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

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.

NHTSA ODI 11119328

TAKATA RECALL WAS PULLED OVER BECAUSE MY PASSENGER TAIL LIGHT WAS NOT WORKING. TAIL LIGHT WAS WORKING THE NEXT DAY, AND THE FOLLOWING DAY IT HAD GONE OUT AGAIN. LIGHT WOULD COME BACK ON WHEN YOU HIT IT BY HAND.

NHTSA ODI 11118799

PASSENGER SIDE LED BRAKE LIGHT DOES NOT WORK WHEN BRAKING. ASSEMBLY HAS BEEN REMOVED AND SWITCHED WITH DRIVER SIDE TO VERIFY THAT IT IS NOT THE WIRING HARNESS OR ANY ELECTRICAL BETWEEN THE BRAKES AND THE LED BRAKE LIGHTS.

NHTSA ODI 11118225

LED BRAKE LIGHTS WENT OUT. WHEN I DID A SEARCH ON THIS PROBLEM, DISCOVERED THAT MANY OTHERS HAVING THE SAME PROBLEM WITH THEIR YUKONS. DEALERS CHARGING ASTRONOMICAL PRICES TO FIX. LEDS ARE SUPPOSED TO LAST LONGER THAN REGULAR BULBS. THESE LIGHT ASSEMBLIES HAVE A WELL KNOWN WEAK SPOT THAT CAUSES THEM TO GO OUT. GMC HAS COME UP WITH AN UPDATED ASSEMBLY. THEY SHOULD ISSUE A RECALL AND REPLACE THE ORIGINAL WEAK ASSEMBLIES WITH THE NEW ONES.

DRIVERS SIDE BRAKE LIGHT SOMETIMES WORKS, SOMETIMES DOESN'T.

NHTSA ODI 11118356

RIGHT TAIL LIGHT (ONLY RED LIGHT) DOESN'T WORK. REVERSE LIGHT WORKS AND SIGNAL LIGHT WORKS ALL THE TIME BUT RED PART DOESN'T. IT WORKS AND THEN IT DOESN'T. IT DOES IT RANDOMLY.

BRAKE PEDAL SUDDENLY GOT ROCK HARD WHEN I WAS TRYING TO SLOW DOWN, OUR TRUCK JUST KEPT GOING FORWARD, I WAS HELPLESS IN THAT SITUATION AND REALLY THOUGHT THAT ACCIDENT IS UNAVOIDABLE BECAUSE I WAS GETTING CLOSER AND CLOSER TO ANOTHER VEHICLE, AFTER PRESSING BRAKE PEDAL MANY MORE TIMES I WAS ABLE TO STOP OUR YUKON LITERALLY ONE INCH FROM A CAR IN FRONT OF ME

NHTSA ODI 11115892

AT LESS THAN 3 YEARS OLD BOTH TAILLIGHTS HAVE QUIT. THEY ARE A SEALED ASSEMBLY SO THE WHOLE SIDE NEEDS REPLACED. WE WERE QUOTED $750 EACH. OUR THREE YEAR OLD YUKON HAS NO TAILLIGHTS AND WILL TAKE $1500 TO REPLACE. I'M DISAPPOINTED IN GM TO SAY THE LEAST.

TL* THE CONTACT OWNS A 2015 GMC YUKON. WHILE DRIVING 65 MPH, THE BRAKE PEDAL WAS DEPRESSED, BUT THE BRAKE LIGHTS, TAIL LIGHTS, AND THE INTERIOR REAR BRAKE LIGHT FLICKERED. THE VEHICLE WAS TAKEN TO DELANO CHEVROLET BUICK GMC (600 1ST AVE, DELANO, CA 93215, 661-735-4974) TO BE DIAGNOSED AND REPAIRED. THE DIAGNOSIS RESULTS WERE UNAVAILABLE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 92,000.

