What 269 owners told NHTSA about the 2016 GMC Yukon Denali Xl

REAR TAIL LIGHT WORKS INTERMITTENTLY CAUSING A RISK OF BEING REAR ENDED. THROUGH RESEARCH THIS APPEARS TO BE AN ISSUE WITH MANY VEHICLES OF THIS MAKE AND MODEL. GMC ALSO CHARGES AN OUTRAGEOUS PRICE FOR THE REPLACEMENT AT $1000 FROM THE DEALER.

LED TAILLIGHT ON 2016 YUKON DENALI IS NOT WORKING. THIS IS THE SECOND TIME THIS HAS HAPPENED. THIS IS A COMMON ISSUE AND GM WILL NOT COVER A KNOWN ISSUE.

NHTSA ODI 11204819

THE REAR TAIL/BRAKE LIGHTS ON THE GMC YUKON SERIES HAVE A DEFECT THAT KEEP CAUSING THE RUNNING LIGHTS AND BRAKE LIGHTS TO WORK INTERMITTENTLY. I HAD AN ENTIRE NEW LIGHT INSTALLED AND THE SAME ISSUE OCCURRED WITHIN A FEW THOUSAND MILES. GMC IS AWARE OF THIS PROBLEM AND HAS YET TO ISSUE A RECALL FOR THESE DEFECTIVE LIGHTS. OBVIOUSLY THIS IS AN IMPORTANT SAFETY FEATURE OF THE VEHICLE IN ORDER TO ALERT OTHER DRIVERS OF MERE PRESENCE, BRAKING, AND TURNING ACTIONS.

THE AIR CONDITIONING CONDENSERS AND ASSOCIATED PARTS ARE FAILING ON THE 2016 GMC YUKON. GMC HAS YET TO ISSUE ANY RECALL EVEN THOUGH THESE AC UNITS ARE CONSTANTLY BREAKING ON THESE VEHICLES.

STARTED THE VEHICLE AFTER IT HAD BEEN SITTING FOR ABOUT 1 HOUR AND THE GAUGES DID THEIR REGULAR CHECK SWEEP FROM LEFT-TO-RIGHT, THEN THE FOLLOWING WARNINGS APPEARED ON THE DRIVER INFORMATION DISPLAY SCREEN: 1) SERVICE AIR BAG; 2) SERVICE TRAILER BRAKE, AND; 3) SERVICE FRONT CAMERA. AFTERWARDS, THERE WERE NO GAUGES EXCEPT THE VOLTMETER (TACHOMETER, FUEL, TEMPERATURE, OIL PRESSURE AND SPEEDOMETER WERE ALL AT RESTING POSITIONS). THE DRIVER INFORMATION SCREEN WOULD NOT SHOW THE GEAR SELECTOR, THE MILEAGE OR THE SPEED AND THE WARNING LIGHTS FOR THE AIRBAG, EMERGENCY BRAKE, TRACTION CONTROL AND TPMS STAYED ON. I DROVE THE VEHICLE A SHORT DISTANCE AND SHUT IT OFF, RESTARTED, AND IT DID NOT MAKE ANY DIFFERENCE. THERE WAS NO OPTION TO TAKE THE VEHICLE TO A DEALERSHIP FOR SERVICE IMMEDIATELY, BECAUSE WE HAD A TRAIN TO CATCH, SO WE HAD TO DRIVE IT ABOUT 20 MILES WITH NO SPEEDOMETER, BUT WE CALLED OUR GMC DEALER AND MADE A SERVICE APPOINTMENT FOR APRIL 22, 2019 ONCE WE PARKED AT THE TRAIN STATION. THE VEHICLE WAS PARKED UNTIL APRIL 21, 2019, AND, WHEN STARTED AT THAT TIME, THE INSTRUMENT PANEL AND DRIVER INFORMATION SCREEN WORKED CORRECTLY. ON APRIL 22, 2019, OUR GMC DEALER (WOODBRIDGE BUICK-GMC) PERFORMED A DIAGNOSTICS AND DISCOVERED A B3980 (NO ENVIRONMENT IDENTIFIER RECEIVED) IN THE HISTORY. ACCORDING TO THE SERVICE ADVISER I SPOKE TO, THIS CODE WILL INVOLVE THE RELAYS FOR THE TRAILER BRAKING AND THE INSTRUMENT PANEL. ALSO; THEY TOLD ME THAT THE BATTERY CABLE WAS LOOSE, SO THEY TIGHTENED THAT AS WELL. OUR EXTENDED WARRANTY DID NOT COVER THIS AND WE HAD TO PAY FOR THE DIAGNOSTICS DUE TO OUR MANUFACTURE WARRANTY EXPIRING 2 MONTHS BEFOREHAND. AS OF NOW, THIS PROBLEM HAS NOT HAPPENED AGAIN, BUT IT IS WORTH REPORTING DUE TO POSSIBLY BEING A SAFETY ISSUE.

