THE TURN SIGNAL IS NOT AUDIBLE WHEN THE TOP IS DOWN. NISSAN COULD USE THE RADIO, HORN OR DOOR LOCK SOUNDER FOR THIS. THIS IS THE MOST POORLY DESIGNED CAR I HAVE EVER OWNED! THERE ARE SO MANY OTHER DESIGN FLAWS - RADIO, DEALER SERVICE, LIGHTS - I AM NOT GOING TO WASTE MY TIME LISTING THEM SEPERATELY. I WILL NEVER BUY ANOTHER NISSAN VEHICLE AFTER OWNING THIS VEHICLE, IN FACT, I AM GOING TO SELL IT AT A LOSS JUST TO GET RID OF IT.
