TAIL LIGHT CIRCUIT (LED INTERNAL TO HOUSING) CRACKS, CAUSING RAIL/BRAKE LIGHT OUTAGE WITH NO WARNINGS ON THE DASH FOR THE DRIVER. THIS IS A MATERIAL DEFECT IN THE METAL STAMPING USED FOR THE LED POWER CIRCUIT. EXACERBATED BY HEAT AND VIBRATION.
THE PASSENGER SIDE BRAKE/TAIL LIGHTS INTERMITTENTLY DO NOT WORK. THEY WORK ABOUT 60 PERCENT OF THE TIME AND THE OTHER 40 PERCENT THEY DO NOT. I HAVE READ MANY COMPLAINTS ONLINE ABOUT THIS ISSUE AND GM NEEDS TO STEP UP AND GET IT FIXED. IT IS A SAFETY ISSUE.
BRAKE/TAIL LIGHTS HAVE GONE OUT. MY CAR ISN'T EVEN 5 YEARS OLD. THE REPAIR IS ASTRONOMICAL'AT LEAST $1500!!!
MY DRIVER'S SIDE TAIL LIGHT FLICKERED FOR ABOUT 2 MONTHS BEFORE FINALLY GOING OUT. THE OTHER SIDE IS NOW DOING THE SAME THING. IT HAS 82,301 MILES ON IT.
I HAVE BEEN HAVING ISSUES FOR ABOUT A YEAR WITH THE LIGHTS WORKING INTERMITTENTLY. AS OF TODAY, JUNE 12 2019, THEY ARE OUT COMPLETELY!!!! AFTER GOING TO A LOCAL MECHANIC HE SAID THE WHOLE CIRCUIT WAS GONE & WOULD HAVE TO BE REPLACED!!! I AM IN BETWEEN JOBS AND DO NOT HAVE 2000.00 DOLLARS TO FIX SAID PROBLEM. I HAVE FOUND SEVERAL MESSAGE BOARDS WHO HAVE ALL HAD THE SAME PROBLEM WITH NO HELP WHAT SO EVER FROM GMC!!!!! THIS IS RIDICULOUS. WHEN YOU MAY THOUSANDS OF DOLLARS FOR A SUV YOU EXPECT IT TO LAST LONGER THAN 88,000!!! THIS ISN'T THE FIRST PROBLEM I HAVE HAD WITH THIS SUV. SO THIS NEEDS TO BECOME A RECALL ISSUE AND GMC OR THE PART SUPPLIER NEEDS TO FIX THIS.
THE LEFT BRAKE LIGHT FAILED WITH 57K MILES. THE RIGHT ONE THEN FAILED AT 61K MILES. THE DEALER WANTED $735 EACH TO FIX THEM, AS THEY CLAIM THEY NEED TO REPLACE THE ENTIRE LED HOUSING. THE DEALER IS WELL-AWARE THAT THIS IS A COMMON PROBLEM, AND IT WOULD APPEAR BASED ON GOOGLING THE ISSUE THAT MANY OTHERS HAVE EXPERIENCED THIS FAILURE FROM GM.
THE TAIL LIGHT FAILED WITH NO PHYSICAL DAMAGE. I FEEL THIS IS A LATENT DEFECT THAT GM IS AWARE OF BUT WILL NOT TAKE RESPONSIBILITY FOR IT. THIS A SEALED UNIT CAUSING OWNERS TO PAY EXORBITANT AMOUNTS TO REPLACE THE UNIT. THERE ARE MANY REPORTS OF THIS ITEM FAILING IN THE FIELD WITHIN AN UNACCEPTABLE TIME PERIOD. PRODUCTION DATE ON OUR UNIT IS APR/24/14, SO JUST OVER A FIVE YEAR PERIOD ON A VEHICLE WITH LESS THAN 80K MILES.
WE PURCHASED A USED 2015 YUKON DENALI LESS THAN 6 MONTHS AGO AND BOTH TAIL LIGHTS HAVE NOW GONE OUT. AFTER READING ABOUT THE ISSUE, IT SEEMS LIKE THIS IS A VERY COMMON ISSUE WITH LIGHTS ON THIS VEHICLE. VERY UNFORTUNATE THAT GMC REFUSES TO DO ANYTHING ABOUT IT.
