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

REAR PASSENGER BRAKE LIGHT STOP WORKING, VEHICLE IS ONLY 2 YEARS OLD. WE SHOULD NOT BE HAVING THIS ISSUE SO SOON OR AT ALL, SINCE LED LIGHTS NORMALLY DONT STOP WORKING. I ALSO LOOKED INTO FIXING IT AND ITS GONNA COST $700 DOLLARS. THIS IS RIDICULOUS!

BOTH REAR TAIL LIGHTS HAVE FAILED UNDER 40,000 MILES. DEFECTIVE! PLEASE RECALL!!!

NHTSA ODI 11133227

BOTH THE DRIVER AND PASSENGER BRAKE LIGHTS ARE NOT FUNCTIONING AT ALL. BECAUSE IT IS AN LED LAMP, THE ENTIRE TAIL LAMPS ASSEMBLY REQUIRES REPLACEMENT AT A SIGNIFICANT COST.

PROGRESSIVE INTERMITTENT BRAKE LIGHT FUNCTIONALITY THAT EVENTUALLY CULMINATED WITH COMPLETE INOPERABILITY; ONLY THE RIGHT/LEFT BRAKE LIGHT ASSEMBLIES ARE AFFECTED; REVERSE LAMPS OPERATE; UPPER CENTER BRAKE LIGHT FUNCTIONS NORMALLY; THIS IS A KNOWN PROBLEM WITH GMC BRAKE LIGHT ASSEMBLIES PER MULTIPLE FORUMS

GMC BRAKE LIGHT FAILURE - I OWN A 2016 GMC YUKON XL AND AFTER ABOUT 45,000 MILES THE BRAKE LIGHTS HAVE STARTED INTERMITTENTLY NOT WORKING. AFTER HAVING A GMC TECHNICIAN TELL ME THAT ITS A KNOWN ISSUE AND SEEING HUNDREDS OF OTHERS POSTS ONLINE, IT IS EVIDENT THAT THIS IS A VERY WIDESPREAD PROBLEM. I WAS NEARLY INVOLVED IN A REAR END CRASH ON THE FREEWAY BECAUSE THE DRIVER TOLD ME I DID NOT HAVE ANY BRAKE LIGHTS. THIS IS A SERIOUS SAFETY ISSUE AND GMC NEEDS TO CORRECT IT. THEY WANT ME TO PURCHASE 2 REPLACEMENT LIGHT UNITS AT 750.00 EACH.

WATER LEAK DUE TO BAD FRONT WINDSHIELD SEAL, WATER LEAK THROUGH GPS ANTENNA, FOUR WHEEL DRIVE MODULE WAS BAD, DVD PLAYER STOPPED WORKING, AND LASTLY A HORRIBLE VIBRATION THAT OCCURRED AROUND 77-83 MPH. TO THE POINT THE VEHICLE DID NOT FEEL SAFE TO HANDLE. TRIM ON THE B POST KEPT COMING LOOSE. THIS ALL OCCURRED IN OVER A YEARS PERIOD OF TIME. THIS WAS MY SECOND VEHICLE BECAUSE I TRADED IN MY 2015 TAHOE BECAUSE IT WAS HAVING MANY OF THE SAME ISSUES AND MORE. GM DID REPAIR ALL ISSUES OTHER THAN THE SHAKING, THEY WANTED ME TO BUY TIRES AND AFTER READING OTHER COMPLAINTS ON THE SHAKING I REFUSED, THE TIRES ONLY HAD 25,800ISH MILES ON THEM

ON 2/28/2018 I HAD JUST LEFT THE AIRPORT IN OAKLAND CA, APPROX 8:00PM. I STOP FOR GAS AT THE CHEVRON STATION ON 98TH AVE, AFTER FUELING, THE CAR WOULD NOT START. REMINDER, THIS IS A 2016 DENALI. I HAD A FEMALE ASSOCIATE WITH ME AND WE HAD AN APPOINTMENT IN SAN FRAMSICO AT 8:30PM. THE CAR HAD LOST ALL POWER AND TWO OTHER PEOPLE HELPED ME PUSH INTO ADJACENT PARKING SPACE. THE AREA IS KNOWN FOR HIGH CRIME, BASICALLY WE WERE EXTREMELY NERVOUS AND STRANDED. FORTUNATELY, WE WERE ABLE TO CONTACT AAA AND SET AN APPOINTMENT TO CHECK OUT THE CAR. WE UBERED TO OUR APPOINTMENT. THE FAILURE OF THE BATTERY LEFT US VUNRABLE AND WE BOTH FEARED FOR OUR SAFETY. THE NEXT DAY, THE LOCAL MECHANIC SAID THE BATTERY SHOULD HAVE LASTED A MINIMUM OF SEVEN YEARS. THEY FELT THE BATTERY WASN'T SUFFICIENT TO HANDLE THE ELECTRONICS THAT WERE BUILT INTO THIS CAR. THEREFORE, POTENTIALLY CREATING A MAJOR SAFETY CONCERN WITH ANY OWNER OF THIS VEHICLE. MY COMPLAINT HIGHLIGHTS THE POTENTIAL SAFETY IMPLICATIONS CAUSED BY THE MANUFACTURES DECISION TO REDUCE COST BY INSTALLING A BATTERY WITHOUT THE CAPACITY TO REASONABLY START THE VEHICLE AFTER ONLY TWO YEARS OF USE. I WOULD HOPE ALL OWNERS OF THIS MAKE AND MODEL ARE NOTIFIED OF THIS POSIBLITY. I CAN'T IMAGINE ANY OF MY FAMILY MEMBERS BEING EXPOSED TO THIS SITUATION. THANK YOU!

