Hey all! Proud new owner of a pretty sweet (IMO) 2015 hatchback here. I just bought the car a few days ago and haven't been able to smog it just yet due to it having a cold air intake on it that isn't CA legal. I have about 5 days left before the DMV will start charging me late fees and I have...

Hi everyone. I recently got a 2016 Mazda 3 S Touring HB. I previously had a 2011 rx8 that I loved, but due to rising gas prices, general maintenance, and having a baby, I traded for the newish car. My wife and I also have a 2016 cx5 that we really enjoy as well. I look forward to seeing what I...

If you turn the ignition on in a 2019 Mazda 3 but don't start the engine, should there be a buzzing noise in the engine bay? If so, what is it?

I am trying to install an additional horn for my 2016 Mazda3 and im trying to feed the wire from the battery to a button in the cabin. Where can I feed the wire the engine bay to the inside of my car?

I have a 2010 Mazda 3 with almost 280000 kms on it. Ever since I bought the car 3 years ago, something in the engine bay rattles whenever the car needs to shift down. If I don’t give the car any more gas it will stay that way and rattle until I give the car more gas and allow the car to shift...

I signed up for my first auto-x cross event at Sonoma raceway for July 7th. I'm throwing an invitation to anyone in the Bay Area that wants to come and drive in a non-competitive environment. SpeedSF is the track organizer and they are very relaxed with their auto-x policy. They do not even keep...

I would like to know how many of you wash you engine bay? A memory popped into my head of when I was at a local do-it-yourself car wash and some dude was washing his engine bay out with high-pressured water. On a BRAND NEW BMW! I mean, who does that to their obviously new car? For me, I do not...

Hello All! I joined because soon i hope to buy a trusty Mazda 3 hatchback and be a part of the club! I do have a very specific question about one that I test drove today, should I make a separate thread for it? The whole car seemed to pulse/vibrate at about 60-75mph, is it the PMM? Maybe the...

Installed some leds in the lower bumper openings of my 2013 M3 Sky. I used an auto relay that is currently using the low beams as the trigger to turn the LEDs on. However, I would like to have them on all the time when the ignition is on. If I could somehow hook up two triggers (one from...

My nephew just got a 2013 Mazda 3 I Touring fully loaded and it's his first car. Already has the mod bug and helping him research and install the parts. Great forum and look forward to learning and sharing lots.

Hi Guys, I would like to wash and clean my engine bay for the first time. I have purchased Meguiar's engine degreaser to agitate the dirt/grim and also the Ultimate Black to restore the inner plastic trim pieces to a new and clean look. So, before I do this I would like to know the following...

Rewiring LED DRLs and I need a location to put these so they are on when I start the vehicle. I've got the piggyback fuse wire and just need a spot that can safely fail if needed.

Hello everybody! My name is Chris, some call me Dill, and I recently acquired a Jet Black 2017 Mazda 3 Hatchback Grand Touring with the premium package and 6 speed manual transmission! I am loving it so far! I cross shopped just about everything in the class but the ergonomics, attention to...

Hi all, Being brand new to both these forums as well as Mazda in general, was hoping to find some local activity or meet ups, but not seeing anything in the Bay Area? Or am I just not looking hard enough?

Hey! I have an easy access to offers of 2,5l Skyactiv used, low mileage engine ( 192hp / 250 nm of torque here in Europe ) and I want it to swap it instead of my current 2,0l 165hp 210nm Skyactiv. My friend's colleague runs a fine tuning workshop and probably could perform the swap for my...

After using someone else's ratchet over the weekend, I got used to a very resistant release button. When I got back from the trip, I found my car would barely start. I picked up a new battery today at costco and when I went to put it in, my finger slipped and released the drive right into the...

Hi from the Northern California! I picked up my '16 Mazda 3 s GT hatchback in Liquid Silver last night. Super psyched to have a Mazda 3 as my first personally purchased car. I drove a '89 Mazda 626 when I was younger and still have it in the family! I'm hoping to take my car out to Pacifica or...

Adding a little washer fluid last night to my 2 month old car and found this in the engine bay right next to the belt assembly. I'm glad I found it. I keep thinking if it fell into the moving belt assembly and got shot into something like the radiator. All goes back to the dealer I bought...