TAILLIGHTS WORKING INTERMITTENT. THIS IS A SAFETY ISSUE. I HAVE GOOGLE AND THERE OVER A 100 COMPLAINTS ON CAR GURUS WITH THE SAME PROBLEM. THIS IS A GMC SAFETY PROBLEM. THESE YUKON'S ARE EXPENSE AND I SHOULD FEEL SAFE WHILE DRIVING IT. TAKING IT TO THE DEALERSHIP THIS MORNING. I AM ASKING A CUSTOMER OF GMC--- DO THE RIGHT THING AND LOOK INTO THIS AS SOMEONE IS GOING TO GET KILLED - NO TAILLIGHTS COULD BE A LIFE THREATING SAFETY ISSUE. GMC DO THE RIGHT THING. LOOK AT ALL OF THE COMPLAINTS WITH THE EXACT SAME ISSUE
THE REAR DRIVER SIDE TAILLIGHT DOES NOT WORK. TOOK IT TO THE DEALERSHIP AND THEY SAID IT WAS A PROBLEM THEY SAW FREQUENTLY, TO JUST HIT THE LIGHT AND IT MIGHT START WORKING. OTHERWISE IT WAS A 800 DOLLAR LIGHT TO REPLACE....IF IT IS A FREQUENT PROBLEM GMC SHOULD BE FIXING IT... ARE THEY GOING TO PAY FOR A TICKET IF I GET PULLED OVER OR WORSE SOMEONE CRASHES INTO ME? THE PROBLEM COMES AND GOES BUT HAS SEEMED TO GET WORSE AND IS NOT SAFE OR LEGAL TO DRIVE WITH THE LIGHT HOW IT IS. BAD DESIGN OF THE LIGHT. AND FROM WHAT I HAVE SEEN ONLINE I AM NOT THE ONLY ONE. THERE A WHOLE FORUMS THAT PEOPLE HAVE THE SAME ISSUE.
PASSENGER SIDE REAR TAIL LIGHT/ BRAKE LIGHT INOPERABLE. PROBLEM OCCURRED AT 44,580 MILES.
LED BRAKE LIGHT WORKS INTERMITTENTLY.
THE PASSENGER SIDE TAIL LIGHT IS INTERMITTENT THE DEALER SAID THAT IT WOULD COST $875.00 FOR THE PART TO FIX. HE SAID THAT IT WAS A BAD MANUFACTURING JOB. AND HE ALSO SAID THAT THERE WERE A LOT OF SUV'S COMING IN WITH THE SAME PROBLEM. THANK YOU
REAR DRIVE SIDE BREAK LIGHT IS OUT BECAUSE OF POOR CONSTRUCTION.
LED TAIL LIGHT AND BRAKE LIGHT STOPPED WORKING AT APPROX. 50,000 MILES.
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.
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!
REAR LED BRAKE LIGHTS ONLY WORK INTERMITTENTLY.
REAR LED TAIL LIGHTS STOP WORKING DUE TO CRACKED BRIDGE ON CIRCUIT BOARD OF LIGHT ASSEMBLY.....NON SERVICEABLE NEW TAIL LIGHT IS $600-$700. POSSIBLE COLLISION HAZARD!
MY RIGHT REAR TAILLIGHT STOPPED WORKING, INCLUDING THE BRAKE LIGHT. I TOOK IT TO THE DEALERSHIP AND WAS TOLD IT IS A BURNED OUT TAILLIGHT AND HAS TO BE REPLACED. THE COST WAS $800. I WAS UNDER THE IMPRESSION THAT THESE TAILLIGHTS ARE LED AND LAST FOREVER. IN READING ONLINE, IT LOOKS LIKE THIS IS AN ONGOING PROBLEM WITH THESE GMC/CHEVY TAILLIGHTS WHERE THE CIRCUIT BOARD BREAKS AND THE LIGHT STOPS WORKING.
BRAKE LIGHTS WORKING INCONSISTENTLY,
BRAKE LIGHTS WENT OUT ON BOTH SIDES. ALL OTHER LIGHTS IN UNIT ARE FUNCTIONING FINE. GMC IS REQUIRING ME TO BUY THE ENTIRE LIGHT WHICH IS $750 EACH JUST TO FIX THE BRAKE LIGHT. BOTH LIGHTS WENT OUT AT THE SAME TIME. HAS TO BE AN ISSUE WITH THE LIGHT
TAKATA RECALL. ISSUES WITH BOTH BRAKE LIGHTS GOING OUT.
RIGHT TAIL LIGHT ISN'T WORKING. JUST BOUGHT THE CAR.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
