BRAKE LIGHT ON VEHICLE WORKS INTERMITTENTLY AND IS NO LONGER SAFE. THIS IS A PROBLEM GMC IS WELL AWARE OF AND NO SOLUTION IN SIGHT. CHEAP METAL BOARD BRAKES INSIDE THE LENS AND LEAVES YOU WITH NO BRAKE LIGHT. I DO NOT WANT MY FAMILY TO BE REAR ENDED BECAUSE OF THIS PROFESSIONAL GRADE? BRAKE LIGHT FAILURE, AT ANY TIME ON ROAD.THIS IS A 2016 GMC YUKON WITH 22710 MILES AS I WRITE. BRAKE LIGHT HAS FAILED WHILE MOVING ON THE CITY STREETS. THIS FAILURE IS CURRENTLY ON THE PASSENGER SIDE BRAKE LIGHT. TRYING TO MAKE APPOINTMENT FOR REPAIR OF THIS PROFESSIONAL GRADE BRAKE LIGHT? BEFORE THE OTHER ONE BRAKES AND PUT MY FAMILY AT RISK OF A ACCIDENT.

MY VEHICLE IS ONLY THREE YEARS OLD. THE RIGHT REAR LED TAILLIGHT HAS FAILED. THE TAILLIGHT NO LONGER WORKS. IT DOES NOT WORK WITH THE DAYTIME RUNNING LIGHTS OR WHEN YOU PRESS ON THE BRAKE. THIS IS A KNOWN ISSUE WITH THE 2016 GMC YUKONS. THE DEALERSHIP WANTS $900.00 TO REPLACE THE ENTIRE LIGHT HOUSING.

NHTSA ODI 11299081

BOTH TAIL LIGHTS AND BREAK LIGHTS HAVE STOPPED WORKING. THEY ARE MORE THAN $700 EACH AND GM KNOWS ABOUT THE PROBLEM AS THEY HAVE NO LIGHTS AVAILABLE, THEY ARE ON BACKORDER FOR WEEKS. YOU CAN FIND A FIX ONLINE BY RESOLDERING A METAL PIECE THAT CAN TEMPORARILY FIX THE PROBLEM.

NHTSA ODI 11299126

MY DRIVER SIDE TAILLIGHT WENT OUT. DEALERSHIP REFUSED TO REPLACE AS MY 2016 WAS NO LONGER UNDER WARRANTY. HOWEVER, THE DEALERSHIP ADMITTED TO THE LARGE NUMBER OF LIGHTS THAT THEY HAVE HAD TO REPLACE. I HAD TO ORDER AND AFTERMARKET LIGHT TO REPLACE MYSELF. THE VERY NEXT DAY AFTER REPLACING THE LIGHT, MY PASSENGER SIDE TAILLIGHT IS NOW OUT. THIS IS UNACCEPTABLE!!! SO MANY COMPLAINTS REGARDING THIS ONLINE. THIS FIRST HAPPENED TO DRIVE SIDE AROUND JULY 2019.WE WERE FINALLY ABLE TO REPLACE THE LIGHT IN JAN 2020. THE PASSENGER TAILLIGHT WENT OUT 1/13/2020.

NHTSA ODI 11299155

MY REAR TAIL LIGHTS STOPPED WORKING AND THE DEALERSHIP IS CHARGING $800 TO REPLACE THE MODULE. PREVIOUSLY I HAD A 2016 YUKON XL AND THE SAME THING HAPPENED AROUND 40K MILES. MY SISTER-IN-LAW ALSO HAS A 2016 YUKON XL AND ONE OF HER TAIL LIGHTS DID THE SAME THING. AFTER SEARCHING ONLINE THIS SEEMS TO BE A COMMON PROBLEM WITH 2015 AND 2016 YUKON XL MODELS AND GM SHOULD BE REPLACING THESE PARTS AT NO COST TO THESE THOUSANDS OF PEOPLE EXPERIENCING THIS PROBLEM WHEN THE CAR ISN'T EVEN 5 YEARS OLD.

RIGHT TAIL LIGHT WENT PUT, TOOK IT TO GET FIXED. THEY SAID IT WAS THE CIRCUIT BOARD AND I HAD TO PAY $900 TO GET IT FIXED. THE DEALERSHIP SAID THEY HAVE HAD A TON OF THE CIRCUIT BOARD REPLACEMENTS AND DIDN'T KNOW WHY GM DIDN'T DO A RECALL. NOW, MY LEFT SIDE CIRCUIT BOARD IS OUT AND NEEDS TO BE REPLACED.

