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

THE TAIL LIGHTS STOP WORKING OR THEY FLICKER LIKE THERE'S A LOOSE CONNECTION OR SOMETHING NOT MAKING CONTACT I E SEEN OTHER COMPLAINTS ABOUT THE SAME THING AND GM NOW HAS A NEW IMPROVED TAIL LIGHT BUT THE OLD ONES ALL FAIL ALL STOP WORKING . ON THE BRAKING SYSTEM IT DOESN'T BRAKE WHEN GOING A LOW SPEED WITHOUT GIVING IT GAS I HAVE TO PUMP N PUSH THE BRAKES ALL THE WAY DOWN OR GIVE IT A LIL GAS TO BE ABLE TO STOP OR BRAKE THE LIGHTS FLICKER OR STOP WORKING WHILE DRIVING STOP ALL THE TIME THE DEALER WANTS 1500-2000 TO REPLACE EM THE LIGHTS.. THEY ARE DEFECTIVE AND SHOULD BE RECALLED THEIR BAD WORKMANSHIP SHOULDN'T BE MINE OUR ANYBODY ELSE THAT HAS THIS VEHICLE BURDEN THIS IS NOT A CHEAP VEHICLE I PAID OVER $50,000 USED FOR ABOUT A YEAR.. I NEED YOUR HELP. THE BRAKES NEED TO BE FIXED ALSO BECAUSE AT LOW SPEEDS WITH NO GAS ON THE PEDAL I CAN ROLL INTO SOMETHING HIT SOMETHING OR SOMEONE. *TR

BOTH LED BRAKE LIGHTS STOPPED WORKING. THEY WERE BOTH REPLACED BY THE DEALERSHIP. NOW APPROXIMATELY 7 MONTHS LATER THE PASSENGER BRAKE LIGHT HAS STOPPED WORKING AGAIN. THIS IS A VERY EXPENSIVE PART, WHICH COST $700.00 EACH SIDE, AND HAS FAILED TWICE IN YEAR. FROM A SIMPLE SEARCH ON THE INTERNET THIS SEEMS TO BE A VERY COMMON PROBLEM FOR GMC YUKON'S AND DENALI'S BUT THERE IS NOT A RECALL FOR THIS FAILURE. THE PROBLEM SEEMS TO BE A FAULTY DESIGN. THE SOLDER CONNECTION PREMATURELY BREAKS AND CAUSES THE LED BRAKE LIGHTS TO NOT WORK. *TR

WE PURCHASED THIS VEHICLE IN FEBRUARY 2019. LESS THAN A YEAR LATER OUR RIGHT TAIL LIGHT STARTED GOING OUT RANDOMLY. THEN IT COMPLETELY WOULD NOT WORK. WE PAY FOR AN EXTENDED WARRANTY, BUT IT DIDN'T COVER IT. THEN SHORTLY AFTER THE LEFT TAIL LIGHT DID THE SAME THING. WE CURRENTLY HAVE 84K MILES ON OUR VEHICLE. DUE TO NEGLIGENCE, AND A DISHONEST COMPANY (GMC), THIS MILITARY FAMILY IS DOWN TO 1 VEHICLE AS WE CANNOT AFFORD THE ALMOST $2K IT WILL COST TO FIX THE TAIL LIGHTS. THIS IS NOT DUE TO ANYTHING WE DID, IT HAS EVERYTHING TO DO WITH FAULT BRAKE LIGHTS THAT GMC WILL NOT FIX PAST 72K MILES WHICH IS DISGUSTING AND A SLAP IN THE FACE TO PEOPLE WHO GIVE THEM THEIR HARD EARNED MONEY. I HAVE DONE EXTENSIVE RESEARCH AND THIS IS A VERY COMMON PROBLEM IN THESE VEHICLES. THERE ARE DOZENS OF BLOGS, POSTS, WEBSITES, ETC OF CUSTOMERS COMPLAINING OF THIS ISSUE AND GMC NOT HELPING PAST 72K MILES WHICH IS A HORRIBLE EXPLANATION AND IS NOT HELPFUL TO MOST OF US. WE HAVE ALREADY HAD TO PAY OUT OF POCKET FOR THINGS THAT HAVE BROKEN (NORMAL WEAR AND TEAR WHICH IS UNDERSTANDABLE) THAT WASN'T COVERED UNDER OUR PLATINUM EXTENDED WARRANTY. HOWEVER, GMC NEEDS TO DO THE RIGHT THING ESPECIALLY FOR OUR MEN AND WOMEN IN UNIFORM, AND FIX WHAT THEIR COMPANY HAS DEEMED AS FAULTY PAST 72K MILES!!! *TR

THE BRAKE LIGHT IS NOT WORKING. ALL OTHER FUNCTIONS IN THE ASSEMBLY ARE FINE. REVERSE AND TURN SIGNAL, NO BRAKE INDICATION. IT DOES NOT ACTIVATE A WARNING ON THE DASH FOR THE BRAKE LIGHT FAILURE. THIS HAPPENS 24/7... THIS SHOULD NOT OCCUR WITH AN ITEM PRICED AT OVER $700.00 TO REPLACE. *TR

