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

CIRCUIT BOARDS IN LED TAIL LIGHTS FAILING. THIS RESULTS IN SPORADIC FUNCTIONING BRAKE LIGHTS. THE DESIGN OF THE BUS BAR IN THE TAIL LIGHT HAS RESULTED IN CREATING WEAK SPOTS IN THE BUS BAR THAT CRACK AND UNLESS REPLACED OR REPAIRED AT SUBSTANTIAL COST THE BRAKE LIGHTS MAY OR MAY NOT FUNCTION PROPERLY.

NHTSA ODI 11254506

REPLACED DRIVER'S SIDE REAR LIGHTS ON 9-4-18. NOW, 9-10-19 NEED TO REPLACE PASSENGER SIDE REAR LIGHT. WAS STOPPED ON THE HIGHWAY AND TOLD LIGHT IS OUT.

NHTSA ODI 11254584

TAILLIGHT IS OUT ON MY VEHICLE. THE LIGHTS ARE LED AND THE CAR IS ONLY FOUR YEARS OLD. REPLACEMENT IS $500-750 FOR A TAILLIGHT!

NHTSA ODI 11253314

DRIVER SIDE BREAK LIGHT WORKS INTERMITTENTLY. AFTER RESEARCHING MULTIPLE OWNERS IN SIMILAR MODEL YEARS HAVE NOTED THE ISSUE BEING INSIDE OF THE LIGHT ITSELF HAVING AN ELECTRICAL ISSUE. BUT THE DEALERSHIP WANTS $750 FOR A NEW ONE WHEN THE PROBLEM IS WIDE SPREAD, NEEDS TO BE RECALLED AND MADE RIGHT.

NHTSA ODI 11252497

MY BRAKE LIGHTS ON MY 2015 YUKON DINALI WENT OUT ON THE RIGHT SIDE. I WAS INFORMED BY THE DEALERSHIP THAT THEY ARE NOT RESPONSIBLE FOR THIS AND NONE OF MY WARRANTIES WILL COVER IT.

NHTSA ODI 11252144

BRAKE LIGHT AND PARKING LIGHT QUIT WORKING. WENT TO DEALER AND THEY SAID YOU HAVE TO REPLACE THE WHOLE LED LIGHT ASSEMBLY. WOULD COST $850.00.

NHTSA ODI 11252260

PASSENGER SIDE REAR BRAKE LIGHT SUDDENLY STOPPED WORKING. IT IS AN LED LIGHT WHICH SHOULD NEVER HAVE TO BE REPLACED. OUR LOCAL GMC SERVICE DEPARTMENT SAID THAT IT IS THE 'DRIVER' ATTACHED TO THE LED BULB THAT IS FAULTY, BUT IT CANNOT SIMPLY BE REPLACED. THEY HAVE TO REINSTALL AN ENTIRE TAIL LIGHT WHICH APPARENTLY IS PRETTY COSTLY. I WAS QUOTED $925. AGAIN, NOTHING WRONG WITH THE LIGHT BULB ITSELF. SHOULDN'T COST $925 TO FIX.

NHTSA ODI 11251814

PASSENGER SIDE TAIL LIGHT HAS BEEN GOING OUT INTERMITTENTLY FOR MONTHS. SINCE THE PROBLEM BEGAN I'VE BEEN HAVING BATTERY ISSUES AND NOW BATTERY AND LIGHT ARE COMPLETELY DEAD. DEALER SAID IT WOULD BE $800 FOR LIGHT. THERE WAS NO INDICATOR/SENSOR THAT SHOWED THE LIGHT WAS OUT. I FOUND OUT BY ANOTHER DRIVER WHO PULLED UP NEXT TO ME AND TOLD ME. DRIVING AROUND I'VE SEEN MANY VEHICLES (SAME MODEL) WITH THE SAME ISSUE. THIS IS A SAFETY HAZARD, BECAUSE UNLESS SOMEONE TELLS US WE DON'T KNOW THE LIGHT IS OUT AND THEY ARE PREMATURELY GOING OUT. THE COST IS RIDICULOUS! THIS IS MY SECOND GMC AND I DID NOT HAVE ANY PROBLEMS LIKE THIS BEFORE. THIS IS THE CAR I DRIVE MY CHILDREN AROUND IN! IT IS APPARENT THAT IT IS A MANUFACTURER ISSUE. GMC NEEDS TO DO RIGHT BY ITS CUSTOMERS, BEFORE SOMEONE GETS HURT!

