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

REAR TAILLIGHT RANDOMLY GOING ON AND OFF. INTERIOR LIGHT RANDOMLY FLICKER, THEFT DETERRENT SYSTEM OFTEN ACTIVATES, VEHICLE DASH SYSTEMS RANDOMLY RESET AND MOST RECENTLY VEHICLE STEERING WHEEL LOCKED AND CAR TURNED OFF WHILE I WAS DRIVING WITH MY KIDS IN THE CAR AND IN A SCHOOL ZONE!!!!! THIS COULD HAVE BEEN TRAGIC AND WAS VERY SCARY!!!!

NHTSA ODI 11218199

VEHICLE BRAKES FEEL LIKE THEY LOCK UP OFTEN I HAVE TO PUSH AS HARD AS I CAN, THE DASH SAYS "BRAKE ASSIST" OR SOMETHING WHEN THEY FEEL LIKE THEY LOCK UP. I'VE ALMOST HIT CARS SEVERAL TIMES BECAUSE THEY LOCK UP LIKE THIS AND THERES NOTHING I CAN DO. HAPPENS OFTEN AND VARYING SPEEDS 10-70!

NHTSA ODI 11218202

THE REAR TAIL LIGHTS WORK PERIODICALLY. I'VE ALREADY REPLACED THE LEFT SIDE AND NOW THE RIGHT SIDE HAS WENT OUT. COST IS $750 TO REPLACE. I AM CURRENTLY HAVING TO WAIT ON A TAIL LIGHT BECAUSE THEY ARE BACKORDERED DUE TO SO MANY OTHERS HAVING SAME PROBLEM (ACCORDING TO DEALER). IT WILL WORK PERIODICALLY AT FIRST BUT IF THIS IS LIKE THE PREVIOUS, IT WILL EVENTUALLY QUIT WORKING ALL TOGETHER. SOMETIME THE BOTTOM HALF IS LIT BUT NOT THE WHOLE LAMP. DEALER COULDN'T TELL ME IF THEY HAD FIXED THE PROBLEM OR IF I WILL BE GETTING ANOTHER FAULTY PART.

MY REAR PASSENGER SIDE TAIL LIGHT RANDOMLY WORKS. NO RHYME NOR REASON. WE NOTICED THIS AFTER BCM WAS REPLACED.

REAR LED TAILLIGHTS INTERMITTENTLY FAIL DUE TO WEAK CIRCUIT BRIDGE DESIGN

NHTSA ODI 11217373

MY TAILLIGHT ASSEMBLY LED LIGHTS HAVE GONE OUT. I'VE READ ABOUT THIS ISSUE AND IT'S A COMMON ISSUE WITH THIS VEHICLE AND THE DEALER CHARGES CLOSE TO $1000 PER LIGHT TO REPAIR THIS ISSUE.

NHTSA ODI 11217429

BOTH LED TAILLIGHTS FAILED WITHIN ONE MONTH ON A TRUCK WITH LESS THAN 25000 MILES.

NHTSA ODI 11217284

WE HAVE HAD BOTH OUR TAILLIGHTS FAIL. THE BLINKERS STILL FUNCTION BUT BECAUSE THEY ARE LED THEY SAY THEY MUST REPLACE THE WHOLE UNIT. EACH SIDE COST $672. THAT IS OUTRAGEOUS FOR A TAILLIGHT. THERE NEEDS TO BE A WAY TO REPLACE EACH PIECE.

TL* THE CONTACT OWNS A 2015 GMC YUKON DENALI XL. WHILE ATTEMPTING TO SHIFT THE VEHICLE FROM PARK INTO DRIVE, THE TRANSMISSION MADE A HARD CLUNKING SOUND. ALSO, WHILE DRIVING BETWEEN 30-50 MPH, THE VEHICLE VIBRATED ABNORMALLY. THE VEHICLE WAS TAKEN TO LEWIS CHEVROLET BUICK OF LIBERAL (LOCATED AT 202 N GRANT AVE, LIBERAL, KS 67901, (620) 624-2584) WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION FLUID NEEDED TO BE FLUSHED AND REFILLED. THE VEHICLE WAS SERVICED, BUT THE FAILURE PERSISTED. THE MANUFACTURER WAS CONTACTED. THE FAILURE MILEAGE WAS UNKNOWN.

