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

REAR PASSENGER BRAKE LIGHT STOPPED WORKING. INTERNET SEARCHES INDICATE THAT IT IS A FREQUENT PROBLEM WITH MANY COMPLAINTS. MOST NOTABLE IS THE DEALER COST TO REPLACE - $600 - $800 PER FIXTURE DUE TO IT BEING A SEALED UNIT AFTER WARRANTY HAS EXPIRED. GM NEEDS TO FIX THIS PROBLEM. A RECALL IS DEFINITELY IN ORDER.

NHTSA ODI 11130348

THE BRAKE LIGHTS CONTINUOUSLY WORK AND THEN DON'T WORK. THERE IS A MALFUNCTION WITH THE BRAKE LIGHTS IN THESE CARS. PLEASE REPORT YOUR ISSUES SO GM CAN STOP ROBBING US.

I GIVE!!! NOW BREAK LIGHTS NOT WORKING!!! RIGHT BREAK LIGHT IS OUT AND LEFT DRIVER IS INTERMITTENT. VEHICLE HAS 37K ON IT AND WAS JUST PICKED UP FROM THE DEALER AFTER HAVING 1 OF MANY ISSUES THROUGH THE PAST YEAR RECTIFIED AND NOW THIS! THIS IS A SIGNIFICANT SAFETY HAZARD AND COULD TREMENDOUSLY INJURE SOMEONE. RIGHT NOW MY CAR CANNOT EVEN PASS INSPECTION DUE TO THE FAULTY EQUIPMENT INSTALLED BY THE MANUFACTURE THAT IS A DANGER TO MY SAFETY. I HAVE OWNED MANY GMC'S (6 TOTAL) THROUGH THE YEARS AND THIS BEING THE WORST!! THE LATEST, I HAVE HAD THE TORQUE CONVERTER REPLACED IN AUG 18 - DUE TO SHUDDERING AND VIBRATION. THEN THE STEERING COLUMN REPLACED DUE TO POPPING , BACK HATCH HINGE REPLACED DUE TO POPPING AND MALFUNCTION, BACK GLASS DOOR RUBBER GASKET REPLACED DUE TO LEAKING, SHARKFIN ANTENNA REPLACED DUE TO LEAKING, SUNROOF GASKET REPLACED DUE TO LEAKING, NEW TIRES AT 500 MILES DUE TO EXCESSIVE VIBRATION. BACK DOOR ADJUSTED DUE TO SLAMMING, AND ADDITIONAL SLIGHT ISSUES. THE RADIO HAS A CONSTANT GLITCH ON THE SCREEN SINCE DAY ONE THAT AFTER BEING TAKEN IN NUMEROUS TIMES, OF COURSE THE DEALER CANNOT REPLICATE THE PROBLEM AND KEEPS PERFORMING A FLASH UPDATE WHICH NEVER HELPS AND AS SOON AS I DRIVE OFF IT GLITCHES AGAIN. I HAVE CONTACTED GM REGARDING THE BRAKE LIGHTS, RADIO, AND NOW MY PASSENGER STEP IS MALFUNCTIONING NOT TO MENTION A RECALL WAS JUST RELEASED ON THE POWER STEERING. WILL THE REPAIRS EVER END? GUESS ONCE I TRADE IT IN ON ANOTHER MANUFACTURE AS THIS WILL MOST LIKELY BE THE LAST GMC I WILL EVER PURCHASE!! I DO NOT HAVE TIME TO LIVE MY LIFE AT THE DEALER FOR A HIGH END PURCHASE THAT IS THE WORST MISTAKE EVER!! NOT TO MENTION BEING A SAFETY HAZARD!!!

THE RIGHT REAR BRAKE LIGHT AND RUNNING LIGHT HAS GONE OUT. APPEARS TO BE A COMMON PROBLEM. YOU CAN'T REPLACE THE BULB LIKE OLDER CARS. YOU NEED TO REPLACE THE WHOLE BRAKE ASSEMBLY FOR $700!!! GM KNOWS ABOUT THE COMMON ISSUE BUT IS NOT COVERING IT.

