2015 GMC YUKON Exterior Lighting Problems

Rear tail lights go out intermittently caused by a defect in the vehicle manufacturer’s process in which the circuit board is broken in certain areas.

The contact owns a 2015 GMC Yukon. The contact stated that while depressing the brake pedal, added pressure was needed before the vehicle came to a stop. The contact stated that the vehicle hesitated or jumped before coming to a stop. Additionally, the contact stated the transmission was slipping. The contact stated that while driving at various speeds, the vehicle stalled before self-correcting. The contact also stated that while idling at a stop light and attempting to accelerate, the vehicle hesitated, but gradually accelerated as needed. The contact stated that the rear taillight intermittently failed to illuminate. The contact stated that the check engine warning light was illuminated. The transmission fluid was flushed; however, the failure recurred. The vehicle was taken to the dealer who diagnosed the vehicle and determined that the transmission was fractured, and the light bulbs needed to be replaced. The transmission was not repaired or replaced....

My vehicle is currently in the shop getting the motor worked on for a bad lifter. From the information the mechanic provided me this is a common issue with the vehicles that have the Active Fuel Management system. They are seeing many of these vehicles have to come in and have very expensive repairs. My first quote I received was $16, 000, they told me I needed a whole new motor and this assessment cost me $365 and a rental car while they looked at the truck. Now it is in the shop again and the estimate is $6000 to machine the cams as there are metal shavings in my oil. I had to again rent a rental vehicle and have not had my truck for a week. This is the third mechanic that has seen multiple of these motors have to be replaced or repaired due to this issue....

Both tail lights fail. I just bought this vehicle at Ewald Automotive in Oconmowoc Wi a month ago with 100k and I know they were aware of the problem and so is GMC. I am not paying 900 bucks for each tail light. They are absolute junk. The left side someone already messed with it because there is electrical tape on it. Ewald laughed in my face.

The taillights started to randomly go in and out. The driver side taillight stopped working but the passenger side taillight still worked. Then a day later the driver side taillight worked, but the passenger side taillight didn’t work. The next day we were going to look into this issue, and the driver and passenger side taillights were working, so we halted. We kept an eye on it and they seemed to continue to work for a few days with no issues, so drove it 20 miles to work. When I left work it was dark and I had a coworker check my brake lights before leaving and the running lights and brake lights were indeed working. By the time I arrived at home, I had no running or brake lights. This is and was a danger to others and myself as this could’ve caused an accident driving and the taillights...

Both tail lights have stopped working. I purchased in 2019 with 60k miles and by the time the first tail light failed, I was over the 72k limit. If these lights failing was an issue before, it still is an issue and the special warranty should be extended to ensure replacement of faulty items.

Numerous reports of taillights and headlights not working properly and no recall like it should be

There was recall for N182180270 Tail Lamps Inoperative, for some reason my vehicle being a 2015 was not included. This issue is ongoing with my 2015 Yukon Denali and is dangerous while operating, it recently started and is intermittent. Also my vehicle has issues with hard shifting and jerking intermittently when taking off.... also a known issue for this year and make/ model of vehicle

Rear passenger running lights just stopped working. I have seen several people with the same issue. I think there should be a recall for GM to fix the issue they are clearly aware of.

Tail lights keep going out and have been replaced

LED brake light wiring comes undone causing brake lights to go out.

Driver Rear brake led light not working

Both my tail lights have failed. Dealer wants insane amount of money for new ones, so I opened up the lights and there is an obvious design flaw in the lights, to me it seems intentional at worst, incompetent at best. I am an electrical engineer, and there is no reason they should put a friction connection in the LED power bar, it is a glaring design flaw. Also having steering assist issue at low speed which was an issue that was supposed to be fixed in a previous recall service, but it is still malfunctioning.

Break like when out and only solution iam being given is to replace the whole housing at 800$ and it seems this a faulty component.

Steering locks up at lower speeds or when turning into a parking lot all the ligths shut off at the same time the steering does it has happened more at night lights flicker both interior lights and exterior lights a/c shuts off radio shuts off i have went to different dealers and have not been able to fix this problem even doh i show them videos of what it does both my wife and i have almost had a few accidents because of this

Right brake light and tail light quit working for a few days, then returned to normal operation, both worked fine for a week then the left side went out and also returns for a few days. Now both are out except for one led per side per cluster. No brake lights except for the one over the gate. And turn signals work as they should.

Tail Lights don't work. Have seen several complaints about this problem. There is currently a lawsuit concerning this. GMC will only cover replacement if car has less than 72,000 miles. The replacement lights cost about $800 each. Having it looked at now. Fear that I will have to pay replacement costs.

Drivers side tail light intermittently works, doesn't work all the time. Passenger side brake light stays on continuously, never changes.

