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

ANYTIME THE VEHICLE IS RUNNING THE FUMES FROM THE EXHAUST MAKE ME AND MY KIDS FEEL NAUSEOUS AND GIVING HEADACHES JUST FROM WALKING TO/AROUND THE TRUCK TO GET IN. WE ARE TAKING THIS TRUCK TO THE DEALER ON MONDAY. BEING THE 3RD DEALER WE HAVE TAKEN IT TO IN THE PAST YEAR. HAVE HAD MANY OTHER ISSUES OUT OF THIS VEHICLE AND JUST CANT SEEM TO GET THEM ALL FIXED. FOR SUCH A PRICEY VEHICLE YOU WOULDNT THINK THERE WOULD BE THIS MANY PROBLEMS. THE LIFT GATE IS POPPING NOT WANTING TO OPEN OR SHUTS ON YOU AS YOU WALK UNDER IT. THE WINDOW APPLIQUES ARE JUST SLOWLY FLYING OFF 1 BY 1. TRANSMISSION IS HARD SHIFTING IN LOW GEARS, DURING ACCELERATION AND DECELERATION. WE HAVE A HORRIBLE GRINDING/SQUEAKING NOISE IN THE FRONT THAT YOU CAN FEEL IN THE FLOOR BOARDS. THE BRAKES, WE HAD A MODULE REPLACED, BUT IT STILL FEELS AS IF WHEN PUSHING THE PEDAL IT LOOSES PRESSURE, CAUSING NEAR ACCIDENTS. THIS IS INSANE!!!!!! BOOUGHT THIS TRUCK JUST OVER A YEAR AGO AND HAVE HAD NOTHING BUT PROBLEMS. WASTE OF TIME AND MONEY!

VEHICLE SPUTTERS WHEN DRIVING OFF FROM A START OR ACCELERATING WHILE DRIVING ALSO WHEN COMING TO A COMPLETE STOP, AFTER BEING STOP IT FEELS LIKE THE TORQUE CONVERTER IS NOT IN SYNC WITH THE REST OF THE TRANSMISSION MAKING IT FEEL LIKE SOMEONE HIT YOU FROM BEHIND TOOK IT TO MY LOCAL DEALER THEY PERFORMED A TRANSMISSION FLUSH AND A REFLASH OF THE COMPUTER IT SEEMED TO FIX THE PROBLEM BUT CAME BACK AFTER ABOUT A MONTH OR SO, DEALER STATED THAT ANOTHER RECALL WAS COMING IN MARCH OF 2019 (STILL WAITING) THAT WAS GOING TO SOLVE THE PROBLEM. GM NEEDS TO ADDRESS THIS PROBLEM WITH THE POWERT TRAIN BELIEVE THE AFFECTED YEARS FOR GMC YUKON IS 2015, 2016, 2017 THERE IS A CLASS ACTION LAWSUIT OUT THERE ABOUT THIS. GOOD LUCK EVERYONE

WHILE TRAVELING DOWN HILL ON LONG GRADES THE TRANSMISSION DROPS TO NEUTRAL OR VERY LOW GEAR AND ENGINE REVS DROP TO IDLE. THE GRADE BREAK DISENGAGES AND THE VEHICLE FREE WHEELS AND HENCE SPEEDS UP. THE ONLY WAY TO RE-ENGAGE THE TRANSMISSION IS TO EXCESSIVELY REV THE ENGINE. THIS IS HAS BEEN AN INTERMITTENT ISSUE OVER THE LAST 18 MONTHS AND I HAVE NOT BEEN ABLE TO REPLICATE AT A SERVICE CENTER.

BRAKES DON'T WORK WELL WHEN TRAVELING AT LOW RATES OF SPEED. STOPPING REQUIRES BRAKES TO BE PRESSED TO THE GROUND AND STILL MAY NOT STOP. I HAVE ALMOST HAD SEVERAL ACCIDENTS EVEN AFTER HAVING THE ISSUE 'REPAIRED' LAST YEAR. I'VE HAD THE PROBLEM ASSESSED AT 3 DIFFERENT MECHANICS. I HAVE HAD TO THROW MY CAR INTO PARK TO AVOID HITTING CARS IN FRONT OF ME. BRAKES FAIL WHILE DRIVING IN PLACES SUCH AS TRAFFIC JAMS, DRIVE THRU, SCHOOL PICK UP, ETC. THIS IS A HUGE SAFETY HAZARD AND FEAR THAT MY CHILDREN MAY BE HURT IF THIS ISSUE IS NOT CORRECTED BY THE MANUFACTURER. STEERING BECOMES NEARLY IMPOSSIBLE WHEN THE BRAKE ISSUES OCCUR. THIS IS AN ONGOING PROBLEM FOR THE LAST 1.5- 2 YEARS. ALSO, THE TAIL LIGHTS CONTINUE TO GO OUT EVEN AFTER PAYING HUNDREDS OF DOLLARS FOR REPLACEMENTS.

