What 977 owners told NHTSA about the 2015 GMC Yukon Denali Xl 1500

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.

BRAKE LIGHT STOPPED WORKING, GMC WANTS TO REPLACE THE WHOLE ASSEMBLY FOR $800. MY WARRANTY HAS EXPIRED BUT I THINK GMC SHOULD HAVE AWAY TO REPAIR THE LIGHT INSTEAD OF REPLACING THE WHOLE ASSEMBLY. A RECALL ON THIS SHADY WAY OF GETTING THE CONSUMER HARD EARNED MONEY. BECAUSE IT SHOULD LAST LONGER. I CAN'T DRIVE MY CAR IN FEAR OF GETTING A TICKET. PLEASE HELP

LED BRAKE LIGHT IS FAULTY. DEALERSHIP WANTS OVER $800 FOR REPAIR OF SINGLE LIGHT. SEEMS TO BE A KNOWN PROBLEM FOR THIS MAKE AND MODEL.

NHTSA ODI 11099426

THE VEHICLE HAS UNDER 40,000 MILES AND THE BRAKE LIGHTS HAVE FAILED. THESE ARE LED TYPE BRAKE LIGHTS SO THEY SHOULD LAST MUCH LONGER. YOU CAN NOT REPLACE THE INDIVIDUAL BULBS. YOU MUST REPLACE THE WHOLE TAIL LIGHT ASSEMBLY AT THE COST OF $750 EACH. A WARNING ON THE DASH NEVER APPEARED TO NOTIFY ME THAT THE BRAKE LIGHT WAS NOT FUNCTIONING.

TL* THE CONTACT OWNS A 2015 GMC YUKON DENALI. WHILE THE VEHICLE WAS STATIONARY, WATER ENTERED THE CABIN OF THE VEHICLE THROUGH THE HIGH FREQUENCY ANTENNA SEAL. IN ADDITION, THE CONTACT STATED THAT THE COMPUTER SYSTEM HAD AN ELECTRICAL MALFUNCTION AND THE VEHICLE'S BRAKES ENGAGED WITHOUT WARNING. DIXIE BUICK GMC IN FORT MYERS, FLORIDA WAS MADE AWARE OF THE FAILURE AND DIAGNOSED THAT THE HIGH FREQUENCY ANTENNA NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 76,000. THE VIN WAS NOT AVAILABLE.

NHTSA ODI 11099074

BOTH BRAKE LIGHTS FAILED WITHIN WEEKS OF EACH OTHER - AROUND 60K MILES. FAULTY LED CIRCUIT BOARDS. LIGHT ASSEMBLIES ARE NOT REPAIRABLE BY DEALERSHIP. NEW ASSEMBLY OVER $500 EACH. GM TAKES NO RESPONSIBILITY IN RESOLVING THE ISSUE. UNACCEPTABLE! NO MORE GMS FOR MY FAMILY! .. AND THAT INCLUDES CHEVY.

TAIL LIGHT HAS BEEN FLICKERING FOR MONTHS AND NOW IS OUT. GMC WILL NOT FIX BECAUSE I AM 4 MONTHS OUT OF WARRANTY. I ONLY HAVE 18,000 MILES ON MY YUKON.

NHTSA ODI 11099093

VEHICLE FRONT HEADLIGHT AND TAILLIGHT LEDS ARE OUT. THREE OUT OF THE FOUR LIGHTS HAVE GONE OUT IN THE LAST MONTH.

NHTSA ODI 11098630

FAULTY BRAKE LIGHTS. GOES OUT INTERMITTENTLY AND THEN STOPS WORKING ALTOGETHER. CANNOT BE FIXED OR REPAIRED WHETHER IT IS ONE LED LIGHT OR MANY- THE WHOLE LED DISPLAY IS FAULTY AND STOPS WORKING. DEALER WAS GOING TO CHARGE $750 TO FIX- FOR JUST 1 REAR BRAKE LIGHT. NOT HAVING FULLY FUNCTIONING BRAKE LIGHTS ON A 3 YEAR OLD CAR IS UNACCEPTABLE AND SHOULD BE UNDER RECALL- IT'S A SAFETY ISSUE AND OBVIOUSLY A FAULTY PART WHEN THERE ARE NUMEROUS COMPLAINTS AND BLOG POSTS ABOUT THE SAME ISSUE.

