2015 GMC YUKON Electrical System Problems

ALL LED LIGHTS HAVE WENT OUT ON RIGHT SIDE, AS WELL AS BREAK LIGHTS. THIS IS A KNOW ISSUE TO GMC, AND YET THEY WILL NOT CORRECT IT. MY QUOTE TO HAVE IT FIXED WAS 2493.00 FROM LOCAL DEALERSHIP. THAT IS CRAZY. LED LIGHTS SHOULD LAST A WHOLE LOT LONGER THAN THIS. ALSO CONDENSATION IS IN THE FRONT HEADLIGHT WITH NO HOLES OR CRACKS. IF THIS HAPPENS WITH HOUSE WINDOWS, THEY ARE REPLACED BY THE MANUFACTURER. THERE ARE SO MANY COMPLAINTS, I WILL ALSO BE CONTACTING THE BETTER BUSINESS BUREAU. GMC KNOWS THERE IS A PROBLEM WITH THESE MODELS.

WIRING TO RADIATOR FAN CAUGHT ON FIRE. I WAS DRIVING THE CAR WHEN I SMELLED SMOKE. WHEN I PULLED OVER SMOKE WAS COMING FROM THE HOOD I OPENED THE HOOD AND THERE WAS OPEN FLAMES ON THE FAN WIRING WIRING.

WE OWN A 2015 GMC YUKON WITH ONLY 51,000 MILES ON IT. THE REAR TAILLIGHTS ARE BOTH INTERMITTENT. SOMETIMES THEY WORK, SOMETIMES THEY DON'T. I RECENTLY TOOK THE VEHICLE INTO THE DEALERSHIP FOR SERVICE AND THEY SAID REPLACEMENT OF THE ENTIRE LIGHT WAS THE ONLY WAY TO FIX THE ISSUE. THEY ACKNOWLEDGED THAT THIS IS A KNOWN ISSUE AND THAT THEY HAVE SERVICED MANY VEHICLES WITH THE SAME ISSUE. THE SERVICE PERSON ADVISED THAT THERE IS A CIRCUIT THAT OVER TIME BREAKS AND THE CONNECTION BECOMES LOOSE. WHEN THE METAL TOUCHES AND A COMPLETE CIRCUIT IS MADE, THE LIGHT WILL TURN ON. WHEN IT DOESN'T TOUCH (FAULTY), THE TAILLIGHT AND BRAKE LIGHTS WILL NOT ILLUMINATE. THIS IS A MAJOR SAFETY HAZARD. A SIMPLE INTERNET SEARCH SHOWS THAT THIS ISSUE IS VERY COMMON AND GM DOESN'T APPEAR TO BE DOING ANYTHING TO ADDRESS IT. BECAUSE IT INVOLVES THE BRAKE LIGHTS, THIS...

MY TAILLIGHT STOPED WORKING. WHEN I TURN MY HEADLIGHTS ON IT WONT TURN ON OR WHEN I APPLY MY BRAKES. I SEARCHED THE INTERNET(FACEBOOK AND FOURM SITES) AND FOUND THOUSAND AND THOUSAND OF PEOPLE HAVING THE SAME ISSUES. THE BRAKE LIGHT/RUNNING LIGHT IS NOT A LIGHT BULB LIKE MOST CARS THAT YOU CAN JUST REPLACE WHEN IT GOES OUT. ITS LED.SO YOU HAVE TO REPLACE THE WHOLE ENTIRE LIGHT ASSEMBLY AND IT WAS OVER $800. LED ARE SUPPOSED TO HAVE A LONG LIFE BEFORE THEY GO OUT.... THIS IS ONLY A 2015 I MEAN COME ON. SO I HAD TO DRIVE IN THE DARK AND DURING THIS RAIN STORM ON FREEWAY AND REGULAR STREETS WITH NO BRAKE OR RUNNING LIGHTS WHICH I S EXTREMELY DANGEROUS. THIS IS A FAMILY VEHICLE I DRIVE MY KIDS IN THIS CAR. THIS CANT KEEP HAPPENING. I ALSO READ THAT MULTIPLE PEOPLE SAID ONCE THEY...