PASSENGER SIDE TAILLIGHT IS NOT WORKING CORRECTLY. SIGNAL WORKS, BUT THE BRAKE LIGHT AND RUNNING LIGHT DOES NOT WORK. I GOT THIS VEHICLE IN APRIL 2014, TAILLIGHT STARTED GOING OUT EXACTLY 2 YEARS AFTER PURCHASE. TOOK VEHICLE TO DEALERSHIP AND THEY SAID IT WOULD BE ABOUT $650 TO REPLACE THE WHOLE TAILLIGHT AND THAT IT WAS NOT REPAIRABLE. THE TAILLIGHT IS STILL OUT AND I REFUSE TO REPLACE IT SINCE I BELIEVE THIS IS A DEFECT. I HAVE HEARD MANY OTHER SIMILAR STORIES OF OTHER YUKONS WITH THIS SAME PROBLEM. WHEN IN COLD WEATHER (UNDER 60 DEGREES F) THE LIGHT USED TO FLICKER BUT NOT STAY ON. IT HAS BEEN HOT MOST OF THIS YEAR SO I DO NOT KNOW IF THIS IS STILL TRUE.

NHTSA ODI 11115144

I WAS TOLD MY A COLLEGUE THAT MY DRIVERS SIDE BRAKE LIGHT WAS OUT. I TOOK IT INTO THE LOCAL MECHANIC AND IT WAS NOT OUT. A FEW MONTHS GO BY AND I AM TOLD AGAIN, THAT MY DRIVERS SIDE TAIL LIGHT IS OUT. I TAKE IT TO A DIFFERENT SHOP AND IT IS WORKING CORRECTLY. THE VERY NEXT DAY A TRUCK TELLS ME AT A STOP LIGHT THAT I HAVE NO BRAKE LIGHTS. I WAS PULLED OVER BY A POLICE OFFICER FOR NOT HAVING PROPERLY WORKING BREAK LIGHTS. HE LET'S ME GO WITH A FRIENDLY NOTICE, BUT AS SOON AS I STARTED MY VEHICLE TO DRIVE AWAY HE IMMEDIATELY PULLS ME BACK OVER TO TELL ME THAT HE WAS MISTAKEN THAT ONLY MY DRIERS SIDE BRAKE LIGHT WAS OUT. THIS HAS HAPPENED INTERMITTENTLY OVER THE LAST THREE TO FOUR MONTHS.

NHTSA ODI 11115220

MY RIGHT SIDE BRAKE ASSEMBLY SEEMS TO ONLY WORK WHEN IT WANTS TOO. WORKS ON COLD MORNINGS, BUT AS THE DAY GETS WARMER THE LIGHT ASSEMBLY DOESN'T WORK ANYMORE. NO LIGHTS, OR BRAKE LIGHTS.

NHTSA ODI 11114940

BRAKE LIGHTS ONLY WORK INTERMITTENTLY. THIS POSES A SAFETY HAZARD WHILE DRIVING AND COULD CAUSE A WRECK. REPLACEMENT IS $800 PER LIGHT, VERY COST PROHIBITIVE.

NHTSA ODI 11114467

BRAKE LIGHTS ARE FAILING INTERMITTENTLY. DEALER HAS RECOMMENDED REPLACING BOTH TAIL LIGHT HOUSING ASSEMBLIES AT A SIGNIFICANT COST OF $750 EACH. DEALER HAS ALSO STATED THIS IS A "COMMON PROBLEM" OF THE 2015 GMC VEHICLES WITH AN LED BRAKE LIGHT DESIGN; NO EASY OR AFFORDABLE SOLUTION OUT THERE.

NHTSA ODI 11114505

COMPONENT AFFECTED: STABILITRAC MODULE CAUSE: A POWER SHORT IN THE ELECTRICAL WIRING HARNESS INSIDE THE STEERING WHEEL COLUMN CAUSED THE STABILITRAC (STABILITY CONTROL) MODULE TO MALFUNCTION. UNSAFE CONDITION: THE STEERING WHEEL WOULD TURN A FULL 180 DEGREES ON ITS OWN AT IDLE/LOW SPEED. AT HIGHER SPEEDS, THE CAR WOULD PULL TO THE LEFT OR RIGHT. THE "SERVICE STABILITRAC" LIGHT WOULD ACTIVATE ON THE DASH AND MESSAGE DISPLAYED "STABILITRAC DISABLED". REMEDY: THE STEERING WHEEL WIRING HARNESS WAS REPAIRED AND THE STABILITRAC MODULE WAS REPLACED BY MY GMC DEALERSHIP IN THE SUMMER OF 2017, THE ISSUE HAS NOT OCCURRED SINCE.

