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

THE REAR LIGHT WENT OUT. IT CANNOT BE FIXED WITH THE CHANGE OF A BULB. THE ENTIRE PIECE HAS TO BE REPLACED BECAUSE IT IS AN ELECTRICAL ISSUE. AFTER LOOKING ONLINE AND TALKING TO OTHERS WITH THE SAME MAKE AND MODEL, THIS IS A COMMON ISSUE WITH THIS MAKE/MODEL THAT NEEDS TO BE ADDRESSED AND GMC HELD ACCOUNTABLE.

THE REAR TAIL LIGHT SPORADICALLY QUITS WORKING. THERE APPEARS TO BE A SHORT OR MALFUNCTION IN THE LED LIGHT STRUCTURE. THIS OCCURS WHEN STOPPED AND IN MOTION. MALFUNCTIONING BREAK LIGHTS ARE A SERIOUS SAFETY CONCERN.

NHTSA ODI 11254876

BOTH DRIVE SIDE AND PASSENGER TAIL BRAKE LIGHTS NOT WORKING. ISSUE CAUSED BY THE LEDS BEING A 1 LARGE CHEAP CIRCUIT INSIDE THE UNIT. THE CIRCUIT CRACKS CAUSING THE LIGHTS NOT TO WORK.

ABOUT 2 WEEKS AGO THE VEHICLE HAD AN EXCELLENT RIDE, THEN ALL OF A SUDDEN IT HAD NO SUSPENSION AT ALL. IT RIDES EXTREMELY ROUGH AND I WOULD SAY VERY UNSAFE TO OPERATE

BRAKE LIGHT IS WILL NOT WORKING ON PASSENGER SIDE

NHTSA ODI 11255172

PASSENGER SIDE LED TAIL LIGHT STOPPED WORKING. SAW THAT THIS PROBLEM HAS BEEN REPORTED ON NHTSA MANY TIMES (OVER 400) BUT THERE HAS NEVER BEEN A RECALL. TO FIX THE TAIL LIGHT THE ENTIRE FIXTURE HAD TO BE REPLACED AT DEALER FOR A COST OF $900 WHICH IS RIDICULOUS. THIS IS A DEFINITE SAFETY HAZARD AS THERE WAS NO INDICATOR TO TELL ME THAT THE TAIL LIGHT AND BRAKE LIGHT WERE OUT! ONLY FOUND OUT ABOUT THE PROBLEM WHEN A FRIEND WAS FOLLOWING ME HOME AND TOLD ME ABOUT IT. SURPRISED THAT THERE HAS BEEN NEITHER A VOLUNTARY RECALL BY GM OR A MANDATED RECALL BY THE NHTSA. DEFINITELY NEEDS ADDRESSING. ALSO, THIS PROBLEM HAS BEEN REPORTED ON 2015-2017 YUKONS SO THERE APPEARS TO BE EITHER A DEFECTIVE PART OR BAD DESIGN.

THE PROBLEM I BEEN HAVING IS WITH THE STEERING. WHEN YOU TURN THE STEERING WHEEL SUDDENLY OR JUST KINDA FAST THE STEERING ASSIST WILL LOCK UP AND ALL OF THE DASHBOARD AND AC WILL SHUT OFF AND THAN RESTARTS. NOT ALL THE TIME BUT ABOUT 6 TIMES THE ENGINE SHUT OFF COMPLETELY. THIS IS A VERY SERIOUS AND DANGEROUS SITUATION THAT IT PUTS YOU IN THIS CAN HAPPEN WHEN STATIONARY WHEN YOU TRYING TO PULL OUT ON THE HIGHWAY OR AT SLOT SPEED WHEN TRYING TO TURN THIS HAPPENS ALL THE TIME

