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

I PURCHASED MY TRUCK FROM GILROY CHEVROLET IN SEPTEMBER 2019. THE WEEK WE BOUGHT IT MY HUSBAND HAD TO CHANGE THE BREAKS AS THEY NEEDED TO BE CHANGED. SHORTLY AFTER WITHIN A WEEK FROM THAT WE STARTED HEARING A POPPING SOUND FROM THE LEFT FRONT PART OF THE TRUCK. SOMEWHERE NEAR THE AXEL OR TIRE BARING. I CONTACTED THE DEALER AND STATED THEY HAD SOLD ME A CAR WITH NO BREAKS AND WITH THIS MYSTERIOUS NOISE. THEY DIAGNOSED THE CAR, CHARGED ME AND DIDN'T FIX THE PROBLEM I DIDN'T EVEN GET REIMBURSED OR AN APOLOGY FOR BEING SOLD A CAR THAT HAD NO BREAKS. I HAVE TAKEN MY CAR TO A NEW DEALER FOR FURTHER DIAGNOSIS. WHERE THEY ARE ASKING ME TO PAY FOR A DIAGNOSTIC FEE AND DEDUCTIBLE I FEEL THE ORIGINAL DEALER WHO SOLD ME THIS DEFECTIVE CAR SHOULD HAVE TO PAY SINCE I HAVE PAID THESE DUE ONCE ALREADY. ANY TIME THE STEERING WHEEL IS TURNED ALL THE WAY YOU FEEL AND HEAR THE POPPING NOISE.

WATER LEAKED INTO THE VEHICLE'S ROOF MOUNTED ANTENNA. THIS CONDITION PREVENTED THE VEHICLE'S ONSTAR SYSTEM FROM ACCURATELY DETERMINING THE VEHICLE'S LOCATION; DISABLED THE VEHICLE'S COMPASS, NAVIGATION, AND XM RADIO SYSTEMS; ILLUMINATED THE VEHICLE'S RED ONSTAR INDICATOR; AND ALLOWED WATER INTO THE INTERIOR DRIVER COMPARTMENT. THIS CONDITION OCCURRED IN BOTH THE STATIONARY AND IN MOTION STATES. GM ISSUED PRODUCT BULLETIN # 15155 FOR 2015 MODEL YEAR FOR THE SAME ISSUE, BUT DID NOT CORRECT FOR 2016 MODEL YEAR. ISSUE RELATED TO REPLACEMENT OF PART # 23258460. THIS PART WAS REDESIGNED FOR 2017 MODEL YEAR TO ELIMINATE THE DESIGN DEFECT BY RELOCATING THE MOISTURE WEEP HOLE ON THE BASE GASKET FROM THE REAR TO THE FRONT TO ACCOMMODATE THE ROOF SLOPE.

BOTH HEAD LAMPS HAVE MOISTURE AND IT IS HARD TO SEE THE ROAD. I HAVE EXTENDED WARRANTY AND IT WILL NOT COVER LENSES. NO WARRANTY WILL. EVENTUALLY THE MOISTURE WILL HARD THE LED AND HID COMPONENTS AND THEY WILL NOT WORK AT ALL CAUSING A HAZARD TO MY FAMILY AND OTHERS. MY CAR HAS 37000 MILES ON IT AND IS GARAGE KEPT. THESE LAMPS ARE OVER $2000.00 TO REPLACE.

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.

TAIL LIGHTS SUDDENLY STOPPED WORKING. CALLED THE DEALER AND WAS TOLD $800. TO REPLACE. THE DEALERSHIP TOLD ME EVERYONE IS HAVING THIS PROBLEM WHY IS IT NOT A RECALL? I RESEARCHED THE PROBLEM ONLINE AND EVERYBODY IS COMPLAINING ABOUT THIS ISSUE.

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.

THIS CAN BE RESEARCHED BY HUNDREDS OF VIDEOS ON YOUTUBE. POOR DESIGN CAUSES THE METAL TO BREAK INSIDE THE LED REAR TAIL LIGHTS WHICH MAKES THEM INOPERABLE. THESE ARE UNSAFE WHEN THESE GO OUT AND IT IS VERY COMMON. GENERAL MOTORS DOES WARRANTY THEIR LIGHTS NOR IS THERE A RECALL.THIS IS A COSTLY REPAIR AND A SAFETY ISSUE

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.

MY VEHICLE IS ONLY THREE YEARS OLD. THE RIGHT REAR LED TAILLIGHT HAS FAILED. THE TAILLIGHT NO LONGER WORKS. IT DOES NOT WORK WITH THE DAYTIME RUNNING LIGHTS OR WHEN YOU PRESS ON THE BRAKE. THIS IS A KNOWN ISSUE WITH THE 2016 GMC YUKONS. THE DEALERSHIP WANTS $900.00 TO REPLACE THE ENTIRE LIGHT HOUSING.

NHTSA ODI 11299081

BOTH TAIL LIGHTS AND BREAK LIGHTS HAVE STOPPED WORKING. THEY ARE MORE THAN $700 EACH AND GM KNOWS ABOUT THE PROBLEM AS THEY HAVE NO LIGHTS AVAILABLE, THEY ARE ON BACKORDER FOR WEEKS. YOU CAN FIND A FIX ONLINE BY RESOLDERING A METAL PIECE THAT CAN TEMPORARILY FIX THE PROBLEM.

