2015 GMC YUKON DENALI XL Exterior Lighting Problems

The contact owns a 2015 GMC Yukon Denali XL. The contact stated that the passenger’s side taillight failed to illuminate intermittently while depressing the brake pedal. Over time, the driver’s side taillight also would fail to illuminate with the brake pedal depressed. The contact then received a warranty notice from the local dealer about the failure however, the contact was informed when speaking to the dealer that due to the mileage on her vehicle, the vehicle no longer qualified under the warranty program. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 40,000.

Mileage: 40,000

THE PASSENGER SIDE TAILLIGHT STARTED 'GOING OUT' RIGHT AFTER THE WARRANTY EXPIRED-MEANING, IT WOULD WORK OFF AND ON AT VARIOUS TIMES. THEN THE DRIVERS SIDE TAILLIGHT HAS STARTED DOING THE SAME THING. THIS IS A KNOWN ISSUE WITH THE GMC TAILLIGHTS AND YET GMC HAS YET TO RECOGNIZE ANY ISSUE. THIS IS A MAJOR SAFETY ISSUE FOR ANYONE DRIVING THESE MODELS WITH FAILING TAILLIGHTS. THIS NEEDS TO BE INVESTIGATED

Mileage: 32,000

FAULTY BRAKE-LIGHT AND COSTLY FIX. DEALERSHIP HAS TAILLIGHT ON BACK ORDER SO A REPLACEMENT ISNT EVEN AVAILABLE. DEALERSHIP WANTS $675 JUST FOR THE PART THAT CANT EVEN BE ORDERED. DANGEROUS TO DRIVE THE VEHICLE WITH NO SOLUTION AVAILABLE.

Mileage: 65,000

TAIL LIGHTS INTERMITTENTLY GO OUT WITHOUT NOTICE. THIS CAN HAPPEN WHILE DRIVING OR STATIONARY

Mileage: 67,500

WE HAVE HAD BOTH OUR TAILLIGHTS FAIL. THE BLINKERS STILL FUNCTION BUT BECAUSE THEY ARE LED THEY SAY THEY MUST REPLACE THE WHOLE UNIT. EACH SIDE COST $672. THAT IS OUTRAGEOUS FOR A TAILLIGHT. THERE NEEDS TO BE A WAY TO REPLACE EACH PIECE.

Mileage: 53,000

VEHICLE HAS UNDER 45,000 MILES AND BOTH HEADLIGHTS NEED TO BE REPLACED DUE TO MALFUNCTIONING LED'S FROM WATER INTRUSION. THIS HAPPENS AFTER WASHING MY CAR AND NOW IT WILL NOT PASS STATE INSPECTION DUE TO DRIVER SIDE DAYTIME LED NOT TURNING ON, AND PASSENGER SIDE DRL NOT TURNING OFF. I CAN NOT GET THIS FIXED BECAUSE THE PASSENGER SIDE LIGHT IS ON BACKORDER, YET MY LOCAL DEALER SAID THIS ISN'T A KNOWN PROBLEM. TAKE A LOOK ON THE INTERNET AND IT'S CLEARLY A MANUFACTURING ISSUE (HENCE BACKORDERED HEADLIGHTS)

Mileage: 44,500

BOTH REAR LIGHT ASSEMBLIES HAVE HAD ISSUES. DRIVERS SIDE WAS FIRST, BRAKE LIGHT STOPPED WORKING. REPLACED UNDER WARRANTY. PASSENGER SIDE BRAKE LIGHT AND PARKING LIGHT HAVE NOW STOPPED WORKING, JUST OUT OF WARRANTY. PROBLEM COMES AND GOES DEPENDING ON TEMPERATURE. I WOULD THINK THIS WOULD BE CONSIDERED A SAFETY ISSUE AND BE THE SUBJECT OF A RECALL SINCE IT IS WIDE SPREAD.

Mileage: 72,000

DRIVER'S SIDE, REAR TAIL LIGHT FAILED TO LIGHT WHEN PARKED, OR WHEN DEPRESSING THE BRAKE PEDAL. DEALERSHIP QUOTED JUST UNDER $800 TO REPLACE. HAD LIGHT REPLACED, AND THE SAME THING IS HAPPENING AGAIN. DEALER STATES THAT "LIGHTS GO OUT SOMETIMES."

Mileage: 120,000

BOTH REAR TAIL LIGHTS HAVE GONE OUT.

