LEFT BACK TAILLIGHT DEFECTIVE. IT WAS REPLACED BY GMC IN 2017 UNDER WARRANTY (BELOW 36,000 MILES) NOW AT 44000 IT FAILED AGAIN. LOTS AND LOTS OF PEOPLE POSTING THE SAME ISSUE ONLINE. BAD DESIGN OR JUST PLAIN BAD QUALITY. SEE ONE OF THE POSTS HERE: HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-T53845_DS768963 SEE VIDEO HERE EXPLAINING ISSUE ON HOW INTERNAL BOARD CRACKS AND CAUSES THE ISSUE: HTTPS://WWW.YOUTUBE.COM/WATCH?V=NNLDJPYMDZC ANOTHER VIDEO: HTTPS://WWW.YOUTUBE.COM/WATCH?V=2LJXUQME3TU DEALER CHARGES $844 PARTS AND LABOR TO REPLACE, THIS IS A KNOWN ISSUE FOR GMC, THIS NEEDS TO BE A RECALL. THE ISSUE IS SO WELL KNOW THAT THERE ARE PEOPLE ON EBAY MAKING A BUSINESS TO REPAIR IT. A SIMPLE TYPE IN EBAY YUKON TAIL LIGHT WILL SHOW MULTIPLE LINKS.

INTERMITTENT BRAKE LIGHT ACTIVATION ON BOTH LEFT AND RIGHT. IT HAPPENS STOPPED AND IN MOTION. VERY DANGEROUS! IT IS A KNOWN ISSUE WITH BROKEN CONTACTS INSIDE A SEALED HOUSING. THE ISSUE IS POSTED ALL OVER THE FORUMS BUT GMC REFUSES RESPONSIBILIY.

TURN SIGNAL FAILURE ON THE PASSENGER SIDE. CAUSE BY CONDENSATION IN THE HEADLAMP ASSEMBLY. COST $1300 TO REPLACE AND GET A NEW TURN SIGNAL. A TURN SIGNAL IS $5, BUT THEN INTEGRATED LEDS COST $1300 BECAUSE THEY HAVE TO REPLACE THE WHOLE ASSEMBLY.

BRAKE LIGHT IS NOT WORKING ON PASSENGER SIDE. WENT TO REPLACE BULB AND FOUND OUT THAT ONE HAS TO REPLACE THE ENTIRE TAILLIGHT ENSEMBLE WHICH IS $700-800. IT IS SAD THAT SOMETHING IMPORTANT TO SAFETY LIKE A BRAKE LIGHT HAS TO COST THAT MUCH TO REPLACE. I RESEARCHED AND FOUND THIS TENDS TO BE A COMMON PROBLEM. SO MUCH FOR LED LIGHTS--THIS IS ALSO POOR ENGINEERING!

REAR DRIVE SIDE BREAK LIGHT IS OUT BECAUSE OF POOR CONSTRUCTION.

TL* THE CONTACT OWNS A 2015 GMC YUKON. THE CONTACT STATED THAT THE LED TAIL LIGHTS BURNED OUT PREMATURELY. THE CONTACT CALLED [XXX] AT 817-264-7746 (LOCATED AT 501 TX-114, GRAPEVINE, TX 76051) AND WAS INFORMED THAT THE TAIL LIGHT WAS A SEALED UNIT THAT NEEDED TO BE REPLACED AS A WHOLE. THE CONTACT STATED THAT THE REPAIR WAS TOO COSTLY FOR A SIMPLE BURNED OUT BULB. THE CONTACT CALLED IT A DESIGN FLAW. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE, STATED THAT NOTHING COULD BE DONE, AND OFFERED THE CONTACT A SMALL DISCOUNT FOR AN OIL CHANGE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 66,000. THE VIN WAS NOT PROVIDED. *DT INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

