2016 GMC YUKON XL Exterior Lighting Problems

The OEM LED taillights can fail due to a manufacturing deficiency. A metal strip that connects the LED's to the cars taillight circuit develops a crack and interrupts current flow to the taillight LED's. The above is common knowledge to the car community and is searchable on line. Concerns: 1) If both taillights are failed at the same time the vehicle doesn't have any of the required visible markings, especially at night. 2) From an economic point of view, unlike vehicles that use incandescent light bulbs that are easily replaced when burnt out, these LED light assemblies have to be completely replaced to the cost of several hundred dollars plus labor which could/will lead to the neglecting of this repair because of the economics. 3) Unlike incandescent bulbs, LED's are should last much longer to the point of outlasting the life of the vehicle. This isn't the case when there is a manufacturing defect. In my case on 10/21/21 the defective taillight assemblies was replace under a defective taillight extended warranty agreement. I requested to have both replaced because of the odds of the second one failing. They refused. So when the opposite side assembly failed recently i was out of the extended warrant date resulting in a cost to me of $392.88 labor included. In conclusion, The well documented failure of the above taillight assemblies leads to vehicles being non conforming to FMVSS.

There is a special policy to replace faulty tail lamps. However, the policy is only extended through 72,000 miles or 5 years which is ridiculous, and should be a recall. I had my drivers side tail lamp replaced in February 2022 because it was not working. I wasn’t aware of the mileage and year restrictions at that time. Fast forward to today, I have my passenger side tail lamp intermittently working. Now out of the specific time frame, I’m left to encounter this expense out of my own pocket. Clearly GM is aware of the problem, but has not issued a recall on the tail lamp issue. It’s not just a burned out brake light, but apparently an electrical issue with the way they were initially wired. This is a very dangerous situation, as I have no idea if and when my brake light is out. God forbid if they were to go out and I were to be rear ended due to GMs lack of taking responsibility.

The taillights, which included both the brake lights and running lights, quit working or only worked intermittently. Safety was put at risk because anytime we drove the vehicle in the dark (which is often!) the rear of the vehicle could not be seen, and the brake lights would not be activated when braking would occur, either day or night. This made us more likely to be in an accident, in my opinion, though thankfully we were not. Our regular mechanic did confirm that the lights were only working only intermittently, thought he did not have a solution but for replacing them, which would cost $800 a piece. There was no warning for this problem, the issue first appeared a year ago and we've been dealing with it since. I was finally able to purchase remanufactured taillights.

r rear taillight and brake light does not work and no indicator light to warn me. Do not know how long its been out. Afraid to drive. Had it checked and found special policy n182180270 . I contacted dealer and they said it would be $69.00 to just verify issue. contacted manufacture and was told it was out of coverage by less than 100 days. The vehicle has less than 40,000 miles and stays in garage. Case # 9-8269822 they said it had to be inspected by dealer that is a 40 mile round trip though traffic with no brake light , not safe especially when the instructions on the policy states just to turn light on and verify if it works ,if not replace unit.

The contact owns a 2016 GMC Yukon XL. The contact stated while driving 75 MPH with her husband driving behind her, he noticed that the taillights were inoperable. The vehicle was taken to an independent mechanic and the contact was informed that the taillight functions were inoperable. The contact was informed that the failure experienced was similar to the Special Coverage under N182180270. The vehicle was not repaired. The dealer was contacted and informed the contact that the vehicle was out of coverage. The manufacturer was contacted and the contact was informed that the vehicle was out of warranty. The failure mileage was 32,022.

Mileage: 32,022

My issue pertains to a known problem. The driver's side tail light has failed. GM issued Special Coverage Adjustment N182180270 because of this issue where the part was covered for up to 6 years or 72k miles. Mine failed after 6 years and 4 or 5 months at 66k miles. It's utterly ridiculous that a defective, $800 light is fine to break after 6 years with no warranty assistance.

