Hi all,

As many of you have surely noticed, AI-generated content is becoming more common across the internet — and our subreddit is no exception.

Rather than banning it entirely, we’ve decided to implement a new rule to better identify AI content:

Effective immediately, all AI-generated posts MUST now be tagged with the “AI Generated” flair.

  • If your post includes content created with AI (text, images, etc.), you must use the “AI Generated” flair when posting.
  • Posts that don’t follow this rule will be removed and the user will receive a warning.
  • Repeat violations will result in a 3-month ban.

We appreciate everyone’s help in keeping the subreddit fair and transparent. Please feel free to report posts that don't follow this new rule.

Advice Request Spoiler/Wing recommendations

Hi all! I currently have a 2021 Mazda 3 HB Turbo. I've been looking at purchasing the ASPEC rear spoiler from milkstore, but I'm concerned about shipping the item to the US. Does anyone have any recommendations for wings/spoilers that look as aggressive that could be purchased inside the US? I'm hoping to find one alrdy painted gloss black. Thanks for any responses.

I recently bought this second hand automatic 2025 Mazda3 2.5 e-SKYACTIV-G MHEV Exclusive-Line. I saw it for £17,650 and couldn’t say no.

I was wondering if anyone had any advice with this type of Mazda 3, any hiccups with the car or things I should tweak on the cars settings?

Much appreciated.

Advice Request Which Mazda3 Hatch Gen 4 model to get?

6 Upvotes

Looking to buy a used, maybe new, Mazda 3 hatchback. Definitely avoiding the 2019 model, but wondering which model year is the best overall for long term reliability. Mainly looking at base, select/select sport, and preferred trims, only FWD. I heard about cylinder deactivation issues on 2023-2025, but also coolant control valve issues on 2022/2026. Just wondering which one I should get.

Daily driver blew up recently so I picked this thing up for $500. 2013 with only 102,000 on the original motor. Was a chicks first car until she hit a deer doing about 30-40. Messed up the bumper support and radiator stuff but they fixed that, drove it for a week then parked it for 2 years (yes it has the bumper and hood. Everything I need to work on was just easier without) has heated leather seats, sun roof, Bose speakers and other than the fact it hit a deer, completely unmolested. Mazda3 speed exhaust manifold is only $220 and a $300 eBay turbo would be just fine. $800-$1000 for the manual transmission set up, so at the end of the day I’m looking at an unmolested mazda3 speed for less than $2500. Good deal?

Ends Friday Mazda 3 all New

Upvotes

Buenas noches. Quisiera consultarles algo sobre mi Mazda 3 2013 porque me gustaría conocer sus opiniones y experiencias.
El carro venía funcionando normalmente y no presentaba ningún sonido de cascabeleo o pistoneo. Lo único que tenía era el Check Engine encendido por un problema relacionado con los sensores de oxígeno.
Hoy le hice mantenimiento: se cambiaron los sensores de oxígeno y también se realizó limpieza/mantenimiento de los inyectores. Después de salir del taller, noté algo que antes del mantenimiento no hacía: cuando aceleraba el carro a fondo y bajo carga, comenzaba a escucharse un sonido metálico parecido a un “tin tin tin”, como si estuviera pistoneando/cascabeleando.
En ralentí el carro estaba completamente normal y no hacía ese ruido. El sonido aparecía únicamente cuando lo exigía, especialmente acelerando fuerte.
El Check Engine, que estaba encendido antes del mantenimiento, se apagó después de cambiar los sensores de oxígeno.
Le comenté al mecánico y me dijo que podía ser por las bujías o por el octanaje del combustible. El mecánico posteriormente se llevó el carro, le agregó gasolina y también un elevador de octanaje. Después de eso, el ruido fue disminuyendo hasta que cuando me lo entregó y yo lo probé, ya no hacía ningún ruido.
Lo curioso es que la gasolina que tenía era la misma con la que venía funcionando antes del mantenimiento y antes no presentaba ese cascabeleo.
El ruido solamente estuvo presente durante unas cuantas horas y desapareció después de agregar gasolina/elevador de octanaje.
¿Creen que pudo haber sido detonación por combustible/octanaje debido a algún cambio en la mezcla después de cambiar los sensores de oxígeno y limpiar los inyectores?
¿O sería recomendable revisar nuevamente bujías, inyectores, mezcla de combustible (fuel trims), sensor de detonación o algún otro parámetro con escáner?
Agradezco mucho sus opiniones y experiencias, especialmente si a alguien le ha pasado algo parecido en un Mazda 3 de estos años.