NHTSA ODI 11098680

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.

TL* THE CONTACT OWNS A 2015 GMC YUKON DENALI. THE CONTACT STATED THAT THE BRAKE AND TAIL LIGHTS FAILED TO ILLUMINATE SPORADICALLY. THE VEHICLE WAS TAKEN TO WELD COUNTY GARAGE BUICK GMC (2699 47TH AVE, GREELEY, CO 80634, (970) 352-1313) WHERE IT WAS DIAGNOSED THAT THE BRAKE LIGHTS NEEDED TO BE REPLACED.

I'VE EXPERIENCED 2 POWER STEERING FAILURES IN THE LAST 6 MONTHS. FIRST, THE EPS FAILED (WHICH WAS RECALLED FOR MANY OF THE SAME MODEL--BUT NOT MINE) WHICH I REPLACED. NOW, POWER STEERING FAILED AGAIN, THIS TIME THE STEERING GEAR PER THE DEALERSHIP. THIS IS A SAFETY HAZARD! WITH THE MOST RECENT FAILURE, IF YOUR HANDS ARE NOT GRASPING THE STEERING WHEEL FIRMLY, THE CAR WILL VEER SHARPLY TO EITHER THE RIGHT OR LEFT. AND STEERING THIS BEAST WITH NO POWER STEERING IS NEARLY IMPOSSIBLE. MANY DRIVERS WOULD NOT BE ABLE TO OVERPOWER THE DEAD ELECTRIC STEERING SYSTEM. THE FIRST WARNING CAME AS LOUD SCREECHING SOUNDS FROM THE STEERING AT LOW SPEED. IT FELT AS THOUGH THE POWER STEERING MOTOR WAS INTERMITTENT, AND "JOLTING" THE STEERING WHEEL. THE SCREECHING STOPPED AT SPEED, BUT THE JITTERING/JOLTING OF THE ELECTRIC SYSTEM CONTINUED. THIS IS A SERIOUS MALFUNCTION, ESPECIALLY WITH SO FEW MILES ON THE VEHICLE.

THERE IS A WATER LEAK IN THE ROOF, ON THE DRIVER SIDE, RIGHT ABOVE THE A-PILLAR. THIS HAS HAPPENED ON MULTIPLE OCCASIONS DURING A HEAVY RAIN STORM. THE LEAK OCCURS REGARDLESS OF WHETHER OR NOT THE VEHICLE IS IN MOTION. AFTER TAKING IT TO THE DEALERSHIP FOR SERVICE, I WAS INFORMED THERE WAS A MANUFACTURER DEFECT WHICH COULD CAUSE SOME GAPPING IN THE VEHICLE BODY ROOF DITCH DRIVER SIDE, WHICH MAY ALLOW WATER TO LEAK THROUGH. I AM CONCERNED FOR MY FAMILY'S SAFETY AS THIS SITUATION COULD CREATE MOLD AND MILDEW IN THE INTERIOR LINER. ALSO, IT COULD POTENTIALLY LEAD TO A VERY DANGEROUS SITUATION IF THE GAPS/VOIDS IN THE BODY BECOME LARGER, ALLOWING WATER TO LEAK THROUGH AT A GREATER VELOCITY DURING HIGH SPEEDS OR ON THE FREEWAY. I WAS ALSO INFORMED THAT THIS IS A VERY COMMON ISSUE ON MULTIPLE VEHICLES FROM GM DURING THE SELECTED MODEL YEAR. DEALER ATTEMPTED TO SERVICE VEHICLE MULTIPLE TIMES BUT THERE IS STILL A WATER LEAK.

