What 497 owners told NHTSA about the 2016 GMC Yukon Denali Xl 1500

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.

BRAKE LIGHTS STOPPED WORKING ALMOST WAS PLOWED INTO BY 18 WHEELER ON I-75. DRIVER WAVED US OVER AND INFORMED US THAT HE DID NOT SEE US TILL RIGHT ON TOP OF US. PROBLEM APPEARS TO BE SYSTEMIC ENOUGH THAT THE GMC SERVICE DEPARTMENT TOLD US THAT IT WAS COMMON ENOUGH THAT THEY KEPT THE BRAKE LIGHTS IN STOCK. ADDITIONALLY THERE ARE NUMEROUS THREADS ABOUT THIS ISSUE ON THE INTERNET AND EVEN UTUBE VIDEOS ON WHERE TO REMOVE MATERIAL TO ACCESS THE OFFENDING CIRCUIT BOARD TO REPAIR THE KNOWN FAULTY CIRCUIT. THE FAILURE OF THESE BRAKE LIGHTS COULD HAVE COST MY FAMILY AND ME OUR LIVES. THE DEALERSHIP WANTED TO CHARGE 1600$ TO REPLACE THE BRAKE LIGHTS. I REITERATE THE BRAKE LIGHT FAILURE IS COMMON ENOUGH THAT THERE ARE NUMEROUS THREADS ON THE INTERNET TO DISCUSS THE KNOWN WEAKNESS OF THE CIRCUIT BOARD

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.

MY COMPLAINT RELATES TO A KNOWN DEFECT IN 2015-18 GMC YUKON (AND SIMILAR GM MODELS) AND DEFECTIVE BRAKE LIGHTS. THE LEFT BRAKE LIGHT IN MY 2016 GMC YUKON WENT OUT IN APPROX EARLY 2019. IT WAS REPAIRED UNDER WARRANTY. IN NOVEMBER 2019, BY RIGHT BRAKE LIGHT WENT OUT. IT WAS THE SAME PROBLEM AS THE EARLY BROKEN LIGHT. I HAD LESS THAN 36,000 MILES ON THE VEHICLE. I LEASED THE VEHICLE IN APPROX SEPT 2016 AND THE DEALER CLAIMED THAT THE VEHICLE WAS PAST (LESS THAN 75 DAYS) EXPIRATION OF THE 36 MONTH WARRANTY. SO, THE DEALER QUOTED ME $950+/- DOLLARS TO REPLACE THE ENTIRE HOUSING. THE DEALER REP EXPLAINED THAT THE ENTIRE HOUSING HAD TO BE REPLACED BECAUSE IT WAS LED AND DIDN'T USE A BULB. THE DEALER REP TOLD ME THIS IS A COMMON PROBLEM. I WAS INCENSED AND REFUSED TO PAY. I WENT HOME AND GOOGLED THE PROBLEM AND FOUND OUT THAT THIS IS PERVASIVE WITH THE 2015-18 YUKON AND OTHER SIMILAR GM PRODUCTS. I ALSO FOUND A FIX THAT WAS MUCH LESS MONEY ONLY REQUIRED ABOUT 2 HOURS OF MY TIME. THIS IS A SAFETY DEFECT AND, BASED ON THE DEALER REP COMMENT AND GOOGLE RESEARCH, IT IS A WELL KNOWN PROBLEM.

A BROKEN BRAKE LIGHT IS A SAFETY DEFECT. GM SHOULD BE FORCED TO RECALL ALL OF THE 2015 - 2019 AND REPLACE THE BRAKE LENSES.