NHTSA ODI 11246432

DRIVER'S SIDE BRAKE LIGHT NOT WORKING. APPARENTLY A COMMON PROBLEM IN THESE YEAR YUKONS, AND GMC REFUSES TO ACKNOWLEDGE THE PROBLEM. REPAIR IS EXORBITANTLY EXPENSIVE, AND GMC SHOULD PAY FOR THE REPAIRS. THE VEHICLE ONLY HAS 50,000 MILES, AND HAS NEVER BEEN IN AN ACCIDENT.

NHTSA ODI 11246280

LED BRAKE LIGHTS WORK SOMETIME AND NOT AT ALL WHEN IN THE HEAT OF THE DAY. HAVE HAD A NUMBER OF PEOPLE COME TO ME IN PARKING LOTS AND TELL ME THAT THE BRAKE LIGHTS ARE NOT WORKING.

NHTSA ODI 11246294

BOTH BRAKE LIGHTS ARE OUT. IT'S BECAUSE OF A DEFECT IN DESIGN. THE METAL BRACKET THAT HOLDS THE BRAKE LIGHT LEDS IS CRACKED AND BREAKS THE CIRCUIT, THEREFORE THE LIGHTS WON'T WORK. LED LIGHTS SHOULD WORK FOR QUITE A LONG TIME. ONLY WAY TO FIX IT THROUGH THE DEALER IS TO REPLACE THE ENTIRE TAIL LIGHT ASSEMBLY TO THE TUNE OF APPROXIMATELY $1400 FOR BOTH LIGHTS. IT CAN BE REPAIRED BY CUTTING THE ASSEMBLY OPEN AND SOLDERING THE CRACK IN THE LED BRACKET. THERE ARE MANY INSTANCES OF THIS BEING REPORTED ONLINE. DEALERS DENY ENCOUNTERING THE PROBLEM. GMC IS NOT ADDRESSING THE ISSUE. THERE ARE REPORTED CASES ONLINE WHERE GMC YUKON OWNERS HAVE OF COURSE HAD THE REPAIRS MADE WITHIN WARRANTY WITH NO COST BUT AS SOON AS THE WARRANTY IS OUT AND THE PROBLEM REOCCURS, THEN THE OWNER HAS TO PAY APPROXIMATELY $700 PER LIGHT TO REPLACE THE TAIL LIGHT ASSEMBLY. THIS IS A SAFETY ISSUE, NO BRAKE LIGHTS CAN CAUSE SERIOUS WRECKS AND INJURY.

NHTSA ODI 11246197

FAULTY TAIL LIGHT. SOUNDS LIKE A COMMON PROBLEM ON 2015 GMC YUKON.

NHTSA ODI 11246237

BOTH LED TAIL LIGHT UNITS ON 2015 GMC YUKON FAILED WITHIN 6 MONTHS OF EACH OTHER. THE LED STRIPPING NO LONGER ILLUMINATES. EXACT SAME PROBLEM ON BOTH DRIVER AND PASSENGER SIDES OF VEHICLE. WAS INFORMED BY DEALERSHIP THE ONLY OPTION FOR REPAIR IS REPLACEMENT OF THE ENTIRE LIGHT AT A COST OF OVER $900 PER TAIL LIGHT.

NHTSA ODI 11246050

BRAKE LIGHTS WONT WORK ALL OF THE TIME.