I PURCHASED BY VEHICLE IN THE SUMMER OF 2015. IT HAS BEEN IN THE SHOP NUMEROUS TIMES FOR VARIOUS ISSUES, MOSTLY ELECTRICAL INVOLVING THE COMPUTER AND SOFTWARE, OR ISSUES INVOLVING MY TIRES OR STEERING WHEN TURNING THE STEERING WHEEL.. MY "DRIVER ASSIST" HAS MALFUNCTIONED MANY TIMES AND I HAVE TAKEN IT TO THE SHOP TO HAVE IT REPAIRED ON 3 SEPARATE OCCASIONS. LAST SUMMER MY FRONT AND REAR LIGHTS STARTED FLICKERING AND STOPPED WORKING. I SPENT $800 FOR THE BACK PASSENGER BRAKE LIGHT AND ALMOST $1000 FOR THE FRONT DRIVER HEAD LIGHT ASSEMBLY. I ALSO HAD TO GET A NEW BATTERY FOR THIS VEHICLE. MY 2015 GMC YUKON XL IS NOW MALFUNCTIONING AGAIN AND THIS TIME, I AM TOLD THAT THE SEAT MOTOR (THAT ALERTS YOU WHEN YOU ARE NEAR AN OBSTACLE HAS BURNED OUT.) ABOUT 4 DAYS AGO, I BECAME AWARE OF TICKING NOISE WHILE MY CAR HAS BEEN IDLE. I IMMEDIATELY SCHEDULED A MAINTENANCE APPOINTMENT. TODAY, I AM ALSO INFORMED THAT MY "LIFTERS" ARE BAD ON THE VEHICLE AND MY ENGINE IS GOING BAD. I AM TOLD THE AIR CONDITIONING CONDENSER HAS BURNED OUT, I AM TOLD THE MOTOR UNDER MY SEAT IS BURNED OUT. I HAVE PERFORMED ROUTINE MAINTENANCE, I GET OIL CHANGES REGULARLY AND USE HIGH QUALITY SYNTHETIC OILS. I TAKE MY CAR TO THE SHOP AT LEAST 2X PER YEAR FOR PROBLEMS AND SOME MAJOR REPAIR IS ALWAYS REQUIRED. THIS IS A CAR THAT I AM GOING INTO THE 5TH YEAR OF OWNERSHIP THIS SUMMER. ORIGINALLY. I WAS TOLD THAT THERE WAS A RECALL FOR BRAKES, NOW I AM TOLD THERE IS NOT, BUT I HAVE TAKEN MY CAR IN FOR VARIOUS RECALLS AT LEAST 3X. THIS IS AN UNSAFE, DEFECTIVE VEHICLE. EVERY SYSTEM FAILS. I AM NOW IN SEARCH OF A NEW VEHICLE. I HAVE DRIVEN OTHER GM VEHICLES (GRAND AM, HUMMER) AND NONE HAVE REQUIRED SO MUCH REPAIR COSTS. TODAY I AM TOLD THAT IT WILL COST $6800 TO REPAIR MY VEHICLE TO MAKE IT SAFE. MY REPAIR RECORDS WILL SHOW THE REPAIRS AND SERVICE CHARGES I HAVE PAID SINCE PURCHASE. THIS IS A LEMON. *TR

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

WAS DRIVING DOWN THE ROAD AND SUDDENLY THE CHECK ENGINE LIGHT STARTED FLASHING AND THE ESP LIGHT CAME ON. I WAS VERY CLOSE TO HOME SO I DROVE BACK HOME AND AS I STOPPED THE CAR IT STARTED SHAKING AND I TURNED IT OFF. BROUGHT IT TO THE MECHANIC AND HE SAID THE FUEL INJECTORS NEED TO BE REPLACED. I HAVE BEEN WITHOUT MY CAR FOR 11 DAYS NOW AS THIS IS SUCH A COMMON PROBLEM THAT ALL THE PARTS ARE ON BACK ORDER. THIS IS VERY DANGEROUS AND NEEDS TO BE RECALLED ESPECIALLY AS IT IS SUCH A COMMON PROBLEM. FOR SUCH AN EXPENSIVE CAR THESE KINDS OF THINGS SHOULD NOT BE HAPPENING. HOPING FOR A RECALL SOON SO THAT I CAN RECEIVE MY MONEY BACK. *TR

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!

WHILE DRIVING APPROXIMATELY 60 MPH ON A DESERTED FLAT STRETCH OF ROAD SURROUNDED BY FARMLAND, MY SUNROOF SUDDENLY EXPLODED. THE SCREEN WAS OPEN TO PROVIDE LIGHT BUT THE GLASS WAS SHUT. NO OTHER CARS WERE NEARBY NOR WERE ANY HILLS WHERE A ROCK COULD FLY FROM. IT WAS JUST SUDDEN. IT SOUNDED LIKE A LOUD EXPLOSION AND SUDDENLY GLASS WAS FLYING ALL OVER THE CAR. FORTUNATELY, I DIDN'T CRASH THE CAR. MYSELF AND MY SON WHO WAS IN THE PASSENGER SEAT, WE WERE BOTH COVERED IN GLASS. *TR

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.

HAVE HAD MY VEHICLE AT THE SHOP FOR TRANSMISSION ISSUES SEVERAL TIMES. TWO OF THE TIMES, ISSUES WERE DUPLICATED AND PARTS REPLACED, BUT SAME ISSUES CONTINUE AS SOON AS I GET IT BACK. MY COMPLAINT WHEN I TAKE IT IN IS ALWAYS THE SAME. NORMALLY WHEN I ACCELERATE FROM A DEAD STOP FORWARD OR REVERSE, THE TRANSMISSION MAKES A THUMPING NOISE. IT HAS STEADILY GOTTEN WORSE. A LOT OF TIMES NOW IF I TAKE MY FOOT OFF GAS FOR A SECOND, AT FASTER SPEEDS, AND THEN PUT FOOT RIGHT BACK ON GAS, IT MAKES THE SAME THUMPING NOISE AND SOMETIMES A GRINDING NOISE LIKE IT'S STUCK BETWEEN GEARS. THIS LAST TIME I TOOK IT TO THE DEALER, WAS TOLD THERE WAS NOTHING THEY COULD DO AND WOULD MOST LIKELY GET WORSE AS VEHICLE GETS OLDER.
