This error just popped up this morning going to work.

It didn’t go away after I turned the engine off and back on.
The car has only 10k miles.
Has anyone had anything similar?
What as the issue?

Would the cx-30 fit a tall person?

As the header asks would the cx-30 fit a tall person? I'm looking for a new car as my Camry is starting to give out on me and it's mileage is getting up there. I'm 6'8 so trying to find a more affordable SUV that would fit me is a bit challenging so I'm really hoping someone here says I could fit it in the cx-30 as it looks like a really nice car.

2026 Preferred OTD?

Hi all! After months of researching, test driving etc, I know that a CX-30 preferred is for me! Originally I wanted to go with a used but used prices with the amount of miles on a 1-2 year car are insane. This is my first dealer sheet from one dealer and I just want to see overall what was others OTD prices on the 2026 or 2025 Preferred so I know not to lowball but also not get fucked over. (Also for taxes if it matters it’ll be Illinois for this specific one or Missouri as I live between both).

Talk me out of it

Good morning everyone.

I went to the local Mazda dealership yesterday to look at cx5s and cx50s. They ended up being slightly more expensive than I wanted to pay. The dealer then suggested I test out a cx30. The only model they have is a carbon edition and it looks really nice. It handles really well, but my main complaint is that the driver's area seems really small. My left knee hits the door panel where all the buttons are.

I would be trading in my older rav4 with around 100k miles. I can't decide if it's worth it to buy something new, or just fix up my rav4 and drive it until the wheels fall off

Fuel cleaner help!

I have recommend by a friend of mine to use this annually for carbon buildup, so the engine can last longer and efficient. I bought my CX-30 last year, is it a good idea to use this? Any advice would help!
Thanks

Would it be a good idea to by a 5quart 0W20 with the predicted motor oil shortage?

Just curious about this. I go to the dealership or an independent shop to have my oil changed about twice a year. So if they don't have oil in a few months, then I'd be cooked.

Would it be a good idea to buy a 5 quart to keep it at home just in case?

Does the CX-30 have any particular issues to be aware of when buying used?

I’m in Australia and looking for a used car. An Australian reviewer (ReDriven) made a very negative review of the CX-30 citing issues like thin paint, creaking interior and oil dilution. I’d appreciate it if real owners can share their opinion about this car. Thank you.

AC issues 2021 Mazda cx30

Hello to everyone disclaimer I am a Honda tech not a Mazda tech, but my wife owns a Mazda so I take care of all her maintenance. Please do not work on any AC units unless certified under 609 certification.

About a week ago, her AC gave out. I took it to my shop and started diagnosing. The problems. Condenser fan was working when the AC was on the clutch was engaging. All fuses were working perfectly fine and no strange noses can be heard. I checked all for the high and low pressure and everything was correct. I recovered all the Freon in the system and placed it back and it still did not work. After further looking into this matter I found something strange a little sensor coming from the compressor come to find out it’s a compressor control valve OEM part number BDGF61450. (Part is show in the above picture). That little valve controls if your compressor actually compresses or just spins. After changing that one valve AC was charged and back to working as normal. I see a lot of people complaining for a new compressor and the over charge for parts and labor but 50 dollars and a Freon R-134a may solve this issue. Any comments questions or concerns please feel free to contact me for help.

Trunk door won't open without key fob nearby

What the title says, the trunk doesn't open unless I'm standing next to it with the key fob.

Doesn't matter if I unluck the doors from the fob, from the driver's door, if the car is in park, drive, on, off , if I don't have the key with me it won't open.

Any ideas what it might be?

2026 Select Sport (ceramic metallic) question

Bought this new back in April. I noticed recently (this week) that it feels more snappy. I'm at roughly 1100 miles. Does the ECU restrict performance during break in? Shifting feels a bit snappier, and mid range pull feels a bit stronger. I did get on it a bit after I hit the 600 mile break in. So I'm fairly confident it's not in my head. Just curious!

Joined the club yesterday.

I did it all through Carvana and they made it a very easy process. Love my CX30 so far! The only big drawback for me is that the USB plugs are only in the center console. Does anyone have recommendations for good phone mounts for the dash?

New owner half-paranoid questions

Hi everyone,

I bought my CX-30 just a week ago and had a couple of drives, I have some anxiety-driven questions for those who bought it new, to check if they had similar experiences.

  1. Consumption. I expected it to be somewhat higher than the declared one (6L/100km or 39mpg) but I get +50% consumption with respect to these numbers, with a normal mixed driving, half city / half highway. My motor is a Skyactiv-G 2.5L (non-turbo, 2025 version). Could this be related to being the first kilometers and maybe it should drop with time? I read it somewhere but I'm really unsure about this.
  2. Smell: the engine bay has a slight burnt smell after a trip. It seems to me it is fading, I just had 200km in the car. Is this regular / has someone else experienced this? (eg. just new rubbers / coatings / ... setting in maybe?). The engine bay is hot after a trip, but the temperature reported on the screen is normal. So it does not seem alarming.
  3. Air from air vents. With AC off, the air at the "Lo" setting is still way hotter than the exterior. Yesterday the outside was fresh (18C /64F), but the flow the air vents was not very comfortable even after a long time, and I resolved the old shool way - windows partially down. With my older car, letting air flow at "Lo" meant air at the same temperature as outside was flowing in. Maybe it is the hot engine bay that pre-heats air anyway?

Thank you very much! I'm still absorbing the shock of modern driving.

2021 Mazda CX-30 Premium vs 2021 Subaru Crosstrek Limited

Looking to buy one of these two. The mazda has ~55k miles on it and would be from a dealership. The subaru is from a friend that I wholeheartedly trust. Similar prices since I'm avoiding the dealership with the subaru. I'm just curious if people have any experience/thoughts on these. thanks everyone

Edit: is anyone familiar with the remote start options for the subaru?

Driver aids/ steering assist lacking

I have a 21 tpp. My wife has a mid trim 2019 Honda crv. I love the traffic jam assist in my car but hers has infinitely better/stronger lane keeping assist at high speeds. It really lessens driver fatigue on longer drives. I am disappointed that my Mazda doesn’t have that.