NHTSA ODI 11245800

DRIVER SIDE BRAKE LIGHTS ONLY WORK INTERMITTENTLY. THE CIRCUIT ON THE LIGHT ASSEMBLY IS GOING BAD.

NHTSA ODI 11245935

TL* THE CONTACT OWNS A 2015 GMC YUKON. THE CONTACT STATED THAT THE PASSENGER SIDE BRAKE LIGHT WAS OUT. THE CONTACT ALSO STATED THAT THIS WAS THE SECOND TIME THE BRAKE LIGHTS WERE REPAIRED. THE VEHICLE WAS NOT TAKEN TO THE DEALER OR AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 80,000.

NHTSA ODI 11245413

TL* THE CONTACT OWNS A 2015 GMC YUKON DENALI. WHILE REVERSING THE VEHICLE, THE CONTACT WAS INFORMED THAT THE BRAKE LIGHTS WERE NOT ILLUMINATING. HOWEVER, WHEN THE VEHICLE WAS IN DRIVE, THE BRAKE LIGHTS ILLUMINATED. ALSO, WHEN THE CONTACT DEPRESSED THE BRAKE PEDAL TO SLOW OR STOP THE VEHICLE, THE BRAKE LIGHTS DID NOT ILLUMINATE. THE CONTACT CALLED COULTER BUICK GMC PHOENIX (1202 E CAMELBACK RD, PHOENIX, AZ 85014, (602) 396-5994) AND WAS INFORMED THAT THERE WERE NO RECALLS. THE DEALER REFERRED THE CONTACT TO THE MANUFACTURER. THE MANUFACTURER WAS NOT CONTACTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 64,000.

NHTSA ODI 11245472

THE DRIVER SIDE TAIL LIGHT STOPPED WORKING. THIS IS THE SECOND TIME THE LIGHT HAS STOPPED WORKI GON A VEHICLE WITH LESS THAN 60 THOUSAND MILES

NHTSA ODI 11244757

OVER THE LIFE OF OWING THIS NEW CAR, FROM MARCH 2016 TO JULY 2019, THE REAR PASSENGER AND DRIVER SIDE TAIL LIGHT ASSEMBLY HAVE EACH FAILED ONCE AND WERE REPLACED BY MY OWN EXPENSE. AGAIN FOR A THIRD TIME TOTAL, THIS MONTH THE PASSENGER SIDE TAILLIGHT ASSEMBLY REPEATED ITS FAILURE TO HAVE THE BREAK LIGHT TO FUNCTION. I FEEL THIS AMOUNT OF PART FAILURE INSIDE 3 YEARS IS TOO EXTREME AND IS DUE TO POOR DESIGN BY THE MANUFACTURER. THESE FAILED PARTS HAPPENED AT 16,000, 30,000 AND 50,000 MILES OF VEHICLE USE. NONE OF THE TAILLIGHT PARTS WERE EVER PHYSICALLY DAMAGED BEFORE. THE COST OF THE PART ALONE IS $795.00. THAT IS EVEN MORE REDICULOUS CONSIDERING A HOME LED BULB LASTS LONGER AND COSTS MUCH LESS.

NHTSA ODI 11244823

LEFT TAIL LIGHT IS INTERMITTENTLY FAULTY. BRAKE LIGHT ONLY WORKS INTERMITTENTLY.

NHTSA ODI 11244111

REAR LED TAILLIGHTS WORK INTERMITTENTLY. FOUND SEVERAL FORUMS WHERE THIS HAPPENS TO A LOT OF PEOPLE. IF YOU TAP THE TAILLIGHT IT SOMETIMES BEGINS WORKING AGAIN. TRUCK ONLY HAS 60K MILES AND GM WANTS OVER $1200 TO FIX (REPLACE BOTH TAILLIGHTS). EVIDENTLY THERE'S A CIRCUIT BOARD THAT GOES BAD INSIDE. I HAD THIS AT GM TO BE FIXED BUT BECAUSE TAILLIGHTS WERE WORKING AT THE TIME, THEY FOUND NO PROBLEM.

