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

TL* THE CONTACT OWNS A 2015 GMC YUKON DENALI. WHILE REVERSING THE VEHICLE, THE CONTACT WAS INFORMED THAT THE BRAKE LIGHTS WERE NOT ILLUMINATING. HOWEVER, WHEN THE VEHICLE WAS IN DRIVE, THE BRAKE LIGHTS ILLUMINATED. ALSO, WHEN THE CONTACT DEPRESSED THE BRAKE PEDAL TO SLOW OR STOP THE VEHICLE, THE BRAKE LIGHTS DID NOT ILLUMINATE. THE CONTACT CALLED COULTER BUICK GMC PHOENIX (1202 E CAMELBACK RD, PHOENIX, AZ 85014, (602) 396-5994) AND WAS INFORMED THAT THERE WERE NO RECALLS. THE DEALER REFERRED THE CONTACT TO THE MANUFACTURER. THE MANUFACTURER WAS NOT CONTACTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 64,000.

OVER THE LIFE OF OWING THIS NEW CAR, FROM MARCH 2016 TO JULY 2019, THE REAR PASSENGER AND DRIVER SIDE TAIL LIGHT ASSEMBLY HAVE EACH FAILED ONCE AND WERE REPLACED BY MY OWN EXPENSE. AGAIN FOR A THIRD TIME TOTAL, THIS MONTH THE PASSENGER SIDE TAILLIGHT ASSEMBLY REPEATED ITS FAILURE TO HAVE THE BREAK LIGHT TO FUNCTION. I FEEL THIS AMOUNT OF PART FAILURE INSIDE 3 YEARS IS TOO EXTREME AND IS DUE TO POOR DESIGN BY THE MANUFACTURER. THESE FAILED PARTS HAPPENED AT 16,000, 30,000 AND 50,000 MILES OF VEHICLE USE. NONE OF THE TAILLIGHT PARTS WERE EVER PHYSICALLY DAMAGED BEFORE. THE COST OF THE PART ALONE IS $795.00. THAT IS EVEN MORE REDICULOUS CONSIDERING A HOME LED BULB LASTS LONGER AND COSTS MUCH LESS.

TAIL LIGHT KEEP GOING OFF, DEALER WONT FIX IT UNDER WARRANTY, THEY $700 WHEN ITS A MANUFACTURE ISSUE, SOMETHING WRONG THAT KEEP BURNING THE LED LIGHTS.

NHTSA ODI 11244391

LEFT TAIL LIGHT IS INTERMITTENTLY FAULTY. BRAKE LIGHT ONLY WORKS INTERMITTENTLY.

NHTSA ODI 11244111

REAR LED TAILLIGHTS WORK INTERMITTENTLY. FOUND SEVERAL FORUMS WHERE THIS HAPPENS TO A LOT OF PEOPLE. IF YOU TAP THE TAILLIGHT IT SOMETIMES BEGINS WORKING AGAIN. TRUCK ONLY HAS 60K MILES AND GM WANTS OVER $1200 TO FIX (REPLACE BOTH TAILLIGHTS). EVIDENTLY THERE'S A CIRCUIT BOARD THAT GOES BAD INSIDE. I HAD THIS AT GM TO BE FIXED BUT BECAUSE TAILLIGHTS WERE WORKING AT THE TIME, THEY FOUND NO PROBLEM.

NHTSA ODI 11243894

REAR BRAKE LIGHT ASSEMBLY FAILING TO LIGHT WHEN BRAKES APPLIED AND THERE IS NOT A NOTIFICATION TO THE DRIVER. THIS IS A MANUFACTURE FLAW WITH THE LED LIGHT CIRCUIT INSIDE THE ASSEMBLY. THERE IS NOT A LIGHT OUT NOTIFICATION SO THE DRIVER IS NOT AWARE THE BRAKE LIGHT HAS FAILED. THIS IS A SAFETY ISSUE AND IS AN WELL KNOWN ISSUE ON THE 2015-2019 YUKON. THIS IS OCCURRING OFTEN AND GMC IS HAVING PROBLEMS WITH SUPPLYING REPLACEMENTS BECAUSE THE DEMAND IS SO HIGH FROM THE FAILURE. GMC HAS ALSO RAISED THE PRICE OF THE BRAKE LIGHT BY 30% FROM $425 TO $675 NOT INCLUDING LABOR. I CALLED THE DEALER AND THEY INFORMED IT WAS A HIGH FAILING ITEM AND WAS ON BACKORDER AND NOT SURE WHEN THEY WOULD GET ONE. DRIVING THE VEHICLE WITHOUT PROPER BRAKE LIGHTS IS A SAFETY CONCERN AND NOT LEGAL SO LEFT WITH LITTLE OPTION BUT TO STOP DRIVING THE YUKON.

