  1. 2012 Mazda 3 hatchback, transmission mystery

    2010-2013 Mazda 3 Engine and Performance
    I have a 2012 Mazda 3 hatchback. Bought it used at 66k miles and now has 110k on it. I’ve driven and taken care of it the past 3 years and it’s worked GREAT. However in October it broke down. I was driving to work and the engine revved up and then wouldn’t go forward anymore. I pulled over and...
  2. Help identifying mystery part!

    2014-2018 Mazda 3 Skyactiv Discussion
    Hi folks, this is my first post here. I'm working on my wife's new-to-her 2016 3 GT 6MT hatch with the factory lower body kit. The front "splitter" had come separated from the bumper (surprise?) because it's largely held together with foam tape. I was also putting in Hella Supertones and LED...
  3. mystery foam inside intake manifold

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    My best guess is some sort of baffle for noise reduction as it is not attached to anything, just bumbling around in the void under the intake runners above the plenum. If you feel around, there are a couple more foam blocks that are attached somehow in that same space, anchored to something...
  4. Push To Start mystery!

    2014-2018 Mazda 3 Skyactiv Audio & Electronics
    Greetings, again! I said in my introduction thread, I'm probably gonna lay the questions on thick, and I'm itching to start with one that I've posted twice in the r/mazda3 subreddit.

  6. Mystery Part

    2004-2009 Mazda 3 Performance & Mods
    I recently had the transmission rebuilt on my 2004 Mazda 3 and my mechanic said that a mystery part fell from somewhere. Naturally, this has me concerned. He seems pretty sure that it didn't come from the transmission and I trust him that he has rebuilt more than a few of these. So I'm hoping...

    Interior / Exterior
    I recently found a plastic clip (pictures attached) lying on the driver-side floor of my 2016 Mazda 3. I have no idea where it belongs. I haven't noticed any new buzzing, rattling, etc. Can anyone tell me where this clip belongs?

  9. Cracked Paint Around Side Sill Plugs + Mystery Pegs In Rear Doors

    2014-2018 Mazda 3 Skyactiv Discussion
    Hi everyone, I just picked up a 2016 3, and have noticed that a few of the plastic plugs in the underside of the side sill/rocker panels have already started to show paint cracking around them (since Mazda install the plugs before they paint the car). I can only assume the cracking of the...

    2004-2009 Mazda3 Audio & Electronics
    I just did a radiator support frame swap on my 2009 mazda 3 5-door. I got it all buttoned up when I noticed that there's a 2-wire connector that I didn't reconnect, clipped just behind the top of the radiator support frame branching off the front wiring harness, to the driver's side of the...

  12. 2015 M3 i Touring, Mystery Fog Light Indication

    2014-2018 Mazda 3 Skyactiv Appearance & Interior
    I was getting to know the new vehicle and turned on the fog lights (true they only come on when the headlight is on and not with brights). Per page 4-25 and 4-50 of the 2015 Owner's Manual, I was expecting a fog light indicator to come on in the Dash. The Owner's manual states (pg 4-50): "The...

  14. Mystery Bolt... Help Please!

    2010-2013 Mazda 3 & Skyactiv Discussion
    I found this bolt under the front right side of my 2011 Mazda 3 2.5 hatchback in my garage today. It has the markings "307A CS" on it, and is about 1" long. I couldn't seem to find any matching bolts anywhere in the engine bay or under the car, and I'm still wondering if it's even from my car...