MY DRIVERS SIDE TAIL LIGHT JUST WORKS INTERMITTENTLY WHEN I AM OUT ON THE ROAD DRIVING.

NHTSA ODI 11130024

MY RIGHT REAR TAIL LIGHT WORKS ON AND OFF FOR ABOUT A YEAR . I HAVE 41,000 MILES ON MY CAR AND NOW THE LEFT TAIL LIGHT GOES IN AND OUT ALSO SO I POTENTIALLY COULD HAVE TWO BRAKE LIGHTS OUT AT THE SAME TIME. I'VE SEEN SEVERAL OF THE SAME CAR IS ON THE ROAD WITH THE SAME PROBLEM GMC DENIES THE PROBLEM AND CHARGES $800 PER TAIL LIGHT TO FIX IT'S A HUGE SAFETY CONCERN AND I DON'T FEEL LIKE MY FAMILY IS SAFE AND I DON'T THINK WE SHOULD BE LIABLE FOR THEIR FAULTY LIGHT EQUIPMENT. THEY WON'T RECOGNIZE THEY ARE RESPONSIBLE FOR THE ISSUE IT'S COMPLETELY UNACCEPTABLE AND A HUGE SAFETY CONCERN. WHEN LOOKING UP THE PROBLEM ONLINE THERE ARE HUNDREDS OF PEOPLE WHO ARE HAVING THE SAME ISSUE WITH THE SAME MODEL CAR.

LED TAILLIGHTS AND BRAKE LIGHTS WORK INTERMITTENTLY ON BOTH DRIVER AND PASSANGER SIDE. PROBLEM HAS BEEN LONG TERM AND APPEARS TO BE FAILING MORE FREQUENTLY NOW.

REAR SIDE TAIL LIGHTS INTERMITTENTLY STOP WORKING

NHTSA ODI 11129202

REAR BRAKE LIGHT ASSEMBLY FOR BOTH THE LEFT AND RIGHT SIDE WORK INTERMITTENTLY. WE HAVE ALREADY REPLACED THE RIGHT SIDE FOR A COST OF $600.00 FOR THE LIGHT ASSEMBLY ONLY.

NHTSA ODI 11127995

REAR LEFT TAIL LIGHT AND BRAKE LIGHT WORK INTERMITTENTLY. YET STARTED HAPPENING AND CAR WILL NOT PASS INSPECTION IN THE STATE OF VA. WHEN NOTICED THE VEHICLE WAS PARKED, BUT HAVE ALSO SEEN WHILE DRIVING.

NHTSA ODI 11124662

FRONT RIGHT LED DAYLIGHT LIGHT IS OUT. CAR IS OUT OF WARRANTY, AND PART IS APPROXIMATELY $750 TO REPLACE, VICE JUST A BULB SWAP. CAR HAS ABOUT 90K MILES ON IT. LED DAYLIGHT IS NOT ABLE TO BE REPAIRED. I BELIEVE IT'S REFERRED TO AS DRL. DEALERSHIP WILL NOT REPLACE IN WARRANTY, BECAUSE CAR IS OUT OF WARRANTY - AND REPLACEMENT FOR A LIGHT IS OVER $700....ABSOLUTELY UNACCEPTABLE AND UNSUSTAINABLE. ESPECIALLY SINCE THIS MODEL IS A 2015 MODEL. OVER THE LIFE OF THIS VEHICLE, HOW MANY TIMES AM I EXPECTED TO REPLACE A $750 LED HOUSING?

NHTSA ODI 11123998

THE REAR LED BRAKE TAIL LIGHT STOPPED WORKING DUE TO A CRACK IN THE CONDUCTIVE PLATE INSIDE THE ASSEMBLY.

NHTSA ODI 11123801

PASSENGER SIDE REAR BRAKE LIGHT AND TAIL LIGHT STOPPED WORKING. THIS CANNOT BE FIXED WITH A SIMPLE BULB. THIS IS AN INTEGRATED LED REQUIRING THE ENTIRE TAIL LIGHT ASSEMBLY TO BE REPLACED AT THE OWNERS EXPENSE. DEALER ESTIMATE WAS $800 AFTER INSTALLING.