NHTSA ODI 11242951

REAR TAIL/BRAKE LIGHT FAILED AFTER FUNCTIONING INTERMITTENTLY FOR A MONTH. GMC DEALER REPLACED THE ENTIRE ASSEMBLY WITH A NEW GM PART AT A COST OF OVER $800. GMC DEALER EXPLAINED THAT DESPITE CHRONIC FAILURES OF THIS PARTICULAR PART, GM REFUSES TO RECALL. FAILURE APPEARS TO RESULT FROM A FAULTY CIRCUIT BOARD THAT CANNOT BE REPLACED OR REPAIRED EASILY. INTERMITTENT NATURE OF THE FAILURE IS AN UNSAFE CONDITION, ESPECIALLY AT NIGHT OR IN FOUL WEATHER.

NHTSA ODI 11242997

PURCHASED VEHICLE (USED) FROM DEALER LESS THAN 2 YEARS AGO. DRIVER TAILLIGHT WENT OUT. NOT COVERED UNDER WARRANTY BUT IS A SAFETY ISSUE THAT ACCORDING TO SEVERAL FORUMS IN A KNOWN PROBLEM. THE TAILLIGHT IS ARCHITECTED, ENGINEERED, AND BUILT IN SUCH A WAY AS TO BE VERY EXPENSIVE TO REPLACE, BREAK OFTEN, AND DISCOURAGE DIY OR NON-DEALER REPAIRS. THE VEHICLE WAS STATIONARY WHEN THE PROBLEM WAS NOTICED.

NHTSA ODI 11242621

SOMEONE WHO WAS DRIVING BEHIND ME TOLD ME MY DRIVER'S SIDE BRAKE LIGHT WAS OUT. I CHECKED IT WITH THE HELP OF SOMEONE ELSE A COUPLE TIMES AFTERWARDS AND IT WORKED. THEN A WEEK OR SO LATER A CO-WORKER TOLD ME THE SAME THING, THAT IT WAS OUT. I CHECKED IT AGAIN LATER AND IT WORKED, SO THE PROBLEM WAS INTERMITTENT. WHEN I TOOK IT TO THE DEALER, THE TAILLIGHT ASSEMBLY HAD TO BE REPLACED. I JUST PURCHASED THE VEHICLE 1/7/2019 AND BEFORE IT WAS OFFERED FOR SALE THE PASSENGER-SIDE TAIL LIGHT ASSEMBLY WAS ALSO REPLACED.

TL* THE CONTACT OWNS A 2015 GMC YUKON. THE CONTACT STATED THAT THE REAR DRIVER'S SIDE BRAKE LIGHT AND PASSENGER SIDE TAIL LIGHT WERE BURNED OUT. THE CONTACT STATED THAT THE BRAKE LIGHTS WOULD NOT ILLUMINATE. THE VEHICLE WAS TAKEN TO ED BOZARTH CHEVROLET (2001 S HAVANA ST, AURORA, CO 80014, (720) 746-2716) AND JOHN ELWAY CHEVROLET (5200 S BROADWAY, ENGLEWOOD, CO 80113, (720) 259-0391), BUT THE PARTS WERE NOT AVAILABLE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND PROVIDED A CASE NUMBER. THE FAILURE MILEAGE WAS 81,000.

