THE DRIVERS SIDE REAR TAIL LIGHT STOPPED WORKING. CHECKED MULTIPLE FORUMS AND THIS ISSUE CONTINUES TO BE A CHRONIC ISSUE FOR OWNERS OF THIS VEHICLE.

NHTSA ODI 11110252

BOTH PASSENGER AND DRIVERS SIDE BRAKE LAMPS, TURN SIGNALS AND RUNNING LAMPS SHORT OUT AND STOP WORKING. WHEN VEHICLE IS UNDER WARRANTY, LAMPS ARE REPLACED WITH NEW UNITS, THAT ARE ALSO FAULTY AND EVENTUALLY FAIL, IN ANYWHERE FROM 1 WEEK TO 1 YEAR. GM IS WELL AWARE OF THIS WIDESPREAD, NATIONWIDE PROBLEM, YET REFUSES TO ISSUE A RECALL, AND CHARGES $1500+ THE REPLACE THE UNITS WITH NEW OEM, THAT ARE STILL FAULTY.

DRIVER REAR BRAKE LIGHT IS OUT.

LED TAIL LIGHTS/BRAKE LIGHTS NOT WORKING DUE TO BAD CIRCUIT BOARDS IN THE LAMP HOUSING WHEN IN MOTION OR IN PARK. GM SAYS THERE IS A UPGRADE KIT BUT THEY MADE THEM WHERE YOU CAN NOT GET INTO THEM AND FIX THEM WITHOUT REPLACING THE WHOLE UNIT WHICH RUNS AN AVERAGE OF $650 AND UP EACH. BRAKE LIGHTS ARE A SERIOUS SAFETY HAZARD IF THEY DO NOT WORK. I HAVE BEEN ON MANY BLOG SITES WITH HUNDREDS OF PEOPLE EXPERIENCING THE SAME ISSUES ON THE SAME VEHICLE. GM SHOULD RECALL THEM AND REPLACE THEM WITH THE UPGRADE KIT BECAUSE IT IS A MANUFACTURING DEFECT AND A SAFETY HAZARD ON THE ROAD.

NHTSA ODI 11104872

BRAKE LIGHTS GO OUT (BOTH SIDES) INTERMITTENTLY. STARTED HAPPENING AT LESS THAN 1YR OLD, AND CONTINUES TO HAPPEN.

NHTSA ODI 11104532

THE FIRST COMPLAINT IS ABOUT THE TAII LIGHTS. ONE OF THE RUNNING LIGHTS DOES NOT ILLUMINATE. I FIGURED IT WOULD BE A LAMP. NOPE. $500-$800 TO REPLACE THE ENTIRE ASSEMBLY! APPARENTLY IT IS SO COMMON THERE ARE SEVERAL PEOPLE ONLINE THAT HAVE BUSINESSES REPAIRING THEM.

NHTSA ODI 11104143

RIGHT BRAKE LIGHT NO LONGER WORKS. UNABLE TO REPLACE BULB AND HAVE TO SPEND 775 ON A NEW LIGHT HOUSING SINCE THESE ARE NOT SERVICEABLE LIGHTS

NHTSA ODI 11103590

PASSENGER SIDE TAIL LIGHT WORKS ONLY INTERMITTENTLY. THE TURN SIGNAL STILL FUNCTIONS, BUT THE BRAKE LIGHT ITSELF FAILS. I WAS PULLED OVER MY POLICE FOR A NON-FUNCTIONING TAIL LIGHT. NEW LIGHT ASSEMBLY IS $660 PER LIGHT TO REPLACE AT THE DEALERSHIP. THIS PROBLEM OCCURS REGARDLESS OF THE VEHICLE BEING IN MOTION OR NOT.

NHTSA ODI 11103592

BRAKE LIGHTS WORKING INTERMITTENTLY. OCCASIONALLY EITHER THE RIGHT OR LEFT WILL NOT LIGHT UP. NOT REPEATABLE OR CONSISTENT AND DEALER NOTES NO SERVICE BULLETINS OR CODES.