NHTSA ODI 11123287

MULTIPLE COMPLAINTS HAVE BEEN FILLED WITH GMC ABOUT THEIR POOR BRAKE DESIGN ON THEIR 2015- 2019 YUKONS THE CIRCUIT BREAKS AND THE TAIL LIGHT ASSEMBLY QUITS WORKING. YUKON SAYS THEY HAVE NOT HEARD OF SUCH COMPLAINTS. AND WILL NOT RECALL THEIR POOR ASSEMBLY DESIGN.

NHTSA ODI 11123144

DRIVERS SIDE TAILLIGHT STOPPED WORKING. SIGNAL STILL OPERATING.

NHTSA ODI 11122286

TAIL LIGHT NO LONGER WORKING. SAFETY HAZARD. IT STARTED FLASHING INTERMITTENTLY AND SMELLING FUNNY NOW IT WON'T WORK AT ALL. THIS WILL CAUSE AN ACCIDENT AND OF COURSE IT'S NOT UNDER WARRANTY AS I'M AT 60K BUT GMC WILL DO NOTHING FOR IT EVEN THOUGH THIS IS A WIDELY KNOWN ISSUE. I CONTACTED THEM AND THEY WILL DO NOTHING!

NHTSA ODI 11121900

BRAKE LIGHTS HAVE FAILED. I APPEARS TO BE DUE TO A FAULTY SOLIDER ON THE LED ASSEMBLY. BOTH BRAKE LIGHTS HAVE NOW FAILED. THE FAULT IS CONSTANT AND HAS NO RELATIONSHIP TO STATUS OF THE OPERATION OF THE VEHICLE OR ROAD CONDITIONS. CONSUMER CAN NOT REPAIR THE FAULT DUE TO THE DESIGN OF THE TAIL LIGHT ASSEMBLY. THE VEHICLE OWNER AND OTHER DRIVERS ARE BEING ENDANGERED BY THIS ISSUE THAT IS OBVIOUSLY A QUALITY ISSUE WITH THE PRODUCT.

NHTSA ODI 11121588

BOTH BRAKE LIGHTS FAILED WITHIN DAYS OF EACH OTHER. THE FAILURE WAS THE SAME AS INDICATED HERE: HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-T53845_DS768963 . I HAVE PICTURES OF THE FAILED PIECE.

AFTER ABOUT 1 YEAR OF OWNING THIS VERY EXPENSIVE VEHICLE (BOUGHT IT WHEN IT WAS ABOUT 2 YEARS OLD, IE. 2017) USED FROM A GMC DEALER - THE DRIVERS SIDE TAIL LIGHT STARTED WORKING ONLY INTERMITTENTLY AND THEN STOP WORKING ALL TOGETHER. I HAD THE DEALER ESTIMATE THE REPLACEMENT COST AND THEY TOLD ME IT WOULD BE $1,500 TO REPLACE BOTH TAIL LIGHTS (SAID I NEEDED TO REPLACE THE ENTIRE ASSEMBLY BECAUSE THEY WERE LED????). THIS IS ABSURD ON SO MANY LEVELS...THESE ARE ONE OF THE MOST EXPENSIVE VEHICLES ON THE MARKET AND WITHIN ONLY A FEW YEARS THE TAIL LIGHTS NEED TO REPLACED...AT AN OUTRAGEOUS COST. MY LAST YUKON (2007) DIDN'T HAVE A TAIL LIGHT GO OUT FOR MANY YEARS...AND I BOUGHT A REPLACEMENT BULB FOR $3 AND DID IT MYSELF. AFTER DOING SOME RESEARCH, IT APPEARS TO BE A "COMMON" ISSUE FOR THESE GMC VEHICLES...AND THE FACT THAT GMC IS WELL AWARE OF THIS IS DOING NOTHING ABOUT A KNOWN AND PERSISTENT ISSUE IS FRUSTRATING.