THE VEHICLE'S TAIL LIGHT ASSEMBLY ON BOTH THE DRIVERS AND PASSENGER'S SIDES ARE DEFECTIVE. THE SOLDER DOES NOT HOLD AND THE VEHICLE'S BRAKE LIGHTS AND RUNNING LIGHTS FAIL INTERMITTENTLY. THE DRIVER IS TOTALLY UNAWARE OF THIS MAJOR ISSUE THAT THE BRAKE LIGHTS ARE NOT WORKING. IN RESEARCHING THIS PROBLEM ON THE INTERNET THERE ARE NUMEROUS CUSTOMERS OF GMC'S YUKON'S AND DENALI'S WHO ARE EXPERIENCING THE SAFETY PROBLEM. I REALIZED THE PROBLEM WHEN ANOTHER MOTORIST ALMOST STRUCK THE BACK OF MY VEHICLE BECAUSE THERE WERE NOT BRAKE LIGHTS AT ALL. THE VEHICLE WAS TRAVELING AND BOTH BRAKE LIGHTS FAILED. THE SIGNAL LIGHTS WILL STILL WORK.

THE REAR TAILLIGHT WORKS INTERMITTENTLY. I HAVE REPORTED IT TO THE DEALERSHIP AND THE ONLY FIX IS TO REPLACE THE HOUSING UNIT AT $1500. IT HAS BEEN REPORTED AND IS A KNOWN PROBLEM WITH GMC.

I HAVE HAD AN ON-GOING ISSUE WITH THE STEERING, ELECTRICAL AND POWER STEERING AND STABILITY CONTROL. I HAVE HAD REPEATED ISSUES WITH THE STABILITY CONTROL TURNING OFF, SUDDEN DROP IN ELECTRICAL POWER, THE STEERING WHEEL GETS VIOLENTLY YANKED OUT OF YOUR HANDS AND SOMETIME THE CAR COMPLETELY CUTS OFF. FORTUNATELY MOST HAVE BEEN AT SLOW SPEEDS OR ELSE THE CAR WOULD HAVE FLIPPED. IT IS THE EXACT SAME ISSUE OTHER MODELS HAVE BEEN RECALLED FOR BUT MY VIN IS NOT INCLUDED IN THAT RECALL. I AM AFRAID OF THIS ISSUE KILLING ME OR MY LOVED ONES SHOULD IT HAPPEN AT SPEED OR LEAVE US STUCK IN FRONT OF ON COMING TRAFFIC. ACCORDING TO MY DEALER THIS IS AN ISSUE THE MANUFACTURE HAS KNOW ABOUT FOR A WHILE. *TR

2015 YUKON PASSENGER LED TAIL LIGHT HAS FAILED. VEHICLE IS ONLY 3 YEARS OLD, AND IN ADDITION TO THE TAIL LIGHT FAILURE, HAVE HAD 3 AIR CONDITIONING SYSTEM FAILURES TO DATE. I DON'T KNOW HOW LONG THE TAIL LIGHT HAS BEEN INOPERABLE AS THERE WAS NO WARNING OR INDICATOR TO NOTIFY THE DRIVER OF A TAIL LIGHT PROBLEM. I ONLY DISCOVERED THIS PROBLEM WHILE FOLLOWING MY WIFE IN ANOTHER VEHICLE AS SHE WAS DRIVING THE YUKON. LOOKING AT THE COMPLAINTS LODGED ON BOTH ISSUES, I'M BEGINNING TO SERIOUSLY QUESTION GM'S RELIABILITY AND WILLINGNESS TO STAND BEHIND THEIR VEHICLE AND PARTS. ALWAYS THOUGHT LEDS WERE MORE RELIABLE, BUT LOOKING AT THE NUMBER OF COMPLAINTS LODGED, MY ASSUMPTIONS ARE APPARENTLY WRONG. A SIMPLE GOOGLE SEARCH ON YUKON TAIL LIGHT REPAIR ALSO SHOWS A COTTAGE INDUSTRY IN REPAIRING THESE LED TAIL LIGHTS HAS POPPED UP, WHICH INDICATES A SIGNIFICANT PROBLEM WITH THE DESIGN...

HAD RIGHT BRAKE LIGHT REPLACED IN WARRANTY. THE LEFT REAR IS NOW OUT. THIS IS A DRIVING SAFETY ISSUE FM SHOULD BE RESPONSIBLE FOR

THE REAR RIGHT TAIL LIGHT DON'T WORK PROPERLY HAS AN INTERMITTENT PROBLEM SOMETIMES WORK SOMETIME DON'T. DEALER TOLD ME CAN'T BE COVER UNDER WARRANTY, BECAUSE WAS EXPIRED. I'M AFRAID MAY BOTH TAIL LIGHT STOP WORKING AND GET REAR ENDED. GMC SHOULD DO SOMETHING, BECAUSE IS THEY PROBLEMS I SAW ON THOSE SUV

THE RIGHT REAR BRAKE LIGHT AND RUNNING LIGHT HAS GONE OUT. APPEARS TO BE A COMMON PROBLEM. YOU CAN'T REPLACE THE BULB LIKE OLDER CARS. YOU NEED TO REPLACE THE WHOLE BRAKE ASSEMBLY FOR $700!!! GM KNOWS ABOUT THE COMMON ISSUE BUT IS NOT COVERING IT.