MY YUKON MAKES VERY HARD SHIFTS WHEN ACCELERATING AND DECELERATING. THE TCM WAS REPROGRAMMED AFTER VEHICLE SHUT OFF ON THE HIGH WAY LAST NOVEMBER. NOW THE TRUCK SHUDDERS BETWEEN 25 AND 45MPH ESPECIALLY WHEN CLIMBING OR FILLED WITH PASSENGERS. VIBRATION CAN BE FELT THROUGH THE CABIN.

TL* THE CONTACT OWNS A 2015 GMC YUKON DENALI XL. WHILE ATTEMPTING TO SHIFT THE VEHICLE FROM PARK INTO DRIVE, THE TRANSMISSION MADE A HARD CLUNKING SOUND. ALSO, WHILE DRIVING BETWEEN 30-50 MPH, THE VEHICLE VIBRATED ABNORMALLY. THE VEHICLE WAS TAKEN TO LEWIS CHEVROLET BUICK OF LIBERAL (LOCATED AT 202 N GRANT AVE, LIBERAL, KS 67901, (620) 624-2584) WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION FLUID NEEDED TO BE FLUSHED AND REFILLED. THE VEHICLE WAS SERVICED, BUT THE FAILURE PERSISTED. THE MANUFACTURER WAS CONTACTED. THE FAILURE MILEAGE WAS UNKNOWN.

THE VEHICLE WILL OFTEN SHIFT UNPREDICTABLY. MOVING FROM A DEAD-STOP, THE VEHICLE WILL SOMETIMES DEMONSTRATE SIGNIFICANT HESITATION (TO SHIFT) FOLLOWED BY A LOUD AND VIOLENT ENGAGEMENT. IN SOME INSTANCES THE VEHICLE FEELS LIKE IT HAS BEEN HIT BY ANOTHER VEHICLE. THE AUTOMOBILE WILL SHUDDER AND SLIP AND JERK WHEN IT SHIFTS BETWEEN GEARS. THE VEHICLE IS UNSAFE TO OPERATE. THE DEALER CAN NOT FIX THE ISSUE, BUT UNDERSTANDS THE VEHICLE PROBLEMS.

AT 75,000 MILES I WOULDN'T EXPECT TO HAVE THIS MANY ISSUES OUT OF SUCH A NICE EXPENSIVE TRUCK... THE CHECK ENGINE LIGHTS COMES ON AND OFF AND IT PLEASES. WHEN THE CHECK ENGINE LIGHT IS ON THE REMOTE START DOESN'T WORK. THE TAIL LIGHTS WORK WHEN THEY WANT TO AND TO FIX A TAIL LIGHT JUST 1 IS $800.00. WHILE DRIVING ALL TYPES OF WARNINGS AND LIGHTS START COMING ON IN A RAPID WARNING ANNOYANCE. I'VE NEVER HOOKED A TRAILER TO THIS TRUCK AND IT KEEPS GIVING ME SOME TYPE OF TRAILER BRAKING SYSTEM WARNING. THE CRUISE CONTROL WORKS WHEN IT WANTS TO. BIG ISSUE!!!!! THE TRANSMISSION IS SLIPPING!!!!!!!!!!!! WHEN DRIVING IT WILL GIVE A HARD JERK AS IF IT'S HAVING TROUBLE SHIFTING. DOING THIS AT ANY SPEEDS, ANYTIME DURING ACCELERATING. SO MANY ISSUES OUT OF THIS TRUCK IT'S TO THE POINT WE ARE THROWING AWAY A TON OF MONEY ONTHIS THING!!!!!

NHTSA ODI 11204356

ON REPEATED OCCASIONS (FROM 2015 TO 2019) I HAVE EXPERIENCED SUDDEN ACCELERATION AT LOW SPEEDS AND SUDDEN JERKING MOTIONS. THE TRANSMISSION AND SPEED CONTROLS ARE UNPREDICTABLE AND DANGEROUS. THIS IS HAZARDOUS AND MAY RESULT IN A LOSS OF CONTROL. I HAVE ALSO EXPERIENCED NUMEROUS ISSUES WITH THE BRAKES INCLUDING A STUCK CALIPER AT APPROXIMATELY 42,000 MILES. I REPORTED THESE ISSUES AND NUMEROUS OTHER ISSUES TO GMC CORPORATE, TUSTIN BUICK GMC ONLY TO BE TOLD THAT IT WAS A SOFTWARE ISSUE AND THINGS ARE SATISFACTORY AND SAFE. GMC CONTENDS THAT THE VEHICLE IS FINE AND DECLINES TO ASSIST WITH ISSUES. THIS IS AN ONGOING ISSUE. THE DATE BELOW IS APPROXIMATE. THE MILEAGE IS APPROXIMATE ON ALL ENTRIES.

