2015 GMC Yukon Denali XL complaints

MY PASSENGER SIDE TAIL BRAKE LIGHT WORKS INCONSISTENTLY

THE TAIL LIGHTS ON BOTH SIDES ARE LED LIGHTS. THEY ARE WORKING INTERMITTENTLY. ONE SIDE WILL SOMETIMES COME BACK ON IF I BUMP IT WITH MY HAND. MY VEHICLE HAD LESS THAN 50,000 MILES ON IT WHEN THIS STARTED OCCURRING BUT WAS OUT OF WARRANTY. I HAVE BEEN TOLD THAT IT WILL COST APPROXIMATELY $1500 TO FIX. I HAVE ALSO BEEN TOLD BY THE DEALER THAT THIS IS A COMMEN PROBLEM WITH THE 2015 MODEL. I FEEL THAT THIS IS AN EXTREME SAFETY ISSUE AND SHOULD BE REPLACED BY GM THROUGH A RECALL. BECAUSE THE LIGHTS WORK INTERMITTENTLY, IT IS OBVIOUSLY A SHORT OR DEFECT OF SOME KIND.

AT 44K MILES ON THE VEHICLE, NOTICED THAT THE LEFT REAR BRAKE LIGHTS (LEDS) WERE NOT ILLUMINATING WHEN THE BRAKE WAS APPLIED, AT REST OR WHILE DRIVING. THIS INCLUDES BOTH THE TAIL LIGHTS AND BRAKE LIGHTS. PHYSICALLY TAPPING ON THE HOUSING LIGHTS THEM UP TEMPORARILY, BUT IT DOES NOT STAY LIT. DEALER WANTS OVER 700 DOLLARS TO REPLACE THE ENTIRE ASSEMBLY. DOING RESEARCH ONLINE SHOWS MANY MANY OTHER OWNERS WITH THESE LED TAIL LIGHT ASSEMBLYS WITH THE EXACT SAME ISSUE. THE PART IS DEFECTIVE, IN THAT THE CIRCUIT INSIDE THE ASSEMBLE BRAKES, AND THE LIGHTS WILL NOT LIGHT UP. THE LED BULBS THEMSELVES STILL WOULD WORK, IF THE CIRCUIT TO THEM WAS NOT DEFECTIVE. SOMEONE NEEDS TO STEP UP AND CALL OUT THE MANUFACTURE ON THIS ONE. ITS A MANUFACTURER DEFECT, NOT BAD BULBS! PLEASE HELP. HERE IS ONE FORUM THAT HAS MANY PEOPLE TALKING ABOUT IT.

RIGHT SIDE TAIL LIGHT IS NOT WORKING TRANSMISSION IS CLUNKS WHEN SELECTING DRIVE FROM REVERSE. WHEN ROLLING SLOW IN A PARKING LOT, SOMETIMES THE TRANSMISSION HAS A VERY HARSH CLUNK AS IF SOMEONE HAS HIT ME IN THE REAREND. THE STEERING COLUMN HAS A POPPING NOISE WHEN TURNING LEFT.

MY GMC YUKON XL VIBRATES BADLY AT ALL SPEEDS BUT INTENSIFIES AT SPEEDS BETWEEN 40-55. THE VIBRATION CAN BE FELT THROUGH THE WHOLE FRAME OF THE CAR. THE CABIN CREATES A THROBBIING SOUND, LIKE A HELICOPTER INSIDE THE CAR. THE STEERING WHEEL VIBRATES. THE CAR CONSUMES OIL AT AN ALARMING RATE WITH NO VISIBLE LEAKS OR NOTICABLE EXHAUST. THE CAR SURGES UNEXPECTEDLY SOMETHINES AROUND CORNERS OR BACKING OUT OF PARKING SPOTS. AND THE REAR "CLUNKS" WHEN ACCELERATING FROM A SLOW SPEED SUCH AS ONTO A HIGHWAY ENTRANCE RAMP. THE REARVIEW CAMERA A IS TOTALLY WORTHELSS IN LOW LIGHT LEVELS AND CANNOT BE USED FOR SAFE BACK UP OPERATIONS. DEALER HAS HAD THE CAR FOR OVER 50 DAYS AND HAS REPLACED THE TRANSMISSION, REPLACED THE TORQUE CONVERTER, HAS REPLACED THE STRUTS AND SHOCKS AND HAS CHANGED FLUISD AS PER GM INSTRUCTION. IN ALL THIS TIME AND OVER 6 VISITS, THEY CANNOT FIX AND HAVE TOLD ME THAT GM HAS SAID THIS IS THE "NEW NORMAL". IF THIS IS NORMAL, WHY DID THEY SPEND SO MUCH TO TRY AND FIX SOMETHIG THAT WAS NOT WRONG? THE DEALER ALSO TOLD ME THAT THE REAR VIEW CAMERA WILL NOT WORK PROPERLY BECUASE OF ALL OF THE FACTORY OPTIONS ON THE CAR AND THAT DEGRADES THE QUOALITY OF THE IMAGE. GM HAS NOT CONTACTED ME ALTHOUGH I HAVE REQUESTED THROUGH THE DEALER THAT THEY DO SO. I SEE THIS IS A COMMON PROBLEM WITH GMC CARS OF THIS YEARS MODEL. I WOUL DLIKE TO SEE ACTION TAKEN AGAINST GMC TO CORRECT THIS OR MAKE ME WHOLE.