REAR LED TAILLIGHT WENT OUT OUR ONLY 3 YEAR OLD 2016 GMC DENALI. THIS EFFECTS THE STOP, TAIL, AND TURN LIGHTS. THESE LED LIGHTS ARE NOT REPAIRABLE AND THE WHOLE ASSEMBLY HAS TO BE REPLACED. GM CHARGES AN ASTRONOMICAL PRICE OF AROUND $700 FOR EACH SIDE. IT IS VERY HARD TO FIND ANY USED ONES AND ACCORDING TO PART DEALERS GM HAS A 'BOUNTY' ON ANY USED ONES TO TURN BACK IN. OBVIOUSLY GM IS AWARE OF THIS PROBLEM AND NEEDS TO ADDRESS IT AS NOT ONLY AS GOOD CUSTOMER RELATIONS BUT IT'S REALLY A SAFETY ISSUE AS WELL.

LEFT REAR BRAKE LIGHT FAILED IN APRIL, 2019, DEALER ESTIMATE TO REPLACE, $709.86, AFTER SOME HEATED DISCUSSION, "WARRANTY FROM GMC REDUCED THE BILL TO $186. 49,326 MILES WHEN LIGHT REPLACED. 15 SEPTEMBER 2019, MILEAGE 54,290, THE RIGHT BRAKE LIGHT FAILED AND WAS ORDERED BY DEALER, ESTIMATE TO REPAIR $709.86, PART DID NOT COME IN IN 30 DAYS, SO I CALLED GMC TECH ASSIST SERVICE (866-790-5600 AND SPOKE WITH "CHRIS" WHO OPENED A CASE #[XXX]. THIS WAS PASSED TO GMC'S JESSICA AT (866-790-5600 EXT.[XXX]. CONTACTING HER PROVED DIFFICULT AND THE PART STILL DID NOT SHOW UP. FINALLY, ON 18 NOVEMBER, 2019 THE DEALERSHIP CALLED AND SAID THEY HAD THE PART AND INSTALLED IT ON 19 NOVEMBER, 2019, VEHICLE MILAGE NOW 59,061. DEALER CHARGED $418.00. FOR THE LIGHT AND WORK SHOWING A TOTAL COST OF $709.86 AND MY REPAIR COST "COPAY" BEING $418.00 WITH THE GMC WARRANTY SUPPOSEDLY PICKING UP THE DIFFERENCE. TWO MORE ATTEMPTS TO CONTACT "[XXX]", 22 NOV. @ 12:30 P.M., AND 26 NOV. @ 1425 GOT NO RESPONSE. FINALLY CONTACTED HER ON 02 DEC. AND SHE WAS UNAWARE THE PART HAD SHIPPED BUT FOUND THE RECORD AND SAID THAT THE FROM $709.86 TO $418.00 WAS THE ONLY THING THEY COULD DO AND THAT I HAD NO RECOURSE. SHE DID OFFER TO HAVE HER SUPERVISOR CALL ME AND SAID SHE WOULD RECORD MY DISLIKE OF THE SETTLEMENT. SHE COULD NOT OR WOULD NOT ATTEMPT TO EXPLAIN WHY THERE WAS SUCH A HUGE DIFFERENCE IN THE PRICE BETWEEN THE LIGHTS OR THE AMOUNT THAT THE GMC WARRANTY WOULD COVER. LOOKING ONLINE, I NOTE THAT HAVE BEEN MANY THOUSAND OF COMPLAINTS ABOUT THIS FROM THE 2015 THROUGH THE CURRENT 2019 GMC DENALI AND YUKON MODEL VEHICLES. SHOULD GMC NOT PUT OUT A SAFETY RECALL FOR THESE FAILED BRAKE LIGHTS? THERE IS NO INDICATION IN THE DRIVER'S COMPARTMENT THAT THEY ARE OUT. IF NOT POSSIBLE, ARE THEY COVERED UNDER A "LEMON LAW" OR IS THIS JUST ANOTHER CASE OF GMC HAS GOT YOU?