NHTSA ODI 11114512

THE BRAKE LIGHTS ON 2015 AND NEWER GMC YUKON, YUKON XL, DENALI, DENALI XL VEHICLES FAIL DUE TO POOR QUALITY CIRCUIT METAL/DESIGN OF BOARD ALLOWING TOO NARROW A CONNECTION FOR METAL USED. THE RESULT IS A CRACK IN THE CIRCUITS METAL WHICH, DEPENDING ON CONDITIONS, BREAKS THE CIRCUIT AND THE TAIL LIGHTS FAIL TO WORK. SPECIFICALLY BRAKE LIGHTS FAIL FIRST PUTTING THE DRIVER OF THE VEHICLE IN AN SERIOUS SAFETY SITUATION WITH NO INDICATION THAT THE FAILURE HAS HAPPENED. IN ADDITION, THE SAFETY OF DRIVERS BEHIND A GM VEHICLE EXHIBITING THIS PROBLEM ARE AT SERIOUS RISK AS THEY MAY NOT REALIZE THE VEHICLE IS COMING TO A STOP. GMC IS REFUSING TO COVER THE ISSUE AND REQUIRES $800 PER LIGHT AND OPENLY ACKNOWLEDGES THAT THE NEW LIGHT CAN DO THE SAME THING AT ANY GIVEN TIME. I DON'T NORMALLY GO SO FAR WITH AN ISSUE, BUT THIS SEEMS PARTICULARLY DANGEROUS AND WARRANTS A RECALL. WITH THE LACK OF INDICATION OTHER THAN COURTEOUS DRIVERS TELLING YOU THE LIGHTS ARE OUT OR POLICE PULLING YOU OVER TO TELL YOU, THE ISSUES OFTEN START WITHIN WARRANTY PERIOD BUT NO WAY TO KNOW. NUMEROUS REPORTS OF TAIL LIGHT FAILURES WITH NEW VEHICLES INDICATE THAT THE ISSUE IS NOT RELATED TO AGE. AS WITH MY LIGHTS, NO PHYSICAL DAMAGE TO THE LIGHT AT ALL ELIMINATES SOME KIND OF IMPACT OUTSIDE OF NORMAL ROAD BUMPS. HOPEFULLY ACTION CAN BE TAKEN.

NHTSA ODI 11114534

BOTH LED BRAKE LIGHTS HAVE FAILED. IF YOU TAP THEM THEY WOK FOR A MINUTE BUT WHEN DRIVING THEY GO OUT AGAIN. THE SEAT VIBRATES TO ALERT YOU OF OBSTACLES BUT THE MOTOR IN THE SEAT ONLY WORK PERIODICALLY. THE REAR WINDOW WIPER HAS FAILED. THE YUKON HAS BEEN DRIVEN 3 YEARS AND 50K MI AND NOW NEEDS THOUSANDS OF DOLLARS IN REPAIRS BECAUSE OF THE DEFECTIVE PARTS USED.

NHTSA ODI 11114352

I WAS DRIVING AND WITH WARNING SUV STARTED ACCELERATING AND I BRAKES WOOD NOT WORK I WAS NOT ABLE TO STOP INTILL I PRESS HARD ON THE PEDAL

