I HAVE THIS EXACT SAME PROBLEM...I CAN NOT AFFORD TO FIX IT. BRAKE LIGHT STOPPED WORKING, GMC WANTS TO REPLACE THE WHOLE ASSEMBLY FOR $800. MY WARRANTY HAS EXPIRED BUT I THINK GMC SHOULD HAVE AWAY TO REPAIR THE LIGHT INSTEAD OF REPLACING THE WHOLE ASSEMBLY. A RECALL ON THIS SHADY WAY OF GETTING THE CONSUMER HARD EARNED MONEY. BECAUSE IT SHOULD LAST LONGER. I CAN?T DRIVE MY CAR IN FEAR OF GETTING A TICKET. PLEASE HELP

NHTSA ODI 11101394

REAR BLACK LIGHTS FAIL... KNOWN ISSUE... ONLY FIX IS $750... GMC KNOWS IT IS AN ISSUE AND HASN'T DONE A RECALL... MOST CARS YOUR TAIL LIGHT GOES OUT $10 TO FIX... GMC $750

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.

DRIVER SIDE TAIL LIGHT AND BREAK LIGHT DOES NOT WORK INTERMITTENTLY. UNDER 32K MILES. DEALER DOES NOT COVER AS THERE IS NO RECALL.

NHTSA ODI 11099413

LED BRAKE LIGHT IS FAULTY. DEALERSHIP WANTS OVER $800 FOR REPAIR OF SINGLE LIGHT. SEEMS TO BE A KNOWN PROBLEM FOR THIS MAKE AND MODEL.

NHTSA ODI 11099426

THE VEHICLE HAS UNDER 40,000 MILES AND THE BRAKE LIGHTS HAVE FAILED. THESE ARE LED TYPE BRAKE LIGHTS SO THEY SHOULD LAST MUCH LONGER. YOU CAN NOT REPLACE THE INDIVIDUAL BULBS. YOU MUST REPLACE THE WHOLE TAIL LIGHT ASSEMBLY AT THE COST OF $750 EACH. A WARNING ON THE DASH NEVER APPEARED TO NOTIFY ME THAT THE BRAKE LIGHT WAS NOT FUNCTIONING.

NHTSA ODI 11099252

BOTH BRAKE LIGHTS FAILED WITHIN WEEKS OF EACH OTHER - AROUND 60K MILES. FAULTY LED CIRCUIT BOARDS. LIGHT ASSEMBLIES ARE NOT REPAIRABLE BY DEALERSHIP. NEW ASSEMBLY OVER $500 EACH. GM TAKES NO RESPONSIBILITY IN RESOLVING THE ISSUE. UNACCEPTABLE! NO MORE GMS FOR MY FAMILY! .. AND THAT INCLUDES CHEVY.

TAIL LIGHT HAS BEEN FLICKERING FOR MONTHS AND NOW IS OUT. GMC WILL NOT FIX BECAUSE I AM 4 MONTHS OUT OF WARRANTY. I ONLY HAVE 18,000 MILES ON MY YUKON.

NHTSA ODI 11099093

VEHICLE FRONT HEADLIGHT AND TAILLIGHT LEDS ARE OUT. THREE OUT OF THE FOUR LIGHTS HAVE GONE OUT IN THE LAST MONTH.

NHTSA ODI 11098630

FAULTY BRAKE LIGHTS. GOES OUT INTERMITTENTLY AND THEN STOPS WORKING ALTOGETHER. CANNOT BE FIXED OR REPAIRED WHETHER IT IS ONE LED LIGHT OR MANY- THE WHOLE LED DISPLAY IS FAULTY AND STOPS WORKING. DEALER WAS GOING TO CHARGE $750 TO FIX- FOR JUST 1 REAR BRAKE LIGHT. NOT HAVING FULLY FUNCTIONING BRAKE LIGHTS ON A 3 YEAR OLD CAR IS UNACCEPTABLE AND SHOULD BE UNDER RECALL- IT'S A SAFETY ISSUE AND OBVIOUSLY A FAULTY PART WHEN THERE ARE NUMEROUS COMPLAINTS AND BLOG POSTS ABOUT THE SAME ISSUE.

