What 606 owners told NHTSA about the 2015 GMC Yukon Denali Xl

LEFT BACK TAILLIGHT DEFECTIVE. IT WAS REPLACED BY GMC IN 2017 UNDER WARRANTY (BELOW 36,000 MILES) NOW AT 44000 IT FAILED AGAIN. LOTS AND LOTS OF PEOPLE POSTING THE SAME ISSUE ONLINE. BAD DESIGN OR JUST PLAIN BAD QUALITY.

THE ISSUE IS SO WELL KNOW THAT THERE ARE PEOPLE ON EBAY MAKING A BUSINESS TO REPAIR IT. A SIMPLE TYPE IN EBAY YUKON TAIL LIGHT WILL SHOW MULTIPLE LINKS.

BRAKE LIGHT IS NOT WORKING ON PASSENGER SIDE. WENT TO REPLACE BULB AND FOUND OUT THAT ONE HAS TO REPLACE THE ENTIRE TAILLIGHT ENSEMBLE WHICH IS $700-800. IT IS SAD THAT SOMETHING IMPORTANT TO SAFETY LIKE A BRAKE LIGHT HAS TO COST THAT MUCH TO REPLACE. I RESEARCHED AND FOUND THIS TENDS TO BE A COMMON PROBLEM. SO MUCH FOR LED LIGHTS--THIS IS ALSO POOR ENGINEERING!

REAR DRIVE SIDE BREAK LIGHT IS OUT BECAUSE OF POOR CONSTRUCTION.

BRAKE LIGHTS FOR PASSENGER REAR LAMP ASSEMBLY IS NOT WORKING. THIS IS THE SECOND TIME WITHIN 25 MONTHS THAT THIS HAS HAPPENED. THE ENTIRE LAMP ASSEMBLY NEEDS TO BE REPLACED AT A COST OF $600+. THE VEHICLE HAS LESS THAN 49,000 MILES, AND IT IS NO LONGER COVERED UNDER WARRANTY. ONLINE FORUMS INDICATE THAT THIS IS A COMMON PROBLEM WITH THE BRAKE LIGHTS IN THE LAMP ASSEMBLIES. IT APPEARS THE CIRCUIT BOARDS FOR THE LED BRAKE LIGHTS ARE BREAKING.

FAULTY BACK TAIL LIGHTS. THE ENTIRE ASSEMBLY FAILS WITH THE BACK BRAKE LIGHTS BEING OUT DUE TO FAULTY SOLDIERING AND PART. MAJOR SAFETY HAZARD. GM WILL NOT REPLACE.

NHTSA ODI 11186321

THE TAIL LIGHTS ARE FAULTY. THIS IS THE SECOND TIME I'VE HAD AN LED TAIL LIGHT GO OUT. SECTIONS OF THE LIGHTS COME ON AND OFF. ONE TAIL LIGHT ASSEMBLY HAS BEEN REPLACED ALREADY. THEY ALSO GET CONDENSATION ON THE INTERIOR OF THE ASSEMBLY. THIS APPEARS TO BE A COMMON THEME FOR A TAIL LIGHTS ON GM SUV'S FROM 2015-2018. THESE LIGHTS CAN BE PURCHASED FOR ANYWHERE BETWEEN $400. TO $900 RANGE FOR JUST ONE! THEY ARE ON A VEHICLE WHICH HAS A BASE PRICE OF OVER $50K AND LAST LESS THAN TWO YEARS! COME ON!

PASSENGER SIDE REAR BRAKE LIGHT WAS WORKING INTERMITTENTLY AND NOW HAS STOPPED WORKING ALL TOGETHER. THE BRAKE LIGHT UNIT IS A SEALED UNIT THAT CAN NOT BE SERVICED, IT MUST BE REPLACED ENTIRELY. VERY COMMON PROBLEM ON THIS MODEL DUE TO A FAULTY BRAKE LIGHT ASSEMBLY. FAILURE OF BRAKE LIGHTS PUTS THE SAFETY OF MY FAMILY IN JEOPARDY.

TAIL AND BRAKE LIGHTS FAILED. UPON INSPECTION IT WAS FOUND THAT THE CONDUCTIVE PLATE BETWEEN THE LEDS HAD CRACKED/BROKEN IN BOTH ASSEMBLIES.

ENGINE SHUTS OFF, STEERING ASSIST DISAPPEARS AND STEERING WHEEL IS JERKED OUT OF MY HAND, STABILITRAK WARNINGS ON DASH, HVAC SCREEN GOES BLANK, CHIMES START GOING OFF. THIS OCCURRED AS I WAS PULLING INTO A PARKING LOT AND I ALMOST HIT ANOTHER CAR. THE VEHICLE WAS MOVING AT NO MORE THAN 10MPH.

