Does anyone else have this problem? I bought a CX30 new in June 2020. Irregularly, when I’ve slowed down in a traffic queue, then accelerate, I can depress the accelerator to the floor and get no reaction for more than just a few seconds. It is nit a “hesitation” - it won’t go. Twice I’ve almost had cars go into the back of me.
I have no confidence in the car.
Mazda now has the car for management to drive for the third time to try and replicate the problem.which doesn’t happen all the time. The last time I left it, they offered me a driving lesson on modern cars! I bit my tongue.

This car has far too many unnamed buttons. It is ridiculous. It’s impossible to use.
The cruise control doesn’t work.
It is over-sensitive to nearby objects
I loved my 2010 Mazda 3 and wish I still had it
I hate this CX30.
If the non-response problem isn’t fixed this time, I will be going through Consumer Affairs and causing a fuss and demanding a replacement new car.

Sorry to hear of your frustrations, Chris. We can only hope the "hesitation" issue displays itself to Mazda so that they can experience it for themselves. There is definitely something amiss there. However, it sounds like Mazda is committed to resolving the problem so I would bear with them.

On the un-named buttons point, I think Mazda could improve on this front. In my experience, Toyota and Honda (and others) do a much better job of labelling their buttons rather than relying on obscure hieroglyphics. For example, I always do a double take when selecting the windscreen defogger in the CX30 - which button is for the rear and which is for the front?? In my wife's Toyota, the buttons are labelled front and rear so there is much less room for confusion.

puzzled about the buttons, they all seemed to be labelled clearly for me

@Chris when you said it wouldn’t accelerate in a traffic queue could be you were too close to the car in front of you. If so the anti collision system will kick in. If this was the case you need to leave a bigger gap.

Re everything else take the time to learn the car, get your preferred settings locked in and then reevaluate your feelings. This is a good car but you do need to learn it. Hope it all gets better for you.

Thank you all.
I am in Sydney, Australia. My CX30 is Australian model Skyactive G, AWD, 2.5 litre. I have all the “bells and whistles” extras. Still waiting over 6 months for the chrome kit and rose gold key.
My husband is the techno one. I am not young, and this is likely the last new car that I will buy. I am not happy.
The non-response problem has occurred about 8 times. Remember, we are in COVID-times, and the car hasn't been used much. Only done 1,000 kms.
The last 2 times this happened, there was no car in front of me. The last time it happened I was the first car leaving traffic lights - with a (thankfully) patient taxi driver behind me. Twice I was turning, but the last time I was going straight.
I am past being disappointed, now I am angry. I assume the (Australian) Mazda dealer will again keep the car for over a week (no courtesy car offered), and again will say they can’t replicate the problem. I doubt if the service manger will mention a driving lesson for me again!
Responding to the buttons. It’s not the aircon buttons that are hard to work out, but all the others like cruise control. The manual is almost in another language. The navigation manual is online only.

Sorry to hear of your frustrations with your new car, Must say it does sound like a strange thing to be happening to you and could be dangerous if you have an impatient driver behind you.
On the dealer front, i guess all dealerships are different in how they are ran, but i had a cx3 before my cx30 and the reliability and service from my local dealer kept me as a Mazda user.
Hope you resolve your issues and enjoy the car as it is a good car in many respects.

Chris - I can relate to some of your frustration in some respect, I'm in my 70's and due to Covid I've put on less than 2,000 km in six months of ownership.

This is my first vehicle with all the many advance safety systems on and it took a while to get the hang of how they functioned and it wasn't till just recently that I finally mastered the cruise control feature. Because the button actually does three functions I found that I wasn't always engaging the cruise speed the first time as the light would not turn green on my dash light. I have now found that as soon as the accelerate up to the speed, hit the button to set the cruise speed and immediately take your foot off the accelerator - works every time. No mention of that in the manual.
My previous vehicle just had a standard cruise and it would engage as soon as you hit the switch.

You can get the owners manual online, should be from your countries Mazda website. The safety systems does take a bit of getting used too, and it took a while for me to understand how the Mazda Radar Cruise Control with Stop and Go functioned worked in practice. There is also distance adjustments you can set so that it doesn't react the same.

