2016 GMC YUKON Electronic Stability Control Esc Problems

VEHICLE SHUTS OFF AND ON WHEN MAKING A SHARP TURN. WHEN REVERSING INTO A PARKING SPOT THE TRUCKS STEERING WHEEL GOT STIFF AND EVERYTHING SHUT OFF OFF THEN ON THEN OFF AND ON AGAIN. WHEN REVERSING IT DID IT TWICE MORE. TURNING TO GET OUT OF A CAR WASH CURVE IT SHUT OFF AND ON. TURNING INTO MY DRIVEWAY IT SHUT OFF AND ON (ON TWO DIFFERENT OCCASIONS)

MY 2016 YUKON DENALI HAS A VIBRATION PROBLEM, WHICH I BELIEVE IS CAUSED BY THE MAGNETIC RIDE CONTROL. THE VIBRATION DOES NOT SPEED UP, NOR SLOW DOWN, DEPENDING ON SPEED. IT IS, HOWEVER, MORE NOTICEABLE WHEN THERE IS ANY ROAD IMPERFECTION. THE GMC SERVICE DEPT. HAS BALANCED AND ROTATED TIRES, EVEN SENT IT TO TWO OTHER BUSINESSES TO TRY AND FIX -- ALIGNMENT, ETC. VIBRATION CONTINUES. I'VE HAD PASSENGERS WHO ASK "WHY DOES YOUR CAR HAVE THE SHIVERS?" GM DEALER DID GET AHOLD OF A GMC TECHNICIAN WHO FLEW IN, AND DROVE THE CAR AND SAID -- YES IT HAS A VIBRATION, BUT IT IS IN ACCEPTABLE PARAMETERS. MY DEALER HAS PROVIDED ME 3 DIFFERENT RENTAL CARS WHILE WORKING TO TRY AND FIX THE "SHIVERS" ... ALL THREE WERE FAIRLY NEW, SMALL BUICKS, AND ALL 3 RODE BETTER THAN THIS NEW $75,000 DENALI. I LOVE THE VEHICLE, HATE THE VIBRATION....

WHEN THE VEHICLE REACHES 40-60 MILES PER HOUR A VIBRATION OCCURS... OFTEN SOUNDS LIKE A WINDOW IS DOWN AND CAN CAUSE NAUSEA AND HEADACHE...