PASSENGER SIDE LED BRAKE LIGHT FAILED AT 60000 MILES. $800 DEALER REPAIR QUOTE TO REPLACE. NO MANUFACTURE SUPPORT.

NHTSA ODI 11202721

PASSENGER SIDE BRAKE LIGHT NOT WORKING. YUKON HAS UNDER 40,000 MILES AND IS METICULOUSLY CARED FOR. I HAVE READ MANY OTHER COMPLAINTS ONLINE AND THIS SEEMS TO BE A QUALITY ISSUE. THERE IS NO EASY FIX AND A COMPLETE REPLACEMENT IS REQUIRED. THIS IS A SAFETY ISSUE GIVEN IT IS A BRAKE LIGHT. BRAKE LIGHTS SHOULD NOT MALFUNCTION IN THIS MANNER. A RECALL IS CERTAINLY IN ORDER AS FAILURE TO SIGNAL BRAKING CAN BE A RISK FOR MYSELF AS THE DRIVER AND OTHERS.

NHTSA ODI 11202643

RIGHT REAR BRAKE LIGHT ASSEMBLY FAILED. IT IS A SEALED ASSEMBLY AND CANNOT BE REPAIRED WITHOUT BREAKING THE SEALED/SONIC WELDED ASSEMBLY. REPLACEMENT ASSEMBLY IS $700+ DOLLARS.

THE ANTENNA ON THE YUKON GETS WATER IN IT WHEN IT RAINS. IT HAS MESSED UP MY GPS SYSTEM AND MY ON STAR SYSTEM IS NOT WORKING. IT HAS LEAKED INTO THE SUV. THIS HAPPENS EVERY TIME IT RAINS.

VEHICLE IN MOTION AND BRAKES WOULD NOT WORK UNLESS YOU PUT ALL YOUR BODY WEIGHT ON THE BRAKES, AND THEN JUST BARELY. HAPPENED MULTIPLE TIMES ON AND OFF BOTH AT HIGH RATE OF SPEED ON HIGHWAY AND ON CITY STREETS. TOOK INTO GMC DEALERSHIP AND THEY REPLACED THE VACUUM PUMP FOR THE BRAKES -- PROBLEM SOLVED AFTER SPENDING $800. WE ARE LUCKY THIS IS A MAJOR SAFETY ISSUE THAT COULD HAVE CAUSED A SERIOUS ACCIDENT. I UNDERSTAND THIS EXACT PROBLEM IS A KNOWN PROBLEM CURRENTLY BEING INVESTIGATED. PLEASE FINISH YOUR INVESTIGATION QUICKLY AND ISSUE A RECALL -- SOMEBODY IS GOING TO GET KILLED IF THIS IS NOT FIXED. I LOOK FORWARD TO BEING REIMBURSED FROM GMC WHEN THE RECALL IS FINALLY ISSUED.