NHTSA ODI 11103354

THE REAR LED BRAKE LIGHTS ARE INTERMITTENTLY NOT WORKING. IT APPEARS TO BE A BAD CONNECTION OR FAULTY LIGHT BOARD INSIDE THE HOUSING. WHEN THE TEMPERATURE GETS HOT, THE BRAKE LIGHTS STOP WORKING. IT CAN HAPPEN AT ANY TIME, WHEN DRIVING OR PARKED. NOT HAVING BREAK LIGHTS ON A VEHICLE IS EXTREMELY DANGEROUS. THERE IS NOT A WAY TO CHANGE THE BULBS OR BOARD WITHOUT CHANGING THE ENTIRE LIGHT HOUSING. AFTER A QUICK GOOGLE SEARCH, THIS IS A SERIOUS SAFETY PROBLEM AFFECTING A HUGE NUMBER OF PEOPLE WITH THE SAME EXACT ISSUE. THOUSANDS OF PEOPLE ARE EXPERIENCING THE SAME PROBLEM AND IT APPEARS TO BE A MANUFACTURING KNOWN ISSUE THAT THE DEARLERAHIPS ARE CASHING IN ON.

TL* THE CONTACT OWNS A 2015 GMC YUKON. WHILE DRIVING VARIOUS SPEEDS OR WHILE THE VEHICLE WAS STATIONARY, THE BRAKE LIGHTS FAILED TO ILLUMINATE WHEN THE BRAKE PEDAL WAS DEPRESSED. THE FAILURE OCCURRED ON SEVERAL OCCASIONS. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO ALLEN CADILLAC GMC (28332 CAMINO CAPISTRANO, LAGUNA NIGUEL, CA 92677, (949) 485-3700) WHERE IT WAS DIAGNOSED THAT THE LED CIRCUIT PANEL WAS FAILING AND NEEDED TO BE REPLACED.

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.

LED CIRCUIT BOARD FAIL. DEALERSHIP WILL FIX FOR OVER $2000 WITH THE OLD FAULTY PARTS INSTEAD OF THE NEW PARTS. HUNDREDS OF PEOPLE HAVE HAD THIS SAME ISSUE AND IT NEEDS TO BE ADDRESSED.

NHTSA ODI 11103095

HEADLIGHT HAS WATER CONDENSATION IN IT AND DEALERSHIP SAYS IT'S A SEALED UNIT SO THE WHOLE HEADLIGHT NEEDS REPLACED AND IF IT HAPPENED TO THE PASSENGER SIDE IT'S MOST LIKELY GOING TO HAPPEN TO THE DRIVER SIDE 1 HEADLIGHT COST $1,200 TO REPLACE AND LABOR IF GMC KNOWS THIS IS A PROBLEM WITH THE 2015 YUKONS HOW COME SOMETHING IS NOT BEING DONE ABOUT IT BECAUSE $1,200 IS NOT A SMALL AMOUNT OF MONEY!

NHTSA ODI 11102581

RIGHT REAR TAILLIGHT WORKS INTERMITTENTLY. IT IS AN LED ASSEMBLY, NO BULBS CAN BE REPLACED. ONLY WAY TO REPAIR IS TO REPLACE TOTAL ASSEMBLY AT COST OD WELL OVER $650.00. THIS IS A DESIGN OR PRODUCT FLAW THAT GM IS AWARE OF AND SHOULD BE REPLACE UNDER WARRANTY. THEY DENY THERE IS A PROBLEM.

NHTSA ODI 11102453

LED TAILLIGHT IS ALREADY OUT - SHOULD LAST FOR 10+ YEARS, CAR IS OUT OF WARRANTY, DEALER CHARGES $750 TO REPLACE AND CAN'T GUARANTEE IT WON'T HAPPEN AGAIN. DEALER CAN'T EXPLAIN WHY THE LIGHT IS OUT, SAYS IT JUST HAPPENS

NHTSA ODI 11101771

TAIL LIGHTS INTERMITTEDLY DO NOT WORK. SOMETIMES IT'S THE RIGHT SIDE AND SOMETIMES IT'S THE LEFT SIDE. I'VE SEEN MANY OTHER COMPLAINTS ON LINE AS I HAVE BEEN RESEARCHING FOR PRICING.