MY DRIVER SIDE TAILLIGHT WENT OUT. DEALERSHIP REFUSED TO REPLACE AS MY 2016 WAS NO LONGER UNDER WARRANTY. HOWEVER, THE DEALERSHIP ADMITTED TO THE LARGE NUMBER OF LIGHTS THAT THEY HAVE HAD TO REPLACE. I HAD TO ORDER AND AFTERMARKET LIGHT TO REPLACE MYSELF. THE VERY NEXT DAY AFTER REPLACING THE LIGHT, MY PASSENGER SIDE TAILLIGHT IS NOW OUT. THIS IS UNACCEPTABLE!!! SO MANY COMPLAINTS REGARDING THIS ONLINE. THIS FIRST HAPPENED TO DRIVE SIDE AROUND JULY 2019.WE WERE FINALLY ABLE TO REPLACE THE LIGHT IN JAN 2020. THE PASSENGER TAILLIGHT WENT OUT 1/13/2020.

WE HAVE HAD OUR 2016 YUKON XL FOR ALMOST 2 YEARS. LAST YEAR WE STARTED EXPERIENCING EPISODES WHERE THE VEHICLE WILL SHIFT DOWN INTO REDUCED POWER MODE WITH P0090 AND P0091 AS THE FAULT CODES. WE HAVE BEEN WORKING WITH THE DEALER, BUT ONCE THE VEHICLE HAS BEEN TURNED OFF FOR ABOUT 20 MINUTES OR SO IT CLEARS AND LEAVES NO TRACE OF AN ISSUE. THIS IS EXTREMELY DANGEROUS AND RECENTLY SHIFTED INTO REDUCED POWER LEAVING US ONLY ABLE TO DRIVE 35 MILES PER HOUR. WE WERE ON THE HIGHWAY IN MARYLAND WITH CARS FLYING AROUND US AT ~80 MILES PER HOUR. WE HAD ALL OF OUR CHILDREN IN THE CAR AND WERE IN THE FAR LEFT LANE. THE REDUCED POWER MADE IT NEARLY IMPOSSIBLE TO GET TO THE RIGHT SHOULDER SAFELY. I HAVE A FRIEND WITH A NEW GMC SIERRA THAT HAS THE SAME ISSUE. HE DROPPED IT OFF AT HIS DEALER FOR 3 WEEKS AND RETURNED IT FINDING ANY ISSUES. THIS IS VERY DANGEROUS AND NEEDS TO BE ADDRESSED. ALL IT WILL TAKE IS SOMEONE DYING TO TURN IT INTO A CLASS ACTION LAWSUIT.

NHTSA ODI 11298664

MY REAR TAIL LIGHTS STOPPED WORKING AND THE DEALERSHIP IS CHARGING $800 TO REPLACE THE MODULE. PREVIOUSLY I HAD A 2016 YUKON XL AND THE SAME THING HAPPENED AROUND 40K MILES. MY SISTER-IN-LAW ALSO HAS A 2016 YUKON XL AND ONE OF HER TAIL LIGHTS DID THE SAME THING. AFTER SEARCHING ONLINE THIS SEEMS TO BE A COMMON PROBLEM WITH 2015 AND 2016 YUKON XL MODELS AND GM SHOULD BE REPLACING THESE PARTS AT NO COST TO THESE THOUSANDS OF PEOPLE EXPERIENCING THIS PROBLEM WHEN THE CAR ISN'T EVEN 5 YEARS OLD.

BRAKES WERE NOT 100% RESPONSIVE STARTING IN SUMMER 2019; VACUUM PUMP WAS REPLACED PURSUANT TO RECALL IN LATE 2019 AND SOFTWARE ERROR RELATED TO BRAKING WAS ADDRESSED BY DEALER IN JANUARY 2020. CUSTOMER STATED TO DEALER THAT BRAKES ARE STILL NOT 100% RESPONSIVE, AND THAT BRAKES WILL PULSE A FEW TIMES WHEN PRESSED AND BEFORE THE VEHICLE ACTUALLY STARTS TO STOP. DEALER REFUSED TO CONSIDER THAT EXISTING ISSUES WITH LAST TWO RECALLS IN 2019 RELATED TO BRAKES COULD BE CAUSING NON-RESPONSIVE BRAKES.

NHTSA ODI 11297728

RIGHT TAIL LIGHT WENT PUT, TOOK IT TO GET FIXED. THEY SAID IT WAS THE CIRCUIT BOARD AND I HAD TO PAY $900 TO GET IT FIXED. THE DEALERSHIP SAID THEY HAVE HAD A TON OF THE CIRCUIT BOARD REPLACEMENTS AND DIDN'T KNOW WHY GM DIDN'T DO A RECALL. NOW, MY LEFT SIDE CIRCUIT BOARD IS OUT AND NEEDS TO BE REPLACED.

NHTSA ODI 11297280

REAR LED TAILLIGHT WENT OUT OUR ONLY 3 YEAR OLD 2016 GMC DENALI. THIS EFFECTS THE STOP, TAIL, AND TURN LIGHTS. THESE LED LIGHTS ARE NOT REPAIRABLE AND THE WHOLE ASSEMBLY HAS TO BE REPLACED. GM CHARGES AN ASTRONOMICAL PRICE OF AROUND $700 FOR EACH SIDE. IT IS VERY HARD TO FIND ANY USED ONES AND ACCORDING TO PART DEALERS GM HAS A 'BOUNTY' ON ANY USED ONES TO TURN BACK IN. OBVIOUSLY GM IS AWARE OF THIS PROBLEM AND NEEDS TO ADDRESS IT AS NOT ONLY AS GOOD CUSTOMER RELATIONS BUT IT'S REALLY A SAFETY ISSUE AS WELL.
