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

DRIVER SIDE BRAKE LIGHTS (ENTIRE LIGHT ASSEMBLY) NO LONGER WORK.

NHTSA ODI 11084062

REAR LED (BREAK LIGHT) DOES NOT WORK TURN SIGNAL, BACKUP WORKS. COST IS OVER $500 TO REPLACE THIS IS OUTRAGEOUS EXTENDED WARRANTY DOES NOT COVER LIGHT BULBS NOW I KNOW WHY THIS SHOULD BE A FACTORY DEFECT.

NHTSA ODI 11084220

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.

REAR TAILLIGHT & BRAKE LIGHT - INTERMITTENT OPERATION OF REAR LED MARKER AND BRAKE LIGHT ON DRIVER SIDE. VEHICLE HAS < 30,000 MILES. GM SELLING DEALER AWARE OF ISSUE WITH NO ACTION TAKEN.

NHTSA ODI 11082115

THE BRAKE LIGHTS ON MY 2015 ARE DEFECTIVE. THE DRIVER SIDE LIGHT WENT OUT ABOUT NINE MONTHS AGO AND NOW THE PASSENGER SIDE LIGHT IS OUT. OUR LOCAL DEALERSHIP WANTS $800 APIECE FOR THESE LED LIGHTS THAT SHOULD LAST MANY, MANY YEARS. A QUICK INTERNET SEARCH REVEALS THAT 1) THE PROBLEM IS WIDESPREAD AND 2) GM WON'T ACKNOWLEDGE IT. WORKING BRAKE LIGHTS ARE A MATTER OF SAFETY, AND THE FACT THAT GM PRODUCES THESE LIGHTS AS CHEAPLY AS POSSIBLE AND THEN CHARGES AN ARM AND A LEG AFTER THE PARTS FAIL EARLY IN THEIR LIFETIME IS SUSPECT TO SAY THE LEAST.

WIRING ON THE BRAKE LIGHTS IS FAULTY CAUSING THE LIGHT TO WORK ON AND OFF. WHILE DRIVING YOU DON'T KNOW IF YOUR BRAKE LIGHTS ARE WORKING BECAUSE THEY COME ON AND OFF AT TIMES

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.

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.

NHTSA ODI 11055927

I HAVE SPENT OVER $2000 ON A LESS THAN 2 YEAR OLD VEHICLE BECAUSE THE SHOCKS/STRUTS DID NOT HOLD UP. I KNOW OF 4 OTHER PEOPLE WITHIN MY SMALL COMMUNITY WHO HAVE HAD THIS SAME PROBLEM ON EITHER GMC YUKON OR CHEVY TAHOE. IT FEEL CERTAIN THIS IS NO COINCIDENCE.

THE PASSENGER SIDE HEADLIGHT ASSEMBLY WAS WORKING AND NOW AFTER HAVING THE TRUCK SINCE APRIL THE RUNNING LIGHT HAS GONE OUT COMPLETELY. IT WAS ALREADY HARD SEEING THE ROAD AHEAD WITH THE LIGHTS WORKING BECAUSE ALL OF THEM ARE SO DIM BUT NOW IT IS EVEN WORSE. THE ENTIRE HEADLIGHT HAS TO BE REPLACED BECAUSE OF MOISTURE INSIDE THE SO CALLED SEALED ASSEMBLY. I TOOK THE TRUCK TO THE DEALERSHIP ONLY TO FIND OUT THAT IT WILL COST ME $1200 PLUS DOLLARS FOR THE LIGHT AND LABOR THIS IS REALLY RIDICULOUS. I HAVE READ ON MANY DIFFERENT GMC FORUMS THAT THIS IS AN ALL AROUND STATE TO STATE PROBLEM THAT I THINK GMC SHOULD ADDRESS NOT ONLY BECAUSE OF THE COST BUT BECAUSE OF THE SAFETY ISSUES THAT THIS POSES. PLEASE DO SOMETHING ABOUT THIS PROBLEM.

