The contact owns a 2015 GMC Yukon XL. The contact stated that while his wife was driving at an undisclosed speed, the contact stated he was following behind in another vehicle and noticed that the taillights were out.

The brake lights intermittently come on and off. Not reliable and the entire assembly has to be replaced per light in order to work. Sometimes if you hit a bump it will work for a bit then go back out. They have been removed, cleaned, but there is no way to fix them without replacing them. This is a known problem with GMC and they will not warranty or recall this issue.

This is a common issue that is not being resolved by GM. First one, now BOTH of my rear tail lights are malfunctioning due to manufacturing defects. This is a well publicized problem and I feel that GM should be responsible for continuing to ignore the issue. Replacement tail lights are approximately $750 each. There are many businesses that have sprung up solely to repair these tail lights.

Tail lights are very inconsistent of working or not working. Sometimes they work but most times they don't.

I received a letter from GMC dated December 2019 warning of brake lights intermittenly not illuminating. I have periodically checked the lights for failure over the last 3 years. On September 8, 2022, a motorist pulled beside me and informed me that my brake lights were not working. I confirmed that the lights were not working and called GMC regarding the letter I had received in 2019 and was told that a recall had not been issued and that my vehicle was outside the 6 year eligibility period. This defect is Extremely Dangerous to myself and others due to the inherent unpredicability and unreliabilty of an important safety necessity, i.e., knowing that others will see that I am stopping/slowing down. I believe that due to the intermittent nature of the failure of a highly necessary safety feature, GMC should issue a recall to repair at no cost ALL vehicles.

Tail light failure with no ability to change out bulb. Entire assembly must be changed which costs nearly $1000.

I have had to replace both front and rear exterior lighting in past (3). Now my rear brake light is now out. This makes 3 exterior that I’ve had to complete replace. Went out suddenly. No way to replace bulbs, dealer reports Entire assembly needs replacing at cost of almost $1000. There has to be a design flaw that every exterior lighting has gone out for so many owners and has to be REPLACED. There should be a recall on this. This model has had so many costly issues.

Both taillights and brake lights have gone out within 4 months of each other.

Brake lights - left brake light works intermittently, and often does not work. 3rd brake light (top center) has quit working. Both are issues with cracks in the circuit board, which googling has shown to be a known issue. Faulty, poorly designed or constructed parts!

Breaks are faulty, lights continue to go out in the rear after only a year after purchase. I’ve read other complaints about these issues. could be wiring or electrical issue with the breaks. Engine sounds like a plane is about to take off, has had starting problems. Overall horrible vehicle. There are a lot of problems with the vehicle, the lights are extremely dangerous as person behind would not know if I’m stopping when they fail to work and can cause a serious accident. Engine is a major concern as well.

Driver side brake lights don't work again. This will be the 3rd time that I know of that this piece of equipment has been changed out.

LED Brake Lights fail due to design error typically on both side of the vehicle. I have found multiple reports of a failure on a circuit board that was poorly designed. A copper tracing is very narrow and fractures due to vibration resulting in Brake Light failure. Because the entire module must be replaced the repair costs $800-$900 per side.

Tail lights are not functioning properly. N182180270 was issued due to very common issue but no recall. The special adjustment only covers up to 72,000 miles. I now have 106,000 so not covered? Serious safety issue if brake lights are malfunctioning and GM aware of issue. If technician checking lights and they are intermittently working, then I drive away from dealer and they intermittently no longer work, that is a serious safety issue and a recall should happen. I took my vehicle in for an oil change and on the drive to have serviced I was told by my wife driving behind me that the right rear brake light wasn’t working. I asked tech to check. Technician confirmed but states left isn’t working either. Yet on drive to drop the vehicle for oil change the left was working. And we have a time stamped photo as proof(attached). I had someone tell me right rear brake light was out a couple of years ago but when I had it checked, all were on. So when are they working? When are they not working? And that is why a recall should be issued. correct a faulty design. These aren’t an easy fix of replacing a bulb. The whole unit has to be replaced at $700+ each. How many people are out there driving with these intermittent brake lights? We periodically check our lights to ensure working. But if these lights are on/off intermittently, that does very little good. Scary!

THE CONTACT OWNS A 2015 GMC YUKON XL. THE CONTACT STATED THAT WHILE DRIVING AT AN UNDISCLOSED SPEED, THE CONTACT WAS ALERTED BY HER HUSBAND WHO WAS DRIVING BEHIND THE VEHICLE, THAT THE REAR TAIL LIGHTS WERE INOPERABLE. THE CONTACT WAS ALSO ALERTED BY OTHER DRIVERS THAT THE REAR TAIL LIGHTS WERE NOT FUNCTIONING AS NEEDED. THE VEHICLE WAS TAKEN TO SIERRA BLANCA MOTOR CO. (304 US-70, RUIDOSO, NM 88345, (855) 707-6474) TO BE REPAIRED UNDER NHTSA CAMPAIGN NUMBER: 19V645000 (SERVICE BRAKES, HYDRAULIC). THE TECHNICIAN ALSO INSPECTED THE LIGHTS AND STATED IN THE DIAGNOSTIC REPORT THAT ALL LIGHTS WERE WORKING AT THE TIME OF INSPECTION. THE VEHICLE WAS TAKEN TO AN UNKNOWN DEALER FOR THE FAILURE HOWEVER, THE SECOND DEALER WAS UNABLE TO DUPLICATE THE FAILURE. THE CONTACT THEN HAD HER FRIEND, WHO WAS A RETIRED AUTHORIZED GMC TECHNICIAN, INSPECTED THE TAILLIGHTS AND DUPLICATED THE FAILURE. THE VEHICLE WAS THEN TAKEN BACK TO SIERRA BLANCA MOTOR CO. HOWEVER, THE SERVICE ADVISOR INSPECTED THE TAIL LIGHTS BUT OFFERED NO ASSISTANCE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT THEY WOULD CHECK WITH THE DEALER TO SEE IF THEY COULD ASSIST WITH THE FAILURE. THE MANUFACTURER LATER INFORMED THE CONTACT THAT THEY WOULD OFFER A 25% DISCOUNT FOR EACH LIGHT TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 61,835.