THE 8 SPEED AUTOMATIC TRANSMISSION ON MY GMC YUKON DENALI HAS A SLIPPAGE ISSUE THAT HAS PERSISTED IN OUR VEHICLE FOR A WHILE UNRESOLVED. GM HAS REPLACED TORQUE CONVERTER, MODULE AND NOW THEY ARE CLAIMING THROUGH DEALER THAT THE ISSUE RESIDES WITH AT FLUID. THIS SLIPPAGE IS BAD BECAUSE CAR JERKS AND SOMETIMES HARD. THIS ISSUE NEEDS TO BE ADDRESSED BY GM AS THEY KNOW THEY HAVE ISSUES WITH THIS 8 SPEED AT. THE ISSUE HAPPENS AT STOPS AND AT SLOW SPEEDS.

SUV SHUTTERING AND SHAKING WHILE IN MOTION ON CITY STREETS AND HIGHWAY

NHTSA ODI 11191809

I WAS DRIVING UP NORTH IN 4WHEEL DRIVE AND TRANSMISSION CAM OUT OF GEAR I STOPPED THE VECHILE AND RESTARTED NOW THE TRANSMISSION DOES NOT SHIFT PROPERLY AND STEERING IS HARD TO STEER AND IT GOES IN AND OUT

NHTSA ODI 11190131

WHEN COMING TO A STOP THERE WOULD BE A SUDDEN SURGE AND IT FELT LIKE THE VEHILCE WAS BEING PUSHED FORWARD. THERE HAS BEEN A FEW OCCASIONS WHERE WE ALMOST HIT SOMETHING IN FRONT OF US BECAUSE OF THIS SURGE. THERE WAS A BAD SHUTTER THOUGH OUT THE VEHICLE AT 30 TO 50 MPH. MADE COMPLAINTS TO DEALER. THEY COULDN'T DUPLICATE THE PROBLEM. THIS WAS AT ROUGHLY 6K MILES AT THE TIME OF THE FIRST OIL CHANGE. AT 10K MILES THE VEHICLE STALLED OUT AND DIED IN OUR DRIVE WAY AFTER PUTTING IT INTO REVERSE TO BACK OUT. THE VEHICLE ROLLED BACK INTO THE STREET AS OUR DRIVEWAY IS AT A INCLINE WITH OUT ANY FUNCTIONS OR CONTROLS. LUCKY TRAFFIC WAS LIGHT AND THEY WERE ABLE TO AVOID HITTING US. I WAS ABLE TO START IT EVENTUALLY AND DROVE ITS STRAIT TO THE DEALERSHIP. THEY FOUND THE TORQUE CONVERTER WENT BAD AND REPLACED IT. COMPLAINED ABOUT THE ROUGH RIDE, NOISES AND LOOSE FEEL COMING FROM THE FRONT END SEVERAL TIMES AT 20,000 MILES AND 30,000 MILES. WHEN DRIVING THE VEHICLE OVER BUMPS WHILE IN A CURVE THE VEHICLE WOULD JERK TO THE SIDE PULLING THE STEERING WHEEL HARD TO THE SIDE IT WAS PULLED TOWARDS. THERE WERE A FEW OCCASIONS WHERE WE ALMOST HIT A VEHICLE OR CONCRETE WALL. THEY FINALLY REPLACE SOME COMPONENTS ON THE FRONT END. NO MORE NOISES FROM THE FRONT END FOR ABOUT 2,000 MILES AND THEN IT COMES BACK. THE SHUTTER IS BACK ALONG WITH ERRATIC SHIFTING. SERVICE REPLACES THE TORQUE CONVERTER AGAIN AT 45,000 MILES. THIS TIME IT LAST A LITTLE BIT LONG AND I DON'T START HAVING ISSUE WITH THE TORQUE CONVERTER UNTIL NEARLY 60,000 MILES. THE FRONT END STILL POPS, CREAKED AND FEELS LOOSE AT TIMES AND THE TORQUE CONVERTOR IS STILL FAILING.