BRAKE LIGHT ON VEHICLE WORKS INTERMITTENTLY AND IS NO LONGER SAFE. THIS IS A PROBLEM GMC IS WELL AWARE OF AND NO SOLUTION IN SIGHT. CHEAP METAL BOARD BRAKES INSIDE THE LENS AND LEAVES YOU WITH NO BRAKE LIGHT. I DO NOT WANT MY FAMILY TO BE REAR ENDED BECAUSE OF THIS PROFESSIONAL GRADE? BRAKE LIGHT FAILURE, AT ANY TIME ON ROAD.THIS IS A 2016 GMC YUKON WITH 22710 MILES AS I WRITE. BRAKE LIGHT HAS FAILED WHILE MOVING ON THE CITY STREETS. THIS FAILURE IS CURRENTLY ON THE PASSENGER SIDE BRAKE LIGHT. TRYING TO MAKE APPOINTMENT FOR REPAIR OF THIS PROFESSIONAL GRADE BRAKE LIGHT? BEFORE THE OTHER ONE BRAKES AND PUT MY FAMILY AT RISK OF A ACCIDENT.

LEFT TAILLIGHT WENT OUT AND I WAS UNDER THE WARRANTY AND THE DEALER REPLACED IT BUT HAD THE RIGHT TAILLIGHT GO OUT AT 40,000 MILES. I HAVE REFERRED 4 FRIENDS THAT PURCHASED THE SAME VEHICLE AS US AND HAVE HAD THE SAME ISSUES. THIS IS A COMMON PROBLEM WITH GMC AND THEY NEED TO RECALL THIS.

PASSENGER SIDE BRAKE LIGHT STOPPED WORKING (BOTH IN MOTION AND STATIONARY). IT LOOKS LIKE MANY OWNERS ARE ALSO EXPERIENCING THIS PROBLEM, SO WOULD BE GREAT IF AN INVESTIGATION COULD BE STARTED.

MIDDLE ROW DVD SCREEN IS BLACK AND NOT WORKING. REAR BRAKE LIGHTS WORKING OFF AND ON. HORRIBLE LOUD SQUEALING SOUND UNDER THE HOOD. THE VEHICLE WILL ALSO BEGIN TO SHAKE RANDOMLY AND FEELS JUMPY AT TIMES.

TAIL LIGHTS ALTERNATING NOT WORKING. THERE SEEMS TO BE SOME ELECTRICAL ISSUE WITH THE LED TAIL LIGHTS. THIS IS A MASSIVE PROBLEM AND ALL OVER THE INTERNET. GMC IS CHARGING $1000 PER TAIL LIGHT TO FIX DESPITE THIS BEING A DEFECT.

BRAKE LIGHTS & TORQUE CONVERTER 2016 YUKON DENALI. THE BRAKE LIGHT IS OUT ON THE PASSENGER SIDE. I BROUGHT IT TO THE DEALERSHIP, AND IT IS WITHIN 2 WEEKS OF THE WARRANTY EXPIRING. THEY HAD TO ORDER THE PART BECAUSE THERE'S A NATIONAL BACKORDER FOR THE ASSEMBLY. SO CLEARLY I'M NOT THE ONLY ONE. DID SOME RESEARCH AND THIS IS APPARENTLY AN ONGOING PROBLEM. THIS VEHICLE HAS BEEN A HASSLE FROM THE START. I'M BEGINNING TO BELIEVE THERE IS AN ELECTRICAL ISSUE AS WELL. I HAD A BATTERY ISSUE THAT THE DEALERSHIP COULDN'T FIGURE OUT EVEN AFTER SHOWING THEM THE ONSTAR ALERT. ORIGINALLY I WAS TOLD ONSTAR WAS PROBABLY JUST SENDING IT AS A MILEAGE ALERT. TURNS OUT AFTER I INSISTED THEY PUT THE VEHICLE ON A MACHINE AND IT SHOWED THE BATTERY WAS INDEED FAULTY. MULTIPLE THINGS HAVE GONE OUT ON A VEHICLE WITH BARELY 30,000 MILES ON IT. THE TORQUE CONVERTER IS ALSO A MAJOR CONCERN BECAUSE IT 'SHED' METAL PIECES WITH THE CAR HAVING LESS THAN 20,000 MILES THEY ONLY DRAINED THE TRANSMISSION FLUID BECAUSE THAT'S WHAT THE BULLETIN TOLD THEM TO DO. HOW IS THIS NOT GOING TO HAPPEN AGAIN? MY YUKON DROVE LIKE A LAWNMOWER VIBRATING AND HOPPING. THIS IS THE WORST VEHICLE I'VE EVER PURCHASED, AND WITH THE ISSUES THAT KEEP PILING UP IT LOOKS LIKE WE AREN'T ANYWHERE NEAR THE BOTTOM OF THE PROBLEMS.