STOP AND TAIL FUNCTIONS INSIDE THE TAIL LAMPS HAVE BECOME INOPERATIVE. PURCHASED VEHICLE USED AND FALLS JUST OUTSIDE OF THE SPECIAL COVERAGE ADJUSTMENT; N182180270. THIS IS STILL VERY MUCH A SAFETY ISSUE, EVEN THOUGH IT'S 1 MONTH LONGER THAN THE 6 YEAR CUTOFF.

PURCHASED A 2015 YUKON DENALI BACK IN NOVEMBER 2019. SINCE PURCHASING THE VEHICLE WE HAVE HAD TO REPLACE THE BATTERY, TRANSMISSION, AC COMPRESSOR AND EXPANSION VALVE (WHICH STILL ISN'T WORKING CORRECTLY, BECAUSE IT DOESN'T BLOW COLD AIR), AND THE BLACK PANELS THAT ARE IN BETWEEN THE WINDOWS. ALSO, BOTH TAIL LIGHTS HAVE DECIDED TO QUIT WORKING.... WHICH CONCERNS ME GREATLY BECAUSE CARS BEHIND ME DON'T KNOW WHEN I AM STOPPED OR APPLYING THE BREAKS. STOPPED OR HAVE MY FOOT ON THE BREAK.

PASSENGER SIDE TAIL LIGHT/BRAKE LIGHT GOES OUT INTERMITTENTLY AT RANDOM. I PURCHASED CAR USED IN FEBRUARY 2020 AND WAS INFORMED SOON AFTER BY FRIEND THAT MY TAIL LIGHT WAS OUT WHEN LEAVING THEIR HOME. IT WAS WORKING THE NEXT DAY WHEN I CHECKED. I NOW WATCH IT AND SEE THAT IT WORKS ONLY SOMETIMES. COST TO REPLACE IS APPROXIMATELY $700 ASSUMING ONLY A REPLACEMENT LIGHT IS NEEDED AND NOTHING ELSE IS WRONG. BASED ON THE MULTIPLE COMPLAINTS I HAVE SEEN THIS SOUNDS LIKE A WIRING ISSUE THAT SHOULD BE A MANUFACTURER RECALL FOR SAFETY REASONS.

REAR BREAK LIGHT . INTERNAL WIRING OF THE TAIL LIGHTS CRACKS LEADING TO TAIL LIGHT FAILURE. THE FAILURE DOES NOT TRIGGER ANY WARNINGS AND THE DRIVER IS UNAWARE OF THIS FAILURE UNLESS THEY PREFORM A PRE TRIP INSPECTION.

TL* THE CONTACT OWNS A 2015 GMC YUKON. THE CONTACT STATED THAT WHILE OPERATING THE VEHICLE, IT WAS DISCOVERED THAT THE REAR BRAKE LIGHTS WERE INOPERABLE. THE CONTACT DETERMINED THAT THE FAILURE WAS INTERMITTENT BY TAPPING ON THE LIGHT HOUSING. THE CAUSE OF THE FAILURE WAS NOT DETERMINED. THE LOCAL DEALER BEN MYNATT BUICK LOCATED AT 289 CONCORD PKWY S, CONCORD, NC 28027 WAS NOTIFIED OF THE FAILURE. THE MANUFACTURER WAS CONTACTED BUT NO ASSISTANCE WAS OFFERED. THE FAILURE MILEAGE WAS 79,800.

BOTH REAR TAIL LIGHT ASSEMBLIES WENT BAD. THE LEFT ONE IN APRIL OF 2019 AND THE RIGHT ONE IN JANUARY OF 2021. SERVICE ADVISORS IN THE 2 DEALERSHIPS I DEAL WITH CLAIM THE DO NOT KNOW ANYTHING ABOUT IT. YET A NUMBER OF REPAIR SHOPS ON THE INTERNET KNOW OF THIS PROBLEM IN 2015 TO 2019 YUKON'S BECAUSE THEY REPAIR THEM. FUNNY THAT GM DOES NOT. I SENT THE 1ST ONE OUT AND IT WAS REPAIRED FOR WELL UNDER THE COST OF A NEW ONE. I COMPLAINED AGAIN TO THE SERVICE ADVISOR ABOUT THIS ONE TO NO AVAIL. GOING TO SEND IT OUT FOR REPAIR AS WELL. INCIDENTALLY THEY COVER THE REPAIR WITH A LIFETIME WARRANTY.

BOTH REAR TAIL LIGHTS ARE INOPERABLE AND THE DEALER WANTS OVER $800 TO REPLACE. I'M OVER THE MILEAGE LIMIT FOR THE RECALL SO I'M OUT OF LUCK.