WHILE SITTING STILL AT A DRIVE THROUGH, BRAKE PEDAL WENT TO FLOOR AS IF IT HAD NO PRESSURE. HAD NO BRAKES! NO MATTER HOW HARD I STOOD ON PEDAL THE CAR WOULD NOT COME TO COMPLETE STOP WHEN ROLLING. BLEW THROUGH STOP SIGNS AND LIGHTS BECAUSE EVEN AT 10 MPH COULD NOT STOP VEHICLE FROM ROLLING. HAD JUST GOT OFF INTERSTATE DOING 70 MPH. DOWN HILL GRADE WAS IMPOSSIBLE. FOUND OUT THAT THIS WAS A KNOWN ISSUE BY GM INVOLVING FAILURE OF VACUUM PUMP BOOSTER. MANY REPORTS, HOPEFULLY NOT MANY DEATHS CAUSED.

NHTSA ODI 11241066

REAR BRAKE AND TAIL LIGHTS DO NOT WORK INTERMITTENTLY. SOMETIMES THE LIGHTS WORK AND SOMETIMES THEY DON'T.

NHTSA ODI 11241163

TAIL LIGHT MALFUNCTION INTERMITTENTLY. THE TAIL LIGHTS AND BRAKE LIGHTS OCCASIONALLY WILL GO OUT AND COME BACK ON RANDOMLY. GMC KNOWS ABOUT THE ISSUE AND REPLACEMENTS COST ABOUT $750 PER UNIT WHICH EVEN THESE REPLACEMENTS HAVE BEEN KNOWN TO FAIL WITHIN A YEAR. THE FACT THAT THIS HAPPENS RANDOMLY AND SO INTERMITTENTLY THIS BECOMES A SAFETY ISSUE. I'VE HAD IT IN THE SHOP AND THEY SAID NOTHING WAS WRONG BECAUSE THEY WERE BOTH WORKING. I GET HOME AND THEY ARE NOT. IS THERE A WAY TO HAVE GMC REPLACE THESE VIA A SAFETY RECALL?

NHTSA ODI 11240737

2015 GMC YUKON DENALI REAR TAIL LIGHTS FAIL DUE TO DEFECTED PARTS. GMC WILL NOT REPLACE THE FAILED PARTS WHICH IS A KNOW SAFETY ISSUE. NUMEROUS COMPLAINTS ONLINE WITH THE GMC YUKON 2015-2019 MODELS.

NHTSA ODI 11240746

REAR TAIL/BRAKE/TURN LIGHTS RANDOMLY DON'T WORK. THIS ISSUE IS VERY COMMON AND COMPLAINED ABOUT REPEATEDLY ON THE INTERNET. I HAVE THIS ISSUE WITH MY LEFT TAIL LIGHT.

NHTSA ODI 11240173

APPROXIMATELY 6 MONTHS AFTER PURCHASING OUR 2015 GMC YUKON DENALI, HAVING ONLY DRIVEN UNDER NORMAL DRIVING CONDITIONS ON HIGHWAYS AND SURFACE STREETS FOR 15K MILES, THE PASSENGER SIDE TAIL / BRAKE LIGHT WENT OUT. IT WAS TAKEN IN FOR WARRANTY AND REPLACED BY THE DEALER. APPROX 6 MONTHS LATER THE DRIVER'S SIDE TAIL / BRAKE LIGHT DID THE SAME THING, AND WAS ALSO REPLACED BY THE DEALERSHIP. NOW APPROXIMATELY ONE YEAR LATER THE REAR PASSENGER LIGHT IS OUT AGAIN AND DEALER WANTS $600.00 TO REPLACE THE FAULTY BRAKE LIGHT LAMP, BUT CAN'T BECAUSE THEY'RE IN SUCH DEMAND BASED ON THE DEFECTIVE PART, THAT THEY ARE BACKORDERED. A QUICK INTERNET SEARCH INDICATES THOUSANDS OF PEOPLE HAVING THE SAME ISSUES.

NHTSA ODI 11235148

TAIL LIGHTS ONLY WORK INTERMITTENTLY

NHTSA ODI 11234367

REAR BRAKE LIGHTS STOP WORKING INTERMITTENTLY, SOMETIMES ONE DOESN'T WORK, SOMETIMES BOTH ARE OUT, SOMETIMES BOTH WORK. SEEMS WORSE IN THE HOT WEATHER. TAKEN IT IN MULTIPLE TIME, 1ST 2 TIMES COULDN'T DUPLICATE THE OUTAGE, 3RD TIME THEY SAID IT NEEDED BOTH TAILLIGHT ASSEMBLIES REPLACES FOR $1200. THEN THEY WORKED ALL WINTER, NOW NOT WORKING CONSISTENTLY.