Have you tried driving the car with the i-Activsense switch turned off (default is on) and see if that effects what you are referring too.

I found that just going through a lot of the features with the car in the driveway helped a lot as many can be used in the ACC or ON position without the engine running. Also doing tests on quiet deserted roads or large empty parking lots can sometimes help.

If the dealer can't replicate what you are saying, you should go out with the tech guy so that he can see how you drive and perhaps suggests some things or you can show him what's you think has been happening.

It can be frustrating at times, learning how things function and operate but you slowly get the hang of it, but with the lack of normal driving these days it can take longer to learn. I'm very please with my CX-30, initially I thought I had some problems with it, but after a while I found it was me and not used to how many things functioned, now I'm more comfortable with it.

My break warning alarm sometimes activates for no reason. Fortunately I can replicate this problem in my street.

I am worried it will break and somebody will crash into the back of me.

Yes, I've had the same issue many times. It's a real pain!
Even with MRCC turned off, it still happens.
Apparently according to some owners, the issue goes away after about 5000km. That sounds strange to me.

Behavior like this happens on my model too. But only when there's a car in front of me that's relatively close or might possibly get close. If it happens without anything in front I would recommend getting the sensors looked at. Perhaps MRCC shows a vehicle/object that actually isn't there. For me it happens when switching lanes on the highway and my speed is higher than the car in front, even when the car in front of me is obviously accelerating. The accelerator just stops working for a bit so the car won't allow acceleration.

It also happens at traffic lights, after coming to a halt or close to it and then accelerating again, usually when there's a car in front. Once however it also didn't allow acceleration without any car in front of me, but after an engine software update that seemed to not be happening anymore and now it's only with cars in front when I accelerate slightly quicker than the car in front of me. Annoying when the car in front of me is planning to switch lanes and I should already be accelerating.

It's an automatic though and using kickdown does somewhat override it, at the cost of a lot of noise obviously. I find the feature to be rather annoying and the delay for it to get going again is quite long. On the other hand it doesn't decelerate either. I find it a problem, but it's also practically impossible to reproduce on command.

I seem to be the only one stressing the danger in this. It has happened to me 3 times when it’s been dangerous. I’ve been coming out of shopping centres and waiting to give way to oncoming traffic. When I see an opening I put my foot down- as does the car behind me. My CX30 does not respond and I have nearly been hit both by the car behind me, and the oncoming traffic. I have no confidence in the car. I don’t want it. Mazda (I’m in Sydney, Australia) has had it now for 2 weeks and it’s the third time they’ve had it. I will be selling it.

Ask dealer to update the software. However it sounds to me like some sensors aren't working properly or the transmission/engine is having issues. Such extreme effects aren't normal at all and definitely go further than my experiences.

happened to me 2 months after getting it. A motorbike touched my rear bumper when the car decided to brake on its own (street was empty). Mazda wasn't that sympathetic and told me I probably pressed the gas pedal ad brake pedal at the same time (I told them no as the car has an error for that if need be). Obviously, Mazda wasn't understanding or helpful about the situation and I'm still waiting for an answer or solution almost 9 months on

There was a software update combined with a recall that should've fixed this. At least for the Mazda 3. I know some earlier CX-30 had the same problem.

The braking issue isn't the same as the not accelerating issue. Although both could be caused by misinterpreting the sensor data.

I have had similar problems to the OP as well as loss of power issues and random emergency braking. The data has been to Mazda UK, then Mazda Europe and then to the HO. They now have my car back.in the garage again and are having to take it apart to look at individual parts for the issue. To be fair they are taking it seriously, which is good considering I've been left in some massively dangerous scenarios! There is definitely something not right with these cars!! Oh and just as a point of interest I dont have buttons marked front & rear either and I also can never remember which one to press!

Yes. I have this issue. Especially after turning onto a street.

I am very disappointed with the low end acceleration from the car - particularly from a 2 litre engine that has 186HP. I now make a point of changing down to second to turn a sharp corner - which should be unnecessary.
