DT: THIS IS A CONVERTIBLE CAR AND THE BOLTS KEEP FALLING OUT OF THE TOP WHEN DRIVING ON THE HIGHWAY. THERE ARE TWO BOLTS THAT HAVE FALLEN OUT THREE OR FOUR TIMES. THE CONSUMER HAS CONTACTED THE DEALER AND AN APPOINTMENT WAS SET TO HAVE THE CAR LOOKED AT BECAUSE THERE IS A RATTLING SOUND COMING FROM THE CAR. THE CONSUMER THINKS THAT THE BOLTS ARE CAUSING THE NOISE. THIS PROBLEM STARTED IN JUNE 2005. *AK *MR