The driver’s side brake light assembly failure of no brake light when brake is applied. It can be inspected upon request. This may cause another driver to not notice intentions to stop or slowdown and cause an accident. This problem is constant. It has not been inspected. No warnings of the failure has been displayed.

Last month the passenger tail light stopped working. We took it out not realizing that you have to replace the entire unit. So we put the tail light back in and it magically started working again. Then yesterday the driver's side tail light stopped working, so we did the same. Took it out, waited and put it back (since we know we can't just run to the store and get a new one), except this time it didn't start working. I know there's a recall on the tail lights but I can't seem to find anyone to help me. The vehicle is only 6 years old and the tail lights at $800 each, should last a lot longer than that!

Both brake/tail lights intermittently not functioning.

LED tail light unit continues to crack (metal inside) and not work. Each replacement is over $500. You have to replace or you’ll be ticketed because it is a safety hazard. It is not a bulb replacement it is a faulty design that is costing people thousands to fix and it’s not right. GMC is aware of this defect and they aren’t doing anything about it. Please help and recall these taillights to be replaced by the updated lights!! Thank you for your time and consideration.

The brake light LED panel stopped working on one side and goes out intermittently in the other side

GM issues a specials service campaign N182180270 Tail lights Inoperative, goes to 72000 miles the subject vehicle has 75000. Both rear tail brake lights do not work and the third brake light.

My 2016 Yukon Denali passenger brake light has stopped working. I see there are many other complaints identifying the same issue - question why hasn't GMC issued a recall for a known problem. With the circuit board breaking this is obviously a manufacturing issue that needs to be addressed and is most definitely a safety issue and increases the odds of being rear-ended as a result of inoperative brake lights. Fortunately I had a stranger stop me in a store parking lot to let me know the brake light was out. The repair is $800 at the dealer!

The contact owns a 2016 GMC Yukon XL. The contact stated that the passenger’s side taillight was inoperable. The contact took the vehicle to the dealer and was informed that the failure was related to NHTSA Campaign Number: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control) however, the VIN was not included. The vehicle was not repaired. The manufacturer was not made aware of the issue. The approximate failure mileage was 59,000

Mileage: 59,000

THIRD TIME THE LED CIRCUIT BOARD LED LIGHTS ON REAR TAIL LIGHT ASSEMBLY HAS SHORTED OUT AND REQUIRED REPLACEMENT DUE TO BRAKE LIGHTS NOT WORKING. GMC IS WELL AWARE THAT THIS IS A FREQUENT ISSUE ON THE YUKONS AND HAS DONE NOTHING ABOUT IT. INDIVIDUAL BRAKELIGHT CIRCUIT BOARD OF LED BULBS CANNOT BE CHANGED OUT BECAUSE IT IS PLASTIC WELDED AND SEALED INTO THE TAIL LIGHT, COSTING $600.00 TO REPAIR EACH TIME IT SHORTS OUT. THIS IS A SAFETY ISSUE THAT SHOULD NOT KEEP HAPPENING. THERE ARE FOLKS DRIVING W/O FUNCTIONAL BRAKELIGHTS BECAUSE THEY CANNOT AFFORD THE COST AND FREQUENCY IF REPAIR. IT IS A POORLY MADE ENGINEERING FLAW BY GM THAT DEALER ADMITS HAPPENS ALL THE TIME DUE TO MOISTURE GETTING INTO LIGHT AND SHORTING CIRCUIT BOARD. BRAKELIGHT WILL NOT WORK WHEN STATIONARY OR WHEN IN ANY MOTION.

Mileage: 30,000

TL* THE CONTACT OWNS A 2016 GMC YUKON XL. THE CONTACT STATED WHILE DRIVING AT VARIOUS SPEEDS, THE PASSENGER'S SIDE REAR BRAKE LIGHT FAILED TO ILLUMINATE. THERE WERE NO WARNING LIGHTS ILLUMINATED. THE VEHICLE WAS TAKEN TO PATRIOT BUICK GMC HYUNDAI (2001 SE WASHINGTON BLVD, BARTLESVILLE, OK 74006, (918) 347-4045) AND THE CONTACT WAS INFORMED THAT THE VEHICLE FAILED TO MEET THE MILEAGE QUALIFICATION FOR THE SATISFACTION PROGRAM. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS CONTACTED HOWEVER, NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS 88,000.