Mileage: 65,000

APPROXIMATELY 51,000 MILES ON VEHICLE: REAR PASSENGER TAIL LIGHT IS INOP. WE WERE ON A TRIP WHEN WE NOTICED, IF YOU TAP THE SIDE OF IT THE LIGHT WOULD COME ON FOR JUST A SECOND. LED STRIP FOR BRAKE LIGHT IS DEFECTIVE. REPLACEMENT COST IS ABOUT $800 DOLLARS. LOTS OF COMPLAINTS AND ONLINE FORUMS REGARDING THIS ISSUE. GMC REALLY NEED TO RESOLVE THIS ISSSUE. THESE RIGS COST WAY TO MUCH FOR THAT POOR QUALITY!

Mileage: 51,000

THERE IS A FLAW IN THE LED STRIP OF THE REAR TAIL LIGHTS. THE LED STRIP BREAKS OVER TIME DISABLING THE TAIL LIGHTS. THE TAIL LIGHT ASSEMBLY IS SEALED AND MUST EITHER BE REPLACED OR BROKEN INTO SO A JUMPER CAN BE SOLDERED ACROSS THE BREAK TO REPAIR THE TAIL LIGHT.

Mileage: 71,368

FAULTY, POORLY MADE TAIL LIGHTS THAT NEED TO BE ENTIRELY REPLACED (NOT JUST THE BULB) AT MORE THAN $700 EACH. WHEN SPENDING SO MUCH ON A CAR, THIS IS LITERALLY INSANE NOT TO BE COVERED UNDER ANY WARRANTY. GMC DRIVERS DESERVE MORE THAN THIS POORLY MADE LED LIGHT SYSTEM. THE PLASTIC WINDOW TRIM PIECES ALSO DETACH DUE TO CHEAP PLASTIC CLIPS. I'VE HAD TO LITERALLY USE DOUBLE SIDED TAPE AND GLUE TO STICK THEM BACK ON A $70K+ CAR. IT'S HUNDREDS OF DOLLARS TO REPLACE PIECES THAT ARE LITERALLY PART OF THE BODY OF THE VEHICLE.

OUR PASSENGER TAILLIGHT WENT OUT AND THE DEALERSHIP COST TO REPLACE IT WAS $811. I CALLED GMC CUSTOMER SERVICE AND AFTER 4 DAYS AND MULTIPLE PHONE CALLS THE BEST THEY COULD OFFER IN FINANCIAL ASSISTANCE WAS $80. I ASKED THE DEALERSHIP IF I COULD HAVE THE BROKEN LIGHT AND THEY WANTED ME TO PAY $50 TO TAKE IT WITH ME. A GOOGLE SEARCH TURNED UP MANY INSTANCES OF THIS HAPPENING. THE DEALERSHIP TOLD ME THAT THEY REPLACE 1-2 PER WEEK. THE TAILLIGHT REPLACEMENT ON THE YUKON FAMILY IS A SCAM. IT IS UNETHICAL FOR THEM TO CHARGE THAT MUCH FOR A REPLACEMENT WHEN IT IS INOWN TO BE DEFECTIVE. THE CAR IS LESS THAN 4 YEARS OLD AND HAS 66K MILES AND HAS NOT BEEN IN ANY COLLISIONS. JUST NORMAL ROUTINE USE RESULTED IN A COSTLY REPAIR AND, MORE IMPORTANTLY, IRRESPONSIBLE CUSTOMER SERVICE FROM THE GMC EMPLOYEES WHO WERE IN CHARGE OF HANDLING MY CASE.

Mileage: 66,000

'TAKATA RECALL' WE JUST PURCHASED OUR 2015 YUKON DINALI XL DECEMBER 20, 2018 AND HAVE HAD NOTHING BUT PROBLEMS WITH BRAKE LIGHT ( WHILE IN MOTION ) ON DRIVER-SIDE WORKING INTERMITTENTLY, SO WE REPLACED BOTH TAILLIGHTS WITH BRAND NEW ($700) ENCLOSED REAR LIGHT ASSEMBLY AND NOW WE ARE HAVING AN ISSUE WITH DRIVER SIDE ONCE AGAIN. I'M VERY PROUD TO BUY AMERICAN MADE PRODUCTS BUT AFTER SEEING HOW MANY GMC MONTHLY COMPLAINTS WITH THIS SAME ISSUE, YOU WOULD THINK THAT GM WOULD STAND BEHIND THEIR PRODUCT. I KNOW MYSELF BEING IN BUSINESS IF I HAD A COMPLAINS MORE THAN THREE TIMES A MONTH I WOULD TRY MY BEST TO CORRECT THE PROBLEM TO KEEP FROM HAVING A BAD REPUTATION AND HAVE A FUTURE CUSTOMERS!! I TAKE PRIDE IN MY WORK FOR WHAT OUR CUSTOMER PAYS, AND EXPECT THE SAME FOR WHAT I PAY!!