I PURCHASED A 2016 YUKON DENALI BRAND NEW FROM THE DEALER IN OCTOBER 2016. SINCE THIS TIME THE VEHICLE HAS BEEN IN THE SHOP 5 TIMES. THE FIRST TIME WAS DUE TO FRONT DRIVER SIDE DOOR NOT BEING FULLY ALIGNED WITH THE FRONT FENDER. THIS ISSUE WAS NOT RESOLVED AS THEY SAID IT WOULD "MOST LIKELY MESS THE VEHICLE UP FURTHER". IN FEBRUARY OF 2017 MY YUKON WENT BACK TO THE DEALER FOR SERVICE INVOLVING THE POWER RUNNING BOARDS NOT DEPLOYING AND CONTROL PANEL NOT ILLUMINATING. THE CONTROL PANEL WAS BLAMED ON A SOFTWARE UPDATE. WHILE AT THE DEALER THE SERVICE MANAGER STATED THAT "GM PUT OUT THIS SOFTWARE TOO EARLY". IN MAY 2017 THE REAR DVD PLAYER WENT BLANK AND STOPPED WORKING. THESE TWO ISSUES WERE BOTH COVERED UNDER WARRANTY. IN NOVEMBER 2017 THE RADIO STARTED TO "FREEZE" AND WOULDN'T CHANGE CHANNELS. I WAS TOLD THIS WAS A SOFTWARE UPDATE ISSUE AND I NEEDED A NEW HMI ($500) AND WILL NOT BE UNDER WARRANTY AS I NOW HAVE 40,000 MILES. IN DECEMBER 2017 MY YUKON WENT BACK TO THE SERVICE DEPARTMENT DUE TO AIR CONDITIONER FAILURE. AFTER REVIEWING ON THE INTERNET THIS SEEMS TO BE A COMMON PROBLEM FOR THIS VEHICLE. APPARENTLY, THERE WAS A SPECIAL BULLETIN THE CONSUMER ISN'T AWARE OF UNTIL IT BREAKS, SO IT WAS ALSO COVERED; HOWEVER THE BLOWER MOTOR ($377) THAT BROKE DUE TO THIS ISSUE WASN'T COVERED. I CONTACTED GM CUSTOMER SERVICE AND FILED A COMPLAINT WITH A SUPERVISOR. I WAS TOLD THERE IS NOTHING THEY CAN DO DUE TO MY YUKON BEING OUT OF WARRANTY, AND WHEN THEY BUILD THESE VEHICLES "THEY DO NOT KNOW HOW LONG PARTS WILL LAST". IN MY OPINION THIS IS UNACCEPTABLE ESPECIALLY FOR A $75,000 + VEHICLE THAT IS ONLY 2 YEARS REMOVED FROM THE MANUFACTURER. I HAVE OWNED 3 GM PRODUCTS (TAHOE, YUKON, AND NOW THIS VEHICLE) AND I WILL NEVER BUY ANOTHER GM PRODUCT.