BRAKE LIGHTS FOR PASSENGER REAR LAMP ASSEMBLY IS NOT WORKING. THIS IS THE SECOND TIME WITHIN 25 MONTHS THAT THIS HAS HAPPENED. THE ENTIRE LAMP ASSEMBLY NEEDS TO BE REPLACED AT A COST OF $600+. THE VEHICLE HAS LESS THAN 49,000 MILES, AND IT IS NO LONGER COVERED UNDER WARRANTY. ONLINE FORUMS INDICATE THAT THIS IS A COMMON PROBLEM WITH THE BRAKE LIGHTS IN THE LAMP ASSEMBLIES. IT APPEARS THE CIRCUIT BOARDS FOR THE LED BRAKE LIGHTS ARE BREAKING.

THE PASSENGER SIDE BRAKE LIGHT DOES NOT WORK. I REPLACED THE LIGHT ASSEMBLY AND IT STILL DOES NOT WORK. THE DEALERSHIP MECHANIC SAID IT COYLD BE TGE WIRING.

THE LED REAR BRAKE LIGHTS AREN'T WORKING.

FAULTY BACK TAIL LIGHTS. THE ENTIRE ASSEMBLY FAILS WITH THE BACK BRAKE LIGHTS BEING OUT DUE TO FAULTY SOLDIERING AND PART. MAJOR SAFETY HAZARD. GM WILL NOT REPLACE.

NHTSA ODI 11186321

THE TAIL LIGHTS ARE FAULTY. THIS IS THE SECOND TIME I'VE HAD AN LED TAIL LIGHT GO OUT. SECTIONS OF THE LIGHTS COME ON AND OFF. ONE TAIL LIGHT ASSEMBLY HAS BEEN REPLACED ALREADY. THEY ALSO GET CONDENSATION ON THE INTERIOR OF THE ASSEMBLY. THIS APPEARS TO BE A COMMON THEME FOR A TAIL LIGHTS ON GM SUV'S FROM 2015-2018. THESE LIGHTS CAN BE PURCHASED FOR ANYWHERE BETWEEN $400. TO $900 RANGE FOR JUST ONE! THEY ARE ON A VEHICLE WHICH HAS A BASE PRICE OF OVER $50K AND LAST LESS THAN TWO YEARS! COME ON!

PASSENGER SIDE REAR BRAKE LIGHT WAS WORKING INTERMITTENTLY AND NOW HAS STOPPED WORKING ALL TOGETHER. THE BRAKE LIGHT UNIT IS A SEALED UNIT THAT CAN NOT BE SERVICED, IT MUST BE REPLACED ENTIRELY. VERY COMMON PROBLEM ON THIS MODEL DUE TO A FAULTY BRAKE LIGHT ASSEMBLY. FAILURE OF BRAKE LIGHTS PUTS THE SAFETY OF MY FAMILY IN JEOPARDY.

TAIL AND BRAKE LIGHTS FAILED. UPON INSPECTION IT WAS FOUND THAT THE CONDUCTIVE PLATE BETWEEN THE LEDS HAD CRACKED/BROKEN IN BOTH ASSEMBLIES.

NHTSA ODI 11184992

FAULTY, POORLY MADE TAIL LIGHTS THAT NEED TO BE ENTIRELY REPLACED (NOT JUST THE BULB) AT MORE THAN $700 EACH. WHEN SPENDING SO MUCH ON A CAR, THIS IS LITERALLY INSANE NOT TO BE COVERED UNDER ANY WARRANTY. GMC DRIVERS DESERVE MORE THAN THIS POORLY MADE LED LIGHT SYSTEM. THE PLASTIC WINDOW TRIM PIECES ALSO DETACH DUE TO CHEAP PLASTIC CLIPS. I'VE HAD TO LITERALLY USE DOUBLE SIDED TAPE AND GLUE TO STICK THEM BACK ON A $70K+ CAR. IT'S HUNDREDS OF DOLLARS TO REPLACE PIECES THAT ARE LITERALLY PART OF THE BODY OF THE VEHICLE.