NHTSA ODI 11114244

THE RIGHT & LEFT REAR BRAKE LIGHTS AND RUNNING LIGHTS INTERMEDATLY FAIL. I HAVE HAD MY RIGHT ONE FAIL, MY LEFT ONE FAIL AND ON ONE OCCASION BOTH FAILED (RIGHT, LEFT, BRAKE & RUNNING LIGHTS AT NIGHT TIME. I HAD PEOPLE FLAGGING ME DOWN AT INTERSECTIONS AND HAD FRIENDS TEXT ME WHILE THEY OBSERVED ME DRIVE AWAY. THE LIGHTS WOULD SOMEHOW BEGIN TO FUNCTION PROPERLY BUT IT IS UNKNOWN HOW LONG THEY WOULD REMAIN NON FUNCTIONING. THIS IS AN ENORMOUS SAFETY CONCERN! IT IS UNBELIEVABLE THAT GM HAS NOT RECALLED THE POORLY MANUFACTURED LED LIGHTS ON THEIR VEHICLES. THE FACT THAT THEY FUNCTION PROPERLY ONE DAY AND THEN DON'T FUNCTION THE NEXT IS UNACCEPTABLE. MY INITIAL QUOTE FROM GM TO HAVE THE LIGHT REPLACED WAS $1,600 FOR BOTH LIGHTS. RIDUCLOUS COST FOR A FOUR YEAR OLD $60K + VEHICLE. IT SHOULD BE NOTED THAT THE TOP /THIRD BRAKE LIGHT SEEMED TO FUNCTION AT ALL TIMES OR WAS NEVER REPORTED TO ME AS NOT FUNCTIONING. I DON'T HAVE PHOTOS OF THE INOPERABLE REAR BRAKE LIGHTS. BOTH

MY VEHICLE IS CURRENTLY A LITTLE OVER 3 YEARS OLD AND I HAVE OWNED THE VEHICLE FOR THE LAST 2.5 YEARS. I AM HIGHLY UPSET THAT THE VEHICLE IS IN GREAT CONDITION, HOWEVER THE FRONT DRIVER SIDE LED STRIP IN THE HEAD LIGHT IS OUT. I PURCHASED AN EXTENDED WARRANTY FOR ALMOST $2000 WHEN I BOUGHT THE VEHICLE WHICH THEY WILL NOT COVER. I ALSO HAVE THE BACK PASSENGER TAIL LIGHT OUT AND I AM TOLD THAT THE WHOLE PANEL NEEDS REPLACING. A TOTAL FOR THE LED STRIP AND BACK PANEL WILL COST CLOSE TO $1900. WHY IN THE WORLD IS IT THAT AND LED LIGHT IS SUPPOSED TO LAST 5X LONGER THAN A REGULAR LIGHT, BUT IT JUST GOES OUT? THAT MAKES NO SENSE. IF THE VEHICLE WAS 10 YEARS OLD, THAT IS ONE THING, BUT IT BEING STILL ON THE NEW END, MAKES NO SENSE. ALSO, HOW DOES THE WHOLE BACK LIGHT PANEL JUST GO OUT? AND WHY DO DEALERSHIPS ACT LIKE " OH WELL, THERE IS NOTHING WE CAN DO!" GMC MUST BE LOWERING THEIR STANDARDS. HAD I KNOWN THIS VEHICLE WOULD HAVE THESE PROBLEMS AND NO ONE SEEMS TO WANT TO HELP, THEN I WOULD HAVE NEVER BOUGHT IT. SOMETHING NEEDS TO BE DONE, ESPECIALLY SINCE I HAVE SPEND THE LAST 30 MINUTES READING A FORUM OF A LARGE AMOUNT OF OTHERS HAVING HAD THE SAME ISSUE.

NHTSA ODI 11114185

LED BRAKE LIGHTS HAVE GONE OUT AND THERE IS NOT A REASONABLE REPAIR.

NHTSA ODI 11113808

THE SUBURBAN IS NOT FULLY 3 YEARS OLD AND HAVING ISSUES WITH THE TAIL LIGHTS. IT IS 1700.00 TO REPAIR TAIL LIGHTS. THAT IS CRAZY. THE LIGHTS GO ON AND OFF. DAYS IT WORKS DAYS IT DOESN'T. I HAVE HAD 2 WARNINGS TO GET THEM FIXED. FIRST IT WAS JUST THE RIGHT ONE AND THE OFFICER NOTICED THAT THE LEFT KEEP GOING ON AND OFF.