ELECTRICAL ISSUES: WHILE DRIVING THE INFORMATION PANEL GO'S BLANK. WE HAVE EXPERIENCED THIS TWICE WHILE DRIVING, WE LOSE THE SPEEDOMETER, TECH, AND EVERYTHING ON THE DISPLAY PANEL. RADIO, SKIPS CHANNELS EVEN AFTER THE SWITCH WAS REPLACED. DRIVE TRAIN: DOWN SHIFTS ABRUPTLY WHILE ACCELERATING ONTO INTERSTATE ON RAMPS, EITHER LUNGING FORWARD OR LUNGING BACKWARD. BEEN IN THE GM SHOP THREE TIME TO TRY AND FIX ISSUE. THERE HAVE BEEN BULLETINS ISSUED TO TRY AND FIX WITHOUT SUCCESS TO-DATE. THEY ARE AWARE THAT IS A PROBLEM, BECAUSE FORD AND GM ON THE 2018'S, I WAS TOLD BY THE SALES PERSONS THAT THIS ISSUE WAS FIXED. I AM AWARE OF THE CHEVY TRANSMISSION ISSUE AND I AM CONCERNED THAT THIS MAYBE A SIMILAR SAFETY CONCERN. AS FAR AS I KNOW THE TRANSMISSION HAS NOT JUMPED OUT OF GEAR ON ITS OWN. I AM LOOKING AT A SHOP TICKET AND THEY ARE CALLING THE ISSUE A SHUTTER DURING TORQUE CONVERTER LOCKS UP.

SAID VEHICLE MAINTAINS A DEFECT THAT SUBSTANTIALLY IMPAIRS ITS USE AND SAFETY AND DOES NOT CONFORM TO APPLICABLE WARRANTY PROVISIONS. THE VEHICLE'S INFOTAINMENT/INTELLILINK SYSTEM BECAME COMPLETELY DYSFUNCTIONAL ON JANUARY 14, 2017, AND SAID CONDITION WAS REPORTED TO GMC'S INFOTAINMENT CUSTOMER SUPPORT VIA TELEPHONE ON THIS DATE (SERVICE REQUEST NUMBER: 8-2666432517). AS GMC'S INFOTAINMENT CUSTOMER SUPPORT REPRESENTATIVE WAS NOT ABLE TO ASSIST WITH THE ISSUE, A SERVICE APPOINTMENT WAS SCHEDULED FOR JANUARY 17, 2017 AT AN AUTHORIZED GMC SERVICE CENTER FOR REPAIR OF THE INTELLILINK SYSTEM ON JANUARY 17, 2017. THE INTELLILINK SYSTEM WAS NOT REPAIRED OR RENDERED FUNCTIONAL BY GMC AND/OR ITS AUTHORIZED DEALER/SERVICE CENTER ON JANUARY 17, 2017. GMC PERSONNEL HAVE STATED THAT THE NECESSARY PART TO REPAIR THE DISABLED INTELLILINK SYSTEM IS ON BACK ORDER AND COULD TAKE UP TO TEN WEEKS TO BE DELIVERED TO THE DEALERSHIP.

BOUGHT SUV 6/25/2016 THE SAME WEEKEND THE ENGINE TURNS OFF AFTER A LEFT OR RIGHT TURN :IT HAS HAPPENED 3 TIMES SO FAR. 4 WEEK OLD 2016 YUKON DENALI XL, HAS STALLED 3 TIMES IN LAST 4 WEEKS, ENGINE CUTS OFF AFTER A LEFT OR A RIGHT TURN ONLY AFTER A SHORT DRIVE OUT OF HOME. THE SUV HAS TO BE RESTARTED! COULD HAVE EASILY HAD AN ACCIDENT OR WORSE. I TOOK IT TO THE WESTPOINT GMC DEALER, 3 TIMES. 1ST TWO TIMES, ALL OF SERVICE DEPTARTMENT COULD NOT DIAGNOSE THE PROBLEM. TODAY, AFTER A STALL, I CALLED ONSTAR, WHO RAN A DIAGNOSTICS TEST,BUT ONSTAR FOUND NOTHING OF VALUE , I LEFT IT AT DEALERSHIP AND CONTACTED DISTRICT MGR. MATT TILLSON . I WAS TOLD THAT THEY WOULD ESCALATE THE ISSUE. I DID TELL DEALER THAT GMC AND DEALERSHIP WOULD BE AT FAULT IF VEHICLE IS INVOLVED IN AN ACCIDENT AND STALLS NOR STOPS WHILE I AM DRIVING. I DID NOT WANT THE VEHICLE BACK WITHOUT THE PROBLEM HAVING BEEN FIXED. ITS DAY 6 TODAY. I NEED TO MAKE IT ABSOLUTELY CLEAR, I WILL NOT TAKE THE VEHICLE BACK UNTILL THE PROBLEM HAS BEEN DIAGNOSED, AND FIXED. I DO NOT WANT ME OR MY FAMILY OR GM SERVICE EMPLOYEE INJURED, OR WORSE, OR TO BE INVOLVED WITH A POSSIBLE ACCIDENT IN MY GMC YUKON DENALI XL. A FIELD SERVICE ENGINEER SHOULD HAVE BEEN ON THIS CASE ALREADY ! WILL IT TAKE AN ACCIDENT, OR INJURY BEFORE SOMEONE GETS ASSIGNED?