REAR BRAKE/TAILLIGHT ASSEMBLY NOT WORKING CONSISTENTLY IN MOTION.

Mileage: 107,000

LEFT REAR LIGHT ASSEMBLY INTERMITTENT OPEN CIRCUIT. WIRING CHECKS OKAY. GOOD POWER AND GROUNDS. NOTED THAT THE LAMP HOUSING HAS EVIDENCE OF CORROSION AT THE BASE OF THE MAIN CONNECTOR. THE HOUSING IS A SEALED UNIT (NO SERVICEABLE PARTS) SO THE NATURE ASSEMBLY NEEDS TO BE REPLACED. I AM A 37+YEAR A.S.E. MASTER TECHNICIAN AND STATE OF MICHIGAN MASTER TECHNICIAN SO I AM WELL SEASONED AT PROPER AUTO/LIGHT TRUCK ELECTRICAL DIAGNOSIS. THE LIGHT WILL GO OUT WHILE SITING STILL AND/OR IN MOTION. THIS IS A SAFETY CONCERN FOR OBVIOUS REASONS.

Mileage: 106,201

ONE OF THE BREAK LIGHTS IS OUT. THEY HAVE MADE THE BRAKE LIGHTS IN SUCH A WAY THAT YOU CAN NO LONGER JUST REPLACE THE BULBS BUT HAVE TO REPLACE THE ENTIRE UNIT AT A COST OF $885. THERE IS A DESIGN FLAW IN THE 2015 AND 2016 MODELS THAT CAUSES THE BRAKE LIGHTS TO FAIL. GMC IS AWARE OF IT AND DID EXTEND WARRANTY COVERAGE SO THAT IF YOU ARE "LUCKY" ENOUGH TO HAVE THEM FAIL WITH LESS THAN 72,000 ON YOUR VEHICLE THEY WILL REPLACE THEM AT NO COST BUT AFTER THAT THEY WILL NOT. THEY KNOW THE PRODUCT AND IT SHOULD BE RECALLED. IT IS A SAFETY ISSUE FOR PEOPLE TO DRIVE AROUND WITHOUT BRAKE LIGHTS BECAUSE IT COSTS NEARLY $900 A PIECE TO REPLACE THEM! PERHAPS THEY SHOULDN'T HAVE TURNED WHAT USED TO BE AN CHEAP, EASY THING TO FIX ON YOUR OWN INTO A $900 REPAIR IN THE FIRST PLACE. NOW THAT THEY HAVE THEY SHOULD AT LEAST STAND BEHIND THE PRODUCT.

LED BRAKE LAMP WENT OUT AT 42K MILES, BUT GM REQUIRES REPLACEMENT OF ENTIRE TAIL LAMP ASSEMBLY AT EXPONENTIAL COST.

Mileage: 42,000

THE LEFT LED TAIL LIGHT WOULD GO OUT AND THEN COME BACK ON. THIS HAS BEEN HAPPENING FOR OVER A YEAR NOW. POLICE STOPPED ME TWICE BUT THANKFULLY, DID NOT GIVE ME A TICKET. HAD IT REPAIRED 2 OR 3 TIMES. IT MIGHT LAST A DAY OR TWO AND THEN GOES OUT AGAIN. APPARENTLY, THERE IS A THIN METAL PIECE THAT IS SORTED TOGETHER THAT KEEPS BREAKING. THE RIGHT ONE HAS STARTED DOING IT TOO. I WAS OVER THE MILEAGE FOR THE RECALL. CAN'T AFFORD THE $1600 OR SO IT WOULD COST FOR NEW IMPROVED TAIL LIGHTS. WHAT DOES MILEAGE HAVE TO DO WITH REPAIRING A DEFECT IN THE PRODUCTS USED IN THE TAIL LIGHT? I AM CONSTANTLY AFRAID SOMEONE WILL REAR END ME SINCE THE LIGHT DOESN'T WORK.

2015 REAR BRAKE LIGHTS WORK INTERMITTENTLY AND NEED TO BE REPLACED OR REPAIRED. GMC KNOW THERE ARE NUMEROUS COMPLAINTS ABOUT THIS PROBLEM AND HAVE DONE NOTHING. HUGE SAFETY ISSUE!!

TOOK MY CERTIFIED PRE-OWNED 2015 YUKON XL INTO DEALER WHILE STILL UNDER WARRANTY WITH INTERMITTENT FAILURE IN BOTH TAIL LAMPS (THE RED PART FOR BRAKE AND TAIL LAMP FUNCTION GOES OUT; TURN SIGNAL STILL WORKS). CONDITION WAS NOT NOTED ON MY SERVICE TICKET SINCE THE TAIL LAMPS WAS WORKING FINE AT THE TIME. WARRANTY EXPIRED, PASSENGER TAIL LAMP WENT OUT COMPLETELY AND BOTH DEALER AND A CALL TO GMC TOLD ME THAT THEY WOULDN'T ASSIST IN SPITE OF MY ATTEMPT TO ADDRESS WHILE UNDER WARRANTY. NEEDED TAIL LAMP TO PASS STATE INSPECTION AND RETURN MY WIFE AND FOUR KIDS SAFELY TO THE ROAD, SO I HAD TO PAY. AS I WALKED OUT OF THE DEALERSHIP TO RETRIEVE MY VEHICLE AFTER THE $400 PASSENGER TAIL LAMP REPLACEMENT, I FOUND THE DRIVER SIDE TAIL LAMP TO BE INOPERABLE, EVEN THOUGH IT HAD JUST PASSED THE STATE INSPECTION 20 MIN PRIOR. I SHOWED THE SERVICE ADVISOR AND SPOKE TO SERVICE MANAGER. THEY BOTH AGREED THAT THE TAIL LAMP ISSUE IS WIDE-SPREAD, UNSAFE, AND A MAJOR QUALITY ISSUE, BUT THEY WERE BOUND BY GMC POLICIES. YES, GMC EXTENDED THE WARRANTY FOR THESE TAIL LAMPS, BUT I BOUGHT MY VEHICLE AS PREOWNED CERTIFIED WITH 68K MILES. SPECIAL PART WARRANTY WENT TO 70K AND MY CERTIFIED WARRANTY WENT TO 80K. I DID MY PART AND TOOK THE VEHICLE IN AS SOON AS THE PROBLEM AROSE, YET HERE I AM HOLDING AN $800 BAG OF BROKEN TAIL LAMPS. HORRENDOUS QUALITY ISSUE THAT IS A MAJOR SAFETY ISSUE FOR THESE VEHICLES. IT IS TIME TO ISSUE THE RECALL!!!

