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

REAR BRAKE LIGHTS WORK INTERMITTENTLY. WHEN TAKEN TO THE DEALER THEY SAY THEY CAN'T FIND THE PROBLEM. IT IS A SAFETY ISSUE AND A COMMON ISSUE AMONG THESE CARS. IT IS HORRIBLE THAT GM WILL NOT FIX THIS PROBLEM FOR FREE. *TR

REAR BRAKE LIGHTS ASSEMBLY FAILURE (LEDS) BOTH DRIVER AND PASSENGER. COMMON FAILURE KNOWN TO GMC YUKON CUSTOMERS. *TR

NHTSA ODI 11324247

REAR TAIL LIGHTS NOT WORKING. BOTH TAIL LIGHTS REQUIRE REPLACEMENT. THERE IS AN OPEN RECALL FOR 2016 GMC YUKON'S WHY IS THERE NOT AN OPEN RECALL FOR 2015? THIS IS OBVIOUSLY AN ISSUE BASED ON THE NUMBER OF COMPLAINTS MADE / REPORTED HERE. *TR

NHTSA ODI 11324170

REAR TAIL LIGHT STOPPED WORKING GOING ON AND OFF AND ACCORDING TO THE AUTO ELECTRICIAN MY VEHICLE COULD HAVE GOTTEN ON FIRE DUE TO THE FAULTY LIGHTS. UPON SEARCHING FOR ANSWERS TO WHY MY VEHICLE'S BACK LIGHTS WERE NOT WORKING, I CAME UPON MANY OTHER CONSUMERS EXPERIENCING THE SAME ISSUE. NOT ONLY IS THE COST TO REPLACE THE LAMPS SO HIGH, WE RISK IN DRIVING A VEHICLE THAT COULD CATCH FIRE FOR SUCH CHEAPLY MADE LIGHTS. AND I STATE THIS BECAUSE THE AUTO ELECTRICIAN SAID THAT THE WIRE WOULD HEAT UP WHILE DRIVING THE VEHICLE AND CAUSE FURTHER DAMAGES TO MY YUKON. WHILE DRIVING, YOU CAN HEAR A CLEAR CHIRPING NOISE THAT IS PRODUCED WHEN YOU BRAKE. THIS ALSO HAPPENS WHILE THE VEHICLE IS STATIONARY. *TR

BREAK LIGHT INTERMITTENTLY ILLUMINATES ON DRIVER'S SIDE. RECEIVED LETTER FROM GMC DATED DECEMBER 2019, "INTENDED TO MAKE YOU AWARE THAT SOME 2015 MODEL YEAR GMC YUKON XL VEHICLES MAY HAVE A CONDITION WHERE THE BRAKE LIGHTS INTERMITTENTLY DO NOT ILLUMINATE". THE WOULD REPAIR IT WITH NO COST ONLY IF THIS WOULD HAVE OCCURRED WITHIN 6 YEAR OF THE DATE YOUR VEHICLE WAS ORIGINALLY PLACED IN SERVICE OR 72,000 MILES. OF COURSE, WE ARE WAY ABOVE THAT. DEALER QUOTED $800 COST REPAIR.

THE PASSENGER TAIL LIGHT WAS ONLY WORKING INTERMITTENTLY SO I HAD THE WHOLE THING REPLACED FOR $750. NOW MY DRIVER SIDE ONE IS ONLY WORKING INTERMITTENTLY. ALSO MY PASSENGER HEADLIGHT STARTED ACCUMULATING MOISTURE AND NOW THE WHOLE LED STRIP DOESN'T WORK. THERE HAS TO BE AN ISSUE WITH THE COMPANY MAKING THEM!

NHTSA ODI 11322121

THE PASSENGER SIDE BRAKE LIGHT WILL NOT ILLUMINATE. I'M NOT EXACTLY SURE WHEN IT BEGAN, WHEN I FIRST FOUND OUT IT WOULD SOMETIMES WORK AND SOMETIMES NOT, NOW IT HAS BE STAYING COMPLETELY OFF.

