    New Member Introduction & Forum News/Guide
    I have a 2015 Mazda3 and today, for the first time, my security icon started flashing. It is the padlock intertwined with the car symbol, but I am not able to submit a picture in acceptable format for this forum. Why, all of a sudden, has this happened?