NHTSA ODI 11243894

THE REAR LED TAILLIGHTS ARE MALFUNCTIONING. THE PASSENGER BRAKE LIGHT WORKED INTERMITTENTLY FOR ALMOST 6 MONTHS WHILE BEFORE FAILING COMPLETELY, WHILE THE TAILLIGHT REMAINED WORKING. ANOTHER 6 MONTHS HAVE PASSED AND NEITHER THE BRAKE OR TAILLIGHT OPERATES. CURRENTLY, THE DRIVER SIDE BRAKE LIGHT WORKS INTERMITTENTLY. RESEARCH ON THIS PROBLEM SHOWS THAT THEY CAN BE CORRECTED, YET GMC DEALERSHIP HAS QUOTED $700 FOR EACH LIGHT ASSEMBLY.

NHTSA ODI 11243331

REAR BRAKE LIGHT ASSEMBLY FAILING TO LIGHT WHEN BRAKES APPLIED AND THERE IS NOT A NOTIFICATION TO THE DRIVER. THIS IS A MANUFACTURE FLAW WITH THE LED LIGHT CIRCUIT INSIDE THE ASSEMBLY. THERE IS NOT A LIGHT OUT NOTIFICATION SO THE DRIVER IS NOT AWARE THE BRAKE LIGHT HAS FAILED. THIS IS A SAFETY ISSUE AND IS AN WELL KNOWN ISSUE ON THE 2015-2019 YUKON. THIS IS OCCURRING OFTEN AND GMC IS HAVING PROBLEMS WITH SUPPLYING REPLACEMENTS BECAUSE THE DEMAND IS SO HIGH FROM THE FAILURE. GMC HAS ALSO RAISED THE PRICE OF THE BRAKE LIGHT BY 30% FROM $425 TO $675 NOT INCLUDING LABOR. I CALLED THE DEALER AND THEY INFORMED IT WAS A HIGH FAILING ITEM AND WAS ON BACKORDER AND NOT SURE WHEN THEY WOULD GET ONE. DRIVING THE VEHICLE WITHOUT PROPER BRAKE LIGHTS IS A SAFETY CONCERN AND NOT LEGAL SO LEFT WITH LITTLE OPTION BUT TO STOP DRIVING THE YUKON.

NHTSA ODI 11242951

REAR TAIL/BRAKE LIGHT FAILED AFTER FUNCTIONING INTERMITTENTLY FOR A MONTH. GMC DEALER REPLACED THE ENTIRE ASSEMBLY WITH A NEW GM PART AT A COST OF OVER $800. GMC DEALER EXPLAINED THAT DESPITE CHRONIC FAILURES OF THIS PARTICULAR PART, GM REFUSES TO RECALL. FAILURE APPEARS TO RESULT FROM A FAULTY CIRCUIT BOARD THAT CANNOT BE REPLACED OR REPAIRED EASILY. INTERMITTENT NATURE OF THE FAILURE IS AN UNSAFE CONDITION, ESPECIALLY AT NIGHT OR IN FOUL WEATHER.

NHTSA ODI 11242997

PURCHASED VEHICLE (USED) FROM DEALER LESS THAN 2 YEARS AGO. DRIVER TAILLIGHT WENT OUT. NOT COVERED UNDER WARRANTY BUT IS A SAFETY ISSUE THAT ACCORDING TO SEVERAL FORUMS IN A KNOWN PROBLEM. THE TAILLIGHT IS ARCHITECTED, ENGINEERED, AND BUILT IN SUCH A WAY AS TO BE VERY EXPENSIVE TO REPLACE, BREAK OFTEN, AND DISCOURAGE DIY OR NON-DEALER REPAIRS. THE VEHICLE WAS STATIONARY WHEN THE PROBLEM WAS NOTICED.