Mileage: 88,000

BOTH SIDES BRAKE LIGHTS STOP WORKING INTERMITTENTLY THEN COME BACK ON AGAIN. *TR

Mileage: 40,027

PASSENGER SIDE REAR BRAKE LIGHT WORKING INTERMITTENTLY. TAKEN TO DEALER TWICE FOR ISSUE AND WAS WORKING WHEN DEALER CHECKED IT. 90,000 MILES ON VEHICLE SO WELL OUT OF WARRANTY. DROVE HOME FROM DEALER... STOPPED WORKING ON WAY HOME. STARTED WORKING NEXT DAY. PART IS $600-800 FOR SOMETHING THAT IS CLEARLY A MANUFACTURER DEFECT. I DON'T CONSIDER A CIRCUIT BOARD THAT CRACKS IN THE SAME PLACE ON MANY SAME MODEL VEHICLES (AS PER INTERNET FORUMS) TO BE "NORMAL WEAR AND TEAR". GM WON'T DO ANYTHING ABOUT IT. THIS IS CLEARLY A SAFETY ISSUE. BRAKE LIGHT IS A SERIES OF LEDS ON A THINLY PRINTED CIRCUIT BOARD. *TR

Mileage: 90,000

REAR TAIL LIGHTS (BRAKE LIGHTS) WORK INTERMITTENTLY. THERE IS A "SPECIAL COVERAGE ADJUSTMENT" BUT IT IS SET FOR A MAXIMUM NUMBER OF MILES OR TIME (6-YEARS). I HAVE A 2016 GMC YUKON XL. THE PASSENGER'S SIDE WAS REPLACED IN 2018 AND NOW THE DRIVER'S SIDE IS DEFECTIVE/INOPERABLE. BUT BECAUSE WE ARE AT 96000 THEY WON'T REPAIR. *TR

Mileage: 96,000

RIGHT REAR TAIL LIGHT / BRAKE LIGHT QUIT WORKING. VEHICLE HAS 74,200 MILES. WHOLE TAIL LIGHT ASSEMBLY HAS TO BE REPLACED. THIS IS A $800 DOLLAR REPAIR FOR A DEFECTIVE PART THAT GM KNOWS IS DEFECTIVE AND A SAFETY ISSUE. HOW IS IT A VEHICLE MANUFACTURER CAN SELL A VEHICLE WITH A DEFECTIVE PART? THIS IS A SEALED PART THAT THE OWNER CANNOT REPAIR ON THEIR OWN. THIS ISSUE IS NOT DUE TO OWNER NEGLECT OR MISUSE BUT MANUFACTURER'S DEFECT. *TR

Mileage: 74,200

MY BRAKE LIGHTS WILL WORK ONE MINUTE AND GO OUT THE NEXT. I HAD A FRIEND AND MY HUSBAND TELL ME THAT WHEN THEY WERE FOLLOWING ME THE LIGHT WAS OUT WHEN I STOPPED BUT AT THE NEXT STOP OR AT HOME IT WOULD WORK. THIS HAS BEEN HAPPENING FOR MONTHS. LAST WEEK I TOOK IT FOR STATE INSPECTION AND THE INSPECTOR SAID IT WAS OUT I HAD TO GET IT REPLACED. WHEN I PULLED FORWARD IT STARTED WORKING AGAIN TO PASS INSPECTION. TODAY I TOOK MY YUKON TO THE DEALERSHIP FOR AN OIL CHANGE AND IT WENT OUT AGAIN. OTHERS WAITING TOLD ME THIS IS A RECALL ON OTHER YEAR/MODELS WITH GMC. THERE IS A SHORT IN THE CIRCUIT PANEL.