MY 2015 YUKON DENALI HAD A COMPLETE SUSPENSION FAILURE ON ALL FOUR TIRES AT 67,535 MILES. I WAS TOLD THIS WAS WAY TOO SOON TO BE HAVING SUSPENSION PROBLEMS ON THIS, BUT WHEN DIAGNOSED, THAT WAS THE ISSUE. I WAS TOLD BY MY AUTO REPAIR SHOP THAT IT WAS UNSAFE TO DRIVE IN THAT CONDITION, AS THE STEERING COULD FAIL TO WORK CORRECTLY WHEN GOING THROUGH TIGHT TURNS AND BRAKING. THEY SAID THAT IT COULD POSSIBLY SKID DUE TO NOT HAVING ANY SHOCKS OR STRUTS FUNCTIONING. WHEN THE VEHICLE WAS LIFTED, THE WHEELS DID NOT LOWER FROM THE CARRIAGE AT ALL DUE TO COMPLETE FAILURE OF THE SUSPENSION SYSTEM. WE REPLACED THE REAR SHOCKS AND FRONT STRUTS TO ADDRESS THIS ISSUE. THIS PROBLEM DID NOT OCCUR ALL AT ONCE, BUT RATHER OVER A PERIOD OF A COUPLE WEEKS WHEN THE VEHICLE STARTED TO RIDE ROUGHER ON EACH TIRE. ALL FOUR WENT OUT WITHIN A SPAN OF TWO WEEKS TIME.

ALL THE RUBBER WINDOW MOLDINGS ARE CURLING OUT UNDER PLASTIC TRIM BOTH TAIL LIGHTS WORK INTERMEDIATELY

NHTSA ODI 11254387

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.

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.

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

WHEN THE GAS PEDAL IS DEPRESSED FULLY, THE GAS PEDAL STICKS THE CAR CONTINUES ACCELERATING. THE PROBLEM BEGAN WITH INITIAL COMPLETE DEPRESSION OF GAS PEDAL TO CAUSE SOME ACCELERATION AND DEPRESSING BRAKE ALLOWED VEHICLE TO RETURN TO NORMAL DRIVING. THE PROBLEM HAS WORSENED OVER TIME TO THE POINT WHERE BOTH FEET DEPRESSING ON THE BRAKE PEDAL DID NOT AFFECT ACCELERATION AND CAUSED SMOKE TO EMIT FROM BOTH FRONT BRAKE PADS, AND THE PASSENGER FRONT BRAKE PAD FLAMED UP FROM THE HEAT. THE CAR WAS DRIVEN INTO A PARKING LOT WITH THE BRAKE DEPRESSED THE ENTIRE TIME, AND TURNED OFF. SO FAR, THIS HAS ONLY HAPPENED WHEN THE GAS PEDAL IS FULLY DEPRESSED. THE DEALER TOLD ME THE MAT CAUSED THIS EVEN THOUGH THE MAT IS CUT AROUND THE GAS PEDAL WITH PLENTY OF ROOM TO NOT OBSTRUCT PEDAL. THE MAT ALSO DOES NOT SLIDE OR MOVE ABOUT THE AREA. THE GMC DEALER TOLD ME THEY TOOK THE MAT OUT AND DID NOT NOTICE ANY AUTO ACCELERATION, AND THEY TOLD ME THEY WERE UNABLE TO DEPRESS THE GAS PEDAL FULL TO ATTEMPT TO RECREATE THE PROBLEM, TO NOT COMPROMISE THE SAFETY OF THE OTHER CARS NEARBY.

BRAKE LIGHT WORKING INTERMITTENTLY. MOST TIMES IT'S NOT WORKING. SOMETIMES IT DOES. STATIONARY AND IN MOTION.

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

RIGHT REAR LED TAIL/BRAKE LIGHT STOPPED WORKING. NOT EASILY FIXABLE. DEALERS ARE AWARE OF THE PROBLEM AND MAKE YOU PAY $700+ A PIECE FOR A WHOLE NEW ASSEMBLY. THE ISSUE APPEARS TO BE A FAULTY CIRCUIT BOARD INSIDE. THIS SHOULD BE SOMETHING THAT CAN BE TAKEN APART AND FIXED EASILY OR GM SHOULD REPLACE IT FOR FREE.

NHTSA ODI 11252998

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

I WAS INVOLVED IN A COLLISION WHERE MY VEHICLE ENDED UP IN A DITCH AND HIT A CEMENT CULVERT HEAD ON. THE STEERING WHEEL AIRBAG DIDN'T DEPLOY. ALL AIRBAGS ALONG THE SIDES OF THE VEHICLE DID, BUT NEITHER FRONT WERE ACTIVATED. ALTHOUGH I DIDN'T HAVE A PASSENGER IN THE VEHICLE, THERE WERE OTHER ITEMS IN THE SEAT THAT WERE QUITE HEAVY.

NHTSA ODI 11252186

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.