I WAS DRIVING DOWN THE ROAD AND SOMEONE CLEARLY (DUE TO THE LOUD SCREECHING OF THE TIRES) ALMOST REAR ENDED ME. THANKFULLY THEY WERE ABLE TO STOP JUST BEFORE HITTING MY VEHICLE. HE CAUGHT ME AT A STOP LIGHT AND INFORMED ME THAT BOTH OF MY BRAKE LIGHTS WERE OUT UNBEKNOWNST TO ME. I HAVE SINCE TAKEN THE VEHICLE TO THE DEALERSHIP, BUT THERE IS AN ISSUE WITH THE BRAKE LIGHT SYSTEM/PARTS FOR THIS VEHICLE. THE BRAKE LIGHT WILL WORK SPORADICALLY (WITHOUT ANY KNOWLEDGE OF AN ISSUE). THE MANUFACTURER HAD TO HAVE KNOWN THERE WAS AN ISSUE WITH THIS PART DUE TO THE OWNER'S MANUAL EVEN STATING "CONTACT GMC DEALERSHIP" WITHOUT GIVING ANY TROUBLESHOOTING ADVISE ON THE LIGHT. THE PART IS ~$650 TO REPLACE, BOTH OF MY BRAKE/TAIL LIGHTS HAVE GONE OUT WITHIN A 3 WEEK PERIOD OF EACH OTHER AND THE DEALERSHIP DIDN'T SEEM SURPRISED AT ALL OF THIS ISSUE.

NHTSA ODI 11096470

THE LED BRAKE LIGHTS FAIL DUE TO A MANUFACTURING ISSUE. IN LESS THAN 3 YEARS AND 40,000 MILES THE VEHICLE HAS GONE THROUGH 3 LED BRAKE LIGHT ASSEMBLIES. THERE IS NO WARNING WHEN THEY FAIL.

OUR 2015 YUKON DENALI HAS 38,200 MILES ON IT AND THE AIR CONDITIONING BLOWS HOT AIR. WAS TOLD MAY OR MAY NOT BE COVERED BY WARRANTY. MAY COST OVER $1,000 TO REPAIR. TOLD IT MAY WOULD BE A 6 HOUR REPAIR. CANNOT BELIEVE WE ARE HAVING THIS ISSUE LIKE SO MANY OTHER PEOPLE ON A $75,000 VEHICLE.SHOULD HAVE BEEN A RECALL ISSUED.

I WAS DRIVING ON HEAVILY-CONGESTED I-66 EASTBOUND IN THE DC METRO AREA (NORTHERN VIRGINIA) AT 70MPH. MY VEHICLE ALERTS ME WITH CHIME, SO I LOOK DOWN AT THE COMMUNICATION CENTER. I SEE AN ALERT THAT SAYS: SERVICE POWER STEERING ASSIST. I DECREASE MY SPEED AND SAFELY PULL OVER TO THE RIGHT SHOULDER. I TURN OFF MY VEHICLE TO SEE IF THE ISSUE WOULD RESET. I TURNED IT BACK ON, AND IT DID NOT. I CALL MY HUSBAND TO ALERT HIM OF THE ISSUE. I SAFELY REENTERED THE HIGHWAY, AND IT TOOK ALL MY MIGHT TO GET MY VEHICLE BACK ON THE ROAD. I ARRIVED AT WORK AND COULD BARELY STEER TO PARK MY VEHICLE. I CALLED MY DEALER TO LET THEM KNOW WHAT HAPPENED. HE LOOKED UP MY TRUCK BY VIN AND SAID THERE WAS NO RECALL ON IT; HOWEVER, THERE IS A RECALL FOR THE SAME ISSUE ON OTHER VEHICLES IDENTICAL TO MINE. APPARENTLY, THERE IS AN ISSUE WITH THIS PART ON MORE THAN THE VINS THAT ARE CURRENTLY LISTED, AND I WOULD LIKE TO GET THIS ISSUE RESOLVED ASAP. I AM HOPING THAT THE SAME THING WITH MY A/C CONDENSER DOES NOT HAPPEN: I PAID $1,000 AND HAD TO WAIT 3 MONTHS TO GET IT FIXED BECAUSE THE PART WAS ON BACKORDER, AND MONTHS LATER, I RECEIVED A LETTER IN THE MAIL SAYING THAT THERE IS AN ISSUE WITH THE PART AND GM WOULD FIX IT -- WELL AFTER THE FACT -- AND THAT SAME ISSUE AFFECTED SO MANY PEOPLE. I WILL ADMIT, THIS IS THE VERY LAST GM VEHICLE I WILL PURCHASE IF I HAVE TO COME OUT OF POCKET FOR THIS POWER STEERING ASSIST ISSUE. SOMETIMES I WONDER IF CERTAIN PERSONAL DEMOGRAPHICS ARE TIED TO THESE VINS AFTER A SALE. RECALL NUMBER 14V719000 RECALL DATE 11/10/2014 COMPONENT STEERING:ELECTRIC POWER ASSIST SYSTEM