MY CAR HAS 60,000 MI ON A 2016. THE REAR BRAKE LIGHT WENT OUT ON PASSENGER SIDE AND I AM BEING TOLD BY DEALER I HAVE TO REPLACE THE COMPLETE ASSEMBLY- NOT JUST A BULB. ESTIMATED COST IS $800.00 FOR ONE SIDE. IN RESEARCHING I HAVE FOUND THIS ISSUE IS NOT UNCOMMON. THIS IS RIDICULOUS FOR WHAT SHOULD BE THE COST OF A BULB.

Mileage: 60,000

I HAVE BEEN NOTIFIED ON TWO OCCASIONS ON THE ROAD THAT MY TAIL LIGHT WAS OUT. WHEN I WAS ABLE TO CHECK THEM, BOTH TAIL LIGHTS LIT UP THEN TURNED ON. IT MUST BE AN INTERMITTENT ISSUE.

Mileage: 29,500

LEFT AND RIGHT BRAKE/RUNNING LIGHTS WORK INTERMITTENTLY. OCCASIONALLY ONE SIDE WILL WORK AND THE OTHER DOESN'T AND VISE VERSA. MORE OFTEN THAN NOT, NEITHER SIDE WORKS. GM KNOWS ABOUT THIS DEFECT AND REFUSES TO CORRECT THE PROBLEM THAT THEIR MANUFACTURING CAUSED. THIS IS A MAJOR SAFETY CONCERN AS MY WIFE AND THREE YOUNG CHILDREN USE THIS VEHICLE ON A DAILY BASIS.

TL* THE CONTACT OWNS A 2016 GMC YUKON XL. THE CONTACT STATED THAT WHILE STOPPED AT A TRAFFIC LIGHT, THE CONTACT WAS INFORMED THAT THE BRAKE LIGHTS WERE INOPERABLE. THE VEHICLE WAS TAKEN TO TEXAN GMC BUICK LOCATED AT 18225 EASTEX FWY, HUMBLE, TX 77338, (281) 973-3117, TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT BRAKE LAMP BULBS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER HAD BEEN INFORMED OF FAILURE. THE FAILURE MILEAGE WAS 92,000.

Mileage: 92,000

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.

Mileage: 49,000

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.

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.

Mileage: 80,000

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.

Mileage: 40,000

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.

Mileage: 100,000

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.

Mileage: 41,000

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. THE CONTACT STATED THAT THE REAR DRIVER'S SIDE BRAKE LIGHT AND ANTENNA WERE REPAIRED, BUT THE OTHER BRAKE LIGHTS WERE STILL NOT REPAIRED. THE MANUFACTURER WAS INFORMED OF THE FAILURES. THE FAILURE MILEAGE WAS 61,000.

Mileage: 61,000

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.

Mileage: 64,000

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.

Mileage: 86,000

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.

Mileage: 40,000

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.

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.

THE PASSENGER SIDE BRAKE LIGHT STOPPED WORKING WITH NO INDICATION ON THE INSTRUMENT PANEL. THIS APPEARS TO BE A COMMON PROBLEM FOR MODEL YEARS 2015 THRU 2019 DUE TO A DESIGN/MANUFACTURING DEFECT. THE REPAIR INVOLVES REPLACING THE ENTIRE TAILLIGHT ASSEMBLY FOR ABOUT $800. THE DEALER WILL NOT REPAIR UNDER WARRANTY AFTER 2 YEARS OR 24,000 MILES EVEN THOUGH IT IS A SAFETY RELATED DEFECT. THERE IS NOT A SAFETY RECALL AT THE PRESENT TIME. MY VEHICLE IS OVER 2 YEARS OLD BUT ONLY HAS 20,000 MILES.