THE BACK PASSENGER BRAKE LIGHT HAS BEEN FUNCTIONING INTERMITTENTLY FOR THE PAST 15 MONTHS. WE HAVE BEEN STOPPED BY OTHER VEHICLES LETTING US KNOW 'YOUR TAILIGHT IS OUT' BUT WHEN WE GET HOME TO LOOK AT IT, THE LIGHT IS FUNCTIONING JUST FINE. AFTER MULTIPLE OCCURRENCES BEING TOLD THE SAME THING, WE TOOK THE YUKON INTO THE DEALER TO HAVE IT CHECKED. THE DEALER LET US KNOW THAT THIS IS A KNOWN ISSUE WITH THIS DESIGN, AND THAT THERE IS A RECALL/WARRANTY FOR THIS ISSUE. HOWEVER - OUR YUKON HAD 76,000 MILES AT THE TIME WE TOOK IT IN, AND THE RECALL ONLY COVERED VEHICLES LESS THAN 72,000 MILES OR 6YEARS FROM DATE OF SERVICE. NOW - I HAVE READ MANY FORUMS AND SEEN ALL ACROSS THE COUNTRY THAT THIS ISSUE IS OCCURRING DUE TO A POOR DESIGN FROM GM. LIMITING THE RECALL TO A CERTAIN MILEAGE IS [XXX] WHEN...

SO MY BRAKE LIGHT ON REAR ALL HAVE GONE OUT DUE TO BAD LED LIGHTS OR SOME KNOWN COMPONENT GOES BAD. #2. FUEL PUMP IS BAD. #3 RADIATOR HAS A CRACK IN IT. THIS IS A 2015 YUKON

DRIVER TAIL LIGHT WORKS INCONSISTENTLY

PASSENGER REAR BRAKE LIGHTS QUIT WORKING. APPEARS TO BE A DEFECT IN THE DESIGN THAT CAUSES A BREAK IN THE CIRCUIT ON THE LIGHT ASSEMBLY. REPAIR CAN BE MANUALLY DOWN BY CUTTING THROUGH PLASTIC OF ASSEMBLY AND SOLDERING BREAK, OR REPLACEMENT OF ENTIRE LIGHT ASSEMBLY. NO ACCIDENTS - JUST NORMAL DRIVING.

MY PASSENGER BRAKE LIGHTS STOPPED WORKING. APPARENTLY THE ONLY WAY TO FIX IS TO BUY A WHOLE NEW UNIT WHICH COSTS $300-$500.

REAR TAIL LAMPS BOTH SIDES ARE OUT

TAIL LIGHTS GO OUT. I HAVE READ MULTIPLE POSTS ABOUT THIS ISSUE, BUT YET THERE IS NO SAFETY RECALL ISSUED FOR THIS. IT IS VERY EXPENSIVE TO REPLACE THE LIGHTS AND I AM AFRAID IF I DO, THE SAME ISSUE WILL EXIST.

HAVING ISSUES WITH THE TAIL LIGHTS EVER SINCE I GOT THE VEHICLE. FIRST IT WAS ONE LIGHT COMPLETELY OUT. THEN IT WORKED FOR AWHILE, AND NOW BOTH LIGHTS ARE INTERMITTENTLY WORKING. THE SIDE YELLOW LIGHTS WORK ON BOTH BUT THE RUNNING LIGHTS AND THE BRAKE LIGHTS ALL DONT WORK ALMOST ALL OF THE TIME. UPON READING UP ON THE INTERNET, MANY MANY SITES AS WELL AS LOCAL PEOPLE WITH THE SAME VEHICLE, ALL STATE THEY HAVE THE EXACT SAME ISSUE WITH THEIR TAIL LIGHTS. IT SEEMS TO BE A VERY COMMON ISSUE WITH THE SAME PIECES FAULTING IN ALL OF THESE YUKONS. DOESN'T MATTER IF VEHICLE IS STOPPED OR MOVING THEY HARDLY EVER WORK.

THIS 2015 YUKON SLT HAS 2 FAILED REAR TAILLIGHTS AND BRAKE LIGHTS. THERE IS NO INDICATION OF THIS FAILURE IN THE INSTRUMENT PANEL. MY WIFE WAS ADVISED BY TEXT FROM A FRIEND THESE LIGHTS WERE OUT. THE REPLACEMENT ASSEMBLY IS APPX $500.00 PER SIDE PLUS INSTALLATION. I WAS ADVISED THIS IS NOT A WARRANTY ITEM AND IT IS ALSO A COMMON FAILURE ON THESE VEHICLES. NOT SURE WHEN THE FAILURE OCCURRED. THE 3RD RAISED LIGHT WAS OPERATIONAL WHEN THE BRAKES WERE USED. FIRST NOTICED AROUND JULY 10, 2020. I HAVE SEVERAL CARS FROM 2002 ON WHICH WARN OF A LIGHT FAILURE. THESE LED LIGHTS WERE ADVERTISED TO LAST FOR EXTENDED PERIODS. THIS ISSUE IS DANGEROUS AND UACCEPTABLE.