Mileage: 85,000

MAJOR SAFETY ISSUES WITH THIS VEHICLE. ANOTHER 2015 YUKON WITH NO TAIL OR STOP LIGHTS. I'M OVER MILLAGE ON SPECIAL RECALL. THERE SHOULD BE NO TIME/MILLAGE ISSUE ON THIS. SEAT BELTS LOCK UP. BRAKES ARE EITHER GOOD OR MUSSY WHENEVER THEY WANT TO BE. HARD TO STOP THE VEHICLE. ALSO WHEN I FIRST PURCHASED THE VEHICLE IT WOULD COMPLETELY DIE (NO LIGHTS MOTOR DIED, NO POWER STEERING, NO AIR BAGS, NO RADIO NOTHING AT ALL ON THE X-WAY AT 70 MPH) AND THE DEALER COULD NOT REPAIR IT! RUST ON FRAME RAILS. (AND MORE).

Mileage: 72,000

THE REAR PASSENGER & DRIVER SIDE BRAKE LIGHTS JUST RANDOMLY STOPPED WORKING. NOT A BULB ISSUE AS IT IS THE LED PANEL OF LIGHTS. THE BACK-UP BULB STILL WORKS, BUT THE LED BRAKE LIGHTS DON'T. LED LIGHTS SHOULD LAST YEARS. DEALERSHIP SAYS IT HAPPENS A LOT TO THESE VEHICLES, AND I HAVE TO BUY A WHOLE NEW UNIT FOR EACH SIDE. THIS IS A HUGE SAFETY ISSUE - BREAK LIGHTS FAILING DUE TO POOR WIRING. AGAIN NOT A REPLACEABLE BULB ISSUE, IT IS DUE TO A WIRING ISSUE WITHIN THE LED LIGHTING UNIT ITSELF.

Mileage: 80,000

MY PASSENGER SIDE TAIL LIGHT ASSEMBLY NEED TO BE REPLACED AS THE BRAKE LIGHTS ARE NOT WORKING. THIS HAS BECOME A COMMON PROBLEM AS EVIDENCED BY THE NUMBER OF COMPLAINTS FILED ON YOUR SITE FOR THE SAME ISSUE. LACK OF PROPERLY FUNCTIONING TAIL LIGHTS IS A MAJOR SAFETY CONCERN AND A RECALL SHOULD BE ISSUED. *TR

TL* THE CONTACT OWNS A 2015 GMC YUKON XL. THE CONTACT STATED THAT WHILE DEPRESSING THE BRAKE PEDAL THE REAR BRAKE TAILLIGHTS FAILED TO ILLUMINATE. THE VEHICLE WAS TAKEN TO KEWEENAW BUICK GMC LOCATED AT 608 QUINCY ST, HANCOCK, MI 49930, TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE REAR BRAKE LIGHTS WERE DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE, BUT PROVIDED NO ASSISTANCE. THE FAILURE MILEAGE WAS 102,000.

WE PURCHASED THIS VEHICLE IN FEBRUARY 2019. LESS THAN A YEAR LATER OUR RIGHT TAIL LIGHT STARTED GOING OUT RANDOMLY. THEN IT COMPLETELY WOULD NOT WORK. WE PAY FOR AN EXTENDED WARRANTY, BUT IT DIDN'T COVER IT. THEN SHORTLY AFTER THE LEFT TAIL LIGHT DID THE SAME THING. WE CURRENTLY HAVE 84K MILES ON OUR VEHICLE. DUE TO NEGLIGENCE, AND A DISHONEST COMPANY (GMC), THIS MILITARY FAMILY IS DOWN TO 1 VEHICLE AS WE CANNOT AFFORD THE ALMOST $2K IT WILL COST TO FIX THE TAIL LIGHTS. THIS IS NOT DUE TO ANYTHING WE DID, IT HAS EVERYTHING TO DO WITH FAULT BRAKE LIGHTS THAT GMC WILL NOT FIX PAST 72K MILES WHICH IS DISGUSTING AND A SLAP IN THE FACE TO PEOPLE WHO GIVE THEM THEIR HARD EARNED MONEY. I HAVE DONE EXTENSIVE RESEARCH AND THIS IS A VERY COMMON PROBLEM IN THESE VEHICLES. THERE ARE DOZENS OF BLOGS, POSTS, WEBSITES, ETC OF CUSTOMERS COMPLAINING OF THIS ISSUE AND GMC NOT HELPING PAST 72K MILES WHICH IS A HORRIBLE EXPLANATION AND IS NOT HELPFUL TO MOST OF US. WE HAVE ALREADY HAD TO PAY OUT OF POCKET FOR THINGS THAT HAVE BROKEN (NORMAL WEAR AND TEAR WHICH IS UNDERSTANDABLE) THAT WASN'T COVERED UNDER OUR PLATINUM EXTENDED WARRANTY. HOWEVER, GMC NEEDS TO DO THE RIGHT THING ESPECIALLY FOR OUR MEN AND WOMEN IN UNIFORM, AND FIX WHAT THEIR COMPANY HAS DEEMED AS FAULTY PAST 72K MILES!!! *TR

BRAKE LIGHTS INTERMITTENTLY NOT ILLUMINATING AND GOING OUT. BOTH DRIVER AND PASSENGER BRAKE LIGHTS. *TR

THE BRAKE LIGHT IS NOT WORKING. ALL OTHER FUNCTIONS IN THE ASSEMBLY ARE FINE. REVERSE AND TURN SIGNAL, NO BRAKE INDICATION. IT DOES NOT ACTIVATE A WARNING ON THE DASH FOR THE BRAKE LIGHT FAILURE. THIS HAPPENS 24/7... THIS SHOULD NOT OCCUR WITH AN ITEM PRICED AT OVER $700.00 TO REPLACE. *TR

BREAK LIGHT INTERMITTENTLY ILLUMINATES ON DRIVER'S SIDE. RECEIVED LETTER FROM GMC DATED DECEMBER 2019, "INTENDED TO MAKE YOU AWARE THAT SOME 2015 MODEL YEAR GMC YUKON XL VEHICLES MAY HAVE A CONDITION WHERE THE BRAKE LIGHTS INTERMITTENTLY DO NOT ILLUMINATE". THE WOULD REPAIR IT WITH NO COST ONLY IF THIS WOULD HAVE OCCURRED WITHIN 6 YEAR OF THE DATE YOUR VEHICLE WAS ORIGINALLY PLACED IN SERVICE OR 72,000 MILES. OF COURSE, WE ARE WAY ABOVE THAT. DEALER QUOTED $800 COST REPAIR.