A FEW MONTHS AGO THE DRIVER SIDE TAILLIGHT STOPPED WORKING (OR WOULD ONLY WORK INTERMITTENTLY). TOOK TO DEALER AND THEY SAID IT WAS $850 TO REPAIR. FILED COMPLAINT WITH GMC AND AS I WAS WORKING THROUGH THAT WITH THEM THE PASSENGER SIDE TAILLIGHT STOPPED WORKING AS WELL. NOW I HAVE A VEHICLE THAT IS NOT EVEN 3 YEARS OLD WITHOUT WORKING TAILLIGHTS. THIS IS TOTALLY RIDICULOUS. A $65,000 'PROFESSIONAL GRADE' VEHICLE SHOULD NOT BE HAVING THIS ISSUE AT 55,000 MILES. GMC NEEDS TO WAKE UP AND RECALL THESE. WILL IT TAKE A FATAL ACCIDENT TO SPUR A RECALL??

THIS CARS REAR PASSENGER BRAKE LIGHT NO LONGER WORKS! THE SERVICE MANAGER AT THE GMC DEALERSHIP SAYS THEY HAVE TO REPLACE A GREAT DEAL OF THESE IN CARS NOT VERY OLD LIKE MINE. THIS IS DEFINITELY A SAFETY ISSUE FOR BRAKE LIGHTS TO BE GOING OUT ON A 3 YEAR OLD CAR! IT HAS BEEN OUT FOR MONTHS AND I WAS JUST PROCRASTINATING BECAUSE YOU MUST GO TO A DEALERSHIP SHOP TO GET IT REPLACED. YOU CANNOT GET IT AT A PART STORE YOURSELF SO MY CAR PROBABLY ONLY HAD 20,000-21,000 MILES ON IT WHEN THIS STARTED.

REAR LED BRAKE LIGHTS NO LONGER LIGHT UP.

Mileage: 59,000

FAULTY BREAK LIGHTS. THE LED CIRCUIT IS FAULTY AND CRACKS WHICH REQUIRES THE ENTIRE LIGHT ASSEMBLY TO BE REPLACED.

Mileage: 52,000

I HAVE BEEN TOLD BY MULTIPLE PEOPLE THAT ONE OR BOTH OF MY BRAKE LIGHTS HAS NOT BEEN WORKING. I HAVE TESTED THEM MYSELF AND I TOO GET MIXED RESULTS. SOMETIMES ONE WORKS AND OTHER TIMES NEITHER. BEING THAT I DRIVE 30 MINUTES TO AND FROM WORK EVERYDAY THIS IS A MAJOR CONCERN.

Mileage: 50,000

VEHICLE HAS 52,000 MILES ON IT AND DRIVER SIDE TAIL LIGHT STOPPED WORKING. IT IS AN LED AND SHOULD LAST FOR MANY YEARS. HAS NOT BEEN IN AN ACCIDENT. THIS IS FAULTY MANUFACTURING. CONSUMER PROTECTION NEEDED.

Mileage: 52,530

REAR BRAKE LIGHT WORKS INTERMITTENTLY.

REAR TAIL LIGHT / BRAKE LIGHT QUIT WORKING WHILE STILL UNDER WARRANTY. WE TOOK IT TO THE DEALER AND WAS DENIED COVERED. THE UNIT IS A COMPLETE LED ASSEMBLY AND CANNOT BE REPAIRED. THE PRICE QUOTED WAS $700 FOR THE ASSEMBLY. A QUICK INTERNET SEARCH SHOWS THAT THOUSANDS OF PEOPLE HAVE EXPERIENCED THE SAME ISSUE AND GM WILL NOT ACKNOWLEDGE IT AS A PROBLEM AND WILL NOT COVER UNDER WARRANTY. THIS IS MOST DEFINITELY A DANGEROUS SITUATION FOR OWNERS WHO SUDDENLY HAVE NO TAIL OR BRAKE LIGHTS ON THEIR NEW/NEWER VEHICLES.

Mileage: 40,000

THE BACK MASSAGER TAIL LIGHT HAS STOPPED WORKING. AFTER MUCH RESEARCH THIS SEEMS TO BE A PROBLEM WITH THE VEHICLE. TO REPLACE THE LIGHT (ONE LIGHT), I WAS QUOTED $750.