I BOUGHT MY GMC YUKON IN MARCH OF 2019 ABOUT A WEEK LATER I HAD PEOPLE INFORM ME MY BRAKE LIGHTS WERE NOT WORKING. I WOULD CHECK AT NIGHT AND THEY WOULD. A FEW MONTHS LATER I NOTICED IT MYSELF, THEY WOULD WORK ONE MINUTE BUT NOT THE NEXT. DECEMBER OF 2019 I GET A LETTER FROM GMC STATING THEY KNOW 2015 MODEL GMC YUKON VEHICLES MAY HAVE A CONDITION WHERE THE BRAKE LIGHTS INTERMITTENTLY DO NOT ILLUMINATE. I COULD HAVE IT DONE IF MY SUV WAS NOT OVER 72K MILES BUT IT WAS WHEN I BOUGHT IT. SO THAT DOESN'T HELP ME AND THEY WANT $2K TO FIX IT. I CALLED TO SEE WHAT THEY COULD DO AND THEY TOLD ME THIS WASN'T A SAFETY ISSUE. IF THEY DO WORK AND SOMEONE DOESN'T SEE I AM BRAKING, MY KIDS OR FAMILY ARE IN THE BACK SEAT, HOW IS THAT...

BOTH TAILLIGHTS INTERMITTENTLY STOP WORKING. *TR

THE REAR TAIL LIGHT KEEPS GOING OUT. IT WAS ALREADY REPLACED ONCE AT MY DEALERSHIP. NOW THE SAME LIGHT LESS THAN 3 YEARS IS NOT FUNCTIONING. POSING A SAFETY CONCERN AS OTHER VEHICLES WOULD NOT SEE ME AT A COMPLETE STOP DUE TO MY REAR PASSENGER LIGHT NOT WORKING. THIS SHOULD BE A SAFETY RECALL. ITS A VERY COMMON THIS IS A MANUFACTURING DEFECT AND GMC SHOULD HAVE THIS FIXED ASAP. TRIED CALLING GMC AND THEY SAID THEY WOULD NOT HELP ME WITH THE REPAIR COST OF MY REAR PASSENGER TAIL LIGHT. I STATED THIS WAS A SAFETY ISSUE AND REQUIRED THEIR ATTENTION. TO NO AVAIL I WAS DENIED ANY ASSISTANCE. THE LIGHT ITSELF AT MY DEALERSHIP IS $800 NOT INCLUDING LABOR. THIS IS MY EVERY DAY FAMILY DRIVER CAR. I HAVE BEEN STOPPED BY COPS AND GIVEN WARNINGS AND BY OTHER PASSER BY'S THAT MY BRAKE LIGHT IS NOT...

MANUFACTURE DEFECTIVE , FRONT DRIVER SIDE HEADLIGHT ASSEMBLY HAS HIGH CONDENSATION WHICH CONTINUES TO GET WORSE. IT HAS CAUSED THE LIGHT TO MALFUNCTION AND NOW WILL NOT WORK. I WAS TOLD BY A MECHANIC THAT THE WHOLE HEADLIGHT ASSEMBLY HAS TO BE REPLACED BECAUSE IF NOT THE BULBS WILL CONTINUE TO BURN OUT DUE TO THE CONDENSATION. *TR

RIGHT REAR TAIL LIGHT AND BRAKE LIGHT STOPPED WORKING. IT IS AN LED LIGHT AND VERY EXPENSIVE. THIS IS A SAFETY CONCERN AS LACK OF A BRAKE LIGHT ON ONE SIDE IS IN VIOLATION OF LEGAL REQUIREMENTS. LED LIGHTS SHOULD NOT QUIT FUNCTIONING AFTER 5 YEARS AND 85,000 MILES. *TR

REAR TAIL LIGHT CIRCUIT BOARDS BREAKING AND CAUSING BRAKE LIGHTS OR TAIL LIGHTS TO FAIL OR NOT WORK. *TR

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...

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

IN MARCH 2019 PASSENGER SIDE TAIL LIGHT STARTED WORKING INTERMITTENTLY- TOOK IT TO THE DEALER AND HAD IT REPLACED ($800) ONE YEAR LATER (MAY 2020) DRIVER SIDE TAIL LIGHT STOPPED WORKING COMPLETELY. *TR

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

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

BRAKE LIGHT GOES OUT DUE TO WIRING ISSUES. *TR

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!

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.

THE LEFT TAIL LIGHT WAS NOT TURNING ON WHEN STARTING THE CAR. LEFT TAIL LIGHT DOES NOT COME ON WHEN PRESSING BRAKE. AT FIRST, IT WAS INTERMITTENT AND NOW IT DOES NOT COME ON AT ALL.