I PURCHASED MY 2016 YUKON XL DENALI USED WITH 40K MILES. I HAVE HAD THE VEHICLE LESS THEN A WEEK AND HAVE HAD SEVERAL PEOPLE TELL ME THAT I HAVE A BRAKE LIGHT OUT ON THE PASSENGER SIDE, BUT EVERY TIME I STOP AND HAVE IT LOOKED AT ITS WORKING JUST FINE. THE COST TO REPLACE IT IS APPROXIMATELY $700 FOR EACH ASSEMBLY. AFTER SOME RESEARCH I HAVE FOUND THAT THERE ARE A LOT OF PEOPLE HAVING THIS ISSUE AND THAT GMC IS AWARE OF THIS ISSUE BUT WON'T DO ANYTHING ABOUT IT. I'M AFRAID THAT I MIGHT BE REAR ENDED BECAUSE THE LIGHTS DECIDE NOT TO WORK AT THAT MOMENT.

TL* THE CONTACT OWNS A 2016 GMC YUKON XL. WHILE THE VEHICLE WAS PARKED, THE CONTACT'S WIFE NOTICED A LEAK ENTERING THE CABIN FROM THE OVERHEAD ANTENNA. THERE WERE NO WARNING INDICATORS ILLUMINATED. ALSO, WHILE PULLING INTO THE DRIVEWAY AND DEPRESSING THE BRAKE PEDAL, THE CONTACT'S NEIGHBOR INFORMED HIM THAT ALL THE REAR BRAKE LIGHTS (REAR DRIVER AND PASSENGER SIDE BRAKE LIGHTS AND TAILGATE BRAKE LIGHT) WERE NOT FUNCTIONING. THE VEHICLE WAS TAKEN TO NORTH COUNTY BUICK GMC (LOCATED AT 1515 AUTO PARK WAY N, ESCONDIDO, CA 92029, (866) 852-7135) WHERE IT WAS DIAGNOSED THAT THE OVERHEAD ANTENNA AND ALL THREE BRAKE LIGHTS NEEDED TO BE REPLACED.

TAIL LIGHT WENT OUT AND IS A KNOWN AND COMMON ISSUE WITHIN 2 TO 4 YEARS OF VEHICLE OWNERSHIP (OFTEN BOTH SIDES GO OUT). IN MY CASE, THE DRIVER SIDE TAIL LIGHT WENT OUT. TOTAL COST FOR ME WAS $850. THERE ARE MANY COMMENTS REGARDING THIS ONLINE. TYPICAL COST TO REPAIR IS $700 TO $800 AT DEALERSHIP. ONLY OTHER OPTION TO REDUCE COST IS TO MAIL OUT PART, BUT THIS LEAVES YOU WITHOUT A VEHICLE FOR SEVERAL DAYS FOR REPAIR AND DELIVERY TIME.

NHTSA ODI 11282467

BRAKE LIGHTS ARE SHORTING OUT CAUSING THEM TO WORK INTERMITTENTLY. CIRCUIT IS BROKEN INSIDE THE SEALED PORTION OF THE LIGHT PREVENTING REPAIR.

THE TAIL LIGHT STOPPED WORKING AND CANNOT CHANGE OUT THE LED BULBS, IT IS A BREAK SOME WHERE THE THE WIRING.

THE TAILIGHT/BRAKE LIGHT KEEP GOING BAD. IT WORKS HALF THE TIME. I WILL CHECK IT AND IT'S WORKING THEN I HIT A BUMP AND PEOPLE TELL ME IT'S NOT WORKING. I HIT ANOTHER BUMP I LOOK AND IT WORKING. AFTER REPLACING IT ONCE ALREADY HAS THE EXACT SAME PROBLEM AND THEY WANT ANOTHER $1000 TO FIX IT BUT THE DEALER TOLD ME GMC NOW HAS A BETTER REPLACEMENT FOR IT. IF THEY HAVE A BETTER BUILT OPTION THEN GMC SHOULD BE MADE TO CHANGE LIGHTS ON ALL OF THEM BEFORE SOME ONE GETS KILLED.

NHTSA ODI 11280471

I WAS NOTIFIED BY ANOTHER DRIVER MY PASSENGER REAR TAIL LIGHT WAS OUT. THERE IS NO NOTIFICATION ON THE DASHBOARD TO ALERT DRIVERS. THE NEXT DAY THE LIGHT WAS WORKING. I CONTINUED TO CHECK IT PERIODICALLY AND FIGURED IT WAS A FLUKE. I WAS STOPPED AGAIN WHILE DRIVING THAT THE LIGHT WAS OUT ROUGHLY A WEEK LATER. AFTER LOOKING INTO REPAIR THE COST IS RIDICULOUS $650-$800+ AND IT APPEARS TO BE A WIDELY KNOWN ISSUE. I WAS ACTUALLY IN A PARKING LOT AND SAW A VEHICLE EXACTLY LIKE MINE SAME LIGHT OUT. NOT SURE WHY LIGHTS ARE GOING OUT IN A THREE YEAR OLD VEHICLE JUST HITTING 40000 MILES.

