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.
I started this topic way back last year. Nothing has changed. Today I have emailed Mazda Australia with a long list. I finished by saying:
1. I want to turn istop permanently off
2. I want lane monitoring permanently off
3. I want distance monitor permanently off
4. I want the alert/control for exceeding speed permanently off
5. I want to be able to use a cruise control like normal cars
6. I want sensors off
7. When I turn radio off I don’t want it coming on when car is next turned on

I had a cyclist ahead of me in my lane (the only lane). No traffic in oncoming lane. I pulled out to overtake the cyclist and car shuddered on the lane marking and wrenched me back into my lane towards the cyclist.
Cruise Control. Car won’t let me get close enough to a slow car in front to overtake it.
Suddenly BRAKE flashes and brakes come on. Twice. As someone else has asked- I hope my brake lights come on or I’ll be rammed from the rear.
Navigation setting a new search doesn’t always work.
I will give Mazda Australia one last chance. Car cost AUD$45,000. It’s not one year old. Only done 3,000 kms. Anyone want to buy it?

I've found that if you want to override the lane keep assist briefly (like if you pull out to pass a cyclist for example), just hit your signals slightly (like if you set it to auto shut-off after 3 flashers). Not sure if this works with cruise as I haven't tried it.

Our Canadian models don't have the idle stop and go feature, I think this also applies to US models.

I had that experience - and it's also a 'feature' on the Mazda 3 according to my son. I believe I have sorted it so that I only get the BRAKE! alarm in these conditions. I think I just disabled lane control to get this. If I remember, I'll check when I use the car tomorrow.

A polish guy on YouTube - Marek Drives - reviewed the CX30 and noticed the same thing abt accelerating, he said he thought it was the car looking at reducing emissions that caused the lag on accelerating from stopped. I haven't experienced it myself in 3.7k miles(since Nov. '20).

As far as lane assist, yes, using the turn signal helps to override it when you purposely want to go over the lines to avoid cyclists, floods, potholes whatever.

The CX-30 is my first Mazda and it's the first car where the safety assists make it look like the car doesn't trust me to brake, turn the steering wheel etc 😀 Still, if having to make the same choice again I would still probably go for it.

Almost as if you're telling the car, as well as telling other road users ...

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.
I don't think there is anything wrong with your car or your driving ability. The non defeatable safety features produce all kinds of unsavory and irritating effects. Your safety system is deciding you are driving too close to the car in front and, like an ignorant back seat driver with his own steering wheel and brakes, it makes the decision not to accelerate. I have a new CX30 2.5 Turbo which I loved at first and now am seriously thinking of getting rid of. Mazda is no help, they are groveling to the new "woke" culture in which we are all to be "controlled" for our own safety. It is maddening to have purchased a 30+ thousand dollar "performance car" which refuses to perform without permission from an onboard representative of the nanny state.

If there are cars in front of you, then I'd agree it's the car deciding that you can't accelerate because you're too close to the car in front. Irritating as hell. My car was back and to to Mazda from last Aug to this Jan as I had problems accelerating or it would start to then lose power, even with nothing in front of me. Turns out it literally wasn't firing on all cylinders...well not evenly anyway. Had to have data go through UK, Europe and to HO before they got to that. In the end a mechanical issue that a "normal" mechanic should notice but these days there's an over reliance on electronic data to tell them what the issue is. Interestingly when it emergency braked for me out of nowhere, and totally stopped, with nothing in front of me, there was no data in the car to reflect that, so had it caused an accident I would've been left liable, even though I had no control.over the car. You've been warned ⚠

I had MazdaUSA in a chat a couple days ago. I asked them that specific question, "would the system record any safety events?" The answer was "no." You are correct Sarah, if that stupid system gets you in a wreck you're on your own. I want my Jeep back.

@SarahT .. hello Sarah. Do you have the UK Skyactive-G or X engine ?
If you don't mind, could you advise what component/hardware was identified (eventually) causing the flat spot/hesitation, and is the car now accelerating without issue for you ?

I have the UK Skyactive-X, and noticed over the past couple of months a hesitation/flat spot when decelerating<> accelerating, or coming to a short stop then accelerating (can be up to three seconds lag from accelerator application to pick-up).
It's getting worse and I had thought fuel was the problem, but several full tanks of higher grade fuel haven't reduced the flat spot, so will be booking the car into the dealership for investigation.

Having something for them to throw their thoughts at would be helpful.

Thank you.

Hi Paul

Yes, I have an X engine, which although I got last summer I think is actually a Jan 2020 model.

I don't recall exactly what they said, but it was definitely to do with fuel, not the fuel itself, but its distribution. It was either fuel injectors or cylinders, but they were not balanced and so distribution was uneven. Due to a change in job, I don't drive as much anymore, and covid has exacerbated that, but fingers crossed it seems to be fixed now!

Sorry to be vague... don't think I'm firing on all cylinders myself this morning!

Good luck
Sarah

At last someone else saying what I"m finding. Zero acceleration from traffic lights...junctions etc..... dangerous..I have had to press the accelerator multiple times to get a response....terrible delay...will never ever buy Mazda again.