NHTSA ODI 11048013

FUEL SMELL INSIDE AND OUTSIDE OF VEHICLE WHILE DRIVING AND PARKED. EXTENDED CRANK AFTER (OVERNIGHT) ENGINE OFF PARK. FUEL PUDDLE NOTICED UNDER PARKED VEHICLE ON GARAGE FLOOR AND DRIVEWAY AFTER OVERNIGHT PARKING. SMELL AND FUEL LEAK SEEMED WORSE WITH A FULL TANK. ALSO NOTICED MORE FREQUENT AUTO SHUT OFF AT FUEL STATION DURING AUTOMATIC FILLING. DEALER DROPPED TANK AND FOUND A FUEL LINE THAT WAS 'RUBBED' THROUGH TO THE POINT OF FAILURE. I WILL DOCUMENT WITH PICTURES UPON MY RETURN TO THE DEALERSHIP IF NEEDED FOR FUTURE. I FIND THIS COMPLETELY UNACCEPTABLE THAT ON A ($70K) 3 YEAR OLD VEHICLE THERE IS A FUEL LEAK THAT COULD HAVE BEEN PREVENTED WITH A 10 CENT PIECE OF INSULATION TO PROTECT THE LINES FROM RUBBING. SOUNDS LIKE SOMEONE CHOOSE TO LOOK THE OTHER WAY DURING VALIDATION TESTING! TOTAL BS.

PURCHASE A USED 2015 YUKON DENALI 1 YEAR AGO AND HAVE HAD ISSUES WITH BOTH SHOCKS AND AC. THE SHOCKS ARE THE AIR RIDE AND ALL 4 HAD TO BE REPLACED. THIS WAS A HUGE EXPENSE BECAUSE MY TRUCK SURPASSED THE MILEAGE EVEN THOUGH IT WAS WITHIN THE DATE RANGE. MY AC ALSO RESENTLY STOPPED WORKING. I RECEIVED A LETTER FROM GM 1DAY AFTER AC WENT OUT NOTIFYING ME ABOUT A KNOW ISSUE WITH A LEAKING COMPRESSOR. I TOOK IT TO THE DEALERSHIP THE NEXT DAY AND THOUGHT IT WOULD BE COVERED TO REPLACE. I THEN FOUND OUT THAT SINCE IT WAS OVER MILEAGE IT WASN'T UNDER WARRANTY. I QUESTIONED WHAT MILEAGE AD TO DO WITH A KNOW DEFECTIVE COMPRESSOR BUT WAS TOLD THEY COULD NOT DO ANYTHING. THE COST TO REPLACE IT WAS QUOTED AT $1,200.

STEERING WHEEL POPS WHEN TURNING STEERING WHEEL. 100'S OF COMPLAINTS ON THIS ISSUE. GMC ISSUES TSB TO ADDRESS THIS ISSUE BUT THEY WILL NOT COVER THE COST FOR THE REPAIR. IT'S A DEFECT IN THE STEERING COLUMN AND A SAFETY ISSUE THAT NEEDS TO BE REPAIRED FOR FREE

NHTSA ODI 11042217

MY VEHICLE HAS A SIGNIFICANT VIBRATION WHEN TRAVELING 40MPH AND ABOVE WITH A REAR WINDOW DOWN. THE VIBRATION IS ALSO ACCOMPANIED BY INCREASED CABIN PRESSURE. THESE ISSUES ARE CAUSING HEADACHES, NAUSEA, AND DIZZINESS. DEALERSHIP CONFIRMS ISSUE AND TRIED TO REPAIR, BUT UNABLE TO. THE VIBRATION STARTED RIGHT AFTER WE TOOK DELIVERY OF THE CAR AND HAS ONLY GOTTEN WORSE. WE BOUGHT THE CAR IN OCTOBER 2015 AND THE ISSUE CONTINUES UNFIXED TO THIS DAY AFTER 5 VISITS.