BOTH LED TAIL LIGHTS STARTED FLICKERING AND FAILED WITHIN A MONTH OF EACH OTHER. THE MECHANIC SAID THIS WAS A KNOWN ISSUE WITH THESE LIGHTS AND THAT THE CIRCUIT BOARD FAILED.

NHTSA ODI 11266851

INTERNAL CIRCUITRY OF PASSENGER TAIL LIGHT CRACKED IN MULTIPLE LOCATIONS CAUSING THE LED'S THAT PROVIDE RUNNING AND STOP FUNCTIONS OF THE LIGHT TO FAIL. THE CAR WAS NOT WRECKED OR DAMAGED IN ANY WAY. APPEARS AS IF METAL FATIGUE FROM BUMPY ROADS PERHAPS CAUSES THE CIRCUITRY TO FAIL AT AT LEAST 2 WEAK POINTS IN THE METAL CIRCUIT. THE PROBLEM WAS POINTED OUT BY A TRAILING POLICEMAN WHILE STOPPED AT A RED LIGHT, HE KINDLY NOTIFIED ME THAT THE ENTIRE LIGHT WAS OUT.

TL* THE CONTACT OWNS A 2016 GMC YUKON. THE CONTACT STATED THAT THE PASSENGER SIDE BRAKE LIGHT FAILED TO ILLUMINATE WHEN THE BRAKE PEDAL WAS DEPRESSED. THE VEHICLE WAS TAKEN TO GREINER BUICK GMC (14555 CIVIC DR, VICTORVILLE, CA 92394, (760) 245-3451) WHERE THE CONTACT WAS INFORMED THAT THE TAIL AND BRAKE LIGHT ASSEMBLIES NEEDED TO BE REPLACED.

MY WIFE WAS DRIVING DOWN A MAJOR ROAD AND A PERSON PULLED NEXT TO HER AT A STOP TO TELL HER THAT HER BRAKE LIGHTS WERE WORKING ONLY PART OF THE TIME. GM HAD JUST SERVICED MY VEHICLE AND DIDN'T CATCH IT, AND UPON RESEARCHING THE ISSUE, IT IS A KNOWN FAULTY DESIGN OF THE TAIL LIGHT ASSEMBLY. THE LED BRAKE LIGHT STARTS INTERMITTENTLY FAILING AT THE 2 YEAR POINT, LEADING TO DRIVERS FOLLOWING DRIVERS TO NOT KNOW THAT THE LEADING VEHICLE IS STOPPING. THIS IS A COMMON ISSUE AND THE ONLY RESPONSE FROM GM IS TO MAKE THE CUSTOMER BUY A NEW $700 BRAKE LIGHT ASSEMBLY. THE ISSUE IS SO COMMON THAT MULTIPLE COMPANIES HAVE STARTED BRAKE LIGHT REPAIR SERVICES AND MULTIPLE YOUTUBE VIDEOS EXIST TO WALK INDIVIDUALS THROUGH THE PROCESS OF REPAIRING THEIR OWN BRAKE LIGHTS. THE COST OF THE REPAIR IS SO STEEP THAT I HESITATE TO GET THE PROBLEM FIXED, AND THOUGH GM REPORTEDLY HAS DEVELOPED A REPLACEMENT LIGHT ASSEMBLY THAT CORRECTS THE FAULT, THEY ARE NOT TAKING RESPONSIBILITY FOR THE DEFECTIVE BRAKE LIGHT ASSEMBLE THAT THESE VEHICLES COME OFF THE ASSEMBLY LINE WITH. THE MAJOR DANGER IS THAT WE DRIVE FROM THE FRONT OF THE VEHICLE AND LIKELY DO NOT KNOW OUR BRAKE LIGHTS ARE INTERMITTENTLY FAILING--SINCE GM CANNOT EVEN CATCH THIS WHEN THEY DO SERVICE ON VEHICLES (MINE HAD BEEN IN THE SHOP FOR AN OIL CHANGE A FEW WEEKS BEFORE THE BRAKE ISSUE), THEN THEY ARE LEAVING A LOT OF CUSTOMERS DRIVING WITHOUT BRAKE LIGHTS TO AVOID THE COST OF THE REPAIR EVEN THOUGH THEY APPROVED A FAULTY DESIGN.
