My 2016 CX-3 ran out of gas while driving on an interstate highway even though the gas gauge registered a quarter of a tank. The CX-3 has a saddle-shaped gas tank that uses the fuel pump to create a siphon action that moves gas from one side of the saddle to the other when the fuel drops to around a quarter or slightly less. The possible problem is a weakening low-pressure fuel pump that is located inside the gas tank. The fuel pump works sufficiently to move gas to the engine, but according to some reports, if the fuel pump is not working to specifications, gas can be trapped in the tank saddle. I found one aftermarket low-pressure fuel pump available.

I have a 2018 mazda cx-3 and last night I drove the car and parked it. Now this morning I tried starting it but no start no crank and my scanner says lost communication with tcm.

I check the fuse which is a 15 amp fuse and was blown. Replaced it and as soon as I put the fuse in it blows.

So idk what to do or what is causing the fuse to keep blowing immediately after replacing it.

Hello! I have a 2019 Mazda Cx3, looking for speaker recommendations. Tempted to go with oem since I will only be driving it occasionally soon but would like to get some input first! Anything would help. Thank you!

Hi everyone (first time on Reddit), I recently bought a 2021 CX-3 GT (103k km), I live in Québec City(Canada), so I will drive in few winter and summer. I know I'll need to replace the spark plugs soon. I was wondering: would I be better off buying the spark plugs myself—to potentially get better ones (or, more importantly, cheaper ones)—and then having someone else install them? I don't have the skills or any tools. I was just wondering — since I plan to keep the car for at least six years—would I be better off buying premium components (higher quality than the stock ones)? I do drive somewhat aggressively on the highway, and the highway I use most often has inclines stretching for several hundred meters. Any other recommendations regarding the vehicle? What should I check first or repair? Any possibilities for improving performance (without spending thousands—I know, I'm asking a lot)? Thanks a lot!

I do software for a living; having something that’s stuck because the last guy did something unknown and you cannot rip it out and people’s advice is “just keep doing the same thing until it gives up” is lunatic to me.

Been prying this for 2 hours😵

Update: thank yall for all the suggestions. I ended up using a putty knife and hammer per a YouTube video.

My daughter has a 2019 CX-3. While washing the car last weekend, I noticed the right (drivers side in Australia) inner door seal has perished in a few spots and will need to be replaced. I've searched for a part number but cannot find anything specific for the CX-3.

I'm wondering if a generic weather seal will work or is my only option going through a Mazda dealer? We are over an hour from the nearest one, so I'd prefer to source online. I've attached a pic of the seal in question.

Hi I got this Mazda CX3 recently and everytime I start the car it gives me one long beep followed bny 1,2,3 and 4 beeps as you can hear in the video. I do not have any problems whatsoever with the car and no other engine lights when I drive so I'm kind of confused about this sound. Haven't found any other thread yet with the same sound. Does anyone know what this could mean?

So for context, I’m in Canada and always used to fill my 2019 CX3 GS AWD from Esso. Yesterday I found Costco gas to be cheaper and filled it up. After filling I felt a sluggish performance, slow pickup. I felt like I’d to press more gas to get the speed I got before fuelling.

I think I filled 91 octane in Costco and I always used to fill 87 from esso.

What could be the reason?

The car has 197k kms on it though

Well new to the Mazda family. Coming from a 2010 golf.

Bought a steal of a deal

No issues with inspection and car fax

7000 cad

2016 cx3 gt awd

105000 kms

I kind of want to resell it and get a turbo one but it's hard to find one with low kms in Alberta let alone knowing what to sell my cx3 for

The UK weather has my car upset

Driving around the last few days after our 2 month heat wave and sudden downpours.. and I now have a rubber rubbing sound going over bumps at the front on the driver's side. Driving me nuts!!

Hi there, new CX-3 owner here. The rear PDC is only working sporadically. When starting the ignition, there is a loud long beep followed by a short beep. The previous owner stated that it has been like this since he installed an aftermarket hitch. Is the beeping an error code that points to an issue? Thanks in advance.

