    2004-2009 Mazda3 Discussion
    Hi All Within one tank of fuel my mileage went from 29-30 to around 20/21mpg. I have tried everything I can think of to correct the problem without any effect. What I have done so far : 1) Replaced spark plugs - The old ones looked OK, no unusual build up. 2) New Filter 3) New MAP sensor...
  2. Sudden Security Icon Flash

    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?

  6. Sudden throttle drop-off