MY WIFE'S 2016 GMC PASSENGER TAIL LIGHT FLICKERING WORKING WHEN IT WANTS. TRUCK HAS 50K NEVER BEEN IN ACCIDENT AND WE ARE THE ORIGINAL OWNERS.

NHTSA ODI 11193468

OEM LED TAIL LIGHTS HAVE FAILED ON MY GMC WITH 40,000 MILES ON IT. THE BULB IS GOOD, YET THE LED PORTION (WHICH COSTS OVER $800 TO FIX) NEEDS TO BE REPLACED. THIS PORTION IS THE ENTIRE REAR BRAKE LIGHT HOUSING. THIS IS VERY COMMON AMONG THESE VEHICLES HEATED SEATS QUIT WORKING ON DENALI. THE BACKRESTS STILL HEAT UP, BUT THE BOTTOMS DON'T HEAT UP AT ALL. ALSO, THEY WILL NOT TURN ON IN REMOTE START MODE EVEN THOUGH THEY ARE SET TO TURN ON IN THIS MODE.

VACUUM PUMP WENT OUT ON MY VEHICLE RESULTING IN ALMOST BEING HIT BY A SEMI TRAVELING 65MPH. I HAD TO CALL A WRECKER TO PICK UP MY VEHICLE AND HAVE IT TOWED TO THE DEALERSHIP AS IT WAS NO LONGER SAFE TO DRIVE. I PAID OUT OF POCKET FOR THE WRECKER AND THE REPAIR BECAUSE THE VACUUM PUMP WAS NO LONGER COVERED UNDER WARRANTY AT 38,633 MILES. I WAS LEAVING A DRIVEWAY AT A SLOW SPEED TO TURN ONTO A FARM TO MARKET ROAD AND MY BRAKES WOULD NOT WORK.

THIRD TIME THIS HAPPENED, FIRST TWO TIMES MY HUSBAND WAS DRIVING(HE CALLED THE DEALERSHIP AND THEY SAID THEY HAD NOT HEARD OF ANY PROBLEMS) AND WHEN IT HAPPENED TO ME IT WAS SCARY. I HAD MY KIDS IN THE CAR, NO INJURIES AND NO ONE WAS HURT, THANK GOD. I WAS GOING THROUGH THE DRIVE THRU STOPPED AT THE FIRST WINDOW, ACCELERATED TO NEXT WINDOW (LOW SPEED) AND DIDN'T STOP... IT WAS THE LIKE THE BRAKES LOCKED UP, COULDN'T PRESS DOWN AT ALL. CALLED THE DEALERSHIP FIRST THING IN THE MORNING, SAME THING DIDN'T KNOW OF ANY ISSUES. WELL I GOOGLED IT AND IT IS UNDER INVESTIGATION, SO I KINDLY PRINTED OFF ALL THE ARTICLES SO THEY COULD LET OTHER CUSTOMERS KNOW THERE WAS AN ISSUE (THEY DIDN'T CARE TO KEEP THAT BUT DID ADMIT THEY KNEW THERE HAD BEEN SOME ISSUES). OF COURSE MY CAR IS JUST OUT OF WARRANTY SO THEY SAID I WOULD BE RESPONSIBLE FOR ANY ISSUES. AGAIN, THIS IS A SAFETY ISSUE AND THERE SHOULD BE A RECALL!!! THEY SHOULD BE PAYING FOR IT AND THANKING THERE LUCKY STARS NO ONE WAS INJURED. THE TOTAL CAME TO $950, THEY ASKED IF I WANTED THEM TO FIX THE PUMP, BELT AND BELT KIT (I ASKED IF THIS WAS THE ISSUE OTHERS WERE HAVING AND HE SAID HE BELIEVES SO). WHAT WAS I GOING TO SAY NO? DID I REALLY HAVE AN OPTION?? THE BRAKES WEREN'T WORKING!!!! KIND OF A BIG DEAL!! OF COURSE I WOULD LIKE THEM TO PAY ME BACK (THEY DID GIVE ME A CREDIT OF $208) BUT I DO BELIEVE THEY NEED TO DO A RECALL BEFORE SOMEONE GETS HURT.

