I OWN 2010 QX56. ON NOVEMBER 16TH I WAS COMING OUT OF PARKING GARAGE AT CHICAGO O'HARE AIRPORT. AFTER I PASS THE PAY BOOTH, WITH IN 15 FEET AT THE SPEED OF 4 TO 5 MILES PER HOUR, I LOST CONTROL OF THE STEERING WHEEL BECAUSE OF SOME MALFUNCTION OF THE STEERING WHEEL ASSEMBLY. STEERING WHEEL MOVED 180 DEGREE IN ONE SECOND AND HIT THE PAY-BOOTH. CAR HIT THE SIDE PAVEMENTS OF THE PAY-BOOTH AND CAUSED THE FLAT TIRE, DAMAGE THE BODY OF THE CAR AND STEERING WHEEL GOT LOCKED. ALL THE POWER-STEERING FLUID GOT LEAKED OUT. I HAD A FRACTURED THUMB BECAUSE OF THE RAPID MOVEMENT OF THE STEERING WHEEL. CAR WAS NOT DRIVABLE AND ENDED UP TOWING TO THE DEALERSHIP. DEALER REPLACED THE WHOLE STEERING WHEEL ASSEMBLY. THIS CAN BE A MAJOR SAFETY ISSUE. I WAS JUST ABOUT TO GO ON A HIGHWAY. IF THIS WOULD HAVE HAPPENED ON THE EXPRESSWAY. I AM NOT SURE I WOULD BE ALIVE. *KB