Mileage: 82,000

BOTH TAIL LIGHTS (BRAKE LIGHTS AND RUNNING LIGHTS IN RED) STOP WORKING WITH NO WARNING TO THE DRIVER. THIRD BRAKE LIGHT DOES CONTINUE TO WORK. THIS IS NOTICED WHEN PARKED AND WHEN IN MOTION. THIS IS A SAFETY ISSUE FOR OTHER DRIVERS CRASHING INTO OUR VEHICLE BECAUSE THEY DO NOT KNOW THAT WE ARE BRAKING. A FRIEND HAD TO POINT THIS OUT TO US IN THE SCHOOL PICKUP LINE. FIRST NOTICED ON 2/13/20. HAD TO BUY TWO NEW TAILLIGHT ASSEMBLIES AND INSTALL.

Mileage: 111,575

NO BRAKE LIGHT IN BOTH REAR LIGHTING ASSEMBLIES. STARTED WITH THE PASSENGER SIDE AND NOW THE DRIVERS SIDE. GMC ISSUED A LETTER IN DECEMBER 2019 STATING THEY'D PAY FOR REPAIRS IF VEHICLE IS LESS THAN 6 YEARS OR 75,000 MILES WHICH EVER COMES FIRST. WE'LL I'M OVER ON BOTH. GMPP EXTENDED WARRANTY DOESN'T COVER THIS REPAIR. SPEND $75K FOR THIS TRUCK AND NOW THIS.

Mileage: 85,000

BOTH TAIL LIGHTS STOPPED WORKING ON THE FREEWAY DURING MY TRIP TO SAN DIEGO FROM PHOENIX. ABOUT HALFWAY HERE ONE TAIL LIGHT WENT OUT IN ABOUT 20 MILES LATER THE OTHER ONE STOPPED WORKING. I KNOW THIS BECAUSE A FRIEND WAS FOLLOWING ME.I CALLED THE DEALERSHIP, HE STATED THAT THE TAIL LIGHTS ARE ON NATIONAL BACKORDER AND WON'T BE IN FOR A WEEK PLUS. NOW I AM DRIVING AROUND CALIFORNIA WITH NO BRAKE LIGHTS.. I ONLY HAVE 48,000 MILES ON THIS SUV, EACH TAIL LIGHT IS $760 THE ONLY WAY TO REPAIR THIS IS TO REPLACE THEM.

THE CONTACT EXITED THE VEHICLE AND CONFIRMED THAT THE TAILLAMPS WERE INOPERABLE. THERE WAS NO WARNING LIGHTS ILLUMINATED. THE VEHICLE WAS TAKEN TO GUNN BUICK GMC LOCATED AT (16440 INTERSTATE 35 FRONTAGE RD, SELMA, TX 78154 (866) 468-6484) TO BE DIAGNOSED.

GMC RECENTLY ADVISED US THAT THE TAILGATE LIGHTS HAVE HAD PROBLEMS WHERE THEY "INTERMITTENTLY" DO NOT ILLUMINATE. WE HAVE HAD THIS ISSUE FOR QUITE SOMETIME WHERE DRIVERS CANNOT SEE OUR TAILGATE LIGHTS WHEN THE PROBLEM OCCURS. BECAUSE IT HAS BEEN INTERMITTENT, IT HAS BEEN VERY HARD FOR THE SHOP TO DIAGNOSE AS WHEN THEY GET IT AND IT IS ON, THEY CAN'T FIGURE OUT WHAT IS WRONG WITH IT. SINCE WE RECEIVED THE LETTER FROM GMC, WE HAVE BEEN INTO THE DEALERSHIP TO GET IT RESOLVED, BUT THEY WILL NOT DO IT BECAUSE OUR MILES ARE OVER. I HAVE TOLD THEM THAT THEY KNOW ITS AN ISSUE AND THAT IT IS INTERMITTENT AND WHEN PEOPLE TAKE IT INTO THE SHOP TO GET IT DIAGNOSE, ITS A HIT AND MISS. I HAVE NOW SEEN OVER A DOZEN OTHER GMC'S ON THE ROAD WITH THE SAME ISSUE. LAST WEEK, WHILE TRAVELING WITH KIDS TO A SOCCER TOURNAMENT, BOTH WEREN'T WORKING AT NIGHT AND WE WERE PULLED OVER. I FORTUNATELY HAD THE LETTER IN THE CAR AND SHOWED IT TO HIM. HE GAVE ME A WARNING AND ADVISED THAT IT IS VERY DIFFICULT FOR CARS TO SEE AT NIGHT WHEN THERE ARE NO TAILGATES ON AND THAT GMC HAD BETTER GET THIS RESOLVED. I HAVE MADE TWO REQUESTS WITH GMC AND THEY HAVE DENIED THE REQUEST. I EVEN TOLD THEM THAT I WOULD COST SHARE IF WE MEET IN THE MIDDLE AND THEY WOULD NOT. THEY KNOW THIS IS AN ISSUE, YET THEY AREN'T WILLING TO EXTEND THE WARRANTY OR MAKE IT A RECALL. THIS IS VERY DANGEROUS AND COULD CAUSE A LOT OF ACCIDENTS WITH GMC MODELS NATIONWIDE. I HOPE THAT THIS IS BROUGHT TO SOMEONE'S ATTENTION AND THAT GMC IS ENCOURAGED TO GET THIS RESOLVED WITH 2015 YUKON XL SUVS AND THAT WE AND MANY OTHERS ARE ABLE TO GET THEIR TAILGATES REPLACED.