FAULTY TAIL LIGHT HOUSING, RESULTS IN TAIL/BRAKE LIGHTS NOT WORKING. NOT THE RESULT OF DAMAGE, SIMPLY BAD DESIGN IN THE LED HOUSING AND ELECTRICAL CONNECTIONS. THE ELECTRICAL CONNECTION WAS POORLY CONSTRUCTED, AND THE ONLY FIX IS TO COMPLETELY REPLACE THE ENTIRE HOUSING AT $750 INCLUDING LABOR.

NHTSA ODI 11180154

THE LED BRAKE LIGHT DOES NOT WORK. THE LIGHT IS AN ENTIRE ASSEMBLY THAT OWNERS MUST REPLACE BY BUYING A NEW UNIT FOR $700. THE UNIT IS SUPPOSED TO LAST FOR THE LIFE OF THE CAR. IT'S A DEFECTIVE PIECE THAT IS DIFFICULT AND EXPENSIVE TO REPLACE.

I DRIVE 2016 GMC YUKON, AND THE ENTIRE TAIL LIGHT ON THE PASSENGER REAR SIDE HAS GONE OUT ON IT. I READ ABOUT SEVERAL PEOPLE WITH THE SAME YEAR AND MODEL TRUCK HAVING THIS ISSUE. I FEEL LIKE GMC SHOULD DO A RECALL BECAUSE MY VEHICLE ISN'T THREE YEARS OLD YET.

THE REAR TAIL LIGHT IS NOT WORKING PROPERLY. AROUND DECEMBER 17, 2018 I WAS DRIVING MY VEHICLE ON THE CITY STREET AND HIGHWAY WHEN SEVERAL PEOPLE ADVISE ME MY LIGHT WAS OUT AND NOT WORKING. I CHECK IT ONCE ARRIVED AT HOME AND IT WAS WORKING PROPERLY AND DIDN'T PROBLEM. AND A WEEK LATER SAME ISSUE FROM PEOPLE PULLING ME OVER TO ADVISE ME MY TAIL LIGHT WAS OUT. AROUND JANUARY 10, 2019, I WENT IN TO HUTCHINSON AUTO MALL GMC DEALER AND THEY ADVISE ME EVERYTHING IS WORKING PROPERLY AND DOESN'T SEE A PROBLEM, AND ADVISE ME TO BRING BACK SHOULD I EXPERIENCE THE OUTAGE AGAIN. I INSPECT VEHICLE AS WELL AND SEEM NO PROBLEM. 23 JANUARY 19 SAME PROBLEM AND WENT BACK TO DEALER AND THEY DISCOVER THE OUTAGE AND ADVISE ME THE LED TAIL LIGHT STRIP WAS OUT AND NEED TO REPLACE THE ASSEMBLY. IT APPEARS THEIR SEEM TO BE A WIRING ISSUE WHERE THE LIGHT IS AND OUT. TO KEEP FROM A SERIOUS PROBLEM OR FIRE. REQUEST IMMEDIATELY INVESTIGATION. THE TECHNICIAN ALSO ADVISE ME THIS SEEMS TO BE A COMMON PROBLEM.

BRAKES FAIL AT LOW SPEEDS AND WHEN REVERSING SLOWLY. CAN REPLICATE PROBLEM. SEARCHED INTERNET AND THIS APPEARS TO BE A WIDESPREAD PROBLEM. SERVICE BULLETINS HAVE EVEN BEEN WRITTEN. WHY NO RECALL FOR A WIDESPREAD ISSUE THAT COULD HAVE CATASTROPHIC CONSEQUENCES. . VEHICLE HAS LESS THAN 50000 MILES.
