I HEARD A REPETITIVE CLICKING SOUND AND TURNED MY RADIO OFF TO LISTEN. THE NOISE DIDN'T CHANGE WHEN I SLOWED DOWN AND I RESUMED MY NORMAL SPEED OF 60 MPH. AFTER A FEW SECONDS THE CAR SLOWLY & GRADUALLY BEGAN PULLING TO THE LEFT. I WAS UNABLE TO STEER THE VEHICLE AT ALL AND WAS MOVING INTO THE SHOULDER AND MEDIAN BETWEEN THE HIGHWAYS. I TRIED TO APPLY MY BRAKES BUT THE CAR WAS NOT RESPONDING. I HAD NO STEERING OR BRAKES AND WAS HEADING TOWARDS ONCOMING TRAFFIC AT 60 MPH. I HIT THE END OF A GUARD RAIL AND THE AIR BAGS DID NOT DEPLOY. THESE CARS ARE NOT SAFE TO DRIVE! WE ALSO HAD A PROBLEM W/IT HESITATING WHEN IT TRIED TO SWITCH GEARS & THE DEALERSHIP WAS UNABLE TO FIX. AND THE DRIVER WINDOW WOULD NOT STAY IN THE TRACK AND SHUT PROPERLY.*AK
