUFACTURE HAS KNOW ABOUT FOR A WHILE. *TR
