r/MazdaCX30

Fuel economy for the cx-30 is commonly discussed here but I don’t think the particular discussion has occurred.

For context, my 2011 Honda accord is on its last leg and I am looking to buy a new car. I primarily have short commutes in-town but also do out-of-state trips (300mi each way) every other month. After a lot of online research and test drives, I have narrowed it down to the 2026 Mazda cx-30 non-turbo (preferably carbon edition, love that red leather) or the 2026 Honda civic hybrid hatchback touring. I love the Mazda for all the reasons everyone here does - wonderful styling inside and out, comfortable but sporty ride, engaging steering, etc. I was also pleasantly surprised by the civic, especially how well it accelerated with the hybrid drivetrain. Overall, the Mazda was more enjoyable to drive and simply be inside of, but the civic was not miles behind in that regard. The biggest thing holding me up from being 100% in on the cx-30 is fuel economy.

Now for the actual question: for the folks on here with a cx-30 (presumably most of you given the name of the subreddit), how has the fuel economy/range affected your enjoyment/satisfaction with the car? Do you ever wish you had purchased a hybrid?

I recently bought a 2023 Mazda CX-30 with milaegae of 40,000; and my average fuel economy is only around 23.8 MPG. I mostly do city driving, but I feel that’s a little low.

I’ve also noticed that when accelerating from a stop, such as at a traffic light, I have to press the accelerator quite a bit, which causes the RPM to rise noticeably. Because of this, I’m wondering if it’s affecting my fuel economy.

Is this normal behavior for the Mazda CX-30, or could there be an issue with the car’s acceleration or transmission? Do other Mazda owners experience similar pickup and RPM behavior after coming to a stop?

2022 Turbo Premium with just over 50k. I had a rubbing/grinding noise for a bit, but assumed it was the brakes that needed fixing as they were due for replacement. Had the brakes done this morning. The mechanic called and informed me that there was still a “roaring” sound due to the rear differential.

Managed to get a dealer appointment immediately after, somehow. Thanks, universe. The dealer diagnosed the issue as the transfer case. Replacement part is on back order until March. Should hear back from the dealer tomorrow about the long term plan, but horrified about the prospect of having to figure out alternative transportation for the next 6+ months if they won’t provide a car.

Has anyone else dealt with something like this, and did you have any luck with Mazda providing transportation while waiting on the part? 😬

The one upside is that, at least for a couple of days, I’m in a brand new TPP. It drives like a dream.

This weekend I changed my shocks and struts and replaced the brakes and rotors. After assembling everything and driving the car it has a loud hum that sounds like a vibration (no actual vibration) that gets louder after 5 mph. I tried driving it to see if it could be brake pads rubbing and after hitting 60 mph I got an ABS, stability control and engine malfunction warning.

I jacked the tire and checked for looseness. The pads seem like they might be rubbing but why would the engine lights come on? The brake fluid appears high after pushing in the caliper piston. I didn’t add any fluid.

Thoughts?

So my 2022 cx30 2.5L non turbo with 63,000km on it would not start for me on Sunday. I was in the store for MAYBE 5 mins. When I came out to start the car, The brake pedal was stiff as a rock and as I pressed the start button only the acc came on with the lights on the dash. I dont think any icons came up at this point. I called my boyfriend he came and he tested the battery it was reading 12.4. He checked all the fuses and they all looked good. At this point we noticed the green key icon with the exclamation mark stating low key battery, so we went and changed the fob battery. Still nothing. We tried disconnecting the battery terminals and cleaning them.. still nothing,

At this point he pulled out the cables and tried jumping the car and still nothing... So we went and purchased a new car battery as most forums said to try that. ( even though the current battery is only about 5months old and is after market NOT OEM. ) Tried the new battery and nothing. At this point i noticed the battery icon, engine light and power steering light on my dash.

At this point we had the car Towed to Mazda. Monday morning at 7:45 am mazda calls (fantastic service time btw) and stated that the car started perfectly fine this morning. They assessed and looked at the battery, starter cables, altinator and serpentine? Belt. Also the lights on my dash are all gone. They did change my carbon air filters and engine air filters and didnt charge me for the diagnostics.

My theory is that maybe there's a loose wire somewhere and the tow truck shook it back into position. (thats my uneducated guess lol) Has anyone had any issues like this where changing the battery was not the solution? I'm happy the car is running but im scared it will happen again and I will get stuck again.

EDIT* I want to add that we took the new battery out and returned it and put the old battery back in because it tested fine.

Just got this car and love it. What's the best dash cam for it, preferably front and rear

Just received my new to me 2025 GS Luxury package. Will post beauty shot tomorrow.

Looking for advice on where to get a nice deal on 215/60R17 snow tyres and steel rims in the Toronto area.

The car has under 10k kms at the moment on factory Bridgestone tyres.

Does anyone have experience using Costco’s partnership with Car Keys Express to have another fob made? Bought used and it only came with one and I’m looking for personal experiences using their service. Don’t know the exact price but I’m sure it’s more than half the dealership price and potentially better than locksmith pricing.

UPDATE: I went today and was quoted $289.99, about 10-15 minutes into my shopping, I was notified they were unable to do it due to “Mazda’s updated software”. Guess I’ll be buying a fob online and finding a local locksmith to help.

Hi! I will preface this by saying, I do not keep food in my car. I don’t eat food in my car. There is no food in my car. I drive a 2024 Turbo Premium Plus, and I am the first and only owner. I keep finding fully grown roaches, thumb-sized or larger, in my car. Nothing small and no babies. I have had the car detailed and fumigated, and I have since moved into a more urban area than before. Tonight, I found another roach. Is there a common hole in the car I’m not aware of on the outside? Is this an issue anyone else has had before? Is it because I live in Florida (but never happened to my previous car)? Is there anything I can do other than call the dealer to look? Thank you so much in advance!