TL* THE CONTACT OWNS A 2015 GMC YUKON. THE CONTACT STATED THAT THE VENT CONTROL FUNCTION SUDDENLY FAILED TO WORK, WHICH PREVENTED THE AIR CONDITIONING AND HEAT FROM WORKING. THE DEALER (SUNRISE BUICK GMC CHEVROLET AT COLLIERVILLE, 4605 S HOUSTON LEVEE RD, COLLIERVILLE, TN 38017, (888) 484-2878) INSPECTED THE VEHICLE AND STATED THAT THE CONDENSER FAILED AND THE PART WAS ON A NATIONAL BACKORDER. THE DEALER STATED THAT THE CONDENSER WAS ENGINEERED INCORRECTLY AND SHOOK AND RATTLED, WHICH CAUSED A CRACK THAT SPLIT THE CONDENSER. THE CONTACT STATED THAT THE MANUFACTURER ONLY PROVIDED A WARRANTY EXTENSION FROM 36,000 TO 60,000 MILES, BUT HAD NOT ISSUED A RECALL TO PROVIDE A REMEDY. THE CONTACT CORRESPONDED WITH THE MANUFACTURER BY EMAIL AND PHONE AND WAS INFORMED THAT THEY WOULD PROVIDE A FOLLOW-UP RESPONSE. THE CONTACT HAD BEEN WAITING FOR A RESPONSE FOR MONTHS. THE APPROXIMATE FAILURE MILEAGE WAS 70,000.

DEFECTIVE TAIL LIGHTS AND HEADLIGHTS.

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.

THE SHOULDER STRAPS ON THE 2 OUTBOARD 2ND ROW SEAT BELTS ARE FRAYED. I TOOK THE VEHICLE TO MY GMC DEALER TODAY AND HE INFORMED ME THAT SEAT BELTS ARE ONLY COVERED BY THE 36 MONTH/36000 MILE WARRANTY, I WAS SHOCKED TO HEAR THIS. MY VEHICLE HAS 57626 MILES ON IT. I BELIEVE THE DESIGN OF THE SEAT BELT IS FAULTY. WHAT IS OBVIOUSLY OCCURRING IS THE SEAT BELT BUCKLE IS RUBBING AGAINST AND THROUGH THE SHOULDER STRAP WHEN THE BELT IS IN THE RETRACTED POSITION. I AM CONCERNED ABOUT THE INTEGRITY OF THE BELTS, BUT I CONTEND THAT GMC SHOULD BE RESPONSIBLE TO CORRECT A FAULTY DESIGN. I HIGHLY DOUBT THIS CONDITION IS UNIQUE TO MY VEHICLE. I HAVE ATTACHED 2 PHOTOS OF THE PASSENGER SIDE BELT. THE BELT ON THE DRIVER'S SIDE HAS THE IDENTICAL CONDITION. THANK YOU.