THE BRAKE AND TAIL LIGHTS ON THIS GMC YUKON ONLY RANDOMLY LIGHT UP. HAVE BEEN TOLD RANDOM TIMES BY OTHER MOTORIST THAT BRAKE OR TAIL LIGHTS ARE NOT WORKING ON HIGHWAY. I'VE CONTACTED GM MULTIPLE TIMES ON PHONE AND AT DEALER AND THEY WANT ME TO PAY OUT OF POCKET TO FIX THIS SAFETY ISSUE. THEY FINALLY SENT A LETTER OUT TODAY NOTING THERE AWARE OF THIS PROBLEM BUT STILL WANT FIX MINE BECAUSE IT'S OVER 72K ON YUKON. SAFETY HAS NO MILEAGE LIMIT AND GM NEEDS TO FIX THESE PROBLEMS.

WE PURCHASED A 2015 GMC YUKON XL DENALI IN JULY 2019 FROM JACKIE COOPER IN EDMOND, OK. IN DECEMBER 2019, WE NOTICED THAT THE BRAKE LIGHTS STARTED INTERMITTENTLY GOING OUT. SOME DAYS THEY WORK FINE, AND THEN THE NEXT DAY THEY DON'T WORK AT ALL. WE'VE EVEN HAD PEOPLE STOP US AND TELL US THAT THE BRAKE LIGHTS WERE "FLICKERING". THIS IS OBVIOUSLY A SAFETY CONCERN, AND WITH THE EXTRAORDINARY COST TO REPLACE ONE OF THESE LIGHTS, IT'S A BUDGETARY CONCERN, AS WELL. SINCE WE STARTED NOTICING IT, WE ALSO HAVE HEARD OF OTHER OWNERS OF THIS SAME MODEL AND YEAR THAT HAVE HAD THE SAME ISSUE. THIS CERTAINLY SEEMS LIKE A DEFECTED PRODUCT WHICH NEEDS A BETTER SOLUTION. PLEASE TELL ME THERE IS ANOTHER SOLUTION BESIDES SPENDING $1,000-$1,500 TO REPLACE SOMETHING THAT USED TO BE A SIMPLE BULB I COULD FIND AT A AUTO PARTS STORE.

DRIVER SIDE TAIL LIGHT STOPPED WORKING. BRAKE LIGHT.

Mileage: 91,000

OWNED THE CAR FOR 2 YEARS, BEEN IN THE SHOP THREE TIMES FOR THE SAME ISSUE, CAR JERKS GOING LESS THAN 25 MPH AND WHILE DRIVING AND ACCELERATING. BOTH TAIL LIGHTS ARE LED AND INOPERABLE.

I HAVE A 2015 YUKON DENALI XL WITH 53K MILES.A COUPLE OF MONTHS AGO ONE BAKE/TAILLIGHT STARTING FLICKERING. IT WOULD WORK AT TIMES AND THEN NOT AT ALL OTHER TIMES. LAST WEEK, BOTH OF THE BAKE/TAILLIGHTS WENT COMPLETELY OUT! I HAVE NO LIGHTS IN THE REAR OF MY VEHICLE. I WAS PULLED OVER TWICE IN ONE WEEKEND FOR THIS!! I WAS DRIVING DOWN THE HIGHWAY AT NIGHT WITH MY CHILDREN IN THE VEHICLE NOT KNOWING THAT BOTH OF MY LIGHTS WERE NOW NOT WORKING! IT DOESN'T SEEM THAT THEY ARE BURNT OUT BECAUSE IT I MESS WITH THEM FROM THE OUTSIDE, THEY WILL FLICKER A LITTLE BIT. OF COURSE FACTORY WARRANTY IS EXPIRED AND NEW LIGHTS ARE AT LEAST $800 A PIECE!!

Mileage: 25,000

BOTH LEFT AND RIGHT REAR TAIL LIGHTS STOPPED WORKING. THEY FIRST STOPPED ONLY INTERMITTENTLY BUT THEN COMPLETELY WENT OUT, WITHIN ONLY 3-4 YEARS OF NEW. RESEARCH SHOWS THIS PROBLEM IS EXTREMELY COMMON AND REPRESENTS EITHER, AT BEST, A VERY POOR DEFECT IN MANUFACTURING OR, AT WORST, A PLANNED-IN DEFECT IN ORDER TO STEAL MONEY FROM CONSUMERS WHO ALREADY PAID HANDSOMELY FOR A VEHICLE. SINCE THE LED HOUSING IS A SINGLE SEALED UNIT, DEALERS STATE THE ENTIRE LIGHT HOUSING NEEDS TO BE REPLACED AT AN APPROXIMATE COST OF $700 PER LIGHT. WHILE IT'S TRUE THAT LIGHTS CAN 'GO OUT', A CONTINUED FAILURE OF THE SAME PART (RESEARCH SHOWS THE EXACT SAME FAILURE POINT CAN BE FOUND IN EACH CIRCUMSTANCE) SHOULD REPRESENT GROSS NEGLIGENCE IN MANUFACTURING WHICH ONLY A RECALL NOTICE CAN SATISFY.

Mileage: 75,000

PASSENGER BREAK LIGHT WORKS INCONSISTENTLY

THE REAR LIGHT WENT OUT. IT CANNOT BE FIXED WITH THE CHANGE OF A BULB. THE ENTIRE PIECE HAS TO BE REPLACED BECAUSE IT IS AN ELECTRICAL ISSUE. AFTER LOOKING ONLINE AND TALKING TO OTHERS WITH THE SAME MAKE AND MODEL, THIS IS A COMMON ISSUE WITH THIS MAKE/MODEL THAT NEEDS TO BE ADDRESSED AND GMC HELD ACCOUNTABLE.

