MY WIFE WAS DRIVING THE VEHICLE ON A STATE ROAD. WHILE MAKING A LEFT TURN FROM THE LEFT LANE THE KEY BLADE SEPARATED FROM THE KEY FOB AND FELL TO THE FLOOR. THE KEY FOB HAS A ENGINE IMMOBILIZER AND WHEN IT FELL THE ENGINE SHUT OFF. WITH NO POWER STEERING OR BRAKES THE VEHICLE WOULD NOT TURN PROPERLY WHICH CAUSED IT TO GO STRAIGHT INTO ANOTHER VEHICLE IN THE RIGHT TURN LANE. I FEEL THIS IS A SAFETY DEFECT OF THE KEY DESIGN. THE KEY BLADE POPS OPEN FROM THE FOB AND GETS LOOSE AS TIME GOES BY. THE MANUFACTURER'S POSITION IS THIS IN NOT A DEFECT BUT NORMAL WEAR. A $50,000 VEHICLE LESS THAN SIX YEARS OLD SHOULD NOT HAVE THIS PROBLEM. ESPECIALLY WHEN IT CAN BREAK ANYTIME AND CAUSE A ACCIDENT LIKE MY WIFE HAD.