NHTSA ODI 11120090

TAILIGHT BRAKE LIGHT NOT WORKING, NO REPLACEMENT BULB AVAILABLE, GM SAYS MUST BE ENTIRE UNIT AND HOUSING FOR $701. THIS IS RIDICULOUS AND ONEROUS. THIS IS CLEARLY A DEFECTIVE DESIGN AND DEFECTIVE PART. SHOULD BE REPLACED OR REPAIRED FOR FREE.

NHTSA ODI 11120100

RIGHT TAIL LIGHT BEGAN TO NOT WORK LAST FALL. I WENT TO HAVE IT CHECKED THEN IT WAS WORKING FINE. WENT IN FOR ABOUT A MONTH. SOMETIMES IT WORKED THEN IT WASN'T. ALMOST LIKE IT HAD A SHORT. EVENTUALLY HAD TO REPLACE WHOLE SYSTEM NOT JUST A BULB. NOW ALMOST ONE YEAR LATER THE SAME THING IS HAPPENING ON THE LEFT SIDE. THIS IS A $1,000 ITEM. I HAVE OWNED CARS FOR TEN YEARS AND NEVER HAD TO REPLACE A LIGHT. READ ONLINE THAT THERE ARE MANY ISSUES WITH THESE TAIL LIGHTS.

NHTSA ODI 11119832

BAD LED BRAKE LIGHTS: WE PURCHASED OUR GMC YUKON XL 2015 IN MAY 2016. SINCE THEN WE HAVE HAD TO REPLACE BOTH BRAKE LIGHTS(1 AFTER A YEAR-MARCH 2017 AND THE 2ND AFTER 2 YEARS-AUG 2018) AND HAVE HAD THE VEHICLE ONLY 2 YEARS. THEY ARE LED LIGHTS SO NOT A CHEAP REPAIR. QUOTED COST $750-$2000. SO FAR, OUR WARRANTY HAS COVERED THE REPAIRS BUT ONCE WARRANTY IS OFF, IT WILL COST TOO MUCH TO REPAIR AND IS NOT SAFE TO DRIVE WITHOUT REPAIRING! WE HAVE HAD MANY VEHICLES OVER THE YEARS AND HAVE ONLY REPLACED BRAKE LIGHTS 2-3 TIMES AND FOR LESS THAN $25 EACH TIME. THIS APPEARS TO BE A BAD DESIGN OR FAULTY PARTS BY GMC. ONE OF THE FAILURES WAS DUE TO INTERNAL SHORT IN THE LED MODULE. WE WOULD LIKE GMC TO RESOLVE THE FAULTY PARTS AND RECALL THE PART AND FULLY REPLACE OUR BRAKE LIGHTS WITH RELIABLE LIGHTS VS LIGHTS THAT ONLY LAST A YEAR. THANK YOU!

2015 YUKON BRAKE LIGHT NEEDS RECALL" DOES NOT WORK ...IT'S A KNOWN ISSUE AND AN EXPENSIVE FIX. NEED HELP THIS IS

NHTSA ODI 11119558

BOTH REAR TAIL LIGHTS (BRAKE AND RUNNING LIGHTS) ARE NOT FUNCTIONING PROPERLY. THE PASSENGER SIDE ISN'T WORKING ALL TOGETHER AND THE DRIVERS SIDE WILL SOMETIMES BE ON AND OTHER TIMES NOT. THE DEALERSHIP WANTS $679 EACH SIDE FOR REPLACEMENTS. THIS SEEMS LIKE QUITE A BIG EXPENSE FOR A SAFETY ISSUE THAT GM NEEDS TO ADDRESS.

NHTSA ODI 11119597

REAR TAIL LIGHT FAILED, WAS REPLACED AND FAILED AGAIN 2 MONTHS LATER. VERY EXPENSIVE REPAIR FOR CONTINUED MALFUNCTION. NO BREAKLIGHTS, NO TURN SIGNAL, NO WARNING. DISCOVERED BY OTHER DRIVERS NOTIFYING ME ON THE ROAD.