NHTSA ODI 11210540

VEHICLE HAS UNDER 45,000 MILES AND BOTH HEADLIGHTS NEED TO BE REPLACED DUE TO MALFUNCTIONING LED'S FROM WATER INTRUSION. THIS HAPPENS AFTER WASHING MY CAR AND NOW IT WILL NOT PASS STATE INSPECTION DUE TO DRIVER SIDE DAYTIME LED NOT TURNING ON, AND PASSENGER SIDE DRL NOT TURNING OFF. I CAN NOT GET THIS FIXED BECAUSE THE PASSENGER SIDE LIGHT IS ON BACKORDER, YET MY LOCAL DEALER SAID THIS ISN'T A KNOWN PROBLEM. TAKE A LOOK ON THE INTERNET AND IT'S CLEARLY A MANUFACTURING ISSUE (HENCE BACKORDERED HEADLIGHTS)

NHTSA ODI 11210566

DRIVER SIDE TAIL LIGHT WOULD INTERMITTENTLY GO IN AND OUT FROM WORKING AND NOT WORKING. THE TAIL LIGHT WOULD DO THIS WHILE IN MOTION, WHILE STATIONARY, IT DID NOT MATTER. THE LOCAL DEALERSHIP THAT WE BOUGHT IT FROM SAID WE WOULD NEED TO REPLACE IT. OVER $750. NOW THE PASSENGER SIDE TAIL LIGHT IS DOING THE EXACT SAME THING. HUGE SAFETY HAZARD. CLEARLY A FAULTY PART, NOT JUST A BULB GOING OUT, BUT THE ENTIRE ELECTRICAL DESIGN OF THE THE TAIL LIGHT IS FLAWED. GM CHARGES YOU TO REPLACE THE ENTIRE HOUSING WITH THE SAME EXACT FAULTY PART THAT WAS ON THERE BEFORE.

NHTSA ODI 11210264

REAR TAIL LIGHTS STOP WORKING ALL OF THE SUDDEN. LEFT AND RIGHT SIDE.

NHTSA ODI 11210136

THE VEHICLE WILL OFTEN SHIFT UNPREDICTABLY. MOVING FROM A DEAD-STOP, THE VEHICLE WILL SOMETIMES DEMONSTRATE SIGNIFICANT HESITATION (TO SHIFT) FOLLOWED BY A LOUD AND VIOLENT ENGAGEMENT. IN SOME INSTANCES THE VEHICLE FEELS LIKE IT HAS BEEN HIT BY ANOTHER VEHICLE. THE AUTOMOBILE WILL SHUDDER AND SLIP AND JERK WHEN IT SHIFTS BETWEEN GEARS. THE VEHICLE IS UNSAFE TO OPERATE. THE DEALER CAN NOT FIX THE ISSUE, BUT UNDERSTANDS THE VEHICLE PROBLEMS.

NHTSA ODI 11209746

BOTH REAR LIGHT ASSEMBLIES HAVE HAD ISSUES. DRIVERS SIDE WAS FIRST, BRAKE LIGHT STOPPED WORKING. REPLACED UNDER WARRANTY. PASSENGER SIDE BRAKE LIGHT AND PARKING LIGHT HAVE NOW STOPPED WORKING, JUST OUT OF WARRANTY. PROBLEM COMES AND GOES DEPENDING ON TEMPERATURE. I WOULD THINK THIS WOULD BE CONSIDERED A SAFETY ISSUE AND BE THE SUBJECT OF A RECALL SINCE IT IS WIDE SPREAD.

NHTSA ODI 11209404

FOR THE PAST 6 MONTHS I HAD BEEN GETTING REPORTS THAT MY PASSENGER SIDE TAIL LIGHT WASN'T WORKING- WHEN WE CHECKED IT IT WAS... FINALLY SOMEONE TOLD ME IT GOES ON AND OFF. MY YUKON WAS GOING INTO THE DEALERSHIP FOR THE POWER STEERING RECALL AND I ASKED THEM TO CHECK. THEY REPLACED THE WHOLE LIGHT AT $800!!! A QUICK INTERNET SEARCH SHOWS THIS IS A COMMON PROBLEM.

NHTSA ODI 11209362

THIS IS THE SECOND TAILLIGHT TO FAIL. THE PASSENGER SIDE FAILED AT 35,500 MILES IN OCTOBER 2018. THE DRIVER SIDE HAS NOW FAILED AT 39,000 MILES AND 4 MONTHS LATER. THESE PARTS COST $800 EACH TO REPLACE. A MAJOR REPAIR COST ON A VEHICLE WITH ONLY THIS MUCH MILEAGE. A DESIGN PROBLEM OBVIOUSLY EXISTS AND THIS PROBLEM IS A SAFETY HAZARD!!! JUST WAITING FOR A CRASH TO HAPPEN TO START A CLASS ACTION LAW SUITE.

NHTSA ODI 11208924

BOTH LED TAIL LIGHT FIXTURES WENT OUT AT ONCE, BOTH NON FUNCTIONING. HAVE TO REPLACE BOTH FIXTURES COSTING OVER $1400 FROM A GM DEALERSHIP.

NHTSA ODI 11209105

PULLING INTO PARKING SPOT LOW SPEED BRAKING POWER WAS LOST.. HARD BRAKE PEDAL.