Mileage: 99,000

VEHICLE TAIL LIGHTS AND BRAKE LIGHTS QUIT WORKING. THE LED CIRCUITS BREAK CAUSING THE CONNECTION TO SHORT OUT. BOTH THE TAIL LIGHTS AND BRAKE LIGHTS DO NOT WORK ONCE THE CIRCUIT IS BROKE. THE OWNER CAN'T SIMPLY FIX THE BURNT OUT TAIL LIGHT. ONE MUST COMPLETELY REPLACE THE ENTIRE ASSEMBLY, COSTING UPWARDS OF $1,000 FOR BOTH. THIS IS NOT COST EFFECTIVE AND IS DOWNRIGHT HAZARDOUS WHEN BOTH TAIL LIGHTS GO OUT, FOR BOTH THE OWNER AND OTHER DRIVERS ON THE ROAD. THE TAIL LIGHT ASSEMBLY SHOULD BE ABLE TO RESIST ROAD BUMPS AND VIBRATIONS.

Mileage: 72,000

THE BRAKE LIGHTS WORK INTERMITTENTLY.

Mileage: 61,000

LED LIGHTS IN THE REAR ARE REPEATEDLY DEFECTIVE

Mileage: 60,000

THE PASSENGER SIDE TAILLIGHT HAS FAILED. THIS WAS NOT DUE TO COLLISION, AND IT APPEARS TO BE A WIDE SPREAD ISSUE AFTER READING HUNDREDS OF SIMILAR COMPLAINTS ONLINE.

Mileage: 40,000

TAIL LIGHTS WORK INTERMITTENTLY. SOME TIMES THEY ARE WORKING FINE, AND THEN FOR SOME REASON ONE OR BOTH WILL SHUT OFF AT DIFFERENT TIMES FOR NO APPARENT REASON.

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.

Mileage: 67,000

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

Mileage: 55,000

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!

Mileage: 58,000

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.

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.

Mileage: 60,400

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.

Mileage: 58,754

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

Mileage: 92,000

REPLACED BOTH FRONT STRUTS AT AROUND 91,000 MILES. DEALER SAID STRUTS HAD "LOCKED UP". DEALER REPLACED STRUTS ON FEBRUARY 19, 2018 AT A COST OF $1,818.66. LED BRAKE LIGHTS QUIT WORKING. NOT SURE OF EXACT DATE WHEN THE BRAKE LIGHTS QUIT WORKING.

Mileage: 91,000

VEHICLE STARTED HAVING A VIBRATION AT CRUISING SPEEDS AFTER 100K MILES. DEALERSHIP STATES THE DRIVESHAFT IS WHARPED AND NEEDS REPLACING.. REAR TAILLIGHTS ALSO ARE GOING IN AND OUT INTERMITTENTLY. DEALER CLAIMS THE LEDS ARE BAD AND THE WHOLE LIGHT ASSEMBLY NEEDS REPLACING. I HAVE OWNED MANY VEHICLES AND HAVE NEVER HAD ISSUES WITH A BENT DRIVESHAFT OR DEFECTIVE TAILLIGHTS THAT REQUIRE THE WHOLE ASSEMBLY TO BE REPLACED. THE LIGHT ASSEMBLY IS $750 QUOTED BY DEALERSHIP.

Mileage: 100,000

DRIVER REAR BRAKE LIGHT IS OUT.