Mileage: 51,000

TAIL LIGHT ISSUES. REPLACED DRIVER SIDE LIGHT APPROXIMATELY LESS THEN 6 MONTHS AGO AND PASSENGER TAIL LIGHT IS OUT. SAME ISSUES AS DRIVER SIDE LIGHT.

REAR PASSENGER BRAKE LIGHT STOP WORKING, VEHICLE IS ONLY 2 YEARS OLD. WE SHOULD NOT BE HAVING THIS ISSUE SO SOON OR AT ALL, SINCE LED LIGHTS NORMALLY DONT STOP WORKING. I ALSO LOOKED INTO FIXING IT AND ITS GONNA COST $700 DOLLARS. THIS IS RIDICULOUS!

PROGRESSIVE INTERMITTENT BRAKE LIGHT FUNCTIONALITY THAT EVENTUALLY CULMINATED WITH COMPLETE INOPERABILITY; ONLY THE RIGHT/LEFT BRAKE LIGHT ASSEMBLIES ARE AFFECTED; REVERSE LAMPS OPERATE; UPPER CENTER BRAKE LIGHT FUNCTIONS NORMALLY; THIS IS A KNOWN PROBLEM WITH GMC BRAKE LIGHT ASSEMBLIES PER MULTIPLE FORUMS

DRIVERSIDE TAIL LIGHT INTERMITTENTLY STOPS WORKING. CAR MILAGE IS IN THE 40,000'S. DIAGNOSTIC TEST AT DEALERSHIP WHERE PURCHASED CONFIRMS " DRIVER REAR TAIL LIGHT SHORTED OUT INTERNALLY. RECOMMEND REPLACING DRIVER TAIL LIGHT. RECOMMEND TAIL LIGHT ASSEMBLY $899" . MY SISTER HAS A YUKON XL DENALI 2016 AND HAS THE SIMILAR ISSUE BUT BOTH OF HER TAIL LIGHTS INTERMITTENTLY STOP WORKING POSING A HUGE SAFETY CONCERN. DRIVING IN MY AREA I SEE MANY NEWER YUKON XL WITH THE DRIVER SIDE TAIL LIGHT OUT. LIGHTING IS NOT COVERED UNDER EXTENDED WARRANTY AND COST TO FIX IS EXTREMELY EXPENSIVE, WHICH COULD MAKE THE AVERAGE DRIVER PUT OFF THE LARGE EXPENSE. THE TAIL LIGHT INTERMITTANTLY STOPS WORKING WHILE THE CAR IS ON, DOES NOT MAKE A DIFFERENCE IF THE CAR IS STATIONARY OR IN MOTION. SERVICE REP AT DEALERSHIP STATED THIS PROBLEM IS "COMMON".

GMC BRAKE LIGHT FAILURE - I OWN A 2016 GMC YUKON XL AND AFTER ABOUT 45,000 MILES THE BRAKE LIGHTS HAVE STARTED INTERMITTENTLY NOT WORKING. AFTER HAVING A GMC TECHNICIAN TELL ME THAT ITS A KNOWN ISSUE AND SEEING HUNDREDS OF OTHERS POSTS ONLINE, IT IS EVIDENT THAT THIS IS A VERY WIDESPREAD PROBLEM. I WAS NEARLY INVOLVED IN A REAR END CRASH ON THE FREEWAY BECAUSE THE DRIVER TOLD ME I DID NOT HAVE ANY BRAKE LIGHTS. THIS IS A SERIOUS SAFETY ISSUE AND GMC NEEDS TO CORRECT IT. THEY WANT ME TO PURCHASE 2 REPLACEMENT LIGHT UNITS AT 750.00 EACH.

BOTH BREAK LIGHTS WENT OUT, WEATHER HAS BEEN HOT IN THE HIGH 90S WHICH GMC DEALER EXPRESSED COMMON CONCERN AMONG OWNERS DURING SUMMER. VEHICLE IS USED 15MILES/DAY ON AVERAGE.