PASSENGER SIDE LED TAIL LIGHT STOPPED WORKING. SAW THAT THIS PROBLEM HAS BEEN REPORTED ON NHTSA MANY TIMES (OVER 400) BUT THERE HAS NEVER BEEN A RECALL. TO FIX THE TAIL LIGHT THE ENTIRE FIXTURE HAD TO BE REPLACED AT DEALER FOR A COST OF $900 WHICH IS RIDICULOUS. THIS IS A DEFINITE SAFETY HAZARD AS THERE WAS NO INDICATOR TO TELL ME THAT THE TAIL LIGHT AND BRAKE LIGHT WERE OUT! ONLY FOUND OUT ABOUT THE PROBLEM WHEN A FRIEND WAS FOLLOWING ME HOME AND TOLD ME ABOUT IT. SURPRISED THAT THERE HAS BEEN NEITHER A VOLUNTARY RECALL BY GM OR A MANDATED RECALL BY THE NHTSA. DEFINITELY NEEDS ADDRESSING. ALSO, THIS PROBLEM HAS BEEN REPORTED ON 2015-2017 YUKONS SO THERE APPEARS TO BE EITHER A DEFECTIVE PART OR BAD DESIGN.

PASSENGER SIDE TAIL LIGHT HAS BEEN GOING OUT INTERMITTENTLY FOR MONTHS. SINCE THE PROBLEM BEGAN I'VE BEEN HAVING BATTERY ISSUES AND NOW BATTERY AND LIGHT ARE COMPLETELY DEAD. DEALER SAID IT WOULD BE $800 FOR LIGHT. THERE WAS NO INDICATOR/SENSOR THAT SHOWED THE LIGHT WAS OUT. I FOUND OUT BY ANOTHER DRIVER WHO PULLED UP NEXT TO ME AND TOLD ME. DRIVING AROUND I'VE SEEN MANY VEHICLES (SAME MODEL) WITH THE SAME ISSUE. THIS IS A SAFETY HAZARD, BECAUSE UNLESS SOMEONE TELLS US WE DON'T KNOW THE LIGHT IS OUT AND THEY ARE PREMATURELY GOING OUT. THE COST IS RIDICULOUS! THIS IS MY SECOND GMC AND I DID NOT HAVE ANY PROBLEMS LIKE THIS BEFORE. THIS IS THE CAR I DRIVE MY CHILDREN AROUND IN! IT IS APPARENT THAT IT IS A MANUFACTURER ISSUE. GMC NEEDS TO DO RIGHT BY ITS CUSTOMERS, BEFORE SOMEONE GETS HURT!

TAIL LIGHT ON 2015 GMC YUKON XL BROKE ON 7/18/19. AUTHORIZED GM DEALERSHIP QUOTED $902.57 PARTS AND LABOR TO REPLACE. I COMPLAINED THE PRICE IS TOO HIGH AND THERE IS A DESIGN FLAW WITH THE TAIL LIGHT IF IT COSTS THAT MUCH TO REPLACE. LED LIGHTS ARE SUPPOSED TO LAST LONGER. THERE SHOULD BE A RECALL FOR THE TAIL LIGHT. FILED A FORMAL WRITTEN COMPLAINT WITH GMC CUSTOMER SERVICE ON 7/22/19. PURCHASED 2 NEW TAIL LIGHTS ONLINE FROM CARID.COM FOR $495.00 AND INSTALLED THE NEW TAIL LIGHTS MYSELF. GMC FINALLY REPLIED ON 7/31/19 MY CLAIM IS DENIED BECAUSE I INSTALLED THE REPLACEMENT TAIL LIGHTS MYSELF AND DID NOT HAVE THE DEALERSHIP INSTALL. GMC ADVISED IF THE DEALERSHIP INSTALLED THEN THEY WOULD HAVE REFUNDED ME $495.00. WHAT DIFFERENCE DOES IT MAKE WHO INSTALLED THE NEW REPLACEMENT LIGHT? DRIVING AROUND WITH A BROKEN TAIL LIGHT IS A SAFETY ISSUE AND ALSO AGAINST THE LAW AND I HAD TO MAKE A QUICK DECISION WHILE IT TOOK GMC 9 DAYS TO REPLY AND IT WAS BY PHONE - STILL DO NOT HAVE WRITTEN CONFIRMATION. GMC CUSTOMER SERVICE HAVE A STRANGE PROCEDURE WHEREBY YOU HAVE TO HAVE AN APPOINTMENT TO SPEAK TO A CUSTOMER SERVICE REP. WHAT IF YOU HAVE SCHEDULED A BUSINESS TRIP OR HAVE TO ATTEND A MEETING? I HAVE SENT A WRITTEN APPEAL TO GMC PROTESTING THEIR DENIAL DECISION AND AT THE TIME OF WRITING HAVE NOT RECEIVED A REPLY. BOTTOM LINE IS THAT DUE TO SAFETY ISSUE AND IT'S CAUSE FOR A TRAFFIC CITATION THERE SHOULD BE A RECALL.

MY YUKON 2015 HAD 62,000 MILES IN MAY 2019 WHEN THE LEFT TAIL LIGHT WENT OUT. BECAUSE IT IS AN LED LIGHT, THE PART FROM THE DEALERSHIP AVERAGE AROUND $700. IT WAS NO LONGER UNDER WARRANTY AND I HAD IT REPLACED IN THE BEGINNING OF JUNE 2019. TODAY MY RIGHT REAR TAIL LIGHT IS NOW OUT. APPARENTLY THIS IS A KNOWN PROBLEM WITH THE 2015 YUKONS AND GMC WILL NOT ISSUE A RECALL OR DO ANYTHING ABOUT IT. THE PART IS WAY OVERPRICED. IF THIS IS AN ISSUE, IT SHOULD EITHER BE RECALLED FOR SAFETY REASONS OR THE PART SHOULD BE MADE AVAILABLE AT A MORE REASONABLE PRICE. SPENDING $1500.00 FOR BREAKLIGHTS IN ONE MONTH IS WRONG.

MY VEHICLE IS A 2015 YUKON XL. IN 2018 I HAD TO REPLACE MY FRONT DRIVER SIDE LED LIGHTS AND MY PASSENGER SIDE REAR BRAKE LIGHT FOR A COST OVER $2,000. I LITERALLY HAD TO CANCEL A FAMILY VACATION IN ORDER TO PAY FOR THE LIGHTS ON MY VEHICLE. IT IS ILLEGAL TO DRIVE WITHOUT WORKING BRAKE LIGHTS. THIS YEAR, JUNE 2019, I NEEDED TO REPLACE THE DRIVER SIDE BREAK LIGHT AT A COST CLOSE TO $1,000.