NHTSA ODI 11321871

BOTH TAIL LIGHTS (BRAKE LIGHTS AND RUNNING LIGHTS IN RED) STOP WORKING WITH NO WARNING TO THE DRIVER. THIRD BRAKE LIGHT DOES CONTINUE TO WORK. THIS IS NOTICED WHEN PARKED AND WHEN IN MOTION. THIS IS A SAFETY ISSUE FOR OTHER DRIVERS CRASHING INTO OUR VEHICLE BECAUSE THEY DO NOT KNOW THAT WE ARE BRAKING. A FRIEND HAD TO POINT THIS OUT TO US IN THE SCHOOL PICKUP LINE. FIRST NOTICED ON 2/13/20. HAD TO BUY TWO NEW TAILLIGHT ASSEMBLIES AND INSTALL.

THE REAR TAIL LIGHT LED HAS MALFUNCTIONED AND WILL NOT WORK OR WORKS INTERMITTENTLY.

NHTSA ODI 11317186

NO BRAKE LIGHT IN BOTH REAR LIGHTING ASSEMBLIES. STARTED WITH THE PASSENGER SIDE AND NOW THE DRIVERS SIDE. GMC ISSUED A LETTER IN DECEMBER 2019 STATING THEY'D PAY FOR REPAIRS IF VEHICLE IS LESS THAN 6 YEARS OR 75,000 MILES WHICH EVER COMES FIRST. WE'LL I'M OVER ON BOTH. GMPP EXTENDED WARRANTY DOESN'T COVER THIS REPAIR. SPEND $75K FOR THIS TRUCK AND NOW THIS.

BOTH TAIL LIGHTS STOPPED WORKING ON THE FREEWAY DURING MY TRIP TO SAN DIEGO FROM PHOENIX. ABOUT HALFWAY HERE ONE TAIL LIGHT WENT OUT IN ABOUT 20 MILES LATER THE OTHER ONE STOPPED WORKING. I KNOW THIS BECAUSE A FRIEND WAS FOLLOWING ME.I CALLED THE DEALERSHIP, HE STATED THAT THE TAIL LIGHTS ARE ON NATIONAL BACKORDER AND WON'T BE IN FOR A WEEK PLUS. NOW I AM DRIVING AROUND CALIFORNIA WITH NO BRAKE LIGHTS.. I ONLY HAVE 48,000 MILES ON THIS SUV, EACH TAIL LIGHT IS $760 THE ONLY WAY TO REPAIR THIS IS TO REPLACE THEM. THANK YOU GM I WILL BE FORWARDING YOU MY TICKET..

FIRST, PASSENGER SIDE TAIL LIGHT WAS GOING ON AND OFF. SOMETIMES THE WHOLE PANEL WOULD NOT TURN ON. THEN, A FEW WEEKS LATER THE OTHER TAIL LIGHT STARTED DOING THE SAME THING AND NOW BOTH BRAKE LIGHTS DO NOT COME ON. THEY WILL SPORADICALLY START WORKING AGAIN EVER SO OFTEN.