THE BRAKE LIGHTS HAVE GONE OUT WITH ONLY 42000 MILES ON IT. I HAVE READ ON MESSAGE BOARDS ACROSS THE NATION THIS IS A MAJOR PROBLEM. DEALER WANTS 800 TO FIX IT.

EXTERIOR LIGHTING ISSUES. REAR RUNNING LIGHTS NOT WORKING. REAR BREAK LIGHTS ARE NOT WORKING. RIGHT SIDE BLINKER NOT WORKING IN FRONT HEAD LAMP OR REAR LIGHTING FIXTURE. WHEN THE VEHICLE IS HOOKED TO THE COMPUTER AT A GM DEALERSHIP THE COMPUTER WILL NOT SHOW WHAT THE ISSUE IS. THIS IS A SAFETY ISSUE AS I CAN NOT SAFETY DRIVE THE VEHICLE AT NIGHT DUE TO NO LIGHTS IN THE REAR OF THE VEHICLE NOR DURING THE DAY WITHOUT BREAK LIGHTS.

LEFT BRAKE LIGHT WORKING INTERMITTENTLY AND THEN WENT OUT COMPLETELY. RIGHT BRAKE LIGHT FOLLOWED IMMEDIATELY AFTER. DEALER WANTS 1550.00 TO REPLACE

NHTSA ODI 11181340

ALL LED LIGHTS HAVE WENT OUT ON RIGHT SIDE, AS WELL AS BREAK LIGHTS. THIS IS A KNOW ISSUE TO GMC, AND YET THEY WILL NOT CORRECT IT. MY QUOTE TO HAVE IT FIXED WAS 2493.00 FROM LOCAL DEALERSHIP. THAT IS CRAZY. LED LIGHTS SHOULD LAST A WHOLE LOT LONGER THAN THIS. ALSO CONDENSATION IS IN THE FRONT HEADLIGHT WITH NO HOLES OR CRACKS. IF THIS HAPPENS WITH HOUSE WINDOWS, THEY ARE REPLACED BY THE MANUFACTURER. THERE ARE SO MANY COMPLAINTS, I WILL ALSO BE CONTACTING THE BETTER BUSINESS BUREAU. GMC KNOWS THERE IS A PROBLEM WITH THESE MODELS.

MY REAR TAIL LIGHT WENT OUT 1 MONTH AFTER WARRANTY ENDED. THIS HAPPENS TO ALL MANY AUTOS IN THIS CLASS. PLEASE DO SOMETHING OR I WILL STOP BUYING GMC AUTOS.

OUR PASSENGER TAILLIGHT WENT OUT AND THE DEALERSHIP COST TO REPLACE IT WAS $811. I CALLED GMC CUSTOMER SERVICE AND AFTER 4 DAYS AND MULTIPLE PHONE CALLS THE BEST THEY COULD OFFER IN FINANCIAL ASSISTANCE WAS $80. I ASKED THE DEALERSHIP IF I COULD HAVE THE BROKEN LIGHT AND THEY WANTED ME TO PAY $50 TO TAKE IT WITH ME. A GOOGLE SEARCH TURNED UP MANY INSTANCES OF THIS HAPPENING. THE DEALERSHIP TOLD ME THAT THEY REPLACE 1-2 PER WEEK. THE TAILLIGHT REPLACEMENT ON THE YUKON FAMILY IS A SCAM. IT IS UNETHICAL FOR THEM TO CHARGE THAT MUCH FOR A REPLACEMENT WHEN IT IS INOWN TO BE DEFECTIVE. THE CAR IS LESS THAN 4 YEARS OLD AND HAS 66K MILES AND HAS NOT BEEN IN ANY COLLISIONS. JUST NORMAL ROUTINE USE RESULTED IN A COSTLY REPAIR AND, MORE IMPORTANTLY, IRRESPONSIBLE CUSTOMER SERVICE FROM THE GMC EMPLOYEES WHO WERE IN CHARGE OF HANDLING MY CASE.

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.