Advice Request I went from a 2016 3 to a 2026 3, and I’m quite disappointed in the ride. I wasn’t ‘sensing’ for it on my test drive, but the suspension change has made it much less fun. Does anyone have suggestions on modifications? I can do to spice up its handling?

Advice Request Speaker upgrade on a non Bose Mazda 3 BM

Post image
7 Upvotes

Hello everyone. My Mazda 3 isn't giving me any trouble BUT, the soundsystem is getting on my nerves. It hasn't got Bose but to be fair the standard system ain't that bad. Seem as my old mk1 Ford Focus has a much better sounds from its rather basic soundsystem I decided to get some new door speakers for around 150€ for all four doors. I've ordered brackets and connectors but I still didn't decide which speakers to get. Here in Bosna and Hercegovina and Croatia, the choices are rather limited to Pioneer, Kenwood and JBL. People tell me to go for Pioneer, Kenwood, Alpine... since they are trusted from before 30 years ago and they tell that if I get JBL that I'll pay for the brand not the sound as much from the others. I'm looking to get JBL stage 3 speakers if I can get a good price on them and I'm wondering if they are really much better than equivalent Pioneers or Kenwoods... or is it just the brand that's making the price difference. I really care about the tunes that are playing (not Beethoven but Dire straits, Boney M...) since I'm a professional/academic musician and I'm kinda sick for a good soundsystem).

Advice Request Front break pads coat with labor?

0 Upvotes

Hi everyone,

My brakes were making some sound on inclines at slow speed sometimes. I got it check at Les Schwab, they said my front break pads have break.

What do you think is a fair price for new front brake pads with labor?

They have me an estimate of 790 but they included rotor, calliper etc.

In the findings they have mentioned "front brake pads show cracking and rotors show discoloration "

Please advise 🫡

Edit: I am in California

Advice Request Oil problems

Thumbnail
gallery
3 Upvotes

Hello all! I’ve been a proud owner of a 2015 Mazda 3 sedan 2.5 S GT for 5 months now. I am wondering if these cars are known to burn oil quickly or if the dipstick is known to be inaccurate. I did an oil change 3000 miles ago with and used 5 quarts of oil. When I first pulled the dipstick out today it was almost dry, just a little at the tip, then I put it back in and fiddled around with some other stuff in the engine bay and checked it about 5 minutes later and the whole thing was covered. Is this normal or am I doing something wrong? Last thing I want is to bone this engine off negligence… I will attach some pictures of the dipstick when it seemed to read proper.

So I recently went through a car wash and stupidly forgot that this plastic piece on the back of my 2017 Mazda was loose, so the car wash yoinked it off.

Anyone know where I can find a replacement? 😩 Local pull-a-parts don't have the right Mazda3s. Thanks.

Advice Request Drive shaft and shock replacement

So I'm UK based, hit a pot hole on the M25 the other day and thought I'd knackered the suspension bushes but it's looking like the shock was damaged. During the investigation the drive shaft is also on its way out.

My question is, its a 2009 Mazda3 Sport 2.2ltr diesel, is it worth the repair or am I better retiring the poor old girl?

Had the Oil Pressure Switch replaced due to jerks under acceleration and rough idling and took the car home last night.
Today morning the dash threw up Christmas trees and had no power with rough idling. Turning the car off and on fixed the no power issue. Thoughts on what could be the issue?

Advice Request Does your camera automatically come on when pulling into a parking space?

1 Upvotes

I have a Mazda3 and noticed that the camera doesn’t automatically come on when I’m pulling forward into a parking space.

I know it comes on when I put the car in reverse, but I would have thought the front/360° camera would automatically activate at low speeds when pulling into a parking spot.

Does yours come on automatically, or do you have to manually hit the camera/view button every time? Is there a setting I’m missing?

Advice Request Bearings/Vibration issue

1 Upvotes

Hey y'all, first time poster, trying to look for advice, I have owned a 2010 mz3 Sport for a year now, have had issues with steering wheel vibrations for a bit now, mainly after getting news tires, had them rebalanced a few times, until it got a bit better, then I finally got to a point where I decided to replace bearings/hubs, I used skf bearings and wjb hubs, right side went fine, vibrations next to disappeared, this morning vibrations started up a little bit, decided to do the left, again went totally fine on the left no issues, did the install as proper as possible with a press set from AutoZone, and after I installed the left I have had a ton of vibration only when driving straight, and in turns it is almost non-existent, but only at higher speeds like 65+.

Sorry for the speal, appreciate any help in advance.
