2016 GMC YUKON XL Complaints

EXCESSIVE VIBRATION/BUFFETING DRONE ISSUES (AT ALL SPEEDS OF THE VEHICLE) HAVE CAUSED SEVERE HEALTH ISSUES AND SAFETY HAZARDS FROM DRIVING THE VEHICLE. WITHIN THE FIRST 8,000 MILES OF OWNING THE CAR, THE CAR HAS NOW BEEN IN SERVICE FOR 40 DAYS AS GM TRIES AND REMEDY THE PROBLEM, BUT THERE DOES NOT APPEAR TO BE A FIX. SO FAR, DIAGNOSTIC TESTS INDICATED THAT THERE WAS A FAULTY BEARING IN THE REAR DIFFERENTIAL THAT LED TO SIGNIFICANT ABNORMAL WEAR THROUGHOUT THE DIFFERENTIAL AND THE DIFFERENTIAL NEEDED TO BE REBUILT. WHEN REBUILDING, THEY DISCOVERED THAT THE DISASSEMBLED DIFFERENTIAL HAD HEAVILY SCORED BEARINGS AND METAL SHAVING THROUGHOUT EVERY BEARING. RING GEAR AND PINION HAD IRREGULAR WEAR CAUSING A DRONE IN THE VEHICLE. RACE SURFACES WEAR GROUND AND SCARRED BAD.THE REBUILT DIFFERENTIAL DID NOT FIX THE ISSUE AND NOW AFTER HAVING FOUR NEW TIRES AND ROAD BALANCING, THE PROBLEMS DIDN'T DIMINISH BUT WERE EXACERBATED. AFTER REBUILDING THE DIFFERENTIAL AGAIN, GM HAS NOW DETERMINED THAT THE REAR AXLE MAY NEED TO BE REPLACED AND ENGINEERS ARE LOOKING INTO THE PROBLEM FURTHER. THE STEERING WHEEL SHAKES AND THE CAR HAS A TERRIBLE VIBRATION THAT WORSENS EVERY TIME GM ATTEMPTS TO SERVICE THE VEHICLE. THIS SEEMS TO BE A WELL-DOCUMENTED PROBLEM THAT GM HAS AVOIDED FIXING. WE ADVISE OTHER CONSUMERS TO BE AWARE OF THE SERIOUS SAFETY PROBLEMS RELATED TO THE POOR MANUFACTURING OF THE VEHICLE AND INABILITY OF GM TO REMEDY THE PROBLEM.

IN MY YUKON WHILE IDLEL THE CAR START SHAKING SO BAD, IT HAS A VIBRATION YOU CAN SEE THE NEEDLE GOING UP AND DOWN, TOOK IT SEVERAL TIME TO THE DEALER AND THEY SAID THEY KNOW IS A PROBLEM WITH THE CAR BUT GENERAL MOTOR COMPANY HAS NOT ISSUE ANY REPAIR FOR THAT AT THIS MOMENT, I CONTACT GENERAL MOTOR COMPANY THEY SAID THE CAR IS OPERATING NORMAL BASE ON THE REPORT PROVIDED BY THE DEALERS, FOR ME IS NOT NORMAL HAVING A BRAND NEW CAR SHAKING AND VIBRATING LIKE IF WILL TURN OF, LOOKS LIKE IF MISFIRED ON THE ENGINE,

TL* THE CONTACT OWNS A 2016 GMC YUKON XL. WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE VIOLENTLY VIBRATED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO A DEALER WHERE THE TECHNICIAN REPLACED THE WHEELS, BUT THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE DEALER. THE CONTACT WAS INFORMED THAT THE VEHICLE WAS OPERATING AS DESIGNED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 2,000.

VIBRATION AT SPEEDS OVER 72 MPH BECOMES WORSE WHILE GOING UP GRADE WHILE ACCELERATING ..HAS BEEN IN SHOP MANY TIMES NEW TIRES, BALANCED MULTIPLE TIMES ,ALONG WITH SUSPENSION PARTS AND DRIVE TRAIN PARTS. STILL NOT FIXED SUV HAS 22 INCH RIMS.

I LEASED A 2016 YUKON DENALI XL ON 9/15/15. IT HAS TWO MAJOR PROBLEMS. 1. BUFFETING/PRESSURE NOISE - A NOISE AS IF A WINDOW IS CRACKED, EXCEPT IT'S NOT CRACKED. THIS OCCURS AT SPEEDS FROM 24MPH AND UP AND CAUSES EARS TO POP AND IS NOTICEABLE TO VIRTUALLY EVERY PASSENGER I HAVE HAD. 2. WHOLE-TRUCK VIBRATION - OCCURS BETWEEN 70-80MPH IN ENTIRE VEHICLE. WHEEL REPLACEMENTS, TIRE REPLACEMENTS, ROAD-FORCE BALANCING, DRIVESHAFT REPLACEMENT, DRIVESHAFT "BALANCING", ETC....NOTHING HAS FIXED IT. I HAVE DRIVEN 13 2016 YUKON, YUKON XL, TAHOE AND SUBURBANS. EVERY SINGLE ONE HAS THE BUFFETING ISSUES. ALL BUT ONE HAS THE VIBRATION ISSUES. GM HAS ISSUED A PI STATING THAT THE ROOF BOWS MAY HAVE COME DISCONNECTED AND THEY NEED TO BE REATTACHED. THE ISSUE HERE IS THAT REATTACHING THEM DOESN'T FIX THE BUFFETING ISSUE. I HAVE A DATE-STAMPED LOG OF EVERY DEALER VISIT, CONVERSATION, EMAIL, ETC. AND AM GLAD TO SHARE IT. THESE ISSUES ARE RIDICULOUS TO OCCUR IN ANY CAR MUCH LESS A 75K FLAGSHIP CAR THAT PULLS IN 3-7K IN PROFIT FOR GM/DEALERS PER VEHICLE.

ON 11/13/15, "SERVICE 4WD SYSTEM" MESSAGE APPEARED ON THE SCREEN RENDERING THE VEHICLE UNSAFE TO DRIVE. THIS ISSUE OCCURRED LESS THAN A WEEK AFTER PURCHASE (297 MILES ON THE ODOMETER AT THE TIME THAT THE ISSUE OCCURRED). SPECIFIC ISSUE: WHEN THE TRANSFER CASE WAS SET TO "AUTO" IT AUTOMATICALLY SWITCHED TO THE "4WDLO" SETTING, WHICH CAUSED THE VEHICLE TO LOCK-UP SPECIFICALLY WHEN TURNING OR IN REVERSE GEAR. I HAD THE VEHICLE TOWED TO DEALER AND WAS TOLD THAT THE TRANSFER CASE CONTROL MODULE SOFTWARE NEEDED TO BE UPDATED / REFLASHED AND THAT THE ENCODER MOTOR / ACTUATOR NEEDED TO BE REPLACED. THE DEALER CONTACTED GM AND WAS NOTIFIED THAT THE ENCODER MOTOR / ACTUATOR WAS ON NATIONAL BACKORDER. THE DEALER RECEIVED AND INSTALLED THE PART ON 12/8/15 (25 DAYS AFTER THE ISSUE OCCURRED). I FORMALLY SUBMITTED A COMPLAINT TO GM ON 11/20/15 (REF # 8-1674527570) SO THEY ARE AWARE OF THE ISSUE.