A YEAR AGO, I WAS AT SERVICE AT THE SAME DEALER WITH A TRANSMISSION PROBLEM(TORQUE CONVERTER) WITH MY GMC YUKON XL 2015. WARRANTY TRANSMISSION WAS MADE 08/2017. ON 10/18/18, IN THE CITY OF ATLANTA GA ON HIGHWAY 400, THE CAR BEGAN TO TWITCH WHEN YOU PRESS THE GAS AND VIBRATE STRONGLY, UTTERING SOUNDS OF HOWLING, DRIVING WAS NOT SAFETY!!! RE-ISSUE REPAIR FROM DILLER CARL BLACK BUICK GMC ROSWELL GA.

I GIVE!!! NOW BREAK LIGHTS NOT WORKING!!! RIGHT BREAK LIGHT IS OUT AND LEFT DRIVER IS INTERMITTENT. VEHICLE HAS 37K ON IT AND WAS JUST PICKED UP FROM THE DEALER AFTER HAVING 1 OF MANY ISSUES THROUGH THE PAST YEAR RECTIFIED AND NOW THIS! THIS IS A SIGNIFICANT SAFETY HAZARD AND COULD TREMENDOUSLY INJURE SOMEONE. RIGHT NOW MY CAR CANNOT EVEN PASS INSPECTION DUE TO THE FAULTY EQUIPMENT INSTALLED BY THE MANUFACTURE THAT IS A DANGER TO MY SAFETY. I HAVE OWNED MANY GMC'S (6 TOTAL) THROUGH THE YEARS AND THIS BEING THE WORST!! THE LATEST, I HAVE HAD THE TORQUE CONVERTER REPLACED IN AUG 18 - DUE TO SHUDDERING AND VIBRATION. THEN THE STEERING COLUMN REPLACED DUE TO POPPING , BACK HATCH HINGE REPLACED DUE TO POPPING AND MALFUNCTION, BACK GLASS DOOR RUBBER GASKET REPLACED DUE TO LEAKING, SHARKFIN ANTENNA REPLACED DUE TO LEAKING, SUNROOF GASKET REPLACED DUE TO LEAKING, NEW TIRES AT 500 MILES DUE TO EXCESSIVE VIBRATION. BACK DOOR ADJUSTED DUE TO SLAMMING, AND ADDITIONAL SLIGHT ISSUES. THE RADIO HAS A CONSTANT GLITCH ON THE SCREEN SINCE DAY ONE THAT AFTER BEING TAKEN IN NUMEROUS TIMES, OF COURSE THE DEALER CANNOT REPLICATE THE PROBLEM AND KEEPS PERFORMING A FLASH UPDATE WHICH NEVER HELPS AND AS SOON AS I DRIVE OFF IT GLITCHES AGAIN. I HAVE CONTACTED GM REGARDING THE BRAKE LIGHTS, RADIO, AND NOW MY PASSENGER STEP IS MALFUNCTIONING NOT TO MENTION A RECALL WAS JUST RELEASED ON THE POWER STEERING. WILL THE REPAIRS EVER END? GUESS ONCE I TRADE IT IN ON ANOTHER MANUFACTURE AS THIS WILL MOST LIKELY BE THE LAST GMC I WILL EVER PURCHASE!! I DO NOT HAVE TIME TO LIVE MY LIFE AT THE DEALER FOR A HIGH END PURCHASE THAT IS THE WORST MISTAKE EVER!! NOT TO MENTION BEING A SAFETY HAZARD!!!

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.

I WAS RECENTLY IN AN ACCIDENT AT A STOPLIGHT. WHEN I ARRIVED AT THE STOPLIGHT SOMETHING FELL OUT OF PASSENGER SEAT ONTO FLOOR. I PUT THE TRUCK IN PARK, TOOK OFF MY SEATBELT, LEANED OVER TO PICK UP ITEM AND PUT IT BACK ON THE SEAT. I THEN PUT SEATBELT BACK ON AND PUT FOOT ON BRAKE AND PUT THE TRUCK INTO DRIVE. IT ALL HAPPENED PRETTY QUICKLY AND CAN'T SWEAR TO THE SPECIFICS BUT I THINK THE TRUCK MAY HAVE "JUMPED" A LITTLE WHEN I PUT THE TRUCK INTO DRIVE AND PROPELLED ME INTO THE CAR IN FRONT OF ME AT A VERY LOW SPEED. THE REASON WHY I BELIEVE THIS HAPPENED IS THAT I HAD PREVIOUSLY ASKED THE LOCAL GMC DEALER SERVICE CENTER IF THERE WERE ANY RECALLS OR OTHER REPORTS ON THIS TYPE OF THING HAPPENING BECAUSE IT HAPPENS WITH MY TRUCK. I HAD BEEN EXPERIENCING THIS "ENGINE JUMPING" UPON PUTTING IT INTO DRIVE ISSUE FOR SEVERAL MONTHS.