NHTSA ODI 11208608

FAULTY REAR BRAKE LIGHTS. THE RIGHT LED MODULE FAILED, AND WAS REPLACED. THEN THE LEFT LED MODULE FAILED ABOUT A YEAR LATER. NOW THE REPLACED RIGHT LED MODULE HAS FAILED FOR A SECOND TIME! EACH REPAIR IS APPROX $650.00 FOR A 'DO IT MYSELF' REPAIR. THESE LED MODULES SHOULD LAST FOR THE LIFE OF THE VEHICLE AND NOT FAIL. WIDELY NOTED AS BEING A DEFECTIVE DESIGN. GM SHOULD REDESIGN AND MAKE GOOD ON REPAIRS BEYOND THE STANDARD WARRANTY FOR THOSE OF US THAT ARE OUT OF POCKET.

NHTSA ODI 11208619

PASSENGER SIDE BRAKE LIGHT STOPPED WORKING

NHTSA ODI 11208226

TAIL LED LIGHTS AND BRAKE LIGHTS STOPPED WORKING THEN START WORKING PARTIALLY THEN BACK TO NOT WORKING, WENT TO HAVE THEM REPLACED AND IT COST $1500.00 AND THEN 6 MONTHS LATER BACK TO PARTIAL WORKING TAIL LED LIGHTS AND BRAKE LIGHT THEN A SMALL STRIP OF THEM WORKING THEN NOTHING AT ALL THEN BACK TO WORKING THEN BACK TO NO LIGHT PERMANENTLY AGAIN!!

NHTSA ODI 11208327

I PURCHASED MY 2015 YUKON IN 8/2016 AND IN THE BEGINNING OF 2017 THE TAIL LIGHT ON THE RIGHT SIDE BURNT OUT THE BRAKE LIGHT DID NOT WORK DURING THE DAY BUT AT NIGHT IT WOULD WORK . I TOOK IT TO THE DEALERSHIP AND THEY TOLD ME THE LED LAMP HAD GONE AND NEEDED TO BE REPLACE . I CAME FIND OUT THIS LAMP IS ALL ONE PART AND THE COST FOR A SUPPOSEDLY IS OVER $600 JUST THE LAMP . SO I HAD TO BUY THE LAMP AND REPLACED IT MYSELF BUT THEY ASKED ME FOR THE CORE . SO THIS WAS IN 2917 AND NOW TWO YEARS LATER THE SAME LIGHT THAT BROUGHT BRAND NEW IN 2017 IS OUT AGAIN AND I'M HAVING TO SPEND ANOTHER 600 TO REPLACE IT AGAIN. I FEEL SOMETHING SHOULD BE DONE TO HELP THE CONSUMER BECAUSE GM DOES NOT CARE ABOUT THIS AND HOW IT AFFECTS THE VONSUR . CAN SOMETHING BE DONE ?

NHTSA ODI 11208372

WE PURCHASED A USED 2015 YUKON DENALI LESS THAN 6 MONTHS AGO AND BOTH TAIL LIGHTS HAVE NOW GONE OUT. AFTER READING ABOUT THE ISSUE, IT SEEMS LIKE THIS IS A VERY COMMON ISSUE WITH LIGHTS ON THIS VEHICLE. VERY UNFORTUNATE THAT GMC REFUSES TO DO ANYTHING ABOUT IT.

NHTSA ODI 11207958

THE MOST DISTURBING CONCERN IS THE FACT THAT I LOST MY BRAKES AS A RESULT OF A KNOWN PROBLEM THAT GM HAS EVEN RECOGNIZED RELATING TO A FAULTY VACUUM BOOSTER PUMP. I INCURRED A $500 REPAIR BILL DESPITE GM'S ACKNOWLEDGEMENT OF THE PROBLEM AND WILLINGNESS TO PAY FOR CARS WITH LESS THAN 70000 MILES. UNFORTUNATELY, MINE WAS OVER THE ALLOWABLE MILEAGE. ADDITIONALLY, I AM LOOKING AT A $1500 REPAIR BILL FOR A SEALED HEADLIGHT REPLACEMENT AND ANOTHER $300 BILL FOR A SIDE DETECTION SYSTEM ( LANE DEPARTURE WARNING). GM MADE A POOR CAR THAT IS UNSAFE AND IS NOT PROPERLY ADDRESSING THE PROBLEM.

NHTSA ODI 11208132

PASSENGER BREAK LIGHT INTERMITTENTLY WORKS. TOOK TO GMC THEY SAID THERE IS NO KNOWN ISSUE WHICH IS A LIE! HUNDREDS OF OWNERS ONLINE HAVING THE SAME ISSUES. THEY SAID THEY CAN'T NAIL DOWN THE ISSUE SINCE THERE'S CLEARLY POWER THERE. THEY WANT ME TO BUY A WHILE TAIL LIGHT ASSEMBLY! ABOUT 900 DOLLARS FOR THE SAME FAULTY PART!