WHILE IN MOTION MY VEHICLE SHUTS COMPLETELY OFF. THIS IS IN THE MIDDLE OF TRAFFIC AT TIMES. IT DISPLAYS WARNINGS THAT STABILITRACK HAS BEEN DISABLED AND SHUITS DOWN EVERYTHING ELECTRICAL. AT SOME POINTS IT DOESNT SHUT COMPLETELY DOWN, BUT INSTEAD HESITATES AND THEN PICKS BACK UP. THIS HAPPENS IN VARIOUS SITUATIONS WHETHER IT BE ON THE HIGHWAY, TURNING, OR DRIVING CITY ROADS.

LED BRAKE LIGHT ALREADY BURNT OUT AND ONLY 2 YEARS OLD. OVER $600 TO FIX A LIGHT THAT IS SUPPOSE TO HAVE A UNLIMITED LIFE....

ACTIVE FUEL MANAGEMENT SYSTEM IN 2015 GMC YUKON DENALI XL-- ENGINE WAS RUNNING IN TRAFFIC AND STALLED OUT AT INTERSECTION MAKING A TURN. DEALERSHIP DIAGNOSED AS BENT PUSH ROD, BROKEN VALVE SPRING, BROKEN LIFTER. THIS HAS BEEN LINKED TO FAULTY ACTIVE FUEL MANAGEMENT SYSTEM WITH GMC ENGINES. THERE IS AN ACTIVE SERVICE BULLETIN FROM GM CONCERNING THIS PROBLEM. UNDER EXISTING POWERTRAIN WARRANTY, GM AGREES TO FIX THE BROKEN ENGINE COMPONENTS, BUT WILL NOT ADDRESS THE UNDERLYING ROOT CAUSE OF THE PROBLEM, THE AFM SYSTEM. THE GM CUSTOMER SERVICE REP STATED THAT IT IS NOT GM'S CURRENT POLICY TO ADDRESS THE AFM SYSTEM EVEN THOUGH IT IS A KNOWN PROBLEM. THE DEALERSHIP SERVICE DEPARTMENT AGREES THIS IS THE PROBLEM. DOCUMENTATION ONLINE FROM OTHER CONSUMERS VALIDATES THAT THIS IS A WIDESPREAD ISSUE. IT IS A SAFETY CONCERN BECAUSE UNLESS THE AFM SYSTEM IS ADDRESSED, THERE IS A RISK THE ENGINE WILL FAIL IN TRAFFIC. I FEEL LIKE GM IS UNWILLING TO ADDRESS THIS ISSUES BECAUSE THERE IS NO EASY, CHEAP FIX AND THE PROBLEM IS SO WIDESPREAD IN ITS VEHICLES WITH AFM SYSTEMS. IT IS A POTENTIAL PUBLIC TRAFFIC SAFETY CONCERN AS THESE ENGINES AGE.

VEHICLE WAS MANUFACTURED MID 2014, 2015 MODEL, CURRENTLY HAS JUST OVER 52K MILES. DRIVERS SIDE TAILLIGHT IS BEING TEMPERAMENTAL; NO WARNING LIGHTS INSIDE TO INDICATE A FAILURE. WHEN YOU PRESS ON THE TAILLIGHT IT STILL ILLUMINATES, THERE ARE NO LEDS OUT, BUT TAILLIGHT AND BRAKE LIGHT WON'T ILLUMINATE. CALLED THE DEALERSHIP AND THEY'VE STATED IF FOUND FAULTY IT REQUIRES COMPLETE REPLACEMENT OF THE TAILLIGHT AND IT WAS QUOTED AT ROUGHLY $850 INSTALLED, WHICH SEEMS REALLY EXCESSIVE WHEN A TAILLIGHT GOES OUT.

THE BRAKE LIGHTS IN THIS VEHICLE ARE FAULTY. MY DRIVER SIDE WENT OUT IN JULY AND IN THE SAME MONTH MY PASSENGER SIDE WENT OUT. THE BULBS ARE NOT BURNED OUT AND IT HAS TO DO WITH THE WIRING. GMC WILL NOT COVER THE SECOND LIGHT OR PROVIDE COST ASSISTANCE BECAUSE I AM OUT OF WARRANTY DUE TO MILES.