AT 64,497 MY WIFE'S POWER STEERING WENT OUT ON HER VEHICLE. THIS HAPPENED A DAY AFTER OUR TRIP TO ATLANTA, GA. WE TOOK IT TO OUR LOCAL GMC DEALERSHIP AND WAS NOTIFIED THAT 4 MODULES HAD TO BE REPLACED AND A RECOMMENDED WIRING HARNESS. IN 2015 GMC VEHICLES HAD A SIMILAR ISSUE AND RECALL BUT NOT THE 2016. THIS COST ME $1400 IN REPAIRS.

AT LESS THAN 3 YEARS OLD AND 60K MILES, THE FOLLOWING HAS OCCURRED AT DIFFERENT TIMES UP UNTIL NOW: OVERALL ELECTRICAL MALFUNCTION INCLUDING DISPLAY ILLUMINATION FAILURE (DISPLAY GOES COMPLETELY BLACK AND/OR DIM WHILE DRIVING - CANNOT SEE SPEEDOMETER ETC. THIS HAS HAPPENED MULTIPLE TIMES WHILE DRIVING ON BOTH THE HIGHWAY AND SURFACE STREETS, INCLUDING DAYTIME AND NIGHTTIME), AUDIO/ENTERTAINMENT SYSTEM GLITCHES (RADIO VOLUME CHANGES TO AND GETS STUCK RANDOMLY ON HIGHEST VOLUME SETTING (WAS NEVER EVEN SET TO THIS LEVEL) WHILE DRIVING, CAUSING SUDDEN DISTRACTION/DISRUPTION), TAIL LIGHT MALFUNCTION (INTERMITTENTLY STOPS WORKING BOTH LEFT AND RIGHT SIDES), AND NOW THE MOTOR TO THE SUNROOF HAS DIED (OCCURRED WHILE DRIVING AND AT A MOMENT WHEN IT WAS NECESSARY TO CLOSE FOR SAFETY ON THE HIGHWAY.) THE TRANSMISSION IS DEFECTIVE (FOR THE SECOND TIME - OFF SHIFTS AND DOWNSHIFTS UNEXPECTEDLY WHILE DRIVING AT BOTH LOWER AND HIGHER SPEEDS. HAS HAPPENED ON THE HIGHWAY REQUIRING ME TO PULL OVER AND RESTART THE VEHICLE.) THESE INCIDENTS HAVE BEEN OCCURRING FOR THE PAST SEVERAL MONTHS, BUT BECAUSE THEY HAVE BEEN INTERMITTENT IT HAS BEEN HARD TO PINPOINT WHEN TO BRING IN TO THE DEALERSHIP FOR INSPECTION.

WE WERE TRAVELING IN OUR YUKON WHEN ALL POWER WAS LOST TO THE VEHICLE. THE STEERING WHEEL LOCK FUNCTION ENABLED BEFORE WE WERE STOPPED. SINCE THERE WAS NO POWER AND IT IS PUSH BUTTON START, THERE WAS NO WAY TO CONTROL THE VEHICLE. OUR DEALER SAID TO THEIR KNOWLEDGE THERE IS NO WAY TO UNLOCK THE WHEEL. LUCKILY OUR CHILDREN WERE NOT IN THE VEHICLE AND NO ONE WAS INJURED. THE DEALER SAID THE NEGATIVE BATTERY CABLE IS FULLY INTACT, BUT HAD FAILED INTERNALLY. WHAT IS MORE CONCERNING IS THE FACT THERE IS NO WAY TO UNLOCK THE WHEEL TO STEER IF THIS HAPPENS. EVEN AT 65 MPH.

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.

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.

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.
