I NOTICED A LOUD INTERIOR NOISE THE FIRST TIME I DROVE THE CAR ON THE EXPRESSWAY. IT SOUNDS LIKE ROAD NOISE COMING FROM THE FLOOR BOARDS. I TOOK IT BACK TO THE DEALER ON TWO OCCASIONS BUT THEY CLAIM NOT TO HEAR THE NOISE EVEN THOUGH THEY COULD NOT HEAR THE RADIO AFTER GETTING ON THE HIGHWAY. THAT IS STRANGE BECAUSE WHENEVER I TALK ON MY CELL PHONE I CAN HARDLY HEAR THE CALLER BUT THEY CAN HEAR THE NOISE.