THE HEADLIGHTS HOUSINGS HAVE CONDENSATION IN THEM AND IT HAS CAUSE THE TURN SIGNAL AND LED LIGHTS TO SHORT OUT. THE LED LIGHTS IN THE TAIL LIGHT HOUSING INCLUDING THE BRAKE LIGHTS HAVE ALSO SHORTED OUT. THE LED SCREEN AND COMPUTER IN THE CENTER CONSOLE HAS ALSO SHORTED OUT.

DRIVER SIDE TAIL LIGHT WOULD INTERMITTENTLY GO IN AND OUT FROM WORKING AND NOT WORKING. THE TAIL LIGHT WOULD DO THIS WHILE IN MOTION, WHILE STATIONARY, IT DID NOT MATTER. THE LOCAL DEALERSHIP THAT WE BOUGHT IT FROM SAID WE WOULD NEED TO REPLACE IT. OVER $750. NOW THE PASSENGER SIDE TAIL LIGHT IS DOING THE EXACT SAME THING. HUGE SAFETY HAZARD. CLEARLY A FAULTY PART, NOT JUST A BULB GOING OUT, BUT THE ENTIRE ELECTRICAL DESIGN OF THE THE TAIL LIGHT IS FLAWED. GM CHARGES YOU TO REPLACE THE ENTIRE HOUSING WITH THE SAME EXACT FAULTY PART THAT WAS ON THERE BEFORE.

THE ENTIRE REAR LIGHT COMPONENT (BRAKE LIGHT, RUNNING LIGHTS, TURN SIGNAL) NEEDS TO BE REPLACED TO REPAIR THIS. THE COST TO REPLACE IS ~$500.

MY PASSENGER BRAKE LIGHT INTERMITTENTLY DOES NOT WORK. THIS IS CLEARLY A COMMON PROBLEM WITH THIS MAKE AND MODEL. HERE IS AN EXAMPLE OF ONE OF MANY FORUMS : HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-T53845_DS768963 THIS IS A SAFETY PROBLEM AND GMC SHOULD OFFER A RECALL FOR THEIR FAULTY LED LIGHTS.

THIS IS THE SECOND COMPLAINT THAT I HAVE MADE TO NHTSA. THE FIRST TIME, THE VEHICLE WAS SPONTANEOUSLY TURNING OFF AND SHUTTING DOWN DURING BACKING IN AND TURNS CAUSING A SAFETY ISSUE. THIS RESULTED IN A RECALL, AND A "SOFTWARE UPDATE" THAT WAS DONE TWICE TO CORRECT THE ISSUE. RIGHT AND BACK PASSENGER LIGHTS BEGAN TO BLINK ON AND OFF AND WATER GETS INTO THE BRAKE LIGHT. THE DEALER TOLD ME THIS WAS M ISSUE. THIS TIME THE 4WD SERVICE LIGHT CAME AND THE CAR APPEARED TO BE STUCK IN "4WD LOW" MAKING IT "DRAG" AT A REDUCED SPEED WHEN DRIVING. ALSO, THE "SERVICE TRAILER BRAKE" LIGHT CAME ON REPEATEDLY. I HAVE NEVER USED THE TRAILER BRAKE. I TOOK IT INTO AN AUTHORIZED DEALER, SELLERS GMC IN FARMINGTON HILLS, MI. THEY TOLD ME I NEEDED A NEW "MODULE", SO I PAID TO HAVE THAT DONE. WITHIN ONE DAY THE SAME SERVICE LIGHTS CAME ON AGAIN. "SERVICE 4 WD" AND "SERVICE TRAILER BRAKE." I IMMEDIATELY TOOK THE VEHICLE BACK AND AM NOW BEING TOLD IT NEEDS ANOTHER SOFTWARE UPDATE AND A NEW TRAILER BRAKE TRANSFER SWITCH. QUITE FRANKLY, I BELIEVE THAT THIS MODEL HAS SIGNIFICANT, UNADDRESSED COMPUTER SOFTWARE ISSUES AND THE DEALER DOES NOT KNOW WHO TO FIX IT. THE CAR IS UNSAFE BECAUSE IT SPONTANEOUSLY STOPS WORKING APPROPRIATELY DURING DRIVING. THE CONCERNS HAVE BEEN VARIOUS AND ALWAYS SEEM TO AFFECT STEERING, WHEN TURNING OR BACKING IN. I AM BEING CHARGED FOR VARIOUS CONTROL PANELS AND MODULES. I AM REQUESTING THAT THIS CONCERN GETS ADDRESSED BEFORE THERE IS A SERIOUS INJURY. I WOULD LIKE MY VEHICLE FIXED AND RETURNED TO A SAFE CONDITION. I WAS NEVER TOLD UPON PURCHASE, THAT THIS MODEL WOULD REQUIRE SO MANY "SOFTWARE" UPDATES TO REMAIN SAFE. THIS SHOULD NOT BE A BURDEN PLACED ON A CONSUMER FOR A VEHICLE TO OPERATE SAFELY. THIS IS DANGEROUS.

MY WIFE AND I HAVE OWNED GMC VEHICLES ALL OUR LIVES AND HAVE NEVER BEEN MORE DISSATISFIED WITH THE LACK OF QUALITY DESIGN IN THE REAR TAIL LIGHT LED DESIGN AND DESIGN LIFE. IN CONDUCTING RESEARCH THE LAST FEW DAYS, THIS HAS BEEN A CONSISTENT AND WELL DOCUMENTED DESIGN FLAW THAT GM STILL HAS NOT ADDRESSED. LED LIGHTING WHEN DESIGN PROPERLY IS SUPPOSED TO FUNCTION PROPERLY MUCH LONGER THAN STANDARD BULB INCANDESCENT LIGHTING. THIS CREATES A SAFETY ISSUE WITH OUR VEHICLE BECAUSE WE HAVE NO REAR LIGHTING AND THEN WE RECEIVE THE ESTIMATE FROM OUR DEALER "ROYAL BUICK GMC" AT OVER $1500. OBVIOUSLY, I AM FEELING SUCH FRUSTRATION BECAUSE MY REAR TAIL LIGHT ASSEMBLY'S ARE NOT FUNCTIONING PROPERLY ON MY WIFE'S **** GMC YUKON XL SLT. OF COURSE AFTER THE INITIAL WARRANTY HAS EXPIRED.