NHTSA ODI 11234293

THE ELECTRIC POWER STEERING ASSIST MAY FAIL MOMENTARILY AND THEN SUDDENLY FUNCTION AGAIN. THIS CAN CAUSE DIFFICULTY STEERING THE VEHICLE, ESPECIALLY AT LOW SPEEDS, INCREASING RISK OF A CRASH. ALTHOUGH THERE IS A RECALL WHICH DESCRIBES EXACTLY WHAT IS HAPPENING RECALL 18V586000 THE DEALER SAYS THERE IS NO RECALL FOR MY VEHICLE AT LOW SPEEDS WHEN I BACK UP OR TURN I LOSE POWER MOMENTARILY THEN IT COMES BACK

NHTSA ODI 11233767

THE PASSENGER SIDE BRAKE/TAIL LIGHTS INTERMITTENTLY DO NOT WORK. THEY WORK ABOUT 60 PERCENT OF THE TIME AND THE OTHER 40 PERCENT THEY DO NOT. I HAVE READ MANY COMPLAINTS ONLINE ABOUT THIS ISSUE AND GM NEEDS TO STEP UP AND GET IT FIXED. IT IS A SAFETY ISSUE.

NHTSA ODI 11234002

TAIL LIGHT CIRCUIT (LED INTERNAL TO HOUSING) CRACKS, CAUSING RAIL/BRAKE LIGHT OUTAGE WITH NO WARNINGS ON THE DASH FOR THE DRIVER. THIS IS A MATERIAL DEFECT IN THE METAL STAMPING USED FOR THE LED POWER CIRCUIT. EXACERBATED BY HEAT AND VIBRATION.

NHTSA ODI 11234010

DRIVER SIDE REAR TAILLIGHT NOT WORKING, WAS TOLD IT WAS A BROKEN SOLID CIRCUIT BY THE DEALERSHIP. THEY WANT CLOSE TO $1000 TO REPLACE THE ENTIRE ASSEMBLY. THIS IS A VERY WELL KNOWN PROBLEM THAT GM IS NOT RECALLING!!!!

NHTSA ODI 11233646

BRAKE/TAIL LIGHTS HAVE GONE OUT. MY CAR ISN'T EVEN 5 YEARS OLD. THE REPAIR IS ASTRONOMICAL'AT LEAST $1500!!!

NHTSA ODI 11233328

MY VEHICLE HAS A CRACK IN THE COMBI-COOLER AS DESCRIBED IN NHSTA REFERENCE NUMBER: N162080780 AND GM SPECIAL COVERAGE ADJUSTMENT 17336. IN THE DOCUMENTATION FOR THE SPECIAL COVERAGE IT STATES THAT THE COVERAGE PERIOD IS 5 YEARS OF 60,000 MILES BASED ON THE DATE THE VEHICLE ENTERED SERVICE. THIS VEHICLE WAS A GM EXECUTIVE VEHICLE UNTIL PURCHASED WITH 15102 MILES VIA THE GM PEP PROGRAM. GM IS NOT INCLUDING MY VEHICLE EVEN THOUGH IT IS CLEARLY STATED IN THE COVERAGE SINCE THEIR SYSTEMS DO NOT ACCOUNT FOR A VEHICLE THAT ENTERS SERVICE WITH THIS MANY MILES. I BELIEVE THIS IS A VIOLATION OF THEIR AGREEMENT WITH NHTSA AND REQUEST THAT NHTSA INVESTIGATE THE TOTAL NUMBER OF AIR CONDITIONING CONDENSER UNIT FAILURES USED IN SUCH VEHICLES TO IDENTIFY IF A FULL FLEDGED RECALL IS WARRANTED.

NHTSA ODI 11232372

MY DRIVER'S SIDE TAIL LIGHT FLICKERED FOR ABOUT 2 MONTHS BEFORE FINALLY GOING OUT. THE OTHER SIDE IS NOW DOING THE SAME THING. IT HAS 82,301 MILES ON IT.