GMC RECENTLY ADVISED US THAT THE TAILGATE LIGHTS HAVE HAD PROBLEMS WHERE THEY "INTERMITTENTLY" DO NOT ILLUMINATE. WE HAVE HAD THIS ISSUE FOR QUITE SOMETIME WHERE DRIVERS CANNOT SEE OUR TAILGATE LIGHTS WHEN THE PROBLEM OCCURS. BECAUSE IT HAS BEEN INTERMITTENT, IT HAS BEEN VERY HARD FOR THE SHOP TO DIAGNOSE AS WHEN THEY GET IT AND IT IS ON, THEY CAN'T FIGURE OUT WHAT IS WRONG WITH IT. SINCE WE RECEIVED THE LETTER FROM GMC, WE HAVE BEEN INTO THE DEALERSHIP TO GET IT RESOLVED, BUT THEY WILL NOT DO IT BECAUSE OUR MILES ARE OVER. I HAVE TOLD THEM THAT THEY KNOW ITS AN ISSUE AND THAT IT IS INTERMITTENT AND WHEN PEOPLE TAKE IT INTO THE SHOP TO GET IT DIAGNOSE, ITS A HIT AND MISS. I HAVE NOW SEEN OVER A DOZEN OTHER GMC'S ON THE ROAD WITH THE SAME ISSUE. LAST WEEK, WHILE TRAVELING WITH KIDS TO A SOCCER TOURNAMENT, BOTH WEREN'T WORKING AT NIGHT AND WE WERE PULLED OVER. I FORTUNATELY HAD THE LETTER IN THE CAR AND SHOWED IT TO HIM. HE GAVE ME A WARNING AND ADVISED THAT IT IS VERY DIFFICULT FOR CARS TO SEE AT NIGHT WHEN THERE ARE NO TAILGATES ON AND THAT GMC HAD BETTER GET THIS RESOLVED. I HAVE MADE TWO REQUESTS WITH GMC AND THEY HAVE DENIED THE REQUEST. I EVEN TOLD THEM THAT I WOULD COST SHARE IF WE MEET IN THE MIDDLE AND THEY WOULD NOT. THEY KNOW THIS IS AN ISSUE, YET THEY AREN'T WILLING TO EXTEND THE WARRANTY OR MAKE IT A RECALL. THIS IS VERY DANGEROUS AND COULD CAUSE A LOT OF ACCIDENTS WITH GMC MODELS NATIONWIDE. I HOPE THAT THIS IS BROUGHT TO SOMEONE'S ATTENTION AND THAT GMC IS ENCOURAGED TO GET THIS RESOLVED WITH 2015 YUKON XL SUVS AND THAT WE AND MANY OTHERS ARE ABLE TO GET THEIR TAILGATES REPLACED.

2015 GMC YUKON. CONSUMER WRITES IN REGARDS TO YUKON TAIL LIGHTS SAFETY RECALL. *LD *JS

NHTSA ODI 11310253

THE RIGHT REAR BRAKE LIGHT LED STRIP NO LONGER WORKS. I HAVE NOTICED THAT THIS IS AN ON-GOING ISSUE WITH OTHER CONSUMERS. THE DEALER WANTS $650-$750 TO REPLACE. MOST OF THE TIME, IT IS A WIRING ISSUE THAT NEEDS TO BE REPAIRED. UNFORTUNATELY, THE PLASTICS ARE GLUED TOGETHER PREVENTING ACCESS TO MAKE THE REPAIR.

NHTSA ODI 11311589

THE REAR PASSENGER BRAKE LIGHTS JUST RANDOMLY STOPPED WORKING. NOT A BULB ISSUE AS IT IS AN LED PANEL OF LIGHTS. THE BACK UP BULB STILL WORKS, BUT THE BRAKE LIGHTS DON'T. DEALER SAYS IT HAPPENS A LOT TO THESE CARS, AND HAVE TO BUY A WHOLE NEW UNIT. THIS IS A SAFETY ISSUE - BREAK LIGHTS FAILING DUE TO POOR WIRING. AGAIN NOT A REPLACEABLE BULB ISSUE, IT IS DUE TO A WIRING ISSUE WITHIN THE LIGHTING UNIT ITSELF

NHTSA ODI 11310629

REAR TAIL LAMPS ONLY WORK EVERY NOW AND THEN. HAPPENS WHILE MOVING AND STATIONARY. THE REAR TAIL LAMPS ARE CHEAPLY MADE INTERNALLY THAT THE CIRCUIT BOARD FOR THE LED LIGHTS EASILY BREAKS WITH REGULAR DRIVING. ITS AND OBVIOUSLY KNOW ISSUE FOR GMC BECAUSE THERE ARE BUSINESSES ONLINE THAT THERE SOLE INCOME IS TO REPAIR THESE TAIL LIGHTS ON 2015 TO CURRENT YUKON/ YUKON XL MODELS. TAKEN MY 2015 YUKON IN BEFORE WARRANTY WAS OUT AND GMC DEALER DOESN'T WANT TO WARRANTY AND DOESN'T WANT TO REPAIR. TELLS OWNERS THEY'LL HAVE TO BUY A NEW TAIL LAMP AT $800 A PIECE. TOTAL RIP OFF .