THERE IS A KNOWN ELECTRICAL ISSUE WITH THE YUKON TAIL LIGHTS. THE ENCLOSED LED RUNNING LIGHTS AND BRAKE LIGHTS WILL GO OUT AND NOT OPERATE. THIS IS A HUGE SAFETY CONCERN AS THERE IS NO BRAKE LIGHT THAT WILL ILLUMINATE AND NO RUNNING LIGHT. BOTH OF MY TAIL LIGHTS HAVE GONE OUT ON MY VEHICLE. DURING A RECORD CHECK I HAVE LEARNED THAT THIS IS A COMMON PROBLEM WITH THE YUKON'S. GMC HAS FAILED TO TAKE ACTION ABOUT THE KNOWN PROBLEM. THE PROBLEM IS PERSISTENT WHILE BEING STOPPED AND DRIVING. SECONDLY THE BRAKING VACUUM SYSTEM WILL GO OUT UNEXPECTEDLY. THIS CAUSES THE ASSISTED BRAKES TO FAIL CAUSING THE BRAKING SYSTEM NOT TO TAKE AFFECT AND STOP THE VEHICLE PROPERLY. THIS IS A HUGE SAFETY CONCERN AS YOU WILL NOT BE ABLE TO SAFELY STOP YOUR VEHICLE IN A TIMELY MANNER AND WILL CAUSE SEVERAL ACCIDENTS. I NOTICED THAT THE BRAKES HAD FILLED WHILE BEING STOPPED AT A STOPLIGHT AND ALSO WHILE BEING MOBILE AND DRIVING.

THE ELECTRICAL BOARD ASSOCIATED WITH IT HAS ISSUES THE MECHANIC STATED. I REVIEWED MANY POST ONLINE AND WONDER WHY THIS ISN'T A REQUIRED RECALL.

MY PASSENGER FRONT LIGHT COVER IS ACQUIRING CONDENSATION WHICH MAKES THE LIGHTS GO OFF AND ON, AND MY DRIVER SIDE BRAKE LIGHT WORKS ONLY INTERMITTENTLY. MY INSURANCE OR WARRANTY WON'T COVER ANYTHING TO FIX THESE LIGHT ISSUES. THESE ISSUES STARTED ABOUT MAY 2018. WE WEREN'T IN A WRECK OR SUSTAINED ANY DAMAGES THAT WOULD HAVE LED TO THESE ISSUES. I HAVE TALKED TO TWO OTHER OWNERS OF THE SAME MAKE/MODEL/YEAR VEHICLE AND WE ALL HAVE SAFETY ISSUES THAT ARE NOT BEING RESOLVED BY GM VWARRANTIES. I WANT TO SEE GM ISSUE RECALLS AND ACCEPT COMPLETE FINANCIAL RESPONSIBILITY FOR REPAIRS. I WOULD ALSO LIKE TO SEE THE REAR LIGHTING SYSTEM REDESIGNED SO THE COMPONENTS ARE NOT DEPENDENT ON EACH OTHER. MY BRAKE LIGHT WENT OUT AND INSTEAD OF BEING ABLE TO REPLACE A BULB THE ENTIRE UNIT HAS TO BE REPLACED AT $1700.00 THAT WE JUST SIMPLY DO NOT HAVE.

BRAKE LIGHTS WORK INTERMITTENTLY. THE PROBLEM IS NOT WITH THE LED BUT WITH THE POOR QUALITY OF THE CONTROLLER BOARD. BOTH OF MY TAIL LIGHTS HAVE ENCOUNTERED THIS ISSUE IN THE LAST 4 MONTHS AND THEY ARE VERY EXPENSIVE TO REPLACE. THE PART ALONE IS OVER $ 900.00. I HAVE TALKED TO A COUPLE OF DEALERS ABOUT THIS AND THEY ARE A FREQUENT PROBLEM, AND ONE DEALER SPECIFIED THAT HE HAS SOLD 4 REPLACEMENT UNITS IN THE LAST 24 HOURS. THIS INDICATES THAT THE TAIL LIGHT ASSEMBLY IS VERY POOR QUALITY AND CAN BE A SAFETY HAZARD AS THERE IS NO WAY TO TELL THAT YOUR BRAKE LIGHT ISN'T WORKING UNLESS SOMEONE TELLS YOU.

BAD LED BRAKE LIGHTS: WE PURCHASED OUR GMC YUKON XL 2015 IN MAY 2016. SINCE THEN WE HAVE HAD TO REPLACE BOTH BRAKE LIGHTS(1 AFTER A YEAR-MARCH 2017 AND THE 2ND AFTER 2 YEARS-AUG 2018) AND HAVE HAD THE VEHICLE ONLY 2 YEARS. THEY ARE LED LIGHTS SO NOT A CHEAP REPAIR. QUOTED COST $750-$2000. SO FAR, OUR WARRANTY HAS COVERED THE REPAIRS BUT ONCE WARRANTY IS OFF, IT WILL COST TOO MUCH TO REPAIR AND IS NOT SAFE TO DRIVE WITHOUT REPAIRING! WE HAVE HAD MANY VEHICLES OVER THE YEARS AND HAVE ONLY REPLACED BRAKE LIGHTS 2-3 TIMES AND FOR LESS THAN $25 EACH TIME. THIS APPEARS TO BE A BAD DESIGN OR FAULTY PARTS BY GMC. ONE OF THE FAILURES WAS DUE TO INTERNAL SHORT IN THE LED MODULE. WE WOULD LIKE GMC TO RESOLVE THE FAULTY PARTS AND RECALL THE PART AND FULLY REPLACE OUR BRAKE LIGHTS WITH RELIABLE LIGHTS VS LIGHTS THAT ONLY LAST A YEAR. THANK YOU!
