2014 MAZDA CX-9 Steering Problems

HEARD LOUD GRINDING SOUND FROM RIGHT REAR SIDE OF VEHICLE WHEN TURNING WHEEL TO THE RIGHT. BROUGHT TO MECHANIC AND NEEDED R REAR WHEEL BEARING AND HUB ASSEMBLY COSTING $1000.00. NOTICED THERE HAVE BEEN OTHER COMPLAINTS ABOUT THIS ISSUE.

1) WHEN LEFT PARKED FOR 2-3 DAYS, MAZDA CX-9 (MINE IS 2013) CONSISTENTLY DRAINS THE BATTERY 2) ON MY GRAND TOURING THE STEERING HAS A SHAKE AT ABOVE 60 MPH THE ABOVE PROBLEMS ARE COMMON ON ALL MAZDA CX-9 AND CONSUMERS ARE SPENDING $$$ ON THESE MANUFACTURER ISSUES

I PURCHASED THE CAR WITH 7,000 MILES AND SINCE THE BEGINNING THERE HAS BEEN A HUMMING NOISE EVERY TIME I TURN THE STEERING WHEEL TO EITHER SIDE. I TOOK IT TO THE DEALER AND THEY TOLD ME IT WAS A PIECE OF PLASTIC STUCK TO THE CONTROL ARM. THE CAR CONTINUED MAKING THE NOISE ONLY AUDIBLE ON A QUIET NIGHT AND NOW THE CAR HAS 30,000 AND HUMMING IS MORE PRONOUNCED DAY AND NIGHT WITH ONLY SLIGHT TURN ANGLE. THE OTHER ISSUE IS THE DRIVERS SEAT HAS A LITTLE PLAY, FELT DURING TURNS. AND THE LAST ISSUE IS THE USB JUST STOPPED WORKING