NHTSA ODI 11183932

THE BRAKE LIGHTS HAVE GONE OUT WITH ONLY 42000 MILES ON IT. I HAVE READ ON MESSAGE BOARDS ACROSS THE NATION THIS IS A MAJOR PROBLEM. DEALER WANTS 800 TO FIX IT.

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.

NHTSA ODI 11180836

ALL LED LIGHTS HAVE WENT OUT ON RIGHT SIDE, AS WELL AS BREAK LIGHTS. THIS IS A KNOW ISSUE TO GMC, AND YET THEY WILL NOT CORRECT IT. MY QUOTE TO HAVE IT FIXED WAS 2493.00 FROM LOCAL DEALERSHIP. THAT IS CRAZY. LED LIGHTS SHOULD LAST A WHOLE LOT LONGER THAN THIS. ALSO CONDENSATION IS IN THE FRONT HEADLIGHT WITH NO HOLES OR CRACKS. IF THIS HAPPENS WITH HOUSE WINDOWS, THEY ARE REPLACED BY THE MANUFACTURER. THERE ARE SO MANY COMPLAINTS, I WILL ALSO BE CONTACTING THE BETTER BUSINESS BUREAU. GMC KNOWS THERE IS A PROBLEM WITH THESE MODELS.

TAILLIGHTS WORKS INCONSISTENT NO BRAKE LIGHTS TOOK TO DEALER THEY SAID THE BOTH LIGHTS NEED TO BE REPLACED AND MY WARRANTY DOESN'T COVER IT THEY SAID THESE VEHICLES ARE KNOWN FOR HAVING THIS PROBLEM NEED FOR HELP WITH THIS

WIRING TO RADIATOR FAN CAUGHT ON FIRE. I WAS DRIVING THE CAR WHEN I SMELLED SMOKE. WHEN I PULLED OVER SMOKE WAS COMING FROM THE HOOD I OPENED THE HOOD AND THERE WAS OPEN FLAMES ON THE FAN WIRING WIRING.

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.

NHTSA ODI 11173673

WE BOUGHT OUR 2015 DENALI 1 YEAR AGO AND HAVE APPROX 50,000 MILES AND THE PASSENGERS SIDE TAIL LIGHT IS OUT. AFTER RESEARCHING TAILLIGHT PROBLEMS FOR MY MAKE AND MODEL THIS SEEMS TO BE A VERY COMMON ISSUE. THIS SHOULD BE CONSIDERED AS A RECALL BUT WHEN LOOKED INTO, I SEE IT IS NOT. ITS A SHAME TO SPEND SO MUCH MONEY ON A VEHICLE TO HAVE THE TAIL LIGHT OUT AT 3 YEARS (AFTER FACTORY WARRANTY IS ALREADY OUT) AND YOU HAVE TO REPLACE THE WHOLE TAIL LIGHT INSTEAD OF ONE PIECE.

NHTSA ODI 11172670

WE OWN A 2015 GMC YUKON WITH ONLY 51,000 MILES ON IT. THE REAR TAILLIGHTS ARE BOTH INTERMITTENT. SOMETIMES THEY WORK, SOMETIMES THEY DON'T. I RECENTLY TOOK THE VEHICLE INTO THE DEALERSHIP FOR SERVICE AND THEY SAID REPLACEMENT OF THE ENTIRE LIGHT WAS THE ONLY WAY TO FIX THE ISSUE. THEY ACKNOWLEDGED THAT THIS IS A KNOWN ISSUE AND THAT THEY HAVE SERVICED MANY VEHICLES WITH THE SAME ISSUE. THE SERVICE PERSON ADVISED THAT THERE IS A CIRCUIT THAT OVER TIME BREAKS AND THE CONNECTION BECOMES LOOSE. WHEN THE METAL TOUCHES AND A COMPLETE CIRCUIT IS MADE, THE LIGHT WILL TURN ON. WHEN IT DOESN'T TOUCH (FAULTY), THE TAILLIGHT AND BRAKE LIGHTS WILL NOT ILLUMINATE. THIS IS A MAJOR SAFETY HAZARD. A SIMPLE INTERNET SEARCH SHOWS THAT THIS ISSUE IS VERY COMMON AND GM DOESN'T APPEAR TO BE DOING ANYTHING TO ADDRESS IT. BECAUSE IT INVOLVES THE BRAKE LIGHTS, THIS IS VERY CONCERNING. NOT TO MENTION, THAT A REPLACEMENT IS $800. I HAVE ALREADY SPENT $800 FOR ONE SIDE, NOW THE OTHER SIDE IS OUT AS WELL. I FEEL THAT THIS SHOULD BE A RECALL ISSUE SINCE IT'S AN OBVIOUS SAFETY ISSUE THAT IS CAUSED BY FAULTY PARTS. HERE IS JUST ONE OF THE LINKS THAT DESCRIBE THIS ISSUE IN DETAIL: HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-T53845_DS768963