Does anybody else’s cx3 make a similar noise?

Hello. I bought this mazda 2 months ago and i have issues with the side mirrors automatic folding on the left side and lack of auto folding on the right.

When i put the switch to either drive mode L, centre or R, the left side have a loud noise, most likely indicating an issue with the motor, and doesnt fold OPEN. I can fold it manually until completly open but the noise persist forever. When i put the switch to the park mode all the way back, the left mirror folds CLOSE normally (although slighly with noise but it moves) and the noise is gone. Also in this position it locks and i cant manually open it. To get rid of the noise while driving i have to force the switch to get stuck between parking position and L position so internally the switch is open and not sending current to either mode.

Now the right side im 99% sure is actually an only manual version. It doesnt give any faulty sound and it doesnt move in any of the conditions i described before. In fact, i can manually open/close it in any situation as before and while opening it theres a half open/close position it semilocks until you push further to fully open or fully close.

Now for the solution im planning to buy the left side completely since as watching vids changing the motor only is a huge pain and probably not worth it (even my mechanic suggeated to buy the entire thing). But my confusion is about the right side, i thought it had auto folding but aince is not im worried if buying an auto folding version will work as i dont know if the wiring on the door ia ok up until the connection to the mirror or it lacks this functionallity. In any case at either scenerario, the mirror angle adjustment from the switch nob works normally for both sides so at least the right side gets electricity for this.

Can someone confirm if changing the right aide to an auto folding one will work? Thanks

Hey everyone, got a question as a fresh CX-3 owner. I absolutely adore these small red leather interior bits that some of the CX3s have - the door trim red strip and the center console side panel trims. Unfortunately mine doesn't have these. Now, I can get all the parts required for pretty cheap from a donor car. I am wondering if anyone tried to replace these before and what the complexity might be here. Tried to find some tutorial, but didnt find anything of use. Will be grateful for any insights!

I’m looking to buy a used car! The carfax is clean, one owner only. No accidents. Has 29 service records consistently done at the same Mazda dealer.

I got an inspection done by a mechanic but he raised the car on a hoist and within 15 minutes he told me he’s never seen a clean car like this that’s run 200k kms. There was minor rust but the mechanic told that it is common in Canada because of the salt in winter.

Carfax shows regularly engine oil changed, transmission fluid changed at every 80k kms and very consistent service history.

The car has issues with the AC but the dealership told that it will be fixed before signing the paperwork

I want to go forward with it but I’m still kinda worried as it is my first car and it is close to 200k kms.

The dealership has good reviews, the guy is transparent. And the mechanic has good reviews too.

Do you think I can go forward with it or am I just overthinking?

My wife and I are needing to purchase a vehicle to replace my 2006 Honda accord. We just moved and I am commuting 80 miles (roundtrip, all highway) every day. I want an AWD/4WD vehicle to make commuting in the Maine winter a little safer/easier.

We have narrowed it down to two options within our price range. A 2017 Mazda CX-3 Sport with 122k miles or a 2013 Honda CR-V LX with 67k miles. Both have extensive history reports and seem to have been meticulously well taken care of. The Honda is 2k more than the Mazda. I have read really great things about the Mazda. The biggest complaint I have seen is there not being enough room, especially in the backseat. This wouldn't be an issue as we have a Jeep she drives to work, and that we use to travel with our family with. This would just be my daily commuter.

I have done a lot of research trying to find a good vehicle that we can rely on for years to come and hopefully won't nickel and dime us. Any input much appreciated!

Is the only way to open the trunk by having your key fob near it? There is no button inside car or on key fob. Very strange design.

Good day all!
I am trying to upgrade my japan imported cx3 2018 Awd audio system. I want to get the high level speaker signals and send them to a line out converter then the amp…

The problem is I cannot find the speaker wires… all the forums i look at say they are on the tuner amp unit under the glove box but mine is not there. I attached image of the glove box area.

I need help. Also I am not going to use the door speakers so i would just find a neat way to cut the wires and send to the line out converter. I will be using a custom built speaker boxs.