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.

I WAS DRIVING DOWN THE ROAD AND SOMEONE CLEARLY (DUE TO THE LOUD SCREECHING OF THE TIRES) ALMOST REAR ENDED ME. THANKFULLY THEY WERE ABLE TO STOP JUST BEFORE HITTING MY VEHICLE. HE CAUGHT ME AT A STOP LIGHT AND INFORMED ME THAT BOTH OF MY BRAKE LIGHTS WERE OUT UNBEKNOWNST TO ME. I HAVE SINCE TAKEN THE VEHICLE TO THE DEALERSHIP, BUT THERE IS AN ISSUE WITH THE BRAKE LIGHT SYSTEM/PARTS FOR THIS VEHICLE. THE BRAKE LIGHT WILL WORK SPORADICALLY (WITHOUT ANY KNOWLEDGE OF AN ISSUE). THE MANUFACTURER HAD TO HAVE KNOWN THERE WAS AN ISSUE WITH THIS PART DUE TO THE OWNER'S MANUAL EVEN STATING "CONTACT GMC DEALERSHIP" WITHOUT GIVING ANY TROUBLESHOOTING ADVISE ON THE LIGHT. THE PART IS ~$650 TO REPLACE, BOTH OF MY BRAKE/TAIL LIGHTS HAVE GONE OUT WITHIN A 3 WEEK PERIOD OF EACH OTHER AND THE DEALERSHIP DIDN'T SEEM SURPRISED AT ALL OF THIS ISSUE.

NHTSA ODI 11096470

THE LED BRAKE LIGHTS FAIL DUE TO A MANUFACTURING ISSUE. IN LESS THAN 3 YEARS AND 40,000 MILES THE VEHICLE HAS GONE THROUGH 3 LED BRAKE LIGHT ASSEMBLIES. THERE IS NO WARNING WHEN THEY FAIL.

NHTSA ODI 11084062

REAR LED (BREAK LIGHT) DOES NOT WORK TURN SIGNAL, BACKUP WORKS. COST IS OVER $500 TO REPLACE THIS IS OUTRAGEOUS EXTENDED WARRANTY DOES NOT COVER LIGHT BULBS NOW I KNOW WHY THIS SHOULD BE A FACTORY DEFECT.

NHTSA ODI 11084220

REAR TAILLIGHT & BRAKE LIGHT - INTERMITTENT OPERATION OF REAR LED MARKER AND BRAKE LIGHT ON DRIVER SIDE. VEHICLE HAS < 30,000 MILES. GM SELLING DEALER AWARE OF ISSUE WITH NO ACTION TAKEN.

NHTSA ODI 11082115

THE BRAKE LIGHTS ON MY 2015 ARE DEFECTIVE. THE DRIVER SIDE LIGHT WENT OUT ABOUT NINE MONTHS AGO AND NOW THE PASSENGER SIDE LIGHT IS OUT. OUR LOCAL DEALERSHIP WANTS $800 APIECE FOR THESE LED LIGHTS THAT SHOULD LAST MANY, MANY YEARS. A QUICK INTERNET SEARCH REVEALS THAT 1) THE PROBLEM IS WIDESPREAD AND 2) GM WON'T ACKNOWLEDGE IT. WORKING BRAKE LIGHTS ARE A MATTER OF SAFETY, AND THE FACT THAT GM PRODUCES THESE LIGHTS AS CHEAPLY AS POSSIBLE AND THEN CHARGES AN ARM AND A LEG AFTER THE PARTS FAIL EARLY IN THEIR LIFETIME IS SUSPECT TO SAY THE LEAST.

NHTSA ODI 11078513

WIRING ON THE BRAKE LIGHTS IS FAULTY CAUSING THE LIGHT TO WORK ON AND OFF. WHILE DRIVING YOU DON'T KNOW IF YOUR BRAKE LIGHTS ARE WORKING BECAUSE THEY COME ON AND OFF AT TIMES