BRAKE LIGHTS TAIL LIGHTS QUIT WORKING

WHEN USING STEERING TO TURN AROUND, TURN INTO A PARKING SPACE OR BACK IN, 'PARKING ASSIST OFF' SHOW UP ON THE INSTRUMENT PANEL, THEN THE STEERING WHEELS LOCKS AND THE CAR TURNS OFF WHILE STILL ENGAGED IN DRIVE. SOMETIMES 'BRAKE ASSIST' COMES ON FIRST. EXTREMELY DANGEROUS. WHEN THIS HAPPENS, UNABLE TO TURN STEERING WHEEL. CAR SHUTS DOWN AND DOORS LOCK. I HAVE TO PUT IT IN PARK AND RESTART THE CAR. SOMETIMES IT DOES IT MORE THAN ONCE AFTER RESTARTING THE CAR. I HAVE TAKEN IT TO A GMC DEALER FOR EVALUATION AND REPAIR. HAS HAPPENED AT LEAST 6 DIFFERENT TIMES. WHEN DRIVING, I AM ALWAYS AFRAID TO MAKE SHARP TURNS. HOWEVER, IT HAS ONLY HAPPENED AT SLOW SPEEDS WHEN TRYING TO TURN IN TO A DRIVEWAY OR TURN AROUND SUCH AS IN A PARKING LOT. *DT CONSUMER STATED AFTER TAKING MY CAR TO GMC DEALER AND BEING TOLD MY...

TL* THE CONTACT OWNS A 2015 GMC YUKON. WHILE DRIVING 65 MPH, THE BRAKE PEDAL WAS DEPRESSED, BUT THE BRAKE LIGHTS, TAIL LIGHTS, AND THE INTERIOR REAR BRAKE LIGHT FLICKERED. THE VEHICLE WAS TAKEN TO DELANO CHEVROLET BUICK GMC (600 1ST AVE, DELANO, CA 93215, 661-735-4974) TO BE DIAGNOSED AND REPAIRED. THE DIAGNOSIS RESULTS WERE UNAVAILABLE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 92,000.

REAR TAIL LIGHT NOT WORKING

TAIL LIGHT LED STOPPED WORKING. CONNECTION FAILED

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.

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...

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.

THERE SEEMS TO BE A PROBLEM WITH THE TAIL LIGHT ASSEMBLIES ON THE YUKON PRODUCT. THE TAIL LIGHT WILL STOP WORKING AND IT WILL NOT GIVE A WARNING THAT IT HAS GONE OUT. THE ASSEMBLY IS $600 TO REPLACE AND WE HAVE HAD TO REPLACE BOTH. I AM WORRIED THAT THEY WILL FAIL AGAIN AND I WILL BE FORCED TO REPLACE THEM AGAIN. I HAVE BEEN WATCHING OTHER VEHICLES LIKE MINE AND HAVE NOTICED THAT OTHER VEHICLES SUFFER THE SAME PROBLEM. IN SMALL TALK WITH THE DEALER, THE SERVICE ADVISORS ACKNOWLEDGED THAT IT IS A PROBLEM AND EVEN MENTIONED ANOTHER MODEL THAT HAD LIGHTS THAT WERE EVEN MORE EXPENSIVE.

OUR 2015 YUKON XL DENALI HAS BEEN IN FOR REPAIR SERVICE FOR 41 DAYS SINCE PURCHASED NEW 3/23/15. THE CAR HAS STALLED WHILE IN MOTION WITH MY WIFE AND THREE DAUGHTERS IN THE VEHICLE TWICE AND BEEN UNRESPONSIVE TO THROTTLE INPUT 3 ADDITIONAL TIMES. THE STALL OCCURRED ONCE WHILE TURNING LEFT ACROSS TRAFFIC AND ANOTHER TIME WHILE TURNING RIGHT AND MERGING WITH TRAFFIC! THE PROBLEM IS INTERMITTENT AND GMC HAS NEVER BEEN ABLE TO REPLICATE IT. THEY HAVE GIVEN US THE SHOULDER SHRUG, "I DON'T KNOW WHAT TO TELL YOU, WE CAN'T REPLICATE IT" LINE, SO HERE ARE YOUR KEYS. NO WARNING INDICATORS, NO SIGNS IT MAY HAPPEN, AND NO WAY TO PULL UP THE ISSUE WITH THEIR DIAGNOSTICS...HUGE SAFETY CONCERN AND EACH TIME THEY HAVE HANDED US THE KEYS BACK AFTER 7 DAYS (THEIR STANDARD ALLOTTED TIME TO HAVE A LOANER OUT) WITHOUT ANY PROACTIVE ESCALATION TO FIND ROOT...

