WHILE DRIVING ON A WINDY MOUNTAIN ROAD AT APPROX 45 MPH, GOING INTO A SHARP LEFT HAND TURN, THE STEERING WHEEL WOULD NOT TURN ANY FURTHER. IT FELT AS THOUGH THE STEERING HAD GONE OUT COMPLETELY. THIS CAUSED ME TO TRAVEL STRAIGHT INTO AN EMBANKMENT AND LAUNCH INTO THE WOODS. NO INJURIES. AIR BAGS DID NOT DEPLOY. RADIATOR WAS BENT INTO A U SHAPE. NO IDEA WHY NONE OF THE AIRBAGS DIDN'T DEPLOY
