WHILE DRIVING E. ON HIGHWAY 60 IN AZ, I NOTICED MY STEERING WHEEL STICKING ONCE IN A WHILE. AFTER DRIVING THRU DEVEL'S CANYON THE STEERING KEPT PULLING TO THE RIGHT A LITTLE THEN IT WOULD STOP PULLING, OVER AND OVER. WHEN I WAS ON FLAT ROAD AGAIN THE STEERING PULLED REAL SHARP TO THE RIGHT AND WOULD NOT TURN LEFT, AFTER A SECOND OF THIS THE STEERING FINALLY FREED ITSELF AGAIN BUT MAKING THE STEERING VERY TOUCHY, WHEN THIS HAPPENED THE CAR STARTED SWEERVING SIDE TO SIDE AND ENDED UP HITTING THE GUARD RAIL ON THE EAST BOUND SIDE OF THE HIGHWAY. I WAS GOING APROX. 52 MPH IN A 55 MPH AREA. WHEN I HIT THE GUARD RAIL THE CAR HIT ALMOST HEAD ON AND THE AIR BAGS NEVER WENT OFF.