MY NEW, 2015 GMC DENALI IS EQUIPPED WITH A BACKUP CAMERA AND THE QUALITY IS SO POOR AT NIGHT, AS TO MAKE IT NEARLY MORE DANGEROUS TO USE THAN TO IGNORE IT. I HAVE HAD 3 PRIOR GMC DENALI AUTOMOBILES. THE MOST RECENT WAS A 2011 WHICH WAS TRADED IN FOR THIS NEW ONE. THE QUALITY OF THE BACKUP CAMERA IN THE 2011 MODEL WAS EXCELLENT. MY WIFE AND I IMMEDIATELY NOTED ON THE NEW CAR THAT THE CAMERA IMAGE WAS SO BLURRY AND POOR RESOLUTION AT NIGHT, WE COULD NOT SAFELY USE THE CAMERA TO BACK OUT OF OUR GATED DRIVEWAY. IN THE DAYTIME, THE IMAGE IS BLURRY AS WELL, BUT USABLE. GMC HAS HAD THE CAR TWICE FOR SERVICE AND WE HAVE COMPLAINED TO GMC CORPORATE AND ALL WE GET IS A STATEMENT THAT THE "SYSTEM IS WORKING NORMALLY" WHICH IS DIFFICULT TO ACCEPT. THE NHTSA'S OWN STATISTICS...

TL* THE CONTACT OWNS A 2015 GMC YUKON. WHILE DRIVING 35 MPH, ALL THE WARNING LIGHTS ILLUMINATED AND THE FOUR WHEEL DRIVE LOW INDEPENDENTLY ACTIVATED. THE VEHICLE WAS TOWED TO A DEALER. THE TECHNICIAN DIAGNOSED THAT THE BODY CONTROL MODULE NEEDED TO BE REPAIRED. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE DEALER. THE TECHNICIAN DIAGNOSED THAT THE BODY CONTROL MODULE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 5,000. THE VIN WAS UNAVAILABLE.

I JUST COMPLETED A CLAIM FOR MY 2015 YUKON DENALI, NHTSA ID #: 10643049 AND READ THAT ALMOST THE SAME EXACT ISSUES ARE GOING ON WITH THE 2015 CHEVY TAHOE MODELS, SEE: NHTSA ID NUMBER: 10638437, 10633519 AND 10631583. WHEN WILL GM SEE THERE IS A PATTERN AND ISSUE A RECALL FOR THIS TRANSMISSION ISSUE? IN ALL CASES THESE RENDER THE CALLS UN-DRIVABLE AND HAVING TO HAVE THEM TOWED. *TR

I HAVE A BRAND NEW 2015 YUKON DENALI (SHORT WHEEL BASE) WITH LESS THAN A THOUSAND MILES AND A "SERVICE 4WD" MESSAGE THAT HAS APPEARED TWICE RENDERING THE CAR EXTREMELY UNSAFE AND UN-DRIVABLE FOR A LONG DISTANCE AND HAVING TO HAVE IT TOWED TO THE DEALER TWICE. A SOFTWARE UPDATE WAS DONE ON THE CAR THE FIRST TIME, ONLY RESOLVED THE ISSUE FOR A FEW WEEKS, THE ISSUE RE-OCCURRED AFTER 3 WEEKS. WHEN TURNING THE VEHICLE ON THE DASH GIVES THE MESSAGE "SERVICE 4WD". THE CAR HAS A TRANSMISSION BUTTON TO CHANGE FROM 2WD, AUTO, 4 HIGH AND 4 LOW. I DO NOT TOUCH THIS BUTTON, I JUST LEAVE THE CAR IN AUTO AND DRIVE. I DO NOT TOW ANYTHING, THIS IS JUST A FAMILY CAR USED FOR COMMUTING. WHEN THE "SERVICE 4WD' MESSAGE APPEARS, THE CAR IS BARELY DRIVABLE. WHEN IT IS PUT IN REVERSE, THE CAR JUST BRAKES...

DOOR LATCH IN THE LOCKED POSITION WHILE DOOR IS OPEN. CAR COMPUTER THOUGHT THE DOOR WAS CLOSED AND DOOR WAS OPEN. HAPPENED TWO TIMES IN ONE DAY. VERY SERIOUS PROBLEM IS DRIVER IS ALLOWED TO DRIVE WITH CHILDREN IN THE BACK SEAT WITH NO WARNING THAT THE DOOR DID NOT CLOSE. *TR
