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.
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!!!!!
SUV SHUTTERING AND SHAKING WHILE IN MOTION ON CITY STREETS AND HIGHWAY
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.
VEHICLE STARTED HAVING A VIBRATION AT CRUISING SPEEDS AFTER 100K MILES. DEALERSHIP STATES THE DRIVESHAFT IS WHARPED AND NEEDS REPLACING.. REAR TAILLIGHTS ALSO ARE GOING IN AND OUT INTERMITTENTLY. DEALER CLAIMS THE LEDS ARE BAD AND THE WHOLE LIGHT ASSEMBLY NEEDS REPLACING. I HAVE OWNED MANY VEHICLES AND HAVE NEVER HAD ISSUES WITH A BENT DRIVESHAFT OR DEFECTIVE TAILLIGHTS THAT REQUIRE THE WHOLE ASSEMBLY TO BE REPLACED. THE LIGHT ASSEMBLY IS $750 QUOTED BY DEALERSHIP.
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.
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.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