MY STEERING WHEEL POPS WHEN TURNING IT. DEALER TRIED REPAIR, BUT CONTINUES TO POP. NOW OUT OF WARRANTY, AND WORSE THAN BEFORE. $1,000 CHARGE TO REPLACE THE UPPER BEARING.

1. WHILE DRIVING STEERING WHEEL WAS MAKING A CLICKING NOISE WHEN TURNING. DEALER REPLACED UPPER STEERING COLUMN BEARING AND TURN SIGNAL. THREE MONTHS LATER DEALER REPLACED STEERING COLUMN AGAIN DUE TO SAME ISSUE. 2. ONE MONTH LATER BOTH FRONT COIL SPRINGS WERE REPLACED. 3. WHEN REPLACED SPRINGS, DEALER FOUND THAT LEFT FRONT UPPER BALL JOINT WAS LOOSE SO REPLACED UPPER BALL JOINT AND UPPER CONTROL ARM. 4. AFTER REPLACING ABOVE MENTIONED PARTS, NOISE WAS STILL PRESENT WHEN DRIVING SO DEALER REPLACED BOTH LEFT AND RIGHT FRONT STRUTS. 5. THE FOLLOWING MONTH RIGHT FRONT STRUT WAS REPLACED AGAIN DUE TO NOISE WHILE DRIVING. 6. ONE MONTH AFTER THAT SERVICE THE RADIATOR BEGAN LEAKING WHILE ON THE ROAD AND THE DEALER REPLACED THE RADIATOR. 7. 07/12/2017 LEFT FRONT STRUT WAS REPLACED AGAIN. THIS IS THE 4TH STRUT PUT IN THIS VEHICLE. 8. 07/12/2017 A/C STOPPED WORKING. DEALER SAID IT NEEDS NEW CONDENSER WHICH IS ON BACK ORDER INDEFINITELY AT THIS POINT SO NOT ABLE TO FIX AT THIS TIME. THESE ISSUES HAPPENED OVER A PERIOD OF 18 MONTHS. NOT AT A SPECIFIC TIME. THE STEERING COLUMN IS STILL MAKING A CLICKING NOISE WHILE TURNING. WE HAVE TAKEN THE VEHICLE BACK, HOWEVER THE DEALER SAYS THEY ARE UNABLE TO DUPLICATE THE NOISE. IF THEY END UP REPLACING THE STEERING COLUMN AGAIN IT WILL BE THE THIRD TIME. THIS VEHICLE IS NOT TRUST WORTHY TO DRIVE LONG DISTANCES OR CROSS COUNTRY. VERY DISAPPOINTING FOR A $70,000 NEW VEHICLE.

A/C CONDENSER IS LEAKING. THE PART IS ON BACK ORDER FOR MONTHS. THIS PROBLEM NEEDS TO BE LOOKED AT AS A RECALL.

VEHICLE STARTED TO BLOW HOT AIR WHEN AIR CONDITIONER WAS ON. BROUGHT THIS IN TO GET IT FIXED TWICE AND LAST TIME WE WERE INFORMED THAT THERE IS A HOLE IN THE CONDENSER AND THAT GM IS TRYING TO FIND A MANUFACTURER FOR THE PART BUT HAVE NO TIMETABLE AS TO WHEN THE PART WILL BE AVAILABLE. WE ALSO CALLED GM AND THEY CONFIRMED THAT THERE IS AN ISSUE BUT HAVE NO TIMETABLE ON WHEN THIS WILL BE FIXED. THEY WERE WORKING WITH ONE MANUFACTURER THAT HASN'T BEEN ABLE TO PRODUCED THE PART SO NOW THEY ARE WORKING WITH ANOTHER MANUFACTURER. FOR THE SAFETY OF MY CHILDREN, THIS IS UNACCEPTABLE.

A/C STOPPED WORKING AND WAS TOLD IT WAS DUE TO BAD CONDENSER AND THE PART GETS DAMAGED WHERE IT BOLTS ONTO THE RADIATOR. WAS TOLD THAT A PART WOULD BE ORDERED BUT THERE IS NO ETA ON WHEN THE PART WILL BE DELIVERED DUE TO NATIONWIDE SHORTAGE OF PART DUE TO SO MANY PROBLEMS. ALSO, DEALER NOTIFIED ME THAT GM WAS ONLY ALLOWING ONE CONDENSER TO BE ORDERED PER VIN AS SUPPLY IS SO SHORT BECAUSE OF THE PROBLEM. AC DOESN'T WORK. CAN'T DRIVE WITH MY TWO CHILDREN AND DOG IN THE CAR WHEN THE TEMPERATURE IS OVER 80 DEGREES. SON HAS ASTHMA AND WE RELY ON THE AC TO BE WORKING.