Mileage: 52,000

MY PASSENGER SIDE TAIL BRAKE LIGHT WORKS INCONSISTENTLY

Mileage: 32,000

THE TAIL LIGHTS ON BOTH SIDES ARE LED LIGHTS. THEY ARE WORKING INTERMITTENTLY. ONE SIDE WILL SOMETIMES COME BACK ON IF I BUMP IT WITH MY HAND. MY VEHICLE HAD LESS THAN 50,000 MILES ON IT WHEN THIS STARTED OCCURRING BUT WAS OUT OF WARRANTY. I HAVE BEEN TOLD THAT IT WILL COST APPROXIMATELY $1500 TO FIX. I HAVE ALSO BEEN TOLD BY THE DEALER THAT THIS IS A COMMEN PROBLEM WITH THE 2015 MODEL. I FEEL THAT THIS IS AN EXTREME SAFETY ISSUE AND SHOULD BE REPLACED BY GM THROUGH A RECALL. BECAUSE THE LIGHTS WORK INTERMITTENTLY, IT IS OBVIOUSLY A SHORT OR DEFECT OF SOME KIND.

Mileage: 45,000

AT 44K MILES ON THE VEHICLE, NOTICED THAT THE LEFT REAR BRAKE LIGHTS (LEDS) WERE NOT ILLUMINATING WHEN THE BRAKE WAS APPLIED, AT REST OR WHILE DRIVING. THIS INCLUDES BOTH THE TAIL LIGHTS AND BRAKE LIGHTS. PHYSICALLY TAPPING ON THE HOUSING LIGHTS THEM UP TEMPORARILY, BUT IT DOES NOT STAY LIT. DEALER WANTS OVER 700 DOLLARS TO REPLACE THE ENTIRE ASSEMBLY. DOING RESEARCH ONLINE SHOWS MANY MANY OTHER OWNERS WITH THESE LED TAIL LIGHT ASSEMBLYS WITH THE EXACT SAME ISSUE. THE PART IS DEFECTIVE, IN THAT THE CIRCUIT INSIDE THE ASSEMBLE BRAKES, AND THE LIGHTS WILL NOT LIGHT UP. THE LED BULBS THEMSELVES STILL WOULD WORK, IF THE CIRCUIT TO THEM WAS NOT DEFECTIVE. SOMEONE NEEDS TO STEP UP AND CALL OUT THE MANUFACTURE ON THIS ONE. ITS A MANUFACTURER DEFECT, NOT BAD BULBS! PLEASE HELP. HERE IS ONE FORUM THAT HAS MANY PEOPLE TALKING ABOUT IT. HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-T53845_DS768963

RIGHT SIDE TAIL LIGHT IS NOT WORKING TRANSMISSION IS CLUNKS WHEN SELECTING DRIVE FROM REVERSE. WHEN ROLLING SLOW IN A PARKING LOT, SOMETIMES THE TRANSMISSION HAS A VERY HARSH CLUNK AS IF SOMEONE HAS HIT ME IN THE REAREND. THE STEERING COLUMN HAS A POPPING NOISE WHEN TURNING LEFT.

Mileage: 61,500

LED BRAKE LIGHT ALREADY BURNT OUT AND ONLY 2 YEARS OLD. OVER $600 TO FIX A LIGHT THAT IS SUPPOSE TO HAVE A UNLIMITED LIFE....

Mileage: 87,000

VEHICLE WAS MANUFACTURED MID 2014, 2015 MODEL, CURRENTLY HAS JUST OVER 52K MILES. DRIVERS SIDE TAILLIGHT IS BEING TEMPERAMENTAL; NO WARNING LIGHTS INSIDE TO INDICATE A FAILURE. WHEN YOU PRESS ON THE TAILLIGHT IT STILL ILLUMINATES, THERE ARE NO LEDS OUT, BUT TAILLIGHT AND BRAKE LIGHT WON'T ILLUMINATE. CALLED THE DEALERSHIP AND THEY'VE STATED IF FOUND FAULTY IT REQUIRES COMPLETE REPLACEMENT OF THE TAILLIGHT AND IT WAS QUOTED AT ROUGHLY $850 INSTALLED, WHICH SEEMS REALLY EXCESSIVE WHEN A TAILLIGHT GOES OUT.

Mileage: 52,220

THE BRAKE LIGHTS IN THIS VEHICLE ARE FAULTY. MY DRIVER SIDE WENT OUT IN JULY AND IN THE SAME MONTH MY PASSENGER SIDE WENT OUT. THE BULBS ARE NOT BURNED OUT AND IT HAS TO DO WITH THE WIRING. GMC WILL NOT COVER THE SECOND LIGHT OR PROVIDE COST ASSISTANCE BECAUSE I AM OUT OF WARRANTY DUE TO MILES.
